Examines the importance of evolutionary biology for key issues in human development. Illustrates the power of socio- biological approaches in understanding developmental pheno- mena and their importance in generating new, empirically verifiable predictions.

Attraction, mating, reproduction: it is a given that as a species, human beings are concerned with sex. And whether the study compares sexual behaviors of men and women or considers the proportions between nature and nurture, most roads lead back to our distant ancestors and/or our fellow animals. The Evolution of Sexuality collects stimulating new empirical findings and theoretical concepts regarding both familiar themes and emerging areas of interest. Following earlier titles in this series, an interdisciplinary panel of contributors examines topics specific to the whys of male and female sex-related behavior, here ranging from biological bases for male same-sex attraction to the seemingly elusive purpose of the female orgasm. This vantage point between biology and psychology gives readers profound insights not just into human differences and similarities, but also why they continue to matter despite our vast understanding of culture and socialization. And intriguing dispatches from the humanities review sexual themes in classic works of literature and explore the role of parent-offspring conflict in the English Revolution of the seventeenth century. Among the topics covered: Sexual conflict and evolutionary psychology: toward a unified framework. Assortative mating, caste, and class. The functional design and phylogeny of female sexuality. Is oral sex a form of mate retention behavior? Two behavioral hypotheses for the evolution or male homosexuality in humans. Sperm competition and the evolution of human sexuality. The Evolution of Sexuality will attract evolutionary scientists across a variety of disciplines. Faculty, graduate and undergraduate students, and researchers interested in sexuality will find it a springboard for discussion, debate, and further study.

To most biologists, sociobiology represents the concept of strict Darwinian individual selection married to an analytical application of ecological principles and brought to bear on social behavior in an unusually exciting and productive way. Joining the biologists are a small number of social scientists. But there are radically divergent views as to how the field should be delimited, and sociobiology is one of the most widely discussed fields in biology and anthropology today. The symposium on which this book is based was arranged by a biologist and an anthropologist. The participants, leaders in their fields, ably present contrasting and responsible views on current issues. This is the first collection of essays on sociobiology in which opposing views are aired. It is an exciting, timely book and an important historical document.

Why are men, like other primate males, usually the aggressors and risk takers? Why do women typically have fewer sexual partners? In Why Sex Matters, Bobbi Low ranges from ancient Rome to modern America, from the Amazon to the Arctic, and from single-celled organisms to international politics, to show that these and many other questions about human behavior largely come down to evolution and sex. More precisely, as she shows in this uniquely comprehensive and accessible survey of behavioral and evolutionary ecology, they come down to the basic principle that all organisms evolved to maximize their reproductive success and seek resources to do so, but that sometimes cooperation and collaboration are the most effective ways to succeed. This newly revised edition has been thoroughly updated to include the latest research and reflect exciting changes in the field, including how our evolutionary past continues to affect our ecological present.

A central aspect of human adaptation - reproductive behaviour - is studied through the multiple lenses of philosophy, biology, psychology and anthropology, all united by an evolutionary perspective. Although reproduction is an intrinsic mechanism of evolution, this colloquium shows that reproductive behaviours yield new significance for evolution theory when re-examined in a multidisciplinary setting. This volume focuses on explication of the adaptive, evolved nature of our own reproduction with topics such as how mate choice shaped human nature; symmetry in mate selection; the evolution of moral dispositions; and the sexist order of the bonobos. This look at reproduction as a mechanism of human evolution reveals underlying physiologic mechanisms, as well as comparative and interesting cross-cultural aspects that emerge from social sciences and anthropology.
