How do biological, psychological, sociological, and cultural factors combine to change societies over the long run? Boyd and Richerson explore how genetic and cultural factors interact, under the influence of evolutionary forces, to produce the diversity we see in human cultures. Using methods developed by population biologists, they propose a theory of cultural evolution that is an original and fair-minded alternative to the sociobiology debate.

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, and our societies are larger, more complex, and more cooperative than any other mammal's. In "Not by Genes Alone", 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 consider culture to be 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, clever knots, and yams that require twelve men to carry them - Richerson and Boyd convincingly demonstrate that culture and biology are inextricably linked.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.

What motives underlie the ways humans interact socially? Are these the same for all societies? Are these part of our nature, or influenced by our environments?Over the last decade, research in experimental economics has emphatically falsified the textbook representation of Homo economicus. Literally hundreds of experiments suggest that people care not only about their own material payoffs, but also about such things as fairness, equity and reciprocity. However, this research left fundamental questions unanswered: Are such social preferences stable components of human nature; or, are they modulated by economic, social and culturalenvironments?Until now, experimental research could not address this question because virtually all subjects had been university students, and while there are cultural differences among student populations throughout the world, these differences are small compared to the full range of human social and cultural environments. A vast amount of ethnographic and historical research suggests that people''s motives are influenced by economic, social, and cultural environments, yet such methods can only yieldcircumstantial evidence about human motives.Combining ethnographic and experimental approaches to fill this gap, this book breaks new ground in reporting the results of a large cross-cultural study aimed at determining the sources of social (non-selfish) preferences that underlie the diversity of human sociality. The same experiments which provided evidence for social preferences among university students were performed in fifteen small-scale societies exhibiting a wide variety of social, economic and cultural conditions by experiencedfield researchers who had also done long-term ethnographic field work in these societies.The findings of these experiments demonstrated that no society in which experimental behaviour is consistent with the canonical model of self-interest. Indeed, results showed that the variation in behaviour is far greater than previously thought, and that the differences between societies in market integration and the importance of cooperation explain a substantial portion of this variation, which individual-level economic and demographic variables could not. Finally, the extent to whichexperimental play mirrors patterns of interaction found in everyday life is traced.The book starts with a succinct but substantive introduction to the use of game theory as an analytical tool and its use in the social sciences for the rigorous testing of hypotheses about fundamental aspects of social behaviour outside artificially constructed laboratories. The results of the fifteen case studies are summarized in a suggestive chapter about the scope of the project.

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.

Over the last several decades, mathematical models have become central to the study of social evolution, both in biology and the social sciences. But students in these disciplines often seriously lack the tools to understand them. A primer on behavioral modeling that includes both mathematics and evolutionary theory, "Mathematical Models of Social Evolution" aims to make the student and professional researcher in biology and the social sciences fully conversant in the language of the field. Teaching biological concepts from which models can be developed, Richard McElreath and Robert Boyd introduce readers to many of the typical mathematical tools that are used to analyze evolutionary models and end each chapter with a set of problems that draw upon these techniques. "Mathematical Models of Social Evolution" equips behaviorists and evolutionary biologists with the mathematical knowledge to truly understand the models on which their research depends.Ultimately, McElreath and Boyd's goal is to impart the fundamental concepts that underlie modern biological understandings of the evolution of behavior so that readers will be able to more fully appreciate journal articles and scientific literature and start building models of their own.

How our ability to learn from each other has been the essential ingredient to our remarkable success as a species Human beings are a very different kind of animal. We have evolved to become the most dominant species on Earth. We have a larger geographical range and process more energy than any other creature alive. This astonishing transformation is usually explained in terms of cognitive ability--people are just smarter than all the rest. But in this compelling book, Robert Boyd argues that culture--our ability to learn from each other--has been the essential ingredient of our remarkable success. A Different Kind of Animal demonstrates that while people are smart, we are not nearly smart enough to have solved the vast array of problems that confronted our species as it spread across the globe. Over the past two million years, culture has evolved to enable human populations to accumulate superb local adaptations that no individual could ever have invented on their own. It has also made possible the evolution of social norms that allow humans to make common cause with large groups of unrelated individuals, a kind of society not seen anywhere else in nature.This unique combination of cultural adaptation and large-scale cooperation has transformed our species and assured our survival--making us the different kind of animal we are today. Based on the Tanner Lectures delivered at Princeton University, A Different Kind of Animal features challenging responses by biologist Allen Orr, philosopher Kim Sterelny, economist Paul Seabright, and evolutionary anthropologist Ruth Mace, as well as an introduction by Stephen Macedo.

People of The Dalles is the story of the Chinookan (Wasco-Wishram) and Sahaptin peoples of The Dalles area of the Columbia River, who encountered the Lewis & Clark expedition in 1805–6. The early history and culture of these communities is reconstructed from the accounts of explorers, travelers, and the early writings of the Methodist missionaries at Wascopam, in particular the papers of Reverend Henry Perkins. Boyd covers early nineteenth century cultural geography, subsistence, economy, social structure, life-cycle rituals, and religion. People of The Dalles also details the changes that occurred to these people's traditional life-ways, including their relationship with Methodism following the devastating epidemics of the early 1830s. Today, descendants of the Chinookan and Sahaptin peoples are enrolled in the Confederated Tribes of Warm Springs and the Yakama Nation.
