A Bold New Theory Proposes That Humans Tamed Themselves
A leading anthropologist suggests that protohumans became domesticated by killing off violent males.

In his new book, Wrangham grapples fully for the first time with the paradox of the title. Over the decades during which he has focused mostly on the dark side of human nature, evidence has steadily accumulated that humans, from early on in their development, are the most cooperative species in the primate world. Put apes and humans in situations that demand collaboration between two individuals to achieve a goal, as a variety of experimenters have done, and even young children perform better than apes. Meanwhile, classic work on chimps has been complemented by new studies of bonobos, our other close relative. No more removed from us genetically than chimps are, they are a radical contrast to them, often called the “make love, not war” species. Some of our nonhuman kin, such fieldwork has revealed, can live and evolve almost without violence.
Central to his argument is the idea that cooperative killing of incurably violent individuals played a central role in our self-domestication. Much as the Russian scientists eliminated the fierce fox pups from the breeding pool, our ancestors killed men who were guilty of repeated acts of violence. Certainly all-male raiding parties have operated in some groups of humans, seeking out and killing victims in neighboring villages (which recalls the patrolling chimps that Wrangham reported on earlier in his career). The twist in his current theory is that such ambushes are turned inward, to protect the group from one of its own: They serve as a form of capital punishment. Wrangham cites a number of examples of anthropologists witnessing a group of men collaborating to kill a violent man in their midst. |
