In The Moral Animal, the popular science journalist Robert Wright — author of Three Scientists and Their Gods: Looking for Meaning in an Age of Information and Non-Zero: The Logic of Human Destiny — turns his attention to the new science of evolutionary psychology. Summarizing and synthesizing a wealth of state-of-the art scientific information, Wright provocatively argues that human moral behavior was — and is — largely shaped by our adaptation to the ancestral environment. His points are cheekily exemplified with episodes from the life of Charles Darwin himself. The reviewer for The Economist writes, "This clever and stimulating book is destined to become a classic."
