How our collective intelligence has helped us to evolve and prosper Humans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals? This book shows that the secret of our success lies not in our innate intelligence, but in our collective brains—on the ability of human groups to socially interconnect and learn from one another over generations. Drawing insights from lost European explorers, clever chimpanzees, mobile hunter-gatherers, neuroscientific findings, ancient bones, and the human genome, Joseph Henrich demonstrates how our collective brains have propelled our species' genetic evolution and shaped our biology. Our early capacities for learning from others produced many cultural innovations, such as fire, cooking, water containers, plant knowledge, and projectile weapons, which in turn drove the expansion of our brains and altered our physiology, anatomy, and psychology in crucial ways. Later on, some collective brains generated and recombined powerful concepts, such as the lever, wheel, screw, and writing, while also creating the institutions that continue to alter our motivations and perceptions. Henrich shows how our genetics and biology are inextricably interwoven with cultural evolution, and how culture-gene interactions launched our species on an extraordinary evolutionary trajectory. Tracking clues from our ancient past to the present, The Secret of Our Success explores how the evolution of both our cultural and social natures produce a collective intelligence that explains both our species' immense success and the origins of human uniqueness.

Humans are a striking anomaly in the natural world. While we are similar to other mammals in many ways, our behavior sets us apart. Our unparalleled ability to adapt has allowed us to occupy virtually every habitat on earth using an incredible variety of tools and subsistence techniques. Our societies are larger, more complex, and more cooperative than any other mammal's. In this stunning exploration of human adaptation, Peter J. Richerson and Robert Boyd argue that only a Darwinian theory of cultural evolution can explain these unique characteristics. Not by Genes Alone offers a radical interpretation of human evolution, arguing that our ecological dominance and our singular social systems stem from a psychology uniquely adapted to create complex culture. Richerson and Boyd illustrate here that culture is neither superorganic nor the handmaiden of the genes. Rather, it is essential to human adaptation, as much a part of human biology as bipedal locomotion. Drawing on work in the fields of anthropology, political science, sociology, and economics—and building their case with such fascinating examples as kayaks, corporations, clever knots, and yams that require twelve men to carry them—Richerson and Boyd convincingly demonstrate that culture and biology are inextricably linked, and they show us how to think about their interaction in a way that yields a richer understanding of human nature. In abandoning the nature-versus-nurture debate as fundamentally misconceived, Not by Genes Alone is a truly original and groundbreaking theory of the role of culture in evolution and a book to be reckoned with for generations to come. “I continue to be surprised by the number of educated people (many of them biologists) who think that offering explanations for human behavior in terms of culture somehow disproves the suggestion that human behavior can be explained in Darwinian evolutionary terms. Fortunately, we now have a book to which they may be directed for enlightenment . . . . It is a book full of good sense and the kinds of intellectual rigor and clarity of writing that we have come to expect from the Boyd/Richerson stable.”—Robin Dunbar, Nature “Not by Genes Alone is a valuable and very readable synthesis of a still embryonic but very important subject straddling the sciences and humanities.”—E. O. Wilson, Harvard University

Twelve original essays examine the symbiotic relation of culture and genome.

This volume brings together a collection of seven articles previously published by the author, with a new introduction reframing the articles in the context of past and present questions in anthropology, psychology and human evolution. It promotes the perspective of ‘integrated’ social science, in which social science questions are addressed in a deliberately eclectic manner, combining results and models from evolutionary biology, experimental psychology, economics, anthropology and history. It thus constitutes a welcome contribution to a gradually emerging approach to social science based on E. O. Wilson’s concept of ‘consilience’. Human Cultures through the Scientific Lens spans a wide range of topics, from an examination of ritual behaviour, integrating neuro-science, ethology and anthropology to explain why humans engage in ritual actions (both cultural and individual), to the motivation of conflicts between groups. As such, the collection gives readers a comprehensive and accessible introduction to the applications of an evolutionary paradigm in the social sciences. This volume will be a useful resource for scholars and students in the social sciences (particularly psychology, anthropology, evolutionary biology and the political sciences), as well as a general readership interested in the social sciences.

A complete account of evolutionary thought in the social, environmental and policy sciences, creating bridges with biology.

Evolution and Human Culture argues that values, beliefs, and practices are expressions of individual and shared moral sentiments. Much of our cultural production stems from what in early hominins was a caring tendency, both the care to share and a self-care to challenge others. Topics cover prehistory, mind, biology, morality, comparative primatology, art, and aesthetics. The book is valuable to students and scholars in the arts, including moral philosophers, who would benefit from reading about scientific developments that impact their fields. For biologists and social scientists the book provides a window into how scientific research contributes to understanding the arts and humanities. The take-home point is that culture does not transcend nature; rather, culture is an evolved moral behavior.

Oxford presents, in one convenient and coherently organized volume, 20 influential but until now relatively inaccessible articles that form the backbone of Boyd and Richerson's path-breaking work on evolution and culture. Their interdisciplinary research is based on two notions. First, that culture is crucial for understanding human behavior; unlike other organisms, socially transmitted beliefs, attitudes, and values heavily influence our behavior. Secondly, culture is part of biology: the capacity to acquire and transmit culture is a derived component of human psychology, and the contents of culture are deeply intertwined with our biology. Culture then is a pool of information, stored in the brains of the population that gets transmitted from one brain to another by social learning processes. Therefore, culture can account for both our outstanding ecological success as well as the maladaptations that characterize much of human behavior. The interest in this collection will span anthropology, psychology, economics, philosophy, and political science.
