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.

Research conducted in the last fifteen years has placed in question many of the traditional conclusions scholars have formed about human female sexuality. Though conventional wisdom asserts that women's estrus has been evolutionarily lost, Randy Thornhill and Steven W. Gangestad assert that it is present, though concealed. Women, they propose, therefore exhibit two sexualities each ovulatory cycle-estrus and sexuality outside of the estrous phase, extended sexuality-that possess distinct functions. Synthesizing research in behavioral evolution and comparative biology, the authors provide a new theoretical framework for understanding the evolution of human female sexuality, one that is rooted in female sexuality and phylogeny across all vertebrate animals.

As in the bestselling The Alphabet Versus the Goddess, Leonard Shlain’s provocative new book promises to change the way readers view themselves and where they came from. Sex, Time, and Power offers a tantalizing answer to an age-old question: Why did big-brained Homo sapiens suddenly emerge some 150,000 years ago? The key, according to Shlain, is female sexuality. Drawing on an awesome breadth of research, he shows how, long ago, the narrowness of the newly bipedal human female’s pelvis and the increasing size of infants’ heads precipitated a crisis for the species. Natural selection allowed for the adaptation of the human female to this environmental stress by reconfiguring her hormonal cycles, entraining them with the periodicity of the moon. The results, however, did much more than ensure our existence; they imbued women with the concept of time, and gave them control over sex—a power that males sought to reclaim. And the possibility of achieving immortality through heirs drove men to construct patriarchal cultures that went on to dominate so much of human history. From the nature of courtship to the evolution of language, Shlain’s brilliant and wide-ranging exploration stimulates new thinking about very old matters.

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.

Why women evolved to have orgasms--when most of their primate relatives don't--is a persistent mystery among evolutionary biologists. In pursuing this mystery, Elisabeth Lloyd arrives at another: How could anything as inadequate as the evolutionary explanations of the female orgasm have passed muster as science? A judicious and revealing look at all twenty evolutionary accounts of the trait of human female orgasm, Lloyd's book is at the same time a case study of how certain biases steer science astray. Over the past fifteen years, the effect of sexist or male-centered approaches to science has been hotly debated. Drawing especially on data from nonhuman primates and human sexology over eighty years, Lloyd shows what damage such bias does in the study of female orgasm. She also exposes a second pernicious form of bias that permeates the literature on female orgasms: a bias toward adaptationism. Here Lloyd's critique comes alive, demonstrating how most of the evolutionary accounts either are in conflict with, or lack, certain types of evidence necessary to make their cases--how they simply assume that female orgasm must exist because it helped females in the past reproduce. As she weighs the evidence, Lloyd takes on nearly everyone who has written on the subject: evolutionists, animal behaviorists, and feminists alike. Her clearly and cogently written book is at once a convincing case study of bias in science and a sweeping summary and analysis of what is known about the evolution of the intriguing trait of female orgasm.

In this multidisciplinary study of human sexuality, an international team of scholars looks at the influences of nature and nurture, biology and culture, and sex and gender in the sexual experiences of humans and other primates. Using as its center the idea that sexual pleasure is the primary motivational force behind human sexuality and that reproduction is simply a byproduct of the pleasurability of sex, this book examines sexuality at the individual, societal, and cultural levels. Beginning with a look at the evolution of sexuality in humans and other primates, the essays in the first section examine the sexual ingenuity of primates, the dominant theories of sexual behavior, the differences in male and female sexual interest and behavior, and the role of physical attractiveness in mate selection. The focus then shifts to biological approaches to sexuality, especially the genetic and hormonal origins of sexual orientation, gender, and pleasure. The essays go on to look at the role of pleasure in different cultures. Included are essays on love among the tribespeople of the Brazilian rain forest and the regulation of adolescent sexuality in India. Finally, several contributors look at the methodological issues in the study of human sexuality, paying particular attention to the problems with research that relies on people's memories of their sexual experiences. The contributors are Angela Pattatucci, Dean Hamer, David Greenberg, Frans de Waal, Mary McDonald Pavelka, Kim Wallen, Donald Symons, Heino Meyer-Bahlburg, Jean D. Wilson, Donald Tuzin, Lawrence Cohen, Thomas Gregor, Lenore Manderson, Robert C. Bailey, Alice Schlegel, Edward H. Kaplan, Richard Berk, Paul R. Abramson, Paul Okami, and Stephen D. Pinkerton. Spanning the chasm of the nature versus nurture debate, Sexual Nature/Sexual Culture is a look at human sexuality as a complex interaction of genetic potentials and cultural influences. This book will be of interest to a wide range of readers—from scholars and students in psychology, anthropology, sociology, and history to clinicians, researchers, and others seeking to understand the many dimensions of sexuality. "If we ever expect to solve the sexually based problems that modern societies face, we must encourage investigations of human sexual behavior. Moreover, those investigations should employ a broad range of disciplines—looking at sex from all angles, which is precisely what Sexual Nature, Sexual Culture does."—Mike May, American Scientist "...This timely and relevant book reminds us that we cannot rely on simple solutions to complex problems. It represents a transdiciplinary approach integrating knowledge from diverse fields and provides the reader with a challenging and rewarding experience. Especially for those who are involved in teaching human sexuality to medical students and other health care professionals, this book is highly recommended."—Gerald Wiviortt, M.D., Journal of Nervous and Mental Disease "In short, this volume contains much to stimulate, inform, and amuse, in varying proportions. What more can one ask?"—Pierre L. van den Berghe, Journal of the History of Sexuality "...the book succeeds in bring together some of the sharpest thinkers in the field of human sexuality, and goes a long way toward clarifying the diverse perspectives that currently exist."—David M. Buss and Todd K. Shackelford, Quarterly Review of Biology

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.
