问题 What is Chagnon’s view of the Yanomami? What is his explanation?

选项

答案Chagnon’s writings and films have promoted a long standing view of the Yanomami as exceptionally violent and war-loving. Chagnon provides a social biological explanation for the fierceness of the Yanomami. He explains that village raids and warfare are carried to obtain wives. Although the Yanomami prefer to marry within their village, there is a shortage of potential brides because the Yanomami practice the killing of female infants, which creates a scarcity of women. While the Yanomami prefer to marry within their own group, taking a wife from another group is preferable to remaining a bachelor. Men in other groups, however, are unwilling to give up their women; hence the necessity for raids. Chagnon also argues that, as successful warriors will be able to gain a wife or more than one wife, they often have more children than unsuccessful ones. Successful warriors, Chagnon suggests, carry a genetic advantage for fierceness, which they pass on to their sons, leading to a high growth rate of groups with violent males through genetic selection for fierceness. Male fierceness, in this view, is biologically determined.
