Moral Evolution

Are men literally born to cheat? Does monogamy actually serve women's interests? These are among the questions that have made The Moral Animal one of the most provocative science books in recent years. Wright unveils the genetic strategies behind everything from our sexual preferences to our office politics - as well as their implications for our moral codes and public policies.

How did humans, a species of self-centered apes, come to care about others? Since Darwin, scientists have tried to answer this question using evolutionary theory. In The Kindness of Strangers, psychologist Michael E. McCullough shows why they have failed and offers a new explanation instead. From the moment nomadic humans first settled down until the aftermath of the Second World War, our species has confronted repeated crises that we could only survive by changing our behavior.

In this book, evolutionary psychologist Dennis Krebs explains how virtuous behaviors such as altruism, justice, honesty, loyalty, self-control, purity, and respect for authority, have evolved in humans and other species. He argues that the key to solving puzzles of morality—such as what it is, how we acquire moral traits, why we sometimes behave badly, and how we make moral decisions—lies in figuring out what adaptive functions moral traits served in early human environments and how they are influenced by social learning, culture, and strategic social interactions in the modern world.
