highly variable beliefs and practices. Thus, "culture" not only transcends the opposition between nature and nurture; it transcends and absorbs the peculiarly European distinction between politics, religion, kinship, and the economy as autonomous domains. Anthropology thus transcends the divisions between the natural sciences, social sciences, and humanities to explore the biological, linguistic, material, and symbolic dimensions of humankind in all forms. National anthropological traditions As academic disciplines began to differentiate over the course of the nineteenth century, anthropology grew increasingly distinct from the biological approach of natural history, on the one hand, and from purely historical or literary fields such as Classics, on the other. A common criticism was that many social sciences (such as economists, sociologists, and psychologists) in Western countries focused disproportionately on Western subjects, while anthropology focused disproportionately on the "other". Britain Museums such as the British Museum weren't the only site of anthropological studies: with the New Imperialism period, starting in the 1870s, zoos became unattended "laboratories", especially the so-called "ethnological exhibitions" or "Negro villages". Thus, "savages" from the colonies were displayed, often nudes, in cages, in what has been called "human zoos". For example, in 1906, Congolese pygmy Ota Benga was put by anthropologist Madison Grant in a cage in the Bronx Zoo, labelled "the missing link" between an orangutan and the "white race"—Grant, a renowned eugenicist, was also the author of The Passing of the Great Race (1916). Such exhibitions were attempts to illustrate and prove in the same movement the validity of scientific racism, which first formulation may be found in Arthur de Gobineau's An Essay on the Inequality of Human Races (1853–55). In 1931, the Colonial Exhibition in Paris still displayed Kanaks from New Caledonia in the "indigenous village"; it received 24 million visitors in six months, thus demonstrating the popularity of such "human zoos". Anthropology grew increasingly distinct from natural history and by the end of the nineteenth century the discipline began to crystallize into its modern form—by 1935, for example, it was possible for T.K. Penniman to write a history of the discipline entitled A Hundred Years of Anthropology. At the time, the field was dominated by 'the comparative method'. It was assumed that all societies passed through a single evolutionary process from the most primitive to most advanced. Non-European societies were thus seen as evolutionary 'living fossils' that could be studied in order to understand the European past. Scholars
