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.

When evolutionary biology stretched out a tentacle called sociobiology and began to probe human behavior back in the 1970s, there was no room for neutrality. Advocates of the new science hailed the dawn of a new era in our understanding of human behavior, while opponents wrung their hands with concern over the new field's potential to transform and

Can one change one's ethnicity? Can an entire ethnic group change its ethnicity? This book focuses on the strategic manipulation of ethnic identity by the Mukogodo of Kenya. Until the 1920s and 1930s, the Mukogodo were Cushitic-speaking foragers (hunters, gatherers, and beekeepers). However, changes brought on by British colonial policies led them

Can one change one's ethnicity? Can an entire ethnic group change its ethnicity? This book focuses on the strategic manipulation of ethnic identity by the Mukogodo of Kenya. Until the 1920s and 1930s, the Mukogodo were Cushitic-speaking foragers (hunters, gatherers, and beekeepers). However, changes brought on by British colonial policies led them to move away from life as independent foragers and into the orbit of the high-status Maasai, whom they began to emulate. Today, the Mukogodo form the bottom rung of a regional socioeconomic ladder of Maa-speaking pastoralists. An interesting by-product of this sudden ethnic change has been to give Mukogodo women, who tend to marry up the ladder, better marital and reproductive prospects than Mukogodo men. Mukogodo parents have responded with an unusual pattern of favoring daughters over sons, though they emulate the Maasai by verbally expressing a preference for sons.

When evolutionary biology stretched out a tentacle called sociobiology and began to probe human behavior back in the 1970s, there was no room for neutrality. Advocates of the new science hailed the dawn of a new era in our understanding of human behavior, while opponents wrung their hands with concern over the new field's potential to transform and even destroy anthropology and other social and behavioral sciences. Twenty years later, little has changed. Anthropology and its sister disciplines are still intact and thriving, though they seldom make use of insights from evolutionary biology. Cultural anthropology in particular has recoiled from the biological threat by moving away from the sciences and toward the humanities. During that same time, a new generation of scholars in biological anthropology, psychology, and other fields has made great progress by using evolutionary theory to understand human behavior, applying it to everything from mating and parenting to the study of mental illness. The success of this research program is threatened, however, by its lack of a serious role for the concept of culture."That Complex Whole: Culture and the Evolution of Human Behavior" is an effort to develop a scientific study of human behavior that is at once evolutionary and cultural. In a lively, readable style, it deals with such serious, scholarly issues as how to best define culture, the question of whether culture is present in other species, human universals and human diversity, the relationship between culture and behavior, and cultural and moral relativism. It covers existing models of the relationship between cultural and biological evolution, including the concept of the meme and the new science of memetics, as well as the author's own work on the role of culture in human communications that draws upon the study of animal signals.

From the family to the workplace to the marketplace, every facet of our lives is shaped by cooperative interactions. Yet everywhere we look, we are confronted by proof of how difficult cooperation can be--snarled traffic, polarized politics, overexploited resources, social problems that go ignored. The benefits to oneself of a free ride on the efforts of others mean that collective goals often are not met. But compared to most other species, people actually cooperate a great deal. Why is this? Meeting at Grand Central brings together insights from evolutionary biology, political science, economics, anthropology, and other fields to explain how the interactions between our evolved selves and the institutional structures we have created make cooperation possible. The book begins with a look at the ideas of Mancur Olson and George Williams, who shifted the question of why cooperation happens from an emphasis on group benefits to individual costs. It then explores how these ideas have influenced our thinking about cooperation, coordination, and collective action. The book persuasively argues that cooperation and its failures are best explained by evolutionary and social theories working together. Selection sometimes favors cooperative tendencies, while institutions, norms, and incentives encourage and make possible actual cooperation. Meeting at Grand Central will inspire researchers from different disciplines and intellectual traditions to share ideas and advance our understanding of cooperative behavior in a world that is more complex than ever before.
