Fifty years ago, a troop of Japanese macaques was observed washing sandy sweet potatoes in a stream, sending ripples through the fields of ethology, comparative psychology, and cultural anthropology. The issue of animal culture has been hotly debated ever since. Now Kevin Laland and Bennett Galef have gathered key voices in the often rancorous debate to summarize the views along the continuum from "Culture? Of course!" to "Culture? Of course not!" The result is essential reading for anyone interested in the validity of animal culture, and what it might say about our own.

Short of inventing a time machine, we will never see our extinct forebears in action and be able to determine directly how human behaviour and culture has developed. However, we can learn from our closest living relatives, the African great apes. The Cultured Chimpanzee explores the astonishing variation in chimpanzee behavior across their range, which cannot be explained by individual learning, genetic or environmental influences. It promotes the view that this rich diversity in social life and material culture reflects social learning of traditions, and more closely resembles cultural variety in humans than the simpler behavior of other animal species. This stimulating book shows that the field of cultural primatology may therefore help us to reconstruct the cultural evolution of Homo sapiens from earlier forms, and that it is essential for anthropologists, archaeologists and zoologists to work together to develop a stronger understanding of human and primate cultural evolution. ?? First book to provide a synthetic analysis of chimpanzee culture, covering both material and social culture ?? Models the origins and evolution of human culture using our closest living relatives, the chimpanzees ?? A significant and stimulating book which examines how anthropology, animal behavior and psychology must come together to truly understand the basis for human and animal culture

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 research on the subject. "Tree of Origin" gives us the latest news about bonobos, the "make love not war" apes who behave so dramatically unlike chimpanzees. We learn about the tool traditions and social customs that set each ape community apart. We see how DNA analysis is revolutionizing our understanding of paternity, intergroup migration, and reproductive success. And we confront intriguing discoveries about primate hunting behavior, politics, cognition, diet, and the evolution of language and intelligence that challenge claims of human uniqueness in new and subtle ways.

"Tree of Origin" provides the clearest glimpse yet of the apelike ancestor who left the forest and began the long journey toward modern humanity.

Do chimpanzees have something akin to culture? Bringing together studies of behavioral variation within and among chimpanzees and bonobos --the sibling species of the genus "Pan"--this book provides the basis for answering this question. In "Chimpanzee Cultures," the world's leading authorities on chimpanzees and bonobos chronicle the animals' behaviors from one study site to the next, in both captive and wild groups, in laboratory and field settings.
