  4. Charles Darwin in the Andes (United States)

    Bizzo, Nelio; Bizzo, Luis Eduardo Maestrelli


    Considering geological time as an important epistemological obstacle to the construction of ideas on biological evolution, a study was carried out on the so-called "Darwin Papers". The conclusion was that Charles Darwin's excursion in the Andes during March-April 1835 was a crucial step in this regard. An expedition was carried out in…

    The year 2009 is the bicentenary of the birth of Charles Darwin and the 150th anniversary of the publication of On the Origin of Species. This article briefly surveys his life and work, dispelling some common myths and summarizes Darwin's achievement and legacy at his death in 1882.

  6. Charles Darwin: genius or plodder? (United States)

    Wilkins, Adam S


    There is no doubt about the magnitude of Charles Darwin's contributions to science. There has, however, been a long-running debate about how brilliant he was. His kind of intelligence was clearly different from that of the great physicists who are deemed geniuses. Here, the nature of Darwin's intelligence is examined in the light of Darwin's actual style of working. Surprisingly, the world of literature and the field of neurobiology might supply more clues to resolving the puzzle than conventional scientific history. Those clues suggest that the apparent discrepancy between Darwin's achievements and his seemingly pedestrian way of thinking reveals nothing to Darwin's discredit but rather a too narrow and inappropriate set of criteria for "genius." The implications of Darwin's particular creative gifts with respect to the development of scientific genius in general are briefly discussed.

  7. Charles Darwin and John Herschel (United States)

    Warner, B.


    The influence of John Herschel on the philosophical thoughts of Charles Darwin, both through the former's book, Natural Philosophy, and through their meeting in 1836 at the Cape of Good Hope, is discussed. With Herschel having himself speculated on evolution just a few months before he met Darwin, it is probable that he stimulated at least the beginnings of the latter's lifelong work on the subject.

  9. Charles Darwin's earthquake reports (United States)

    Galiev, Shamil


    As it is the 200th anniversary of Darwin's birth, 2009 has also been marked as 170 years since the publication of his book Journal of Researches. During the voyage Darwin landed at Valdivia and Concepcion, Chile, just before, during, and after a great earthquake, which demolished hundreds of buildings, killing and injuring many people. Land was waved, lifted, and cracked, volcanoes awoke and giant ocean waves attacked the coast. Darwin was the first geologist to observe and describe the effects of the great earthquake during and immediately after. These effects sometimes repeated during severe earthquakes; but great earthquakes, like Chile 1835, and giant earthquakes, like Chile 1960, are rare and remain completely unpredictable. This is one of the few areas of science, where experts remain largely in the dark. Darwin suggested that the effects were a result of ‘ …the rending of strata, at a point not very deep below the surface of the earth…' and ‘…when the crust yields to the tension, caused by its gradual elevation, there is a jar at the moment of rupture, and a greater movement...'. Darwin formulated big ideas about the earth evolution and its dynamics. These ideas set the tone for the tectonic plate theory to come. However, the plate tectonics does not completely explain why earthquakes occur within plates. Darwin emphasised that there are different kinds of earthquakes ‘...I confine the foregoing observations to the earthquakes on the coast of South America, or to similar ones, which seem generally to have been accompanied by elevation of the land. But, as we know that subsidence has gone on in other quarters of the world, fissures must there have been formed, and therefore earthquakes...' (we cite the Darwin's sentences following researchspace. auckland. ac. nz/handle/2292/4474). These thoughts agree with results of the last publications (see Nature 461, 870-872; 636-639 and 462, 42-43; 87-89). About 200 years ago Darwin gave oneself airs by the

  10. Charles Darwin, beetles and phylogenetics. (United States)

    Beutel, Rolf G; Friedrich, Frank; Leschen, Richard A B


    Here, we review Charles Darwin's relation to beetles and developments in coleopteran systematics in the last two centuries. Darwin was an enthusiastic beetle collector. He used beetles to illustrate different evolutionary phenomena in his major works, and astonishingly, an entire sub-chapter is dedicated to beetles in "The Descent of Man". During his voyage on the Beagle, Darwin was impressed by the high diversity of beetles in the tropics, and he remarked that, to his surprise, the majority of species were small and inconspicuous. However, despite his obvious interest in the group, he did not get involved in beetle taxonomy, and his theoretical work had little immediate impact on beetle classification. The development of taxonomy and classification in the late nineteenth and earlier twentieth century was mainly characterised by the exploration of new character systems (e.g. larval features and wing venation). In the mid-twentieth century, Hennig's new methodology to group lineages by derived characters revolutionised systematics of Coleoptera and other organisms. As envisioned by Darwin and Ernst Haeckel, the new Hennigian approach enabled systematists to establish classifications truly reflecting evolution. Roy A. Crowson and Howard E. Hinton, who both made tremendous contributions to coleopterology, had an ambivalent attitude towards the Hennigian ideas. The Mickoleit school combined detailed anatomical work with a classical Hennigian character evaluation, with stepwise tree building, comparatively few characters and a priori polarity assessment without explicit use of the outgroup comparison method. The rise of cladistic methods in the 1970s had a strong impact on beetle systematics. Cladistic computer programs facilitated parsimony analyses of large data matrices, mostly morphological characters not requiring detailed anatomical investigations. Molecular studies on beetle phylogeny started in the 1990s with modest taxon sampling and limited DNA data. This has

  13. The first Charles Darwin (1758-78). (United States)

    Harris, Stuart


    The paper places the first Charles Darwin in his family context: the eldest son of Dr Erasmus Darwin and Mary Howard. Mention is made of Charles's upbringing and education, with illustrative material taken from his father's writings and from Anna Seward's Memoirs of the Life of Dr Darwin (1804). The part played by Dr Andrew Duncan of the Edinburgh Medical School is established. The award to Charles in March 1778 of the first medal by the Aesculapian Society of Edinburgh is described. The involvement of Dr William Cullen and Dr Joseph Black in the treatment of Charles's fatal infection is evidenced from Erasmus' letters. Attention is given to 'An Elegy on the much-lamented death of a most ingenious young gentleman who lately died in the College at Edinburgh where he was a student' which was written jointly by Duncan and Erasmus in 1778. The Elegy's curious publishing history will be glanced at. The paper concludes with a statement of Charles's great promise as a medical student and of Erasmus' efforts to ensure that his son's achievements were memorialised.

  14. Charles Darwin and the origin of life. (United States)

    Peretó, Juli; Bada, Jeffrey L; Lazcano, Antonio


    When Charles Darwin published The Origin of Species 150 years ago he consciously avoided discussing the origin of life. However, analysis of some other texts written by Darwin, and of the correspondence he exchanged with friends and colleagues demonstrates that he took for granted the possibility of a natural emergence of the first life forms. As shown by notes from the pages he excised from his private notebooks, as early as 1837 Darwin was convinced that "the intimate relation of Life with laws of chemical combination, & the universality of latter render spontaneous generation not improbable". Like many of his contemporaries, Darwin rejected the idea that putrefaction of preexisting organic compounds could lead to the appearance of organisms. Although he favored the possibility that life could appear by natural processes from simple inorganic compounds, his reluctance to discuss the issue resulted from his recognition that at the time it was possible to undertake the experimental study of the emergence of life.

  15. Charles Darwin: um observador do desenvolvimento humano

    Directory of Open Access Journals (Sweden)

    Eloisa Helena Rubello Valler Celeri


    Full Text Available Os autores traduzem, pela primeira vez para o português, o artigo de Charles Darwin "A Biographical Sketch of an Infant", publicado no periódico Mind em julho de 1877. Utilizando anotações de observações do desenvolvimento de seus filhos, especialmente de seu filho mais velho William Erasmus (Doddy, Darwin descreve e estuda, a partir de seu enfoque naturalista, o filhote humano, narrando os primeiros indicativos comportamentais de emoções tais como raiva e medo, curiosidade e senso moral, o brincar e o prazer envolvido nesta atividade, a capacidade de imitação e os primeiros indícios daquilo que hoje conhecemos como "teoria da mente". Colocando-se questões sobre as capacidades do bebê, como eles aprendem e como se comunicam e levantando hipóteses sobre possíveis significados de certos comportamentos, questões ainda hoje fundamentais para o estudo do desenvolvimento humano, Darwin mostra-se também um pioneiro no estudo do bebê e da criança pequena, numa época na qual as capacidades dos bebês eram extremamente subestimadas e desconsideradas.

  16. Evolutionary plant physiology: Charles Darwin's forgotten synthesis. (United States)

    Kutschera, Ulrich; Niklas, Karl J


    Charles Darwin dedicated more than 20 years of his life to a variety of investigations on higher plants (angiosperms). It has been implicitly assumed that these studies in the fields of descriptive botany and experimental plant physiology were carried out to corroborate his principle of descent with modification. However, Darwin's son Francis, who was a professional plant biologist, pointed out that the interests of his father were both of a physiological and an evolutionary nature. In this article, we describe Darwin's work on the physiology of higher plants from a modern perspective, with reference to the following topics: circumnutations, tropisms and the endogenous oscillator model; the evolutionary patterns of auxin action; the root-brain hypothesis; phloem structure and photosynthesis research; endosymbioses and growth-promoting bacteria; photomorphogenesis and phenotypic plasticity; basal metabolic rate, the Pfeffer-Kleiber relationship and metabolic optimality theory with respect to adaptive evolution; and developmental constraints versus functional equivalence in relationship to directional natural selection. Based on a review of these various fields of inquiry, we deduce the existence of a Darwinian (evolutionary) approach to plant physiology and define this emerging scientific discipline as the experimental study and theoretical analysis of the functions of green, sessile organisms from a phylogenetic perspective.

  17. Creative work. The case of Charles Darwin. (United States)

    Gruber, H E; Wallace, D B


    The evolving systems approach (ESA) addresses the need for direct study of the creative process in recognized creators at work, in contrast to indirect methods, such as those used in psychometric studies. The ESA emerged from H. E. Gruber's prolonged study of Charles Darwin's manuscripts, especially the notebooks he kept after the Beagle voyage. Gruber's interviews with J. Piaget about the latter's creative processes, as well as many doctoral dissertations, also helped shape the authors' approach. Using Gruber's (1974/1981) study of Darwin, the authors describe some facets of creative work identified in the course of their work. Among these are networks of enterprise, ensembles of metaphors, insights, and evolving belief systems. Although the ESA emphasizes cognitive processes, social, affective, and esthetic aspects of the case are not neglected. Each creative case is unique, otherwise the individual would not meet the criterion of originality. Uniqueness does not mean isolation; people who differ must and do work together. The integration of all these facets into a plausible system for each creator remains the authors' central task.

    This article traces the personal as well as the intellectual and scientific relationship between Charles Darwin and his younger half-cousin Francis Galton. Although they had been on friendly terms as young men, and Darwin had in some ways been a role model for Galton, the two did not share major scientific interests until after the publication of…

    Full Text Available 150 years ago, Heinrich Bronn provided in the first German translation of Charles Darwin's Origin of Species a rather liberal interpretation, even adding his own view of Darwin's ideas in an additional 15th chapter. Ernst Haeckel widely popularized his view of Darwinian evolution based on his reading of this translation. This was long seen - probably incorrectly - as the intellectual root of social Darwinism in Germany.

  1. Like grandfather, like grandson: Erasmus and Charles Darwin on evolution. (United States)

    Smith, C U M


    Last year (2009) marked the bicentenary of Charles Darwin's birth and the sesquicentenary of The Origin of Species. This article examines the influence of Erasmus Darwin on Charles's evolutionary thought and shows how, in many ways, Erasmus anticipated his much better-known grandson. It discusses the similarity in the mindsets of the two Darwins, asks how far the younger Darwin was exposed to the elder's evolutionary thought, examines the similarities and differences in their theories of evolution, and ends by showing the surprising similarity between their theories of inheritance. Erasmus's influence on Charles is greater than customarily acknowledged, and now is an opportune time to bring the grandfather out from behind the glare of his stellar grandson.

  2. Charles Darwin's Theory of Moral Sentiments: What Darwin's Ethics Really Owes to Adam Smith. (United States)

    Priest, Greg


    When we read the Origin, we cannot help but hear echoes of the Wealth of Nations. Darwin's "economy of nature" features a "division of labour" that leads to complexity and productivity. We should not, however, analyze Darwin's ethics through this lens. Darwin did not draw his economic ideas from Smith, nor did he base his ethics on an economic foundation. Darwin's ethics rest on Smith's notion from the Theory of Moral Sentiments of an innate human faculty of sympathy. Darwin gave this faculty an evolutionary interpretation and built on this foundation an ethics far removed from what is commonly supposed.

  5. John Tweedie and Charles Darwin in Buenos Aires. (United States)

    Ollerton, Jeff; Chancellor, Gordon; van Wyhe, John


    The journey of exploration undertaken by Charles Darwin FRS during the voyage of HMS Beagle has a central place within the historical development of evolutionary theory and has been intensively studied. Despite this, new facts continue to emerge about some of the details of Darwin's activities. Drawing on recently published Darwin material and unpublished letters in the archives of the Royal Botanic Gardens, Kew, we document a hitherto unexamined link between Darwin and John Tweedie (1775-1862), a relatively obscure Scottish gardener turned South American plant collector. All of the available evidence points to a meeting between the two men in Buenos Aires in 1832. Tweedie provided Darwin with information about the geography of the Rio Paraná, including the locality of fossilized wood eroding from the river bank. It also seems likely that Tweedie supplied Darwin with seeds that he later shipped back to John Stevens Henslow in Cambridge. Although this brief meeting was at the time relatively unimportant to either man, echoes of that encounter have resonated with Tweedie's descendants to the present day and have formed the basis for a family story about a written correspondence between Darwin and Tweedie. Local information supplied to Darwin by residents such as Tweedie was clearly important and deserves further attention.

  6. Did Jean François Barbe Anticipate Charles Darwin? (United States)

    Drouin, Anne-Sophie; Drouin, Emmanuel; Pereon, Yann


    The publication of Charles Darwin's On the Origin of Species in 1859 is widely suppose to have initiated a revolution in science. In 1837, he broke with dogmatic fixism and argued that the adaptation of populations to their local environment was the cause of transmutation. Some contributors helped him start his reasoning: he indeed expressed his indebtedness to Samuel Rowley for having called his attention to Charles Wells' notions of natural selection. Darwin was certainly not the first to suggest the idea of evolution as an alternative to the creation of species by God. We report on a medical thesis published in 1837 being concluded by an unexpected and important statement related to the appearance of mammals on Earth. It remained unknown but it constitutes a link between the transformative thought of Lamarck and Geoffroy Saint Hilaire, and Darwin's work.

  7. Modelling of Charles Darwin's tsunami reports (United States)

    Galiev, Shamil


    Darwin landed at Valdivia and Concepcion, Chile, just before, during, and after a great 1835 earthquake. He described his impressions and results of the earthquake-induced natural catastrophe in The Voyage of the Beagle. His description of the tsunami could easily be read as a report from Indonesia or Sri Lanka, after the catastrophic tsunami of 26 December 2004. In particular, Darwin emphasised the dependence of earthquake-induced waves on a form of the coast and the coastal depth: ‘… Talcuhano and Callao are situated at the head of great shoaling bays, and they have always suffered from this phenomenon; whereas, the town of Valparaiso, which is seated close on the border of a profound ocean... has never been overwhelmed by one of these terrific deluges…' . He reports also, that ‘… the whole body of the sea retires from the coast, and then returns in great waves of overwhelming force ...' (we cite the Darwin's sentences following researchspace. auckland. ac. nz/handle/2292/4474). The coastal evolution of a tsunami was analytically studied in many publications (see, for example, Synolakis, C.E., Bernard, E.N., 2006. Philos. Trans. R. Soc., Ser. A, 364, 2231-2265; Tinti, S., Tonini, R. 205. J.Fluid Mech., 535, 11-21). However, the Darwin's reports and the influence of the coastal depth on the formation and the evolution of the steep front and the profile of tsunami did not practically discuss. Recently, a mathematical theory of these phenomena was presented in researchspace. auckland. ac. nz/handle/2292/4474. The theory describes the waves which are excited due to nonlinear effects within a shallow coastal zone. The tsunami elevation is described by two components: . Here is the linear (prime) component. It describes the wave coming from the deep ocean. is the nonlinear component. This component may become very important near the coastal line. After that the theory of the shallow waves is used. This theory yields the linear equation for and the weakly

Charles Darwin, the ship's naturalist, came ashore to take the mail coach to Shrewsbury. This was inauspicious end to an epic 5-year voyage around the coast of South America, the results of which were to have a tumultuous impact on scientific thought that has lasted to this day.

  11. The teacher taught? What Charles Darwin owed to John Lubbock (United States)

    Pearn, Alison


    The period around the publication of John Lubbock's Origin of civilisation in 1870 and Charles Darwin's Descent of man and selection in relation to sex the following year is key to a re-evaluation of the relationship between the two men, usually characterized as that of pupil and master. It is in the making of Descent that Lubbock's role as a scientific collaborator is most easily discerned, a role best understood within the social and political context of the time. Lubbock made Darwin—both the man and his science—acceptable and respectable. Less obvious is Darwin's conscious cultivation of Lubbock's patronage in both his private and public life, and Lubbock's equally conscious bestowal, culminating in his role in Darwin's burial in Westminster Abbey.

  12. The curious case of charles darwin and homeopathy. (United States)

    Ullman, Dana


    In 1849, Charles Darwin was so ill that he was unable to work one out of every 3 days, and after having various troubling symptoms for 2-12 years, he wrote to a friend that he was 'going the way of all flesh'. He sought treatment from Dr James Manby Gully, a medical doctor who used water cure and homeopathic medicines. Despite being highly skeptical of these treatments, he experienced a dramatic improvement in his health, though some of his digestive and skin symptoms returned various times in his life. He grew to appreciate water cure, but remained skeptical of homeopathy, even though his own experiments on insectivore plants using what can be described as homeopathic doses of ammonia salts surprised and shocked him with their significant biological effect. Darwin even expressed concern that he should publish these results. Two of Darwin's sons were as incredulous as he was, but their observations confirmed the results of his experiments. Darwin was also known to have read a book on evolution written by a homeopathic physician that Darwin described as similar to his own but 'goes much deeper.'

    Liang, Qian-Jin; Bin, Jie; Zhang, Gen-Fa


    Today, we celebrated 200 years since Charles Darwin, one of the world's most creative and influential thinkers, was born. And there happens to be the 150th anniversary of the publication of his famous book, On the Origin of Species. It is verified that On the Origin of Species is an immortal classic book and is still guiding the study of anagenesis in life science as the development of natural science from then on, and even though most of the ideas in the book are well-known at the present age. In the article, we recall the brilliance and predomination life of Darwin, a great sage with rich scientific achievements, review briefly the novel discoveries and theories after him in the field, and then elucidate the focal points and perspectiveas in near future study of evolution.

    During the preparation of an exhibition in Pavia dedicated to the centennial anniversary of the death of the Italian Pathologist Paolo Mantegazza, a strange cheratinic horn was found at the Museum for the History of the University of Pavia labelled as 'spur of a cock transplanted into an ear of a cow.' After some historical investigation, we found this strange object was at the centre of a scientific correspondence between Mantegazza and Charles Darwin, who made reference to it in his book The Variation of Animals and Plants under Domestication.

  20. Charles Darwin and the evolution of human grammatical systems. (United States)

    Buckingham, Hugh W; Christman, Sarah S


    Charles Darwin's evolutionary theories of animal communication were deeply embedded in a centuries-old model of association psychology, whose prodromes have most often been traced to the writings of Aristotle. His notions of frequency of occurrence of pairings have been passed down through the centuries and were a major ontological feature in the formation of associative connectivity. He focused on the associations of cause and effect, contiguity of sequential occurrence, and similarity among items. Cause and effect were often reduced to another type of contiguity relation, so that Aristotle is most often evoked as the originator of the associative bondings through similarity and contiguity, contiguity being the most powerful and frequent means of association. Contiguity eventually became the overriding mechanism for serial ordering of mental events in both perception and action. The notions of concatenation throughout the association psychology took the form of "trains" of events, both sensory and motor, in such a way that serial ordering came to be viewed as an item-by-item string of locally contiguous events. Modern developments in the mathematics of serial ordering have advanced in sophistication since the early and middle twentieth century, and new computational methods have allowed us to reevaluate the serial concatenative theories of Darwin and the associationists. These new models of serial order permit a closer comparative scrutiny between human and nonhuman. The present study considers Darwin's insistence on a "degree" continuity between human and nonhuman animal serial ordering. We will consider a study of starling birdsongs and whether the serial ordering of those songs provides evidence that they have a syntax that at best differs only in degree and not in kind with the computations of human grammatical structures. We will argue that they, in fact, show no such thing.

  1. Charles Robert Darwin and Alfred Russel Wallace: their dispute over the units of selection. (United States)

    Ruse, Michael


    Charles Darwin and Alfred Russel Wallace independently discovered the mechanism of natural selection for evolutionary change. However, they viewed the working of selection differently. For Darwin, selection was always focused on the benefit for the individual. For Wallace, selection was as much something of benefit for the group as for the individual. This difference is traced to their different background political-economic views, with Darwin in favor of Adam Smith's view of society and Wallace following Robert Owen in being a socialist.

  4. Charles Darwin and the origins of plant evolutionary developmental biology. (United States)

    Friedman, William E; Diggle, Pamela K


    Much has been written of the early history of comparative embryology and its influence on the emergence of an evolutionary developmental perspective. However, this literature, which dates back nearly a century, has been focused on metazoans, without acknowledgment of the contributions of comparative plant morphologists to the creation of a developmental view of biodiversity. We trace the origin of comparative plant developmental morphology from its inception in the eighteenth century works of Wolff and Goethe, through the mid nineteenth century discoveries of the general principles of leaf and floral organ morphogenesis. Much like the stimulus that von Baer provided as a nonevolutionary comparative embryologist to the creation of an evolutionary developmental view of animals, the comparative developmental studies of plant morphologists were the basis for the first articulation of the concept that plant (namely floral) evolution results from successive modifications of ontogeny. Perhaps most surprisingly, we show that the first person to carefully read and internalize the remarkable advances in the understanding of plant morphogenesis in the 1840s and 1850s is none other than Charles Darwin, whose notebooks, correspondence, and (then) unpublished manuscripts clearly demonstrate that he had discovered the developmental basis for the evolutionary transformation of plant form.

    Full Text Available Josef Finsterer,1 John Hayman21Krankenanstalt Rudolfstiftng, Vienna, Austria; 2Department of Pathology, University of Melbourne, Victoria, AustraliaBackground: Charles Darwin (CD, “father of modern biology,” suffered from multisystem illness from early adulthood. The most disabling manifestation was cyclic vomiting syndrome (CVS. This study aims at finding the possible cause of CVS in CD.Methods: A literature search using the PubMed database was carried out, and CD's complaints, as reported in his personal writings and those of his relatives, friends, colleagues, biographers, were compared with various manifestations of mitochondrial disorders (MIDs, known to cause CVS, described in the literature.Results: Organ tissues involved in CD's disease were brain, nerves, muscles, vestibular apparatus, heart, gut, and skin. Cerebral manifestations included episodic headache, visual disturbance, episodic memory loss, periodic paralysis, hysterical crying, panic attacks, and episodes of depression. Manifestations of polyneuropathy included numbness, paresthesias, increased sweating, temperature sensitivity, and arterial hypotension. Muscular manifestations included periods of exhaustion, easy fatigability, myalgia, and muscle twitching. Cardiac manifestations included episodes of palpitations and chest pain. Gastrointestinal manifestations were CVS, dental problems, abnormal seasickness, eructation, belching, and flatulence. Dermatological manifestations included painful lips, dermatitis, eczema, and facial edema. Treatments with beneficial effects to his complaints were rest, relaxation, heat, and hydrotherapy.Conclusion: CVS in CD was most likely due to a multisystem, nonsyndromic MID. This diagnosis is based upon the multisystem nature of his disease, the fact that CVS is most frequently the manifestation of a MID, the family history, the variable phenotypic expression between affected family members, the fact that symptoms were triggered by stress

  7. Bravo Emma! Music in the life and work of Charles Darwin. (United States)

    Derry, J F


    The long-term marital dance of Emma and Charles Darwin was set to the routine beat of an almost daily piano recital. Emma was a proficient pianist, and so a quality instrument was a welcome and appropriate house-warming present for their first marital home in London. That same piano accompanied the Darwins on their move to Downe before being upgraded for a newer model, which is still there, whilst another, cheaper piano may have played in Charles Darwin's work, particularly on earthworms. Whilst he lamented his own lack of musicality, Darwin revelled in his wife's prowess, a capacity that he recognised could be inherited, not least through observation of his own children. The evolution of musicality, he reasoned, was rooted in sexual attraction as a form of communication that preceded language.

  10. The paradoxical advantages and disadvantages of natural selection: the case history of Charles Darwin. (United States)

    Lieb, J


    The biology of natural selection is an enduring mystery, as is the nature of Charles Darwin's chronic illness. Of the theories advanced to explain the latter, Oedipal conflicts and Chagas' disease are preeminent. Hypomania, however, propelled Darwin to the pinnacle of scientific achievement and good health, the depression that followed condemning him to intellectual stagnation, lethargy, impaired memory and concentration, and incapacitating gastrointestinal disorders. Examples of natural selection in humans are much sought after when, ironically, one need look no further than Darwin himself.

  11. 'This excellent observer ...': the correspondence between Charles Darwin and James Crichton-Browne, 1869-75. (United States)

    Pearn, Alison M


    Between May 1869 and December 1875, Charles Darwin exchanged more than 40 letters with James Crichton-Browne, superintendent of the West Riding Pauper Lunatic Asylum, Wakefield, Yorkshire. This paper charts their relationship within the context of Darwin's wider research networks and methods; it analyses the contribution that Crichton-Browne made to the writing of Expression, arguing that the information he provided materially affected Darwin's thesis, and that it was partly the need to assimilate this that led Darwin to publish Expression separately from Descent. The letters help to reconstruct Crichton-Browne's early research interests, and document Darwin's little-explored role as a patron. Both men are revealed within a collaborative scientific network, with each of them at various times a beneficiary or a promoter.

  12. [Charles Darwin and the problem of evolutionary progress]. (United States)

    Iordanskiĭ, N N


    According to Ch. Darwin's evolutionary theory, evolutionary progress (interpreted as morpho-physiological progress or arogenesis in recent terminology) is one of logical results of natural selection. At the same time, natural selection does not hold any factors especially promoting evolutionary progress. Darwin emphasized that the pattern of evolutionary changes depends on organism nature more than on the pattern of environment changes. Arogenesis specificity is determined by organization of rigorous biological systems - integral organisms. Onward progressive development is determined by fundamental features of living organisms: metabolism and homeostasis. The concept of social Darwinism differs fundamentally from Darwin's ideas about the most important role of social instincts in progress of mankind. Competition and selection play secondary role in socio-cultural progress of human society.

    The nineteenth-century Anglican Priest Charles Kingsley (1819-1875) was a significant populariser of Darwin's theory of evolution by natural selection. Kingsley was successful in this regard because he developed such diverse connections throughout his career. In the 1840s he associated with Chartists and radical journalists; in the 1850s and 1860s…

  14. Ferdinand von Mueller's interactions with Charles Darwin and his response to Darwinism. (United States)

    Lucas, A M


    Although Ferdinand Mueller (later von Mueller), Government Botanist of Victoria, opposed Darwin's theories when "On the origin of species" was published, there has been little detailed study of the nature of Mueller's opposition from 1860, when he received a presentation copy of "Origin," to his death in 1896. Analysis of Mueller's correspondence and publications shows that he remained a theist and misunderstood key aspects of Darwin's theory. However, Mueller did come to accept that natural selection could operate within a species, although never accepting it could produce speciation. Despite these differences he retained a cordial relationship with Darwin.

  15. From Charles Darwin's botanical country-house studies to modern plant biology. (United States)

    Kutschera, U; Briggs, W R


    As a student of theology at Cambridge University, Charles Darwin (1809-1882) attended the lectures of the botanist John S. Henslow (1796-1861). This instruction provided the basis for his life-long interest in plants as well as the species question. This was a major reason why in his book On the Origin of Species, which was published 150 years ago, Darwin explained his metaphorical phrase 'struggle for life' with respect to animals and plants. In this article, we review Darwin's botanical work with reference to the following topics: the struggle for existence in the vegetable kingdom with respect to the phytochrome-mediated shade avoidance response; the biology of flowers and Darwin's plant-insect co-evolution hypothesis; climbing plants and the discovery of action potentials; the power of movement in plants and Darwin's conflict with the German plant physiologist Julius Sachs; and light perception by growing grass coleoptiles with reference to the phototropins. Finally, we describe the establishment of the scientific discipline of Plant Biology that took place in the USA 80 years ago, and define this area of research with respect to Darwin's work on botany and the physiology of higher plants.

    Jenkins, Bill


    Evidence for the transformist ideas espoused by Henry H. Cheek (1807-33), a contemporary of Charles Darwin's at the University of Edinburgh, sheds new light on the intellectual environment of Edinburgh in the late 1820s and early 1830s. Cheek was the author of several papers dealing with the transmutation of species influenced by the theories of Etienne Geoffroy Saint-Hilaire (1772-1844), Jean-Baptiste Lamarck (1744-1829) and the Comte de Buffon (1707-88). Some of these were read to student societies, others appeared in the Edinburgh Journal of Natural and Geographical Science, which Cheek edited between 1829 and 1831. His writings give us a valuable window onto some of the transformist theories that were circulating among Darwin's fellow medical students in the late 1820s, to which Darwin would have been exposed during his time in Edinburgh, and for which little other concrete evidence survives.

  18. Charles Darwin's reputation: how it changed during the twentieth-century and how it may change again. (United States)

    Amundson, Ron


    Charles Darwin died in 1882. During the twentieth century his reputation varied through time, as the scientific foundation of evolutionary theory changed. Beginning the century as an intellectual hero, he soon became a virtual footnote as experimental approaches to evolution began to develop. As the Modern Synthesis developed his reputation began to rise again until eventually he was identified as a founding father of the Modern Synthesis itself. In the meantime, developmental approaches to evolution began to challenge certain aspects of the Modern Synthesis. Synthesis authors attempted to refute the relevance of development by methodological arguments, some of them indirectly credited to Darwin. By the end of the century, molecular genetics had given new life to development approaches to evolution, now called evo devo. This must be seen as a refutation of the aforesaid methodological arguments of the Modern Synthesis advocates. By the way, we can also see now how the historiography that credited Darwin with the Synthesis was in error. In conclusion, one more historical revision is suggested. Copyright © 2014 Elsevier Ltd.

  19. Charles Darwin's beagle voyage, fossil vertebrate succession, and "the gradual birth & death of species". (United States)

    Brinkman, Paul D


    The prevailing view among historians of science holds that Charles Darwin became a convinced transmutationist only in the early spring of 1837, after his Beagle collections had been examined by expert British naturalists. With respect to the fossil vertebrate evidence, some historians believe that Darwin was incapable of seeing or understanding the transmutationist implications of his specimens without the help of Richard Owen. There is ample evidence, however, that he clearly recognized the similarities between several of the fossil vertebrates he collected and some of the extant fauna of South America before he returned to Britain. These comparisons, recorded in his correspondence, his diary and his notebooks during the voyage, were instances of a phenomenon that he later called the "law of the succession of types." Moreover, on the Beagle, he was following a geological research agenda outlined in the second volume of Charles Lyell's Principles of Geology, which implies that paleontological data alone could provide an insight into the laws which govern the appearance of new species. Since Darwin claims in On the Origin of Species that fossil vertebrate succession was one of the key lines of evidence that led him to question the fixity of species, it seems certain that he was seriously contemplating transmutation during the Beagle voyage. If so, historians of science need to reconsider both the role of Britain's expert naturalists and the importance of the fossil vertebrate evidence in the development of Darwin's ideas on transmutation.

  20. More on Darwin's illness: comment on the final diagnosis of Charles Darwin. (United States)

    Sheehan, William; Meller, William H; Thurber, Steven


    Without the possibility of confirmatory exhumation, diagnostic inferences about Darwin's illness must remain speculative. A diagnosis of Darwin's aggregate symptoms must account for not only gastrointestinal distress but also his predominant and excessive retching and the conglomerate of other heterogeneous symptoms. We opine that Crohn's disease, posited as the 'final diagnosis', is not sufficient for subsuming his pleiomorphic symptomatology. An additional proposal is outlined that may help to explain his presentation with heterogeneous symptoms. It incorporates constitutional vulnerabilities, psychosomatic influences and Pavlovian conditioning as explanatory variables.

  1. Foundations of a mathematical theory of darwinism. (United States)

    Batty, Charles J K; Crewe, Paul; Grafen, Alan; Gratwick, Richard


    This paper pursues the 'formal darwinism' project of Grafen, whose aim is to construct formal links between dynamics of gene frequencies and optimization programmes, in very abstract settings with general implications for biologically relevant situations. A major outcome is the definition, within wide assumptions, of the ubiquitous but problematic concept of 'fitness'. This paper is the first to present the project for mathematicians. Within the framework of overlapping generations in discrete time and no social interactions, the current model shows links between fitness maximization and gene frequency change in a class-structured population, with individual-level uncertainty but no uncertainty in the class projection operator, where individuals are permitted to observe and condition their behaviour on arbitrary parts of the uncertainty. The results hold with arbitrary numbers of loci and alleles, arbitrary dominance and epistasis, and make no assumptions about linkage, linkage disequilibrium or mating system. An explicit derivation is given of Fisher's Fundamental Theorem of Natural Selection in its full generality.

  2. "A dedicated missionary". Charles Galton Darwin and the new quantum mechanics in Britain (United States)

    Navarro, Jaume

    In this paper I discuss the work on quantum physics and wave mechanics by Charles Galton Darwin, a Cambridge wrangler of the last generation, as a case study to better understand the early reception of quantum physics in Britain. I argue that his proposal in the early 1920s to abandon the strict conservation of energy, as well as his enthusiastic embracement of wave mechanics at the end of the decade, can be easily understood by tracing his ontological and epistemological commitments to his early training in the Cambridge Mathematical Tripos. I also suggest that Darwin's work cannot be neglected in a study of quantum physics in Britain, since he was one of very few fellows of the Royal Society able to judge and explain quantum physics and quantum mechanics.

  3. Exploring the nature of science through courage and purpose: a case study of Charles Darwin's way of knowing. (United States)

    Cohen, Joel I


    In 1836, Charles Darwin returned to England with finches classified and seemingly showing little resemblance. However, subsequent examination by John Gould revealed 13 closely related species endemic to the Galápagos Islands. Despite initial confusion, and Darwin's overlooking to label these birds by island, some 100 years later they had become evolution's icon. The same could be said of Darwin's education and scientific pursuits, beginning in a rough, trial and error manner, lacking direction, but eventually benefitting from an unexpected opportunity that would lead to his theory of natural selection. This case study examines Darwin's way of learning and the reserve of courage and perseverance that he would need to see his treatise on evolution and natural selection published. To do this, themes from studying the "Nature of Science" are used to examine how Darwin's "way of knowing" advanced before and after his voyage upon HMS Beagle. Five themes from the "Nature of Science" were selected to illustrate Darwin's struggles and triumph: creating scientific knowledge is a human endeavor, such knowledge can explain an order and consistency in natural systems, knowledge comes from a scientist's way of knowing, is open to revision, and based on empirical evidence. The "Nature of Science" as applied to Charles Darwin is explored through the three above mentioned themes identified by the Next Generation Science Standards. Together, the themes help explain Darwin's way of knowing, from boyhood to manhood. This explanation helps humanize Darwin, allows students to see how he arrived at his theories, how the time taken to do so wore on his health and safety, and the risk Darwin had to weigh from their eventual publication. Each theme ends with a summary and related extension questions to draw students into the case, and facilitate inquiry. They relate Darwin's way of learning from the 1800s and his commitment to see his work published, to the learning environment of

  4. The 'root-brain' hypothesis of Charles and Francis Darwin: Revival after more than 125 years. (United States)

    Baluska, Frantisek; Mancuso, Stefano; Volkmann, Dieter; Barlow, Peter W


    This year celebrates the 200(th) aniversary of the birth of Charles Darwin, best known for his theory of evolution summarized in On the Origin of Species. Less well known is that, in the second half of his life, Darwin's major scientific focus turned towards plants. He wrote several books on plants, the next-to-last of which, The Power of Movement of Plants, published together with his son Francis, opened plants to a new view. Here we amplify the final sentence of this book in which the Darwins proposed that: "It is hardly an exaggeration to say that the tip of the radicle thus endowed [with sensitivity] and having the power of directing the movements of the adjoining parts, acts like the brain of one of the lower animals; the brain being seated within the anterior end of the body, receiving impressions from the sense-organs, and directing the several movements." This sentence conveys two important messages: first, that the root apex may be considered to be a 'brain-like' organ endowed with a sensitivity which controls its navigation through soil; second, that the root apex represents the anterior end of the plant body. In this article, we discuss both these statements.

  5. Charles Darwin's Origin of Species, directional selection, and the evolutionary sciences today. (United States)

    Kutschera, Ulrich


    The book On the Origin of Species, published in November 1859, is an "abstract" without references, compiled by Charles Darwin from a much longer manuscript entitled "Natural Selection." Here, I summarize the five theories that can be extracted from Darwin's monograph, explain the true meaning of the phrase "struggle for life" (i.e., competition and cooperation), and outline Darwin's original concept of natural selection in populations of animals and plants. Since neither Darwin nor Alfred R. Wallace distinguished between stabilizing and directional natural selection, the popular argument that "selection only eliminates but is not creative" is still alive today. However, I document that August Weismann (Die Bedeutung der sexuellen Fortpflanzung für die Selektions-Theorie. Gustav Fischer-Verlag, Jena, 1886) and Ivan Schmalhausen (Factors of evolution. The theory of stabilizing selection. The Blackiston Company, Philadelphia, 1949) provided precise definitions for directional (dynamic) selection in nature and illustrate this "Weismann-Schmalhausen principle" with respect to the evolutionary development of novel phenotypes. Then, the modern (synthetic) theory of biological evolution that is based on the work of Theodosius Dobzhansky (Genetics and the origin of species. Columbia University Press, New York, 1937) and others, and the expanded version of this system of theories, are outlined. Finally, I document that symbiogenesis (i.e., primary endosymbiosis, a process that gave rise to the first eukaryotic cells), ongoing directional natural selection, and the dynamic Earth (plate tectonics, i.e., geological events that both created and destroyed terrestrial and aquatic habitats) were the key processes responsible for the documented macroevolutionary patterns in all five kingdoms of life. Since the evolutionary development of the earliest archaic bacteria more than 3,500 mya, the biosphere of our dynamic planet has been dominated by prokaryotic microbes. Eubacteria

  6. Darwinian hydrology: can the methodology Charles Darwin pioneered help hydrologic science? (United States)

    Harman, C.; Troch, P. A.


    There have been repeated calls for a Darwinian approach to hydrologic science or for a synthesis of Darwinian and Newtonian approaches, to deepen understanding the hydrologic system in the larger landscape context, and so develop a better basis for predictions now and in an uncertain future. But what exactly makes a Darwinian approach to hydrology "Darwinian"? While there have now been a number of discussions of Darwinian approaches, many referencing Harte (2002), the term is potentially a source of confusion while its connections to Darwin remain allusive rather than explicit. Here we discuss the methods that Charles Darwin pioneered to understand a variety of complex systems in terms of their historical processes of change. We suggest that the Darwinian approach to hydrology follows his lead by focusing attention on the patterns of variation in populations, seeking hypotheses that explain these patterns in terms of the mechanisms and conditions that determine their historical development, using deduction and modeling to derive consequent hypotheses that follow from a proposed explanation, and critically testing these hypotheses against new observations. It is not sufficient to catalogue the patterns or predict them statistically. Nor is it sufficient for the explanations to amount to a "just-so" story not subject to critical analysis. Darwin's theories linked present-day variation to mechanisms that operated over history, and could be independently test and falsified by comparing new observations to the predictions of corollary hypotheses they generated. With a Darwinian framework in mind it is easy to see that a great deal of hydrologic research has already been done that contributes to a Darwinian hydrology - whether deliberately or not. The various heuristic methods that Darwin used to develop explanatory theories - extrapolating mechanisms, space for time substitution, and looking for signatures of history - have direct application in hydrologic science. Some

  7. Studying phenotypic evolution in domestic animals: a walk in the footsteps of Charles Darwin. (United States)

    Andersson, L


    Charles Darwin used domesticated plants and animals as proof of principle for his theory on phenotypic evolution by means of natural selection. Inspired by Darwin's work, we developed an intercross between the wild boar and domestic pigs to study the genetic basis for phenotypic changes during domestication. The difference in coat color is controlled by two major loci. Dominant white color is due to two consecutive mutations in the KIT gene: a 450-kb duplication and a splice mutation. Black spotting is caused by the combined effect of two mutations in MC1R: a missense mutation for dominant black color and a 2-bp insertion leading to a frameshift. A major discovery made using this pedigree is the identification of a single-nucleotide substitution in intron 3 of the gene for insulin-like growth factor 2 (IGF2) that is underlying a quantitative trait locus affecting muscle growth, size of the heart, and fat deposition. The mutation disrupts the interaction with a repressor and leads to threefold increased IGF2 expression in postnatal muscle. In a recent study, we have identified the IGF2 repressor, and this previously unknown protein, named ZBED6, is specific for placental mammals and derived from a domesticated DNA transposon.

  10. Evolution in a fully constituted world: Charles Darwin's debts towards a static world in the Origin of Species (1859). (United States)

    Delisle, Richard G


    The Transformist Revolution was a long intellectual quest that has expanded from the 18th century to today. One area of inquiry after another has confronted the necessity of recasting its object of study under an evolutionary view: human history, geology, biology, astronomy, etc. No single scholar fully managed to make the transition from a static worldview to an evolutionary one during his or her own lifetime; Charles Darwin is no exception. Many versions of evolutionism were proposed during this revolution, versions offering all sorts of compromises between old and new views. Not sufficiently acknowledged in the historiography is the profoundness of Darwin's debts towards the old static view. As a dual child of the Scientific Revolution and natural theology, Darwin inherited key concepts such as stability, completeness, timelessness, unity, permanence, and uniformity. Darwin took these concepts into consideration while erecting his theory of biological evolution. Unsurprisingly, this theory was ill-equipped to embrace the directionality, historicity, and novelty that came along with a new evolutionary world. This paper analyses a fundamental idea at the heart of Darwin's Origins of Species (1859) inherited from a static, stable, and machine-like conception of the world: the notion of a fully constituted world. Although in principle antithetical to the very idea of evolution itself, Darwin found a way to 'loosen up' this notion so as to retain it in a way that allows for some kind of evolutionary change.

All CTD data is compared with reversing thermometer observations, and with determinations of salinity and dissolved oxygen derived from samples. (author)

  12. "My appointment received the sanction of the Admiralty": why Charles Darwin really was the naturalist on HMS Beagle. (United States)

    van Wyhe, John


    For decades historians of science and science writers in general have maintained that Charles Darwin was not the 'naturalist' or 'official naturalist' during the 1831-1836 surveying voyage of HMS Beagle but instead Captain Robert FitzRoy's 'companion', 'gentleman companion' or 'dining companion'. That is, Darwin was primarily the captain's social companion and only secondarily and unofficially naturalist. Instead, it is usually maintained, the ship's surgeon Robert McCormick was the official naturalist because this was the default or official practice at the time. Although these views have been repeated in countless accounts of Darwin's life, this essay aims to show that they are incorrect. Copyright © 2013 Elsevier Ltd. All rights reserved.

  13. When sleep-related hypermotor epilepsy (SHE) met Charles Darwin and Francis Galton. (United States)

    Parrino, Liborio; Pavesi, Giovanni


    Sleep-related hypermotor epilepsy (SHE) is characterized by short-lasting seizures patterned by repetitive and stereotyped motor events in the same person. In autosomal dominant SHE, genetic factors play a well-known key role. In The Expression of Emotions in Man and Animals, Charles Darwin quotes a plausible example of SHE illustrated by his cousin Sir Francis Galton: "the gentleman…lay fast asleep on his back in bed, raising his right arm slowly in front of his face, up to his forehead, and then dropping it with a jerk, so that the wrist fell heavily on the bridge of his nose. The trick did not occur every night, but occasionally, and was independent of any ascertained cause. Sometimes it was repeated incessantly for an hour or more." Similar manifestations during sleep occurred also in the patient's son and granddaughter, suggesting an autosomal inheritance without sex relationship. Differential diagnosis with REM behavior disorder and other parasomnias is discussed. To our knowledge, this could be the first description of a stereotyped SHE pattern with genetic transmission. © 2017 American Academy of Neurology.

    Full Text Available Este artigo visa à evocação da memória do grande naturalista e cientista britânico Charles Darwin no bicentenário do seu nascimento. A melhor maneira de evocar sua memória é trazer à reflexão dos leitores as ideias de suas três obras maiores: A origem das espécies (1859, A descendência do homem (1871 e A expressão das emoções no homem e nos animais (1872. Após apresentar a importância e a oportunidade de Darwin no debate contemporâneo, o texto inicia com uma rápida referência aos antecedentes históricos da "teoria da evolução" e às reações que ela produz. Na sequência, a obra de Darwin é situada no contexto histórico da sua época. Apresenta-se também um breve histórico das três obras maiores e uma análise das suas principais ideias. Conclui-se o texto com uma indicação sumária de algumas questões que as ideias de Darwin colocam à ciência contemporânea e, em especial, à reflexão no campo da Educação.This paper evokes the memory of the British naturalist and scientist, Charles Darwin on his 200th birthday. The best way to do so is to invite our readers to reflect on some ideas of three books of his: The origin of species (1859, Descent of man (1871 and The expression of emotions in man and animals (1872. After presenting the importance and appropriateness of Darwin in the contemporaneous debate, the text rapidly explores the historical precedents of the so called "theory of evolution" and the reactions to it. It then situates Darwin's works in its historical context and presents a brief history of these three books and an analysis of their main ideas. As a conclusion, it summarizes how Darwin's ideas question contemporary science and, more particularly, the reflection in the field of education.

  15. Charles Darwin's Origin of Species, directional selection, and the evolutionary sciences today (United States)

    Kutschera, Ulrich


    The book On the Origin of Species, published in November 1859, is an “abstract” without references, compiled by Charles Darwin from a much longer manuscript entitled “Natural Selection.” Here, I summarize the five theories that can be extracted from Darwin’s monograph, explain the true meaning of the phrase “struggle for life” (i.e., competition and cooperation), and outline Darwin’s original concept of natural selection in populations of animals and plants. Since neither Darwin nor Alfred R. Wallace distinguished between stabilizing and directional natural selection, the popular argument that “selection only eliminates but is not creative” is still alive today. However, I document that August Weismann ( Die Bedeutung der sexuellen Fortpflanzung für die Selektions-Theorie. Gustav Fischer-Verlag, Jena, 1886) and Ivan Schmalhausen ( Factors of evolution. The theory of stabilizing selection. The Blackiston Company, Philadelphia, 1949) provided precise definitions for directional (dynamic) selection in nature and illustrate this “Weismann-Schmalhausen principle” with respect to the evolutionary development of novel phenotypes. Then, the modern (synthetic) theory of biological evolution that is based on the work of Theodosius Dobzhansky ( Genetics and the origin of species. Columbia University Press, New York, 1937) and others, and the expanded version of this system of theories, are outlined. Finally, I document that symbiogenesis (i.e., primary endosymbiosis, a process that gave rise to the first eukaryotic cells), ongoing directional natural selection, and the dynamic Earth (plate tectonics, i.e., geological events that both created and destroyed terrestrial and aquatic habitats) were the key processes responsible for the documented macroevolutionary patterns in all five kingdoms of life. Since the evolutionary development of the earliest archaic bacteria more than 3,500 mya, the biosphere of our dynamic planet has been dominated by

  17. Charles Darwin, Richard Owen, and Natural Selection: A Question of Priority. (United States)

    Johnson, Curtis N


    No single author presented Darwin with a more difficult question about his priority in discovering natural selection than the British comparative anatomist and paleontologist Richard Owen. Owen was arguably the most influential biologist in Great Britain in Darwin's time. Darwin wanted his approbation for what he believed to be his own theory of natural selection. Unfortunately for Darwin, when Owen first commented in publication about Darwin's theory of descent he was openly hostile (Edinb. Rev. vol. 111, Article VIII, 1860, pp. 487-533, anonymous). Darwin was taken off-guard. In private meetings and correspondence prior to 1860 Owen had been nothing but polite and friendly, even helping Darwin in cataloguing and analyzing Darwin's zoological specimens from the Beagle voyage. Every early indication predicted a life-long friendship and collaboration. But that was not to be. Owen followed his slashing review with a mounting campaign in the 1860s to denounce and discredit both Darwin and his small but ascendant circle of friends and supporters. But that was not enough for Owen. Starting in 1866, perhaps by now realizing Darwin had landed the big fish, Owen launched a new campaign, to claim the discovery of "Darwin's theory" for himself. Darwin naturally fought back, mainly in the "Historical Sketch" that he prefaced to Origin starting in 1861. But when we peel back the layers of personal animus and escalating vituperation we discover in fact their quarrel was generated more by mutual misunderstanding than scientific disagreement. The battle ended only when Darwin finally penetrated to the crux of the matter and put an end to the rivalry in 1872, in the final version of the Sketch.

  18. Charles Darwin and psychology at the bicentennial and sesquicentennial: an introduction. (United States)

    Dewsbury, Donald A


    This article provides an introduction to the special issue on Darwin and psychology at the bicentennial of his birth and the sesquicentennial of his publication of On the Origin of Species. His core contributions, as viewed today, were his theory of natural selection, his naturalistic philosophy, and his mass of evidence for evolutionary change. A brief summary of Darwin's life is also presented. Among Darwin's contributions to psychology were his demonstration of the continuity of species, a model for the study of instinct, a book on the expression of the emotions, and a baby biography. Previous celebrations of Darwin and the changing perceptions of his work since its publication are described. Darwin's theory remains an important part of psychology. 2009 APA, all rights reserved

  19. Explosive Volcanic Activity at Extreme Depths: Evidence from the Charles Darwin Volcanic Field, Cape Verdes (United States)

    Kwasnitschka, T.; Devey, C. W.; Hansteen, T. H.; Freundt, A.; Kutterolf, S.


    Volcanic eruptions on the deep sea floor have traditionally been assumed to be non-explosive as the high-pressure environment should greatly inhibit steam-driven explosions. Nevertheless, occasional evidence both from (generally slow-) spreading axes and intraplate seamounts has hinted at explosive activity at large water depths. Here we present evidence from a submarine field of volcanic cones and pit craters called Charles Darwin Volcanic Field located at about 3600 m depth on the lower southwestern slope of the Cape Verdean Island of Santo Antão. We examined two of these submarine volcanic edifices (Tambor and Kolá), each featuring a pit crater of 1 km diameter, using photogrammetric reconstructions derived from ROV-based imaging followed by 3D quantification using a novel remote sensing workflow, aided by sampling. The measured and calculated parameters of physical volcanology derived from the 3D model allow us, for the first time, to make quantitative statements about volcanic processes on the deep seafloor similar to those generated from land-based field observations. Tambor cone, which is 2500 m wide and 250 m high, consists of dense, probably monogenetic medium to coarse-grained volcaniclastic and pyroclastic rocks that are highly fragmented, probably as a result of thermal and viscous granulation upon contact with seawater during several consecutive cycles of activity. Tangential joints in the outcrops indicate subsidence of the crater floor after primary emplacement. Kolá crater, which is 1000 m wide and 160 m deep, appears to have been excavated in the surrounding seafloor and shows stepwise sagging features interpreted as ring fractures on the inner flanks. Lithologically, it is made up of a complicated succession of highly fragmented deposits, including spheroidal juvenile lapilli, likely formed by spray granulation. It resembles a maar-type deposit found on land. The eruption apparently entrained blocks of MORB-type gabbroic country rocks with

  20. 3D-Reconstruction of recent volcanic activity from ROV-video, Charles Darwin Seamounts, Cape Verdes (United States)

    Kwasnitschka, T.; Hansteen, T. H.; Kutterolf, S.; Freundt, A.; Devey, C. W.


    As well as providing well-localized samples, Remotely Operated Vehicles (ROVs) produce huge quantities of visual data whose potential for geological data mining has seldom if ever been fully realized. We present a new workflow to derive essential results of field geology such as quantitative stratigraphy and tectonic surveying from ROV-based photo and video material. We demonstrate the procedure on the Charles Darwin Seamounts, a field of small hot spot volcanoes recently identified at a depth of ca. 3500m southwest of the island of Santo Antao in the Cape Verdes. The Charles Darwin Seamounts feature a wide spectrum of volcanic edifices with forms suggestive of scoria cones, lava domes, tuff rings and maar-type depressions, all of comparable dimensions. These forms, coupled with the highly fragmented volcaniclastic samples recovered by dredging, motivated surveying parts of some edifices down to centimeter scale. ROV-based surveys yielded volcaniclastic samples of key structures linked by extensive coverage of stereoscopic photographs and high-resolution video. Based upon the latter, we present our workflow to derive three-dimensional models of outcrops from a single-camera video sequence, allowing quantitative measurements of fault orientation, bedding structure, grain size distribution and photo mosaicking within a geo-referenced framework. With this information we can identify episodes of repetitive eruptive activity at individual volcanic centers and see changes in eruptive style over time, which, despite their proximity to each other, is highly variable.

  1. Die ‘vergroening’ van die Christelike godsdiens: Charles Darwin, Pierre Teilhard de Chardin en Lloyd Geering

    Directory of Open Access Journals (Sweden)

    Izak J.J. (Sakkie Spangenberg


    Full Text Available The greening of Christianity: Charles Darwin, Pierre Teilhard de Chardin and Lloyd Geering. Since the time of Charles Darwin, evolutionary biology challenged the metanarrative of Christianity which can be summarised as Fall-Redemption-Judgement. Pierre Teilhard de Chardin tried to circumvent these challenges by integrating the traditional Christian doctrines with evolutionary biology. However, he did not succeed since the Catholic Church, time and again, vetoed his theological publications. A number of Protestant theologians promoted his views but even they could not convince ordinary Christians to accept his views. These were too esoteric for Christians. Most of them were convinced that the acceptance of the theory of evolution will eventually undermine their faith. In recent years Lloyd Geering argued a case for the creation of a new narrative in which the Big Bang and the theory of evolution do play a role. He calls it the ‘Greening of Christianity’. This article discusses the metanarrative of Christianity and the challenges the theory of evolution presents before it assesses the views of Pierre Teilhard de Chardin and Lloyd Geering.

  2. Correspondence of Charles Darwin on James Torbitt's project to breed blight-resistance potatoes. (United States)

    DeArce, M


    The most prolific of Darwin's correspondents from Ireland was James Torbitt, an enterprising grocer and wine merchant of 58 North Street, Belfast. Between February 1876 and March 1882, 141 letters were exchanged on the feasibility and ways of supporting one of Torbitt's commercial projects, the large-scale production and distribution of true potato seeds (Solan um tuberosum) to produce plants resistant to the late blight fungus Phytophthora infestans, the cause of repeated potato crop failures and thus the Irish famines in the nineteenth century. Ninety-three of these letters were exchanged between Torbitt and Darwin, and 48 between Darwin and third parties, seeking or offering help and advice on the project. Torbitt's project required selecting the small proportion of plants in an infested field that survived the infection, and using those as parents to produce seeds. This was a direct application of Darwin's principle of selection. Darwin cautiously lobbied high-ranking civil servants in London to obtain government funding for the project, and also provided his own personal financial support to Torbit.

  3. There is grandeur in this view of Newton: Charles Darwin, Isaac Newton and Victorian conceptions of scientific virtue. (United States)

    Bellon, Richard


    For Victorian men of science, the scientific revolution of the seventeenth century represented a moral awakening. Great theoretical triumphs of inductive science flowed directly from a philosophical spirit that embraced the virtues of self-discipline, courage, patience and humility. Isaac Newton exemplified this union of moral and intellectual excellence. This, at least, was the story crafted by scientific leaders like David Brewster, Thomas Chalmers, John Herschel, Adam Sedgwick and William Whewell. Not everyone accepted this reading of history. Evangelicals who decried the 'materialism' of mainstream science assigned a different meaning to Newton's legacy on behalf of their 'scriptural' alternative. High-church critics of science like John Henry Newman, on the other hand, denied that Newton's secular achievements carried any moral significance at all. These debates over Newtonian standards of philosophical behavior had a decisive influence on Charles Darwin as he developed his theory of evolution by natural selection.

  4. Charles Darwin in modern epidemiology and public health: the celebration continues. (United States)

    Hanage, W P


    2009 was Darwin year; his familiar bearded face peered out from a great radiation of TV series, book covers and even a feature film. The reasons for this were his bicentennial and the 150th anniversary of the publication of the Origin of Species. However, there is no reason the celebrations should cease with the turn of the New Year.

  5. The many lives of Charles Darwin: early biographies and the definitive evolutionist. (United States)

    Lightman, Bernard


    This article focuses on the early book-length biographies of Darwin published from his death in 1882 up to 1900. By making 1900 the cutoff point I can examine the biographies produced when the iconic figure was not yet set in stone, and before the rediscovery of Mendel's work in the early twentieth century and the anniversary celebrations of 1909 changed the way in which Darwin was regarded. Darwin's biographers dealt with three major themes. First, several biographers emphasized his scientific abilities, in particular his powers of observation and his prowess in conducting experiments. Second, many biographers discussed his character, a key issue in determining whether or not he could be trusted as a scientific guide. Finally, his scientific theories and religious beliefs, and how they related to the evolutionary controversy, formed a topic taken up by most biographers. By focusing on these three themes, the biographies published before 1900 were important in shaping the image of Darwin that was forming in American and British culture.

  6. Charles Darwin's emotional expression "experiment" and his contribution to modern neuropharmacology. (United States)

    Snyder, Peter J; Kaufman, Rebecca; Harrison, John; Maruff, Paul


    In the late 1860s and early 1870s, Darwin had corresponded with the French physician and physiologist, G. B. A. Duchenne, regarding Duchenne's experimental manipulation of human facial expression of emotion, by applying Galvanic electrical stimulation directly to facial muscles. Duchenne had produced a set of over 60 photographic plates to illustrate his view that there are different muscles in the human face that are separately responsible for each individual emotion. Darwin studied this material very carefully and he received permission from Duchenne in 1871 to reproduce several of these images in The Expression of the Emotions in Man and Animals (1872). Darwin had doubted Duchenne's view that there were individual muscle groups that mediate the expression of dozens of separable emotions, and he wondered whether there might instead be a fewer set of core emotions that are expressed with great stability worldwide and across cultures. Prompted by his doubts regarding the veracity of Duchenne's model, Darwin conducted what may have been the first-ever single-blind study of the recognition of human facial expression of emotion. This single experiment was a little-known forerunner for an entire modern field of study with contemporary clinical relevance. Moreover, his specific question about cross-cultural recognition of the cardinal emotions in faces is a topic that is being actively studied (in the twenty-first century) with the hope of developing novel biomarkers to aid the discovery of new therapies for the treatment of schizophrenia, autism, and other neuropsychiatric diseases.

  7. Sympathetic science: Charles Darwin, Joseph Hooker, and the passions of Victorian naturalists. (United States)

    Endersby, Jim


    This essay examines the complex tangle of emotional and scientific attachments that linked Darwin and botanist Joseph Dalton Hooker. Analyzing their roles as husbands, fathers, and novel readers demonstrates that possessing and expressing sympathy was as important for Victorian naturalists as it was for Victorian husbands. Sympathy was a scientific skill that Victorian naturalists regarded as necessary to fully understand the living world; although sympathy became increasingly gendered as feminine over the course of the century, its importance to male naturalists requires us to rethink the ways gender roles were negotiated in Victorian Britain. Botany was, for men like Darwin and Hooker, an acceptably masculine pursuit that nevertheless allowed--and even required--them to be sensitive and sympathetic.

  12. Responding to soil erosion in Spain: from Charles Darwin to John Thornes

    Energy Technology Data Exchange (ETDEWEB)

    Imeson, A.


    During a discussion of the European Soil Framework Directive last year, John Thornes commented on the paradox that although there was much scientific progress in understanding desertification and erosion, relatively few scientists were responding to the opportunity of responding. Most scientists passively accept the situation of little effective soil and land governance in Europe John Thornes thought that one difficulty is that researchers work in isolation and assume someone else is caring about the big picture. those looking after the big picture are in fact managing soil and land from the perspectives of things such as rural poverty reduction and food security and interventions for farmer's. These are in themselves excellent points of view but they need to be balanced and limited by guidelines provided from the perspective of the requirements of medium and long term soil conservation and protection. There is an absolute need for a European Soil Conservation service as there is in the United States and china. As Darwin said when looking at the increase in population of animals in South America: There must be something limiting growth. Now the only thing limiting growth in many places might be erosion and desertification. (Author) 13 refs.

  14. Darwin's legacy (United States)

    Susskind, Leonard


    Charles Darwin was no theoretical physicist, and I am no biologist. Yet, as a theoretical physicist, I have found much to think about in Darwin's legacy - and in that of his fellow naturalist Alfred Russell Wallace. Darwin's style of science is not usually thought of as theoretical and certainly not mathematical: he was a careful observer of nature, kept copious notes, contributed to zoological collections; and eventually from his vast repertoire of observation deduced the idea of natural selection as the origin of species. The value of theorizing is often dismissed in the biological sciences as less important than observation; and Darwin was the master observer.

  15. Beagle I and II Voyages: Charles Darwin's rocks and the quest for Mars rock; the Open University's virtual microscope has both (United States)

    Schwenzer, S. P.; Tindle, A. G.; Anand, M.; Gibson, E. K.; Pearson, V. K.; Pemberton, D.; Pillinger, C.; Smith, C. L.; Whalley, P.; Kelley, S. P.


    Exploration is in itself a fascinating subject, and a strong draw to engaging the public in understanding science. Nearly two hundred years ago Charles Darwin took part in an exploration of the Earth, and more recently we have begun to explore the solar system and in particular the surface of Mars. The engagement is made easier if an element of exploration is involved in the public engagement, using modern internet and even mobile technologies. The Open University combines all those aspects in a series of virtual microscopes for Earth science that are freely available on the web, installed in museums, or built into its teaching material. The basis of the virtual microscope is a mosaic of several hundred microscopic images of each thin section taken in plane polarised light, between crossed polars and in reflected light, which are then assembled into three high resolution images. Rotation movies for selected points in the thin section illustrate changing optical properties such as birefringence. The user is able to pan and zoom around to explore the section, studying the mineralogy and rock texture, and view the rotation movies linked to points in the section to see the changing birefringence colours. We have created several collections of terrestrial rocks, mainly for teaching purposes, and outreach directly linked to exploration: Charles Darwin returned from the Voyage of the Beagle with a large variety of rock samples, and although thin sections were not being made at that time, they were created from his rocks in the late 19th century. The historic material is part of the "Darwin the Geologist" exhibition at the Sedgwick Museum in Cambridge. Our Darwin virtual microscope includes hand specimen illustrations and thin sections together with documentation and an interactive map allow internet users and museum visitors alike to have a close look at Darwin's rocks and study the petrology of them. Charles Darwin explored distant horizons on Earth in the 19th century

  16. The uncertain foundation of neo-Darwinism: metaphysical and epistemological pluralism in the evolutionary synthesis. (United States)

    Delisle, Richard G


    The Evolutionary Synthesis is often seen as a unification process in evolutionary biology, one which provided this research area with a solid common theoretical foundation. As such, neo-Darwinism is believed to constitute from this time onward a single, coherent, and unified movement offering research guidelines for investigations. While this may be true if evolutionary biology is solely understood as centred around evolutionary mechanisms, an entirely different picture emerges once other aspects of the founding neo-Darwinists' views are taken into consideration, aspects potentially relevant to the elaboration of an evolutionary worldview: the tree of life, the ontological distinctions of the main cosmic entities (inert matter, biological organisms, mind), the inherent properties of self-organizing matter, evolutionary ethics, and so on. Profound tensions and inconsistencies are immediately revealed in the neo-Darwinian movement once this broader perspective is adopted. This pluralism is such that it is possible to identify at least three distinct and quasi-incommensurable epistemological/metaphysical frameworks as providing a proper foundation for neo-Darwinism. The analysis of the views of Theodosius Dobzhansky, Bernhard Rensch, and Ernst Mayr will illustrate this untenable pluralism, one which requires us to conceive of the neo-Darwinian research agenda as being conducted in more than one research programme or research tradition at the same time.

  18. Charles Darwin's Observations on the Behaviour of Earthworms and the Evolutionary History of a Giant Endemic Species from Germany, Lumbricus badensis (Oligochaeta: Lumbricidae)

    International Nuclear Information System (INIS)

    Kutschera, U.; Elliott, M.


    The British naturalist Charles Darwin (1809/1882) began and ended his almost 45-year-long career with observations, experiments, and theories related to earthworms. About six months before his death, Darwin published his book on The Formation of Vegetable Mould, through the Actions of Worms, With Observations on their Habits (1881). Here we describe the origin, content, and impact of Darwin's last publication on earthworms (subclass Oligochaeta, family Lumbricidae) and the role of these annelids as global ecosystem re workers (concept of bioturbation). In addition, we summarize our current knowledge on the reproductive behaviour of the common European species Lumbricus terrestris. In the second part of our account we describe the biology and evolution of the giant endemic species L. badensis from south western Germany with reference to the principle of niche construction. Bio geographic studies have shown that the last common ancestor of L. badensis, and the much smaller sister-taxon, the Atlantic-Mediterranean L. friendi, lived less than 10000 years ago. Allopatric speciation occurred via geographically isolated founder populations that were separated by the river Rhine so that today two earthworm species exist in different areas.

    Many people worry that the theory of evolution that Charles Darwin gave in his Origin of Species is now dated and no longer part of modern science. This essay challenges this claim, arguing that the central core of the Origin is as vital today as it ever was, although naturally the science keeps moving on.

  7. Darwin endures, despite disparagement. (United States)

    Van Den Berg, Hugo A


    Evolution lies at the heart of the life sciences, and Charles Darwin is a towering historical figure within evolutionary science. One testimony to his lasting influence is that declaring Darwin to have been wrong all along remains a provocative way to command attention. The present paper discusses various strands of 'Darwin was wrong' partisans and their divergent views and motives: some are looking to Darwin to justify or condemn the political ideologies that they support or reject; others are concerned with the corrupting influence that the bleak cosmic outlook of evolution is deemed to exert on the moral or religious rectitude of impressionable minds, or regard Darwinism as a direct assault on religion; philosophers question the very coherence of the entire enterprise; and certain biologists aspire to go down in history as even greater than Darwin. It is sobering to reflect that this diverse group is united only by their poor grasp of Darwin's theory of natural selection.

  8. Darwin as a student of behavior. (United States)

    Thierry, Bernard


    In The Expression of the Emotions, Charles Darwin documents evolutionary continuity between animals and humans, emphasizing the universality of expressions in man. Most of the book addresses human behavior, and its influence on the study of animal behavior has been weak. The issue of natural selection is remarkably absent from this book, which relies on the inheritance of acquired characters rather than on a genuine Darwinian logic. Yet Konrad Lorenz considered Darwin to be a forerunner of behavioral biology. The reason was to be found in The Descent of Man and chapter VIII of The Origin of Species, where Darwin provides an explanation of behavior through selection, stating that the same mechanisms explaining morphological changes also account for gradual improvements in instincts. He assessed the accuracy of his evolutionary theory by directly studying animal behavior, hence laying the foundations of behavioral research for the next century. 2009 Académie des sciences.

  9. Darwin the scientist. (United States)

    Browne, J


    Charles Darwin's experimental investigations show him to have been a superb practical researcher. These skills are often underestimated today when assessing Darwin's achievement in the Origin of Species and his other books. Supported by a private income, he turned his house and gardens into a Victorian equivalent of a modern research station. Darwin participated actively in the exchange of scientific information via letters and much of his research was also carried out through correspondence. Although this research was relatively small scale in practice, it was large scale in intellectual scope. Darwin felt he had a strong desire to understand or explain whatever he observed.

  11. "Dancing on eggs": Charles H. Bynum, racial politics, and the National Foundation for Infantile Paralysis, 1938-1954. (United States)

    Mawdsley, Stephen E


    In 1938, President Franklin D. Roosevelt and his law partner Basil O'Connor formed the National Foundation for Infantile Paralysis (NFIP) to battle the viral disease poliomyelitis. Although the NFIP program was purported to be available for all Americans irrespective of "race, creed, or color," officials encountered numerous difficulties upholding this pledge in a nation divided by race. In 1944, NFIP officials hired educator Charles H. Bynum to head a new department of "Negro Activities." Between 1944 and 1954, Bynum negotiated the NFIP bureaucracy to educate officials and influence their national health policy. As part of the NFIP team, he helped increase interracial fund-raising in the March of Dimes, improve polio treatment for black Americans, and further the civil rights movement.

  12. In praise of Darwin (United States)


    Charles Darwin, who was born 200 years ago, is rightly being celebrated as the founding father of modern biology with a series of events around the world this year. Just as Einstein revolutionized physics, so Darwin changed our understanding of life. He came to realize that "natural selection" could account for the huge diversity of life, with more-efficient groups-arising from random variation-always replacing less-efficient groups in a particular environment as a result of competition. After publishing his seminal book On the Origin of Species in 1859-exactly 150 years ago-Darwin, like Einstein, became the most noted scientist of his time.

    This article analyses the Danish 1909 celebrations of the centenary of Charles Darwin's birth on 12 February 1809. I argue that the 1909 meetings, lectures and publications devoted to Darwin and his theory of evolution by natural selection can be characterised by ambivalence: On the one hand...... activities, focusing primarily on celebratory articles carried in widely circulated magazines and newspapers. I identify three types of interpretations of Darwin's ideas which I characterise as ‘radical', ‘evangelical' and ‘safe' science. These different positions were closely linked to the political...... and cultural divisions of the periodical press. Moreover, my analysis of the popular press offers a solid basis for asserting that to most people Darwinism was associated with human evolution, primarily the relationship between man and apes, while more sophisticated discussions about the crisis of Darwinism...

  18. Darwin: German mystic or French rationalist? (United States)

    Ghiselin, Michael T


    The notion that Charles Darwin embraced the German Romantic tradition seems plausible, given the early influence of Alexander von Humboldt. But this view fails to do justice to other scientific traditions. Darwin was a protégé of the Englishman John Stevens Henslow and was a follower of the Scott Charles Lyell. He had important debts to French scientists, notably Henri Milne-Edwards, Etienne and Isidore Geoffroy Saint-Hilaire, and Alphonse de Candolle. Many Germans were quite supportive of Darwin, but not all of these were encumbered by idealistic metaphysical baggage. Both Darwin and Anton Dohrn treated science as very much a cosmopolitan enterprise.

Here, a closer look is taken at the critical question of whether Wallace's manuscript-accompanying letter represented a reply to the Darwin letter that arrived in Ternate on 9 March; it is concluded that it very probably did not.

    As in 2009 the scientific world celebrates two hundreds years from the birthday of Charles Darwin and one hundred and fifty from the publication of The Origin of Species, an analysis of his complete work is performed, looking for any mention of bacteria. But it seems that the great naturahst never took knowledge about its existence, something rather improbable in a time when the discovery of bacteria shook the medical world, or he deliberately ignored them, not finding a place for such microscopic beings into his theory of evolution. But the bacteria badly affected his familiar life, killing scarlet fever one of his children and worsening to death the evolution of tuberculosis of his favourite Annie. Darwin himself could suffer the sickness of Chagas, whose etiological agent has a similar level to bacteria in the scale of evolution.

  7. Mate choice and sexual selection: what have we learned since Darwin? (United States)

    Jones, Adam G; Ratterman, Nicholas L


    Charles Darwin laid the foundation for all modern work on sexual selection in his seminal book The Descent of Man, and Selection in Relation to Sex. In this work, Darwin fleshed out the mechanism of sexual selection, a hypothesis that he had proposed in The Origin of Species. He went well beyond a simple description of the phenomenon by providing extensive evidence and considering the far-reaching implications of the idea. Here we consider the contributions of Darwin to sexual selection with a particular eye on how far we have progressed in the last 150 years. We focus on 2 key questions in sexual selection. First, why does mate choice evolve at all? And second, what factors determine the strength of mate choice (or intensity of sexual selection) in each sex? Darwin provided partial answers to these questions, and the progress that has been made on both of these topics since his time should be seen as one of the great triumphs of modern evolutionary biology. However, a review of the literature shows that key aspects of sexual selection are still plagued by confusion and disagreement. Many of these areas are complex and will require new theory and empirical data for complete resolution. Overall, Darwin's contributions are still surprisingly relevant to the modern study of sexual selection, so students of evolutionary biology would be well advised to revisit his works. Although we have made significant progress in some areas of sexual selection research, we still have much to accomplish.

  8. Darwin and his Mathematical Inspirations (United States)

    Pugliese, Andrea


    I have been kindly asked by the organizers of the BIOCOMP2007 conference to provide a short sketch of Charles Darwin's contribution to science, and of the role mathematics has played in his discoveries and in subsequent developments. I felt flattered by the invitation but rather unfit to it, since I have no particular expertise in evolutionary theory, and even less in its history; eventually, I decided to accept the invitation, appreciating the opportunity to read some more about Darwin, and the importance of making his contribution better known, at a time where teaching at school the theory of evolution is coming under attack also in Italy (perhaps under American influence). I hope to be able here to give a glimpse of the history of Darwinian thought, and of some current research areas, that will lead some readers towards further reading. There are many excellent books available now about Darwin and Darwinian theory, and my presentation is based on many of them, listed in the Bibliography; I found especially illuminating the book by Gayon Darwinism's Struggle for Survival, a history of theoretical Darwinism illustrating the scientific content, and the philosophical implications, of the debates on evolutionary theory at Darwin's time and up to the "modern synthesis".

    This year is especially important in the history of the theory of evolution; 2009 is the bicentennial anniversary of the birth of Charles Darwin and the sesquicentennial anniversary of his publication, The Origin of Species. Darwin visited the Galapagos Islands as a young man, which greatly influenced his thinking. My son Jim and I had the good fortune to visit these islands in January 2009 and see firsthand what led Darwin to arrive at his monumental insights into the origins of life on this planet. I have described my observations and related some of this experience to the ear, nose, and throat, albeit with whimsy in several instances. Nonetheless, some of the adaptations in the animals on these unique islands may have bearing on my hypotheses related to the incidence and pathogenesis of otitis media in humans. It is hoped the reader will share my enthusiasm for the experience we had on these fantastic islands and tour them in the future.

  16. Systemic darwinism. (United States)

    Winther, Rasmus Grønfeldt


    Darwin's 19th century evolutionary theory of descent with modification through natural selection opened up a multidimensional and integrative conceptual space for biology. We explore three dimensions of this space: explanatory pattern, levels of selection, and degree of difference among units of the same type. Each dimension is defined by a respective pair of poles: law and narrative explanation, organismic and hierarchical selection, and variational and essentialist thinking. As a consequence of conceptual debates in the 20th century biological sciences, the poles of each pair came to be seen as mutually exclusive opposites. A significant amount of 21st century research focuses on systems (e.g., genomic, cellular, organismic, and ecological/global). Systemic Darwinism is emerging in this context. It follows a "compositional paradigm" according to which complex systems and their hierarchical networks of parts are the focus of biological investigation. Through the investigation of systems, Systemic Darwinism promises to reintegrate each dimension of Darwin's original logical space. Moreover, this ideally and potentially unified theory of biological ontology coordinates and integrates a plurality of mathematical biological theories (e.g., self-organization/structure, cladistics/history, and evolutionary genetics/function). Integrative Systemic Darwinism requires communal articulation from a plurality of perspectives. Although it is more general than these, it draws on previous advances in Systems Theory, Systems Biology, and Hierarchy Theory. Systemic Darwinism would greatly further bioengineering research and would provide a significantly deeper and more critical understanding of biological reality.

  1. Darwin as a plant scientist: a Southern Hemisphere perspective. (United States)

    Hopper, Stephen D; Lambers, Hans


    Events around the world this year celebrate the bicentenary of the birth of Charles Darwin (1809-1882) and the sesquicentenary of publication of his most important work, The Origin of Species (Darwin 1859). The associated plethora of books and papers now appearing to commemorate Darwin's work continue the traditional emphasis on his zoological and geological contributions. There has been some recent attention directed towards Darwin's relatively unsung but significant accomplishments as a botanist. Here, we bring together a review of Darwin's botanical discoveries and experiments and relevant aspects of his geological investigations, with a focus on the Southern Hemisphere. This is a relatively unexplored aspect of Darwin's contributions that yields some new insights meriting future research.

  2. The Darwins and Wells: from revolution to evolution. (United States)

    Wade, Nicholas J


    In the biography of his grandfather (Erasmus Darwin), Charles Darwin hinted that his father (Robert Darwin) had received parental assistance in conducting and writing his medical thesis (which concerned afterimages). The experiments also involved visual vertigo, and they were elaborated by the senior Darwin in his Zoonomia, published in 1794. Erasmus Darwin's interpretation was in terms of trying to pursue peripheral afterimages formed during rotation; it was at variance with one published two years earlier by William Charles Wells, who had investigated the visual consequences of body rotation when the body is subsequently still. Wells penned two retorts to the Darwins' theory; although they were not accepted by Erasmus, he did devise a human centrifuge, models of which were employed in later studies of vertigo. Wells's ideas on evolution were expressed in a paper delivered to the Royal Society (in 1813) but not published in its Transactions. Commenting on the case of a white woman, part of whose skin was black, he proposed a process of change that was akin to natural selection. His ideas were acknowledged by Charles Darwin in the fourth edition of On the Origin of Species.

  5. Quantum Darwinism (United States)

    Zurek, Wojciech Hubert


    Quantum Darwinism describes the proliferation, in the environment, of multiple records of selected states of a quantum system. It explains how the quantum fragility of a state of a single quantum system can lead to the classical robustness of states in their correlated multitude; shows how effective `wave-packet collapse' arises as a result of the proliferation throughout the environment of imprints of the state of the system; and provides a framework for the derivation of Born's rule, which relates the probabilities of detecting states to their amplitudes. Taken together, these three advances mark considerable progress towards settling the quantum measurement problem.

  9. Darwin and Spencer on the origin of music: is music the food of love? (United States)

    Kleinman, Kim


    Finding an evolutionary explanation for the origins of music serves as a rich test of broader ideas on the emergence of mind and the evolution of mental processes. Charles Darwin and Herbert Spencer both offered evolutionary explanations for the origins of music, indicating the importance of the question for these two leading nineteenth-century students of "descent with modification." Their discussion unfolded between the publication of Spencer's "The origin and function of music" in 1857 and Darwin's commentaries on music in The Descent of Man in 1871 with an addendum Spencer offered to his original article in light of Darwin's views. They had conflicting views on the lines of causation, asked differing questions, and had fundamentally different approaches. Their exchange laid the foundation for the discussion among contemporary adaptationists and nonadaptationists and contributed to the thinking of those who argue for Mixed Origins of Music or that it is a Transformative Technology of Mind. © 2015 Elsevier B.V.

    The Gaia hypothesis of James Lovelock was co-developed with and vigorously promoted by Lynn Margulis, but most mainstream Darwinists scorned and still do not accept the notion. They cannot imagine selection for global stability being realized at the level of the individuals or species that make up the biosphere. Here I suggest that we look at the biogeochemical cycles and other homeostatic processes that might confer stability - rather than the taxa (mostly microbial) that implement them - as the relevant units of selection. By thus focusing our attentions on the "song", not the "singers", a Darwinized Gaia might be developed. Our understanding of evolution by natural selection would however need to be stretched to accommodate differential persistence as well as differential reproduction. Copyright © 2017 Elsevier Ltd.

  11. More than a Mentor: Leonard Darwin's Contribution to the Assimilation of Mendelism into Eugenics and Darwinism. (United States)

    Serpente, Norberto


    This article discusses the contribution to evolutionary theory of Leonard Darwin (1850-1943), the eighth child of Charles Darwin. By analysing the correspondence Leonard Darwin maintained with Ronald Aylmer Fisher in conjunction with an assessment of his books and other written works between the 1910s and 1930s, this article argues for a more prominent role played by him than the previously recognised in the literature as an informal mentor of Fisher. The paper discusses Leonard's efforts to amalgamate Mendelism with both Eugenics and Darwinism in order for the first to base their policies on new scientific developments and to help the second in finding a target for natural selection. Without a formal qualification in biological sciences and as such mistrusted by some "formal" scientists, Leonard Darwin engaged with key themes of Darwinism such as mimicry, the role of mutations on speciation and the process of genetic variability, arriving at important conclusions concerning the usefulness of Mendelian genetics for his father's theory.

    Stoelhorst, J.W.


    The recent debate about the value of Darwinism as a source of ontological foundations for evolutionary economics reduces to a disagreement about whether or not the causal logic of Darwinism applies to economic evolution. However, this logic has not yet been fully specified. While the explanantia of

  17. Darwinism and environmentalism


    Garvey, Brian


    What implications does Darwinism have for our attitude towards the environment? At first sight, it might look as though Darwinism is not friendly towards environmental concerns. Darwinism is often thought to paint a picture of ruthless competition between, as well as within, species. Moreover, Darwinism may be thought to encourage a view of the environment as something to be exploited for self-interested gain. The present paper proposes a more positive view. It will be argued that mutual bene...

  18. The "Annie hypothesis": did the death of his daughter cause Darwin to "give up Christianity"? (United States)

    Van Wyhe, John; Pallen, Mark J


    This article examines one of the most widely believed episodes in the life of Charles Darwin, that the death of his daughter Annie in 1851 caused the end of Darwin's belief in Christianity, and according to some versions, ended his attendance of church on Sundays. This hypothesis, it is argued, is commonly treated as a straightforward true account of Darwin's life, yet there is little or no supporting evidence. Furthermore, we argue, there is sufficient evidence that Darwin's loss of faith occurred before Annie's death.

  1. Danes commemorating Darwin: apes and evolution at the 1909 anniversary. (United States)

    Hjermitslev, Hans Henrik


    This article analyses the Danish 1909 celebrations of the centenary of Charles Darwin's birth on 12 February 1809. I argue that the 1909 meetings, lectures and publications devoted to Darwin and his theory of evolution by natural selection can be characterised by ambivalence: on the one hand, tribute to a great man of science who established a new view of nature and, on the other hand, scepticism towards the Darwinian mechanism of natural selection and the wider religious and political implications drawn from his theory. The article examines both professional and popular commemorative activities, focusing primarily on celebratory articles carried in widely circulated magazines and newspapers. I identify three types of interpretations of Darwin's ideas which I characterise as 'radical', 'evangelical' and 'safe' science. These different positions were closely linked to the political and cultural divisions of the periodical press. Moreover, my analysis of the popular press offers a solid basis for asserting that to most people Darwinism was associated with human evolution, primarily the relationship between man and apes, while more sophisticated discussions about the crisis of Darwinism prominent among naturalists played only a secondary role in the public arena. This article demonstrates the value of using newspapers as historical sources when looking for public images of Darwin, popular receptions of Darwinism and representations of science in general.

  2. Understanding phototropism: from Darwin to today. (United States)

    Holland, Jennifer J; Roberts, Diana; Liscum, Emmanuel


    Few individuals have had the lasting impact on such a breadth of science as Charles Darwin. While his writings about time aboard the HMS Beagle, his study of the Galapagos islands (geology, fauna, and flora), and his theories on evolution are well known, less appreciated are his studies on plant growth responses to a variety of environmental stimuli. In fact, Darwin, together with the help of his botanist son Francis, left us an entire book, 'The power of movements in plants', describing his many, varied, and insightful observations on this topic. Darwin's findings have provided an impetus for an entire field of study, the study of plant tropic responses, or differential growth (curvature) of plant organs in response to directional stimuli. One tropic response that has received a great deal of attention is the phototropic response, or curvature response to directional light. This review summarizes many of the most significant advancements that have been made in our understanding of this response and place these recent findings in the context of Darwin's initial observations.

    The clergyman N.F.S. Grundtvig's followers, who constituted a major fraction within the Danish Evangelical-Lutheran Established Church, were the most vocal Danish commentators on the religious consequences of Charles Darwin's theory of evolution from 1859 to 1914. While evangelicals and high......-churchmen within the church remained critical of evolution throughout the period, the Grundtvigians were divided over the issue. Orthodox Grundtvigians criticized Darwinism on philosophical and biblical grounds, while liberal neo-Grundtvigians came to terms with evolution by combining Grundtvig's critique...

  5. From Darwin to constructivism: the evolution of grounded theory. (United States)

    Hall, Helen; Griffiths, Debra; McKenna, Lisa


    To explore the evolution of grounded theory and equip the reader with a greater understanding of the diverse conceptual positioning that is evident in the methodology. Grounded theory was developed during the modernist phase of research to develop theories that are derived from data and explain human interaction. Its philosophical foundations derive from symbolic interactionism and were influenced by a range of scholars including Charles Darwin and George Mead. Rather than a rigid set of rules and procedures, grounded theory is a way of conceptualising data. Researchers demonstrate a range of perspectives and there is significant variation in the way the methodology is interpreted and executed. Some grounded theorists continue to align closely with the original post-positivist view, while others take a more constructivist approach. Although the diverse interpretations accommodate flexibility, they may also result in confusion. The grounded theory approach enables researchers to align to their own particular world view and use methods that are flexible and practical. With an appreciation of the diverse philosophical approaches to grounded theory, researchers are enabled to use and appraise the methodology more effectively.

  6. Spanish Darwinian iconography: Darwin and evolutionism portrayed in Spanish press cartoons. (United States)

    Domínguez, Martí; Mateu, Anna


    The theory of evolution has played a major role in the press since it was put forward by Charles Darwin in 1859. Its key role in biology and human philosophy is reflected by its presence in press cartoons, sections where the image of social reality is depicted in a more direct and satirical light. Through cartoons, artists have used their ingenuity or wit to portray one of the most controversial scientific figures of the past two centuries. This study examines the views portrayed by Spanish cartoonists about Charles Darwin and evolutionary theory in 2009, the bicentenary of the naturalist's birth and the celebration of 150 years since the publication of On the Origin of Species. These cartoons show how the controversy between Darwinism and religion remain latent in the heart of Spanish society, and how the figure of Darwin has become one of the main icons of science.

    ás condiciones ante desafios estresantes. Dado que la teoría convencional de disyuntivas racionales convencional es insuficiente esto plantea un reto para que futuras investigaciones consideren al pensamiento evolucionista como una alternativa a la hora de estudiar sistemas con altos niveles de emprenderismo por necesidad, alta desigualdad y alta felicidad. Es seguramente  un terreno fructífero e interesante.   As of century XIX, two different paths were taken in history of economic science. Almost simultaneously, the darwinian revolution and the marginalist revolution took place but their respective "ulterior motif" are opposed one from the other. The theories of Darwin about the evolution of the life on Earth and the evolution of the species by means of the natural selection, became no less than a challenge to the dominant vision of the world: the Newtonian one (Witt 1999. This challenge to the Newtonian ideal, was influenced, paradoxically, by intellectual stimuli of thinkers outside biology. These influences emanated of the social philosophy of " laissez faire" during the XVIII century and beggining of century XIX. Within Darwin´s correspondence with Herbert Spencer, stands out the clear influence of the minds of economists-philosophers like Adam Smith, from the so-called School of Edinburgh, and Robert Malthus. The paradox is that nowadays Darwin, in return, influences modern economists. The darwinian revolution in the modern economy consists of showing capitalism like a evolutionary process explained by processes of the change of patterns in the relations between entities. But great part of this study of darwinian influence does not have to do with the study of Biology itself. It is related to the principles and concepts that define the evolucionary mechanism that is foundation of the development of the modern evolutionary theory. What we can learn from the study of the natural system and its related disciplines in the field of the social thinking in the adaptability

    Con motivo de la gentil designación de la Junta Directiva de la Academia a presentar el comentario a la exposición del académico Felipe Guhl, sobre el periodo americano de Charles Darwin en el siglo XIX, me pareció que debía buscar las fuentes de la eventual presencia de Darwin, o de sus ideas, en nuestro país. Así es que, muy brevemente, trataré de mostrar a Ustedes lo que encontré al respecto en tiempos pre-darwinistas -en lo que se denominaba el Nuevo Reino de Granada- y, luego, en tiempos post-darwinistas.

    Gracias a los trabajos sobre la ciencia en la Colonia que hemos venido desarrollando en el Instituto de Genética Humana en compañía del académico Jaime Bernal, lo primero que nos vino a la mente, al comentar sobre esta sesión en días pasados, fueron las páginas que habíamos leído en El Orinoco Ilustrado del padre José Gumilla, S.J. (1686-1750, publicado en 1741 casi cien años antes del viaje del Beagle. En el capítulo titulado “De las primeras gentes que pasaron a la América y el modo”, se refiere Gumilla a la hipótesis del padre José de Acosta, S.J. (1540-1600, quien en su obra Historia natural y moral de las indias, escrita en el Perú en 1590, había ya postulado el estrecho que el danés Vitus Bering (1681-1741 describiría casi 150 años después, en 1741, cuando El Orinoco ilustrado salía de la imprenta en España. Veamos cómo se refirió Gumilla a las predicciones de su correligionario:

  13. Evolutionary ethics from Darwin to Moore. (United States)

    Allhoff, Fritz


    Evolutionary ethics has a long history, dating all the way back to Charles Darwin. Almost immediately after the publication of the Origin, an immense interest arose in the moral implications of Darwinism and whether the truth of Darwinism would undermine traditional ethics. Though the biological thesis was certainly exciting, nobody suspected that the impact of the Origin would be confined to the scientific arena. As one historian wrote, 'whether or not ancient populations of armadillos were transformed into the species that currently inhabit the new world was certainly a topic about which zoologists could disagree. But it was in discussing the broader implications of the theory...that tempers flared and statements were made which could transform what otherwise would have been a quiet scholarly meeting into a social scandal' (Farber 1994, 22). Some resistance to the biological thesis of Darwinism sprung from the thought that it was incompatible with traditional morality and, since one of them had to go, many thought that Darwinism should be rejected. However, some people did realize that a secular ethics was possible so, even if Darwinism did undermine traditional religious beliefs, it need not have any effects on moral thought. Before I begin my discussion of evolutionary ethics from Darwin to Moore, I would like to make some more general remarks about its development. There are three key events during this history of evolutionary ethics. First, Charles Darwin published On the Origin of the Species (Darwin 1859). Since one did not have a fully developed theory of evolution until 1859, there exists little work on evolutionary ethics until then. Shortly thereafter, Herbert Spencer (1898) penned the first systematic theory of evolutionary ethics, which was promptly attacked by T.H. Huxley (Huxley 1894). Second, at about the turn of the century, moral philosophers entered the fray and attempted to demonstrate logical errors in Spencer's work; such errors were alluded

  14. The necessity of Darwin: this journal's tribute to the most influential scientist of all time. (United States)

    Sessions, Stanley K; Macgregor, Herbert C


    Charles Darwin is considered by many to be one of the most influential scientists of all time. His theory of evolution via natural selection was astonishingly prescient in terms of what modern biology has revealed in the 150 years since the publication of The Origin of Species, especially since Darwin was unaware of even the most fundamental aspects of transmission genetics, not to mention molecular biology. Here we speculate what impact it would have had on Darwin's thinking if he had known what we now know about molecular biology and cytogenetics.

  15. Exploration and Exploitation of Victorian Science in Darwin's Reading Notebooks


    Murdock, Jaimie; Allen, Colin; DeDeo, Simon


    Search in an environment with an uncertain distribution of resources involves a trade-off between exploitation of past discoveries and further exploration. This extends to information foraging, where a knowledge-seeker shifts between reading in depth and studying new domains. To study this decision-making process, we examine the reading choices made by one of the most celebrated scientists of the modern era: Charles Darwin. From the full-text of books listed in his chronologically-organized r...

  16. Did Darwin change his mind about the Fuegians? (United States)

    Radick, Gregory


    Shocked by what he considered to be the savagery he encountered in Tierra del Fuego, Charles Darwin ranked the Fuegians lowest among the human races. An enduring story has it, however, that Darwin was later so impressed by the successes of missionaries there, and by the grandeur they discovered in the native tongue, that he changed his mind. This story has served diverse interests, religious and scientific. But Darwin in fact continued to view the Fuegians as he had from the start, as lowly but improvable. And while his case for their unity with the other human races drew on missionary evidence, that evidence concerned emotional expression, not language. Copyright 2010 Elsevier Ltd.

  17. Darwin and Reductionisms: Victorian, Neo-Darwinian and Postgenomic Biologies

    Directory of Open Access Journals (Sweden)

    Angelique Richardson


    Full Text Available This article compares the open-ended Darwinism of Charles Darwin, George Lewes, George Eliot and Thomas Hardy with reductive post-Weismann and early eugenist views and more recent neo-Darwinian ideas including literary Darwinism. It argues that some Victorians had a clear sense of the complexities of the natural world, and of the centrality of environment to life. This awareness contrasts with the processes of divorce and isolation that underpin neo-Darwinian understandings of evolutionary development. But biologists and philosophers of biology are now emphasising the complex and dynamic relations between organism and environment in ways that would have appealed to Darwin’s contemporaries. The article establishes that there are significant parallels between mid-Victorian and postgenomic thought.

  18. Looking at Darwin: portraits and the making of an icon. (United States)

    Browne, Janet


    With increased attention on the visual in the history of science, there is renewed interest in the role of portraiture and other forms of personal imagery in constructing scientific reputation and the circulation of scientific ideas. This essay indicates some directions in which researchers could push forward by studying the dissemination of pictures and portraits of Charles Darwin. Selected portraits are discussed, with particular attention paid to their circulation. The mode of production and original intent of these portraits is briefly addressed, but the thrust of the argument is to highlight subsequent shifts in usage. While self-fashioning is an important part of the story, it is useful also to dwell on the rise and diversification of printed media in conjunction with escalating interest in Darwin as a celebrity figure. Historicizing the variety of opportunities that people have had of "looking"at Darwin adds considerably to our understanding of scientific fame.

  20. Engaging with Lyell: Alfred Russel Wallace's Sarawak Law and Ternate papers as reactions to Charles Lyell's Principles of Geology. (United States)

    Costa, J T


    Alfred Russel Wallace (1823-1913) and Charles Darwin (1809-1882) are honored as the founders of modern evolutionary biology. Accordingly, much attention has focused on their relationship, from their independent development of the principle of natural selection to the receipt by Darwin of Wallace's essay from Ternate in the spring of 1858, and the subsequent reading of the Wallace and Darwin papers at the Linnean Society on 1 July 1858. In the events of 1858 Wallace and Darwin are typically seen as central players, with Darwin's friends Charles Lyell (1797-1875) and Joseph Dalton Hooker (1817-1911) playing supporting roles. This narrative has resulted in an under-appreciation of a more central role for Charles Lyell as both Wallace's inspiration and foil. The extensive anti-transmutation arguments in Lyell's landmark Principles of Geology were taken as the definitive statement on the subject. Wallace, in his quest to solve the mystery of species origins, engaged with Lyell's arguments in his private field notebooks in a way that is concordant with his engagement with Lyell in the 1855 and 1858 papers. I show that Lyell was the object of Wallace's Sarawak Law and Ternate papers through a consideration of the circumstances that led Wallace to send his Ternate paper to Darwin, together with an analysis of the material that Wallace drew upon from the Principles. In this view Darwin was, ironically, intended for a supporting role in mediating Wallace's attempted dialog with Lyell.

    Full Text Available In response to Steven Shapin’s query in the 'London Review of Books', 'Why such homage?', 'I look at Darwin as a metaphor for creativity, and how Darwin, as evidenced in his own metaphysical notebooks, imagined and performed acts of creation in his pursuit of science. Many of Darwin’s ideas were first conceptualised imaginatively, instinctively almost. In this way, he created concepts, rather than simply discovering them. I include a brief discussion of my experience of rendering Darwin and his life into a portrait in 75 poems and also a discussion of the bio-pic Creation'. As species change over time, but are still related, so a portrait of Darwin is a descendent of the historical man and his words, but is no longer the historical man. 

  6. Darwin in disguise. (United States)

    Derry, J F


    Darwinism appears in many more academic areas than just evolutionary biology. New disciplines are created out of its fusion with existing fields of study. However, this practise is criticised for a lack of evidence-based justification, and for adopting gene-oriented reductionism in the social sciences. This article briefly considers seven examples of new disciplines for which Darwinism has been appropriated. In each case, succinct background information precedes quotes provided for this purpose by a leading researcher.

  7. Our Way to Understand the World: Darwin's Controversial Inheritance (United States)

    Schmidt-Salomon, Michael

    Shortly after he had completed the first draft of his theory of evolution in 1844, Charles Darwin wrote to his friend Joseph Hooker, the botanist, that publishing the theory seemed to him "like confessing a murder" (Glaubrecht 2009, p. 161). Right from the beginning, Darwin was aware of the far-reaching impact his theory would have. And this was probably one of the main reasons for his postponing the publication of his ideas for such a long time. After the completion of the 230 page text in 1844, it was another 15 years (!) before his famous book On the Origin of Species was published. Since that time 150 years have passed, but the theory of evolution is as controversial as ever. Darwin's dangerous idea is still putting many traditional world views through some very hard tests. This is the central theme to which I have devoted the following thoughts. I have divided my study into three parts: I shall start by shedding some light on the conflict between Darwin's challenging idea and traditional (Christian) beliefs, a conflict that has lasted till this very day. In the second part, I want to focus on the ideological abuse of the theory of evolution. The third and final part introduces Julian Huxley's concept of 'evolutionary humanism', which links Darwin's scientific inheritance with a distinctly humanist ethic.

  8. Race, language, and mental evolution in Darwin's descent of man. (United States)

    Alter, Stephen G


    Charles Darwin was notoriously ambiguous in his remarks about the relationship between human evolution and biological race. He stressed the original unity of the races, yet he also helped to popularize the notion of a racial hierarchy filling the gaps between the highest anthropoids and civilized Europeans. A focus on Darwin's explanation of how humans initially evolved, however, shows that he mainly stressed not hierarchy but a version of humanity's original mental unity. In his book The Descent of Man, Darwin emphasized a substantial degree of mental development (including the incipient use of language) in the early, monogenetic phase of human evolution. This development, he argued, necessarily came before primeval man's numerical increase, geographic dispersion, and racial diversification, because only thus could one explain how that group was able to spread at the expense of rival ape-like populations. This scenario stood opposed to a new evolutionary polygenism formulated in the wake of Darwin's Origin of Species by his ostensible supporters Alfred Russel Wallace and Ernst Haeckel. Darwin judged this outlook inadequate to the task of explaining humanity's emergence. (c) 2007 Wiley Periodicals, Inc.

    The nineteenth century theologian, author and poet Charles Kingsley was a notable populariser of Darwinian evolution. He championed Darwin's cause and that of honesty in science for more than a decade from 1859 to 1871. Kingsley's interpretation of evolution shaped his theology, his politics and his views on race. The relationship between men and apes set the context for Kingsley's consideration of these issues. Having defended Darwin for a decade in 1871 Kingsley was dismayed to read Darwin's account of the evolution of morals in Descent of Man. He subsequently distanced himself from Darwin's conclusions even though he remained an ardent evolutionist until his death in 1875.

  12. Vitalism and the Darwin Debate (United States)

    Henderson, James


    There are currently both scientific and public debates surrounding Darwinism. In the scientific debate, the details of evolution are in dispute, but not the central thesis of Darwin's theory; in the public debate, Darwinism itself is questioned. I concentrate on the public debate because of its direct impact on education in the United States. Some…

    from classical natural theology. When Darwin discovered the dynamic process of natural selection, he rejected the old teleological argument as formulated by William Paley. However, he was never able to ignore the powerful experience of the beauty and complexity of an intelligently designed universe......, as a whole. He corresponded with Asa Gray on religious themes, particularly touching the problem of pain and intelligent design in nature. The term “intelligent design” was probably introduced by William Whewell. Principally for theological and philosophical reasons, Darwin could only accept the concept...

  14. Charles Lyell and scientific thinking in geology (United States)

    Virgili, Carmina


    Charles Lyell (1797-1875) was born at Kinnordy, Scotland. His father, an amateur botanist, and his grandfather, a navigator, gave him very soon a taste for the observation of the Nature. He went to the Oxford University to study classical literature, but he also followed the geological course of William Buckland. After having been employed as jurist for some years, in 1827 he decided on a career of geologist and held the chair of geology of the King's College of London, from 1831 on. He was a contemporary of Cuvier, Darwin, von Humboldt, Hutton, Lavoisier, and was elected 'membre correspondant' of the 'Académie des sciences, France', in January 1862. Charles Lyell is one of the eminent geologists who initiated the scientific thinking in geology, in which his famous volumes of the Principles of Geology were taken as the authority. These reference volumes are based on multiple observations and field works collected during numerous fieldtrips in western Europe (principally Spain, France, and Italy) and North America. To his name are attached, among others: ( i) the concept of uniformitarism (or actualism), which was opposed to the famous catastrophism, in vogue at that time, and which may be summarized by the expression "The present is the key to the past"; ( ii) the division of the Tertiary in three series denominated Eocene, Miocene, and Pliocene, due to the study of the age of strata by fossil faunas; ( iii) the theory according to which the orogenesis of a mountain chain, as the Pyrenees, results from different pulsations on very long time scales and was not induced by a unique pulsation during a short and intense period. The uniformity of the laws of Nature is undeniably a principle Charles Lyell was the first to state clearly and to apply to the study of the whole Earth's crust, which opened a new era in geology.

  16. An Amphibious Being: How Maritime Surveying Reshaped Darwin's Approach to Natural History. (United States)

    Sponsel, Alistair


    This essay argues that Charles Darwin's distinctive approach to studying distribution and diversity was shaped by his face-to-face interactions with maritime surveyors during the voyage of H.M.S. Beagle (1831-1836). Introducing their hydrographic surveying methods into natural history enabled him to compare fossil and living marine organisms, to compare sedimentary rocks to present-day marine sediments, and to compare landscapes to submarine topology, thereby realizing Charles Lyell's fanciful ambition for a superior form of geology that might be practiced by an "amphibious being." Darwin's theories of continental uplift, coral reef formation, and the origin of species all depended on his amphibious natural history. This essay contributes to our understanding of theorizing in nineteenth-century natural history by illustrating that specific techniques of observing and collecting could themselves help to generate a particular theoretical orientation and, indeed, that such practical experiences were a more proximate source of Darwin's "Humboldtian" interest in distribution and diversity than Alexander von Humboldt's writings themselves. Darwin's debt to the hydrographers became obscured in two ways: through the "funneling" of credit produced by single-authorship publication in natural history and the "telescoping" of memory by which Darwin's new theories made him recall his former researches as though he had originally undertaken them for the very purpose of producing the later theory.

  17. Stability of congruent Darwin ellipsoids

    International Nuclear Information System (INIS)

    Tassoul, M.


    The problem of synchronous oscillations of congruent Darwin ellipsoids is reconsidered. Contrary to results obtained by Chandrasekhar, it is shown that along a Darwin sequence the configurations remain stable with respect to ellipsoidal disturbances until they become too closely spaced. The precise limit which separates stable from unstable systems is found. Apart from some minor differences the Darwin sequence is the exact analog of the Roche sequence

  18. Introducing Darwinism to Toronto's post-1887 reconstituted medical school. (United States)

    Court, John P M


    Charles Darwin's scientific paradigm was largely welcomed in Canadian academic biology and medicine, while reaction among other faculty and laypeople ranged from interest to outrage. In 1874, Ramsay Wright, a Darwinian-era biologist from Edinburgh, was appointed to the University of Toronto's Chair of Natural History. Over his 38-year career Wright integrated the evolutionary perspective into medical and biology teaching without accentuating its controversial source. He also applied the emerging German experimental research model and laboratory technology. This study identifies five categories of scientific and personal influences upon Wright through archival research on biographical sources and his writings.

  19. Neutrino physics with DARWIN (United States)

    Benabderrahmane, M. L.


    DARWIN (DARk matter WImp search with liquid xenoN) will be a multi-ton dark matter detector with the primary goal of exploring the entire experimentally accessible parameter space for weakly interacting massive particles (WIMPs) over a wide mass-range. With its 40 tonne active liquid xenon target, low-energy threshold and ultra-low background level, DARWIN can also search for other rare interactions. Here we present its sensitivity to low-energy solar neutrinos and to neutrinoless double beta decay. In a low-energy window of 2-30 keV a rate of 105/year, from pp and 7Be neutrinos can be reached. Such a measurement, with 1% precision will allow testing neutrinos models. DARWIN could also reach a competitive half-life sensitivity of 8.5 · 1027 y to the neutrinoless double beta decay (0νββ) of 136Xe after an exposure of 140 t×y of natural xenon. Nuclear recoils from coherent scattering of solar neutrinos will limit the sensitivity to WIMP masses below 5 GeV/c2, and the event rate from 8B neutrinos would range from a few to a few tens of events per tonne and year, depending on the energy threshold of the detector. Deviations from the predicted but yet unmeasured neutrino flux would be an indication for physics beyond the Standard Model

  20. Substantive uniformitarianism and Darwinism

    Energy Technology Data Exchange (ETDEWEB)

    Hsu, K.J.


    Darwin's theory of evolution has two themes: common descent and natural selection. The first has been controversial from the beginning to the present day, but is now well supported by geological and biological evidence. The idea of natural selection was inspired by Malthus' Essay on the Principle of Population and by the Weltanschauung of his time. Geological evidence, commonly negative, was dismissed as artifact of imperfect geological record. Variation, adaptation, and survival of the fittest are the three steps of natural selection. Adaptation implies the presence of stable environments as the goal; changes, if any, had to be gradual, slow enough for organisms to adapt. The definition of fitness also depends upon frame of reference; fitness has no meaning in a rapidly changing world. Recent geochemical, sedimentological, and paleontological studies revealed past occurrences of convulsive environmental changes as probably causes of biotic crises. Extinction was often not, as Darwin believed, the consequence of multiplication of species and selection of the fittest. Extinction could be the cause of several episodes of accelerated evolution when ecologic niches had been liberated after a catastrophe. The geological investigations of the century after Darwin indicated the inadequacy of those ideas which had been postulated on the basis of social philosophy.

  1. A history of altruism focusing on Darwin, Allee and E.O. Wilson. (United States)

    Domondon, Andrew T


    The problem of altruism refers to the apparent difficulty in reconciling the existence of altruists, individuals who reduce their own fitness to increase the fitness of others, with natural selection. A historical and philosophical overview of solutions to this apparent contradiction is presented through a close reading of the key texts of Charles Darwin, Warder C. Allee and Edward O. Wilson. Following an analysis of Darwin's explanation for altruism, I examine the ideas of group selection and kin selection advanced by Allee and Wilson, respectively, Attention is also given to the philosophical implications each associated with their respective solutions.

  7. Darwin as a geologist in Africa – dispelling the myths and unravelling a confused knot

    Directory of Open Access Journals (Sweden)

    Sharad Master


    Full Text Available Two myths persist concerning the role played by Charles Darwin as a geologist in Africa during his epic voyage around the world (1831–1836. The first myth is that Darwin was a completely self-taught geologist, with no formal training. The second myth is that it was Darwin who finally solved the problem of the granite–schist contact at the famous Sea Point coastal exposures in Cape Town, after deliberately setting out to prove his predecessors wrong. These myths are challenged by the now ample evidence that Darwin had excellent help in his geological education from the likes of Robert Jameson, John Henslow and Adam Sedgwick. The story of Darwin and his predecessors at the Sea Point granite contact has become confused, and even conflated, with previous descriptions by Basil Hall (1813 and Clark Abel (1818. Here, the historical record is unravelled and set straight, and it is shown from the evidence of his notebooks that Darwin was quite unaware of the outcrops in Cape Town. His erudite account of the contact was a result of the 8 years spent in writing and correspondence after his return to England and not because of his brilliant insights on the outcrop, as the myth would have it. While there has been little to indicate Darwin’s landfalls in Africa, a new plaque now explains the geology of the Sea Point Contact, and includes a drawing of Darwin’s ship, the Beagle, and quotes from his work.

    Full Text Available Taking as a starting point Brandon's account of the principle of natural selection, we argue that it is possible to consider such a principle as bearing the same status of the principle of causation, to wit, that of a methodological rule whose function would be to introduce a "teleological mode of inquiring the living". This way of understanding the principle of natural selection will drive us into an interpretation of Darwinism that is close to that one argued for by Daniel Dennett.

    Anne-Marie Baron


    Full Text Available Charles Bovary est probablement le personnage qui a été le plus transformé par les cinéastes qui ont adapté le roman de Flaubert. Si les premiers adaptateurs l’ont traité en victime, peu à peu, le cinéma a commencé à souligner la dimension néfaste sous-jacente du personnage et à lui faire porter une large part de responsabilité dans la descente aux enfers d’Emma. Depuis Pierre Renoir, touchant et authentique, jusqu’à Gregg Edelman, le mari de Little children qui fantasme sur les photos d’une pin-up virtuelle, en passant par les images plus ou moins pathétiques ou ridicules de Van Heflin, Aribert Wäscher, Alberto Bello, Jean-François Balmer, Farooq Shaikh ou Luis-Miguel Cintra, Charles, plus que tout autre personnage du roman, a subi une incroyable métamorphose en s’ancrant dans la civilisation de chacun des pays et de chacune des décennies successives qui l’ont porté à l’écran.From the 1930s to the present, Charles Bovary is probably the most altered character in the adaptations of Flaubert’s novel. The first directors made a victim of him, but gradually, the cinema began to emphasize his deleterious dimension and attributed to him a large part of the responsibility for Emma’s grief. From Pierre Renoir, touching and authentic, to Gregg Edelman, who fantasizes on a pornographic website in Todd Field’s Little Children, the more or less pathetic or ridiculous portrayals given by Van Heflin, Aribert Wäscher,Alberto Bello, Jean-François Balmer, Farooq Shaikh or Luis-Miguel Cintra, show that more than any other character in the novel, Charles has been submitted to a serious metamorphosis by being interpreted on screen according to each country’s civilization and the successive decades of filming.

    Nicholson, Charles C; Bales, James W; Palmer-Fortune, Joyce E; Nicholson, Robert G


    The orchid genera Catasetum employs a hair-trigger activated, pollen release mechanism, which forcibly attaches pollen sacs onto foraging insects in the New World tropics. This remarkable adaptation was studied extensively by Charles Darwin and he termed this rapid response "sensitiveness." Using high speed video cameras with a frame speed of 1000 fps, this rapid release was filmed and from the subsequent footage, velocity, speed, acceleration, force and kinetic energy were computed.

    Hjermitslev, Hans Henrik

    In the 1870s, when Charles Darwin's On the Origin of Species and Descent of Man were translated into Danish by the botanist-turned-poet J. P. Jacobsen, evolutionary thought played a seminal role in the modern breakthrough advocated by the freethinker and literary critic Georg Brandes. A group...... of students and artists assembled around Brandes in the capital of Copenhagen - the only Danish city hosting a university in the late nineteenth century - and used Darwinism in their cultural struggle against what they regarded as reactionary Christian and conservative values which dominated in the country....... At the same time in the village of Askov in rural Jutland, a liberal fraction of the Evangelical-Lutheran State Church, the Grundtvigians, had a stronghold at their high-profile folk high school. Here materialism and Darwinism associated with the Brandes circle were tabooed and later condemned. However...

  13. Darwin, Hume, Morgan, and the verae causae of psychology. (United States)

    Clatterbuck, Hayley


    Charles Darwin and C. Lloyd Morgan forward two influential principles of cognitive ethological inference that yield conflicting results about the extent of continuity in the cognitive traits of humans and other animals. While these principles have been interpreted as reflecting commitments to different senses of parsimony, in fact, both principles result from the same vera causa inferential strategy, according to which "We ought to admit no more causes of natural things, than such as are both true and sufficient to explain their appearances". Instead, the conflict stems from Darwin's and Morgan's views about the true causes of human psychology. Darwin holds a thoroughly Humean philosophy of the human mind, from which he infers significant continuity between human and animal minds. In contrast, Morgan argues that Humean cognitive mechanisms cannot account for a class of uniquely human behaviors, and therefore, he concludes that there is a significant discontinuity between human and animal cognition. This historical debate is informative for current controversies in comparative psychology. Copyright © 2016 Elsevier Ltd. All rights reserved.

  14. Trees and networks before and after Darwin

    Directory of Open Access Journals (Sweden)

    Ragan Mark A


    Full Text Available Abstract It is well-known that Charles Darwin sketched abstract trees of relationship in his 1837 notebook, and depicted a tree in the Origin of Species (1859. Here I attempt to place Darwin's trees in historical context. By the mid-Eighteenth century the Great Chain of Being was increasingly seen to be an inadequate description of order in nature, and by about 1780 it had been largely abandoned without a satisfactory alternative having been agreed upon. In 1750 Donati described aquatic and terrestrial organisms as forming a network, and a few years later Buffon depicted a network of genealogical relationships among breeds of dogs. In 1764 Bonnet asked whether the Chain might actually branch at certain points, and in 1766 Pallas proposed that the gradations among organisms resemble a tree with a compound trunk, perhaps not unlike the tree of animal life later depicted by Eichwald. Other trees were presented by Augier in 1801 and by Lamarck in 1809 and 1815, the latter two assuming a transmutation of species over time. Elaborate networks of affinities among plants and among animals were depicted in the late Eighteenth and very early Nineteenth centuries. In the two decades immediately prior to 1837, so-called affinities and/or analogies among organisms were represented by diverse geometric figures. Series of plant and animal fossils in successive geological strata were represented as trees in a popular textbook from 1840, while in 1858 Bronn presented a system of animals, as evidenced by the fossil record, in a form of a tree. Darwin's 1859 tree and its subsequent elaborations by Haeckel came to be accepted in many but not all areas of biological sciences, while network diagrams were used in others. Beginning in the early 1960s trees were inferred from protein and nucleic acid sequences, but networks were re-introduced in the mid-1990s to represent lateral genetic transfer, increasingly regarded as a fundamental mode of evolution at least for

  16. Neural Darwinism and consciousness. (United States)

    Seth, Anil K; Baars, Bernard J


    Neural Darwinism (ND) is a large scale selectionist theory of brain development and function that has been hypothesized to relate to consciousness. According to ND, consciousness is entailed by reentrant interactions among neuronal populations in the thalamocortical system (the 'dynamic core'). These interactions, which permit high-order discriminations among possible core states, confer selective advantages on organisms possessing them by linking current perceptual events to a past history of value-dependent learning. Here, we assess the consistency of ND with 16 widely recognized properties of consciousness, both physiological (for example, consciousness is associated with widespread, relatively fast, low amplitude interactions in the thalamocortical system), and phenomenal (for example, consciousness involves the existence of a private flow of events available only to the experiencing subject). While no theory accounts fully for all of these properties at present, we find that ND and its recent extensions fare well.

    Bowler, Peter J


    The article sums up a number of points made by the author concerning the response to Darwinism in the late nineteenth and early twentieth centuries, and repeats the claim that a proper understanding of the theory's impact must take account of the extent to which what are now regarded as the key aspects of Darwin's thinking were evaded by his immediate followers. Potential challenges to this position are described and responded to.

  18. Exploration and exploitation of Victorian science in Darwin's reading notebooks. (United States)

    Murdock, Jaimie; Allen, Colin; DeDeo, Simon


    Search in an environment with an uncertain distribution of resources involves a trade-off between exploitation of past discoveries and further exploration. This extends to information foraging, where a knowledge-seeker shifts between reading in depth and studying new domains. To study this decision-making process, we examine the reading choices made by one of the most celebrated scientists of the modern era: Charles Darwin. From the full-text of books listed in his chronologically-organized reading journals, we generate topic models to quantify his local (text-to-text) and global (text-to-past) reading decisions using Kullback-Liebler Divergence, a cognitively-validated, information-theoretic measure of relative surprise. Rather than a pattern of surprise-minimization, corresponding to a pure exploitation strategy, Darwin's behavior shifts from early exploitation to later exploration, seeking unusually high levels of cognitive surprise relative to previous eras. These shifts, detected by an unsupervised Bayesian model, correlate with major intellectual epochs of his career as identified both by qualitative scholarship and Darwin's own self-commentary. Our methods allow us to compare his consumption of texts with their publication order. We find Darwin's consumption more exploratory than the culture's production, suggesting that underneath gradual societal changes are the explorations of individual synthesis and discovery. Our quantitative methods advance the study of cognitive search through a framework for testing interactions between individual and collective behavior and between short- and long-term consumption choices. This novel application of topic modeling to characterize individual reading complements widespread studies of collective scientific behavior. Copyright © 2016 Elsevier B.V. All rights reserved.

    Barry, Herbert


    12 fictional characters named Charles or Charley are contained in eight of the 14 completed novels by Charles Dickens. Most of the author's namesakes have humorous attributes, an unusually close relationship with one or more other characters, and a happy subsequent life. Three stages of the author's adult life are youthful, mature, and after separation from his wife. The fictional namesakes are most humorous in the author's youthful stage and least humorous after separation from his wife. The 12 fictional namesakes of Charles Dickens are compared with the two fictional namesakes of Jane Austen.

  20. Dog fight: Darwin as animal advocate in the antivivisection controversy of 1875. (United States)

    Feller, David Allan


    The traditional characterization of Charles Darwin as a strong advocate of physiological experimentation on animals was posited in Richard French's Antivivisection and medical science in Victorian England (1975), where French portrayed him as a soldier in Thomas Huxley's efforts to preserve anatomical experimentation on animals unfettered by government regulation. That interpretation relied too much on, inter alia, Huxley's own description of the legislative battles of 1875, and shared many historians' propensity to foster a legacy of Darwin as a leader among a new wave of scientists, even where personal interests might indicate a conflicting story. Animal rights issues concerned more than mere science for Darwin, however, and where debates over other scientific issues failed to inspire Darwin to become publicly active, he readily joined the battle over vivisection, helping to draft legislation which, in many ways, was more protective of animal rights than even the bills proposed by his friend and anti-vivisectionist, Frances Power Cobbe. Darwin may not have officially joined Cobbe's side in the fight, but personal correspondence of the period between 1870 and 1875 reveals a man whose first interest was to protect animals from inhumane treatment, and second to protect the reputations of those men and physiologists who were his friends, and who he believed incapable of inhumane acts. On this latter point he and Cobbe never did reach agreement, but they certainly agreed on the humane treatment of animals, and the need to proscribe various forms of animal experimentation.

  1. Darwin's triggering mechanism of volcano eruptions (United States)

    Galiev, Shamil


    Charles Darwin wrote that ‘… the elevation of many hundred square miles of territory near Concepcion is part of the same phenomenon, with that splashing up, if I may so call it, of volcanic matter through the orifices in the Cordillera at the moment of the shock;…' and ‘…a power, I may remark, which acts in paroxysmal upheavals like that of Concepcion, and in great volcanic eruptions,…'. Darwin reports that ‘…several of the great chimneys in the Cordillera of central Chile commenced a fresh period of activity ….' In particular, Darwin reported on four-simultaneous large eruptions from the following volcanoes: Robinson Crusoe, Minchinmavida, Cerro Yanteles and Peteroa (we cite the Darwin's sentences following his The Voyage of the Beagle and researchspace. auckland. ac. nz/handle/2292/4474). Let us consider these eruptions taking into account the volcano shape and the conduit. Three of the volcanoes (Minchinmavida (2404 m), Cerro Yanteles (2050 m), and Peteroa (3603 m)) are stratovolcanos and are formed of symmetrical cones with steep sides. Robinson Crusoe (922 m) is a shield volcano and is formed of a cone with gently sloping sides. They are not very active. We may surmise, that their vents had a sealing plug (vent fill) in 1835. All these volcanoes are conical. These common features are important for Darwin's triggering model, which is discussed below. The vent fill material, usually, has high level of porosity and a very low tensile strength and can easily be fragmented by tension waves. The action of a severe earthquake on the volcano base may be compared with a nuclear blast explosion of the base. It is known, that after a underground nuclear explosion the vertical motion and the surface fractures in a tope of mountains were observed. The same is related to the propagation of waves in conical elements. After the explosive load of the base. the tip may break and fly off at high velocity. Analogous phenomenon may be generated as a result of a

  2. An Ottoman response to Darwinism: İsmail Fennî on Islam and evolution. (United States)

    Bilgili, Alper


    The Scopes trial (1925) fuelled discussion in the United States on the social and political implications of Darwinism. For the defenders of the 1925 Tennessee law - which prohibited the teaching of Darwinism in schools - Darwinism was, amongst other things, responsible for the German militarism which eventually led to the First World War. This view was supported by İsmail Fennî, a late Ottoman intellectual, who authored a book immediately after the trial which aimed to debunk scientific materialism. In it, he claimed that Darwinism blurred the distinction between man and beast and thus destroyed the foundations of morality. However, despite his anti-Darwinist stance, İsmail Fennî argued against laws forbidding the teaching of Darwinism in schools, and emphasized that even false theories contributed to scientific improvement. Indeed, because of his belief in science he claimed that Muslims should not reject Darwinism if it were supported by future scientific evidence. If this turned out to be the case, then religious interpretations should be revised accordingly. This article contributes to the literature on early Muslim reactions to Darwinism by examining the views of İsmail Fennî, which were notably sophisticated when compared with those of the anti-religious Darwinist and anti-Darwinist religious camps that dominated late Ottoman intellectual life.

  3. The prominent absence of Alfred Russel Wallace at the Darwin anniversaries in Germany in 1909, 1959 and 2009. (United States)

    Hossfeld, Uwe; Olsson, Lennart


    It is well known that the contribution of Alfred Russell Wallace (1823-1913) to the development of the "Darwinian" principle of natural selection has often been neglected. Here we focus on how the three anniversaries to celebrate the origin of the Darwin-Wallace theory in Germany in 1909, in 1959 in the divided country, as well as in 2009, have represented Charles Robert Darwin's and Alfred Russell Wallace's contributions. We have analyzed books and proceedings volumes related to these anniversaries, and the main result is that Wallace was almost always ignored, or only mentioned in passing. In 1909, Ernst Haeckel gave a talk in Jena, later published under the title The worldview of Darwin and Lamarck (Das Weltbild von Darwin und Lamarck), but not as the Darwin-Wallace concept. Haeckel mentions Wallace only once. In two important proceedings volumes from the 1959 anniversaries, Wallace was ignored. The only fair treatment of Wallace is given in another book, a collection of documents edited by Gerhard Heberer, for which the author selected nine key documents and reprinted excerpts (1959). Three of them were articles by Wallace, including the Sarawak- and Ternate-papers of 1855 and 1858, respectively. An analysis of the dominant themes during the celebrations of 2009 shows that none of the six topics had much to do with Wallace and his work. Thus, the tendency to exclude Alfred Russell Wallace is an international phenomenon, and largely attributable to the "Darwin industry".

  5. Charles Bonnet syndrome: a review. (United States)

    Schadlu, Anita P; Schadlu, Ramin; Shepherd, J Banks


    The aging of the population and the resultant increase in the number of patients with low vision due to age-related macular degeneration and other ocular diseases necessitate an increase in awareness of the Charles Bonnet syndrome among ophthalmic care providers. The clinical features of Charles Bonnet syndrome have been described by several different authors as formed visual hallucinations due to disturbances of the visual system in patients who are otherwise mentally normal. Theories regarding the causes underlying the Charles Bonnet syndrome are multifaceted and offer insight into the function of the visual system. The incidence of the Charles Bonnet syndrome varies among different population groups, but is underdiagnosed in most settings. Recent case reports of treatment options involve varied pharmacologic interventions, but visual improvement and patient reassurance remain the mainstays of treatment. As Charles Bonnet syndrome becomes more prevalent as the population ages, all physicians who care for low vision or elderly patients should be aware of its clinical characteristics and treatment options. Understanding of this syndrome by caregivers will lead to decreased anxiety among the patients who experience it. Further exploration of treatment options will be necessary in the future.

  6. Gehlen, Darwin e la salamandra

    Directory of Open Access Journals (Sweden)



    Full Text Available Gehlen, Darwin and the Salamander Arnold Gehlen creates a theory of man as “lacking being” that leads to a theory of a “superior being”. Man is radically different from animal, and Gehlen uses the biological idea of human neoteny to refuse the Darwinian theory of human evolution. However his arguments are preconceived and ineffectual.

  7. Gilson, Darwin, and Intelligent Design

    Directory of Open Access Journals (Sweden)

    Desmond J. FitzGerald


    Full Text Available The article starts with stating the fact that today there is an increasing recognition of difficulties with Darwinism accompanied by vigorous responses on the part of Darwin’s defenders; among the instances of challenge to the dominant theory, one can find a book of Gilson, From Aristotle to Darwin and Back Again, and those behind the Intelligent Design movement. Inrelating the book of Gilson to the ID proponents, the author concludes that, while in some ways they are on the same side in opposing the anti-creation thrust of Darwinism, Gilson is neutral on the validity or truth of Darwin’s biological hypothesis. Gilson, however, whose book preceded the ID movement by some twenty years, seeks to analyze Darwinism from the perspective of the classical philosophy of nature. He well understands that, according to modern scientific method, final causes are excluded from consideration, but he calls for a biophilosophy which will be open to the reality of human experience as Aristotle was and recognize that teleology is present in nature. According to him, even if teleology seems to be a contestable explanation, chance as understood by Darwinists is the pure absence of explanation.

  8. Darwin and Lincoln: their legacy of human dignity. (United States)

    Earls, Felton


    The legacy of Charles Darwin and Abraham Lincoln is to champion the dignity inherent in every human being. The moment of the bicentennial of their births provides an opportunity to celebrate and reflect on ways they have shaped our understanding and commitment to human rights. The naturalist and the constitutional lawyer, so different in circumstance and discipline, were morally allied in the mission to eradicate slavery. The profound lessons to be extracted from the lives of these two icons bind us to the agonizing reality that nearly 150 years after Gettysburg and the publication of the Descent of Man, and Selection in Relation to Sex, there remains much work to do toward advancing the security, respect, and equality of our species. This article describes how Darwin and Lincoln's inspiring legacies guided the author's personal choices as a scientist and activist. The essay concludes with a set of questions and challenges that confront us, foremost among which is the need to balance actions in response to the violation of negative rights by actions in the pursuit of positive rights.

  9. Deceived by orchids: sex, science, fiction and Darwin. (United States)

    Endersby, Jim


    Between 1916 and 1927, botanists in several countries independently resolved three problems that had mystified earlier naturalists - including Charles Darwin: how did the many species of orchid that did not produce nectar persuade insects to pollinate them? Why did some orchid flowers seem to mimic insects? And why should a native British orchid suffer 'attacks' from a bee? Half a century after Darwin's death, these three mysteries were shown to be aspects of a phenomenon now known as pseudocopulation, whereby male insects are deceived into attempting to mate with the orchid's flowers, which mimic female insects; the males then carry the flower's pollen with them when they move on to try the next deceptive orchid. Early twentieth-century botanists were able to see what their predecessors had not because orchids (along with other plants) had undergone an imaginative re-creation: Darwin's science was appropriated by popular interpreters of science, including the novelist Grant Allen; then H.G. Wells imagined orchids as killers (inspiring a number of imitators), to produce a genre of orchid stories that reflected significant cultural shifts, not least in the presentation of female sexuality. It was only after these changes that scientists were able to see plants as equipped with agency, actively able to pursue their own, cunning reproductive strategies - and to outwit animals in the process. This paper traces the movement of a set of ideas that were created in a context that was recognizably scientific; they then became popular non-fiction, then popular fiction, and then inspired a new science, which in turn inspired a new generation of fiction writers. Long after clear barriers between elite and popular science had supposedly been established in the early twentieth century, they remained porous because a variety of imaginative writers kept destabilizing them. The fluidity of the boundaries between makers, interpreters and publics of scientific knowledge was a highly

  10. Darwin and the geological controversies over the steady-state worldview in the 1830s. (United States)

    Gohau, Gabriel


    In the first part of this paper, I will show that although Darwin's geological works only covered the first years of his scientific career, these played a non-negligible role in the earth sciences of the mid-nineteenth century. His intellectual proximity with Charles Lyell often made him his disciple. This is indeed the case with respect to debates over 'gradual' soil movements and 'catastrophic' soil movements, and for 'steady-state' cycles as opposed to 'directionalistic' ones. This being said, it is also true that in South America Darwin saw geological processes which were incompatible with Lyell's explanations. It must therefore be recognized that Darwin held a middle-of-the-road position between uniformitarianism (Lyell) and catastrophism (Humbolt and von Buch), at least as far as some geological questions were concerned. In the second part of the paper, debates on geological issues during Darwin's active years will be put in the methodological context of the Scientific Revolution of the seventeenth century.

  11. Looking for Darwin's footprints in the microbial world

    Energy Technology Data Exchange (ETDEWEB)

    Shapiro, B. Jesse; David, Lawrence A.; Friedman, Jonathan; Alm, Eric J.


    As we observe the 200th anniversary of Charles Darwin's birthday, microbiologists interested in the application of Darwin's ideas to the microscopic world have a lot to celebrate: an emerging picture of the (mostly microbial) Tree of Life at ever-increasing resolution, an understanding of horizontal gene transfer as a driving force in the evolution of microbes, and thousands of complete genome sequences to help formulate and refine our theories. At the same time, quantitative models of the microevolutionary processes shaping microbial populations remain just out of reach, a point that is perhaps most dramatically illustrated by the lack of consensus on how (or even whether) to define bacterial species. We summarize progress and prospects in bacterial population genetics, with an emphasis on detecting the footprint of positive Darwinian selection in microbial genomes.

  12. Going the whole orang: Darwin, Wallace and the natural history of orangutans. (United States)

    van Wyhe, John; Kjærgaard, Peter C


    This article surveys the European discovery and early ideas about orangutans followed by the contrasting experiences with these animals of the co-founders of evolution by natural selection, Charles Darwin and Alfred Russel Wallace. The first non-human great ape that both of them interacted with was the orangutan. They were both profoundly influenced by what they saw, but the contexts of their observations could hardly be more different. Darwin met orangutans in the Zoological Gardens in London while Wallace saw them in the wild in Borneo. In different ways these observations helped shape their views of human evolution and humanity's place in nature. Their findings played a major role in shaping some of the key questions that were pursued in human evolutionary studies during the rest of the nineteenth century. Copyright © 2015 The Authors.

  16. 'The art itself is nature': Darwin, domestic varieties and the scientific revolution. (United States)

    Inkpen, S Andrew


    Common to both the scientific and Darwinian revolutions were discussions challenging the distinction between art and nature. Was art a part of nature? Could art be used as a model for nature? This intellectual congruence, however, is more than just nominal. Charles Darwin and Asa Gray, for example, were well-aware of the 17th century debates which preceded them through the works of such revered English writers as William Shakespeare and Thomas Browne. Furthermore, they used their understandings of these debates to inform and express their own thinking about the relation between artificial and natural selection. Copyright © 2014 Elsevier Ltd.

  17. Darwin and the divine experiment

    DEFF Research Database (Denmark)

    Gregersen, Niels Henrik; Kjærgaard, Peter C.


    In Denmark Darwin’s theory of evolution was known early on and viewed with respect, but did not make immediate scientific converts. In the 1870s, when Darwinism was promoted by free thinkers, public debates began to flourish, but religious reactions were remarkably few and mostly undramatic. Since...... natural theology was not assumed by Lutheran theologians, the issue of design vs. chance was not prevalent. Discussions focused rather on scripture and the general challenge of naturalism, and if Darwin’s name was included, the concern was human uniqueness and the social consequences of Darwinism....... Religious responses thus targeted the materialism of semi-popular Darwinism more than the substance of Darwin’s theory. Around 1900, however, many aspects of Darwin’s theory were accepted. At that time, however, leading biologists found that Darwin’s theory needed to be complemented by a Lamarckian emphasis...

  18. On Darwin's 'metaphysical notebooks'. I: teleology and the project of a theory. (United States)

    Calabi, L


    Huxley's essay On the Reception of the 'Origin of Species' brings us close to the issue of cause and of why- and how-questions in the understanding of the living world. The present contribution, which is divided into two parts, reviews the problem of Teleology as conceived by Huxley and re-examines Darwin as the author who revealed the existence of a 'foundations problem' in the explanation of an entire realm of nature, i.e., the problem of explaining such realm in terms of its own, specific legality, or iuxta sua propria principia. In the first part the enquiry is mainly focused on the secularization of natural history after Paley; in the second part it is mainly focused on the desubjectivization of the inquiry into natural history after Erasmus Darwin and Lamarck. The second part will be published in the next issue of Rivista di Biologia/Biology Forum. In the first part below an analysis is made of Notebooks M and N. The author disputes the correctness of conceiving them only as the works where Darwin envisages the 'metaphysical' themes later to become the subject of The Expression of the Emotions. He suggests to conceive of them also as the works where Darwin defines the terms of the general project of his own, peculiar evolutionary theory. The author then outlines the intellectual progress of Darwin from the inosculation to the transmutation hypotheses. Darwin's reading of Malthus appears to be analytically decisive, because it offers him the vintage point to attack the metaphysical and theological citadels on the morphological side. Darwin is thus able to re-consider Erasmus' comprehensive zoonomic project, by displacing it, however, from the old idea of the scala naturae to the new one of the "coral of life", and by emphasising the distinction between "the fittest" and "the best" vs. the tradition of Natural Theology.

  1. Darwin's "strange inversion of reasoning". (United States)

    Dennett, Daniel


    Darwin's theory of evolution by natural selection unifies the world of physics with the world of meaning and purpose by proposing a deeply counterintuitive "inversion of reasoning" (according to a 19th century critic): "to make a perfect and beautiful machine, it is not requisite to know how to make it" [MacKenzie RB (1868) (Nisbet & Co., London)]. Turing proposed a similar inversion: to be a perfect and beautiful computing machine, it is not requisite to know what arithmetic is. Together, these ideas help to explain how we human intelligences came to be able to discern the reasons for all of the adaptations of life, including our own.

  2. The Lake Charles CCS Project

    Energy Technology Data Exchange (ETDEWEB)

    Doug Cathro


    The Lake Charles CCS Project is a large-scale industrial carbon capture and sequestration (CCS) project which will demonstrate advanced technologies that capture and sequester carbon dioxide (CO{sub 2}) emissions from industrial sources into underground formations. Specifically the Lake Charles CCS Project will accelerate commercialization of large-scale CO{sub 2} storage from industrial sources by leveraging synergy between a proposed petroleum coke to chemicals plant (the LCC Gasification Project) and the largest integrated anthropogenic CO{sub 2} capture, transport, and monitored sequestration program in the U.S. Gulf Coast Region. The Lake Charles CCS Project will promote the expansion of EOR in Texas and Louisiana and supply greater energy security by expanding domestic energy supplies. The capture, compression, pipeline, injection, and monitoring infrastructure will continue to sequester CO{sub 2} for many years after the completion of the term of the DOE agreement. The objectives of this project are expected to be fulfilled by working through two distinct phases. The overall objective of Phase 1 was to develop a fully definitive project basis for a competitive Renewal Application process to proceed into Phase 2 - Design, Construction and Operations. Phase 1 includes the studies attached hereto that will establish: the engineering design basis for the capture, compression and transportation of CO{sub 2} from the LCC Gasification Project, and the criteria and specifications for a monitoring, verification and accounting (MVA) plan at the Hastings oil field in Texas. The overall objective of Phase 2, provided a successful competitive down-selection, is to execute design, construction and operations of three capital projects: (1) the CO{sub 2} capture and compression equipment, (2) a Connector Pipeline from the LLC Gasification Project to the Green Pipeline owned by Denbury and an affiliate of Denbury, and (3) a comprehensive MVA system at the Hastings oil field.

  3. Darwin's legacy and the study of primate visual communication. (United States)

    de Waal, Frans B M


    After Charles Darwin's The Expression of the Emotions in Man and Animals, published in 1872, we had to wait 60 years before the theme of animal expressions was picked up by another astute observer. In 1935, Nadezhda Ladygina-Kohts published a detailed comparison of the expressive behavior of a juvenile chimpanzee and of her own child. After Kohts, we had to wait until the 1960s for modern ethological analyses of primate facial and gestural communication. Again, the focus was on the chimpanzee, but ethograms on other primates appeared as well. Our understanding of the range of expressions in other primates is at present far more advanced than that in Darwin's time. A strong social component has been added: instead of focusing on the expressions per se, they are now often classified according to the social situations in which they typically occur. Initially, quantitative analyses were sequential (i.e., concerned with temporal associations between behavior patterns), and they avoided the language of emotions. I will discuss some of this early work, including my own on the communicative repertoire of the bonobo, a close relative of the chimpanzee (and ourselves). I will provide concrete examples to make the point that there is a much richer matrix of contexts possible than the common behavioral categories of aggression, sex, fear, play, and so on. Primate signaling is a form of negotiation, and previous classifications have ignored the specifics of what animals try to achieve with their exchanges. There is also increasing evidence for signal conventionalization in primates, especially the apes, in both captivity and the field. This process results in group-specific or "cultural" communication patterns.

  4. Social Darwinism in modern China

    Institute of Scientific and Technical Information of China (English)

    XU Jilin; XIAO Zhiwei


    After evolutionary theory was introduced in China,Herbert Spencer's interpretation of it in the form of social Darwinism persuaded the Chinese that if they wanted to strengthen their nation,they would have to accept the brutal truth of natural selection,in which the principle of survival of the fittest rules.This version of evolutionary theory,when combined with the pragmatic thrust of Confucianism and the realpolitik of legalism from China's indigenous tradition,started a storm of materialism and utilitarianism in modern China.In the process,the traditional social order based on the rule of propriety (li) was completely subverted and replaced by a new order predicated on the rule of competition and power.This development produced a new mental outlook that privileged power over everything else,seriously undermined the rules of ethics and caused serious political consequences in the late Qing and early Republican period.This intellectual development may have contributed to ending the dynastic rule in China,but it was also responsible for ruining the newborn Republican China.The Chinese intellectuals of the May Fourth era critically reflected on this problematic legacy.While still believing in the notion of progress,they abandoned social Darwinism and embraced the idea of evolution through mutual assistance.Thus began a historical shift in modern China from focusing on wealth and power to focusing on civilization as China's salvation.

  5. Marine Sciences: from natural history to ecology and back, on Darwin's shoulders

    Directory of Open Access Journals (Sweden)

    Ferdinando Boero


    Full Text Available The naturalist Charles Darwin founded modern ecology, considering in a single conceptual framework the manifold aspects regarding the organization of life at various levels of complexity and its relationship with the physical world. The development of powerful analytical tools led to abandon Darwin's natural history and to transform naturalists, as Darwin labelled himself, into the practitioners of more focused disciplines, aimed at tackling specific problems that considered the various aspects of the organization of life in great detail but, also, in isolation from each other. Among the various disciplines that stemmed from the Darwinian method, ecology was further split into many branches, and marine ecology was no exception. The compartmentalization of the marine realm into several sub-domains (e.g., plankton, benthos, nekton led to neglect of the connections linking the various parts that were separated for the ease of analyses that, in this way, prevented synthetic visions. The way marine sciences were studied also led to separate visions depending on the employed tools, so that ship-based biological oceanography developed almost separately from marine station-based marine biology. The necessity of putting together such concepts as biodiversity and ecosystem functioning is rapidly leading to synthetic approaches that re-discover the historical nature of ecology, leading to the dawn of a new natural history.

  6. Charles Peyrou: 1918-2003

    CERN Multimedia


    Charles Peyrou, who was one of the outstanding personalities at CERN for thirty years, passed away on 6 April 2003. Born in Oloron-Sainte-Marie (France) on 18 May 1918, Charles Peyrou studied at the Ecole Polytechnique, where he attended the first class given by Louis Leprince-Ringuet in 1936. Here, he was part of the small group of enthusiastic physicists who took part in the first cosmic ray experiments. In 1938, the group built its first chamber, a large Wilson chamber in a magnetic field, operating with Geiger counters. After the war, following his appointment as chief engineer of one of the large national technical institutes known as the Corps de l'Etat, he was detached to his old laboratory to resume research on cosmic rays, and a system of two superimposed cloud chambers was set up at the Pic du Midi. This device proved very effective in the study of the strange particles that were starting to be detected at that time. Here, for example, the disintegration of the K meson into a muon and a neutrino wa...

  7. On the origin of death: Paul and Augustine meet Charles Darwin

    Directory of Open Access Journals (Sweden)

    Izak J.J. Spangenberg


    Full Text Available Ever since the 4th century, Christian theologians have linked Romans 5:12–21 with Genesis 2–3. Augustine (354–430, one of the Latin fathers of the Church, propagated the idea of ‘original sin’ according to his reading of these chapters. This idea eventually became a fixed doctrine in Western Christianity and a large number of Christians still believe and proclaim that humans would have lived for ever but for the misconduct of Adam and Eve. They also proclaim that Jesus, through his obedience, death and resurrection, re-established God’s original creation plan. Death was conquered and eternal life can be inherited by all who believe in Jesus as saviour and second Adam. However, since both the introduction of the theory of evolution into biology and the paradigm shift in biblical studies (at the end of the 19th century, the view that death was to be linked to ‘original sin’ came under severe criticism. This article argues that Romans 5:12–21 and Genesis 2–3 do not support the idea of ‘original sin’ and that death is a normal part of life on earth, as argued by evolutionary biologists and proclaimed by many Old Testament texts.

    Dispersion relations from the Darwin (a.k.a., magnetoinductive or magnetostatic) model are given and compared with those of the full electromagnetic model. Analytical and numerical solutions show that the errors from the Darwin approximation can be large even if phase velocity for a low-frequency wave is close to or larger than the speed of light. Besides missing two wave branches associated mainly with the electron dynamics, the coupling branch of the electrons and ions in the Darwin model is modified to become a new artificial branch that incorrectly represents the coupling dynamics of the electrons and ions.

    Alejandro Rosas


      I describe the project of a Darwinian explanation of morality following Darwin’s basic ideas as expressed in The Descent of Man. In contrast to the traditional interpretation, I argue that Darwin did not assume, nor is it necessary to assume in a Darwinian perspective, an inevitable conflict between individual and group selection in the explanation of morality. Both operate in synergy to favor traits that support moral behavior. I also argue that two teachings result from this Darwinian project, one for moral philosophy and the other for the theory of natural selection. The first puts social dilemmas in the heart of human morality; the second puts cooperation in the core of natural selection. I illustrate the second point with recent research into the evolution of multi-cellular organisms.

  14. Quantum Darwinism in hazy environments (United States)

    Zwolak, Michael; Quan, H. T.; Zurek, Wojciech


    Quantum Darwinism provides an information-theoretic framework for the emergence of the classical world from the quantum substrate. It recognizes that we - the observers - acquire our information about the ``systems of interest'' indirectly from their imprints on the environment. Objectivity, a key property of the classical world, arises via the proliferation of redundant information into the environment where many observers can then intercept it and independently determine the state of the system. After a general introduction to this framework, we demonstrate how non-ideal initial states of the environment (e.g., mixed states) affect its ability to act as a communication channel for information about the system. The environment's capacity for transmitting information is directly related to its ability to increase its entropy. Therefore, environments that remain nearly invariant under the Hamiltonian dynamics, such as very mixed states, have a diminished ability to transmit information. However, despite this, the environment almost always redundantly transmits information about the system.

  15. Formalizing Darwinism and inclusive fitness theory. (United States)

    Grafen, Alan


    Inclusive fitness maximization is a basic building block for biological contributions to any theory of the evolution of society. There is a view in mathematical population genetics that nothing is caused to be maximized in the process of natural selection, but this is explained as arising from a misunderstanding about the meaning of fitness maximization. Current theoretical work on inclusive fitness is discussed, with emphasis on the author's 'formal Darwinism project'. Generally, favourable conclusions are drawn about the validity of assuming fitness maximization, but the need for continuing work is emphasized, along with the possibility that substantive exceptions may be uncovered. The formal Darwinism project aims more ambitiously to represent in a formal mathematical framework the central point of Darwin's Origin of Species, that the mechanical processes of inheritance and reproduction can give rise to the appearance of design, and it is a fitting ambition in Darwin's bicentenary year to capture his most profound discovery in the lingua franca of science.

  16. A unified approach to the Darwin approximation

    International Nuclear Information System (INIS)

    Krause, Todd B.; Apte, A.; Morrison, P. J.


    There are two basic approaches to the Darwin approximation. The first involves solving the Maxwell equations in Coulomb gauge and then approximating the vector potential to remove retardation effects. The second approach approximates the Coulomb gauge equations themselves, then solves these exactly for the vector potential. There is no a priori reason that these should result in the same approximation. Here, the equivalence of these two approaches is investigated and a unified framework is provided in which to view the Darwin approximation. Darwin's original treatment is variational in nature, but subsequent applications of his ideas in the context of Vlasov's theory are not. We present here action principles for the Darwin approximation in the Vlasov context, and this serves as a consistency check on the use of the approximation in this setting

  18. Bayesian Methods and Universal Darwinism (United States)

    Campbell, John


    Bayesian methods since the time of Laplace have been understood by their practitioners as closely aligned to the scientific method. Indeed a recent Champion of Bayesian methods, E. T. Jaynes, titled his textbook on the subject Probability Theory: the Logic of Science. Many philosophers of science including Karl Popper and Donald Campbell have interpreted the evolution of Science as a Darwinian process consisting of a `copy with selective retention' algorithm abstracted from Darwin's theory of Natural Selection. Arguments are presented for an isomorphism between Bayesian Methods and Darwinian processes. Universal Darwinism, as the term has been developed by Richard Dawkins, Daniel Dennett and Susan Blackmore, is the collection of scientific theories which explain the creation and evolution of their subject matter as due to the Operation of Darwinian processes. These subject matters span the fields of atomic physics, chemistry, biology and the social sciences. The principle of Maximum Entropy states that Systems will evolve to states of highest entropy subject to the constraints of scientific law. This principle may be inverted to provide illumination as to the nature of scientific law. Our best cosmological theories suggest the universe contained much less complexity during the period shortly after the Big Bang than it does at present. The scientific subject matter of atomic physics, chemistry, biology and the social sciences has been created since that time. An explanation is proposed for the existence of this subject matter as due to the evolution of constraints in the form of adaptations imposed on Maximum Entropy. It is argued these adaptations were discovered and instantiated through the Operations of a succession of Darwinian processes.

  1. Beating the Turkish hollow in the struggle for existence: Darwin, social Darwinism and the Turks. (United States)

    Bilgili, Alper


    Despite the vast literature on Darwinism and race, the way in which Darwin's opinions on race were received and used by non-Western circles has been little studied. In the case of the Turks, Darwin's comments have been related to British-Ottoman relations, and Darwin was blamed for stoking anti-Turkish sentiment within Europe. This allegedly resulted in the British occupation of Egypt in the 19th century, the demise of the Ottoman Empire, as well as contemporary Neo-Nazi arson attacks in Germany which targeted Turkish migrants. Consequently, Turkish anti-Darwinists perceive Darwinism to be not merely a false scientific theory, but also a political-ideological instrument of Western hegemony wielded against Turkey and the Islamic World. Turkish Darwinists who responded to those claims, on the other hand, presented Darwin as an egalitarian who could overcome the prejudices of his social class. Further scrutiny, however, proves both accounts to be over-simplistic. This paper aims to throw some light on the context within which Darwin expressed his opinions on Turks and thus contribute to the broader discussion of the relationship between Darwinism and race. More importantly, it aims to familiarise Western readers with one of the cultures of creationism which is very little known, despite its great impact on Muslim masses. Copyright © 2017 Elsevier Ltd.

  2. Random unitary operations and quantum Darwinism

    International Nuclear Information System (INIS)

    Balaneskovic, Nenad


    We study the behavior of Quantum Darwinism (Zurek, Nature Physics 5, 181-188 (2009)) within the iterative, random unitary operations qubit-model of pure decoherence (Novotn'y et al, New Jour. Phys. 13, 053052 (2011)). We conclude that Quantum Darwinism, which describes the quantum mechanical evolution of an open system from the point of view of its environment, is not a generic phenomenon, but depends on the specific form of initial states and on the type of system-environment interactions. Furthermore, we show that within the random unitary model the concept of Quantum Darwinism enables one to explicitly construct and specify artificial initial states of environment that allow to store information about an open system of interest and its pointer-basis with maximal efficiency. Furthermore, we investigate the behavior of Quantum Darwinism after introducing dissipation into the iterative random unitary qubit model with pure decoherence in accord with V. Scarani et al (Phys. Rev. Lett. 88, 097905 (2002)) and reconstruct the corresponding dissipative attractor space. We conclude that in Zurek's qubit model Quantum Darwinism depends on the order in which pure decoherence and dissipation act upon an initial state of the entire system. We show explicitly that introducing dissipation into the random unitary evolution model in general suppresses Quantum Darwinism (regardless of the order in which decoherence and dissipation are applied) for all positive non-zero values of the dissipation strength parameter, even for those initial state configurations which, in Zurek's qubit model and in the random unitary model with pure decoherence, would lead to Quantum Darwinism. Finally, we discuss what happens with Quantum Darwinism after introducing into the iterative random unitary qubit model with pure decoherence (asymmetric) dissipation and dephasing, again in accord with V. Scarani et al (Phys. Rev. Lett. 88, 097905 (2002)), and reconstruct the corresponding

  3. Darwin without borders? Looking at 'generalised Darwinism' through the prism of the 'hourglass model'. (United States)

    Levit, Georgy S; Hossfeld, Uwe


    This article critically analyzes the arguments of the 'generalized Darwinism' recently proposed for the analysis of social-economical systems. We argue that 'generalized Darwinism' is both restrictive and empty. It is restrictive because it excludes alternative (non-selectionist) evolutionary mechanisms such as orthogenesis, saltationism and mutationism without any examination of their suitability for modeling socio-economic processes and ignoring their important roles in the development of contemporary evolutionary theory. It is empty, because it reduces Darwinism to an abstract triple-principle scheme (variation, selection and inheritance) thus ignoring the actual structure of Darwinism as a complex and dynamic theoretical structure inseparable from a very detailed system of theoretical constraints. Arguing against 'generalised Darwinism' we present our vision of the history of evolutionary biology with the help of the 'hourglass model' reflecting the internal dynamic of competing theories of evolution.

  4. [Darwinism, materialism and the revolution of 1848 in Germany. On the interaction of politics and science]. (United States)

    Junker, T


    In recent years, the question of national styles in science has received increasing attention. The different forms of Darwinism that emerged in the nineteenth century provide an impressive example of the role of non-scientific factors in the development of scientific ideas. Although the reception of Darwinian theory has been acknowledged to differ according to distinct national traditions even in Darwin's time, there have been few systematic efforts to understand the underlying causal factors. Usually these explanations have conceived of the relationship of science to its social and political context as a distortion of science by ideology. In contrast to this picture, I attempt to demonstrate here how a scientific research program was situated in a concrete historical context. The German tradition of Darwinism in the nineteenth century will be described as a coalition of political liberalism, materialism, and morphology. Whereas the liberals used Darwinism to give their anti-religious and progressive program a naturalistic foundation, the morphologists appreciated that Darwinian theory allowed them to dispense with the idealistic origins of their research program, and the materialist were provided with a naturalistic explanation of the origin of organic form.

  5. [Darwin versus Marx? Reflections on a book by Giovanni Jervis]. (United States)

    Cavallaro, Luigi


    Giovanni Jervis'2002 book Individualismo e cooperazione. Psicologia della politica [Individualism and Cooperation: Psychology of Politics] is the outcome of a critical reflection begun by the author at the end of the 1970s in order to explore the manifestations and the problems of cooperation between individuals, and to identify some "universal" psychological factors that could define the role of psychology within politics and constitute an "objective foundation" of any human culture. Although Jervis was, so to speak,favoring Darwin against Marx, it is argued that,from his overall reasoning, several of his arguments actually are in favor of the inevitable "historicity" of individuals, due to the social conditioning they are subjected since birth: too often certain "universalistic" approaches transmit, together with scientific advances (or even without them), well identifiable ideological motives linked to precise and well defined historical and economic interests?

  6. Charles Wagley: mentor and colleague

    Directory of Open Access Journals (Sweden)

    Maxine L. Margolis

    Full Text Available Professor Charles Wagley was my mentor at Columbia University, my colleague at the University of Florida and a dear friend. His influence on me can be summarized in one word: Brazil. From the time I took his course, "Peoples of Brazil", as a first semester graduate student at Columbia I was captivated and most of my subsequent field research and publications have had Brazilian themes. Under Dr. Wagley's direction I did field research for my dissertation in the coffee region of northern Paraná and focused on the shift from coffee cultivation to cattle ranching and the social and economic consequences of that change. My subsequent research in the area involved the impact of frost on this shift in economic base as well as one of its results: the flight of poor Brazilians to Paraguay. Then starting in the late 1980s my research shifted and I began focusing on Brazilian immigrants in New York City. This was part of a growing movement of Brazilians arriving in New York, elsewhere in the United States and in Europe and Japan. Since then most of my subsequent research and publications have been on this new wave of international migrants

  7. [Charles Gerhardt's life and work]. (United States)

    Blondel-Mégrelis, Marika


    Charles Gerhardt's life and work is rather well-known thanks to Grimaux and Tiffeneau. His reform of the equivalents, his classification, his obtention of organic acid anhydrids and his famous Treatise of Organic Chemistry. His active collaboration to the Revue scientifique et industrielle du Docteur Quesneville, the creation of his Comptes-Rendus des Travaux de Chimie. Are not so often quoted. Thanks to his translations and reviews, German chemical advancements became well known in France Gerhardt was Liebig's translator for almost all his life, even through the fluctuations of their personal relation. He was the representative of German chemistry in France. With Auguste Laurent, with whom he is constantly associated, things need to be examined precisely. Laurent and Gerhardt, friends at a moment, cannot be confounded. Though they worked together for some years, they were not engaged in a similar project. Besides an experimentalist, Laurent was essentially a theorician of chemistry, whereas Gerhardt refused to think about atoms and arrangements. Formulas have to describe relations between facts, in no case anything about arrangements. For posterity however, Gerhardt will be, on the same level as Laurent, the creator of modern chemistry doctrines.

  8. Dennett, Darwin, and Skinner Crows

    Directory of Open Access Journals (Sweden)

    Frans Blommaert


    Full Text Available The central theme of this paper is the scientific viewpoint taken for understanding behavioral processes. Two classical viewpoints are formulated by Dennett (the intentional stance and Tinbergen (Tinbergen's four questions. In this paper we argue that the two different viewpoints are linked to the two different processes that underlie complex behavior, namely, the instruction process and the selection process. To zoom in on the similarities and differences between these processes, we model whelk dropping behavior of Northwestern crows as observed by Zach (1978, 1979 from the two different viewpoints: (1 with crows that possess intentional faculties (called Dennett crows, and (2 with crows that possess selectional faculties. The latter type of crows is further divided into a population that is able to adapt over generations only by natural selection (Darwin crows, and a population that, apart from natural selection, is also able to adapt using operant learning (Skinner crows. Salient outcomes are that these two populations need markedly different times to adapt to changes in the environment, and that operant learning needs a value system that is an internal equivalent of the fitness criterion. In conclusion, we propose that understanding behavior should start at a meta-level with identifying whether the nature of the behavioral process under study is intentional or selectional.

  9. Giuseppe Sergi, "champion" of Darwinism? (United States)

    Volpone, Alessandro


    The Italian anthropologist, psychologist and evolutionist Giuseppe Sergi (1841-1936) may be regarded in some respects today as an "atypical" Darwinist, but, almost paradoxically, he was considered a "champion" of Darwinism by colleagues and commentators of his own time. Probably, two aspects of his work are responsible for this apparent anomaly: his faith in the so-called soft inheritance and his claims regarding a theory concerning the polyphyletic origin of human races. The soft inheritance theory, however, was needed by Sergi to support ideas regarding the complexity of inheritance in man, a fact that, in his opinion, could not completely be put down to mechanical laws, and polygeny was useful when trying to rectify the problem concerning the incompleteness of the fossil record. In both cases, it is possible to show that he was involved in supporting Darwinian theory during the most severe crisis of its consensus in Italy and at International level, between the end of the 19th century and the beginning of the 20th. Finally, the apparent unorthodox features which can be found in Sergi's ideas appear to be, in Kuhnian terms, ad hoc hypotheses put forward by Sergi himself in order to support the paradigm.

  12. Darwin and Darwinism: the (alleged) social implications of the origin of species. (United States)

    Orr, H Allen


    Most scientific theories, even revolutionary ones, change the practice of a particular science but have few consequences for culture or society at large. But Darwinism, it has often been said, is different in this respect. Since the publication of The Origin of Species, many have claimed that Darwinism has a number of profound social implications. Here, I briefly consider three of these: the economic, the political, and the religious. I suggest that, for the most part, these supposed implications have been misconstrued or exaggerated. Indeed, it is reasonably clear that the chain of implication sometimes primarily ran in the opposite direction-from, for instance, economics and political theory to Darwinism.

  13. Streamlined Darwin simulation of nonneutral plasmas

    International Nuclear Information System (INIS)

    Hewett, D.W.; Boyd, J.K.


    Efficient, new algorithms that require less formal manipulation than previous implementations have been formulated for the numerical solution of the Darwin model. These new procedures reduce the effort required to achieve some of the advantages that the Darwin model offers. Because the Courant--Friedrichs--Lewy stability limit for radiation modes is eliminated, the Darwin model has the advantage of a substantially larger time-step. Further, without radiation modes, simulation results are less sensitive to enhanced particle fluctation noise. We discuss methods for calculating the magnetic field that avoid formal vector decomposition and offer a new procedure for finding the inductive electric field. This procedure avoids vector decomposition of plasma source terms and circumvents some source gradient issues that slow convergence. As a consequence, the numerical effort required for each of the field time-steps is reduced, and more importantly, the need to specify several nonintuitive boundary conditions is eliminated. copyright 1987 Academic Press, Inc

  14. Charles Brenner: a practitioner's theorist. (United States)

    Friedman, Lawrence


    To avoid certain errors in practice, Charles Brenner offered an holistic substitute for the Freudian structural model of the mind. He used the term compromise formation ambiguously to refer to both actions and states, so as to render unnecessary what he considered artificial, judgmental attitudes embodied in images of psychic structures. He believed that a theory of conflicting structures transforms the phenomenological drama of the patient's actual life-world into an artificial drama of contending intrapsychic parties that may reflect the analyst's values. According to Brenner, the meaning of life, with its desires, fears, and regrets, is structured forever in the first articulation of the family drama, and that is all the structure a practitioner should have in mind. In principle, the ambiguity of the term compromise formation allows for observed continuities in human life, and might have inspired an ambitious theoretician to exploit that option for an account of character, but that aspect of theory moves in a direction opposite to Brenner's practical mission. For the same practical reason Brenner refused to acknowledge gradations of mental operation, such as differences in maturity, or style or level of thinking, so the theory cannot say how change can take place, analytic or otherwise. These lacunae in theory were unblinkingly (if implicitly) accepted in pursuit of Brenner's goal, which was not to polish up theory but to cleanse the analyst's mind of concepts that subtly interfere with the essential nondirectiveness of treatment. His theoretical minimalism and exclusive concern with practical consequences can be recognized as a peculiarly North American attitude to psychoanalysis.

    Mirkin, B M


    The author questions Ghilarov's (2003) claim that Darwinism has high explanatory power in ecology. He is agree with S.V. Meyen who believed that beside synthetic theory of evolution (the popular variant on Darwinism) other explanations of evolution are possible. It is emphasized that several processes (e.g., diversification and unification of species at one trophic level, as well as individual and diffusive coadaptations of species of different levels) can contribute to community evolution. Communities cannot be considered as units of natural selection.

  17. Ethics in actor networks, or: what Latour could learn from Darwin and Dewey. (United States)

    Waelbers, Katinka; Dorstewitz, Philipp


    In contemporary Science, Technology and Society (STS) studies, Bruno Latour's Actor Network Theory (ANT) is often used to study how social change arises from interaction between people and technologies. Though Latour's approach is rich in the sense of enabling scholars to appreciate the complexity of many relevant technological, environmental, and social factors in their studies, the approach is poor from an ethical point of view: the doings of things and people are couched in one and the same behaviorist (third person) vocabulary without giving due recognition to the ethical relevance of human intelligence, sympathy and reflection in making responsible choices. This article argues that two other naturalist projects, the non-teleological virtue ethics of Charles Darwin and the pragmatist instrumentalism of John Dewey can enrich ANT-based STS studies, both, in a descriptive and in a normative sense.

  18. The moral conscience from a neuroethcal Standpoint. From Darwin to Kant

    Directory of Open Access Journals (Sweden)

    Adela Cortina


    Full Text Available The personal moral conscience is one of the keystones of moral life. Darwin went as far as to claim that this constitutes the most important difference between man and the lower animals. Yet the most relevant philosophical proposals of our times (Rawls, Habermas do not expressly deal with this, perhaps because, as Aranguren said, they gave priority to intersubjective ethics over intrasubjective ethics. Without reconstructing that intrasubjective ethics, however, both personal and social life is watered down. In this work an attempt is made to explain what personal moral conscience consists of, what its neurobiological foundations are, and whether these are enough to explain its irreplaceable role in moral life. To answer these questions we will have to go from Darwin to Kant.

  19. Genealogy of John and Charles Bell: their relationship with the children of Charles Shaw of Ayr. (United States)

    Kaufman, M


    The Reverend William Bell had six children who survived infancy. Two of his sons entered the legal profession and two other sons became distinguished anatomists and surgeons--John Bell, said for 20 years to have been the leading operating surgeon in Britain and throughout the world--and Sir Charles Bell, possibly the most distinguished anatomist and physiologist of his day. Information is not known about the fifth son or their sister. Charles Shaw, a lawyer of Ayr, had four sons and two daughters who survived infancy. Two of his sons, John and Alexander, became anatomists and later surgeons at the Middlesex Hospital, and both worked closely with Charles Bell at the Great Windmill Street School of Anatomy. His third son entered the law and his fourth son became a distinguished soldier. The two daughters of Charles Shaw married into the Bell family: Barbara married George Joseph Bell and Marion married Mr (later Sir) Charles Bell.

  2. Combating plant diseases--the Darwin connection. (United States)

    Hollomon, Derek W; Brent, Keith J


    Although Darwin knew of plant diseases, he did not study them as part of his analysis of natural selection. Effective plant disease control has only been developed after his death. This article explores the relevance of Darwin's ideas to three problem areas with respect to diseases caused by fungi: emergence of new diseases, loss of disease resistance bred into plants and development of fungicide resistance. Darwin's concept of change through natural or artificial selection relied on selection of many small changes, but subsequent genetic research has shown that change can also occur through large steps. Appearance of new diseases can involve gene duplication, transfer or recombination, but all evidence points to both host plant resistance and fungicide susceptibility being overcome through point mutations. Because the population size of diseases such as rusts and powdery and downy mildews is so large, all possible point mutations are likely to occur daily, even during moderate epidemics. Overcoming control measures therefore reflects the overall fitness of these mutants, and much resource effort is being directed towards assessment of their fitness, both in the presence and in the absence of selection. While recent developments in comparative genomics have caused some revision of Darwin's ideas, experience in managing plant disease control measures clearly demonstrates the relevance of concepts he introduced 150 years ago. It also reveals the remarkable speed and the practical impact of adaptation in wild microorganism populations to changes in their environment, and the difficulty of stopping or delaying such adaptation.

  3. Edward B. Aveling: the people's Darwin. (United States)

    Paylor, Suzanne


    By the late-19th century, evolutionary theory, known by most people as Darwinism, had earned a reputation as an atheistic theory that challenged religious orthodoxy. From recent historical work we now know a great deal about how those with religious convictions received Darwinian ideas, and the role that professional scientists played in styling and communicating 'Darwinism' to the wider public and between themselves. However, relatively little is known about how Darwinian ideas were received and used by avowedly irreligious groups, and how these groups set about communicating their own version of Darwinism to a public hungry for cheap and accessible science. The activities of the Secularist Edward Bibbins Aveling, a prolific popularizer of Darwinian ideas in the late-19th century, offer a unique insight into this relatively uncharted territory. His work helped to develop the polemic of popular irreligious groups and imbue Darwinism with overtly atheistic connotations; it also engendered unprecedented support for atheism from the general public, and challenged the monopoly that some professional scientists enjoyed over imparting serious scientific knowledge to them.

  5. Inspiration in the harness of daily labor. Darwin, botany, and the triumph of evolution, 1859-1868. (United States)

    Bellon, Richard


    Charles Darwin hoped that a large body of working naturalists would embrace evolution after the Origin of Species appeared in late 1859. He was disappointed. His evolutionary ideas at first made painfully little progress in the scientific community. But by 1863 the tide had turned dramatically, and within five years evolution became scientific orthodoxy in Britain. The Origin's reception followed this peculiar trajectory because Darwin had not initially tied its theory to productive original scientific investigation, which left him vulnerable to charges of reckless speculation. The debate changed with his successful application of evolution to original problems, most notably orchid fertilization, the subject of a well-received book in 1862. Most of Darwin's colleagues found the argument of the Origin convincing when they realized that it functioned productively in the day-to-day work of science-and not before. The conceptual force of the Origin, however outwardly persuasive, acquired full scientific legitimacy only when placed "in the harness of daily labour".

  6. Darwin revisited: The vagus nerve is a causal element in controlling recognition of other's emotions. (United States)

    Colzato, Lorenza S; Sellaro, Roberta; Beste, Christian


    Charles Darwin proposed that via the vagus nerve, the tenth cranial nerve, emotional facial expressions are evolved, adaptive and serve a crucial communicative function. In line with this idea, the later-developed polyvagal theory assumes that the vagus nerve is the key phylogenetic substrate that regulates emotional and social behavior. The polyvagal theory assumes that optimal social interaction, which includes the recognition of emotion in faces, is modulated by the vagus nerve. So far, in humans, it has not yet been demonstrated that the vagus plays a causal role in emotion recognition. To investigate this we employed transcutaneous vagus nerve stimulation (tVNS), a novel non-invasive brain stimulation technique that modulates brain activity via bottom-up mechanisms. A sham/placebo-controlled, randomized cross-over within-subjects design was used to infer a causal relation between the stimulated vagus nerve and the related ability to recognize emotions as indexed by the Reading the Mind in the Eyes Test in 38 healthy young volunteers. Active tVNS, compared to sham stimulation, enhanced emotion recognition for easy items, suggesting that it promoted the ability to decode salient social cues. Our results confirm that the vagus nerve is causally involved in emotion recognition, supporting Darwin's argumentation. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Rethinking Darwin? About Ex‐aptations and Neotenies. Concerning Mickey Mouse, Goofy and likeable mexican Salamanders The theory of evolution by natural selection of Charles Darwin, whose first general exposure dates back to 1859, with the publication of the Origin of Species, is still a matter of intense debate among natural sciences’ scholars and philosophers. After the merger of Darwinian evolutionary research program with the theory of heredity of Gregor Mendel, the mathematical form of population genetics and the analysis of paleontological data (Modern Synthesis and the the important contributions of post-Darwinian authors such as S.J. Gould and N. Eldredge we are entering a new era of great discoveries and news. On the one hand, new data from genetics and paleoanthropology, on the other hand the impetuous development of some fields of applied science such as nanobiotechnology, genetic engineering and synthetic biology put us into the need and the urgency to underline, once again, the relevance and the extraordinary heuristic power of Darwinian research program, an even greater urgency since some authors have announced that we would be at a time to access a post-Darwinian and post-evolutionary era in which man as we actually know it is about to disappear.

  8. JAMSTEC DARWIN Database Assimilates GANSEKI and COEDO (United States)

    Tomiyama, T.; Toyoda, Y.; Horikawa, H.; Sasaki, T.; Fukuda, K.; Hase, H.; Saito, H.


    Introduction: Japan Agency for Marine-Earth Science and Technology (JAMSTEC) archives data and samples obtained by JAMSTEC research vessels and submersibles. As a common property of the human society, JAMSTEC archive is open for public users with scientific/educational purposes [1]. For publicizing its data and samples online, JAMSTEC is operating NUUNKUI data sites [2], a group of several databases for various data and sample types. For years, data and metadata of JAMSTEC rock samples, sediment core samples and cruise/dive observation were publicized through databases named GANSEKI, COEDO, and DARWIN, respectively. However, because they had different user interfaces and data structures, these services were somewhat confusing for unfamiliar users. Maintenance costs of multiple hardware and software were also problematic for performing sustainable services and continuous improvements. Database Integration: In 2017, GANSEKI, COEDO and DARWIN were integrated into DARWIN+ [3]. The update also included implementation of map-search function as a substitute of closed portal site. Major functions of previous systems were incorporated into the new system; users can perform the complex search, by thumbnail browsing, map area, keyword filtering, and metadata constraints. As for data handling, the new system is more flexible, allowing the entry of variety of additional data types. Data Management: After the DARWIN major update, JAMSTEC data & sample team has been dealing with minor issues of individual sample data/metadata which sometimes need manual modification to be transferred to the new system. Some new data sets, such as onboard sample photos and surface close-up photos of rock samples, are getting available online. Geochemical data of sediment core samples will supposedly be added in the near future. Reference: [1] [2] [3]

  9. On Darwin's 'metaphysical notebooks'. II: "Metaphysics" and final cause. (United States)

    Calabi, L


    The first part of this paper was published in Rivista di Biologia/Biology Forum 94 (2001). In the second part below an examination is made of the meaning of the term Metaphysics in some passages of the Darwinian Notebooks for the years 1836-1844. Metaphysics no longer defines a field of philosophical enquiries mainly concerning the being and the essence after the manner of Aristotle; it now refers to a kind of philosophy of mind after the manner of J. Locke's criticism of the Hypokeimenon. However Aristotle's Metaphysics also encompasses a treatment of the idea of causes, and of final cause particularly, in the explanation of events, and in the explanation of natural phenomena especially. The criticism of the idea of final cause in the interpretation of the world of life is one of Darwin's foundational acts in his early years. When conceiving his Système du monde, in the last years of the XVIII Century, Laplace could think that God is a hypothesis not really needed by science, as we are told. For the knowledge of organic nature to attain the status of science, it remained to be shown that since--certain of the exemplariness of Newton's Principles as much as cautious before the mystery of life--did not need the hypothesis of final ends in order to understand and explain the productions of the living nature: not only in the form of that final cause (the First Cause, the Vera Causa) in which Natural Theology still rested, but also in the form of nature's inner finality which still moulded Whewell's Kantian philosophy. Such demonstration is a very important subject in Darwin's early enquiries, where he criticises finalism as a projection of self-conceiving Man, likely inherited from a knowing of causality in nuce to be found also in animals.

  18. On the Origin of Complex Adaptive Traits: Progress Since the Darwin Versus Mivart Debate. (United States)

    Suzuki, Takao K


    The evolutionary origin of complex adaptive traits has been a controversial topic in the history of evolutionary biology. Although Darwin argued for the gradual origins of complex adaptive traits within the theory of natural selection, Mivart insisted that natural selection could not account for the incipient stages of complex traits. The debate starting from Darwin and Mivart eventually engendered two opposite views: gradualism and saltationism. Although this has been a long-standing debate, the issue remains unresolved. However, recent studies have interrogated classic examples of complex traits, such as the asymmetrical eyes of flatfishes and leaf mimicry of butterfly wings, whose origins were debated by Darwin and Mivart. Here, I review recent findings as a starting point to provide a modern picture of the evolution of complex adaptive traits. First, I summarize the empirical evidence that unveils the evolutionary steps toward complex traits. I then argue that the evolution of complex traits could be understood within the concept of "reducible complexity." Through these discussions, I propose a conceptual framework for the formation of complex traits, named as reducible-composable multicomponent systems, that satisfy two major characteristics: reducibility into a sum of subcomponents and composability to construct traits from various additional and combinatorial arrangements of the subcomponents. This conceptual framework provides an analytical foundation for exploring evolutionary pathways to build up complex traits. This review provides certain essential avenues for deciphering the origin of complex adaptive traits. © 2017 Wiley Periodicals, Inc.

  19. Numerical simulation of distorted crystal Darwin width

    International Nuclear Information System (INIS)

    Wang Li; Xu Zhongmin; Wang Naxiu


    A new numerical simulation method according to distorted crystal optical theory was used to predict the direct-cooling crystal monochromator optical properties(crystal Darwin width) in this study. The finite element analysis software was used to calculate the deformed displacements of DCM crystal and to get the local reciprocal lattice vector of distorted crystal. The broadening of direct-cooling crystal Darwin width in meridional direction was estimated at 4.12 μrad. The result agrees well with the experimental data of 5 μrad, while it was 3.89 μrad by traditional calculation method of root mean square (RMS) of the slope error in the center line of footprint. The new method provides important theoretical support for designing and processing of monochromator crystal for synchrotron radiation beamline. (authors)

  20. Phylogenetic inertia and Darwin's higher law. (United States)

    Shanahan, Timothy


    The concept of 'phylogenetic inertia' is routinely deployed in evolutionary biology as an alternative to natural selection for explaining the persistence of characteristics that appear sub-optimal from an adaptationist perspective. However, in many of these contexts the precise meaning of 'phylogenetic inertia' and its relationship to selection are far from clear. After tracing the history of the concept of 'inertia' in evolutionary biology, I argue that treating phylogenetic inertia and natural selection as alternative explanations is mistaken because phylogenetic inertia is, from a Darwinian point of view, simply an expected effect of selection. Although Darwin did not discuss 'phylogenetic inertia,' he did assert the explanatory priority of selection over descent. An analysis of 'phylogenetic inertia' provides a perspective from which to assess Darwin's view. Copyright © 2010 Elsevier Ltd. All rights reserved.

  3. Quantum Darwinism for mixed-state environment (United States)

    Quan, Haitao; Zwolak, Michael; Zurek, Wojciech


    We exam quantum darwinism when a system is in the presence of a mixed environment, and we find a general relation between the mutual information for the mixed-state environment and the change of the entropy of the fraction of the environment. We then look at a particular solvable model, and we numerically exam the time evolution of the ``mutual information" for large environment. Finally we discuss about the exact expressions for all entropies and the mutual information at special time.

  4. Indication for quantum Darwinism in electron billiards (United States)

    Brunner, R.; Akis, R.; Meisels, R.; Kuchar, F.; Ferry, D. K.


    In this paper, we investigate the dynamics in electron billiards by using classical and quantum mechanical calculations. We report on the existence of pointer states in single-dot and double-dot electron billiards. Additionally, we show that the two types of pointer states have the propensity to create offspring, i.e. they can be observed in the individual modes propagating between the external reservoirs. This can be understood as an indication that quantum Darwinism is present in the electron billiards.

  6. Streamlined Darwin methods for particle beam injectors

    International Nuclear Information System (INIS)

    Boyd, J.K.


    Physics issues that involve inductive effects, such as beam fluctuations, electromagnetic (EM) instability, or interactions with a cavity require a time-dependent simulation. The most elaborate time-dependent codes self-consistently solve Maxwell's equations and the force equation for a large number of macroparticles. Although these full EM particle-in-cell (PIC) codes have been used to study a broad range of phenomena, including beam injectors, they have several drawbacks. In an explicit solution of Maxwell's equations, the time step is restricted by a Courant condition. A second disadvantage is the production of anomalously large numerical fluctuations, caused by representing many real particles by a single computational macroparticle. Last, approximate models of internal boundaries can create nonphysical radiation in a full EM simulation. In this work, many of the problems of a fully electromagnetic simulation are avoided by using the Darwin field model. The Darwin field model is the magnetoinductive limit of Maxwell's equations, and it retains the first-order relativistic correction to the particle Lagrangian. It includes the part of the displacement current necessary to satisfy the charge-continuity equation. This feature is important for simulation of nonneutral beams. Because the Darwin model does not include the solenoidal vector component of the displacement current, it cannot be used to study high-frequency phenomena or effects caused by rapid current changes. However, because wave motion is not followed, the Courant condition of a fully electromagnetic code can be exceeded. In addition, inductive effects are modeled without creating nonphysical radiation

  11. Lloyd Morgan's theory of instinct: from Darwinism to neo-Darwinism. (United States)

    Richards, R J


    Darwin's proposal of two sources of instinct--natural selection and inherited habit--fostered among late nineteenth century evolutionists a variety of conflicting notions concerning the mechanisms of evolution. The British comparative psychologist C. Lloyd Morgan was a cardinal figure in restructuring the orthodox Darwinian conception to relieve the confusion besetting it and to meet the demands of the new biology of Weismann. This paper traces the development of Morgan's ideas about instinct against the background of his philosophic assumptions and the views of instinct theorists from Darwin and Romanes to McDougall and Lorenz.

  14. Darwin's explanation of races by means of sexual selection. (United States)

    Millstein, Roberta L


    In Darwin's Sacred Cause, Adrian Desmond and James Moore contend that "Darwin would put his utmost into sexual selection because the subject intrigued him, no doubt, but also for a deeper reason: the theory vindicated his lifelong commitment to human brotherhood" (2009: p. 360). Without questioning Desmond and Moore's evidence, I will raise some puzzles for their view. I will show that attention to the structure of Darwin's arguments in the Descent of Man shows that they are far from straightforward. As Desmond and Moore note, Darwin seems to have intended sexual selection in non-human animals to serve as evidence for sexual selection in humans. However, Darwin's account of sexual selection in humans was different from the canonical cases that Darwin described at great length. If explaining the origin of human races was the main reason for introducing sexual selection, and if sexual selection was a key piece of Darwin's anti-slavery arguments, then it is puzzling why Darwin would have spent so much time discussing cases that did not really support his argument for the origin of human races, and it is also puzzling that his argument for the origin of human races would be so (atypically) poor.

  16. Developing of the future: scaffolded Darwinism in societal evolution. (United States)

    Andersson, Claes; Törnberg, Anton; Törnberg, Petter


    We sympathize with the project of a synthetic approach for devising a "theory of intentional change" and agree that Darwinism should be central in such a theory. But Darwinism is not the only process of evolution that needs to be included. Evolutionary biology itself has taken such a turn recently, with the emergence of developmental evolutionary approaches.

  17. Classical system boundaries cannot be determined within quantum Darwinism (United States)

    Fields, Chris

    Multiple observers who interact with environmental encodings of the states of a macroscopic quantum system S as required by quantum Darwinism cannot demonstrate that they are jointly observing S without a joint a priori assumption of a classical boundary separating S from its environment E. Quantum Darwinism cannot, therefore, be regarded as providing a purely quantum-mechanical explanation of the "emergence" of classicality.

    The traditional approach used to study high energy beam propagation relies on the frozen field approximation. A minor modification of the frozen field approximation yields the set of equations applied to the analysis of the hose instability. These models are constrasted with the Darwin field approximation. A statement is made of the Darwin model equations relevant to the analysis of the hose instability

  19. The Creativity of Natural Selection? Part I: Darwin, Darwinism, and the Mutationists. (United States)

    Beatty, John


    This is the first of a two-part essay on the history of debates concerning the creativity of natural selection, from Darwin through the evolutionary synthesis and up to the present. Here I focus on the mid-late nineteenth century to the early twentieth, with special emphasis on early Darwinism and its critics, the self-styled "mutationists." The second part focuses on the evolutionary synthesis and some of its critics, especially the "neutralists" and "neo-mutationists." Like Stephen Gould, I consider the creativity of natural selection to be a key component of what has traditionally counted as "Darwinism." I argue that the creativity of natural selection is best understood in terms of (1) selection initiating evolutionary change, and (2) selection being responsible for the presence of the variation it acts upon, for example by directing the course of variation. I consider the respects in which both of these claims sound non-Darwinian, even though they have long been understood by supporters and critics alike to be virtually constitutive of Darwinism.

  20. Non-Markovianity hinders Quantum Darwinism (United States)

    Galve, Fernando; Zambrini, Roberta; Maniscalco, Sabrina


    We investigate Quantum Darwinism and the emergence of a classical world from the quantum one in connection with the spectral properties of the environment. We use a microscopic model of quantum environment in which, by changing a simple system parameter, we can modify the information back flow from environment into the system, and therefore its non-Markovian character. We show that the presence of memory effects hinders the emergence of classical objective reality, linking these two apparently unrelated concepts via a unique dynamical feature related to decoherence factors.

  1. Quantum Darwinism in Quantum Brownian Motion (United States)

    Blume-Kohout, Robin; Zurek, Wojciech H.


    Quantum Darwinism—the redundant encoding of information about a decohering system in its environment—was proposed to reconcile the quantum nature of our Universe with apparent classicality. We report the first study of the dynamics of quantum Darwinism in a realistic model of decoherence, quantum Brownian motion. Prepared in a highly squeezed state—a macroscopic superposition—the system leaves records whose redundancy increases rapidly with initial delocalization. Redundancy appears rapidly (on the decoherence time scale) and persists for a long time.

  3. Reconstructing Anaximander's biological model unveils a theory of evolution akin to Darwin's, though centuries before the birth of science. (United States)

    Trevisanato, Siro Igino


    Anaximander's fragments on biology report a theory of evolution, which, unlike the development of other biological systems in the ancient Aegean, is naturalistic and is not based on metaphysics. According to Anaximander, evolution affected all living beings, including humans. The first biological systems formed in an aquatic environment, and were encased in a rugged and robust envelope. Evolution progressed with modifications that enabled the formation of more dynamic biological systems. For instance, after reaching land, the robust armors around aquatic beings dried up, and became brittle, This led to the loss of the armor and the development of more mobile life forms. Anaximander's theory combines observations of animals with speculations, and as such mirrors the more famous theory of evolution by Charles Darwin expressed 24 centuries later. The poor reception received by Anaximander's model in his time, illustrates a zeitgeist that would explain the contemporary lag phase in the development of biology and, as a result, medicine, in the ancient western world.

    DARk matter WImp search with liquid xenoN (DARWIN) will be an experiment for the direct detection of dark matter using a multi-ton liquid xenon time projection chamber at its core. Its primary goal will be to explore the experimentally accessible parameter space for Weakly Interacting Massive Particles (WIMPs) in a wide mass-range, until neutrino interactions with the target become an irreducible background. The prompt scintillation light and the charge signals induced by particle interactions in the xenon will be observed by VUV sensitive, ultra-low background photosensors. Besides its excellent sensitivity to WIMPs above a mass of 5 GeV/c2, such a detector with its large mass, low-energy threshold and ultra-low background level will also be sensitive to other rare interactions. It will search for solar axions, galactic axion-like particles and the neutrinoless double-beta decay of 136Xe, as well as measure the low-energy solar neutrino flux with detect galactic supernovae. We present the concept of the DARWIN detector and discuss its physics reach, the main sources of backgrounds and the ongoing detector design and R&D efforts.

  5. Superintegrability of the Fock-Darwin system (United States)

    Drigho-Filho, E.; Kuru, Ş.; Negro, J.; Nieto, L. M.


    The Fock-Darwin system is analyzed from the point of view of its symmetry properties in the quantum and classical frameworks. The quantum Fock-Darwin system is known to have two sets of ladder operators, a fact which guarantees its solvability. We show that for rational values of the quotient of two relevant frequencies, this system is superintegrable, the quantum symmetries being responsible for the degeneracy of the energy levels. These symmetries are of higher order and close a polynomial algebra. In the classical case, the ladder operators are replaced by ladder functions and the symmetries by constants of motion. We also prove that the rational classical system is superintegrable and its trajectories are closed. The constants of motion are also generators of symmetry transformations in the phase space that have been integrated for some special cases. These transformations connect different trajectories with the same energy. The coherent states of the quantum superintegrable system are found and they reproduce the closed trajectories of the classical one.

  7. Group adaptation, formal darwinism and contextual analysis. (United States)

    Okasha, S; Paternotte, C


    We consider the question: under what circumstances can the concept of adaptation be applied to groups, rather than individuals? Gardner and Grafen (2009, J. Evol. Biol.22: 659-671) develop a novel approach to this question, building on Grafen's 'formal Darwinism' project, which defines adaptation in terms of links between evolutionary dynamics and optimization. They conclude that only clonal groups, and to a lesser extent groups in which reproductive competition is repressed, can be considered as adaptive units. We re-examine the conditions under which the selection-optimization links hold at the group level. We focus on an important distinction between two ways of understanding the links, which have different implications regarding group adaptationism. We show how the formal Darwinism approach can be reconciled with G.C. Williams' famous analysis of group adaptation, and we consider the relationships between group adaptation, the Price equation approach to multi-level selection, and the alternative approach based on contextual analysis. © 2012 The Authors.

    Charles S. Peirce (1839-1914) was, perhaps, first and foremost a practising or experimental scientist. However, Peirce was also a philosopher, and to him the relation between science and metaphysics was intimate. Peirce not only wanted to develop a metaphysical system consistent with the important...... scientific results and conceptions of his time, but also, like Immanuel Kant, to set metaphysics on the path of a science. This collection of articles investigates central themes and difficulties in the metaphysics of Peirce - some of the articles clarify aspects of his metaphysics, others also show...

I will try to show that typological concept defines species as fixed, immutable entities. After this, I will consider some passages of Origin of Species in the attempt to characterize Darwinian species as populations that may be modified, through natural processes, into new species. Besides, I will present the biological concept of species, trying to discuss problems of not making distinctions between species as classes and species as concrete individuals. Then, I will point out some different definitions, alternative to the biological concept. Finally, I will delineate some consequences of species definition discussion to own human species (Homo sapiens

  12. The ongoing evolution of humanness: perspectives from Darwin to de Chardin

    Directory of Open Access Journals (Sweden)

    J. S. Buckeridge


    Full Text Available The nature of humanness is discussed from observations made by Aristotle in 4th-century Greece, through to those of Charles Darwin, Teilhard de Chardin and William Shakespeare. Attempts to define humanness upon a narrow range of criteria, as some have tried, is argued as flawed, for humanness is more elusive than a single or a few demonstrated phenomena. The path that Darwin pursued in determining the place of humans in nature in his book The Descent of Man, and Selection in Relation to Sex is assessed from a 19thcentury perspective; the difficulties he faced, both personally and with the broader public, are reviewed and then evaluated in a modern context. Darwin’s thesis adheres to scientific principles, and is debated, defended and later verified on these principles. This is somewhat at variance to the approach adopted by the priest-scientist de Chardin a century later in his major work, The Phenomenon of Man—in which an attempt is made to reconcile a deep Christian faith with science. De Chardin scores well from a theological viewpoint, but fails on scientific grounds as his thesis moves beyond the realms of empiricism into mysticism. Surprisingly, de Chardin’s predicament of a future wherein human evolution enters a new stage of consciousness through the noosphere (an invisible layer of thought encompassing the globe has been partially realised through the worldwide web, although the nature of the web is almost certainly not what de Chardin might have anticipated, or desired. Science too fails to answer all, particularly the nature of God. Darwin considered the Creator in several of his works and does not dismiss the concept of a farseeing deity, although we are left with the notion that he died agnostic. Humanness is derived from an elevated moral code and this is reflected in our arts, particularly literature, wherein we may temporally reflect upon quintessential human traits such as mercy. However, expression of the arts is only

    My friend and colleague, Charles Hyder, was a true physicist with a sound intuitive grasp of fundamentals in modern physics and the underlying mathematics. I admired his knowledge of the history of modern physics and quantum mechanics when we discussed contemporary problems in interpreting solar observations. He had the ability to present his ideas clearly and persuasively to both students and his colleagues. His insatiable curiosity about life in general led him to consider the effects of nuclear weapons development on the human race. Appreciation of the biological effects of radioactive materials produced in the course of weapons and power reactor development led him to a more public career beyond traditional research. Charles Hyder was born April 18, 1930 in Albuquerque, New Mexico. He graduated from Albuquerque High School and served in the Air Force during the Korean War. He received a BS and MS in physics from the University of New Mexico (1958, 1960) and a PhD in astrogeophysics at the University of Colorado (1964). His positions included the Department of Astronomy and Institute of Geophysics at UCLA (1964-65), Sacramento Peak Solar Observatory (1965-1970) and the Goddard Space Flight Center (1970-1977). He also taught at the University of New Mexico (1970-1977) and was active on the Solar Maximum Mission science team (1970-1977, 1980-1984). He was married twice with both marriages ending in divorce. He and his first wife Ann had three children (Paul, Roxanne and Querida) and he and his second wife Laurie had a son Niels. Charles Hyder's professional career in solar physics began in 1961 during his graduate studies at the Department of AstroGeophysics of the University of Colorado and continued until 1983 when he chose to follow his convictions to expose the threat of nuclear proliferation. His early research was in the study of the quantum mechanics of polarized light produced in the presence of magnetic fields. Application of this work to interpretation

  14. Quantum Darwinism in a Mixed Environment (United States)

    Zwolak, Michael; Quan, H. T.; Zurek, Wojciech H.


    Quantum Darwinism recognizes that we—the observers—acquire our information about the “systems of interest” indirectly from their imprints on the environment. Here, we show that information about a system can be acquired from a mixed-state, or hazy, environment, but the storage capacity of an environment fragment is suppressed by its initial entropy. In the case of good decoherence, the mutual information between the system and the fragment is given solely by the fragment’s entropy increase. For fairly mixed environments, this means a reduction by a factor 1-h, where h is the haziness of the environment, i.e., the initial entropy of an environment qubit. Thus, even such hazy environments eventually reveal the state of the system, although now the intercepted environment fragment must be larger by ˜(1-h)-1 to gain the same information about the system.

  15. Freud, Darwin, and the holding environment. (United States)

    Brockman, Richard


    Freud's hypothesis of the neonate, derived from the data of adult psychoneurotic patients, was of a supremely narcissistic being who lived in a dreamlike state of hallucinatory satisfaction. A corollary hypothesis was that the neonate's drive to attach was learned and emerged only after the failure of wish fulfillment. These hypotheses provided the ground for Freud's theories of regression, dream, primary process, and pleasure principle. Darwin's data of the neonate, collected from his observations of a variety of mammals, led him to the conclusion that attachment in mammals is innate. Until 1969 and the work of John Bowlby, psychoanalytic thinking faithfully followed Freud. If psychoanalysis is to survive, then it must attach itself to data and discard any theories that are based on unproveable hypotheses, even if those hypotheses are Freud's.

  16. Empathy's purity, sympathy's complexities; De Waal, Darwin and Adam Smith. (United States)

    van der Weele, Cor


    Frans de Waal's view that empathy is at the basis of morality directly seems to build on Darwin, who considered sympathy as the crucial instinct. Yet when we look closer, their understanding of the central social instinct differs considerably. De Waal sees our deeply ingrained tendency to sympathize (or rather: empathize) with others as the good side of our morally dualistic nature. For Darwin, sympathizing was not the whole story of the "workings of sympathy"; the (selfish) need to receive sympathy played just as central a role in the complex roads from sympathy to morality. Darwin's understanding of sympathy stems from Adam Smith, who argued that the presence of morally impure motives should not be a reason for cynicism about morality. I suggest that De Waal's approach could benefit from a more thorough alignment with the analysis of the workings of sympathy in the work of Darwin and Adam Smith.

  17. Darwin at Orchis Bank: Selection after the Origin. (United States)

    Tabb, Kathryn


    Darwin's first publication after the Origin of Species was a volume on orchids that expanded on the theory of adaptation through natural selection introduced in his opus. Here I argue that On the Various Contrivances by which British and Foreign Orchids are Fertilised by Insects (1862) is not merely an empirical confirmation of his theory. In response to immediate criticisms of his metaphor of natural selection, Darwin uses Orchids to present adaptation as the result of innumerable natural laws, rather than discrete acts analogous to conscious choices. The means of selection among polliniferous plants cannot be neatly classed under the Origin's categories of artificial, natural, or sexual selection. Along with Darwin's exploration of sexual selection in his later works, Orchids serves to undo the restrictive metaphor so firmly established by the Origin and to win over those of Darwin's contemporaries who were committed advocates of natural law but suspicious of evolution by natural selection.

  18. Darwin Core: An Evolving Community-Developed Biodiversity Data Standard (United States)

    Wieczorek, John; Bloom, David; Guralnick, Robert; Blum, Stan; Döring, Markus; Giovanni, Renato; Robertson, Tim; Vieglais, David


    Biodiversity data derive from myriad sources stored in various formats on many distinct hardware and software platforms. An essential step towards understanding global patterns of biodiversity is to provide a standardized view of these heterogeneous data sources to improve interoperability. Fundamental to this advance are definitions of common terms. This paper describes the evolution and development of Darwin Core, a data standard for publishing and integrating biodiversity information. We focus on the categories of terms that define the standard, differences between simple and relational Darwin Core, how the standard has been implemented, and the community processes that are essential for maintenance and growth of the standard. We present case-study extensions of the Darwin Core into new research communities, including metagenomics and genetic resources. We close by showing how Darwin Core records are integrated to create new knowledge products documenting species distributions and changes due to environmental perturbations. PMID:22238640

  19. Foreign bodies; or, how did Darwin invent the symptom? (United States)

    Rowlinson, Matthew


    Beginning with a discussion of the sources in Darwin's writing for Freud's theory of the hysterical symptom, this essay proceeds to a symptomatic reading of Darwin himself. With reference to "The Origin of Species," "The Descent of Man," and "The Expression of the Emotions," this essay shows that Darwin's theories of involuntary expressive behavior and of aesthetic preference in sexual selection are linked by their role in his understanding of racial difference and also by their reliance on the idea that learned habits can be inherited as instincts, a view often identified with Lamarck. They are thus at once theories of the foreign body and theories that appear as foreigners within the body of Darwin's work.

  1. Darwin and the origin of life: public versus private science. (United States)

    Strick, James E


    In the first twenty years after the publication of Darwin's On the Origin of Species, an intense debate took place within the ranks of Darwin's supporters over exactly what his theory implied about the means by which the original living organism formed on Earth. Many supporters of evolutionary science also supported the doctrine of spontaneous generation: life forming from nonliving material not just once but many times up to the present day. Darwin was ambivalent on this topic. He feared its explosive potential to drive away liberal-minded Christians who might otherwise be supporters. His ambivalent wording created still more confusion, both among friends and foes, about what Darwin actually believed about the origin of life. A famous lecture by Thomas H. Huxley in 1870 set forth what later became the 'party line' Darwinian position on the subject.

  2. Electron billiards: einselection and quantum Darwinism

    International Nuclear Information System (INIS)

    Brunner, R.; Meisels, R.; Kuchar, F.; Akis, R.; Ferry, D.K.


    Full text: The measurement of open quantum systems has been a main topic since the advent of quantum theory. It is a basic ingredient in quantum information processing. Here, the border where the two worlds of classical and quantum mechanics meet is of significant importance due to the problem of measurement. It has been shown by Zurek that in an open system the environment imposes so-called superselection rules leading to environment-induced superselection (einselection). This means that a set of preferred states (pointer states) survive the coupling with the environment. These pointer states are characterized by their robustness and their ability to create offspring. This ability to advertise information about themselves makes it possible for different observers to measure the same information. The natural promotion of certain information in a quantum system is known as quantum Darwinism. The 'fitness' in the Darwinian sense of the selected states is essentially a measure of their classicality. That is in order to measure a quantum system objectively a system has to be designed where the transition between the classical and quantum world is observable. In this respect we show by a combination of experiment and calculation that an array of electron billiards (open quantum dots) is very well suited. We demonstrate that einselection takes place in electron billiards and a set of pointer states arises. We illustrate that beside the 'regular' (single dot) pointer states a new type of einselected states arise when two or more quantum dots are coupled together and to the environment. This new type of states can not be represented by a linear combination of pointer states of the individual dots. Finally, we discuss the propensity of the new type of einselected states to make offspring in order to see if quantum Darwinism is in action in the array of electron billiards.(author)

  3. [Darwinism as a constraint of ecological pluralism]. (United States)

    Giliarov, A M


    In his respond to critical remarks of Mirkin (2003), the author claims that pluralism in ecology is not only its strength but also a weakness. Contemporary ecology became less pluralistic and this can be considered as good sign of maturing science. Ecological pluralism can be exemplified by the coexistence in 1920-30s of two different approaches to plant community: that of Frederic Clements in USA and that of Josias Braun-Blanquet in France. However the way to progress in this branch of ecology was paved rather by heretical ideas of Henry Gleason in USA and Ramensky in Russia (both authors independently developed non-holistic view of community as an assemblage of individualistically distributed species) than by "peaceful" coexistence of well-established schools, representatives of which tried not to interfere into argumentation of each other. Notable success in ecology of last decades was connected with several new methodologies, e.g. macroecology that concerned large scale of space and time. However Darwinism in its attempt to explain the order of nature referring to its origin remains the most universal and fruitful methodology of ecology. The success of Darwinism in ecology is understandable because this generalizing theory is based on the same universal principles that underlie the survival of any population. Ecologists and evolutionary biologists trying to understand various natural patterns actually deal with the same fundamental laws, i.e. exponential population growth, limitation of this growth by resource shortage and/or press of predators, the existence of individual variability in survival, etc.

    Full Text Available This paper describes the types of irony used by Charles Dickens in his notable early work, Oliver Twist, as well as the reasons the irony was chosen. As a figurative language, irony is utilized to express one’s complex feelings without truly saying them. In Oliver Twist, Dickens brought the readers some real social issues wrapped in dark, deep written expressions of irony uttered by the characters of his novel. Undoubtedly, the novel had left an impact to the British society at the time. The irony Dickens displayed here includes verbal, situational, and dramatic irony. His choice of irony made sense as he intended to criticize the English Poor Laws and to touch the public sentiment. He wanted to let the readers go beyond what was literally written and once they discovered what the truth was, they would eventually understand Dickens’ purposes.

  8. Life in Darwin's dust: intercontinental transport and survival of microbes in the nineteenth century. (United States)

    Gorbushina, Anna A; Kort, Renate; Schulte, Anette; Lazarus, David; Schnetger, Bernhard; Brumsack, Hans-Jürgen; Broughton, William J; Favet, Jocelyne


    Charles Darwin, like others before him, collected aeolian dust over the Atlantic Ocean and sent it to Christian Gottfried Ehrenberg in Berlin. Ehrenberg's collection is now housed in the Museum of Natural History and contains specimens that were gathered at the onset of the Industrial Revolution. Geochemical analyses of this resource indicated that dust collected over the Atlantic in 1838 originated from the Western Sahara, while molecular-microbiological methods demonstrated the presence of many viable microbes. Older samples sent to Ehrenberg from Barbados almost two centuries ago also contained numbers of cultivable bacteria and fungi. Many diverse ascomycetes, and eubacteria were found. Scanning electron microscopy and cultivation suggested that Bacillus megaterium, a common soil bacterium, was attached to historic sand grains, and it was inoculated onto dry sand along with a non-spore-forming control, the Gram-negative soil bacterium Rhizobium sp. NGR234. On sand B. megaterium quickly developed spores, which survived for extended periods and even though the numbers of NGR234 steadily declined, they were still considerable after months of incubation. Thus, microbes that adhere to Saharan dust can live for centuries and easily survive transport across the Atlantic.

  9. Botanical smuts and hermaphrodites: Lydia Becker, Darwin's botany, and education reform. (United States)

    Gianquitto, Tina


    In 1868, Lydia Becker (1827-1890), the renowned Manchester suffragist, announced in a talk before the British Association for the Advancement of Science that the mind had no sex. A year later, she presented original botanical research at the BAAS, contending that a parasitic fungus forced normally single-sex female flowers of Lychnis diurna to develop stamens and become hermaphroditic. This essay uncovers the complex relationship between Lydia Becker's botanical research and her stance on women's rights by investigating how her interest in evolutionary theory, as well as her correspondence with Charles Darwin, critically informed her reform agendas by providing her with a new vocabulary for advocating for equality. One of the facts that Becker took away from her work on Lychnis was that even supposedly fixed, dichotomous categories such as biological sex became unfocused under the evolutionary lens. The details of evolutionary theory, from specific arguments on structural adaptations to more encompassing theories on heredity (i.e., pangenesis), informed Becker's understanding of human physiology. At the same time, Becker's belief in the fundamental equality of the sexes enabled her to perceive the distinction between inherent, biological differences and culturally contingent ones. She applied biological principles to social constructs as she asked: Do analogous evolutionary forces act on humans?

  11. Lower Charles River Bathymetry: 108 Years of Fresh Water (United States)

    Yoder, M.; Sacarny, M.


    The Lower Charles River is a heavily utilized urban river that runs between Cambridge and Boston in Massachusetts. The recreational usage of the river is dependent on adequate water depths, but there have been no definitive prior studies on the sedimentation rate of the Lower Charles River. The river transitioned from tidal to a freshwater basin in 1908 due to the construction of the (old) Charles River Dam. Water surface height on the Lower Charles River is maintained within ±1 foot through controlled discharge at the new Charles River Dam. The current study area for historical comparisons is from the old Charles River Dam to the Boston University Bridge. This study conducted a bathymetric survey of the Lower Charles River, digitized three prior surveys in the study area, calculated volumes and depth distributions for each survey, and estimated sedimentation rates from fits to the volumes over time. The oldest chart digitized was produced in 1902 during dam construction deliberations. The average sedimentation rate is estimated as 5-10 mm/year, which implies 1.8-3.5 feet sedimentation since 1908. Sedimentation rates and distributions are necessary to develop comprehensive management plans for the river and there is evidence to suggest that sedimentation rates in the shallow upstream areas are higher than the inferred rates in the study area.

  13. Quantum Darwinism in an Everyday Environment: Huge Redundancy in Scattered Photons (United States)

    Riedel, Charles; Zurek, Wojciech


    We study quantum Darwinism---the redundant recording of information about the preferred states of a decohering system by its environment---for an object illuminated by a blackbody. In the cases of point-source, small disk, and isotropic illumination, we calculate the quantum mutual information between the object and its photon environment. We demonstrate that this realistic model exhibits fast and extensive proliferation of information about the object into the environment and results in redundancies orders of magnitude larger than the exactly soluble models considered to date. We also demonstrate a reduced ability to create records as initial environmental mixedness increases, in agreement with previous studies. This research is supported by the U.S. Department of Energy through the LANL/LDRD program and, in part, by the Foundational Questions Institute (FQXi).

    Full Text Available Darwin and his transformism is the most serious challenge to the religious faith of the Church, initial being challenged the presence and God’s creative work in the living universe of the nature, and finally to challenge the existence of God as the Creator, being replaced by an eternal matters and by a blind and random natural process called natural selection. Darwinian theory proposes a dangerous road that starts from deism – with Anglican theistic accents – accepted in his time to an agnosticism and an atheism worst to strike materialism that have an ideological origins placing the foundations of ateization process of many generations starting with modernism, postmodernism and until today.

  15. Charles J. Pedersen's legacy to chemistry. (United States)

    Izatt, Reed M


    The serendipitous discovery in 1961 of dibenzo-18-crown-6 by Charles J. Pedersen marked the beginning of research on cyclic polyether macrocyclic compounds. These compounds have a remarkably selective affinity for certain metal ions and provide a framework for studying molecular recognition processes. Pedersen's work excited much interest in the scientific community and fueled important advances in macrocyclic and supramolecular chemistry. Born in Korea of a Japanese mother and a Norwegian engineer father, he was educated in Japan and later graduated from the University of Dayton (BS, chemical engineering) and Massachusetts Institute of Technology (MS, chemistry). He worked at du Pont for 42 years as a research chemist. His research talent at du Pont earned him an appointment as a Research Associate allowing him to pursue research as he chose. This freedom served him well making it possible for him to devote all his efforts following his discovery of dibenzo-18-crown-6 until his retirement to synthesis of cyclic polyethers and evaluation of their metal ion complexation properties. His influence on macrocyclic and supramolecular chemistry has been pervasive. He was co-recipient of the 1987 Nobel Prize in chemistry for development and use of molecules with structure-specific interactions of high selectivity. The year 2017 marks the fiftieth anniversary of the publication of his first paper describing his synthesis of over 50 crown ethers.

  16. Charles Bachman Moore (1920-2010) (United States)

    Winn, William; Krehbiel, Paul


    Charles B. Moore passed away 2 March 2010 at the age of 89, following a long and varied scientific career in meteorology and the atmospheric sciences. He will be remembered best for his substantial contributions in the field of atmospheric electricity and for the students and faculty he guided as chairman of Langmuir Laboratory for Atmospheric Research and professor of physics at the New Mexico Institute of Mining and Technology. He possessed a unique sense of humor and an excellent memory that served as a reservoir of scientific and historical knowledge. Like many of his generation, Charlie's career was profoundly influenced by the Second World War. Following Pearl Harbor, he interrupted his undergraduate studies in chemical engineering at Georgia Institute of Technology to enlist in the Army Air Corps, where he became the chief weather equipment officer in the 10th Weather Squadron, setting up and operating remote meteorological stations behind enemy lines in the China-Burma-India theater. He served with distinction alongside Athelstan Spilhaus Sr., who had been one of Charlie's instructors in the Army meteorology program.

    Full Text Available RESUMEN   Darwin propuso en 1871 que preferiría descender de un mono que de los “salvajes”. El mono es un babuino hamadryas que, en un relato de Brehm, salva a un infante de una jauría. Los “salvajes” son los fueguinos a los que visitó en los años 1830. ¿Por qué Darwin fue tan buen observador del comportamiento animal y por qué no dudo discernir en qué consistía la sociedad de cazadores-recolectores de los cuatro grupos de Tierra del Fuego?. Esto es lo que tratamos de dilucidar en este trabajo.   Palabras clave: Darwin, fueguinos, hamadryas, altruismo, egoísmo.

  20. Random unitary evolution model of quantum Darwinism with pure decoherence (United States)

    Balanesković, Nenad


    We study the behavior of Quantum Darwinism [W.H. Zurek, Nat. Phys. 5, 181 (2009)] within the iterative, random unitary operations qubit-model of pure decoherence [J. Novotný, G. Alber, I. Jex, New J. Phys. 13, 053052 (2011)]. We conclude that Quantum Darwinism, which describes the quantum mechanical evolution of an open system S from the point of view of its environment E, is not a generic phenomenon, but depends on the specific form of input states and on the type of S-E-interactions. Furthermore, we show that within the random unitary model the concept of Quantum Darwinism enables one to explicitly construct and specify artificial input states of environment E that allow to store information about an open system S of interest with maximal efficiency.

  1. Le Flaubert de Charles Du Bos

    Jacques Neefs


    Full Text Available Charles Du Bos a porté une attention constante à l’œuvre de Flaubert (à l’exclusion de Bouvard et Pécuchet qui semble ne pas exister pour lui, à Madame Bovary et à L’Éducation sentimentale en particulier. La mise en relation de son étude : « Sur le milieu intérieur chez Flaubert », écrite en 1921, avec des textes du Journal de 1923 et de 1937, les rapprochements avec Gogol, Thomas Hardy, Tolstoï, Baudelaire, Henry James qui traversent les écrits de Du Bos, permettent de suivre ce que celui-ci décrit comme « l’expérience spirituelle » d’une matérialité comprise dans la conquête de la triple exigence du Beau, du Vivant et du Vrai. Du Bos décèle la force de l’œuvre de Flaubert dans la « disproportion » du style, et dans la puissance d’absorption qui fait la densité de cette prose, et qui désigne un extraordinaire travail de conversion. L’obscure expérience spirituelle ainsi poursuivie est celle d’un absolu de l’art, expérience paradoxale d’un « mystique qui ne croit à rien » (comme se désignait Flaubert lui-même, que le critique lie à une interrogation sur sa propre conversion.Charles Du Bos devoted an unflagging attention to Flaubert’s work (except for Bouvard et Pécuchet, which, apparently, according to him did not exist, to Madame Bovary and in particular L’Éducation sentimentale. The connection between his essay “Sur le milieu intérieur chez Flaubert”, written in 1921, and extracts from his Journal, from 1923 to 1937, the comparisons with Gogol, Thomas Hardy, Tolstoy, Baudelaire, and Henry James that run through the writings of Du Bos, allow us to follow what he terms “the spiritual experience” of a materiality encompassed in the conquest of the triple demand of the Beautiful, the Living, the Truth. Du Bos detects the power of Flaubert’s work in the “disproportion” of his style, and the power of absorption that forms the density of his prose, showing an

  2. Dinosaurs in the year of Darwin. (United States)

    Dodson, Peter


    This special issue of The Anatomical Record explores the recent advances in the functional morphology and paleobiology of dinosaurs. Although Darwin did not study dinosaurs because paleontology was in its infancy a century and half ago, he considered both paleontology and anatomy as essential subjects for establishing the validity of evolution. The study of dinosaurs constitutes a vigorous subdiscipline within vertebrate paleontology, and anatomists and evolutionary functional morphologists constitute an especially creative subgroup within dinosaur paleontology. The collection of 17 papers presented in this issue encompass cranial anatomy, postcranial anatomy, and paleobiology of dinosaurs and other archosaurs. Soft tissue subjects include studies of brain structure, jaw adductor muscles, and keratinous appendages of the skull. Taxonomically, it includes four papers with a focus on theropods, including Tyrannosaurus, five papers dealing with ceratopsians, three papers on hadrosaurs, and one on ankylosaurs. Modern anatomical techniques such as CT scanning, finite element analysis, and high resolution histology are emphasized. The visual presentation of results of these studies is spectacular. Results include the first-ever life history table of a plant-eating dinosaur; a determination of the head orientation of Tyrannosaurus and its relatives based on interpretation of the semicircular canals. The claws of Velociraptor appear to best adapted for tree climbing, but not for horrific predatory activities. Pachyrhinosaurus evidently used its massive head for head butting. The tail club of the armored dinosaur Euoplocephalus had the structural integrity to be used as a weapon. The pages abound with insights such as these. Dinosaurs once dead for millions of years live again! (c) 2009 Wiley-Liss, Inc.

  3. Is chytridiomycosis driving Darwin's frogs to extinction?

    Directory of Open Access Journals (Sweden)

    Claudio Soto-Azat

    Full Text Available Darwin's frogs (Rhinoderma darwinii and R. rufum are two species of mouth brooding frogs from Chile and Argentina that have experienced marked population declines. Rhinoderma rufum has not been found in the wild since 1980. We investigated historical and current evidence of Batrachochytrium dendrobatidis (Bd infection in Rhinoderma spp. to determine whether chytridiomycosis is implicated in the population declines of these species. Archived and live specimens of Rhinoderma spp., sympatric amphibians and amphibians at sites where Rhinoderma sp. had recently gone extinct were examined for Bd infection using quantitative real-time PCR. Six (0.9% of 662 archived anurans tested positive for Bd (4/289 R. darwinii; 1/266 R. rufum and 1/107 other anurans, all of which had been collected between 1970 and 1978. An overall Bd-infection prevalence of 12.5% was obtained from 797 swabs taken from 369 extant individuals of R. darwinii and 428 individuals representing 18 other species of anurans found at sites with current and recent presence of the two Rhinoderma species. In extant R. darwinii, Bd-infection prevalence (1.9% was significantly lower than that found in other anurans (7.3%. The prevalence of infection (30% in other amphibian species was significantly higher in sites where either Rhinoderma spp. had become extinct or was experiencing severe population declines than in sites where there had been no apparent decline (3.0%; x(2 = 106.407, P<0.001. This is the first report of widespread Bd presence in Chile and our results are consistent with Rhinoderma spp. declines being due to Bd infection, although additional field and laboratory investigations are required to investigate this further.

  16. Darwin, Veblen and the problem of causality in economics. (United States)

    Hodgson, G M


    This article discusses some of the ways in which Darwinism has influenced a small minority of economists. It is argued that Darwinism involves a philosophical as well as a theoretical doctrine. Despite claims to the contrary, the uses of analogies to Darwinian natural selection theory are highly limited in economics. Exceptions include Thorstein Veblen, Richard Nelson, and Sidney Winter. At the philosophical level, one of the key features of Darwinism is its notion of detailed understanding in terms of chains of cause and effect. This issue is discussed in the context of the problem of causality in social theory. At least in Darwinian terms, the prevailing causal dualism--of intentional and mechanical causality--in the social sciences is found wanting. Once again, Veblen was the first economist to understand the implications for economics of Darwinism at this philosophical level. For Veblen, it was related to his notion of 'cumulative causation'. The article concludes with a discussion of the problems and potential of this Veblenian position.

  18. BOOK REVIEW: Jean-Charles Houzeau et son temps (United States)

    Sterken, C.; Verhas, P.


    This is a wonderful book. It describes the life and work of Belgian astronomer Jean-Charles Houzeau (1820-1888) and, as the last three words of the title indicate, it has a broader focus including the social, industrial and scientific context of the second part of the 19th century. This is set in a very broad international social context including social revolutions in Belgium and France, and the abolition of slavery in the United States. The biography clearly shows that this hard-working man was driven by science and justice, by individualism and generosity, by humor and sentiment. The book is divided in four parts, each part is placed in its own historical context. The first part "The apprentice, the master and his disciples" describes Houzeau's childhood and young years, his early scientific career at the Observatory in Brussels, and his relationship with Adolphe Quetelet. The evolution of this relationship is very well documented: the turbulent revolutionary Houzeau versus cool, moderated and diplomatic royalist Quetelet, the observer versus the mathematician theorist. But both were very dedicated teachers: Quetelet established public courses and after the Revolution of 1830 he contributed to the foundation of the University of Brussels; Houzeau was the peripatetic teacher wherever place he was, also after his return to Belgium. The second part is "The politician" and deals with Houzeau's political ideas and revolutionary attitudes and their consequences. His revolutionary ideas, though, were not confined to politics only: he also severely criticised the paucity of high-precision observations collected at the Royal Observatory in his days. Because he participated at revolutionary meetings, Houzeau was fired from his position at the Observatory by the Minister of Interior Affairs Charles Rogier. Thus started his peripathetic life, covering observational work in astronomy, geography, geodesy and natural sciences in many places in Belgium and abroad. The third

  9. Generic emergence of classical features in quantum Darwinism (United States)

    Brandão, Fernando G. S. L.; Piani, Marco; Horodecki, Paweł


    Quantum Darwinism posits that only specific information about a quantum system that is redundantly proliferated to many parts of its environment becomes accessible and objective, leading to the emergence of classical reality. However, it is not clear under what conditions this mechanism holds true. Here we prove that the emergence of classical features along the lines of quantum Darwinism is a general feature of any quantum dynamics: observers who acquire information indirectly through the environment have effective access at most to classical information about one and the same measurement of the quantum system. Our analysis does not rely on a strict conceptual splitting between a system-of-interest and its environment, and allows one to interpret any system as part of the environment of any other system. Finally, our approach leads to a full operational characterization of quantum discord in terms of local redistribution of correlations.

  10. Relativistic quantum Darwinism in Dirac fermion and graphene systems (United States)

    Ni, Xuan; Huang, Liang; Lai, Ying-Cheng; Pecora, Louis


    We solve the Dirac equation in two spatial dimensions in the setting of resonant tunneling, where the system consists of two symmetric cavities connected by a finite potential barrier. The shape of the cavities can be chosen to yield both regular and chaotic dynamics in the classical limit. We find that certain pointer states about classical periodic orbits can exist, which are signatures of relativistic quantum Darwinism (RQD). These localized states suppress quantum tunneling, and the effect becomes less severe as the underlying classical dynamics in the cavity is chaotic, leading to regularization of quantum tunneling. Qualitatively similar phenomena have been observed in graphene. A physical theory is developed to explain relativistic quantum Darwinism and its effects based on the spectrum of complex eigenenergies of the non-Hermitian Hamiltonian describing the open cavity system.

  13. Why Darwin would have loved evolutionary game theory. (United States)

    Brown, Joel S


    Humans have marvelled at the fit of form and function, the way organisms' traits seem remarkably suited to their lifestyles and ecologies. While natural selection provides the scientific basis for the fit of form and function, Darwin found certain adaptations vexing or particularly intriguing: sex ratios, sexual selection and altruism. The logic behind these adaptations resides in frequency-dependent selection where the value of a given heritable phenotype (i.e. strategy) to an individual depends upon the strategies of others. Game theory is a branch of mathematics that is uniquely suited to solving such puzzles. While game theoretic thinking enters into Darwin's arguments and those of evolutionists through much of the twentieth century, the tools of evolutionary game theory were not available to Darwin or most evolutionists until the 1970s, and its full scope has only unfolded in the last three decades. As a consequence, game theory is applied and appreciated rather spottily. Game theory not only applies to matrix games and social games, it also applies to speciation, macroevolution and perhaps even to cancer. I assert that life and natural selection are a game, and that game theory is the appropriate logic for framing and understanding adaptations. Its scope can include behaviours within species, state-dependent strategies (such as male, female and so much more), speciation and coevolution, and expands beyond microevolution to macroevolution. Game theory clarifies aspects of ecological and evolutionary stability in ways useful to understanding eco-evolutionary dynamics, niche construction and ecosystem engineering. In short, I would like to think that Darwin would have found game theory uniquely useful for his theory of natural selection. Let us see why this is so. © 2016 The Author(s).

  3. The DARWIN mission: Search for extra-solar planets (United States)

    Kaltenegger, L.; Fridlund, M.

    The direct detection of a planet close to its parent star is challenging because the signal detected from the parent star is between 109 and 106 times brighter than the signal of a planet in the visual and IR respectively. Future space based missions like DARWIN and TPF concentrate on the region between 6μ m to 18μ m, a region that contains the CO2, H2O, O3 spectral features of the atmosphere. The presence or absence of these spectral features would indicate similarities or differences with the atmosphere of telluric planets. The Infra Red Space Interferometer DARWIN is an integral part of ESA's Cosmic Vision 2020 plan, intended for a launch towards the middle of next decade. It is constructed around the new technique of `nulling interferometry', which exploits the wave nature of light to extinguish light from an on-axis bright object (the central star in this case), while at the same time light from a nearby source (the planet) is enhanced. An overview and update of the science of the DARWIN mission is given.

  4. Aesthetic evolution by mate choice: Darwin's really dangerous idea. (United States)

    Prum, Richard O


    Darwin proposed an explicitly aesthetic theory of sexual selection in which he described mate preferences as a 'taste for the beautiful', an 'aesthetic capacity', etc. These statements were not merely colourful Victorian mannerisms, but explicit expressions of Darwin's hypothesis that mate preferences can evolve for arbitrarily attractive traits that do not provide any additional benefits to mate choice. In his critique of Darwin, A. R. Wallace proposed an entirely modern mechanism of mate preference evolution through the correlation of display traits with male vigour or viability, but he called this mechanism natural selection. Wallace's honest advertisement proposal was stridently anti-Darwinian and anti-aesthetic. Most modern sexual selection research relies on essentially the same Neo-Wallacean theory renamed as sexual selection. I define the process of aesthetic evolution as the evolution of a communication signal through sensory/cognitive evaluation, which is most elaborated through coevolution of the signal and its evaluation. Sensory evaluation includes the possibility that display traits do not encode information that is being assessed, but are merely preferred. A genuinely Darwinian, aesthetic theory of sexual selection requires the incorporation of the Lande-Kirkpatrick null model into sexual selection research, but also encompasses the possibility of sensory bias, good genes and direct benefits mechanisms.

  5. Evolution by epigenesis: farewell to Darwinism, neo- and otherwise. (United States)

    Balon, Eugene K


    In the last 25 years, criticism of most theories advanced by Darwin and the neo-Darwinians has increased considerably, and so did their defense. Darwinism has become an ideology, while the most significant theories of Darwin were proven unsupportable. The critics advanced other theories instead of 'natural selection' and the survival of the fittest'. 'Saltatory ontogeny' and 'epigenesis' are such new theories proposed to explain how variations in ontogeny and novelties in evolution are created. They are reviewed again in the present essay that also tries to explain how Darwinians, artificially kept dominant in academia and in granting agencies, are preventing their acceptance. Epigenesis, the mechanism of ontogenies, creates in every generation alternative variations in a saltatory way that enable the organisms to survive in the changing environments as either altricial or precocial forms. The constant production of two such forms and their survival in different environments makes it possible, over a sequence of generations, to introduce changes and establish novelties--the true phenomena of evolution. The saltatory units of evolution remain far-from-stable structures capable of self-organization and self-maintenance (autopoiesis).

  6. Mechanisms of adaptive evolution. Darwinism and Lamarckism restated. (United States)

    Aboitiz, F


    This article discusses the conceptual basis of the different mechanisms of adaptive evolution. It is argued that only two such mechanisms may conceivably exist, Lamarckism and Darwinism. Darwinism is the fundamental process generating the diversity of species. Some aspects of the gene-centered approach to Darwinism are questioned, since they do not account for the generation of biological diversity. Diversity in biological design must be explained in relation to the diversity of interactions of organisms (or other higher-level units) with their environment. This aspect is usually overlooked in gene-centered views of evolution. A variant of the gene-selectionist approach has been proposed to account for the spread of cultural traits in human societies. Alternatively, I argue that social evolution is rather driven by what I call pseudo-Lamarckian inheritance. Finally, I argue that Lamarckian and pseudo-Lamarckian inheritance are just special cases of faithful replication which are found in the development of some higher-order units, such as multicellular organisms and human societies.

  10. Environmental Foundations in Germany

    Directory of Open Access Journals (Sweden)

    Thomas Krikser


    Full Text Available Foundations in Germany were examined in the context of environmental issues. Data from environmental foundations show that there is huge difference between private and public foundations concerning financial settings. Furthermore, environment is often not the only objective and sometimes not even processed. Our analysis shows that there are different types of foundations with regard to environmental scopes and activities. Although “attractive topics” such as biodiversity and landscape conservation seem to be more important to foundations, less visible topics such as pollution prevention remain merely a “blind spot.” Together, these findings suggest that there is only a limited potential of private foundations compared with public foundations. Nevertheless, there might be an impact on environmental awareness and local sustainability.

  12. Ocean Connections with the Historic Whaling Ship Charles W. Morgan (United States)

    Whitney, M. M.


    This scientific outreach project involved the Charles W. Morgan, Mystic Seaport's historic whaling ship. We educated K-2 students, trained undergraduate and graduate students, and informed the general public about oceanographic data collection, pathways from coastal to ocean waters, and connections in marine ecosystems. I was aboard the Charles W. Morgan for the Provincetown to Stellwagen Bank leg of the historic 38th voyage in summer 2014. While at sea, our voyager team released several GPS-tracked surface drifters to reveal important flow pathways and how the Stellwagen Bank National Marine Sanctuary is connected to other ocean areas. These drifters were built by graduate and undergraduate students and the drifter artwork was designed by elementary school students. Surface currents dispersed the drifters and carried them much farther offshore than the Charles W. Morgan itself. Many drifters reached Georges Bank, another important biologically productive area. The Charles W. Morgan encountered whales for the first time in decades. Some of the food-chain connections that may explain the abundance of whales at Stellwagen bank that summer are described. This outreach project has been presented in lectures to high school teachers and the general public and also featured in an online interview, a television news story, and a newspaper article. K-2 students at an elementary school math and science day first painted drifters in advance of the voyage, viewed real-time updates in the months following drifter release, and engaged in activities illustrating ocean connectivity and marine habitats at the end of the following academic year. We aimed to convey how sensitive whales are to human activities (on land and water) and to changes in the marine environment. Successes and lessons learned will be discussed.

  16. Pursuing Darwin's curious parallel: Prospects for a science of cultural evolution. (United States)

    Mesoudi, Alex


    In the past few decades, scholars from several disciplines have pursued the curious parallel noted by Darwin between the genetic evolution of species and the cultural evolution of beliefs, skills, knowledge, languages, institutions, and other forms of socially transmitted information. Here, I review current progress in the pursuit of an evolutionary science of culture that is grounded in both biological and evolutionary theory, but also treats culture as more than a proximate mechanism that is directly controlled by genes. Both genetic and cultural evolution can be described as systems of inherited variation that change over time in response to processes such as selection, migration, and drift. Appropriate differences between genetic and cultural change are taken seriously, such as the possibility in the latter of nonrandomly guided variation or transformation, blending inheritance, and one-to-many transmission. The foundation of cultural evolution was laid in the late 20th century with population-genetic style models of cultural microevolution, and the use of phylogenetic methods to reconstruct cultural macroevolution. Since then, there have been major efforts to understand the sociocognitive mechanisms underlying cumulative cultural evolution, the consequences of demography on cultural evolution, the empirical validity of assumed social learning biases, the relative role of transformative and selective processes, and the use of quantitative phylogenetic and multilevel selection models to understand past and present dynamics of society-level change. I conclude by highlighting the interdisciplinary challenges of studying cultural evolution, including its relation to the traditional social sciences and humanities.

  18. Shells on elastic foundations

    International Nuclear Information System (INIS)

    Das, Y.C.; Kedia, K.K.


    No realistic analytical work in the area of Shells on Elastic Foundations has been reported in the literature. Various foundation models have been proposed by several authors. These models involve one or more than one parameters to characterise the foundation medium. Some of these models cannot be used to derive the basic equations governing the behaviour of shells on elastic foundations. In the present work, starting from an elastic continuum hypothesis, a mathematical model for foundation has been derived in curvilinear orthogonal coordinates by the help of principle of virtual displacements, treating one of the virtual displacements as known to satisfy certain given conditions at its edge surfaces. In this model, several foundation parameters can be considered and it can also be used for layered medium of both finite and infinite thickness. (Auth.)

  19. Darwin's goldmine is still open: variation and selection run the world (United States)

    Forterre, Patrick


    The scientific contribution of Darwin, still agonized in many religious circles, has now been recognized and celebrated by scientists from various disciplines. However, in recent years, several evolutionists have criticized Darwin as outdated, arguing that “Darwinism,” assimilated to the “tree of life,” cannot explain microbial evolution, or else was not operating in early life evolution. These critics either confuse “Darwinism” and old versions of “neo-Darwinism” or misunderstand the role of gene transfers in evolution. The core of Darwin explanation of evolution (variation/selection) remains necessary and sufficient to decipher the history of life. The enormous diversity of mechanisms underlying variations has been successfully interpreted by evolutionists in this framework and has considerably enriched the corpus of evolutionary biology without the necessity to kill the father. However, it remains for evolutionists to acknowledge interactions between cells and viruses (unknown for Darwin) as a major driving force in life evolution. PMID:22919695

  20. Quantum theory of the classical: quantum jumps, Born's Rule and objective classical reality via quantum Darwinism. (United States)

    Zurek, Wojciech Hubert


    The emergence of the classical world from the quantum substrate of our Universe is a long-standing conundrum. In this paper, I describe three insights into the transition from quantum to classical that are based on the recognition of the role of the environment. I begin with the derivation of preferred sets of states that help to define what exists-our everyday classical reality. They emerge as a result of the breaking of the unitary symmetry of the Hilbert space which happens when the unitarity of quantum evolutions encounters nonlinearities inherent in the process of amplification-of replicating information. This derivation is accomplished without the usual tools of decoherence, and accounts for the appearance of quantum jumps and the emergence of preferred pointer states consistent with those obtained via environment-induced superselection, or einselection The pointer states obtained in this way determine what can happen-define events-without appealing to Born's Rule for probabilities. Therefore, p k =| ψ k | 2 can now be deduced from the entanglement-assisted invariance, or envariance -a symmetry of entangled quantum states. With probabilities at hand, one also gains new insights into the foundations of quantum statistical physics. Moreover, one can now analyse the information flows responsible for decoherence. These information flows explain how the perception of objective classical reality arises from the quantum substrate: the effective amplification that they represent accounts for the objective existence of the einselected states of macroscopic quantum systems through the redundancy of pointer state records in their environment-through quantum Darwinism This article is part of a discussion meeting issue 'Foundations of quantum mechanics and their impact on contemporary society'. © 2018 The Author(s).

  1. The evolutionary biology of musical rhythm: was Darwin wrong?

    Directory of Open Access Journals (Sweden)

    Aniruddh D Patel


    Full Text Available In The Descent of Man, Darwin speculated that our capacity for musical rhythm reflects basic aspects of brain function broadly shared among animals. Although this remains an appealing idea, it is being challenged by modern cross-species research. This research hints that our capacity to synchronize to a beat, i.e., to move in time with a perceived pulse in a manner that is predictive and flexible across a broad range of tempi, may be shared by only a few other species. Is this really the case? If so, it would have important implications for our understanding of the evolution of human musicality.

  3. Redundant information from thermal illumination: quantum Darwinism in scattered photons

    Energy Technology Data Exchange (ETDEWEB)

    Jess Riedel, C; Zurek, Wojciech H, E-mail: [Theory Division, LANL, Los Alamos, NM 87545 (United States)


    We study quantum Darwinism, the redundant recording of information about the preferred states of a decohering system by its environment, for an object illuminated by a blackbody. We calculate the quantum mutual information between the object and its photon environment for blackbodies that cover an arbitrary section of the sky. In particular, we demonstrate that more extended sources have a reduced ability to create redundant information about the system, in agreement with previous evidence that initial mixedness of an environment slows-but does not stop-the production of records. We also show that the qualitative results are robust for more general initial states of the system.

  4. Darwinism, not mutationism, explains the design of organisms. (United States)

    Gardner, Andy


    Shapiro claims that advances in molecular genetics have undermined Darwinism, leading him to advocate mutationism. However, this extreme view is bourne out of conceptual error. He has misunderstood the distinction between gradualism and saltationism, which do not concern the rate of genetic change, but rather the emergence of complex design. And he has misunderstood the relationship between the dynamics of natural selection and the agency of individual organisms: these are not competing hypotheses, but rather alternative conceptualizations of the same phenomenon.

  6. Introduction to the special issue on Social Darwinism. (United States)

    Albee, G W


    A brief history is provided of interventions with people with emotional disorders since the 1950s. A shortage of therapists is inescapable and even successful treatment does not change incidence. But the individual defect model supports the conservative view that causes are to be found inside people, rather than in social injustice. People who are defective are to be treated as part of the medical model that is extended to cover social problems. This view is an obvious extension of Social Darwinism that has long attributed success and failure to bad genes and good genes rather than to advantaged and disadvantaged social-economic environments.

  7. Stratigraphy and paleogeographic significance of a Late Pennsylvanian to Early Permian channeled slope sequence in the Darwin Basin, southern Darwin Hills, east-central California (United States)

    Stevens, Calvin H.; Stone, Paul; Magginetti, Robert T.; Ritter, Scott M.


    The complex stratigraphy of late Paleozoic rocks in the southern Darwin Hills consists of regionally extensive Mississippian and Early to Middle Pennsylvanian rocks overlain by latest Pennsylvanian to Early Permian rocks, herein called the Darwin Hills sequence. Deposition of this latter sequence marked the beginning of the Darwin Basin. In Mississippian time, a carbonate platform prograded westward over slightly older slope deposits. In the Late Mississippian this platform was exposed to erosion and siliciclastic sediments were deposited. In Early to Middle Pennsylvanian time the area subsided, forming a west-facing ramp that was subjected to deformation and erosion in Middle or early Late Pennsylvanian time. Later this area was tilted westward and deep-water sediments were deposited on this slope. In latest Pennsylvanian to earliest Permian time, a major channel was cut through the older Pennsylvanian rocks and into the Upper Mississippian strata. This channel was gradually filled with increasingly finer grained, deep-water sediment as the area evolved into a basin floor by Early Permian (Sakmarian) time. Expansion of the Darwin Basin in Artinskian time led to a second phase of deposition represented by strata of the regionally extensive Darwin Canyon Formation. The geology in this small area thus documents tectonic events occurring during the early development of the Darwin Basin.

  13. Uplift of quaternary shorelines in eastern Patagonia: Darwin revisited (United States)

    Pedoja, Kevin; Regard, Vincent; Husson, Laurent; Martinod, Joseph; Guillaume, Benjamin; Fucks, Enrique; Iglesias, Maximiliano; Weill, Pierre


    During his journey on the Beagle, Darwin observed the uniformity in the elevation of coastal Eastern Patagonia along more than 2000 km. More than one century later, the sequences of Quaternary shorelines of eastern Patagonia have been described and their deposits dated but not yet interpreted in terms of geodynamics. Consequently, we i) mapped the repartition of the Quaternary coastal sequences in Argentinean Patagonia, ii) secured accurate altitudes of shoreline angles associated with erosional morphologies (i.e. marine terraces and notches), iii) took into account previous chrono-stratigraphical interpretations in order to calculate mean uplift rates since ~ 440 ka (MIS 11) and proposed age ranges for the higher and older features (up to ~ 180 m), and iv) focused on the Last Interglacial Maximum terrace (MIS 5e) as the best constrained marine terrace (in terms of age and altitude) in order to use it as a tectonic benchmark to quantify uplift rates along the entire passive margin of Eastern South America. Our results show that the eastern Patagonia uplift is constant through time and twice the uplift of the rest of the South American margin. We suggest that the enhanced uplift along the eastern Patagonian coast that interested Darwin during his journey around South America on the Beagle could originate from the subduction of the Chile ridge and the associated dynamic uplift.

  14. Evolution beyond neo-Darwinism: a new conceptual framework. (United States)

    Noble, Denis


    Experimental results in epigenetics and related fields of biological research show that the Modern Synthesis (neo-Darwinist) theory of evolution requires either extension or replacement. This article examines the conceptual framework of neo-Darwinism, including the concepts of 'gene', 'selfish', 'code', 'program', 'blueprint', 'book of life', 'replicator' and 'vehicle'. This form of representation is a barrier to extending or replacing existing theory as it confuses conceptual and empirical matters. These need to be clearly distinguished. In the case of the central concept of 'gene', the definition has moved all the way from describing a necessary cause (defined in terms of the inheritable phenotype itself) to an empirically testable hypothesis (in terms of causation by DNA sequences). Neo-Darwinism also privileges 'genes' in causation, whereas in multi-way networks of interactions there can be no privileged cause. An alternative conceptual framework is proposed that avoids these problems, and which is more favourable to an integrated systems view of evolution. © 2015.

  15. Temperature and Humidity Effects on Hospital Morbidity in Darwin, Australia. (United States)

    Goldie, James; Sherwood, Steven C; Green, Donna; Alexander, Lisa


    Many studies have explored the relationship between temperature and health in the context of a changing climate, but few have considered the effects of humidity, particularly in tropical locations, on human health and well-being. To investigate this potential relationship, this study assessed the main and interacting effects of daily temperature and humidity on hospital admission rates for selected heat-relevant diagnoses in Darwin, Australia. Univariate and bivariate Poisson generalized linear models were used to find statistically significant predictors and the admission rates within bins of predictors were compared to explore nonlinear effects. The analysis indicated that nighttime humidity was the most statistically significant predictor (P < 0.001), followed by daytime temperature and average daily humidity (P < 0.05). There was no evidence of a significant interaction between them or other predictors. The nighttime humidity effect appeared to be strongly nonlinear: Hot days appeared to have higher admission rates when they were preceded by high nighttime humidity. From this analysis, we suggest that heat-health policies in tropical regions similar to Darwin need to accommodate the effects of temperature and humidity at different times of day.

  16. The role of foundations: Rockefeller Foundation. (United States)

    Rockefeller, David

    The consequences of climate change and the impacts of human activity on the environment have made it clearer than ever before that we must evolve our current model of public health to better account for the inextricable link between human health and the natural systems on which it depends-creating a "public health 2.0" that builds on the innovations of the twentieth century to account for a world where humans have bypassed planetary boundaries to achieve well-being. First coined at the Rockefeller Foundation's Centennial gathering in Beijing in 2013, "Planetary Health" will factor in future health and environmental harms over present-day gains, particularly those that disproportionately affect the poor and those in developing nations. To build this new field, foundations must address the challenge of information, increasing support for research to bridge knowledge gaps on the links between economic development, natural systems, and human health.

  17. Social Darwinism: from reality to myth and from myth to reality. (United States)

    Becquemont, Daniel


    Considering the variety of contradictory definitions which have been attributed to the term in the course of more than a century, one may be tempted to admit that 'Social Darwinism' can be reduced to a social myth. But it seems nevertheless necessary to answer the question: what has been called 'Social Darwinism' for more than one century and why was the expression used in a negative way to express contradictory opinions which sometimes have nothing to do with Darwin's theory. What we still call 'Social Darwinism' is the result of a misunderstanding: the theories expressed under that phrase have little to do with the Darwinian concepts of natural selection or descent with modification. They have their origin in a pre-darwinian conception of the struggle for existence, which Darwin used in a metaphorical sense. This confusion will then appear to refer clearly to the relationship we establish between biology and society, whether biological laws are directly prolonged in society, or more or less intermingle in a close network. The issue of the definition of Social Darwinism depends obviously on the possible answers to this question, and so does the issue of redefining Darwinism at large. Copyright © 2010 Elsevier Ltd.

  18. Darwin: Dose monitoring system applicable to various radiations with wide energy ranges

    International Nuclear Information System (INIS)

    Sato, T.; Satoh, D.; Endo, A.; Yamaguchi, Y.


    A new radiation dose monitor, designated as DARWIN (Dose monitoring system Applicable to various Radiations with Wide energy ranges), has been developed for real-time monitoring of doses in workspaces and surrounding environments of high-energy accelerator facilities. DARWIN is composed of a Phoswitch-type scintillation detector, which consists of liquid organic scintillator BC501A coupled with ZnS(Ag) scintillation sheets doped with 6 Li, and a data acquisition system based on a Digital-Storage-Oscilloscope. DARWIN has the following features: (1) capable of monitoring doses from neutrons, photons and muons with energies from thermal energy to 1 GeV, 150 keV to 100 MeV and 1 MeV to 100 GeV, respectively, (2) highly sensitive with precision and (3) easy to operate with a simple graphical user-interface. The performance of DARWIN was examined experimentally in several radiation fields. The results of the experiments indicated the accuracy and wide response range of DARWIN for measuring dose rates from neutrons, photons and muons with wide energies. It was also found from the experiments that DARWIN enables us to monitor small fluctuations of neutron dose rates near the background level because of its high sensitivity. With these properties, DARWIN will be able to play a very important role for improving radiation safety in high-energy accelerator facilities. (authors)

  19. From Darwin's Origin of Species toward a theory of natural history. (United States)

    Boero, Ferdinando


    Darwin is the father of evolutionary theory because he identified evolutionary patterns and, with Natural Selection, he ascertained the exquisitely ecological ultimate processes that lead to evolution. The proximate processes of evolution he proposed, however, predated the discovery of genetics, the backbone of modern evolutionary theory. The later discovery of the laws of inheritance by Mendel and the rediscovery of Mendel in the early 20th century led to two reforms of Darwinism: Neo-Darwinism and the Modern Synthesis (and subsequent refinements). If Darwin's evolutionary thought required much refinement, his ecological insight is still very modern. In the first edition of The Origin of Species, Darwin did not use either the word "evolution" or the word "ecology". "Ecology" was not coined until after the publication of the Origin. Evolution, for him, was the origin of varieties, then species, which he referred to as well-marked varieties, whereas, instead of using ecology, he used "the economy of nature". The Origin contains a high proportion of currently accepted ecological principles. Darwin labelled himself a naturalist. His discipline (natural history) was a blend of ecology and evolution in which he investigated both the patterns and the processes that determine the organization of life. Reductionist approaches, however, often keep the two disciplines separated from each other, undermining a full understanding of natural phenomena that might be favored by blending ecology and evolution through the development of a modern Theory of Natural History based on Darwin's vision of the study of life.

  20. A Dutch Confederate: Charles Liernur Defends Slavery in America

    Directory of Open Access Journals (Sweden)

    Michael J. Douma


    Full Text Available In the 1850s and 1860s, Dutch immigrants in America struggled to square their racial views with the politics of slavery in their new country. The historiography of the Dutch world would benefit from incorporating this story, because it is often in moments of conflict when the most explicit expressions of ideology present themselves. The letters of Charles Liernur, a Dutch-born Confederate, provide a unique insight into the mind of an explicit supporter of slavery in an American context. How and why a Dutchman could defend slavery is the primary question this article addresses. Building on Liernur’s story, this article also challenges the standard view that Dutch Americans were natural opponents of slavery. Instead, they held diverse and ambiguous views, shaped in part by the circumstances of their settlement.Een Nederlandse Confederate: Charles Liernur verdedigt slavernij in AmerikaIn de jaren vijftig en zestig van de negentiende eeuw hadden Nederlandse immigranten in Amerika grote moeite een standpunt in te nemen met betrekking tot de slavernij. Een analyse daarvan lijkt van belang voor de Nederlandse geschiedschrijving, omdat ideologische overtuigingen vaak tijdens conflicten op scherpe wijze uitgedragen worden. De brieven van Charles Liernur, een Nederlandse ‘Confederate’, bieden een unieke blik op de denkwereld van eenuitgesproken voorstander van de slavernij. Hoe en waarom kon een Nederlander zo fel de slavernij verdedigen? Dat is de centrale vraag waarop dit artikel een antwoord probeert te geven. Het verhaal van Liernur laat zien dat de gangbare visie, dat Nederlandse Amerikanen van nature tegenstanders van de slavernij waren, niet klopt. Immigranten hadden veeleer uiteenlopende en ambigue meningen over slavernij, bepaald door de omstandigheden waarmee ze in hun nieuwe vaderland te maken kregen.

  1. Primary secretory otitis media in Cavalier King Charles spaniels. (United States)

    Cole, Lynette K


    Primary secretory otitis media (PSOM) is a disease that has been described in the Cavalier King Charles spaniel (CKCS). A large, bulging pars flaccida identified on otoscopic examination confirms the diagnosis. However, in many CKCS with PSOM the pars flaccida is flat, and radiographic imaging is needed to confirm the diagnosis. Current treatment for PSOM includes performing a myringotomy into the caudal-ventral quadrant of the pars tensa with subsequent flushing of the mucus out of the bulla using a video otoscope. Repeat myringotomies and flushing of the middle ear are necessary to keep the middle ear free of mucus. Copyright © 2012 Elsevier Inc. All rights reserved.

  4. Paleontology and Darwin's Theory of Evolution: The Subversive Role of Statistics at the End of the 19th Century. (United States)

    Tamborini, Marco


    This paper examines the subversive role of statistics paleontology at the end of the 19th and the beginning of the 20th centuries. In particular, I will focus on German paleontology and its relationship with statistics. I argue that in paleontology, the quantitative method was questioned and strongly limited by the first decade of the 20th century because, as its opponents noted, when the fossil record is treated statistically, it was found to generate results openly in conflict with the Darwinian theory of evolution. Essentially, statistics questions the gradual mode of evolution and the role of natural selection. The main objections to statistics were addressed during the meetings at the Kaiserlich-Königliche Geologische Reichsanstalt in Vienna in the 1880s. After having introduced the statistical treatment of the fossil record, I will use the works of Charles Léo Lesquereux (1806-1889), Joachim Barrande (1799-1833), and Henry Shaler Williams (1847-1918) to compare the objections raised in Vienna with how the statistical treatment of the data worked in practice. Furthermore, I will discuss the criticisms of Melchior Neumayr (1845-1890), one of the leading German opponents of statistical paleontology, to show why, and to what extent, statistics were questioned in Vienna. The final part of this paper considers what paleontologists can derive from a statistical notion of data: the necessity of opening a discussion about the completeness and nature of the paleontological data. The Vienna discussion about which method paleontologists should follow offers an interesting case study in order to understand the epistemic tensions within paleontology surrounding Darwin's theory as well as the variety of non-Darwinian alternatives that emerged from the statistical treatment of the fossil record at the end of the 19th century.

  5. From Darwin to Internet at the speed of light (United States)


    Data moving around the Internet are like road traffic in that a car can be driven fast down a straight road but has to slow down a great deal when changing direction at a junction. The same thing happens on information highways. Beams of light carry data along fibre-optic cables at very high speeds. When the data arrive at computers, known as servers, the servers redirect them to their final destinations. Presently, you need to convert the light signals into electricity, and that slows everything down. Electrons move at a speed of a few kilometres per second through a circuit, whereas light travels at nearly 300 000 kilometres per second. Integrated optics would leave the data as light and simply channel it through the chip, in the right direction. Scientists call this area integrated optics, referring to the integrated circuit board on which chips are mounted. Instead of miniaturised electronics, however, miniaturised optics are placed on a microchip. ESA has a strategy to enable more sophisticated searches for extra-solar planets in the future. Two planned developments rely on combining the light from such planets in a number of different telescopes. These are the Darwin mission and its precursor, the ESA/ESO Ground-based European Nulling Interferometer Experiment (GENIE). When you combine light beams, you traditionally need moving mirrors and lenses to divert the light beams to where you want them. However, if the system moves, it can break. As Malcolm Fridlund, Project Scientist for Darwin and GENIE says, “To change to integrated optics, which is much smaller and has no moving parts, would be highly desirable.” Desirable certainly, but also difficult. At present, integrated optics is a science that is far behind integrated circuit technology. For this reason, ESA is funding two studies. Astrium has been asked to study a traditional optics approach and Alcatel is investigating an integrated-optics solution. “We shall take the decision on whether GENIE will

  6. How Two Sides of the Atlantic Contributed to Understanding of the Global Oceans: Charles Yentsch and Andre Morel (United States)

    Acker, James G.


    In a few short days in September of this year, the ocean color/ocean optics community lost two of the founding members of its Hall of FameCharles Yentsch and Andre Morel. Yentsch passed away at the age of 85 on September 19, and Morel passed away on September 23 at the age of 79. It might sound clich to say that someone was instrumental to the advance of science in a particular field, but in the case of Yentsch and Morel and ocean color instrumentation, such an assessment would likely be accurate. Each mans career complimented that of the other Yentsch was one of the first to make measurements of the light field of the ocean from altitude and to advocate an instrument in space that could observe the spectrum of ocean radiance Morels theoretical underpinnings established a firm foundation for the measurements such an instrument could make, allowing their successful interpretation.

  3. Charles Olivier and the rise of meteor science

    CERN Document Server

    Taibi, Richard


    This fascinating portrait of an amateur astronomy movement tells the story of how Charles Olivier recruited a hard-working cadre of citizen scientists to rehabilitate the study of meteors. By 1936, Olivier and members of his American Meteor Society had succeeded in disproving an erroneous idea about meteor showers. Using careful observations, they restored the public’s trust in predictions about periodic showers and renewed respect for meteor astronomy among professional astronomers in the United States. Charles Olivier and his society of observers who were passionate about watching for meteors in the night sky left a major impact on the field. In addition to describing Olivier’s career and describing his struggles with competitive colleagues in a hostile scientific climate, the author provides biographies of some of the scores of women and men of all ages who aided Olivier in making shower observations, from the Leonids and Perseids and others. Half of these amateur volunteers were from 13 to 25 years of...

    Full Text Available El motivo principal para traer al arquitecto Charles E. Carré a Medellín se atribuye básicamente a la construcción de la catedral de Villanueva, en Antioquia. Monsieur Carré, como se le conoció, fue tema, nueva y tristemente, a causa de su inesperada muerte ocurrida en 1909, de las páginas de los diarios locales, quince años después de su partida de la ciudad de Medellín, que en todo momento profesó respeto y admiración y a quien "se le debe [...] el habernos mostrado que [...] el ladrillo cocido no es piedra [...], que cualquier barro cocido no es ladrillo y [...] que en artes de construir no es el renacimiento ni la última ni la mejor de las palabras". A continuación hacemos una relación cronológica de las obras de Charles Carré en Antioquia:

  5. Advertising eugenics: Charles M. Goethe's campaign to improve the race. (United States)

    Schoenl, William; Peck, Danielle


    Over the last several decades historians have shown that the eugenics movement appealed to an extraordinarily wide constituency. Far from being the brainchild of the members of any one particular political ideology, eugenics made sense to a diverse range of Americans and was promoted by professionals ranging from geneticists and physicians to politicians and economists.(1) Seduced by promises of permanent fixes to national problems, and attracted to the idea of a scientifically legitimate form of social activism, eugenics quickly grew in popularity during the first decades of the twentieth century. Charles M. Goethe, the land developer, entrepreneur, conservationist and skilled advertiser who founded the Eugenics Society of Northern California, exemplifies the broad appeal of the eugenics movement. Goethe played an active role within the American eugenics movement at its peak in the 1920s. The last president of the Eugenics Research Association,(2) he also campaigned hard against Mexican immigration to the US and he continued open support for the Nazi regime's eugenic practices into the later 1930s.(3) This article examines Goethe's eugenic vision and, drawing on his correspondence with the leading geneticist Charles Davenport, explores the relationship between academic and non-academic advocates of eugenics in America.

  6. Dublin and Irish politics in the age of Charles Lucas. (United States)

    Hill, J


    In addition to his contributions to medicine, Charles Lucas had a long career in politics, starting in the 1740s as a guild representative on the lower house of Dublin corporation, and culminating in his election to the Irish House of Commons in 1761. By examining the background in Dublin and Irish politics, this paper explores Lucas' impact on the electorate, and how it was that he was able to win a parliamentary seat in Dublin and retain it for a decade while he campaigned in support of a range of important Patriot issues. Lucas had none of the qualifications that would normally be required for a successful politician. His father held some land, but as a younger son who had to make a living, Charles was apprenticed to a Dublin apothecary. Nor did he have the political connections that might have compensated for a lack of land, wealth, or status. But Lucas possessed other advantages, notably an education that enabled him to read the city's medieval charters, identifying areas where the Dublin freemen had lost 'ancient rights', and some experience of publishing, so that he could appeal to the electorate. Lucas' remarkable political success stemmed from both local circumstances and his own personal qualities.

  10. Radiation and the regulatory landscape of neo2-Darwinism

    International Nuclear Information System (INIS)

    Rollo, C. David


    Several recently revealed features of eukaryotic genomes were not predicted by earlier evolutionary paradigms, including the relatively small number of genes, the very large amounts of non-functional code and its quarantine in heterochromatin, the remarkable conservation of many functionally important genes across relatively enormous phylogenetic distances, and the prevalence of extra-genomic information associated with chromatin structure and histone proteins. All of these emphasize a paramount role for regulatory evolution, which is further reinforced by recent perspectives highlighting even higher-order regulation governing epigenetics and development (EVO-DEVO). Modern neo 2 -Darwinism, with its emphasis on regulatory mechanisms and regulatory evolution provides new vision for understanding radiation biology, particularly because free radicals and redox states are central to many regulatory mechanisms and free radicals generated by radiation mimic and amplify endogenous signalling. This paper explores some of these aspects and their implications for low-dose radiation biology

  11. Proton radius, Darwin-Foldy term and radiative corrections

    International Nuclear Information System (INIS)

    Jentschura, U.D.


    We discuss the role of the so-called Darwin-Foldy term in the evaluation of the proton and deuteron charge radii from atomic hydrogen spectroscopy and nuclear scattering data. The question of whether this term should be included or excluded from the nuclear radius has been controversially discussed in the literature. We attempt to clarify which literature values correspond to which conventions. A detailed discussion of the conventions appears useful because a recent experiment [R. Pohl et al., Nature 466, 213 (2010)] has indicated that there is a discrepancy between the proton charge radii inferred from ordinary ('electronic') atomic hydrogen and muonic hydrogen. We also investigate the role of quantum electrodynamic radiative corrections in the determination of nuclear radii from scattering data, and propose a definition of the nuclear self energy which is compatible with the subtraction of the radiative corrections in scattering experiments.

  12. Better science and better race? Social Darwinism and Chinese eugenics. (United States)

    Chung, Yuehtsen Juliette


    This essay explores the variegated roles played by racial, eugenic, and Social Darwinist discourse in China over roughly the last century. Using Japan as a parallel for comparison, it analyzes the introduction of the term "eugenics" into Japanese and Chinese. It then locates the deployment of eugenics and Social Darwinism as counterimperial discourse in East Asia. It offers a brief history of eugenics thinking in China across the twentieth century, focusing on the Chinese eugenicist Pan Guangdan, who used race as a category of analysis yet without any sense of hierarchy. He was critically aware of the scientific basis of eugenics and helped craft the study of eugenics in China, from biology to sociology, from economics to ethnology.

  13. Response variance in functional maps: neural darwinism revisited.

    Directory of Open Access Journals (Sweden)

    Hirokazu Takahashi

    Full Text Available The mechanisms by which functional maps and map plasticity contribute to cortical computation remain controversial. Recent studies have revisited the theory of neural Darwinism to interpret the learning-induced map plasticity and neuronal heterogeneity observed in the cortex. Here, we hypothesize that the Darwinian principle provides a substrate to explain the relationship between neuron heterogeneity and cortical functional maps. We demonstrate in the rat auditory cortex that the degree of response variance is closely correlated with the size of its representational area. Further, we show that the response variance within a given population is altered through training. These results suggest that larger representational areas may help to accommodate heterogeneous populations of neurons. Thus, functional maps and map plasticity are likely to play essential roles in Darwinian computation, serving as effective, but not absolutely necessary, structures to generate diverse response properties within a neural population.

  16. Mesh-free Hamiltonian implementation of two dimensional Darwin model (United States)

    Siddi, Lorenzo; Lapenta, Giovanni; Gibbon, Paul


    A new approach to Darwin or magnetoinductive plasma simulation is presented, which combines a mesh-free field solver with a robust time-integration scheme avoiding numerical divergence errors in the solenoidal field components. The mesh-free formulation employs an efficient parallel Barnes-Hut tree algorithm to speed up the computation of fields summed directly from the particles, avoiding the necessity of divergence cleaning procedures typically required by particle-in-cell methods. The time-integration scheme employs a Hamiltonian formulation of the Lorentz force, circumventing the development of violent numerical instabilities associated with time differentiation of the vector potential. It is shown that a semi-implicit scheme converges rapidly and is robust to further numerical instabilities which can develop from a dominant contribution of the vector potential to the canonical momenta. The model is validated by various static and dynamic benchmark tests, including a simulation of the Weibel-like filamentation instability in beam-plasma interactions.

  17. Rereading Darwin. Notes for a critical history of indeterminism

    Directory of Open Access Journals (Sweden)

    Italo Scardovi


    Full Text Available On carefully re-examining the theory of natural selection, one can see in it the first nondeterministic hypothesis in the history of modern science. As such it also exemplifies the use of statistics as a modus intellegendi, as an empirical language for all phenomena which cannot be interpreted in terms of strict teleology. According to this interpretation, the work of Darwin turns the course of science towards a new way of knowing, of interpreting nature, the way that with Mendel’s Laws has given birth to a deep renewal of research in biology, and has also gradually come to characterize all modern physics starting from the statistical thermodynamics of Boltzmann.

  18. Kropotkin between Lamarck and Darwin: the impossible synthesis

    Directory of Open Access Journals (Sweden)

    Girón, Álvaro


    Full Text Available Prince P.A. Kropotkin (1842-1921 was the most important leader of revolutionary anarchism of his generation. He was also a respected explorer, geographer, and wrote a variety of books on the French Revolution, prison systems and Russian literature. However, he is better known for his contribution to the debate on Social Darwinism, exemplified by his book Mutual Aid. A Factor Evolution (1902. Actually, Kropotkin was trying to build his own brand of evolutionary Ethics: a complete socio-biology consistent with revolutionary goals. But there was a serious obstacle. The presence of the Malthusian population laws at the very core of Darwinism blocked any potential progress in this direction. Kropotkin tried to extirpate the Malthusian sting by making a critical analysis of natural selection and proposing a synthesis between Lamarck and Darwin in the 1910s.
    The aim of this article is to study the basics of the argument deployed by Kropotkin. It has been paid especial attention to the criticisms addressed to the hard heredity theory of August Weismann, and the reasons why Kropotkin’s contribution in this field has been ignored.

  19. Darwin's "Mr. Arthrobalanus": Sexual Differentiation, Evolutionary Destiny and the Expert Eye of the Beholder. (United States)

    Buchanan, Roderick D


    Darwin's Cirripedia project was an exacting exercise in systematics, as well as an encrypted study of evolution in action. Darwin had a long-standing interest and expertise in marine invertebrates and their sexual arrangements. The surprising and revealing sexual differentiation he would uncover amongst barnacles represented an important step in his understanding of the origins of sexual reproduction. But it would prove difficult to reconcile these findings with his later theorizing. Moreover, the road to discovery was hardly straightforward. Darwin was both helped and hindered by the tacit expectations generated by his transformist theorizing, and had to overcome culturally-embedded assumptions about gender and reproductive roles. Significant observational backtracking was required to correct several oversights and misapprehensions, none more so than those relating to the chronically misunderstood "Mr. Arthrobalanus." With careful attention to chronology, this paper highlights some curious and overlooked aspects of Darwin's epic project.

  1. William Keith Brooks and the naturalist's defense of Darwinism in the late-nineteenth century. (United States)

    Nash, Richard


    William Keith Brooks was an American zoologist at Johns Hopkins University from 1876 until his death in 1908. Over the course of his career, Brooks staunchly defended Darwinism, arguing for the centrality of natural selection in evolutionary theory at a time when alternative theories, such as neo-Lamarckism, grew prominent in American biology. In his book The Law of Heredity (1883), Brooks addressed problems raised by Darwin's theory of pangenesis. In modifying and developing Darwin's pangenesis, Brooks proposed a new theory of heredity that sought to avoid the pitfalls of Darwin's hypothesis. In so doing he strengthened Darwin's theory of natural selection by undermining arguments for the inheritance of acquired characteristics. In later attacks on neo-Lamarckism, Brooks consistently defended Darwin's theory of natural selection on logical grounds, continued to challenge the idea of the inheritance of acquired characteristics, and argued that natural selection best explained a wide range of adaptations. Finally, he critiqued Galton's statistical view of heredity and argued that Galton had resurrected an outmoded typological concept of species, one which Darwin and other naturalists had shown to be incorrect. Brooks's ideas resemble the "biological species concept" of the twentieth century, as developed by evolutionary biologist Ernst Mayr and others. The late-nineteenth century was not a period of total "eclipse" of Darwinism, as biologists and historians have hitherto seen it. Although the "Modern Synthesis" refers to the reconciliation of post-Mendelian genetics with evolution by natural selection, we might adjust our understanding of how the synthesis developed by seeing it as the culmination of a longer discussion that extends back to the late-nineteenth century.

  2. Spin currents, relativistic effects and the Darwin interaction in the theory of hole superconductivity

    International Nuclear Information System (INIS)

    Hirsch, J.E.


    The existence of macroscopic spin currents in the ground state of superconductors is predicted within the theory of hole superconductivity. Here it is shown that the electromagnetic Darwin interaction is attractive for spin currents and repulsive for charge currents. It is also shown that the mere existence of spin currents implies that some electrons are moving at relativistic speeds in macroscopic superconductors, which in turn implies that the Darwin interaction plays a fundamental role in stabilizing the superconducting state

  7. Darwinism in Context: An interdisciplinary, highly contextualized course on nature of science

    Directory of Open Access Journals (Sweden)

    Kostas Kampourakis


    Full Text Available In this article, we describe a course, titled Darwinism in Context, which focuses on the social, cultural and scientific influences on the development of Darwin's theory. This was an interdisciplinary, highly contextualized nature of science course that aimed to help students learn about a core nature of science aspect: that there are historical, cultural and social influences on the practice and directions of science. For this purpose, the course was based on a well-documented historical case study: the development of Darwin's theory. The course consisted of five classes that focused on: (a Victorian society, (b the views and beliefs of scholars that had an impact on Darwin's thinking (historical influences, (c aspects of Darwin's personal and social life that influenced the publication of his theory (social influences, (d the reception of Darwin's theory and the relationship between religion and science (cultural influences and (e the relationship between science and literature. In all cases, teaching included presentations of the historical events but was mostly based on the analysis and discussion of excerpts from the respective original writings. During the classes only a few examples were presented; students were motivated to study further the original writings and identify some key concepts and ideas after the classes. It is concluded that this kind of highly contextualized nature of science instruction can provide students with a more authentic view of science.

  8. "How nationality influences Opinion": Darwinism and palaeontology in France (1859-1914). (United States)

    Cohen, Claudine


    This paper discusses the "non-reception" of Darwin's works and concepts in French palaeontology and palaeoanthropology between 1859 and 1914. Indeed, this integration was difficult, biased and belated, for ideological, intellectual and epistemological reasons: Clémence Royer's biased 1862 translation of Darwin's Origin of Species pulled its ideas toward "social darwinism", making them less attractive to the natural sciences. - French nationalism and the authority of religion, which imposed Cuvier's thinking until late into the century - the dominance of Lamarckian and neo-Lamarckian transformism in France, both in biology and in paleontology, which proposed the notion of orthogenetic laws and environmental determinations, and refused darwinian evolutionary mechanisms - obstacles inherent to the application of Darwin's concepts to palaeontology, namely the impossibility to identify evolutionary mechanisms through the fossil record, which was stressed by Darwin himself and underlined in turn by 19th century French palaeontologists. However, as I argue, in the course of the examined period, French palaeontology grew from refusal to a better understanding and evaluation of Darwin's thinking. The quest for intermediary forms, the construction of branching evolutionary trees and the attempts to reconstruct human biological and cultural evolution were important efforts toward an integration of some aspects of Darwinian views and practices into French palaeontology and plaeoanthropology. The 1947 Paris conference which brought together American Neo-darwinists and French paleontologists made Darwinian concepts better understood and triggered a revival of French palaeontology from the 1960s.

  9. The Mastodon in the room: how Darwinian is neo-Darwinism? (United States)

    Brooks, Daniel R


    Failing to acknowledge substantial differences between Darwinism and neo-Darwinism impedes evolutionary biology. Darwin described evolution as the outcome of interactions between the nature of the organism and the nature of the conditions, each relatively autonomous but both historically and spatially intertwined. Furthermore, he postulated that the nature of the organism was more important than the nature of the conditions, leading to natural selection as an inevitable emergent product of biological systems. The neo-Darwinian tradition assumed a creative rather than selective view of natural selection, with the nature of the organism determined by the nature of the conditions, rendering the nature of the organism and temporal contingency unnecessary. Contemporary advances in biology, specifically the phylogenetics revolution and evo-devo, underscore the significance of history and the nature of the organism in biology. Darwinism explains more biology better, and better resolves apparent anomalies between living systems and more general natural laws, than does neo-Darwinism. The "extended" or "expanded" synthesis currently called for by neo-Darwinians is Darwinism. Copyright © 2010 Elsevier Ltd. All rights reserved.

    International Nuclear Information System (INIS)

    Zorski, Henryk; Bazanski, Stanislaw; Gutowski, Roman; Slawianowski, Jan; Wilmanski, Krysztof; Wozniak, Czeslaw


    In the last 3 decades the field of mechanics has seen spectacular progress due to the demand for applications in problems of cosmology, thermonuclear fusion, metallurgy, etc. This book provides a broad and thorough overview on the foundations of mechanics. It discusses theoretical mechanics and continuum mechanics, as well as phenomenological thermodynamics, quantum mechanics and relativistic mechanics. Each chapter presents the basic physical facts of interest without going into details and derivations and without using advanced mathematical formalism. The first part constitutes a classical exposition of Lagrange's and Hamiltonian's analytical mechanics on which most of the continuum theory is based. The section on continuum mechanics focuses mainly on the axiomatic foundations, with many pointers for further research in this area. Special attention is given to modern continuum thermodynamics, both for the foundations and applications. A section on quantum mechanics is also included, since the phenomenological description of various quantum phenomena is becoming of increasing importance. refs.; figs.; tabs

  11. As teorias de Lamarck e Darwin nos livros didáticos de Biologia no Brasil Lamarck's and Darwin's theories in text books of Biology in Brazil

    Full Text Available As teorias de Lamarck e Darwin são analisadas numa amostra de livros didáticos brasileiros de biologia, num período de sessenta anos. A de Darwin ocupa, nos livros didáticos, uma área maior do que a de Lamarck. Nestes é variável a extensão do conteúdo de Lamarck. Dentre os livros, destacam-se as edições do BSCS. Nestas, pela primeira vez, é apresentado o exemplo da figura do alongamento do pescoço da girafa, para ilustrar as diferenças de abordagem entre as teorias, e reproduzido desde então na maioria dos livros didáticos. Na teoria de Darwin, o principal conceito referenciado pelos autores é o da seleção natural, e, na de Lamarck, a herança dos caracteres adquiridos. As duas teorias são diferentemente apresentadas nos livros didáticos de biologia no Brasil. Darwin é apresentado como modelo de cientista e Lamarck como um teórico especulativo, tendo a sua teoria consideravelmente deformada, distante da formulação original.Theories formulated by Lamarck and Darwin are analyzed in a sample of Brazilian textbooks on biology published in a period of sixty years. Darwin's theory is covered more than Lamarck's theory. Among the analyzed books, an important mention must be addressed for BSCS editions, since the example of the elongation of the giraffes" necks for illustrating differences between both theories is presented in this series for the first time, and since then has been adopted by the majority of other textbooks on biology. The main concepts presented as representative of Darwin's and Lamarck's theories by all textbooks are natural selection and the inheritance of acquired characters, respectively. Not only theories but also the authors are differently presented in reviewed textbooks: while Darwin is presented as a model of scientist, Lamarck appears as a speculative theoretician, his theoretical propositions being remarkably deformed and changed from their original formulations.

  12. Gustave Flaubert, Charles Dickens, and Isaac Pulvermacher's "magic band". (United States)

    Waits, Robert K


    Around 1850, Isaac L. Pulvermacher (1815-1884) joined the ranks of so-called "galvanists" who had, for nearly a century, been touting the shocks and sparks of electricity as a miracle cure for all ills, including neurological complaints such as palsy and hemiplegia. The famed authors, Gustave Flaubert (1821-1880), in France, and Charles Dickens (1812-1870), in England, although contemporaries, apparently never met or corresponded. But during their lives, they both became aware of Pulvermacher and his patented Hydro-Electric Chains, claimed to impart vigor and cure nearly every complaint. Pulvermacher's chains made a cameo appearance in Madame Bovary (1857), Flaubert's controversial (and most successful) novel. Among Dickens's last letters (1870) was an order for I. L. Pulvermacher and Company's "magic band." Since the Victorian age, electrical and magnetic cures, for better or worse, continue to be products of both the medical profession and quackery. © 2013 Elsevier B.V. All rights reserved.

  13. [Charles Miller Fisher: the grandmaster of neurological observation]. (United States)

    Fukutake, Toshio


    Charles Miller Fisher is widely regarded as the father of modern stroke neurology. He discovered almost all pathomechanisms of cerebral infarction, including embolism from atrial fibrillation, carotid artery disease, and lacunar infarcts and their syndromes, by the most meticulous clinico-pathological observations. Moreover, his work provided the basis for treatments such as anticoagulation, antiplatelet therapy, and carotid endarterectomy. He also contributed greatly to several topics of General Neurology; for example, migraine, normal pressure hydrocephalus, and Miller Fisher syndrome. In his late years, he tried to expand the neurological field to the more complex disorders of human behavior, including hysteria, dementia, and ill-defined pain syndromes. He thus became known as the grandmaster of refined neurological observation. His lifelong detailed studies were crucially important in helping neurologists all over the world recognize disorders and syndromes that had not previously been understood.

  14. The question of good and narrative identity in Charles Taylor

    Directory of Open Access Journals (Sweden)

    Beatriz Zergers Prado


    Full Text Available Modern life poses unprecedented challenges in dealing with the task of defining a stable identity and achieving self-fulfillment. It is possible sustain that is a legacy of Modernity that the personis the main character of her own life and configure it by means of autonomous decisions. It is true thatshe must decide, although she has to do so from deep convictions if she does not want to be influencedby a culture that —in Charles Taylor’s perspective— has trivialized the ideal of authenticity and hasexalted a freedom that increases individualism. This essay is focused on the actions full of significance and the adherence to true goods that shape the identity and its narrative. The basics are in the anthropology and ethics of the philosopher just mentioned.

The author provides the readers with the knowledge and basic thinking they require to successfully manage risk and uncertainty to support decision making. This updated edition reflects recent developments on risk and uncertainty concepts, representations and treatment. New material in Foundations of Risk Analysis includes:An up to date presentation of how to understand, define and

    Rao, M M; Lukacs, E


    Foundations of Stochastic Analysis deals with the foundations of the theory of Kolmogorov and Bochner and its impact on the growth of stochastic analysis. Topics covered range from conditional expectations and probabilities to projective and direct limits, as well as martingales and likelihood ratios. Abstract martingales and their applications are also discussed. Comprised of five chapters, this volume begins with an overview of the basic Kolmogorov-Bochner theorem, followed by a discussion on conditional expectations and probabilities containing several characterizations of operators and mea

    Miller, H Ronald


    A thorough and highly accessible resource for analysts in a broad range of social sciences. Optimization: Foundations and Applications presents a series of approaches to the challenges faced by analysts who must find the best way to accomplish particular objectives, usually with the added complication of constraints on the available choices. Award-winning educator Ronald E. Miller provides detailed coverage of both classical, calculus-based approaches and newer, computer-based iterative methods. Dr. Miller lays a solid foundation for both linear and nonlinear models and quickly moves on to dis

    Wu, James


    Drawing on the authors' two decades of experience in applied modeling and data mining, Foundations of Predictive Analytics presents the fundamental background required for analyzing data and building models for many practical applications, such as consumer behavior modeling, risk and marketing analytics, and other areas. It also discusses a variety of practical topics that are frequently missing from similar texts. The book begins with the statistical and linear algebra/matrix foundation of modeling methods, from distributions to cumulant and copula functions to Cornish--Fisher expansion and o
