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.

Few things come more naturally to us than sex—or so it would seem. Yet to a chimpanzee, the sexual practices and customs we take for granted would appear odd indeed. He or she might wonder why we bother with inconveniences like clothes, why we prefer to make love on a bed, and why we fuss so needlessly over privacy. Evolution and Human Sexual Behavior invites us into the thought-experiment of imagining human sex from the vantage point of our primate cousins, in order to underscore the role of evolution in shaping all that happens, biologically and behaviorally, when romantic passions are aroused. Peter Gray and Justin Garcia provide an interdisciplinary synthesis that draws on the latest discoveries in evolutionary theory, genetics, neuroscience, comparative primate research, and cross-cultural sexuality studies. They are our guides through an exploration of the patterns and variations that exist in human sexuality, in chapters covering topics ranging from the evolution of sex differences and reproductive physiology to the origins of sexual play, monogamous unions, and the facts and fictions surrounding orgasm. Intended for generally curious readers of all stripes, this up-to-date, one-volume survey of the evolutionary science of human sexual behavior explains why sexuality has remained a core fascination of human beings throughout time and across cultures.

A lively and entertaining account of the broad panorama of human sexual behaviour which reveals our actions to be an inextricable mixture of nature and nurture - a combination of innate actions evolved over the millenia, overlain by more recent cultural constraints imposed by civilization.

Expand your knowledge—with theories and concepts that may challenge your assumptions about sexual attraction Human sexuality can be better understood by knowing how sexual psychologies may have evolved throughout the ages. Handbook of the Evolution of Human Sexuality presents a detailed examination of human sexuality, the assumptions about concepts and terms pertaining to sexuality, and the latest theories on the evolution of human sexual attraction. Leading experts explore various aspects of evolutionary theory, with a focus on Evolutionary Psychology (EP). Discussions include mate preferences, mating behavior, mate signaling, pheromones, and same-sex attraction. This comprehensive source also presents three groundbreaking theories of the evolution of same-sex attraction. Handbook of the Evolution of Human Sexuality takes current assumptions about human sexuality, explains each in turn, and then offers fresh perspectives on conventional concepts of sexual orientation. This extensive resource provides ample evidence to argue that researchers should investigate sexual relationships based on a person’s characteristics such as personal traits, complementary roles/status, sexual acts, or situational context rather than simply the sex of the partner. The book provides a discussion of evolutionary theory, evolution of human sexual culture, evolution of sexual pleasure, and detailed analysis of assumptions about sexual orientation. The text is carefully referenced. Some of the topics explored by Handbook of the Evolution of Human Sexuality include: links to non-human primate sexual behaviors and the emergence of human (sexual) nature EP research on consensual adult human sexual behaviors studies of evolved male and female mating strategies, mate preferences, and sexual psychologies a brief history of the theory of evolution ancient culture, archeology, and an overview of premodern human sexuality evolutionary history of sexual pleasure human mating strategies development of mate preferences sexual signals, such as distinctive physical features, material wealth, etc. theories of the evolution of same-sex sexual attraction and behavior Primatologist Paul Vasey’s observations of female Japanese macaques and their female-female sexual encounters—with an examination of human male-male behavior evolutionary history of female-female affectional bonding with a new theory on the behavior evolutionary history of male-male sexual behavior—with intriguing thoughts on why it happened evolutionary history of pheromones as chemical messengers much more Handbook of the Evolution of Human Sexuality is an important, thought-provoking resource perfect for evolutionary psychologists, sexologists, educators, researchers, scholars, and graduate students.

This book provides a comprehensive analysis of the evolutionary origins of same-sex attraction, evaluating multiple existing evolutionary theories. It combines empirical findings with theoretical arguments in order to review evidence on the prevalence rates of same-sex attraction and determine its genetic and environmental basis. Among the topics addressed: Attitudes towards same-sex attraction across human history Assessing the weak selection pressures hypothesis of attraction Assessing the male choice hypothesis of attraction Evolution of same-sex attraction in men versus women The Evolution of Same-Sex Attraction will be of interest to academics and students of evolutionary and psychological sciences, filling a gap in literature on the origins of specifically same-sex attraction.

In this innovative celebration of diversity and affirmation of individuality in animals and humans, Joan Roughgarden challenges accepted wisdom about gender identity and sexual orientation. A distinguished evolutionary biologist, Roughgarden takes on the medical establishment, the Bible, social science—and even Darwin himself. She leads the reader through a fascinating discussion of diversity in gender and sexuality among fish, reptiles, amphibians, birds, and mammals, including primates. Evolution's Rainbow explains how this diversity develops from the action of genes and hormones and how people come to differ from each other in all aspects of body and behavior. Roughgarden reconstructs primary science in light of feminist, gay, and transgender criticism and redefines our understanding of sex, gender, and sexuality. Witty, playful, and daring, this book will revolutionize our understanding of sexuality. Roughgarden argues that principal elements of Darwinian sexual selection theory are false and suggests a new theory that emphasizes social inclusion and control of access to resources and mating opportunity. She disputes a range of scientific and medical concepts, including Wilson's genetic determinism of behavior, evolutionary psychology, the existence of a gay gene, the role of parenting in determining gender identity, and Dawkins's "selfish gene" as the driver of natural selection. She dares social science to respect the agency and rationality of diverse people; shows that many cultures across the world and throughout history accommodate people we label today as lesbian, gay, and transgendered; and calls on the Christian religion to acknowledge the Bible's many passages endorsing diversity in gender and sexuality. Evolution's Rainbow concludes with bold recommendations for improving education in biology, psychology, and medicine; for democratizing genetic engineering and medical practice; and for building a public monument to affirm diversity as one of our nation's defining principles.

Originally published in 1982, The Masterpiece of Nature examines sex as representative of the most important challenge to the modern theory of evolution. The book suggests that sex evolved, not as the result of normal Darwinian processes of natural selection, but through competition between populations or species - a hypothesis elsewhere almost universally discredited. The book also discusses the nature of sex and its consequences for the individual and for the population, as well as various other theories of sex. Since the value of these theories is held to reside wholly in their ability to predict the patterns of sexuality observed in nature, the book seeks to provide an extensive review of the circumstances in which sexuality is attenuated or lost throughout the animal kingdom, and these facts are then used to weigh up the merits of the rival theories. This book will be of interest to researchers in the area of genetics, ecology and evolutionary biology.
