How did we become the linguistic, cultured, and hugely successful apes that we are? Our closest relatives--the other mentally complex and socially skilled primates--offer tantalizing clues. In Tree of Origin nine of the world's top primate experts read these clues and compose the most extensive picture to date of what the behavior of monkeys and apes can tell us about our own evolution as a species.

It has been nearly fifteen years since a single volume addressed the issue of human evolution from a primate perspective, and in that time we have witnessed explosive growth in...

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 he a code of ethics in the animal kingdom? Must an animal be human to he humane? In this provocative book, a renowned scientist takes on those who have declared ethics uniquely human Making a compelling case for a morality grounded in biology, he shows how ethical behavior is as much a matter of evolution as any other trait, in humans and animals...

Does biology condemn the human species to violence and war? Previous studies of animal behavior incline us to answer yes, but the message of this book is considerably more optimistic. Without denying our heritage of aggressive behavior, Frans de Waal describes powerful checks and balances in the makeup of our closest animal relatives, and in so doing he shows that to humans making peace is as natural as making war.

In this meticulously researched and absorbing account, we learn in detail how different types of simians cope with aggression, and how they make peace after fights....

It's no secret that humans and apes share a host of traits, from the tribal communities we form to our irrepressible curiosity. We have a common ancestor, scientists tell us, so it's natural that we act alike. But not all of these parallels are so appealing: the chimpanzee, for example, can be as vicious and manipulative as any human.

Yet there's more to our shared primate heritage than just our violent streak. In Our Inner Ape, Frans de Waal, one of the world's great primatologists and a renowned expert on social...

What separates your mind from an animal's? Maybe you think it's your ability to design tools, your sense of self, or your grasp of past and future--all traits that have helped us define ourselves as the planet's preeminent species. But in recent decades, these claims have eroded, or even been disproven outright, by a revolution in the study of animal cognition. Take the way octopuses use coconut shells as tools; elephants that classify humans by age, gender, and language; or Ayumu, the young male chimpanzee at Kyoto University whose flash memory puts that of humans to shame. Based on...
