Since Darwin's day, we've been told that sexual monogamy comes naturally to our species. Mainstream science—as well as religious and cultural institutions—has maintained that men and women evolved in families in which a man's possessions and protection were exchanged for a woman's fertility and fidelity. But this narrative is collapsing. Fewer and fewer couples are getting married, and divorce rates keep climbing as adultery and flagging libido drag down even seemingly solid marriages. How can reality be reconciled with the accepted narrative? It can't be, according to renegade thinkers Christopher Ryan and Cacilda Jethå. While debunking almost everything we "know" about sex, they offer a bold alternative explanation in this provocative and brilliant book. Ryan and Jethå's central contention is that human beings evolved in egalitarian groups that shared food, child care, and, often, sexual partners. Weaving together convergent, frequently overlooked evidence from anthropology, archaeology, primatology, anatomy, and psychosexuality, the authors show how far from human nature monogamy really is. Human beings everywhere and in every era have confronted the same familiar, intimate situations in surprisingly different ways. The authors expose the ancient roots of human sexuality while pointing toward a more optimistic future illuminated by our innate capacities for love, cooperation, and generosity. With intelligence, humor, and wonder, Ryan and Jethå show how our promiscuous past haunts our struggles over monogamy, sexual orientation, and family dynamics. They explore why long-term fidelity can be so difficult for so many; why sexual passion tends to fade even as love deepens; why many middle-aged men risk everything for transient affairs with younger women; why homosexuality persists in the face of standard evolutionary logic; and what the human body reveals about the prehistoric origins of modern sexuality. In the tradition of the best historical and scientific writing, Sex at Dawn unapologetically upends unwarranted assumptions and unfounded conclusions while offering a revolutionary understanding of why we live and love as we do.

It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.

Why we are so fascinated with sex and sexuality—from the preeminent philosopher of the 20th century. Michel Foucault offers an iconoclastic exploration of why we feel compelled to continually analyze and discuss sex, and of the social and mental mechanisms of power that cause us to direct the questions of what we are to what our sexuality is.

“[A] deliciously written account of the evolution of sex, in all of its bizarre manifestations” by a noted paleontologist—"Read, blush, and enjoy!” (Jared Diamond, author of Guns, Germs, and Steel). We all know about the birds and the bees, but what about the ancient placoderm fishes and the dinosaurs? In 2008, paleontologist John A. Long and a team of researchers announced their discovery of a 380-million-year-old placoderm fish fossil, known as “the mother fish,” which revealed the earliest known example of internal fertilization. As a result, placoderms are now considered to be the first species to have had intimate sexual reproduction, or sex as we know it—sort of. Inspired by this incredible find, Long began a quest to uncover the evolutionary history of copulation and insemination. In The Dawn of the Deed, he takes readers on a lively tour through the sex lives of ancient fish and the unusual mating habits of arthropods, tortoises, and even a well-endowed Argentine Duck. Long discusses these discoveries alongside what we know about reproductive biology and evolutionary theory, using the fossil record to provide a provocative account of prehistoric sex. The Dawn of the Deed also explores fascinating revelations about animal reproduction, from homosexual penguins to monogamous seahorses to the difficulties of dinosaur romance.

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 seasoned woman is spicy. She has been marinated in life experience. . . . She can be alternately sweet, tart, bubbly, mellow. She can be maternal and playful. Bossy and submissive. Strong and soft. . . . The seasoned woman knows who she is. She could be any one of us, as long as she is committed to living fully and passionately in the second half of life. In her most groundbreaking work since Passages and The Silent Passage, bestselling author Gail Sheehy reveals a hidden cultural phenomenon–increased vitality in women’s sex and love lives after fifty. Sex and the Seasoned Woman is the story of an intimate revolution taking place under our very noses. Boomer generation women in midlife are open to sex, love, dating, new dreams, exploring spirituality, and revitalizing their marriages as never before. This is a new universe of passionate, liberated women–married and single–who are unwilling to settle for the stereotypical roles of middle age and are now realizing they don’t have to. As life spans grow longer and as societal constraints continue to loosen, older women–once free of the exhausting demands of young children, needy husbands, and demanding careers–find themselves ready to pursue the passionate life. They embrace their “second adulthood” as a period of reawakening. Written in Sheehy’s singularly compelling style, combining interviews and research, this book gives voice to more than a hundred fascinating and colorful women. The inspiring stories tell of wives who reinvigorate their marriages after their children leave the nest as well as divorced, widowed, and long-single women who find new dreams and new loves. Sheehy delineates a crucial link between cultivating a new dream and reopening the pathway to intimacy and sexual pleasure. She also examines the latest medical breakthroughs addressing symptoms that have unnecessarily curtailed women’s sex lives. From women who find their sexuality reawakened by a younger lover, to couples whose marriages survive health crises and grow stronger, to women who finally find a soulmate in their sixties, to stories from seasoned sirens in their seventies, eighties, and even nineties, these portraits cover an enormous range of experience. In them, Sheehy locates the universal patterns that enable us all to recognize and understand our own lives.

Punctuated with remarkable case studies, this book explores extraordinary encounters between hermaphrodites--people born with "ambiguous" sexual anatomy--and the medical and scientific professionals who grappled with them. Alice Dreger focuses on events in France and Britain in the late nineteenth century, a moment of great tension for questions of sex roles. While feminists, homosexuals, and anthropological explorers openly questioned the natures and purposes of the two sexes, anatomical hermaphrodites suggested a deeper question: just how many human sexes are there? Ultimately hermaphrodites led doctors and scientists to another surprisingly difficult question: what is sex, really? Hermaphrodites and the Medical Invention of Sex takes us inside the doctors' chambers to see how and why medical and scientific men constructed sex, gender, and sexuality as they did, and especially how the material conformation of hermaphroditic bodies--when combined with social exigencies--forced peculiar constructions. Throughout the book Dreger indicates how this history can help us to understand present-day conceptualizations of sex, gender, and sexuality. This leads to an epilogue, where the author discusses and questions the protocols employed today in the treatment of intersexuals (people born hermaphroditic). Given the history she has recounted, should these protocols be reconsidered and revised? A meticulously researched account of a fascinating problem in the history of medicine, this book will compel the attention of historians, physicians, medical ethicists, intersexuals themselves, and anyone interested in the meanings and foundations of sexual identity.
