This title introduces a theoretical framework for understanding women's sexuality based on comparative female sexuality across all vertebrate animals. It shows that estrus is present in human females, contrary to earlier research.
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.
This volume in the Springer Series in Evolutionary Psychology presents a state of the art view of the topic of sexuality and sexual behavior drawing on theoretical constructs and research of noted individuals in the field. Comprehensive and multi-disciplinary, this book seeks to provide a broad overview without sacrificing the complexity of a multi-faceted approach. The book is framed by introductory and closing sections that provide a context for the range of ideas contained within. Ample space is provided in designated sections that focus on key areas of sexuality from both male and female perspectives and that include information from primate studies. This volume can serve as a graduate text in sexual behavior in evolutionary terms and as a guide for further research.
Geary (psychology and anthropology, U. of Missouri-Columbia) thinks culturally constructed gender roles alone cannot account for the differences in the social behavior of men and women. He turns to Darwin's theory of sexual selection as the best avenue for understanding. His main focus is how th etwo elements of competition between males and of females selecting mates has influenced human behavior over the centuries and across cultures.
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.
Does biology help explain why women, on average, earn less money than men? Is there any evolutionary basis for the scarcity of female CEOs in Fortune 500 companies? According to Kingsley Browne, the answer may be yes. Biology at Work brings an evolutionary perspective to bear on issues of women in the workplace: the "glass ceiling," the "gender gap" in pay, sexual harassment, and occupational segregation. While acknowledging the role of discrimination and sexist socialization, Browne suggests that until we factor real biological differences between men and women into the equation, the explanation remains incomplete. Browne looks at behavioral differences between men and women as products of different evolutionary pressures facing them throughout human history. Womens biological investment in their offspring has led them to be on average more nurturing and risk averse, and to value relationships over competition. Men have been biologically rewarded, over human history, for displays of strength and skill, risk taking, and status acquisition. These behavioral differences have numerous workplace consequences. Not surprisingly, sex differences in the drive for status lead to sex differences in the achievement of status. Browne argues that decision makers should recognize that policies based on the assumption of a single androgynous human nature are unlikely to be successful. Simply removing barriers to inequality will not achieve equality, as women and men typically value different things in the workplace and will make different workplace choices based on their different preferences. Rather than simply putting forward the "nature" side of the debate, Browne suggests that dichotomies such as nature/nurture have impeded our understanding of the origins of human behavior. Through evolutionary biology we can understand not only how natural selection has created predispositions toward certain types of behavior but also how the social environment interacts with these predispositions to produce observed behavioral patterns.
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.
This book presents extensive field research and analysis to evaluate sexual coercion in a range of species—including all of the great apes and humans—and to clarify its role in shaping social relationships among males, among females, and between the sexes.
