This volume presents state-of-the-art empirical studies working in a paradigm that has become known as human behavioral ecology. The emergence of this approach in anthropology was marked by publication by Aldine in 1979 of an earlier collection of studies edited by Chagnon and Irons entitled Evolutionary Biology and Human Social Behavior: An Anthropological Perspective. During the two decades that have passed since then, this innovative approach has matured and expanded into new areas that are explored here. The book opens with an introductory chapter by Chagnon and Irons tracing the origins of human behavioral ecology and its subsequent development. Subsequent chapters, written by both younger scholars and established researchers, cover a wide range of societies and topics organ-ized into six sections. The first section includes two chapters that provide historical background on the development of human behavioral ecology and com-pare it to two complementary approaches in the study of evolution and human behavior, evolutionary psychology, and dual inheritance theory. The second section includes five studies of mating efforts in a variety of societies from South America and Africa. The third section covers parenting, with five studies on soci-eties from Africa, Asia, and North America. The fourth section breaks somewhat with the tradition in human behavioral ecology by focusing on one particularly problematic issue, the demographic transition, using data from Europe, North America, and Asia. The fifth section includes studies of cooperation and helping behaviors, using data from societies in Micronesia and South America. The sixth and final section consists of a single chapter that places the volume in a broader critical and comparative context. The contributions to this volume demonstrate, with a high degree of theoretical and methodological sophistication--the maturity and freshness of this new paradigm in the study of human behavior. The volume will be of interest to anthropologists and other professions working on the study of cross-cultural human behavior.

In this stimulating book, Goldsmith argues that biology has a great deal to say that should be of interest to social scientists, historians, philosophers, and humanists in general. He believes that anyone studying the social behavior of humans must take into consideration both proximate cause--the physiology, biochemistry, and social mechanisms of behavior--and ultimate cause--how the behavior came to exist in evolutionary time. Goldsmith, a neurobiologist, draws examples from neurobiology, psychology, and ethology (behavioral evolution). The result is a work that overcomes many of the misconceptions that have hindered the rich contributions the biological sciences have to offer concerning the evolution of human society, behavior, and sense of identity. Among the key topics addressed are the nature of biological explanation, the relationship between genes and behavior, those aspects of behavior most likely to respond to natural selection, the relationship between evolution and learning, and some probable modes of interaction between cultural and biological evolution. By re-examining the role of biological explanation in the domain of social development, the author has significantly advanced a more well-rounded view of human evolution and shed new light on the perennial question of what it means to be human. His book will appeal to biologists, social scientists, traditional humanists, and interested general readers.

These six original essays focus on a potentially important aspect of evolutionary biology, the possible causal role of phenotypic behavior in evolution. Balancing theory with actual or potential empiricism, they provide the first full examination of this topic. Plotkin's opening chapter outlines the "conceptual minefields" that the contributors attempt to negotiate: What is an adequate theory of evolution? What is behavior and is it possible to maintain a distinction between behavior and other attributes of the phenotype? is all, or only a special subset, of behavior both a cause and a consequence of evolution? And what do the theoretical issues mean in empirical terms? He concludes that any attempt to understand the causal role of behavior in evolution requires a more complicated theoretical structure than that of orthodox neoDarwinism, a conceptualization of behavior as a distinctive set of phenotypic attributes, and the accumulation of more data. David L. Hull (Northwestern University) provides an alternative account of the evolutionary process by developing a hierarchy of replicators-interactors-lineages to replace the traditional one of genes-organisms-species. Robert N. Brandon (Duke University) also posits hierarchy as an appropriate architecture for the theoretical complexity needed to support an examination of the role of behavior in evolution. F. J. Odling-Smee (Brunei University) outlines a theoretical structure to encompass the behavior of phenotypes, concentrating on the unrestricted definition of behavior (everything that an animal does). The remaining chapters are as much concerned with evidence as with theory. Plotkin concentrates on a restricted definition of behavior (behavior that is a product of choosing intelligence), reviewing our empirical knowledge of how learning might influence evolution. R.I.M. Dunbar (University College, London) uses empirical studies of vertebrate social behavior to deal with the question of how the social systems, especially of primates, might have a causal role in species evolution.

How can the stunning diversity of social systems and behaviours seen in nature be explained? Drawing on social evolution theory, experimental evidence and studies conducted in the field, this book outlines the fundamental principles of social evolution underlying this phenomenal richness.To succeed in the competition for resources, organisms may either 'race' to be quicker than others, 'fight' for privileged access, or 'share' their efforts and gains. The authors show how the ecology and intrinsic attributes of organisms select for each of these strategies, and how a handful of straightforward concepts explain the evolution of successful decision rules in behavioural interactions, whether among members of the same or different species. With a broad focus ranging from microorganisms to humans, this is the first book to provide students and researchers with a comprehensive account of the evolution of sociality by natural selection.

Our understanding of the evolution of human behavior has grown enormously over the past few decades, and an increasing number of behavioral and social scientists are making use of evolutionary theory in their work to shed light on issues ranging from marriage and parenting to the study of mental illness. The success of this research program is thre
