From Edge:

Thanks to Steven Pinker for initiating and facilitating this Edge Special Event with Napoleon Chagnon, the last of the great ethnographers.

INTRODUCTION By Richard Dawkins

Napoleon Chagnon is a Living World Treasure. Arguably our greatest anthropologist, he is brave on two fronts. As a field worker in the Amazon forest he has lived, intimately and under conditions of great privation, with The Fierce People at considerable physical danger to himself. But the wooden clubs and poison-tipped arrows of the Yanomamö were matched by the verbal clubs and toxic barbs of his anthropologist colleagues in the journal pages and conference halls of the United States. And it is not hard to guess which armamentarium was the more disagreeable to him.

Chagnon committed the unforgivable sin, cardinal heresy in the eyes of a certain kind of social scientist: he took Darwin seriously. Along with a few friends and colleagues, Chagnon studied the up-to-date literature on natural selection theory, and with brilliant success he applied the ideas of Fisher, Hamilton, Trivers and other heirs of Darwin to a human tribe which probably ran as close to the cutting edge of natural selection as any in the world. It is sobering to reflect on how unconventional a step this was: science bursting into the quasi-literary world of the anthropology in which the young Chagnon was trained. Still today, in many American departments of social science, for a young researcher to announce a serious interest in Darwin's dangerous idea—even an inclination towards scientific thinking at all—can come close to career suicide.
