	Description:		On this week's episode of I, Dave speaks with Richard Wrangham, a British primatologist. Wrangham is co-director of the Kibale Chimpanzee Project, the long-term study of the Kanyawara chimpanzees in Kibale National Park, Uganda. He is known predominantly for his work in the ecology of primate social systems, the evolutionary history of human aggression (culminating in his book with Dale Peterson, Demonic Males: Apes and the Origins of Human Violence), and most recently his research in cooking (summarized in his book, Catching Fire: How Cooking Made Us Human) and self-domestication. Wrangham's latest work focuses on the role cooking has played in human evolution. He has argued that cooking food is obligatory for humans as a result of biological adaptations and that cooking, in particular the consumption of cooked tubers, might explain the increase in hominid brain sizes, smaller teeth and jaws, and decrease in sexual dimorphism that occurred roughly 1.8 million years ago.
