Evolutionary anthropology has focused on the origins of war, or rather ethnocentricity, because it epitomizes the problem of group selection, and because war may itself have been the main agent of group selection. The neo-Darwinian synthesis in biology has explained how ethnocentricity might evolve by group selection, and the distinction between evoked culture and adopted culture, suggested by the emerging synthesis in evolutionary psychology, has explained how it might be transmitted. Ethnocentric mechanisms could have evolved by genetic selection in ancestral hominids, or through the interaction of genetic and cultural selection in modern humans, or both. The existence of similar behaviors in chimpanzees and the parallel development of early human societies around the globe are arguments for such inherited mechanisms. There may have been some adaptive breakthroughs in purely cultural evolution, but this process does not seem likely to produce long-term Darwinian adaptations because of the prolificity of cultural traits. Warfare may once have been a major agent of group selection, but the rates of extinction among human groups are so slow as to render this improbable since the rise of state-level societies, whose warfare tends to become a cyclical balance-of-power situation. Perhaps the most serious implication of current evolutionary thought is that the individualistic model of culture common in the social sciences and humanities is outmoded, and should be replaced by a new model that recognizes the organismic nature of human societies. 相似文献

Age-related memory loss was a marginal issue in medical discussions during early modern times and until well into the second half of the 17th century. There are many possible explanations: the lack of similar traditions in antiquity and in the Middle Ages, insufficient physiological and morphological knowledge of the brain, and the underlying conflict between idealistic and materialistic perspectives on the functions of the soul and the conditions of these in old age. After these boundaries had been pushed back by the influence of Cartesianism and Iatromechanism, the problem of age-related memory loss was increasingly regarded as a physical illness and began to receive more attention. This trend first occurred in medicine, before spreading to the literary world, where the novel "Gulliver's Travels" is one clear and famous example. 相似文献

The Swedish-Finnish Nobel laureate Ragnar Granit, born 100 years ago, is commemorated in a brief article by one of his former PhD students and collaborators. After a short account of Granit's life and scientific career, special attention is given to Granit's role as a teacher in research training and his published thoughts on this matter, partly reflecting Granit's own experience as a "postdoc" in the laboratory of Sherrington (Oxford). The article includes personal recollections of how it was to work together with Granit in his laboratory. 相似文献

Crossed brainstem syndromes consist of ipsilateral impairment of cranial nerves III-XII and contralateral impairment of the pyramidal and sensory tracts. Gasperini's syndrome, described in 1912 by the Italian internist Ubaldo Gasperini, is one of them. It results from a lesion of the caudal pontine tegmentum and is most frequently defined as ipsilateral impairment of cranial nerves V, VI, VII, and VIII and contralateral sensory loss. Since no autopsy was performed to confirm Gasperini's clinical observations, we analyzed all elements of his syndrome from a current perspective as well as in the light of the anatomical knowledge available to him. This resulted in a historical survey of the development of neuroanatomy over the last 300 years. 相似文献
