Based on extensive experimental data comparing great apes and human children, Michael Tomasello reconstructs how early humans gradually became an ultra-cooperative and, eventually, a moral species.“Tomasello is convincing, above all, because he has run many of the relevant studies (on chimps, bonobos and children) himself. He concludes by emphasizing the powerful influence of broad cultural groups on modern humans… Tomasello also makes an endearing guide, appearing happily amazed that morality exists at all.”—Michael Bond, New Scientist“Most evolutionary theories picture humans as amoral ‘monads’ motivated by self-interest. Tomasello presents an innovative and well-researched, hypothesized natural history of two key evolutionary steps leading to full-blown morality.”—S. A. Mason, Choice
