Description:
Most evolutionary biologists agree that what makes humans unique among animals is our brainpower. But why--and how--did we evolve our oversized brains? Craig Stanford dusts off the old "Man the Hunter" theory, roundly criticized as replete with bad (and sexist) assumptions, and finds a thick, juicy, postmodern steak at the heart of it. He argues, "The origins of human intelligence are linked to the acquisition of meat, especially through the cognitive capacities necessary for the strategic sharing of meat with fellow group members." Stanford studied the great apes, especially chimpanzees, and came to the conclusion that among primates, meat is a valuable commodity both nutritionally and socially. Although many other foods are nutritionally desirable, meat is unique in its social desirability, and for males, it represents power: Underlying the nutritional aspect of getting meat, part of the social fabric of the community is revealed in the dominance displays, the tolerated theft, and the bartered meat for sexual access. The end of the hunt is often only the beginning of a whole other arena of social interaction. In Stanford's view, females play a crucial role in keeping groups together and cementing individual relationships. Meat plays an important role in the way males fit in to a society, and the ability of males to get meat readily may very well explain their societal dominance. These conclusions are not liable to be nearly so controversial as the way Stanford gathered his data--he drew broad parallels between chimps and modern hunter-gatherer societies. Stanford also admits that a lack of fossil evidence supporting his meat/brain link is problematic. The Hunting Apes is an interesting look at what is likely the worthwhile center of a discredited evolutionary theory. --Therese Littleton
