The Darwinian legacy 1.

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.

1. INTRODUCTION This book describes a new interdisciplinary theory for explaining cultural change. In contrast to traditional evolutionist theories, the present theory stresses the fact that a culture can evolve in different directions depending on its life conditions. Cultural selection theory explains why certain cultures or cultural ele ments spread, possibly at the expense of other cultures or cultural elements which then disappear. Cultural elements include social structure, traditions, religion, rituals, art, norms, morals, ideologies, ideas, inventions, knowledge, technology, etc. This theory is inspired by Charles Darwin's idea of natural selection, because cultural elements are seen as analogous to genes in the sense that they may be reproduced from generation to generation and they may undergo change. A culture may evolve because certain cultural elements are more likely to spread and be reproduced than others, analogously to a species evolving because individuals possessing certain traits are more fit than others to reproduce and transmit these traits to their offspring.

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

"In The Theory of Cultural and Social Selection, W.G. Runciman presents an original and wide-ranging account of the fundamental process by which human cultures and societies come to be of the different kinds that they are. Drawing on and extending recent advances in neo-Darwinian evolutionary theory, Runciman argues that collective human behaviour should be analyzed as the acting-out of information transmitted at the three separate but interacting levels of heritable variation and competitive selection - the biological, the cultural, and the social. The implications which this carries for a reformulation of the traditional agenda of comparative and historical sociology are explored with the help of selected examples, and located within the context of current debates about sociological theory and practice. The Theory of Cultural and Social Selection is a succinct and highly imaginative contribution to one of the great intellectual debates of our times, from one of the world's leading social theorists"--Provided by publisher.

Charles Darwin changed the course of scientific thinking by showing how evolution accounts for the stunning diversity and biological complexity of life on earth. Recently, there has also been increased interest in the social sciences in how Darwinian theory can explain human culture. Covering a wide range of topics, including fads, public policy, the spread of religion, and herd behavior in markets, Alex Mesoudi shows that human culture is itself an evolutionary process that exhibits the key Darwinian mechanisms of variation, competition, and inheritance. This cross-disciplinary volume focuses on the ways cultural phenomena can be studied scientifically—from theoretical modeling to lab experiments, archaeological fieldwork to ethnographic studies—and shows how apparently disparate methods can complement one another to the mutual benefit of the various social science disciplines. Along the way, the book reveals how new insights arise from looking at culture from an evolutionary angle. Cultural Evolution provides a thought-provoking argument that Darwinian evolutionary theory can both unify different branches of inquiry and enhance understanding of human behavior.

A number of scholars have found that concepts such as mutation, selection, and random drift, which emerged from the theory of biological evolution, may also explain evolutionary phenomena in other disciplines as well. Drawing on these concepts, Professors Cavalli-Sforza and Feldman classify and systematize the various modes of transmitting "culture" and explore their consequences for cultural evolution. In the process, they develop a mathematical theory of the non-genetic transmission of cultural traits that provides a framework for future investigations in quantitative social and anthropological science. The authors use quantitative models that incorporate the various modes of transmission (for example, parent-child, peer-peer, and teacher-student), and evaluate data from sociology, archaeology, and epidemiology in terms of the models. They show that the various modes of transmission in conjunction with cultural and natural selection produce various rates of cultural evolution and various degrees of diversity within and between groups. The same framework can be used for explaining phenomena as apparently unrelated as linguistics, epidemics, social values and customs, and diffusion of innovations. The authors conclude that cultural transmission is an essential factor in the study of cultural change.

Social scientists can learn a lot from evolutionary biology - from systematics and principles of evolutionary ecology to theories of social interaction including competition, conflict and cooperation, as well as niche construction, complexity, eco-evo-devo, and the role of the individual in evolutionary processes. Darwinian sociocultural evolutionary theory applies the logic of Darwinism to social-learning based cultural and social change. With a multidisciplinary approach for graduate biologists, philosophers, sociologists, anthropologists, social psychologists, archaeologists, linguists, economists, political scientists and science and technology specialists, the author presents this model of evolution drawing on a number of sophisticated aspects of biological evolutionary theory. The approach brings together a broad and inclusive theoretical framework for understanding the social sciences which addresses many of the dilemmas at their forefront - the relationship between history and necessity, conflict and cooperation, the ideal and the material and the problems of agency, subjectivity and the nature of social structure.

What does Western science know about the relationship between individual well-being and cultural trends? What can learn from other cultural traditions? What do the recent advancements in positive psychology teach us on this issue, particularly the eudaimonic framework, which emphasizes the connections between personal well-being and social welfare? People grow and live in cultures that deeply influence their values, aspirations and behaviors. However, individuals in their turn play an active role in building their own goals, growth trajectories and social roles, at the same time influencing culture trends. This process, defined psychological selection, is related to the individual pursuit of well-being People preferentially select and cultivate in their lives activities, interests, and relationships associated with optimal experience, a state of deep engagement, concentration, and enjoyment. Several cross-cultural studies confirmed the positive and rewarding features of optimal experience. Based on these evidences, this book offers a new perspective in the study of human behavior. Highlighting the interplay between individual and cultural growth trajectories, it conveys a core message: educating people to enjoy engagement and involvement in activities that can be relevant and meaningful for social welfare is a premise to foster the harmonious development of human communities, and the peaceful cohabitation of cultures.
