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.

    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.

     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.

    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.

    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.

    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.

    He shows how many intellectuals have denied the existence of human nature by embracing three linked dogmas: the Blank Slate (the mind has no innate traits), the Noble Savage (people are born good and corrupted by society), and the Ghost in the Machine (each of us has a soul that makes choices free from biology). Each dogma carries a moral burden, so their defenders have engaged in desperate tactics to discredit the scientists who are now challenging them.Pinker injects calm and rationality into these debates by showing that equality, progress, responsibility, and purpose have nothing to fear from discoveries about a rich human nature. He disarms even the most menacing threats with clear thinking, common sense, and pertinent facts from science and history.Despite its popularity among intellectuals during much of the twentieth century, he argues, the doctrine of the Blank Slate may have done more harm than good. It denies our common humanity and our individual preferences, replaces hardheaded analyses of social problems with feel-good slogans, and distorts our understanding of government, violence, parenting, and the arts.Pinker shows that an acknowledgement of human nature that is grounded in science and common sense, far from being dangerous, can complement insights about the human condition made by millennia of artists and philosophers. All this is done in the style that earned his previous books many prizes and worldwide acclaim: wit, lucidity, and insight into matters great and small.

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

    Women crave intimacy and emotional connection. Women don't want sex with strangers. Right? Wrong. Could 'the fairer sex' in fact be more sexually aggressive and anarchic than men? In What Do Women Want? Adventures in the Science of Female Desire, critically acclaimed journalist Daniel Bergner looks at the evidence. Recent research, he finds, dismantles the myths to reveal an unprecedented portrait of female lust- the triggers, the fantasies, the mind-body connection (and disconnection), the reasons behind the loss of libido and, most revelatory, that this loss is not inevitable.

    Even though the glass ceiling is cracked, most women stay comfortably beneath it, and everywhere we hear about vitally important “hardwired” differences between male and female brains. The neuroscience we read about in magazines, newspaper articles, books, and sometimes even scientific journals increasingly tells a tale of two brains, and the result is more often than not a validation of the status quo. Women, it seems, are just too intuitive for math, men too focused for housework.Drawing on the latest research in neuroscience and psychology, Cordelia Fine debunks the myth of hardwired differences between men’s and women’s brains, unraveling the evidence behind such claims as men’s brains aren’t wired for empathy, and women’s brains aren’t made to fix cars. She then goes one step further, offering a very different explanation of the dissimilarities between men’s and women’s behavior. Instead of a “male brain” and a “female brain,” Fine gives us a glimpse of plastic, mutable minds that are continuously influenced by cultural assumptions about gender.Delusions of Gender provides us with a much-needed corrective to the belief that men’s and women’s brains are intrinsically different--a belief that, as Fine shows with insight and humor--all too often works to the detriment of ourselves and our society.

    It also had an unexpected effect on its author: Orenstein realized that talking about girls is only half the conversation. Boys are subject to the same cultural forces as girls—steeped in the same distorted media images and binary stereotypes of female sexiness and toxic masculinity—which equally affect how they navigate sexual and emotional relationships. In Boys & Sex, Peggy Orenstein dives back into the lives of young people to once again give voice to the unspoken, revealing how young men understand and negotiate the new rules of physical and emotional intimacy.Drawing on comprehensive interviews with young men, psychologists, academics, and experts in the field, Boys & Sex dissects so-called locker room talk; how the word “hilarious” robs boys of empathy; pornography as the new sex education; boys’ understanding of hookup culture and consent; and their experience as both victims and perpetrators of sexual violence. By surfacing young men’s experience in all its complexity, Orenstein is able to unravel the hidden truths, hard lessons, and important realities of young male sexuality in today’s world. The result is a provocative and paradigm-shifting work that offers a much-needed vision of how boys can truly move forward as better men.

    Sapolsky's storytelling concept is delightful but it also has a powerful intrinsic logic: he starts by looking at the factors that bear on a person's reaction in the precise moment a behavior occurs, and then hops back in time from there, in stages, ultimately ending up at the deep history of our species and its evolutionary legacy.And so the first category of explanation is the neurobiological one. A behavior occurs--whether an example of humans at our best, worst, or somewhere in between. What went on in a person's brain a second before the behavior happened? Then Sapolsky pulls out to a slightly larger field of vision, a little earlier in time: What sight, sound, or smell caused the nervous system to produce that behavior? And then, what hormones acted hours to days earlier to change how responsive that individual is to the stimuli that triggered the nervous system? By now he has increased our field of vision so that we are thinking about neurobiology and the sensory world of our environment and endocrinology in trying to explain what happened.Sapolsky keeps going: How was that behavior influenced by structural changes in the nervous system over the preceding months, by that person's adolescence, childhood, fetal life, and then back to his or her genetic makeup? Finally, he expands the view to encompass factors larger than one individual. How did culture shape that individual's group, what ecological factors millennia old formed that culture? And on and on, back to evolutionary factors millions of years old.The result is one of the most dazzling tours d'horizon of the science of human behavior ever attempted, a majestic synthesis that harvests cutting-edge research across a range of disciplines to provide a subtle and nuanced perspective on why we ultimately do the things we do...for good and for ill. Sapolsky builds on this understanding to wrestle with some of our deepest and thorniest questions relating to tribalism and xenophobia, hierarchy and competition, morality and free will, and war and peace. Wise, humane, often very funny, Behave is a towering achievement, powerfully humanizing, and downright heroic in its own right.

    But natural selection has given us a suite of beneficial social features, including our capacity for love, friendship, cooperation, and learning. Beneath all of our inventions -- our tools, farms, machines, cities, nations -- we carry with us innate proclivities to make a good society.In Blueprint, Nicholas A. Christakis introduces the compelling idea that our genes affect not only our bodies and behaviors, but also the ways in which we make societies, ones that are surprisingly similar worldwide.With many vivid examples -- including diverse historical and contemporary cultures, communities formed in the wake of shipwrecks, commune dwellers seeking utopia, online groups thrown together by design or involving artificially intelligent bots, and even the tender and complex social arrangements of elephants and dolphins that so resemble our own -- Christakis shows that, despite a human history replete with violence, we cannot escape our social blueprint for goodness.In a world of increasing political and economic polarization, it's tempting to ignore the positive role of our evolutionary past. But by exploring the ancient roots of goodness in civilization, Blueprint shows that our genes have shaped societies for our welfare and that, in a feedback loop stretching back many thousands of years, societies are still shaping our genes today.

    Wright unveils the genetic strategies behind everything from our sexual preferences to our office politics--as well as their implications for our moral codes and public policies. Illustrations.

    This may seem hard to accept, but, as Harari explains in his trademark style—thorough, yet riveting—famine, plague and war have been transformed from incomprehensible and uncontrollable forces of nature into manageable challenges. For the first time ever, more people die from eating too much than from eating too little; more people die from old age than from infectious diseases; and more people commit suicide than are killed by soldiers, terrorists and criminals put together. The average American is a thousand times more likely to die from binging at McDonalds than from being blown up by Al Qaeda.What then will replace famine, plague, and war at the top of the human agenda? As the self-made gods of planet earth, what destinies will we set ourselves, and which quests will we undertake? Homo Deus explores the projects, dreams and nightmares that will shape the twenty-first century—from overcoming death to creating artificial life. It asks the fundamental questions: Where do we go from here? And how will we protect this fragile world from our own destructive powers? This is the next stage of evolution. This is Homo Deus.With the same insight and clarity that made Sapiens an international hit and a New York Times bestseller, Harari maps out our future.
