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 Jethá. While debunking almost everything we "know" about sex, they offer a bold alternative explanation in this provocative and brilliant book.Ryan and Jethá'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 Jethá 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.

    But in the modern world, the breast is changing. Breasts are getting bigger, arriving earlier, and attracting newfangled chemicals. Increasingly, the odds are stacked against us in the struggle with breast cancer, even among men. What makes breasts so mercurial—and so vulnerable?In this informative and highly entertaining account, intrepid science reporter Florence Williams sets out to uncover the latest scientific findings from the fields of anthropology, biology, and medicine. Her investigation follows the life cycle of the breast from puberty to pregnancy to menopause, taking her from a plastic surgeon’s office where she learns about the importance of cup size in Texas to the laboratory where she discovers the presence of environmental toxins in her own breast milk. The result is a fascinating exploration of where breasts came from, where they have ended up, and what we can do to save them.

    Heralded by Publishers Weekly as one of the best science books of the year, it is a provocative and deeply engaging book that elucidates the ties between a woman's experience of her vagina and her sense of self; her impulses, dreams, and courage; and her role in love and in society in completely new and revelatory ways sure to provoke impassioned conversation.A brilliant and nuanced synthesis of physiology, history, and cultural criticism, Vagina: A New Biography explores the physical, political, and spiritual implications of this startling series of new scientific breakthroughs for women and for society as a whole, from a writer whose conviction and keen intelligence have propelled her works to the tops of bestseller lists, and firmly into the realms of modern classics.

    Can a person think herself to orgasm? Why doesn't Viagra help women-or, for that matter, pandas? Can a dead man get an erection? Is vaginal orgasm a myth? Mary Roach shows us how and why sexual arousal and orgasm-two of the most complex, delightful, and amazing scientific phenomena on earth-can be so hard to achieve and what science is doing to make the bedroom a more satisfying place.

    According to this false-yet-familiar story, the divisions between men and women are in nature alone and not part of culture. Drawing on evolutionary science, psychology, neuroscience, endocrinology, and philosophy, Testosterone Rex disproves this ingrained myth and calls for a more equal society based on both sexes’ full human potential.

    In tracing how we ended up positioning our nondescript penis as a pulsing, awe-inspiring shaft of all masculinity and human dominance,.Emphasizing our human capacities for impulse control, Phallacy ultimately challenges the message that the penis makes the man and the man can't control himself. With instructive illustrations of unusual genitalia and tales of animal mating rituals Phallacy shows where humans fit on the continuum from fun to fatal phalli and why the human penis is an implement for intimacy, not intimidation.

    Highlighting the evolutionary functions of various physiological traits, Morris's study explores the various forms of enhancement and constraint that human societies have developed in the quest for the perfect female form. This is very much vintage Desmond Morris, delivered in his trademark voice: direct, clear, focused, and communicating what is often complex detail in simple language. In THE NAKED WOMAN, Desmond builds on his unrivalled experience as an observer of the human animal while tackling one of his most fascinating and challenging subjects to date.

    The idea of “the heterosexual” was unprecedented. After all, men and women had been having sex, marrying, building families, and sometimes even falling in love for millennia without having any special name for their emotions or acts. Yet, within half a century, “heterosexual” had become a byword for “normal,” enshrined in law, medicine, psychiatry, and the media as a new gold standard for human experience. With an eclectic scope and fascinating detail, Straight tells the eye-opening story of a complex and often contradictory man-made creation that turns out to be anything but straight or narrow.

    Whether it’s voyeurism, exhibitionism, or your run-of-the-mill foot fetish, we all possess a suite of sexual tastes as unique as our fingerprints—and as secret as the rest of the skeletons we’ve hidden in our closets.Combining cutting-edge studies and critiques of landmark research and conclusions drawn by Sigmund Freud, Alfred Kinsey, and the DSM-5, Bering pulls the curtain back on paraphilias, arguing that sexual deviance is commonplace. Bering confronts hypocrisy, prejudice, and harm as they relate to sexuality on a global scale. Humanizing so-called deviants while at the same time asking serious questions about the differences between thought and action, he presents us with a challenge: to understand that our best hope of solving some of the most troubling problems of our age hinges entirely on the amoral study of sex.

    Debra Soh uses a research-based approach to address this hot-button topic, unmasking popular misconceptions about the nature vs. nurture debate and exploring what it means to be a woman or a man in today’s society. Both scientific and objective, and drawing on original research and carefully conducted interviews, Soh tackles a wide range of issues, such as gender-neutral parenting, gender dysphoric children, and the neuroscience of being transgender. She debates today’s accepted notion that gender is a social construct and a spectrum, and challenges the idea that there is no difference between how male and female brains operate. The End of Gender is a conversation-starting work that will challenge what you thought you knew about gender, identity, and everything in between. Timely, informative, and provocative, it will arm you with the facts you need to come to your own conclusions about gender identity and its place in the world today.

    But is it? In this provocative, groundbreaking book, renowned anthropologist (and mother) Sarah Blaffer Hrdy shares a radical new vision of motherhood and its crucial role in human evolution.Hrdy strips away stereotypes and gender-biased myths to demonstrate that traditional views of maternal behavior are essentially wishful thinking codified as objective observation. As Hrdy argues, far from being "selfless," successful primate mothers have always combined nurturing with ambition, mother love with sexual love, ambivalence with devotion. In fact all mothers, in the struggle to guarantee both their own survival and that of their offspring, deal nimbly with competing demands and conflicting strategies.In her nuanced, stunningly original interpretation of the relationships between mothers and fathers, mothers and babies, and mothers and their social groups, Hrdy offers not only a revolutionary new meaning to motherhood but an important new understanding of human evolution. Written with grace and clarity, suffused with the wisdom of a long and distinguished career, Mother Nature is a profound contribution to our understanding of who we are as a species--and why we have become this way.

    On its first publication in 1972 it sparked an international debate and became a rallying-point for feminism, changing the terminology of anthropologists forever. Starting with her demolition of the Biblical myth that woman was an afterthought to the creation of man, Elaine Morgan rewrites human history and evolution.This lively, informative book sets out to solve the riddle of our origins; its answer is controversial. Elaine Morgan has made The Aquatic Ape Hypothesis a plausible alternative to conventional theories of evolution and The Descent of Woman first set out an understanding of who humans are and where they came from.Elaine Morgan was best known as a writer for television until the publication of The Descent of Woman in 1972, which became an international bestseller. She then spent ten years researching human evolution before publishing The Aquatic Ape (published by Souvenir Press as a revised edition, The Aquatic Ape Hypothesis) in 1982. In the years since, The Aquatic Ape Hypothesis has gone on to win widespread support among scientists.It is a measure of Elaine Morgan's enduring importance, provocative thought and international reputation that in January 2006, the first Chinese translation of The Aquatic Ape Hypothesis became a Number 1 bestseller in Taiwan.

    Based on the most massive study of human mating ever undertaken, encompassing more than 10,000 people of all ages from thirty-seven cultures worldwide, The Evolution of Desire is the first book to present a unified theory of human mating behavior.Now in an updated edition with two new chapters by the author, The Evolution of Desire presents the latest research in the field, including starting new discoveries about the evolutionary advantages of infidelity, orgasm, and physical attractiveness.

    Jonathan Eig's masterful narrative revolves around four principal characters: the fiery feminist Margaret Sanger, who was a champion of birth control in her campaign for the rights of women but neglected her own children in pursuit of free love; the beautiful Katharine McCormick, who owed her fortune to her wealthy husband, the son of the founder of International Harvester and a schizophrenic; the visionary scientist Gregory Pincus, who was dismissed by Harvard in the 1930s as a result of his experimentation with in vitro fertilization but who, after he was approached by Sanger and McCormick, grew obsessed with the idea of inventing a drug that could stop ovulation; and the telegenic John Rock, a Catholic doctor from Boston who battled his own church to become an enormously effective advocate in the effort to win public approval for the drug that would be marketed by Searle as Enovid.Spanning the years from Sanger’s heady Greenwich Village days in the early twentieth century to trial tests in Puerto Rico in the 1950s to the cusp of the sexual revolution in the 1960s, this is a grand story of radical feminist politics, scientific ingenuity, establishment opposition, and, ultimately, a sea change in social attitudes. Brilliantly researched and briskly written, The Birth of the Pill is gripping social, cultural, and scientific history.

    Angier takes readers on a mesmerizing tour of female anatomy and physiology that explores everything from organs to orgasm, and delves into topics such as exercise, menopause, and the mysterious properties of breast milk.A self-proclaimed "scientific fantasia of womanhood." Woman ultimately challenges widely accepted Darwinian-based gender stereotypes. Angier shows how cultural biases have influenced research in evolutionary psychology (the study of the biological bases of behavior) and consequently led to dubious conclusions about "female nature." such as the idea that women are innately monogamous while men are natural philanderers.But Angier doesn't just point fingers; she offers optimistic alternatives and transcends feminist polemics with an enlightened subversiveness that makes for a joyful, fresh vision of womanhood. Woman is a seminal work that will endure as an essential read for anyone intersted in how biology affects who we are as women, as men, and as human beings.
