  4. Charles Darwin's mitochondria.

    Hayman, John

    2013-05-01

    Charles Darwin's long-term illness has been the subject of much speculation. His numerous symptoms have led to conclusions that his illness was essentially psychogenic in nature. These diagnoses have never been fully convincing, however, particularly in regard to the proposed underlying psychological background causes of the illness. Similarly, two proposed somatic causes of illness, Chagas disease and arsenic poisoning, lack credibility and appear inconsistent with the lifetime history of the illness. Other physical explanations are simply too incomplete to explain the range of symptoms. Here, a very different sort of explanation will be offered. We now know that mitochondrial mutations producing impaired mitochondrial function may result in a wide range of differing symptoms, including symptoms thought to be primarily psychological. Examination of Darwin's maternal family history supports the contention that his illness was mitochondrial in nature; his mother and one maternal uncle had strange illnesses and the youngest maternal sibling died of an infirmity with symptoms characteristic of mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS syndrome), a condition rooted in mitochondrial dysfunction. Darwin's own symptoms are described here and are in accord with the hypothesis that he had the mtDNA mutation commonly associated with the MELAS syndrome. PMID:23633139

    2003-01-01

    Several recent works in sociology examine the manufacture of public identities through the notion of celebrity. This paper explores the imagery of Charles Darwin as a nineteenth-century scientific celebrity by comparing the public character deliberately manufactured by Darwin and his friends with images constructed by the public as represented here by caricatures in humorous magazines of the era. It is argued that Darwin’s outward persona drew on a subtle tension between public and private. T...

  7. Charles Darwin's earthquake reports

    2010-05-01

    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

    Full Text Available 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, beetles and phylogenetics

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

    2009-11-01

    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

Than we shall present his four suppositions important for preservation and evolution of moral sense. After that we will consider the issue of relation between inherited and acquired moral properties and main characteristics which according to Darwin, make difference between social instinct in lower animals and moral sense in man. At the end some we shall present some arguments for thesis that in evolutionary scientific approach to ethics there is no room for unbridgeable gap between facts and values, 'ought' and 'is', and some arguments for thesis that from the point of view of the theory of evolution we can have descriptive ethics, but not any prescriptive or normative ethics except predictions that some moral beliefs and behaviors can be evolutionary successful.

  14. Evolutionary plant physiology: Charles Darwin's forgotten synthesis

    Science.gov (United States)

    Kutschera, Ulrich; Niklas, Karl J.

    2009-11-01

    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.

    2010-05-01

    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

    Full Text Available Over 175 years ago Charles Robert Darwin arrived in Argentina to find a bare and boundless plain, the brave centaur called "gaucho", Quaternary fossils everywhere, and a society strikingly strange and aggressive to the British eyes of the young traveller. Although the voyage aboard HMS Beagle was the indispensable way towards increasing his stature as a biologist, Lyell's work awakened an inquisitive geological mind which allowed him to wonder at the splendour of the Andes. Forty-two years after having concluded his voyage on the Beagle, the National Academy of Sciences of Argentina appointed him as an Honorary Member. This must be interpreted as an early gesture of recognition -in the context of those times- to the magnificence of his scientific work.Hace más de 175 años, Charles Robert Darwin llegaba a la Argentina para descubrir una llanura desprovista de límites y de árboles, el valeroso centauro que era el gaucho, fósiles cuaternarios por doquier y una sociedad sorprendentemente extraña y agresiva a los británicos ojos del joven viajero. Aunque el viaje a bordo del Beagle fue el camino indispensable para incrementar su estatura como biólogo, la obra de Lyell despertó una mente inquisitivamente geológica que le permitió maravillarse ante la magnificencia de los Andes. Cuarenta y dos años después de haber concluido su viaje en el Beagle, la Academia Nacional de Ciencias de Argentina lo designó Miembro Honorario, en lo que debe interpretarse como un temprano gesto de reconocimiento -en el contexto del momento- por la magnificencia de su obra científica.

  5. Charles Darwin and Evolution: Illustrating Human Aspects of Science

    Kampourakis, Kostas; McComas, William F.

    2010-06-01

    Recently, the nature of science (NOS) has become recognized as an important element within the K-12 science curriculum. Despite differences in the ultimate lists of recommended aspects, a consensus is emerging on what specific NOS elements should be the focus of science instruction and inform textbook writers and curriculum developers. In this article, we suggest a contextualized, explicit approach addressing one core NOS aspect: the human aspects of science that include the domains of creativity, social influences and subjectivity. To illustrate these ideas, we have focused on Charles Darwin, a scientist whose life, work and thought processes were particularly well recorded at the time and analyzed by scholars in the succeeding years. Historical facts are discussed and linked to core NOS ideas. Creativity is illustrated through the analogies between the struggle for existence in human societies and in nature, between artificial and natural selection, and between the division of labor in human societies and in nature. Social influences are represented by Darwin’s aversion of criticism of various kinds and by his response to the methodological requirements of the science of that time. Finally, subjectivity is discussed through Darwin’s development of a unique but incorrect source for the origin of variations within species.

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

    Full Text Available Article in German, Abstracts in English and German.While it is well known that Charles Darwin and Alexander von Humboldt appreciated each other's work, Humboldt's influence on Darwin has not yet been thoroughly examined. The following paper shows to what extent Darwin was inspired by Humboldt's publications while writing his Origin of Species.Darwin paid special attention to Humboldt's observations on plant migration and throughout his whole scientific career he used Humboldt's books as a major source of information. In fact, Darwin's last annotations in his copy of the Personal Narrative of travels to the Equinoctial Regions of the New continent during the Years 1799-1804 date back to the last weeks of his life.On the other hand, Darwin rejected many of Humboldt's scientific conclusions. The two authors differed in their assessment of Heinrich Bronn's biological research. Finally, Darwin was dissatisfied with Humboldtís last work Cosmos because it did not contain the information he expected. Darwinís collaboration with Humboldt's travel companion Christian Gottfried Ehrenberg proved to be similarly disappointing. Darwin sent 183 samples of infusoria to Berlin, but the results of Ehrenberg's analysis did not support Darwin's theory on evolution.

    During the celebrated voyage of HMS Beagle, Charles Darwin visited the Falkland Islands twice, in March 1833 and March 1834. He thought the islands bleak and inhospitable, but was much excited during his first visit to discover fossils at Port Louis. These he recognised as brachiopods (a type of shellfish) and crinoids (often described descriptively as ‘sea-lilies’ but actually animals related to sea urchins); an example of the kind of fossils that he saw is shown in Figure 1.

  15. Charles Darwin's beagle voyage, fossil vertebrate succession, and "the gradual birth & death of species".

    Science.gov (United States)

    Brinkman, Paul D

    2010-01-01

    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.

  18. Darwinian hydrology: can the methodology Charles Darwin pioneered help hydrologic science?

    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.

    Full Text Available TheRodados Patagónicos is one of the most intriguing lithostratigraphic unitsin the Late Cenozoic of Patagonia. Charles Darwin named these gravels as the "PatagonianShingle Formation", when he discovered them during his trip toPatagonia on board HMS Beagle in 1832. According to the prevailing paradigm ofthe time, he assigned these deposits to a giant transgression during the GreatUniversal Déluge epoch, considering that their formation was related to waveaction along the beach in ancient times. The name of Rodados Patagónicos,as they are generally known in the Argentine geological literature, is usuallyconfusing since it has been applied to a wide number of geological units ofmultiple origin and age. Many authors have discussed the nature and origin ofthese gravels, considering them to have been formed by piedmont, alluvial,colluvial, glaciofluvial, and/or marine processes. Today, it is accepted thatthe term Rodados Patagónicos includes gravel deposits of varied nature and age,perhaps with a prevalence of piedmont genesis in northern Patagonia andglaciofluvial dynamics in southern Patagonia and Tierra del Fuego.

  7. Charles Darwin's Origin of Species, directional selection, and the evolutionary sciences today

    2009-11-01

    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

  9. Explosive Volcanic Activity at Extreme Depths: Evidence from the Charles Darwin Volcanic Field, Cape Verdes

    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

    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.

    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.

    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. PMID:25455541

Esta fase es conocida como mínimo de Dalton, en referencia a la disminución relativa de la frecuencia de las manchas solares, lo cual redunda en una disminución de la radiación solar y como consecuencia, en menores temperaturas medias globales en ese período.

Desde el viaje de Darwin a la Patagonia, las condiciones climáticas y ambientales cambiaron sustancialmente, especialmente luego de 1850 AD y, finalmente, después de mediados de la década de 1970 AD. Algunas de las más importantes consecuencias del cambio climático global son el aumento de la temperatura media anual o la temperatura estacional, la elevación o disminución de las precipitaciones al nivel regional, el continuo ascenso global del nivel del mar y un incremento significativo de la frecuencia de eventos meteorológicos extremos.

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.

    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.

    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

  7. 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)

    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.

The great floral diversity and the outstanding number of reproductive strategies that promote cross-pollination in Orchidaceae fascinated Darwin who, in turn, used this plant group as a model to support his ideas. Darwin described for the first time and in a very accurate way, orchid reproductive strategies that clearly promote cross-pollination, such as protandry in terrestrial orchids and the production of unisexual flowers in Catasetum, among many other important

Esta fase es conocida como mínimo de Dalton, en referencia a la disminución relativa de la frecuencia de las manchas solares, lo cual redunda en una disminución de la radiación solar y como consecuencia, en menores temperaturas medias globales en ese período. Darwin fue perfectamente consciente de dichas condiciones climáticas, que se manifestaban fuertemente en Europa, en particular en los Alpes, y así lo transmite en sus escritos. Desde el viaje de Darwin a la Patagonia, las condiciones climáticas y ambientales cambiaron sustancialmente, especialmente luego de 1850 AD y, finalmente, después de mediados de la década de 1970 AD. Algunas de las más importantes consecuencias del cambio climático global son el aumento de la temperatura media anual o la temperatura estacional, la elevación o disminución de las precipitaciones al nivel regional, el continuo ascenso global del nivel del mar y un incremento significativo de la frecuencia de eventos meteorológicos extremos. El impacto de esos cambios ha sido observado en los glaciares de Patagonia y Tierra del Fuego, por lo menos desde 1978 AD, y particularmente en la última década del siglo XX. Los impactos más notables son la rápida recesión de las márgenes del hielo en los glaciares, el adelgazamiento de la cobertura glacial, la elevación de la línea de nieve regional y la reducción de las áreas andinas bajo condiciones de suelos permanentemente congelados (permafrost, como han demostrado estudios científicos recientes.

    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.

    Today, many would assume that Charles Darwin absolutely rejected any claim of intelligent design in nature. However, review of his initial writings reveals that Darwin accepted some aspects of this view. His conceptualization of design was founded on both the cosmological and the teleological ideas...... 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...

  5. Is neural Darwinism Darwinism?

    Science.gov (United States)

    van Belle, T

    1997-01-01

    Neural Darwinism is a theory of cognition developed by Gerald Edelman along with George Reeke and Olaf Sporns at Rockefeller University. As its name suggests, neural Darwinism is modeled after biological Darwinism, and its authors assert that the two processes are strongly analogous. both operate on variation in a population, amplifying the more adaptive individuals. However, from a computational perspective, neural Darwinism is quite different from other models of natural selection, such as genetic algorithms. The individuals of neural Darwinism do not replicate, thus robbing the process of the capacity to explore new solutions over time and ultimately reducing it to a random search. Because neural Darwinism does not have the computational power of a truly Darwinian process, it is misleading to label it as such. to illustrate this disparity in adaptive power, one of Edelman's early computer experiments, Darwin I, is revisited, and it is shown that adding replication greatly improves the adaptive power of the system.

The article examines both professional and popular commemorative...... 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...

    While musical genius must have neuro-biological basis it is defined and understood within prevailing cultural frameworks. In order to measure it historic and aesthetic traditions and assumptions need to be considered. Child prodigies and savants are discussed as well as traditional associations that suggest that depression and the melancholic personality have particular relevance in musical creativity and originality.

The reason, Frank argues, is that Darwin's understanding of competition describes economic reality far more accurately than Smith's. A...

    One of the classic examples of adaptive radiation under natural selection is the evolution of 15 closely related species of Darwin's finches (Passeriformes), whose primary diversity lies in the size and shape of their beaks. Since Charles Darwin and other members of the Beagle expedition collected these birds on the Galápagos Islands in 1835 and introduced them to science, they have been the subjects of intense research. Many biology textbooks use Darwin's finches to illustrate a variety of topics of evolutionary theory, such as speciation, natural selection and niche partitioning. Today, as this Theme Issue illustrates, Darwin's finches continue to be a very valuable source of biological discovery. Certain advantages of studying this group allow further breakthroughs in our understanding of changes in recent island biodiversity, mechanisms of speciation and hybridization, evolution of cognitive behaviours, principles of beak/jaw biomechanics as well as the underlying developmental genetic mechanisms in generating morphological diversity. Our objective was to bring together some of the key workers in the field of ecology and evolutionary biology who study Darwin's finches or whose studies were inspired by research on Darwin's finches. Insights provided by papers collected in this Theme Issue will be of interest to a wide audience. PMID:20194163

    2010-06-01

    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. PMID:20569987

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

    CERN Document Server

    Murdock, Jaimie; DeDeo, Simon

    2015-01-01

    Search in an environment with an uncertain distribution of resources involves a trade-off between local exploitation and distant exploration. This extends to the problem of information foraging, where a knowledge-seeker shifts between reading in depth and studying new domains. To study this, we examine the reading choices made by one of the most celebrated scientists of the modern era: Charles Darwin. Darwin built his theory of natural selection in part by synthesizing disparate parts of Victorian science. When we analyze his extensively self-documented reading we find shifts, on multiple timescales, between choosing to remain with familiar topics and seeking cognitive surprise in novel fields. On the longest timescales, these shifts correlate with major intellectual epochs of his career, as detected by Bayesian epoch estimation. When we compare Darwin's reading path with publication order of the same texts, we find Darwin more adventurous than the culture as a whole.

  17. Entomological reactions to Darwin's theory in the nineteenth century.

    Science.gov (United States)

    Kritsky, Gene

    2008-01-01

    Charles Darwin first became interested in entomology during his childhood, and this interest grew into a beetle-collecting obsession during his college days. Following the voyage of the Beagle, his focus on insects shifted from collecting specimens to searching for insect observations that supported his theory of natural selection as proposed in On the Origin of Species. Initially, Darwin believed that entomologists were opposed to his views. Using Darwin's correspondence, I show that his perception was based, in part, on three reviews, including one that he erroneously attributed to an entomological critic, and that not all entomologists were opposed to his ideas. Henry Walter Bates, discoverer of Batesian mimicry, voiced his support of Darwin in his papers and during meetings of the (now Royal) Entomological Society. In America, entomologist Benjamin D. Walsh wrote to Darwin in 1864, expressing his support and promising to counter any anti-Darwinian attack, and by 1868, Darwin was enjoying significant entomological support on both sides of the Atlantic. After his death in 1882, Darwin's supporters gained influence in Britain and the United States, completing entomology's shift to a Darwinian perspective. PMID:18067444

    This biography explores the life and career of the Italian physicist Enrico Fermi, which is also the story of thirty years that transformed physics and forever changed our understanding of matter and the universe: nuclear physics and elementary particle physics were born, nuclear fission was discovered, the Manhattan Project was developed, the atomic bombs were dropped, and the era of “big science” began. It would be impossible to capture the full essence of this revolutionary period without first understanding Fermi, without whom it would not have been possible. Enrico Fermi: The Obedient Genius attempts to shed light on all aspects of Fermi’s life - his work, motivation, influences, achievements, and personal thoughts - beginning with the publication of his first paper in 1921 through his death in 1954. During this time, Fermi demonstrated that he was indeed following in the footsteps of Galileo, excelling in his work both theoretically and experimentally by deepening our understanding of the Pauli e...

    Science.gov (United States)

    Noguera-Solano, Ricardo; Ruiz-Gutiérrez, Rosaura

    2009-01-01

    An important historical relation that has hardly been addressed is the influence of Prosper Lucas's Treatise on Natural Inheritance on the development of Charles Darwin's concepts related to inheritance. In this article we trace this historical connection. Darwin read Lucas's Treatise in 1856. His reading coincided with many changes concerning his prior ideas on the transmission and expression of characters. We consider that this reading led him to propose a group of principles regarding prepotency, hereditary diseases, morbid tendencies and atavism; following Lucas, he called these principles: laws of inheritance.

    This article deals with military genius from an historical and a classical theory perspective. The author modifies an approach developed by Carl von Clausewitz that makes use of theory as a framework for the study of history. Clausewitz used theory to study campaigns of Napoleon. This article uses Clausewitz's theory of military genius to study some of the great captains of the American Civil War and World War II. Using seven qualities of military genius that Clausewitz lists in his ON WAR, a study was made to ascertain commonalities of behavior displayed by great battlefield generals. Historical examples are given which reflect the qualities of military genius. The basic hypothesis of the article is that successful generals command their armies with their total being and not just one predominate aspect of their person. The underlying theme is that body, emotions, mind, and spirit must work in a relatively balanced manner which results in military genius being displayed. Historical example urges each senior officer to continually train and discipline his being in preparation for his possible future destiny.

  5. Marcel Proust: genius and insomnia.

    Marcel Proust is considered one the greatest novelists of all times. His life was characterised by a long list of diseases. We analyse an important illness suffered by Proust: insomnia. It began in childhood and continued throughout his life, worsening progressively, and leading to a complete reversal of the sleep-wake cycle in the last years of the novelist's life. Several factors may be involved in the pathogenesis of Proust's insomnia. The beginning of insomnia since childhood, its characteristics, and the lack of precipitating factors suggest a form of idiopathic insomnia. Psychological traits of his personality (severe anxiety and depression) may have played a central role in the onset of insomnia. Further factors such as asthma and intake of stimulating substances may have had an important role in the maintenance and worsening of his insomnia. This sleep disorder affected both the lifestyle and literary genius of Marcel Proust. Insomnia is the prominent figure in the first novel ("Swann's way") of Proust's masterpieces entitled "In search of lost time," in which the novelist begins his journey through involuntary memory starting from his insomnia.

  6. Human Dynamics: The Correspondence Patterns of Darwin and Einstein

    Oliveira, J G

    2005-01-01

    While living in different historical era, Charles Darwin (1809-1882) and Albert Einstein (1879-1955) were both prolific correspondents: Darwin sent (received) at least 7,591 (6,530) letters during his lifetime while Einstein sent (received) over 14,500 (16,200). Before email scientists were part of an extensive university of letters, the main venue for exchanging new ideas and results. But were the communication patterns of the pre-email times any different from the current era of instant access? Here we show that while the means have changed, the communication dynamics has not: Darwin's and Einstein's pattern of correspondence and today's electronic exchanges follow the same scaling laws. Their communication belongs, however, to a different universality class from email communication, providing evidence for a new class of phenomena capturing human dynamics.

    Charles Darwin's On the Origin of Species is at once familiar and unfamiliar. Everyone knows that the Origin introduced the world to the idea of evolution by natural selection, but few of us have actually read it. We suggest that it is worth taking the time not only to read what Darwin had to say, but also to use the Origin to teach both biology and writing. It provides scientific lessons in areas beyond evolutionary biology, such as ecology and biogeography. In addition, it provides valuable rhetorical lessons-how to construct an argument, write persuasively, make use of evidence, know your audience, and anticipate counterarguments. We have been using the Origin in various classes for several years, introducing new generations to Darwin, in his own words. PMID:26315858

  13. Engaging with Lyell: Alfred Russel Wallace's Sarawak Law and Ternate papers as reactions to Charles Lyell's Principles of Geology.

    Costa, J T

    2013-12-01

    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. PMID:24014172

    2010-10-01

    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.

    Science.gov (United States)

    Charlesworth, Brian; Charlesworth, Deborah

    2009-11-01

    Darwin's theory of natural selection lacked an adequate account of inheritance, making it logically incomplete. We review the interaction between evolution and genetics, showing how, unlike Mendel, Darwin's lack of a model of the mechanism of inheritance left him unable to interpret his own data that showed Mendelian ratios, even though he shared with Mendel a more mathematical and probabilistic outlook than most biologists of his time. Darwin's own "pangenesis" model provided a mechanism for generating ample variability on which selection could act. It involved, however, the inheritance of characters acquired during an organism's life, which Darwin himself knew could not explain some evolutionary situations. Once the particulate basis of genetics was understood, it was seen to allow variation to be passed intact to new generations, and evolution could then be understood as a process of changes in the frequencies of stable variants. Evolutionary genetics subsequently developed as a central part of biology. Darwinian principles now play a greater role in biology than ever before, which we illustrate with some examples of studies of natural selection that use DNA sequence data and with some recent advances in answering questions first asked by Darwin.

    Darwin's contributions to evolutionary biology are well known, but his contributions to genetics are much less known. His main contribution was the collection of a tremendous amount of genetic data, and an attempt to provide a theoretical framework for its interpretation. Darwin clearly described almost all genetic phenomena of fundamental importance, such as prepotency (Mendelian inheritance), bud variation (mutation), heterosis, reversion (atavism), graft hybridization (Michurinian inheritance), sex-limited inheritance, the direct action of the male element on the female (xenia and telegony), the effect of use and disuse, the inheritance of acquired characters (Lamarckian inheritance), and many other observations pertaining to variation, heredity and development. To explain all these observations, Darwin formulated a developmental theory of heredity - Pangenesis - which not only greatly influenced many subsequent theories, but also is supported by recent evidence.

    Full Text Available A partir del siglo XIX, se tomaron dos caminos distintos en la historia de la ciencia económica. Casi simultáneamente, la revolución darwiniana y la revolución marginalista tuvieron lugar pero sus intenciones ulteriores no pudieron ser más opuestas. La teoría de Darwin de la evolución de las especies por medio de la selección natural, se convirtió en un desafío a la visión del mundo dominante: la newtoniana (Witt, 1999. Este desafío al ideal newtoniano, fue influido, paradójicamente, por estímulos intelectuales proveniente de pensadores fuera de la biología. Estas influencias emanaron de la filosofía liberal del -dejar pasar, dejar hacer- de los siglos XVIII y de principios del siglo XIX. De los diarios de Darwin se destaca la correspondencia con Herbert Spencer, en donde se denota una clara influencia del trabajo de economistas-filósofos como Adam Smith, de la llamada escuela de Edimburgo, y Robert Malthus. Lo paradójico de esta situación es que ahora es Darwin quien, de vuelta, influye sobre los economistas modernos. La revolución darwiniana en la economía moderna consiste en mostrar al capitalismo como un proceso evolucionario explicado por procesos del cambio de patrones en las relaciones entre entidades. Pero gran parte de este estudio de influencia darwiniana no tiene que ver en sí con el estudio de la biología. Está relacionado con los principios y conceptos que definen el mecanismo evolucionario que es fundamento del desarrollo de la teoría evolucionista moderna.

  7. An Amphibious Being: How Maritime Surveying Reshaped Darwin's Approach to Natural History.

    Science.gov (United States)

    Sponsel, Alistair

    2016-06-01

    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.

    Since his visit to Tierra del Fuego in the 1830s, Darwin had been fascinated by the "savages" that succeeded in surviving on such a "broken beach", and because they were certainly similar in behaviour to our ancestors. However, he was also fascinated by baboons' behaviour, according to Brehm's accounts: hamadryas baboons showed a strong altruism to the point of risking their own lives in order to save their infants from attack by dogs. In 1871, he mentions he would rather have descended from brave baboons than from "savages", considered egoistic. We study the two sources of these ideas and try to show how Darwin's comparative reflections on apes and "savages" made him the first evolutionist anthropologist. PMID:20338533

  13. Darwin's artificial selection analogy and the generic character of "phyletic" evolution.

    Science.gov (United States)

    Alter, Stephen G

    2007-01-01

    This paper examines the way Charles Darwin applied his domestic breeding analogy to the practical workings of species evolution: that application, it is argued, centered on Darwin's distinction between methodical and unconscious selection. Methodical selection, which entailed pairing particular individuals for mating purposes, represented conditions of strict geographic isolation, obviously useful for species multiplication (speciation). By contrast, unconscious selection represented an open landmass with a large breeding population. Yet Darwin held that this latter scenario, which often would include multiple ecological subdistricts and thus partial isolation, was better suited for speciation than were isolated conditions. At the same time, many passages in Darwin's writings that apparently portrayedphyletic evolution exclusively (these including references to unconscious selection), actually applied to speciation as well, for phyletic change in a single district could constitute a local manifestation of a larger common-descent pattern. This generic use of "phyletic" change was reflected in Darwin's deployment of the unconscious selection analogy in his published writings as well as in his dispute with Moritz Wagner over the necessity of geographic isolation for speciation. We can thus understand Darwin's otherwise puzzling declaration in The Origin of Species that unconscious selection was 'more important' than the methodical approach. PMID:18411837

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

    Directory of Open Access Journals (Sweden)

    Sharad Master

    2012-09-01

    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.

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.

    In late September 2014 development of the Lake Charles Clean Energy (LCCE) Plant was abandoned resulting in termination of Lake Charles Carbon Capture and Sequestration (CCS) Project which was a subset the LCCE Plant. As a result, the project was only funded through Phase 2A (Design) and did not enter Phase 2B (Construction) or Phase 2C (Operations). This report was prepared relying on information prepared and provided by engineering companies which were engaged by Leucadia Energy, LLC to prepare or review Front End Engineering and Design (FEED) for the Lake Charles Clean Energy Project, which includes the Carbon Capture and Sequestration (CCS) Project in Lake Charles, Louisiana. The Lake Charles Carbon Capture and Sequestration (CCS) Project was to be a large-scale industrial CCS project intended to demonstrate advanced technologies that capture and sequester carbon dioxide (CO2) emissions from industrial sources into underground formations. The Scope of work was divided into two discrete sections; 1) Capture and Compression prepared by the Recipient Leucadia Energy, LLC, and 2) Transport and Sequestration prepared by sub-Recipient Denbury Onshore, LLC. Capture and Compression-The Lake Charles CCS Project Final Technical Report describes the systems and equipment that would be necessary to capture CO2 generated in a large industrial gasification process and sequester the CO2 into underground formations. The purpose of each system is defined along with a description of its equipment and operation. Criteria for selection of major equipment are provided and ancillary utilities necessary for safe and reliable operation in compliance with environmental regulations are described. Construction considerations are described including a general arrangement of the CCS process units within the overall gasification project.

    Bento, Ricardo Ferreira

    2009-09-01

    Full Text Available Introduction: Ludwig van Beethoven, one of the greatest composers in History, was tormented for his whole life by a progressive deafness without definitive diagnosis. Many authors published studies about the etiologic possibilities of the deafness of the music genius with different explanations about his auditory loss. In this work, the author discusses the implications of Beethoven's progressive deafness to the creation of his word, as well as etiologic assumptions of his disease. Would Beethoven have had the same ingeniousness he showed in his symphonies if he did not have hypacusis and tinnitus? What is the influence of his deafness on his work and life? Could he have had a more precise diagnosis and specially a treatment nowadays? Would we have the brilliant composer if he had deafness today? We surely could not have!

  4. Darwin at Puente del Inca: observations on theformation of the Inca's bridge and mountain building

    2009-04-01

    Full Text Available Theanalyses of the observations of Charles Darwin at Puente del Inca, during hissecond journey across the High Andes drew attention on two different aspects ofthe geological characteristics of this classic area. Most of his descriptionson the characteristics and the origin of the natural bridge were not published,mainly due to his poor impression of Puente del Inca. However, the applicationof the uniformitarian principles shows that it was formed as an ice bridgeassociated with snow and debris avalanches later on cemented by the mineralsprecipitated by the adjacent hot-water springs. Darwin's observations on the complexstructural section at Puente del Inca, together with his findings of shallowwater marine fossil mollusks in the thick stratigraphic column of the areainterfingered with volcanic rocks, led him to speculate on several geologicalprocesses. Based on his geological observations, Darwin argued on the mountain uplift, thesubsidence of the marine bottom, the episodic lateral growth of the cordillera,and their association with earthquakes and volcanic activity, which was animportant advance in the uniformitarian hypothesis of mountain uplift proposedby Charles Lyell. Darwin was able to recognize the episodic nature of mountain uplift, and basedon these premises he concluded that the Andes were still undergoing uplift. Takenas a whole, his ideas anticipated in many years some of the premises of thegeosynclinal theory, and current hypothesis on foreland migration of the foldand thrust belts.

    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

    A partir del siglo xix, se tomaron dos caminos distintos en la historia de la ciencia económica. Casi simultáneamente, la revolución darwiniana y la revolución marginalista tuvieron lugar pero sus intenciones ulteriores no pudieron ser más opuestas. Las grandes teorías Darwin acerca de la evolución de la vida en la tierra y la evolución de las especies por medio de la selección natural, se convirtieron en no menos que un desafío a la visión del mundo dominante: la newtoniana (Witt 1999. Este desafío al ideal newtoniano, fue influido, paradójicamente, por estímulos intelectuales de pensadores fuera de la biología. Estas influencias emanaron de la filosofía social del "dejar pasar, dejar hacer" liberal de los siglos xviii y de principios del siglo xix. De los diarios de Darwin se destaca la correspondencia con Herbert Spencer, en donde se denota una clara influencia del trabajo de economistas-filósofos como Adam Smith, de la llamada Escuela de Edimburgo, y Robert Malthus. Lo paradójico de esta situación es que ahora es Darwin quien, de vuelta, influye sobre los economistas modernos. La revolución darwiniana en la economía moderna consiste en mostrar al capitalismo como un proceso evolucionario explicado por procesos del cambio de patrones en las relaciones entre entidades. Pero gran parte de este estudio de influencia darwiniana no tiene que ver en sí  con el estudio de la biología. Está relacionado con los principios y conceptos que definen el mecanismo evolucionario que es fundamento del desarrollo de la teoría evolucionista moderna. Desde el estudio del sistema natural,y sus disciplinas ¿qué podemos aprender en el campo de lo social en los temas de adaptabilidad, ante la adversidad y bio- y sociodiversidad?

    Science.gov (United States)

    Alter, Stephen G

    2007-09-01

    In his book The descent of man (1871), Charles Darwin paid tribute to a trio of writers (Hensleigh Wedgwood, F. W. Farrar, and August Schleicher) who offered naturalistic explanations of the origin of language. Darwin's concurrence with these figures was limited, however, because each of them denied some aspect of his thesis that the evolution of language had been coeval with and essential to the emergence of humanity's characteristic mental traits. Darwin first sketched out this thesis in his theoretical notebooks of the 1830s and then clarified his position in Descent, where he argued that mind-language coevolution had occurred prior to the rise of distinct racial groups. He thus opposed the view of August Schleicher and Ernst Haeckel, who (along with Alfred Russel Wallace) taught that speech had originated subsequent to the geographical and racial dispersion of humanity's ancestors. As Darwin argued in Descent, this quasi-polygenetic version of coevolution was unable to explain primeval man's initial dominance over rival ape-like populations. Drawing inspiration from British anthropologists, Darwin made the early development of language, hence mental monogenesis, central to his account of human evolution. PMID:17893066

  15. Darwin, artificial selection, and poverty.

    Science.gov (United States)

    Sanchez, Luis

    2010-03-01

    This paper argues that the processes of evolutionary selection are becoming increasingly artificial, a trend that goes against the belief in a purely natural selection process claimed by Darwin's natural selection theory. Artificial selection is mentioned by Darwin, but it was ignored by Social Darwinists, and it is all but absent in neo-Darwinian thinking. This omission results in an underestimation of probable impacts of artificial selection upon assumed evolutionary processes, and has implications for the ideological uses of Darwin's language, particularly in relation to poverty and other social inequalities. The influence of artificial selection on genotypic and phenotypic adaptations arguably represents a substantial shift in the presumed path of evolution, a shift laden with both biological and political implications.

  16. Separated at birth: the interlinked origins of Darwin's unconscious selection concept and the application of sexual selection to race.

    Science.gov (United States)

    Alter, Stephen G

    2007-01-01

    This essay traces the interlinked origins of two concepts found in Charles Darwin's writings: "unconscious selection," and sexual selection as applied to humanity's anatomical race distinctions. Unconscious selection constituted a significant elaboration of Darwin's artificial selection analogy. As originally conceived in his theoretical notebooks, that analogy had focused exclusively on what Darwin later would call "methodical selection," the calculated production of desired changes in domestic breeds. By contrast, unconscious selection produced its results unintentionally and at a much slower pace. Inspiration for this concept likely came from Darwin's early reading of works on both animal breeding and physical ethnology. Texts in these fields described the slow and unplanned divergence of anatomical types, whether animal or human, under the guidance of contrasting ideals of physical perfection. These readings, it is argued, also led Darwin to his theory of sexual selection as applied to race, a theme he discussed mainly in his book The Descent of Man (1871). There Darwin described how the racial version of sexual selection operated on the same principle as unconscious selection. He thereby effectively reunited these kindred concepts. PMID:18175603

    Schizophrenia has many negative impacts on the wellbeing of individuals (sufferers). I will critically analyse Nash's experience with his illness of schizophrenia and his concept of wellness based on themes, his journey with schizophrenia and the support of this wife and friends. Ron Howard directed the movie, A Beautiful Mind based on Nash's biography about his mathematical genius and his struggle with schizophrenia. Nash only had one sister, Martha Nash who was born on November 16th, 1930. In terms of his mental health and wellness, Nash began to show signs of schizophrenia in 1958, on the threshold of his career. After 1970, by his choice, he never took antipsychotic medication again. In 1978, Nash was awarded the John von Neumann Theory Prize for his discovery of non-cooperative equilibria, now called Nash equilibria. As a result of Nash's illness, he adopted unhealthy practices that did not help him cope with schizophrenia. Recovery from mental illness has emphasised the importance of hope for the people experiencing mental illness. Nash's self-determinations enabled him to overcome the stigmatisation suffering due to schizophrenia. Nash experienced the five stages of coping with mental illness. The support of Nash's wife Alicia and the few close friends he had were paramount to his recovery and living with schizophrenia. Alicia had used cognitive coping strategies with her caring for Nash by having positive thinking in attempting to accept Nash's illness rather than denying that it existed and to understand the life experiences of a person with schizophrenia. Howard (2001) stated that it's about a 25% chance, that survivors of schizophrenia can regain clarity as Nash did within a certain time period. PMID:20443526

  19. Tracing the origin of a scientific legend by Reference Publication Year Spectroscopy (RPYS): the legend of the Darwin finches

    CERN Document Server

    Marx, Werner

    2013-01-01

    In a previews paper we introduced the quantitative method named Reference Publication Year Spectroscopy (RPYS). With this method one can determine the historical roots of research fields and quantify their impact on current research. RPYS is based on the analysis of the frequency with which references are cited in the publications of a specific research field in terms of the publication years of these cited references. In this study, we illustrate that RPYS can also be used to reveal the origin of scientific legends. We selected Darwin finches as an example for illustration. Charles Darwin, the originator of evolutionary theory, was given credit for finches he did not see and for observations and insights about the finches he never made. We have shown that a book published in 1947 is the most-highly cited early reference cited within the relevant literature. This book had already been revealed as the origin of the term Darwin finches by Sulloway through careful historical analysis.

    2010-01-01

    The Darwinian nature of Wojciech Zurek's theory of Quantum Darwinism is evaluated against the criteria of a Darwinian process as understood within Universal Darwinism. The characteristics of a Darwinian process are developed including the consequences of accumulated adaptations resulting in adaptive systems operating in accordance with Friston's free energy principle and employing environmental simulations. Quantum theory, as developed in Zurek's research program and encapsulated by his theory of Quantum Darwinism is discussed from the view that Zurek's derivation of the measurement axioms implies that the evolution of a quantum system entangled with environmental entities is determined solely by the nature of the entangled system. There need be no further logical foundation. Quantum Darwinism is found to conform to the Darwinian paradigm in unexpected detail and is thus may be considered a theory within the framework of Universal Darwinism. With the inclusion of Quantum Darwinism within Universal Darwinism a...

Epilepsy affects approximately 3 percent of the general population and is a complex disease. At least 11 genes have now been described for human epilepsy and over 50 more genes have been identified in animal models of epilepsy. The complex gene to gene interactions and gene-environment interactions may account for epilepsy susceptibility and antiepileptic drug response.

    Full Text Available Scarcely 23 km from Uspallata, along the track of the old national highway 7, lies the district of Agua de la Zorra, in Mendoza province in western Argentina. Charles Darwin visited the area during his South American journeys in the 19th century and discovered a geological sequence that contained a paleoflora never described before. The flora includes an important number of species, particularly what is considered a small conifer forest with many silicified trunks still in life position. Darwin described and interpreted the sequence as sedimentary; his records show a very detailed level of observation. He also wondered about the processes that would cause the burial of the paleoflora, which he considered had happened in a marine sedimentary environment. In the modern geological framework and after a detailed study of the rocks containing the trunks, it is now interpreted that the conifer forest was buried by pyroclastic flows. Darwin accurately described the fine volcanic materials as an essential part of the deposit, but the key of the enigma about the origin of the deposits and the burial of the forest is the identification of the pyroclastic flow features; these were unknown process at the time of Darwin´s observations and interpretation.

    2009-03-30

    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.

    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. PMID:25439138

Sostengo también que de este proyecto se derivan dos enseñanzas importantes, una para la filosofía moral y otra para la concepción de la selección natural. La primera es que los dilemas sociales están en el corazón de la moral humana; la segunda es que la cooperación está en el núcleo de la selección natural. Ilustro el segundo punto con investigaciones recientes sobre la evolución de los organismos multicelulares.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 multicellular organisms.

    Charles Darwin’s long-term illness has been the subject of much speculation. His numerous symptoms have led to conclusions that his illness was essentially psychogenic in nature. These diagnoses have never been fully convincing, however, particularly in regard to the proposed underlying psychological background causes of the illness. Similarly, two proposed somatic causes of illness, Chagas disease and arsenic poisoning, lack credibility and appear inconsistent with the lifetime history of th...

  19. Darwin teleologist? Design in The orchids.

    Science.gov (United States)

    Hoquet, Thierry

    2010-02-01

    Focusing on "The Orchids," this article aims at disentangling the concepts of teleology, design and natural theology. It refers to several contemporary critics of Darwin (Kölliker, Argyll, Royer, Candolle, Delpino) to challenge Huxley's interpretation that Darwin's system was "a deathblow" to teleology. "The Orchids" seems rather to be a "flank-movement" (Gray): it departs from the Romantic theories of transmutation and the "imaginary examples" of the Origin; it focuses on empirical data and on teleological structures. Although Darwin refers to natural selection, his readers mock him for his fascination for delicate morphological contrivances and co-adaptations - a sign that he was inescapably lured to finality. Some even suggested that his system was a "theodicy". In the history of Darwinism, "The Orchids" reveals "another" quite unexpected and heterodox Darwin: freed from the hypothetical fancies of the Origin, and even suggesting a new kind of physico-theology.

    Full Text Available The Agua de la Zorra area (near Uspallata, Mendoza, Argentina is one of the best renowned fossil localities of the country because of its spectacular in situ fossil forest. This forest was discovered by Charles Darwin in 1835, who described this forest as monotypic and assigned it a Tertiary age. Nowadays, this fossil locality is known as the Darwin Forest. Over a century and a half later it was reinterpreted as a mixed Middle Triassic forest and a new fossil monotypic palaeocommunity of horsetails was discovered. This palaeovegetation is included in the Paramillo Formation (i.e., lower section the Potrerillos Formation of northwestern Cuyo Basin, Mendoza province (69°12' W and 32°30' S. The sediments were deposited in a sinuous fluvial system, in which channel-filling sand bodies were associated with mud-dominated floodplain deposits. The palaeoforest grew on an andisol soil that developed on volcaniclastic floodplain deposits. It had a density of 427 -759 trees per hectare, and was constituted by conifers and corystosperms distributed in two arboreal strata. The highest reached 20-26 m tall, and was dominated by corystosperms, but it also included the tallest conifers. The second stratum, mainly composed of conifers, ranged between 16-20 m tall. The forest has also emergent corystosperms, which reached 30 m tall. The understorey was composed of ferns. Growth ring anatomy suggests that conifers could have had an evergreen habit. Structure of vegetation, growth ring analyses and sedimentation suggest that the forest developed under dry, subtropical, and strongly seasonal conditions.

    Full Text Available Duringhis two years in South America Charles Darwin became fascinated not only withthe lush vegetation of Brazil, but also with the gigantic Pleistocene mammals that hefound in the drier areas of Uruguay, and in the pampas and Patagonian coast of Argentina. These findings includedvarious ground sloths and glyptodonts among xenarthrans, and hoofed herbivoreslike Toxodon and Macrauchenia, in addition to horses and smallrodents. He concluded that the general assumption that large animals requireluxuriant vegetation was false and that vitiated the reasoning of geologists onsome aspects of Earth's history. He also reflected on the evident changes thatoccurred in the continent, the extinct fauna of which suggested to him ananalogy to southern parts of Africa. He wondered about our ignorance of biological traits inextinct creatures and the reasons for their extinction. Thus, not only did Darwin inspire phylogeneticstudies on fossil mammal lineages, he also opened a gate to the research ontheir behaviour, physiology and extinction; i.e., their palaeobiology. Whereasthe first approach was largely developed in South America beginning about thesecond half of the 19th century due to the intellectual influence ofFlorentino Ameghino, palaeobiology became a much more recent line of work, inapparent relation to innovations in methodology and technology. Thiscontribution provides an overview of recent contributions on the palaeobiologyof Pleistocene fossil mammals of South America as attempts to provide answers for Darwin's questions.

  4. Darwin's artificial selection as an experiment.

    Science.gov (United States)

    Wilner, Eduardo

    2006-03-01

    Darwin used artificial selection (ASN) extensively and variedly in his theorizing. Darwin used ASN as an analogy to natural selection; he compared artificial to natural varieties, hereditary variation in nature to that in the breeding farm; and he also compared the overall effectiveness of the two processes. Most historians and philosophers of biology have argued that ASN worked as an analogical field in Darwin's theorizing. I will argue rather that this provides a limited and somewhat muddled view of Darwinian science. I say "limited" because I will show that Darwin also used ASN as a complex experimental field. And I say "muddled" because, if we concentrate on the analogical role exclusively, we conceive Darwinian science as rather disconnected from contemporary conceptions of "good science". I will argue that ASN should be conceived as a multifaceted experiment. As a traditional experiment, ASN established the efficacy of Darwin's preferred cause: natural selection. As a non-traditional experiment, ASN disclosed the nature of a crucial element in Darwin's evolutionary mechanics: the nature of hereditary variation. Finally, I will argue that the experiment conception should help us make sense of Darwin's comments regarding the "monstrous" nature of domestic breeds traditionally considered to be problematic.

  5. Deceived by orchids: sex, science, fiction and Darwin.

    Science.gov (United States)

    Endersby, Jim

    2016-06-01

    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

    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.

    The notions of 'the Darwinian revolution' and of 'the scientific Revolution' are no longer unproblematic; so this paper does not construe its task as relating these two items to each other. There can be big-picture and long-run history even when that task is declined. Such history has to be done pluralistically. Relating Darwin's science to Newton's science is one kind of historiographical challenge; relating Darwin's science to seventeenth-century finance capitalism is another kind. Relating Darwin's science to long-run traditions and transitions is a different kind of task from relating his science to the immediate short-run contexts. PMID:25457644

    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.

    Shapovalov, A V

    1997-01-01

    We present a Hamiltonian approach for the wellknown Eigen model of the Darwin selection dynamics. Hamiltonization is carried out by means of the embedding of the population variable space, describing behavior of the system, into the space of doubled dimension by introducing additional dynamic variables. Besides the study of the formalism, we try to interpret its basic elements (phase space, Hamiltonian, geometry of solutions) in terms of the theoretical biology. A geometric treatment is given for the considered system dynamics in terms of the geodesic flows in the Euclidean space where the population variables serve as curvilinear coordinates. The evolution of the distribution function is found for arbitrary distributed initial values of the population variables.

    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...

  18. Bayesian Methods and Universal Darwinism

    Science.gov (United States)

    Campbell, John

    2009-12-01

    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.

  20. Formalizing Darwinism and inclusive fitness theory.

    Science.gov (United States)

    Grafen, Alan

    2009-11-12

    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.

In fact, Darwin held that the key evidence for common ancestry comes from characters whose evolution is not ca...

    DARWIN is a web-based system for presenting the results of wind-tunnel testing and computational model analyses to aerospace designers. DARWIN captures the data, maintains the information, and manages derived knowledge (e.g. visualizations, etc.) of large quantities of aerospace data. In addition, it provides tools and an environment for distributed collaborative engineering. We are currently constructing the third version of the DARWIN software system. DARWN's development history has, in some sense, tracked the development of web applications. The 1995 DARWIN reflected the latest web technologies--CGI scripts, Java applets and a three-layer architecture--available at that time. The 1997 version of DARWIN expanded on this base, making extensive use of a plethora of web technologies, including Java/JavaScript and Dynamic HTML. While more powerful, this multiplicity has proven to be a maintenance and development headache. The year 2000 version of DARWIN will provide a more stable and uniform foundation environment, composed primarily of Java mechanisms. In this paper, we discuss this evolution, comparing the strengths and weaknesses of the various architectural approaches and describing the lessons learned about building complex web applications.

During that journey, he crossed a vast plain characterized by aeolian sediments, something unfamiliar to a European naturalist. However, Darwin's acute observation powers and precise descriptions are noteworthy. After more than 170 years since his visit, modern geological knowledge identifies several sectors in the Buenos Aires-Santa Fe region.

    2011-12-01

    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.

Insights are gained about the tendency to move from an exclusive, elite, narrow concept of creativity, measured by the creation of products and their abundance, towards a broader, democratic concept of everyday creativity of the most people. The conclusion is that the creative industries of the exceptional creativity of genius or talent and mysticism are gradually transformed to broader creativity as the governed system, emphasizing creativity links with internal elements of the system and with the social context.

  7. Flu pandemics: homeopathic prophylaxis and definition of the epidemic genius

    Directory of Open Access Journals (Sweden)

    2009-09-01

    Full Text Available Recent studies on viral genetics establish swine-H1N1 – responsible for the ongoing pandemics – as a remainder or continuation of the agent causing the flu epidemics of 1918. This study aimed at analyzing whether this common etiology also result in significant correlations of clinical manifestations. To do so, data were collected to compare the clinical evolution of cases in the 1918 and 2009 epidemics.  This historical revision was the ground for evaluating the response to treatment including homeopathy in the former epidemics. It is discussed the convenience of including homeopathic prophylaxis grounded on the diagnosis of the epidemic genius among public health actions.

  8. The Darwin package for fuel cycle applications

    International Nuclear Information System (INIS)

    The DARWIN package, developed by the CEA and its French partners provides the required parameters for fuel cycle applications: fuel inventory, decay heat, activity, sources, spectra.... This paper presents the DARWIN2.3 package (based on the European evaluation file JEFF-3.1.1) and its experimental validation data base for fuel inventory and decay heat calculations. A synthesis of the DARWIN2.3 validation for the Pressurized Water Reactor (PWR) Uranium Oxide (UOX) and Mixed Oxide (MOX) fuel inventory and decay heat calculation is shown. An overview of the tendencies is presented on a complete range of burn-up from 10 to 85 GWd/t (10 to 60 GWd/t for MOX fuel). The experimental validation of the DARWIN2.3 package for decay heat calculation is performed using specific experiments: elementary fission bursts measurements and calorimetric measurements at different cooling time. New developments are being processed to insert deterministic uncertainty propagation in the DARWIN2.3 fuel cycle reference package. (authors)

    Scholars have usually given Darwin's theory a neo-Darwinian interpretation. A more careful examination of the language of Darwin's notebooks and the language of the Origin of Species indicates that he reconstructed nature with a definite purpose: the final goal of man as a moral creature. In the aftermath of the Origin, Darwin, however, became more circumspect.

    Diamandopoulos, A; Goudas, P

    2005-12-01

    The views on the biological relationship between human and ape are polarized. One end is summarized by the axiom that "man is the third chimpanzee", a thesis put forward in an indirect way initially by Charles Darwin in the 19th century. The other is a very modern concept that although similar, the human and ape genomes are distinctly different. We have compared these two views on the subject with the stance of the ancient medical writer Galen. There is a striking resemblance between current and ancient opinion on three key issues. Firstly, on the fact that man and apes are similar but not identical. Secondly, on the influence of such debates on fields much wider than biology. And finally, on the comparative usefulness of apes as a substitute for human anatomy and physiology studies. PMID:17153282

    Waelbers, Katinka; Dorstewitz, Philipp

    2014-03-01

    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. Darwin on the Treatment of Animals: His Thoughts Then and His Influence Now

    Directory of Open Access Journals (Sweden)

    Dr. Donna Yarri

    2013-06-01

    Full Text Available Charles Darwin’s theory of evolution has seriously challenged traditional religious views on the origins of life, as well as on our human-animal similarities. Darwin is often referenced in literature on animal ethics with regard to his contention that the difference between humans and other animals is one of degree rather than of kind. This paper posits that Darwin’s writings and theory make more positive contributions to the contemporary debate on animal ethics than for which he has previously been given credit. This paper addresses important aspects of Darwin’s theory for understanding our relationship with other animals and the implications for their subsequent treatment. First, this paper considers themes in Darwin’s original writings regarding relationships among different species; second, enhancements to his theory in support of these themes; and third, recommendations for how these themes can and should inform our moral reasoning and successive treatment of other animals.

  19. Charles Brenner: a practitioner's theorist.

    Science.gov (United States)

    Friedman, Lawrence

    2011-08-01

    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. PMID:21832122

  1. Postglacial Fringing-Reef to Barrier-Reef conversion on Tahiti links Darwin's reef types

    2014-01-01

    In 1842 Charles Darwin claimed that vertical growth on a subsiding foundation caused fringing reefs to transform into barrier reefs then atolls. Yet historically no transition between reef types has been discovered and they are widely considered to develop independently from antecedent foundations during glacio-eustatic sea-level rise. Here we reconstruct reef development from cores recovered by IODP Expedition 310 to Tahiti, and show that a fringing reef retreated upslope during postglacial sea-level rise and transformed into a barrier reef when it encountered a Pleistocene reef-flat platform. The reef became stranded on the platform edge, creating a lagoon that isolated it from coastal sediment and facilitated a switch to a faster-growing coral assemblage dominated by acroporids. The switch increased the reef's accretion rate, allowing it to keep pace with rising sea level, and transform into a barrier reef. This retreat mechanism not only links Darwin's reef types, but explains the re-occupation of reefs during Pleistocene glacio-eustacy. PMID:24845540

  2. On the formations of the Pampas inthe footsteps of Darwin: south of the Salado

    Directory of Open Access Journals (Sweden)

    Marcelo Zárate

    2009-04-01

    Full Text Available In1833 during his journey across the Buenos Aires Pampas, Charles Darwin madeobservations that reflected his thoughts on two major landscape units, Pampa interserrana and Pampa deprimida, later identified byother authors. Darwin grouped the Pampean sediments into a single unit, the PampeanFormation, based upon the lithological homogeneity and the large extensionof the deposits; the unit was thought to be of estuarine-marine origin andattributed to the Recent Epoch considering the paleontological content(vertebrates and mollusks. At present, the Pampean sedimentary succession,which accumulated approximately during the last 11-12 Ma, is interpreted as a pedosedimentarysequence due to the ubiquity of pedogenetic features throughout the deposits.Four main subcycles of sedimentation are identified related to reactivations ofthe Pampean landscape. At a regional scale, the outcrop distribution of Pampeansediments of different ages suggests the dominance of more stable conditionssince the late Miocene-Pliocene in a vast area of Pampa interserrana, documented by theformation of calcretes. However, sedimentation during the latePliocene-Pleistocene was active within the domain of the Salado tectonic basin andSierras de Tandil. The regional disparity shown by the Pampean stratigraphicrecord reveals the major morphostructural differences of its basement.

    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". PMID:22073768

  4. Limits of imagination: the 150th Anniversary of Mendel's Laws, and why Mendel failed to see the importance of his discovery for Darwin's theory of evolution.

    Science.gov (United States)

    Singh, Rama S

    2015-09-01

    Mendel is credited for discovering Laws of Heredity, but his work has come under criticism on three grounds: for possible falsification of data to fit his expectations, for getting undue credit for the laws of heredity without having ideas of segregation and independent assortment, and for being interested in the development of hybrids rather than in the laws of heredity. I present a brief review of these criticisms and conclude that Mendel deserved to be called the father of genetics even if he may not, and most likely did not, have clear ideas of segregation and particulate determiners as we know them now. I argue that neither Mendel understood the evolutionary significance of his findings for the problem of genetic variation, nor would Darwin have understood their significance had he read Mendel's paper. I argue that the limits to imagination, in both cases, came from their mental framework being shaped by existing paradigms-blending inheritance in the case of Darwin, hybrid development in the case of Mendel. Like Einstein, Darwin's natural selection was deterministic; like Niels Bohr, Mendel's Laws were probabilistic-based on random segregation of trait-determining "factors". Unlike Einstein who understood quantum mechanics, Darwin would have been at a loss with Mendel's paper with no guide to turn to. Geniuses in their imaginations are like heat-seeking missiles locked-in with their targets of deep interests and they generally see things in one dimension only. Imagination has limits; unaided imagination is like a bird without wings--it goes nowhere. PMID:26372894

  5. Combating plant diseases--the Darwin connection.

    Science.gov (United States)

    Hollomon, Derek W; Brent, Keith J

    2009-11-01

    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.

    2005-06-01

    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.

    Scientist. Innovator. Rebel. For decades, Freeman Dyson has been regarded as one of the world’s most important thinkers. The Atlantic wrote, “In the range of his genius, Freeman Dyson is heir to Einstein – a visionary who has reshaped thinking in fields from math to astrophysics to medicine, and who has conceived nuclear-propelled spaceships designed to transport human colonists to distance planets.” Salon.com says that, “what sets Dyson apart among an elite group of scientists is the conscience and compassion he brings to his work.” Now, in this first complete biography of Dyson, author Phillip F. Schewe examines the life of a man whose accomplishments have shaped our world in many ways. From quantum physics to national defense, from space to biotechnology, Dyson’s work has cemented his position as a man whose influence goes far beyond the field of theoretical physics.

    2009-07-01

    Full Text Available A perspective on (neo-Darwinism first of all has to account for those assumptions derived from the humanities, causing neo-Darwinism not to be a purely special scientific or natural scientific theory. A discussion of the many-sidedness of living entities highlights the difficulties surrounding a definition of biology. Attention is briefly given to the physicalism of Darwin’s 1859 work before the quest for origins is discussed. These considerations pave the way for an assessment of striking shortcomings in the thought of Darwin and his followers. In particular, modern nominalism is identified as an important source for neo-Darwinism, especially manifest in the idea that organisms are not types and do not have types (Simpson. Darwin’s idea of incremental (continuous change both in respect of the genesis of a complex organ (or the origination of the first living entity and of successive fossil forms contradict the current state of affairs – and the same applies to his own radical idea that “injurious” variations will be eliminated immediately by natural selection, for it cannot be reconciled to the role of mutations in neo-Darwinian theory. In addition neo-Darwinian paleontologists pointed out that evolution requires intermediate forms and paleontology does not provide them (Kitts and explicitly confessed that they have paid lip-service to the idea of change while they knew all the time that it was not true (Eldredge: the dominant theme of the paleontological record is stasis, constancy – a type appears and remains constant for millions of years before it disappears (Gould. The supposition of incremental continuity received a further blow from the “Cambrian explosion”, the “nasty fact” that most “major animal groups appeared simultaneously” about 530 million years ago. A few aspects of the uniqueness of humankind are treated as well as the confused picture found in an attempt to synthesise neo-Darwinism and Christianity. In

    The death of King Charles II, the Bewitched, ended two centuries of sovereignity of the Habsburg dynasty in Spain. Since his birth in 1661, he presented a peculiar set of physical, psychiatric and behavioral signs, such as respiratory and diarrheal diseases, recurrent seizures and deep developmental delay. It was not until his adulthood when his infertility became evident, being incapable of conceiving a heir, even though he married twice. Such a constellation of ominous signs motivated a curious investigation, which concluded that the king was hexed at the age of 14 years in order to take away his throne, his health and his capacity to procreate. Based on contemporary medical knowledge, it is possible that Charles IIhad a rare autosomal recessive inherited genopathy asa consequence of the frequent inbreeding among his ancestors. On the other hand, its is also possible that Charles II presented Klinefelter Syndrome, the most frequent sex chromosome disorder in humans and the most common cause of hypogonadism and infertility in males. The hypothesis that Charles II was bewitched reflects a deep belief in supernatural phenomena among the Castilian society at the beginning of the 18th century, an idea transmitted across generations, currently present in many societies worldwide.

    For those accustomed to thinking that the modern cultural dimension arose under the banner of a clash between the so-called "two cultures," the figure of Darwin the "humanist" could reserve numerous surprises. It was above all the well-known paleontologist S.J. Gould who pointed them out. He went so far as to track down, in the Italian cultural roots from Saint Francis to Galileo, an element of continuity between his own Darwinism and our literary tradition that passes through the writing of the masterpieces of the nineteenth-century natural sciences. On the basis of a similar, and also audacious, rereading of the cultural history, the essay proposes to indicate some possible developments of the new dialogue undertaken, beginning with the insertion of the scientist Darwin in the European horizon of the Republic of Letters. There are then indicated some historical-cultural categories that would merit reconsideration: the new figure of intellectual of the twenty-first century, the idea of a science immersed in the historical contingency and in the concrete pleasure of the subject that knows, the role of "sweetness" and of "wonder" also in the most rigorous study, and lastly the need of an in-depth knowledge of the Darwinian writing, not as a curiosity for the educational trend of the era of positivism, but as an indispensable epistemological requisite for a correct understanding of its science.

    Describing Service-Oriented Architecture (SOA) is critical in the development of Web-based system. In this paper, an approach for describing SOA by extended Darwin is proposed. The requirements for describing SOA, which are different from that of ordinary architecture, are highlighted firstly, and then a solution for extending Darwin is presented.

    Full Text Available Duringhis two years in South America Charles Darwin became fascinated not only withthe lush vegetation of Brazil, but also with the gigantic Pleistocene mammals that hefound in the drier areas of Uruguay, and in the pampas and Patagonian coast of Argentina. These findings includedvarious ground sloths and glyptodonts among xenarthrans, and hoofed herbivoreslike Toxodon and Macrauchenia, in addition to horses and smallrodents. He concluded that the general assumption that large animals requireluxuriant vegetation was false and that vitiated the reasoning of geologists onsome aspects of Earth's history. He also reflected on the evident changes thatoccurred in the continent, the extinct fauna of which suggested to him ananalogy to southern parts of Africa. He wondered about our ignorance of biological traits inextinct creatures and the reasons for their extinction. Thus, not only did Darwin inspire phylogeneticstudies on fossil mammal lineages, he also opened a gate to the research ontheir behaviour, physiology and extinction; i.e., their palaeobiology. Whereasthe first approach was largely developed in South America beginning about thesecond half of the 19th century due to the intellectual influence ofFlorentino Ameghino, palaeobiology became a much more recent line of work, inapparent relation to innovations in methodology and technology. Thiscontribution provides an overview of recent contributions on the palaeobiologyof Pleistocene fossil mammals of South America as attempts to provide answers for Darwin's questions.Durante los dos añosque Charles Darwin estuvo en América del Sur no sólo se deslumbró con laprofusa vegetación de Brasil, si no también con los gigantescos mamíferospleistocenos que colectó en áreas más secas de Uruguay y en la pampa y la costapatagónica de Argentina.

    Darwinism, also called Darwinian Theory, is a theory of biological evolution developed by British biologist, Charles Darwin, in the middle of the 19th century, which is considered to be the most important landmark in the history of mankind. In literary criticism, it is a new trend to unscramble literary works from the aspect of Darwinism, which is called literary Darwinism. The objective of this paper is to make a brief survey on the Darwinism manifested in Sam Shepard' s family trilogy from a particular point of view of literary Darwinism, aiming to analyze the fatality of the characters.%随着比较文学的发展壮大,跨学科研究成为文学研究的新亮点,达尔文主义也随之被赋予了强烈的人文色彩,出现了利用进化论的观点剖析文学作品的研究,达尔文文学主义也逐渐成为文学批评研究领域的新方向。本文运用文学达尔文主义理论对当代美国最富影响的剧作家萨姆.谢泼德的家庭三部曲进行解读,旨在剖析剧中人物的悲剧宿命。

    Full Text Available The Agua de la Zorra area (near Uspallata, Mendoza, Argentina is one of the best renowned fossil localities of the country because of its spectacular in situ fossil forest. This forest was discovered by Charles Darwin in 1835, who described this forest as monotypic and assigned it a Tertiary age. Nowadays, this fossil locality is known as the Darwin Forest. Over a century and a half later it was reinterpreted as a mixed Middle Triassic forest and a new fossil monotypic palaeocommunity of horsetails was discovered. This palaeovegetation is included in the Paramillo Formation (i.e., lower section the Potrerillos Formation of northwestern Cuyo Basin, Mendoza province (69°12' W and 32°30' S. The sediments were deposited in a sinuous fluvial system, in which channel-filling sand bodies were associated with mud-dominated floodplain deposits. The palaeoforest grew on an andisol soil that developed on volcaniclastic floodplain deposits. It had a density of 427 -759 trees per hectare, and was constituted by conifers and corystosperms distributed in two arboreal strata. The highest reached 20-26 m tall, and was dominated by corystosperms, but it also included the tallest conifers. The second stratum, mainly composed of conifers, ranged between 16-20 m tall. The forest has also emergent corystosperms, which reached 30 m tall. The understorey was composed of ferns. Growth ring anatomy suggests that conifers could have had an evergreen habit. Structure of vegetation, growth ring analyses and sedimentation suggest that the forest developed under dry, subtropical, and strongly seasonal conditions.El área de Agua de la Zorra (cerca de Uspallata, Mendoza, Argentina es uno de los sitios fósiles más espectaculares y renombrados del país porque aflora un bosque in situ.

    Full Text Available In1833 during his journey across the Buenos Aires Pampas, Charles Darwin madeobservations that reflected his thoughts on two major landscape units, Pampa interserrana and Pampa deprimida, later identified byother authors. Darwin grouped the Pampean sediments into a single unit, the PampeanFormation, based upon the lithological homogeneity and the large extensionof the deposits; the unit was thought to be of estuarine-marine origin andattributed to the Recent Epoch considering the paleontological content(vertebrates and mollusks. At present, the Pampean sedimentary succession,which accumulated approximately during the last 11-12 Ma, is interpreted as a pedosedimentarysequence due to the ubiquity of pedogenetic features throughout the deposits.Four main subcycles of sedimentation are identified related to reactivations ofthe Pampean landscape. At a regional scale, the outcrop distribution of Pampeansediments of different ages suggests the dominance of more stable conditionssince the late Miocene-Pliocene in a vast area of Pampa interserrana, documented by theformation of calcretes. However, sedimentation during the latePliocene-Pleistocene was active within the domain of the Salado tectonic basin andSierras de Tandil. The regional disparity shown by the Pampean stratigraphicrecord reveals the major morphostructural differences of its basement.Durante su viaje por la Pampa bonaerense en 1833 CharlesDarwin efectuó observaciones que reflejaban las dos grandes unidades de paisajeposteriormente reconocidas en la región, la Pampa interserrana y la Pampadeprimida.

    Cities are responsible for the majority of energy consumption on the planet. As a consequence, researches regarding energy use in urban context have been increasing for the last decades. Recently the interrelationship between city, energy consumption and urban microclimate appeared as a key component of urban sustainability. To be accurate, those studies must take into account a multidisciplinary urban context and modelling tools need high definition data. Nevertheless, at the city scale, input data is either imprecise or only available for small areas. In particular, there is a lack of information about buildings footprints, roofs sloping, envelope materials, etc. Moreover, the existing data do not allow researchers to explore prospective issues such as climate change or future urban development. In this sense, we developed a new tool called GENIUS (GENerator of Interactive Urban blockS) to build high definition and evolutionary maps from available databases. GENIUS creates maps composed of archetypical neighbourhood coming as shape-files of polygons with additional information (height, age, use, thermal insulation, etc.). Those archetypical neighbourhoods come to seven types of urban blocks that can be found in most European cities. Those types can be compared with Stewart and Oke Local Climate Zones (LCZ). The first step of our method is to transform an existing map into an 'archetypical map'. To do this, the urban database of the IGN (French Geographical Institute) was used. The maps were divided into cells of 250 meters resolution. For each cell, about 40 morphological indicators were calculated. Seven groups of blocks were then identified by means of Principal Component Analysis. GENIUS databases are also able to evolve through time. As a matter of fact, the initial map is transformed, year after year, by taking into account changes in density and urban history. In that sense, GENIUS communicates with NEDUM, a model developed by the CIRED (International

  20. Group adaptation, formal darwinism and contextual analysis.

    Okasha, S; Paternotte, C

    2012-06-01

    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.

Such an outlook is a state of the art of thecurrent understanding of the Late Miocene-Holocene history in the southwestern Pampas (Argentina. Multidisciplinaryresults were integrated in a chronosequence chart synthesizing the suggestedspace-time correlation of the recognized events. Some of the studied localitiescovering the whole time interval represented in the area were arranged in thischart in a hypothetical E-W line crossing the Río Sauce Grande basin and thesurrounding highlands. This line is also approximately the one followed in partby Darwin when riding from Bahía Blanca to Tapalqué (Tapalguenas he crossed the region toward the Río Sauce. Paleoenviromental andpaleoclimatic inferences for the last 10m.y. are also given. Paleontologicalstudies included vertebrates, ostracods and palynomorphs. Many of the resultsof these investigations are the answers to Darwin's question when he first visitedthe area.

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

    Directory of Open Access Journals (Sweden)

    J. S. Buckeridge

    2010-02-01

    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

    2013-05-01

    S-Genius is a new universal scatterometry platform, which gathers all the LTM-CNRS know-how regarding the rigorous electromagnetic computation and several inverse problem solver solutions. This software platform is built to be a userfriendly, light, swift, accurate, user-oriented scatterometry tool, compatible with any ellipsometric measurements to fit and any types of pattern. It aims to combine a set of inverse problem solver capabilities — via adapted Levenberg- Marquard optimization, Kriging, Neural Network solutions — that greatly improve the reliability and the velocity of the solution determination. Furthermore, as the model solution is mainly vulnerable to materials optical properties, S-Genius may be coupled with an innovative material refractive indices determination. This paper will a little bit more focuses on the modified Levenberg-Marquardt optimization, one of the indirect method solver built up in parallel with the total SGenius software coding by yours truly. This modified Levenberg-Marquardt optimization corresponds to a Newton algorithm with an adapted damping parameter regarding the definition domains of the optimized parameters. Currently, S-Genius is technically ready for scientific collaboration, python-powered, multi-platform (windows/linux/macOS), multi-core, ready for 2D- (infinite features along the direction perpendicular to the incident plane), conical, and 3D-features computation, compatible with all kinds of input data from any possible ellipsometers (angle or wavelength resolved) or reflectometers, and widely used in our laboratory for resist trimming studies, etching features characterization (such as complex stack) or nano-imprint lithography measurements for instance. The work about kriging solver, neural network solver and material refractive indices determination is done (or about to) by other LTM members and about to be integrated on S-Genius platform.

  12. Electron billiards: einselection and quantum Darwinism

    International Nuclear Information System (INIS)

    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)

  13. Obituary: Charles Latif Hyder, 1930-2004

    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

  16. Darwin at Orchis Bank: Selection after the Origin.

    Science.gov (United States)

    Tabb, Kathryn

    2016-02-01

    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.

    2013-06-01

    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? PMID:23961688

    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 136-Xe, as well as measure the low-energy solar neutrino flux with <1% precision, observe coherent neutrino-nucleus interacti...

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

    2014-08-01

    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. PMID:23835785

  6. Darwin and the origin of interspecific genetic incompatibilities.

    Science.gov (United States)

    Presgraves, Daven C

    2010-12-01

    Darwin's Origin of Species is often criticized for having little to say about speciation. The complaint focuses in particular on Darwin's supposed failure to explain the evolution of the sterility and inviability of interspecific hybrids. But in his chapter on hybridism, Darwin, working without genetics, got as close to the modern understanding of the evolution of hybrid sterility and inviability as might reasonably be expected. In particular, after surveying what was then known about interspecific crosses and the resulting hybrids, he established two facts that, while now taken for granted, were at the time radical. First, the sterility barriers between species are neither specially endowed by a creator nor directly favored by natural selection but rather evolve as incidental by-products of interspecific divergence. Second, the sterility of species hybrids results when their development is "disturbed by two organizations having been compounded into one." Bateson, Dobzhansky, and Muller later put Mendelian detail to Darwin's inference that the species-specific factors controlling development (i.e., genes) are sometimes incompatible. In this article, I highlight the major developments in our understanding of these interspecific genetic incompatibilities--from Darwin to Muller to modern theory--and review comparative, genetic, and molecular rules that characterize the evolution of hybrid sterility and inviability.

    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.

  8. Darwin and Lotka: Two Concepts of Population

    Directory of Open Access Journals (Sweden)

    Philip Kreager

    2009-10-01

    Full Text Available Population was the subject of two major conceptual developments in the second quarter of the 20th century. Both were inspired by evolutionary biology. Lotka developed a mathematics of evolution in human and other species by analogy to thermodynamic models. His theory followed demographic practice in treating populations as closed units, commonly macro-scale, and in inferring underlying processes of change from aggregate outcomes. In contrast, the evolutionary synthesis - a collaborative product of research in experimental and population genetics, natural history, and related fields of biology - followed Darwin in insisting that close observation of small-scale population processes and local environments is necessary to understand population change. Because gene-environment interactions rely on expanding and contracting networks of individuals, the populations in question are by nature open. Despite the apparent conflict between these positions, the synthesis broke new ground in the history of population thought by showing how the two approaches could be combined. Demography, however, moved away from evolutionary and population biology as a source of theory in the early post-war era, and this conceptual redevelopment of population was scarcely remarked upon. More recently, the tremendous development of genetics has recalled demographers' attention to evolutionary theory as an inescapable element of modern population thought. This paper provides a historical introduction to mid-20th-century developments in Darwinian population thinking, and the implications of its dual conceptualisation of population for demography. Its potential importance extends beyond the problem of gene-environment interactions to many aspects of social network analysis.

  9. The challenge of instinctive behaviour and Darwin's theory of evolution.

    Science.gov (United States)

    Gordillo-García, Alejandro

    2016-03-01

    In the Origin of Species (1859), Darwin argued that his revolutionary theory of evolution by natural selection represented a significant breakthrough in the understanding of instinctive behaviour. However, many aspects in the development of his thinking on behavioural phenomena indicate that the explanation of this particular organic feature was by no means an easy one, but that it posed an authentic challenge - something that Darwin himself always recognized. This paper explores Darwin's treatment of instincts within his theory of natural selection. Particular attention is given to elucidate how he tackled the difficulties of explaining instincts as evolving mental features. He had to explain and demonstrate its inheritance, variation, and gradual accumulation within populations. The historical and philosophical aspects of his theory are highlighted, as well as his study of the case in which the explanation of instincts represented a 'special difficulty'; that is, the sterile castes of social insects.

    Directory of Open Access Journals (Sweden)

    Corral Cuartas Álvaro

    2009-12-01

    Full Text Available La teoría de la selección natural propuesta por Charles Darwin en su obra El Origen de las Especies no sólo colocó las bases para una explicación coherente de los hechos fundamentales de la biología (el origen común de los seres vivos, la diversidad de individuos y especies y la transmisión de características hereditarias, sino que además introduce maneras nuevas de hacer filosofía. La teoría de la selección natural hace superflua cualquier posibilidad de apelar a explicaciones de tipo finalista en la ciencia. Desde Aristóteles se conocen cuatro tipos de causa: la material, la formal, la eficiente y la final. Aunque la causa eficiente es el paradigma de explicación por excelencia de las ciencias empíricas, la causa final sigue desempeñando un papel explicativo, por cuanto parece estar arraigada en nuestra estructura humana de pensamiento y la tendencia a presentar explicaciones finalistas sigue siendo recalcitrante. Quizá por estar los seres humanos tan familiarizados con la complejidad inherente a los procesos de diseño en las artes y en la técnica, suponemos por vía de analogía que la naturaleza en su complejidad exige la presencia y acción de un diseñador inteligente. Kant en la Crítica de la facultad de juzgar hace una defensa del carácter “irrenunciable” de este modelo explicativo. Para controvertir esta opinión, me apoyaré, en recientes investigaciones de Richard Dawkins y de otros biólogos contemporáneos para mostrar con la evolución de ojos en la naturaleza que el surgimiento de órganos de alta complejidad puede ser explicado sin

  11. Darwin and sexual selection: One hundred years of misunderstanding.

    Science.gov (United States)

    Veuille, Michel

    2010-02-01

    Darwin's book on the Descent of Man and Selection in Relation to Sex (1871) is often viewed as the continuation of The Origin of Species published 12 years earlier (1859), both because of the implicit parallelism between natural selection and sexual selection, and because Darwin himself presents the book as developing a subject (man) which he intentionally omitted in the Origin. But the Descent can also be viewed as the continuation of his book on Variation published three years earlier (1868). Firstly because Darwin's hypothesis of pangenesis links the selection process to the origin of variation through use and disuse, an idea underlying his speculations on the origin of moral sense in humans. Second because like the action of the horticulturist on his domestic crops, sexual selection exerted by one sex on the other sex can develop fancy traits that are not easily accounted for by their utility to the selected organism itself, such as artistic taste, pride, courage, and the morphological differences between human populations. These traits are difficult to reconcile with pangenesis. They add up to other contradictions of the book possibly resulting from Darwin's erroneous inference about the mechanism of inheritance, like those on the determination of sex-ratio, or the confusion between individual adaptation and the advantage to the species. These inconsistencies inaugurate a weakening of the Darwinian message, which will last 50 years after his death. They contributed to the neglect of sexual selection for a century. Darwin however maintained a logical distinction between evolutionary mechanisms and hereditary mechanisms, and an epistemological distinction between evolutionary theory and Pangenesis hypothesis. In the modern context of Mendelian genetics, Darwin's sexual selection retrospectively appears as luminous an idea in its pure principle as natural selection, even though the mechanisms governing the evolution of sexual choice in animals remain largely

  12. DARWIN Y LA PARADOJA DE LAS ISLAS VACÍAS Darwin and the Empty Island Paradox

    JUAN FELIPE BLANCO

    Full Text Available Aunque se conoce el interés y fascinación de Darwin por la naturaleza marina a través de sus tratados sobre arrecifes coralinos, islas oceánicas y balanos, poco se comenta sobre los múltiples ejemplos dulceacuícolas que él utilizó para plantear la -teoría de la migración- dentro de -El origen-. Ésta plantea que la fauna y la flora se -dispersan- desde los continentes hacia las islas oceánicas. Sin embargo, en la islas muy alejadas de los centros de origen la probabilidad de colonización es muy baja y por lo tanto solo se encuentra una fracción de la biota continental, pudiendo considerarse en algunos casos -vacías-. Aunque las corrientes de agua de dichas islas también se consideran -vacías-, Darwin propuso un mecanismo para explicar la presencia de peces -dulceacuícolas- en las mismas, y por lo tanto no podrían considerarse -vacías-, lo cual plantea una paradoja. El mecanismo planteado por él coincide con el ciclo de vida conocido actualmente como diádromo en el cual los individuos de muchas especies de peces, camarones y gasterópodos requieren de aguas marinas y dulces para completar su desarrollo. La diadromía es una convergencia evolutiva que apareció en diferentes linajes a partir de ancestros tanto marinos como dulceacuícolas. En este ensayo se discute la evolución de la fauna dulceacuícola insular, sus implicaciones ecológicas y evolutivas, y algunos modelos experimentales. Finalmente, se discute sobre los impactos de las represas en islas tropicales y subtropicales sobre las especies diádromas.Although Darwin's fascination and interest on marine nature are well known due to his treatises about coral reefs, oceanic islands, and barnacles, little is commented about the many -freshwater- examples that he provided for supporting -The Migration Theory- in his book -The Origin of the Species-.

    Full Text Available Desde que hiciera su aparición El origen de las especies y empezara adifundirse la teoría darwinista de la evolución, ésta suscitó las más encendidaspolémicas. Desde diversos sectores, partieron en mayor o en menorgrado ataques muy duros, algunos de los cuales no carecían de un sólidofundamento. Pero los golpes más violentos llegaron desde el terreno dela religión, que se sintió particularmente afectada. Aún hoy, cuando celebramosel bicentenario del nacimiento de Darwin, las aguas no parecenhaberse aquietado alrededor suyo. Todavía, algunos influyentes sectoresfundamentalistas siguen considerándola, inclusive en su versión actual,la teoría sintética de la evolución, como un peligro para la fe religiosa.Los ataques se producen bajo la forma de un amplio abanico de modalidades:desde un rechazo rotundo en defensa de los textos bíblicos hastauna descalificación supuestamente científica que, aparentando situarseen una perspectiva no religiosa, cuestiona los fundamentos de la teoría ypropone la doctrina del llamado diseño inteligente.A pesar de todo, debemos reconocer que, actualmente, a 150 añosde la publicación de El origen, la situación ha variado.

  19. Darwin and Mendel: who was the pioneer of genetics?

    Science.gov (United States)

    Liu, Yongsheng

    2005-01-01

    Although Mendel is now widely recognized as the founder of genetics, historical studies have shown that he did not in fact propose the modern concept of paired characters linked to genes, nor did he formulate the two "Mendelian laws" in the form now given. Furthermore, Mendel was accused of falsifying his data, and Mendelism has been met with scepticism because of its failure to provide scientific explanation for evolution, to furnish a basis for the process of genetic assimilation and to explain the inheritance of acquired characters, graft hybridization and many other facts. Darwin was the first to clearly describe almost all genetical phenomena of fundamental importance, and was the first to present a developmental theory of heredity--Pangenesis, which not only greatly influenced many subsequent theories of inheritance, particularly those of de Vries, Galton, Brooks and Weismann, but also tied all aspects of variation, heredity and development together, provided a mechanism for most of the observable facts, and is supported by increasing evidence. It has also been indicated that Darwin's influence on Mendel, primarily from The Origin, is evident. The word "gene" was derived from "pangen", itself a derivative of "Pangenesis" which Darwin had coined. It seems that Darwin should have been regarded as the pioneer, if not of transmissional genetics, of developmental genetics and molecular genetics. PMID:16180199

  20. Darwin, Veblen and the problem of causality in economics.

    Science.gov (United States)

    Hodgson, G M

    2001-01-01

    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. PMID:12472063

    Full Text Available Este trabajo expone la teoría democrática de Charles Taylor. Taylor defiende una concepción tocquevilliana de la democracia que opone tanto al minimalismo democrático neoliberal, como al republicanismo democrático de Rousseau. Primero, consideramos su crítica a la democracia neoliberal y sus determinaciones conceptuales: atomismo, libertad negativa, procedimentalismo y bienes convergentes. Segundo, defiramos la "tesis republicana" de Taylor que presenta como la condición de posibilidad de una sociedad libre y autogobernada. Tercero, examinamos la desavenencia de Taylor con la homogeneización de intereses que el marxismo hereda de Rousseau. Finalmente, exploramos las posibilidades de aplicación de la teoría democrática de Taylor. Estudiamos su posible aplicación a dos economías en transición: Brasil y Chile.This paper examines Charles Taylor's democratic theory. Taylor defends a republican conception of democracy, which he opposes both to neoliberal democratic minimalism and to Rousseau and democratic republicanism. First, we consider his critique of neoliberal democracy and its conceptual determinations: atomism, negative freedom, proceduralism and. convergent goods. Second, we define Taylor's "republican thesis" which he presents as the condition of the possibility of agrees and self-governed society. Third, we study Taylor's disagreement with the homogenization of interests that Marxism inherits from Rousseau. Finally, we explore the possibility of applying Taylor's democratic theory. The case of Brazil and Chile are analyzed for this purpose.

  6. Genius [corrected] without the "Great Man": new possibilities for the historian of psychology.

    Science.gov (United States)

    Ball, Laura C

    2012-02-01

    The Carlylian style of history, more commonly known as the "Great Man" approach, presented the "genius" as an individual worthy of celebration: history as hero worship. This style, which characterized the first wave of the history of psychology, has gone out of historiographic fashion. In its place is the "new history," which is marked by its external focus and privileging of social factors and cultural context in its explanations. This shift in historiographic sensibilities has also led to a revision in the appropriate subject matter for psychologist-historians. This article argues, in contrast, that it is possible to study eminent individuals without resorting to hagiography, and it presents various methods that could be used for this purpose. The aim of such an endeavor is to create a space for critically and historically informed perspectives on greatness and to suggest a reconsideration of the value of an "historical psychology".

    Ludwig van Beethoven is nowadays considered to be one of the greatest composers in the history of music and his myth-like reputation is enhanced by his deafness; however, deafness was not the only condition which affected his genius. Due to the many lamentations contained in his letters about continuously recurring health problems, various attempts at an interpretation of Beethoven's personality have been undertaken. These included psychoanalytical considerations with respect to his father-mother relationship and also diagnostic attempts with reference to the symptoms of a possible borderline personality syndrome. The aim of this article is to comprehensively analyze the diseases of the patient Beethoven from the perspective of specialized medical disciplines based on new research results, to summarize various discipline-specific considerations and to make a contemporary assessment from the viewpoint of current scientific results.

    How can leaders build an organization that is capable of innovating continually over time? By creating a community that is both willing and able to innovate. To be willing, the community must share a sense of purpose, values, and rules of engagement. When Luca de Meo was Volkswagen's head of marketing communication, he fostered a sense of purpose in his team by asking its members to reflect on what being part of VW meant to them; strengthened their shared values by encouraging them to use the brand's three components-innovation, responsibility, and value-to guide their work; and built significant responsibility and autonomy into their rules of engagement. To be able, companies must generate ideas through discourse and debate; experiment quickly, reflect, and adjust; and make decisions that combine disparate and even opposing ideas. Bill Coughran, an SVP of engineering at Google, employed these capabilities both to solve the company's near-term data storage needs and to make progress toward a next-generation solution.

  12. Macroevolution via secondary endosymbiosis: a Neo-Goldschmidtian view of unicellular hopeful monsters and Darwin's primordial intermediate form.

    Science.gov (United States)

    Kutschera, U; Niklas, K J

    2008-08-01

    Seventy-five years ago, the geneticist Richard Goldschmidt hypothesized that single mutations affecting development could result in major phenotypic changes in a single generation to produce unique organisms within animal populations that he called "hopeful monsters". Three decades ago, Sarah P. Gibbs proposed that photosynthetic unicellular micro-organisms like euglenoids and dinoflagellates are the products of a process now called "secondary endosymbiosis" (i.e., the evolution of a chloroplast surrounded by three or four membranes resulting from the incorporation of a eukaryotic alga by a eukaryotic heterotrophic host cell). In this article, we explore the evidence for Goldschmidt's "hopeful monster" concept and expand the scope of this theory to include the macroevolutionary emergence of organisms like Euglena and Chlorarachnion from secondary endosymbiotic events. We argue that a Neo-Goldschmidtian perspective leads to the conclusion that cell chimeras such as euglenids and dinoflagellates, which are important groups of phytoplankton in freshwater and marine ecosystems, should be interpreted as "successful monsters". In addition, we argue that Charles Darwin had euglenoids (infusoria) in mind when he speculated on the "primordial intermediate form", although his Proto-Euglena-hypothesis for the origin of the last common ancestor of all forms of life is no longer acceptable.

  13. Reconstructing Anaximander's biological model unveils a theory of evolution akin to Darwin's, though centuries before the birth of science.

    Science.gov (United States)

    Trevisanato, Siro Igino

    2016-08-01

    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.

  4. Generic emergence of classical features in quantum Darwinism

    Science.gov (United States)

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

    2015-08-01

    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.

  6. The Darwin-Breit magnetic interaction and superconductivity

    CERN Document Server

    Essen, Hanno

    2013-01-01

    A number of facts indicating the relevance of the Darwin magnetic interaction energy in the superconducting phase are pointed out. The magnetic interaction term derived by Darwin is the same as the, so called, Breit term in relativistic quantum mechanics. While this term always is a small perturbation in few body systems it can be shown to be potentially dominating in systems of large numbers of electrons. It is therefore a natural candidate in the explanation of emergent phenomena---phenomena that only occur in sufficiently large systems. The dimensionless parameter that indicates the importance of the magnetic energy is the number of electrons times the classical electron radius divided by the size of the system. The number of electrons involved are only the electrons at the Fermi surface; electrons with lower energy cannot contribute to current density and thus not to the magnetic field. The conventional understanding of superconductivity has always been problematic and no really reductionistic derivation ...

    Balon, Eugene K

    2004-01-01

    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). PMID:15612191

    Full Text Available Hans RotheBreaking through History. Genius and Literature among Slavs without a State in the 19th CenturyWithin a broad comparative framework, the Author analyzes some of the main patterns of the development of national self-consciousness and identity among the peoples of Eastern Europe between the 1830s and 1850s. He discusses the general assumption that the French Revolution played a major role in the awakening of national consciousness in the Slavic (and the Hungarian cultures, and that an important part of the longing for self-determination was connected with the idea that Slavs where understood as a united family of peoples or even as one nation. The Author then addresses three main topics. It is generally accepted that in some countries it was primarily poetic geniuses who brought about a dramatic breakthrough in national consciousness thanks to the fact that their works were written in their own language (examples include Mickiewicz, Puškin, Ševčenko, Prešeren and others. Nonetheless, the importance of learning, academic training, gathering historical knowledge and folk tradition as primary sources of national consciousness should not be underestimated. These elements, the Author maintains, are connected rather with traditional ideas and mentality (and with Herder’s way of thinking, than with ‘revolutionary’ innovation. Unlike the French model of development that followed the 1789 revolution and largely identified nation with revolution, Slav peoples were confronted with their belonging to multiethnic and plurilingual political structures: they were either dominant powers (such as Russia, which dominated many other peoples or were dominated by ‘others’. From several points of view, Herder’s idea of Slav unity was often more of a hindrance than a way out for the definition of national unity. This was true for the dominated peoples, but for Russians too, although, politically speaking, they were effectively the only real

La teoría de la selección natural hace superflua cualquier posibilidad de apelar a explicaciones de tipo finalista en la ciencia. Desde Aristóteles se conocen cuatro tipos de causa: la material, la formal, la eficiente y la final. Aunque la causa eficiente es el paradigma de explicación por exce-lencia de las ciencias naturales, la causa final sigue desempeñando un papel explicativo, por cuanto parece estar arraigada en nuestra estructura humana de pensamiento y la tendencia a presentar explicaciones finalistas sigue siendo recalcitrante. Quizá por estar los seres humanos tan familiarizados con la complejidad inherente a los procesos de diseño en las artes y en la técnica y quizá por la circunstancia de que los seres humanos organizamos casi todas nuestras acciones en torno a propósitos, es decir, a la definición de unos fines para los cuales buscamos unos medios, suponemos por vía de analogía que la naturaleza en su complejidad exige la presencia y acción de un diseñador inteligente. Kant en la Crítica de la facultad de juzgar hace una defensa del carácter "irrenunciable al género humano" de este modelo explicativo. Para contro-vertir esta opinión milenaria, me apoyaré, en investigaciones recientes de Richard Dawkins y de otros biólogos contemporáneos para mostrar con la evolución de ojos en la naturaleza que el surgimiento de órganos de alta complejidad puede ser explicado sin problema con la teoría de la selección natural propuesta por Darwin en 1859.Darwin’s theory of natural selection in The Origin of Species not only laid

  14. Dave Eggers's a heartbreaking work of staggering genius: memoir as a "pain-relief device".

    2011-10-01

    Dave Eggers's memoir is an important addition to the tradition of autobiography in America, and offers significant contributions to our understanding of creativity, sublimation, and the psychology of the memoir-writing process. A Heartbreaking Work of Staggering Genius is really two books--an autobiographical narrative about unbearable suffering, and a book of psychoanalytic commentary on the challenges of writing a memoir about catastrophic loss and trauma. The main narrative suggests the psychological resilience it takes to contain unbearable suffering. The metanarrative renders transparent the mind of someone who is both remembering his losses and constantly reflecting upon the process of writing about them. Eggers's identification with authorship, rather than bereavement or traumatization, may have played an important role in containing his affect and his sense of self when the heartbreaking events were originally unfolding. But a price is paid when a son uses his art to construct a new identity as an author--unconscious conflicts, primitive affect, anxieties about failing, as well as guilt about succeeding--consequences often missed by readers. Heartbreaking is a palimpsest, a story about story-telling superimposed on tales of death and survival, but its messages will be missed unless all its parts are preserved when being read or studied.

    Peter Watson's virtuoso sweep through modern German thought and culture, from 1750 to the present day, will challenge and confound both the stereotypes the world has of Germany and those that Germany has of itself. From the end of the Baroque era and the death of Bach to the rise of Hitler in 1933, Germany was transformed from a poor relation among Western nations into a dominant intellectual and cultural force—more creative and influential than France, Britain, Italy, Holland, and the United States. In the early decades of the twentieth century, German artists, writers, scholars, philosophers, scientists, and engineers were leading their freshly unified country to new and unimagined heights. By 1933, Germans had won more Nobel Prizes than any other nationals, and more than the British and Americans combined. Yet this remarkable genius was cut down in its prime by Adolf Hitler and his disastrous Third Reich—a brutal legacy that has overshadowed the nation's achievements ever since.

    2011-11-01

    Full Text Available Today the understanding of mathematics is critical in an increasingly technological age. Teachers must play an important role to ensure that all students display confidence in their ability to do mathematics. Often gifted students of mathematics can be made to feel bad by their peers just because they know mathematics and things come easily to them. Children’s and adolescent literature has now been recognised as a means of teaching mathematics to students through the use of stories to make the mathematics concepts relevant and meaningful. Literature can also be used as a form of therapy to reach students who may be frustrated with children picking on them for being good at mathematics. Story and picture books such as Counting on Frank, Math Curse and A Gebra Named Al are now available to use in the classroom as forms of bibliotherapy in helping students come to terms with issues relating to mathematics that haunt them. In this article we discuss the phenomenon of dumbing down by the gifted population to fit in with their peers. We propose using reading and discussion (bibliotherapy to aid in preventing de-geniusing of mathematically gifted students.

  18. Double beta decay - physics beyond the standard model now, and in future (Genius)

    International Nuclear Information System (INIS)

    Nuclear double beta decay provides an extraordinarily broad potential to search for beyond standard model physics, probing already now the TeV scale, on which new physics should manifest itself. These possibilities are reviewed here. First, the results of present generation experiments are presented. The most sensitive one of them - the Heidelberg-Moscow experiment in the Gran Sasso - probes the electron mass now in the sub eV region and will reach a limit of ∝0.1 eV in a few years. Basing to a large extent on the theoretical work of the Heidelberg double beta group in the last two years, results are obtained also for SUSY models (R-parity breaking, sneutrino mass), leptoquarks (leptoquark-Higgs coupling), compositeness, right-handed W boson mass and others. These results are comfortably competitive to corresponding results from high-energy accelerators like TEVATRON, HERA, etc. Second, future perspectives of ββ research are discussed. A new Heidelberg experimental proposal (GENIUS) is presented which would allow to increase the sensitivity for Majorana neutrino masses from the present level of at best 0.1 eV down to 0.01 or even 0.001 eV. Its physical potential would be a breakthrough into the multi-TeV range for many beyond standard models. Its sensitivity for neutrino oscillation parameters would be larger than of all present terrestrial neutrino oscillation experiments and of those planned for the future. (orig.)

    Darwin spent much time and effort on the study of inherited diseases and the role of environment in disease development. To explain inherited diseases and a considerable variety of other hereditary phenomena, he formulated a Pangenesis hypothesis, assuming that cells could shed many kinds of molecules capable of diffusion from cell to cell, circulation throughout the body, incorporation into recipient cells, and transmission from parents to offspring. His Pangenesis is now supported by the discovery of circulating DNA, mobile RNAs and prions, and might provide an alternative molecular mechanism underlying the inherited diseases. PMID:26836487

    Evolution of species is a complex phenomenon. Some theoretical models take into account evolution of species, like the Bak-Sneppen model that obtain punctuated equilibrium from self-organized criticality and the Penna model for biological aging that consists in a bit-string model subjected to aging, reproduction and death. In this work we propose a simple model to study different scenarios used to simulate the evolution of species. This model is based on Darwin's ideas of evolution. The present findings show that punctuated equilibria and stasis seem to be obtained directly from the mutation, selection of parents and the genetic crossover, and are very close to the fossil data analysis.

First we describe how he used various nineteenth century categories of inheritance: atavism, constitution, genealogy, prepotency and morbid tendency. Afterward, by identifying in his texts these categories it is shown that his investigation on the transformation of species was conceptually linked with the problem of inheritance but his interpretation differed with hereditarism, the dominant point of view from which the history of the research on inheritance has been written.En este escrito revisamos la forma en la que Darwin interpretó algunas nociones del problema de la herencia.

  12. Future perspectives of double beta decay and dark matter search - GENIUS

    International Nuclear Information System (INIS)

    The recent results from the HEIDELBERG-MOSCOW experiment have demonstrated the large potential of double beta decay to search for new physics beyond the standard model. To increase by a major step the present sensitivity for double beta decay and dark matter search, much bigger source strengths and much lower backgrounds are needed than used in experiments under operation at present or under construction. We describe here a project which would operate one tonne of 'naked' enriched germanium-detectors in liquid nitrogen as shielding in an underground set-up (GENIUS). It improves the sensitivity of neutrino masses to 0.01 eV. A 10 tonne version would probe neutrino masses even down to 10-3 eV. The first version would allow us to test the atmospheric neutrino problem, the second at least part of the solar neutrino problem. Both versions would allow, in addition, significant contributions to testing several classes of GUT models. These are especially tests of R-parity breaking and conserving supersymmetry models - including sneutrino masses - leptoquark masses and mechanism and right-handed W-boson masses comparable with LHC. The second issue of the experiment is the search for dark matter in the universe. The full MSSM parameter space for the prediction of neutralinos as dark matter particles could be covered already in a first step of the full experiment using only 100 kg of 76Ge or even of natural Ge making the experiment competitive with LHC in the search for supersymmetry.

  14. An Ottoman response to Darwinism: İsmail Fennî on Islam and evolution.

    Bilgili, Alper

    2015-12-01

    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.

  18. From Darwin to Internet at the speed of light

    Science.gov (United States)

    2002-11-01

    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

This achievement, nevertheless, was obtained by a way that Kant could not foresee and that Haeckel could not understand: Darwin came there showing that there was more natural science than that Newton, Kant and Haeckel could conceive.

    Klapdor-Kleingrothaus, H V

    2001-01-01

    Double beta decay is indispensable to solve the question of the neutrino mass matrix together with nu oscillation experiments. The most sensitive experiment for eight years-the HEIDELBERG-MOSCOW experiment in Gran-Sasso-already now, with the experimental limit of (m/sub nu /)<0.26 eV excludes degenerate nu mass scenarios allowing neutrinos as hot dark matter in the Universe for the small angle MSW solution of the solar neutrino problem. It probes cosmological models including hot dark matter already now on the level of future satellite experiments MAP and PLANCK. It further probes many topics of beyond standard model physics at the TeV scale. Future experiments should give access to the multiTeV range and complement on many ways the search for new physics at future colliders like LHC and NLC. For neutrino physics GENIUS will allow to test almost all neutrino mass scenarios allowed by the present neutrino oscillation experiments. At the same time GENIUS will cover a wide range of the parameter space of pred...

    2010-06-01

    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.

    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.

  8. Consequence etiology and biological teleology in Aristotle and Darwin.

    2008-12-01

    Aristotle's biological teleology is rooted in an epigenetic account of reproduction. As such, it is best interpreted by consequence etiology. I support this claim by citing the capacity of consequence etiology's key distinctions to explain Aristotle's opposition to Empedocles. There are implications for the relation between ancient and modern biology. The analysis reveals that in an important respect Darwin's account of adaptation is closer to Aristotle's than to Empedocles's. They both rely on consequence etiological considerations to evade attributing the purposiveness of organisms to chance. Two implications follow: (l) Darwinian explanations of adaptation are as teleological as Aristotle's, albeit differently; and (2) these differences show how deeply resistant Aristotle's version of biological teleology is to descent from a common ancestor.

  10. On Darwin's 'metaphysical notebooks'. II: "Metaphysics" and final cause.

    Science.gov (United States)

    Calabi, L

    2001-01-01

    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.

    2005-01-01

    The DARWIN mission is an Infrared free flying interferometer mission based on the new technique of nulling interferometry. Its main objective is to detect and characterize other Earth-like planets, analyze the composition of their atmospheres and their capability to sustain life, as we know it. DARWIN is currently in definition phase. This PhD work that has been undertaken within the DARWIN team at the European Space Agency (ESA) addresses two crucial aspects of the mission. Firstly, a DARWIN target star list has been established that includes characteristics of the target star sample that will be critical for final mission design, such as, luminosity, distance, spectral classification, stellar variability, multiplicity, location and radius of the star. Constrains were applied as set by planet evolution theory and mission architecture. Secondly, a number of alternative mission architectures have been evaluated on the basis of interferometer response as a function of wavelength, achievable modulation efficienc...

  14. The influence of James and Darwin on Cajal and his research into the neuron theory and evolution of the nervous system

    Directory of Open Access Journals (Sweden)

    Francisco Rômulo Monte Ferreira

    2014-01-01

    Full Text Available In this article we discuss the influence of William James and Charles Darwin on the thoughts of Ramón y Cajal concerning the structure, plasticity and evolution of the nervous system at the cellular level. Here we develop Cajal’s notion that neuronal theory is a necessary condition to explain the plasticity of neural connections. Although the roots of the term ‘plasticity’ in reference to neuroscience are not completely clear, Cajal was an important figure in the propagation and popularization of its use. It is true that he carried out a large number of studies throughout his career in favor of the neuronal theory, but perhaps one of the most interesting aspects of his studies was his innovative capacity to interpret structure as being the result of evolutionary mechanisms, i.e., natural selection. This capacity would ultimately lead Cajal to the conclusion that, in relation to the histology of the nervous system, such selection occurs in the establishment of connections between cells.

  15. Darwin and his pigeons. The analogy between artificial and natural selection revisited.

    Science.gov (United States)

    Theunissen, Bert

    2012-01-01

    The analogy between artificial selection of domestic varieties and natural selection in nature was a vital element of Darwin's argument in his Origin of Species. Ever since, the image of breeders creating new varieties by artificial selection has served as a convincing illustration of how the theory works. In this paper I argue that we need to reconsider our understanding of Darwin's analogy. Contrary to what is often assumed, nineteenth-century animal breeding practices constituted a highly controversial field that was fraught with difficulties. It was only with considerable effort that Darwin forged his analogy, and he only succeeded by downplaying the importance of two other breeding techniques - crossing of varieties and inbreeding - that many breeders deemed essential to obtain new varieties. Part of the explanation for Darwin's gloss on breeding practices, I shall argue, was that the methods of his main informants, the breeders of fancy pigeons, were not representative of what went on in the breeding world at large. Darwin seems to have been eager to take the pigeon fanciers at their word, however, as it was only their methods that provided him with the perfect analogy with natural selection. Thus while his studies of domestic varieties were important for the development of the concept of natural selection, the reverse was also true: Darwin's comprehension of breeding practices was moulded by his understanding of the working of natural selection in nature. Historical studies of domestic breeding practices in the eighteenth and nineteenth century confirm that, besides selection, the techniques of inbreeding and crossing were much more important than Darwin's interpretation allowed for. And they still are today. This calls for a reconsideration of the pedagogic use of Darwin's analogy too. PMID:22037999

  17. William Keith Brooks and the naturalist's defense of Darwinism in the late-nineteenth century.

    Nash, Richard

    2015-06-01

    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.

    The effect of biodiversity loss on ecosystem functioning is a relatively new research topic in ecology. The motivation for this research comes largely from current forecasts of ongoing loss of biodiversity. However, the intellectual link between biodiversity and ecosystem processes was first inferred by Darwin based on his Principle of Divergence. In the notes for his Big Species Book Darwin explicitly states that communities composed of organisms developed under “many and widely differing...

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

    Directory of Open Access Journals (Sweden)

    Kostas Kampourakis

    2015-10-01

    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.

    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.

    Goldsmith, P. F.

    2016-05-01

    Charles Townes is renowned for his work elucidating the structure of molecules through microwave spectroscopy and for his invention of the maser and the laser. He also had a lifelong interest in astronomy, and in the later portion of his remarkable and long career devoted himself to astronomical research, pioneering the study of molecules in interstellar space and the development of infrared spectroscopy, first from the ground and then from airborne facilities. His interest in high angular resolution, as well as high spectral resolution observations, led to development of the first infrared spatial interferometer employing coherent signal processing techniques. In this short review I will only touch on some of Townes' many scientific contributions, concentrating on astronomy, and will also give some personal thoughts about how he inspired students in their research, helping to make the "Townes Group" at the University of California, Berkeley, an ideal environment in which to start a career in research.

    2013-01-01

    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.

    Full Text Available Charles Bonnet syndrome occurs in visually impaired but cognitively normal individuals. This report describes a condition of vivid visual hallucination (phantom images in an 85-year-old conscious man, who had been blind by bilateral progressively worsening glaucoma. This common, but rarely reported, condition was managed by behavioral approach of repeated blinking, intermittent eyes closure, and reassurance. While emotional, mood and cognitive disorders need to be ruled out, the condition, though frightening to the afflicted, is benign and remediable with simple, inexpensive approach. Health workers managing people with terminal blindness should always ask for the presence of hallucinations from their patients to forestall a preventable distress resulting from wrong perception without visual stimulus.

    1981-06-01

    The Charles River Basin which was created by construction of a dam in 1910 has been stratified since that time with salt water intruding from Boston Harbor through a boat lock and leaky sluices. In order to eliminate nuisance conditions and fish kills caused by hydrogen sulfide from the anoxic bottom water, destratification by air-mixing was initiated in the spring of 1978. Six diffusers were installed on the bottom in the deep sections of the Basin and operated as necessary to induce sufficient circulation to maintain a minimum of 4.0 mg/1 dissolved oxygen throughout the water column. After two and a half years of operation, hydrogen sulfide has been eliminated and water quality has generally improved in the area of the Basin influenced by the diffusers.

    Full Text Available This article introduces some of the practical and theoretical implications of a local development strategy. The strategy is based on the synergy between a local constructed patrimony and the local enogastronomic patrimony. Departing from a theoretical framework, the article starts by describing and analyzing the Villa dei Sapori project, developed in the context of an architectonic complex in Italy. The complex, Villa Sorra, is located in the Modena region. The concept of situated development is defined through this case study. It is also interpreted through the experience of its manager. We arrive at the conclusion that the creation of territorial valorization strategies, in a situated perspective, rely on the possibility of the existence of a dialogic relationship between the project author and the genius loci (the “spirit of the place”.O artigo apresenta as perspectivas teóricas e práticas de uma estratégia de desenvolvimento local, baseada na sinergia entre o patrimônio construído e enogastronômico local.

  9. BOOK REVIEW: Count Rumford: The Extraordinary Life of a Scientific Genius

    Brown, Neil

    2000-05-01

    Benjamin Thompson, Count Rumford, is best known for the cannon boring experiments that confirmed to him that heat was what we would call molecular motion. Some will also know him as the founder of the Royal Institution in London. He was, however, a much more colourful character than these details suggest. Born in Massachusetts in 1753, he had an unremarkable childhood. He married a wealthy widow, who bore him a daughter. In the American War of Independence he sided with the British, and spent some time in England. At the end of the war he moved to Europe and contrived to become an aide to the Elector of Bavaria. Munich was the scene of his most solid achievements and of most of his scientific work. It was here he was ennobled as Count Rumford. He founded the Royal Institution in 1799, during a lengthy interlude in London, but almost from the start there was friction between Rumford and other backers. He spent most of the rest of his life in Paris, contracting a second marriage to the wealthy widow of the chemist Lavoisier. Ironically, Lavoisier had been a supporter of the alternative, caloric, theory of heat. The couple soon divorced and Rumford became increasingly reclusive, dying suddenly in 1814. The book cover describes Rumford as `scientist, soldier, statesman, spy'. He was all of those but not first rate at any of them. He was also an adventurer, a womaniser and a self-publicist with a habit of exaggerating his own accomplishments and a talent for acquiring honours and permanent pensions. His work on the nature of heat was significant, but to claim, as the title does, that he was a scientific genius is excessive. He was the first to provide real evidence for the kinetic theory of heat, and his work did influence James Joule, who, with the help of Rumford's near-namesake William Thomson, succeeded in getting the equivalence of heat and mechanical work accepted, but Rumford himself made no fundamental discoveries. He was more of an inventor, devising improved

  10. VHF Wind Profiling Radar Studies at Darwin, Australia

    2012-12-01

    A 54.1 MHz wind profiling radar was installed at Darwin, Australia in late 2005, to participate in the TWP-ICE campaign, and it has remained in this location. The primary purpose of the instrument was to measure the horizontal and vertical lower troposphere winds in the vertical column above the profiler. The profiler operates at 7.5 kW, and utilizes the Spaced Antenna Full Correlation Analysis (FCA) technique to measure winds, this achieving high temporal resolution. In addition to sampling the wind field, VHF profilers are capable of retrieving the rain drop size distribution (DSD), as radar returns are received from precipitation and clear-air with roughly equal magnitude. DSD retrievals then permit examination of the precipitation structure and spatial and temporal evolution in the vertical column above the profiler as rain bands pass over head. Understanding the evolution of the rain drop size distribution (DSD) in the descent from cloud to ground is important for quantitative precipitation estimation. The Darwin profiler has been used in multiple intercomparison studies. The FCA technique is well known to underestimate the wind magnitude by up to 10%, when compared to other measurement techniques, but agree well in direction. As the profiler is co-located with routine sonde launches, a large intercomparison data set exists, which can be used to investigate empirical corrections to the underestimation. Similarly, profiler vertical velocity estimates can be compared to Doppler Lidar measurements, and the relative strengths of both instruments examined. The profiler can also be used in rainfall studies. During TWP-ICE, when rainfall events passed over the profiler the DSD was retrieved. Each rain event was then separated into stratiform, convective and transitional regions. The integral rainfall parameters were then averaged through each region, and examined for evidence of a dominant microphysical process. For example, evaporation is detected through an

    2009-07-01

    This paper discussed the challenges that oil spill responder face when dealing with an incident on docks, piers and other marine structures. In September 2008, Bunker C fuel oil was spilled from the M/T King Darwin during the offloading operation when a pipe flange broke on the deck of the tanker. An estimated 64 tonnes of fuel was spilled in the West Wharf in Dalhousie, New Brunswick. The incident provided an opportunity to develop a response process designed for under-dock structures. The response process involved the following 3 phases: (1) survey and documentation, (2) assessment and characterization, and (3) under-dock treatment plan, development and implementation. Containment booms were deployed around the vessel and dock to control the movement of oil. Oil was also contained on the surface decking of the dock. Most of the oil was contained to the immediate area of the dock. Only a small amount of oil escaped outside the containment boom. The methodology used in this incident proved to be effective and has broader application for future spills. The development of a Dock Oiling Cleanup Assessment Technique (DOCAT) that is complimentary to the established Shoreline Cleanup Assessment Technique (SCAT) process was recommended. 2 refs., 2 tabs., 6 figs.

  12. Postcopulatory sexual selection: Darwin's omission and its consequences.

    2009-06-16

    In one of his few major oversights, Darwin failed to appreciate that male-male competition and sexual selection can continue even after copulation has begun. The postcopulatory equivalents of both direct male-male battles (sperm competition) and female choice (cryptic female choice) occur within the female's body. Recognition of this hidden, but intense, sexual competition provides new insights into a variety of fields. These include the hyperdiverse and paradoxically elaborate morphology of both sperm and male genitalia, the equally puzzling and elaborate morphology of nongenitalic male structures that are specialized to grasp and stimulate females, powerful manipulative effects of substances in male semen on female reproductive physiology, paradoxical male courtship behavior that occurs after copulation has already begun, variability in parental investments, and the puzzlingly complex and diverse interactions between sperm and female products that surround animal eggs and between male gametophytes and female tissues in flowering plants. Many bizarre traits are involved, including male genitalia that are designed to explode or fall apart during copulation leaving behind parts within the female, male genitalia that "sing" during copulation, potent seminal products that invade the female's body cavity and her nervous system to influence her behavior, and a virtual Kama Sutra of courtship behavior performed after rather than before genital coupling, including male-female dialogues during copulation.

  13. Universal Darwinism As a Process of Bayesian Inference.

    Science.gov (United States)

    Campbell, John O

    2016-01-01

    Many of the mathematical frameworks describing natural selection are equivalent to Bayes' Theorem, also known as Bayesian updating. By definition, a process of Bayesian Inference is one which involves a Bayesian update, so we may conclude that these frameworks describe natural selection as a process of Bayesian inference. Thus, natural selection serves as a counter example to a widely-held interpretation that restricts Bayesian Inference to human mental processes (including the endeavors of statisticians). As Bayesian inference can always be cast in terms of (variational) free energy minimization, natural selection can be viewed as comprising two components: a generative model of an "experiment" in the external world environment, and the results of that "experiment" or the "surprise" entailed by predicted and actual outcomes of the "experiment." Minimization of free energy implies that the implicit measure of "surprise" experienced serves to update the generative model in a Bayesian manner. This description closely accords with the mechanisms of generalized Darwinian process proposed both by Dawkins, in terms of replicators and vehicles, and Campbell, in terms of inferential systems. Bayesian inference is an algorithm for the accumulation of evidence-based knowledge. This algorithm is now seen to operate over a wide range of evolutionary processes, including natural selection, the evolution of mental models and cultural evolutionary processes, notably including science itself. The variational principle of free energy minimization may thus serve as a unifying mathematical framework for universal Darwinism, the study of evolutionary processes operating throughout nature.

    2007-07-01

    For 8 years I have been pursuing in print an ambitious and at times highly technical programme of work, the 'Formal Darwinism Project', whose essence is to underpin and formalize the fitness optimization ideas used by behavioural ecologists, using a new kind of argument linking the mathematics of motion and the mathematics of optimization. The value of the project is to give stronger support to current practices, and at the same time sharpening theoretical ideas and suggesting principled resolutions of some untidy areas, for example, how to define fitness. The aim is also to unify existing free-standing theoretical structures, such as inclusive fitness theory, Evolutionary Stable Strategy (ESS) theory and bet-hedging theory. The 40-year-old misunderstanding over the meaning of fitness optimization between mathematicians and biologists is explained. Most of the elements required for a general theory have now been implemented, but not together in the same framework, and 'general time' remains to be developed and integrated with the other elements to produce a final unified theory of neo-Darwinian natural selection.

  15. Is Beak Morphology in Darwin's Finches Tuned to Loading Demands?

    Directory of Open Access Journals (Sweden)

    Joris Soons

    Full Text Available One of nature's premier illustrations of adaptive evolution concerns the tight correspondence in birds between beak morphology and feeding behavior. In seed-crushing birds, beaks have been suggested to evolve at least in part to avoid fracture. Yet, we know little about mechanical relationships between beak shape, stress dissipation, and fracture avoidance. This study tests these relationships for Darwin's finches, a clade of birds renowned for their diversity in beak form and function. We obtained anatomical data from micro-CT scans and dissections, which in turn informed the construction of finite element models of the bony beak and rhamphotheca. Our models offer two new insights. First, engineering safety factors are found to range between 1 and 2.5 under natural loading conditions, with the lowest safety factors being observed in species with the highest bite forces. Second, size-scaled finite element (FE models reveal a correspondence between inferred beak loading profiles and observed feeding strategies (e.g. edge-crushing versus tip-biting, with safety factors decreasing for base-crushers biting at the beak tip. Additionally, we identify significant correlations between safety factors, keratin thickness at bite locations, and beak aspect ratio (depth versus length. These lines of evidence together suggest that beak shape indeed evolves to resist feeding forces.

    2009-09-01

    This essay offers a chronological survey of the range of songs and musical productions inspired by Darwin and his theory since they entered the public sphere some 150 years ago.It draws on an unusual set of historical materials, including illustrated sheet music, lyrics and librettos, wax cylinder recordings, vinyl records, and video recordings located in digital and sound archives and on the Internet. It also offers a characterization of the varied genres and a literary analysis of the forms as a way of understanding the diverse audiences engaging, and indeed "entertaining," Darwin and the implications of his theory. It argues that the engagement with Darwin and his celebrated theory is far more creative than has been appreciated and recommends that historians of science further explore Darwin and his theory as embodied ina fuller range of cultural expressions. This will lead to an understanding of Darwin's "iconic"status that draws on a fuller range of human sensory experience and that also enables us to appreciate his--and his theory's-enduring power to engage the human imagination.

    Charles Peirce (1839-1914) was one of the most important logicians of the nineteenth century. This thesis traces the development of his algebraic logic from his early papers, with especial attention paid to the mathematical aspects. There are three main sources to consider. 1) Benjamin Peirce (1809-1880), Charles's father and also a leading American mathematician of his day, was an inspiration. His memoir Linear Associative Algebra (1870) is summarised and for the first time the algebraic ...

    Ferry, A P

    1986-09-01

    Charles A. Tyrrell was a masseur who obtained his MD degree at age 57 in 1900. In addition to his private practice he was editor of several pseudomedical magazines. He also owned two proprietary ventures that he conducted on a mail order basis. One of these involved production and sale of the The Ideal Sight Restorer, a U-shaped device consisting of a rubber bulb at the base, from which on both sides arose an arm of rubber tubing capped by an ivory eye piece. The eye cups were applied to the closed eyelids and the intermittent suction produced by squeezing the rubber bulb was claimed to provide a form of ocular massage capable of curing serious eye diseases (eg. cataract and glaucoma), as well as doing away with the need for spectacles. Although his fraudulent activities and deceptive advertising practices were described on several occasions in the Journal of the American Medical Association, Dr. Tyrrell persisted in his enterprises until he died in 1918.

  19. On Cas A, Cassini, Comets and King Charles

    CERN Document Server

    Soria, Roberto; Ohtsuka, Yasuyo

    2013-01-01

    We re-examine the long-standing problem of the date of the Cassiopeia A supernova (SN), in view of recent claims that it might be the 1630 "noon-star" seen at the birth of King Charles II. We do not support this identification, based on the expected brightness of a Type-IIb SN (too faint to be seen in daylight), the extrapolated motion of the ejecta (inconsistent with a date earlier than 1650), the lack of any scientific follow-up observations, the lack of any mention of it in Asian archives. The origin of the 1630 noon-star event (if real) remains a mystery; there was a bright comet in 1630 June but no evidence to determine whether or not it was visible in daylight. Instead, we present French reports about a 4th-magnitude star discovered by Cassini in Cassiopeia in or shortly before 1671, which was not seen before or since. The brightness is consistent with what we expect for the Cas A SN; the date is consistent with the extrapolated motion of the ejecta. We argue that this source could be the long-sought SN...

    2013-09-01

    Full Text Available Charles Everett Koop was a great Surgeon General, probably the most influential in the history of the United States of America. He never missed courage in his life and often he had used it to tackle professional and personal tough problems.In his public activity, he faced controversial health problems of American people as smoking, abortion and the first occurrence of the epidemic Acquired Immune Deficiency Syndrome (AIDS. Koop was a rigorous man. The lodestar that guided Koop in his work, as a public servant was to do the best for health of Americans. In his prestigious and difficult role, he faced the pressing problems of health of millions of people trying to avoid political influence. During his mandate of eight years, Koop increased the influence and authority of his role. His appearance and behaviour were unmistakable: Lincolnesque beard and uniform, conduct hard and pure, exclusively oriented to the health of citizens, over the personal conveniences, political pressure and lobbying. An exemplary man, who for his passion for medicine and his sincere interest in promoting public health, was affectionately considered the "Family Doctor of America".

  1. 'The adventure': Charles-Ferdinand Ramuz's extraordinary stroke diary.

    Science.gov (United States)

    Bogousslavsky, J

    2010-01-01

    The famous Swiss writer Charles-Ferdinand Ramuz suffered a stroke at 65 years, which he called 'the adventure' or 'the accident'. He developed language disturbances suggesting crossed aphasia in a right hander with left hemiparesis. This uncommon pattern allowed him to continue to write his diary and to report his disturbances, with a unique depth and precision, especially for cognitive-emotional changes. Language and motor dysfunction recovered within a few weeks, but Ramuz complained of persisting emotional flattening alternating with irritability, fatigue, depression, anxiety, and concentration difficulty, which gave him the feeling to have become another person and to be inhabited by a stranger, whom he compared with devils. Ramuz fought several months to resume his literary activity, having the impression to have lost inspiration and creativity. However, the novels he wrote less than 6 months after stroke show no stylistic changes and have been found to be of the same quality as his previous production. Ramuz even 'used' his stroke experience in his work, in particular in a novel depicting an old man who has a stroke and dies of it. Ramuz's diary, with his own daily description of stroke features and consequences during acute and recovery phases, is a unique document in a writer of his importance, and provides invaluable information on subjective emotional and cognitive experience of stroke.

  2. Darwin's manufactory hypothesis is confirmed and predicts the extinction risk of extant birds.

    Directory of Open Access Journals (Sweden)

    David G Haskell

    Full Text Available In the Origin of Species Darwin hypothesized that the "manufactory" of species operates at different rates in different lineages and that the richness of taxonomic units is autocorrelated across levels of the taxonomic hierarchy. We confirm the manufactory hypothesis using a database of all the world's extant avian subspecies, species and genera. The hypothesis is confirmed both in correlations across all genera and in paired comparisons controlling for phylogeny. We also find that the modern risk of extinction, as measured by "Red List" classifications, differs across the different categories of genera identified by Darwin. Specifically, species in "manufactory" genera are less likely to be threatened, endangered or recently extinct than are "weak manufactory" genera. Therefore, although Darwin used his hypothesis to investigate past evolutionary processes, we find that the hypothesis also foreshadows future changes to the evolutionary tree.

  3. Claiming Darwin: Stephen Jay Gould in contests over evolutionary orthodoxy and public perception, 1977-2002.

    Science.gov (United States)

    Sheldon, Myrna Perez

    2014-03-01

    This article analyzes the impact of the resurgence of American creationism in the early 1980s on debates within post-synthesis evolutionary biology. During this period, many evolutionists criticized Harvard biologist Stephen Jay Gould for publicizing his revisions to traditional Darwinian theory and opening evolution to criticism by creationists. Gould's theory of punctuated equilibrium was a significant source of contention in these disputes. Both he and his critics, including Richard Dawkins, claimed to be carrying the mantle of Darwinian evolution. By the end of the 1990s, the debate over which evolutionary thinkers were the rightful heirs to Darwin's evolutionary theory was also a conversation over whether Darwinism could be defended against creationists in the broader cultural context. Gould and others' claims to Darwin shaped the contours of a political, religious and scientific controversy. PMID:24457049

  4. A multi-dimensional, energy- and charge-conserving, nonlinearly implicit, electromagnetic Vlasov-Darwin particle-in-cell algorithm

    CERN Document Server

    Chen, Guangye

    2015-01-01

    For decades, the Vlasov-Darwin model has been recognized to be attractive for particle-in-cell (PIC) kinetic plasma simulations in non-radiative electromagnetic regimes, to avoid radiative noise issues and gain computational efficiency. However, the Darwin model results in an elliptic set of field equations that renders conventional explicit time integration unconditionally unstable. Here, we explore a fully implicit PIC algorithm for the Vlasov-Darwin model in multiple dimensions, which overcomes many difficulties of traditional semi-implicit Darwin PIC algorithms. The finite-difference scheme for Darwin field equations and particle equations of motion is space-time-centered, employing particle sub-cycling and orbit-averaging. The algorithm conserves total energy, local charge, canonical-momentum in the ignorable direction, and preserves the Coulomb gauge exactly. An asymptotically well-posed fluid preconditioner allows efficient use of large time steps and cell sizes, which are determined by accuracy consid...

    Graphical abstract: The two-electron Darwin term is computed analytically at the MP2-F12 level of theory using density fitted integrals. Highlights: Black-Right-Pointing-Pointer Two-electron Darwin term computed analytically at the MP2-F12 level. Black-Right-Pointing-Pointer Darwin two-electron integrals computed using density fitting techniques. Black-Right-Pointing-Pointer Two-electron Darwin term dominated by singlet pair contributions. Black-Right-Pointing-Pointer Much improved basis set convergence is achieved with F12 methods. Black-Right-Pointing-Pointer Interference correction works well for the two-electron Darwin term. - Abstract: This article is concerned with the calculation of the two-electron Darwin term (D2). At the level of explicitly correlated second-order perturbation theory (MP2-F12), the D2 term is obtained as an analytic energy derivative; at the level of explicitly correlated coupled-cluster theory, it is obtained from finite differences. To avoid the calculation of four-center integrals, a density-fitting approximation is applied to the D2 two-electron integrals without loss of accuracy, even though the absolute value of the D2 term is typically about 0.1 mE{sub h}. Explicitly correlated methods provide a qualitatively correct description of the short-range region around the Coulomb hole, even for small orbital basis sets. Therefore, explicitly correlated wave functions remedy the otherwise extremely slow convergence of the D2 contribution with respect to the basis-set size, yielding more accurate results than those obtained by two-point basis-set extrapolation. Moreover, we show that the interference correction of Petersson's complete-basis-set model chemistry can be used to compute a D2 basis-set correction at the MP2-F12 level to improve standard coupled-cluster singles-and-doubles results.

  8. The life and significance of Charles Lucas (1713-1771).

    Science.gov (United States)

    Kelly, J

    2015-09-01

    Charles Lucas (1713-1771) was one of the most controversial popular politicians to stride the Irish political stage in the eighteenth century. Though the descendant of a beneficiary of the Cromwellian plantation, Lucas's personal inheritance was small, and he was apprenticed in his teens to an apothecary in Dublin. Lucas prospered in that capacity, both as an advocate of higher standards within the profession, and as a representative on the lower house (the common council) of Dublin Corporation. Predisposed to challenge what he perceived as abuses by vested and established interests, Lucas made a name for himself as an outspoken critic of the oligarchical pretensions of the lord mayor and aldermen, which comprised the upper chamber of the Corporation. His successes were few, but he was possessed of a fluent pen, and a precocious awareness that he could best communicate with his natural audience through the use of print. As a result, he became the darling of an emerging popular political interest, which shared his vision of a reformed Protestant constitution. Encouraged by this positive response, Lucas offered himself to the electorate of Dublin in 1749, but though he campaigned vigorously, and polled well, he was not elected. More consequently for Lucas personally, his extension of his critical gaze from the municipality to the larger canvas of national and Anglo-Irish politics elicited the hostile notice of the most powerful figures in the land, which prompted him to flee the country to avoid imprisonment. Lucas was not inactive during his eleven-year 'exile', but these were comparatively quiet years by comparison with his final decade when, following his return to Ireland in 1761, he acquired a national profile as MP for Dublin City, a vigorous advocate, and a tireless proponent of Patriot policies.

  10. Orogenesis at the southern tip of the Americas: the structural evolution of the Cordillera Darwin metamorphic complex, southernmost Chile

    Science.gov (United States)

    Cunningham, W. Dickson

    1995-04-01

    New, detailed lithologic and structural data are presented from three separately mapped areas along the southern boundary of the Cordillera Darwin metamorphic complex of southernmost Chile. Cordillera Darwin is a unique uplift because it exposes the highest grade rocks in the Andes south of Peru and averages 1 km higher in elevation than adjacent areas. The structural data indicate that Cordillera Darwin experienced mid-Late Cretaceous trans-pressional deformation with a partitioned strike-slip component localized along the Beagle Channel that forms the southern boundary to the range. Foliation, lineation and fold axis trends indicate NE-SW-directed contraction and NW-SE strike-slip shearing (present directions) during progressive {D1}/{D2} Andean deformation. D2 deformation is marked by outcrop-to 10 km-scale south-southwest-vergent folds. Late Cretaceous-Tertiary brittle-ductile and brittle left-lateral strike-slip faults and shear zones crosscut all {D1}/{D2} structures. Although limited structural evidence for extensional tectonics was documented in this study, apparent normal offsets across both arms of the Beagle Channel and previously documented field evidence for extension from other areas in Cordillera Darwin suggest that transtensional displacements also may have occurred in southern Cordillera Darwin during the Late Cretaceous-Early Tertiary. Cordillera Darwin's position within the evolving Patagonian Orocline adjacent to an evolving Mesozoic-Cenozoic left-lateral transform boundary between the South American and Antarctic plates, and later the South American and Scotia plates, necessitates consideration of the possible effects of regional counterclockwise rotation on development of structures. Regional counterclockwise rotation of Cordillera Darwin may have controlled the temporal and spatial transition of deformational regimes within Cordillera Darwin. Exhumation of the metamorphic core of Cordillera Darwin during the Late Cretaceous-Early Tertiary is

  11. BOOK REVIEW: Jean-Charles Houzeau et son temps

    Science.gov (United States)

    Sterken, C.; Verhas, P.

    2002-12-01

    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

  15. Making a Theist out of Darwin: Asa Gray's Post-Darwinian Natural Theology

    Science.gov (United States)

    Russell Hunter, T.

    2012-07-01

    In March of 1860 the eminent Harvard Botanist and orthodox Christian Asa Gray began promoting the Origin of Species in hopes of securing a fair examination of Darwin's evolutionary theory among theistic naturalists. To this end, Gray sought to demonstrate that Darwin had not written atheistically and that his theory of evolution by natural selection had not presented any new scientific or theological difficulties for traditional Christian belief. From his personal correspondence with the author of the Origin, Gray well knew that Darwin did not affirm God's "particular" design of nature but conceded to the possibility that evolution proceeded according to "designed laws." From this concession, Gray attempted to develop a post-Darwinian natural theology which encouraged theistic naturalists to view God's design of nature through the evolutionary process in a manner similar to the way in which they viewed God's Providential interaction with human history. Indeed, securing a fair reading of the Origin was not Gray's sole aim as a promoter of Darwinian ideas. In Darwin's theory of natural selection, Gray believed he had discovered the means by which a more robust natural theological conception of the living and evolving natural world could be developed. In this paper I outline Gray's efforts to produce and popularize a theistic interpretation of Darwinian theory in order to correct various misconceptions concerning Gray's natural theological views and their role in the Darwinian Revolution.

  16. DARWIN. An evolution code system for a large range of applications

    International Nuclear Information System (INIS)

    The aim of this article is to present the main capabilities of an evolution code system, DARWIN, developed at CEA (France). It is devoted to radioactivity studies in various application fields such as nuclear fuel cycle, dismantling, thermonuclear fusion, accelerator driven system, medecine etc. All types of nuclides are dealt with: actinides, fission products, activation products, spallation products. Physical quantities calculated by the code are isotope concentration, isotope mass, activity, radiotoxicity, gamma spectra, beta spectra, alpha spectra, neutron production by spontaneous fission and (α, n) reaction, residual heating, for any cooling times until geological times. Both analytical and numerical schemes are developed in the PEPIN2 depletion module of DARWIN to solve the generalized coupled differential depletion equations. The depletion module PEPIN2 is automatically linked to international evaluations (JEF2, ENDF/B6, EAF97...) both for decay data and cross-sections, and to some transport codes such as TRIPOLI, APOLLO2 and ERANOS. These transport codes provide neutronic data as self-shielded cross-sections and neutron fluxes. DARWIN includes a generator of radioisotope chain built automatically from decay modes and nuclear reaction types specified in the evaluation libraries. A 'search engine' allows to determine all formation ways of a considered isotope. Several examples are given for illustrating capabilities of DARWIN in different field applications. Some comparisons with other codes such as ORIGEN, FISPIN and FISPACT are also presented. (author)

    The discovery of extrasolar planets is one of the greatest achievements of modern astronomy. The detection of planets that vary widely in mass demonstrates that extrasolar planets of low mass exist. In this paper, we describe a mission, called Darwin, whose primary goal is the search for, and characterization of, terrestrial extrasolar planets and the search for life. Accomplishing the mission objectives will require collaborative science across disciplines, including astrophysics, planetary sciences, chemistry, and microbiology. Darwin is designed to detect rocky planets similar to Earth and perform spectroscopic analysis at mid-infrared wavelengths (6-20 mum), where an advantageous contrast ratio between star and planet occurs. The baseline mission is projected to last 5 years and consists of approximately 200 individual target stars. Among these, 25-50 planetary systems can be studied spectroscopically, which will include the search for gases such as CO(2), H(2)O, CH(4), and O(3). Many of the key technologies required for the construction of Darwin have already been demonstrated, and the remainder are estimated to be mature in the near future. Darwin is a mission that will ignite intense interest in both the research community and the wider public. PMID:19203238

  1. Experimental validation of the DARWIN2.3 package for fuel cycle applications

    International Nuclear Information System (INIS)

    The DARWIN package, developed by the CEA and its French partners (AREVA and EDF), provides the parameters required for fuel cycle applications: fuel inventory; decay heat; activity; neutron, gamma, alpha, and beta sources and spectra; and radiotoxicity. This paper presents the DARWIN2.3 experimental validation for fuel inventory and decay heat calculations on pressurized water reactors (PWRs). To validate this code system for spent fuel inventory, a large program has been undertaken, based on spent fuel chemical assays. This paper deals with the experimental validation of DARWIN2.3 for PWR uranium oxide and mixed oxide (MOX) fuel inventory calculation, focused on the isotopes involved in burnup credit applications and decay heat computations. The calculation to experiment ratio [(C E)/1] discrepancies are calculated with the latest European evaluation file JEFF-3.1.1 associated with the Santamarina-Hfaiedh energy mesh. An overview of the tendencies is obtained on a complete range of burnup from 10 to 85 GWd/tonne (10 to 60 GWd/tonne for MOX fuel). The experimental validation of the DARWIN2.3 package for decay heat calculation is performed using calorimetric measurements carried out at the Swedish interim spent fuel storage facility, Clab, for PWR assemblies, covering large burnup (20 to 50 GWd/tonne) and cooling time (10 to 30 year) ranges.

  3. Friedrich Albert Lange on neo-Kantianism, socialist Darwinism, and a psychology without a soul.

    Friedrich Albert Lange was a German philosopher, political theorist, educator, and psychologist who outlined an objective psychology in the 1860s. This article shows how some of the most important worldviews of the nineteenth century (Kantianism, Marxism, and Darwinism) were combined creatively in his thought system. He was crucial in the development of neo-Kantianism and incorporated psycho-physiological research on sensation and perception in order to defend Kant's epistemological idealism. Based on a critique of phrenology and philosophical psychology of his time, Lange developed a program of a psychology without a soul. He suggested that only those phenomena that can be observed and controlled should be studied, that psychology should focus on actions and speech, and that for each psychological event the corresponding physical or physiological processes should be identified. Lange opposed introspection and subjective accounts and promoted experiments and statistics. He also promoted Darwinism for psychology while developing a socialist progressive-democratic reading of Darwin in his social theory. The implications of socialist Darwinism on Lange's conceptualization of race are discussed and his prominence in nineteenth century philosophy and psychology is summarized. PMID:12115788

    A simple reminder of the fact that we do not always control life's outcomes reduced people's belief in Darwin's Theory of Evolution. This control-threat resulted in a relative preference for theories of life that thwart randomness, either by stressing the role of a controlling God (Intelligent Desig

  6. From Buenos Aires to Santa Fe: Darwin's observations and modern knowledge

    Full Text Available During his historical voyage around the world, Darwin raided deeply in the South American interior, travelling over 600 kilometers from Buenos Aires to the north along the Río Paraná. During that journey, he crossed a vast plain characterized by aeolian sediments, something unfamiliar to a European naturalist. However, Darwin's acute observation powers and precise descriptions are noteworthy. After more than 170 years since his visit, modern geological knowledge identifies several sectors in the Buenos Aires-Santa Fe region. One of them (the Tertiary at La Bajada he described admirably and others such as the Paraná flood plain were brilliantly abstracted in only two sentences. In short, Darwin traversed a first sector (Buenos Aires-Rosario characterized by aeolian and paludal Early Pleistocene sediments. From Rosario to Santa Fe the plain is formed by Late Pleistocene aeolian and fluvial units. At La Bajada (presently Paraná city lies exposed the marine Miocene and in SW Entre Ríos is a reconstructed loess-paleosol sequence generated at the Early/Middle Pleistocene transition. The Paraná flood plain and the littoral complex at the mouth (practically not observed by Darwin underwent rather complex Holocene episodes.

    We comment on a recent paper by Rama Singh, who concludes that Mendel deserved to be called the father of genetics, and Darwin would not have understood the significance of Mendel's paper had he read it. We argue that Darwin should have been regarded as the father of genetics not only because he was the first to formulate a unifying theory of heredity, variation, and development -- Pangenesis, but also because he clearly described almost all genetical phenomena of fundamental importance, including what he called "prepotency" and what we now call "dominance" or "Mendelian inheritance". The word "gene" evolved from Darwin's imagined "gemmules", instead of Mendel's so-called "factors". PMID:26651239

    Full Text Available Christian Norberg- Schulz explained his ideas about the phenomenology of architecture, indebted to Martin Heidegger’s opinionsand believed that one of the main strategies for identification of the place is creating meaningful environments. Schulz can be considered as one of theorists who created new ideas in architecture after Gideon and believed that considering to other scientific fields is necessary to achieve the true nature of architecture. In fact the phenomenological approach can be understood as an interdisciplinary species that explain about existence and cognition in other fields like designing different spaces. Accordingly emphasizing on interdisciplinary trends and studies can help to identify and understand the multiple issues and by studying the different approaches, the scientific expansion of the problem’s aspects will be possible. This article with an Interdisciplinary and phenomenological point of view and due to the main ideas of Norberg- Schulz, analyses the concept of place and space and also the importance of concerning about children’s spaces. So at first a brief knowledge about the book of Norberg-Schulz in phenomenological approach will be achieved and by studying the opinions of other theorists, some results about the importance of considering the concept of genius loci in architectural spaces will be achieved. In this document, by using the descriptive- analytical method and by means of data collection, including studies, library and documentation, the relating concepts and strategies of improving the quality of children’s spaces, is analyzed. According to this article, It could be said that meanings, culture and history of a place, include identifying factors that cause creating memories and a sense of belonging to the place for individuals and thus the formation of their personality in childhood. So one of the main tasks of modern architects is creating a sense of space in children’s spaces and reminding

  12. Darwin, malthus, süssmilch, and euler: the ultimate origin of the motivation for the theory of natural selection.

    It is fairly well known that Darwin was inspired to formulate his theory of natural selection by reading Thomas Malthus's Essay on the Principle of Population. In fact, by reading Darwin's notebooks, we can even locate one particular sentence which started Darwin thinking about population and selection. What has not been done before is to explain exactly where this sentence - essentially Malthus's ideas about geometric population growth - came from. In this essay we show that eighteenth century mathematician Leonhard Euler is responsible for this sentence, and in fact forms the beginning of the logical chain which leads to the creation of the theory of natural selection. We shall examine the fascinating path taken by a mathematical calculation, the many different lenses through which it was viewed, and the path through which it eventually influenced Darwin.
