Good Natured: The Origins of Right and Wrong in Humans and Other Animals

To observe a dog's guilty look, to witness a gorilla's self-sacrifice for a wounded mate, to watch an elephant herd's communal effort on behalf of a stranded calf - to catch animals in certain acts is to wonder what moves them. Might there be a code of ethics in the animal kingdom? Must an animal be human to be humane? In this book, a scientist takes on those who have declared ethics uniquely human. Making a case for a morality grounded in biology, he shows that ethical behaviour, in humans and animals alike, is as much a matter of evolution as any other trait.
