Today's global economy and communications link all contemporary people, directly or indirectly, in the modern world system. People must now cope with forces generated by progressively larger systems-the region, the nation, and the world. For anthropologists studying contemporary forms of adaptation, why might this be a challenge?
A. A more dynamic world system, with greater and faster movements of people across space, speeds up the process of evolution, making the study of genetic adaptations more difficult. B. According to Marcus and Fischer (1986), "The cultures of world peoples need to be constantly rediscovered as these people reinvent them in changing historical circumstances." C. Truly isolated indigenous communities, anthropology's traditional and ongoing study focus, are becoming harder to find. D. Since cultures are tied to place, people moving around and connecting across space means the end of culture, and thus the end of anthropology. E. Anthropological research tools do not work in this new modern world system, making their contributions less valuable.
