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.

    Since then, Fisher has conducted pioneering brain research on lust, romantic love, and attachment; gathered data on more than 80,000 people to explain why you love who you love; and collected information on more than 30,000 men and women on sexting, hooking up, friends with benefits, and other current trends in courtship and marriage. And she presents a new, scientifically based and optimistic perspective on relationships in our digital age—what she calls “slow love.”This is a cutting-edge tour de force that traces human family life from its origins in Africa over 20 million years ago to the Internet dating sites and bedrooms of today. And it’s got it all: the copulatory gaze and other natural courting ploys; the who, when, where, and why of adultery; love addictions; her discovery of four broad chemically based personality styles and what each seeks in romance; the newest data on worldwide (biologically based) patterns of divorce; how and why men and women think differently; the real story of women, men, and power; the rise—and fall—of the sexual double standard; and what brain science tells us about how to make and keep a happy partnership.

    Here is a delightfully entertaining and enlightening look at the unique sex lives of humans.

    Here, in an enlightening and entertaining cultural study, is a book that puts into context the central role of the penis within Western civilization. Deified by ancient pagan cultures and demonized by the early Roman church, the penis was later secularized by pioneering anatomists such as Leonardo da Vinci. After being measured 'scientifically' in an effort to subjugate some races while elevating others, the organ was psychoanalysed by Sigmund Freud. Now, after being politicized by feminism and exploited in countless ways by pop culture, Friedman shows how the arrival of erection industry products such as Viagra is more than a health or business story. It is the latest chapter in one of the longest sagas in human history: the story of man's relationship with his penis.

     For his groundbreaking sexual research, Alfred Kinsey and his team interviewed 18,000 people, relying on them to honestly report their most intimate experiences. Using the Internet, the neuroscientists Ogas and Gaddam quietly observed the raw sexual behaviors of half a billion people. By combining their observations with neuroscience and animal research, these two young neuroscientists finally answer the long-disputed question: what do people really like? Ogas and Gaddam's findings are transforming the way scientists and therapists think about sexual desire. In their startling book, Ogas and Gaddam analyze a "billion wicked thoughts" on the Internet: a billion Web searches, a million individual search histories, a million erotic stories, a half-million erotic videos, a million Web sites, millions of online personal ads, and many other enormous sources of sexual data in order to understand the true differences between male and female desires, including: ?Men and women have hardwired sexual cues analogous to our hardwired tastes-there are sexual versions of sweet, sour, salty, savory, and bitter. But men and women are wired with different sets of cues. ?The male sexual brain resembles a reckless hunter, while the female sexual brain resembles a cautious detective agency. ?Men form their sexual interests during adolescence and rarely change. Women's sexual interests are plastic and change frequently. ?The male sexual brain is an "or gate": A single stimulus can arouse it. The female sexual brain is an "and gate": It requires many simultaneous stimuli to arouse it. ?When it comes to sexual arousal, men prefer overweight women to underweight women, and a significant number of men seek out erotic images of women in their 40s, 50s, and 60s. ?Women enjoy writing and sharing erotic stories with other women. The fastest growing genre of erotic stories for women are stories about two heterosexual men having sex. ?Though the male sexual brain is much more different from the female sexual brain than is commonly believed, the sexual brain of gay men is virtually identical to that of straight men. Featuring cutting-edge, jaw-dropping science, this wildly entertaining and controversial book helps readers understand their partner's sexual desires with a depth of knowledge unavailable from any other source. Its fascinating and occasionally disturbing findings will rock our modern understanding of sexuality, just as Kinsey's reports did sixty years ago.

    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.

    Etcoff, a faculty member at Harvard Medical School and a practicing psychologist at Massachusetts General Hospital, skewers the enduring myth that the pursuit of beauty is a learned behavior.Etcoff puts forth that beauty is neither a cultural construction, an invention of the fashion industry, nor a backlash against feminism, but instead is in our biology. It's an essential and ineradicable part of human nature that is revered and ferociously pursued in nearly every civilizatoin--and for good reason. Those features to which we are most attracted are often signals of fertility and fecundity. When seen in the context of a Darwinian struggle for survival, our sometimes extreme attempts to attain beauty--both to become beautiful ourselves and to acquire an attractive partner--become understandable. Moreover, if we come to understand how the desire for beauty is innate, then we can begin to work in our interests, and not soley for the interests of our genetic tendencies.

    Psychologist Geoffrey Miller offers the most convincing-and radical-explanation for how and why the human mind evolved.Consciousness, morality, creativity, language, and art: these are the traits that make us human. Scientists have traditionally explained these qualities as merely a side effect of surplus brain size, but Miller argues that they were sexual attractors, not side effects. He bases his argument on Darwin's theory of sexual selection, which until now has played second fiddle to Darwin's theory of natural selection, and draws on ideas and research from a wide range of fields, including psychology, economics, history, and pop culture. Witty, powerfully argued, and continually thought-provoking, The Mating Mind is a landmark in our understanding of our own species.

    All that mystery, all that poetry, all those complex behaviors sur­rounding human bonding leading to the most life-changing decisions we’ll ever make, are unconsciously driven by a few molecules in our brain. How does love begin? How can two strangers come to the conclusion that it would not only be pleasant to share their lives, but that they must share them? How can a man say he loves his wife, yet still cheat on her? Why do others stay in relationships even after the ro­mance fades? How is it possible to fall in love with the “wrong” person? How do people come to have a “type”? Physical attraction, jealousy, infidelity, mother-infant bonding—all the behaviors that so often leave us befuddled—are now being teased out of the fog of mystery thanks to today’s social neuroscience. Larry Young, one of the world’s leading experts in the field, and journalist Brian Alexander explain how those findings apply to you. Drawing on real human stories and research from labs around the world, The Chemistry Between Us is a bold attempt to create a “grand unified theory” of love. Some of the mind-blowing insights include:Love can get such a grip on us because it is, literally, an addiction. To a woman falling in love, a man is like her baby. Why it’s false to say society makes gender, and how it’s possible to have the body of one gender and the brain of another.Why some people are more likely to cheat than others. Why we sometimes truly can’t resist temptation.  Young and Alexander place their revelations into historical, political, and social contexts. In the pro­cess, they touch on everything from gay marriage to why single-mother households might not be good for society. The Chemistry Between Us offers powerful in­sights into love, sex, gender, sexual orientation, and family life that will prove to be enlightening, contro­versial, and thought provoking.

    The Red Queen answers dozens of other riddles of human nature and culture -- including why men propose marriage, the method behind our maddening notions of beauty, and the disquieting fact that a woman is more likely to conceive a child by an adulterous lover than by her husband. Brilliantly written, The Red Queen offers an extraordinary new way of interpreting the human condition and how it has evolved.

    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.

    Now the new book More Than Two can help you find your own way. With completely new material and a fresh approach, Franklin Veaux and Eve Rickert wrote More Than Two to expand on and update the themes and ideas in the wildly popular polyamory website morethantwo.com.From partners, authors and practicing polyamorists Franklin Veaux and Eve Rickert comes the long-awaited, wide-ranging resource exploring the often-complex world of living polyamorously. Highlighting the nuances (no, this isn’t swinging), the relationship options (do you suit a V, an N, an open network?), the myths (don’t count on wild orgies and endless sex—but don’t rule them out, either!) and the expectations (communication, transparency and trust are paramount), the authors share not only their hard-won philosophies about polyamory, but also their hurts and embarrassments. More Than Two is entirely without judgment and peppered with a good dose of humor. Franklin and Eve underscore the importance of engaging in ethical polyamory, while gently guiding readers through the thorny issues of jealousy and insecurity. And no, they’re not trying to convert you: they know that polyamory isn’t for everyone. Franklin and Eve simply provide those who might be embarking on this lifestyle, or those who have already begun, with a toolkit to help them make informed decisions and set them on a path to enjoying multiple happy, strong, enriching relationships. More Than Two is the book the polyamory community has been waiting for. And who knows? It may just be the book you didn’t even know you were waiting for.

    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 ways of thinking about very old matters."A masterpiece of ideas and a unique contribution to our understanding of gender and history, sexuality and evolution." -- Jean Houston[Note: includes Reader's Guide]

    But the same things that have made it so have also made a good marriage more fulfilling than ever before. In this enlightening and hugely entertaining book, historian and marriage expert Stephanie Coontz takes readers from the marital intrigues of ancient Babylon to the sexual torments of Victorian couples to demonstrate how recent the idea of marrying for love is-and how absurd it would have seemed to most of our ancestors. It was only 200 years ago that marriage began to be about love and emotional commitment, and since then the very things that have strengthened marriage as a personal relationship have steadily weakened it as a social institution. Marriage, A History brings intelligence, wit, and some badly needed perspective to today's marital debates and dilemmas.

    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.
