Richard Wrangham, a professor at Harvard University and author of Catching Fire, studies the role of cooking in human evolution. "Once you start thinking about the importance of cooking -- its supply of energy, its strange distribution compared to natural foods -- it's bound to have affected our evolution hugely, our behavior, our society, our cognition, all sorts of features about us," he says.
