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.

    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.

    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.

    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.

    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.

    This is the book that brought gender differences in ways of speaking to the forefront of public awareness. With a rare combination of scientific insight and delightful, humorous writing, Tannen shows why women and men can walk away from the same conversation with completely different impressions of what was said.Studded with lively and entertaining examples of real conversations, this book gives you the tools to understand what went wrong -- and to find a common language in which to strengthen relationships at work and at home. A classic in the field of interpersonal relations, this book will change forever the way you approach conversations.

    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.

    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.

    It opens with a question: How would an alien scientist view our species? What would it make of our sex differences, our sexual behavior, our child-rearing patterns, our moral codes, our religions, languages, and science? The book tackles these issues by drawing on ideas from two major schools of thought: evolutionary psychology and cultural evolutionary theory. The guiding assumption is that humans are animals, and that like all animals, we evolved to pass on our genes. At some point, however, we also evolved the capacity for culture - and from that moment, culture began evolving in its own right. This transformed us from a mere ape into an ape capable of reshaping the planet, travelling to other worlds, and understanding the vast universe of which we're but a tiny, fleeting fragment.

    Many of us take for granted that babies are born selfish and that it is the role of society—and especially parents—to transform them from little sociopaths into civilized beings. In Just Babies, Paul Bloom argues that humans are in fact hardwired with a sense of morality. Drawing on groundbreaking research at Yale, Bloom demonstrates that, even before they can speak or walk, babies judge the goodness and badness of others’ actions; feel empathy and compassion; act to soothe those in distress; and have a rudimentary sense of justice.Still, this innate morality is limited, sometimes tragically. We are naturally hostile to strangers, prone to parochialism and bigotry. Bringing together insights from psychology, behavioral economics, evolutionary biology, and philosophy, Bloom explores how we have come to surpass these limitations. Along the way, he examines the morality of chimpanzees, violent psychopaths, religious extremists, and Ivy League professors, and explores our often puzzling moral feelings about sex, politics, religion, and race.

    But modern times have forced the world’s tribes into a shared space, resulting in epic clashes of values along with unprecedented opportunities. As the world shrinks, the moral lines that divide us become more salient and more puzzling. We fight over everything from tax codes to gay marriage to global warming, and we wonder where, if at all, we can find our common ground. A grand synthesis of neuroscience, psychology, and philosophy, Moral Tribes reveals the underlying causes of modern conflict and lights the way forward. Greene compares the human brain to a dual-mode camera, with point-and-shoot automatic settings (“portrait,” “landscape”) as well as a manual mode. Our point-and-shoot settings are our emotions—efficient, automated programs honed by evolution, culture, and personal experience. The brain’s manual mode is its capacity for deliberate reasoning, which makes our thinking flexible. Point-and-shoot emotions make us social animals, turning Me into Us. But they also make us tribal animals, turning Us against Them. Our tribal emotions make us fight—sometimes with bombs, sometimes with words—often with life-and-death stakes. An award-winning teacher and scientist, Greene directs Harvard University’s Moral Cognition Lab, which uses cutting-edge neuroscience and cognitive techniques to understand how people really make moral decisions. Combining insights from the lab with lessons from decades of social science and centuries of philosophy, the great question of Moral Tribes is this: How can we get along with Them when what they want feels so wrong to Us? Ultimately, Greene offers a set of maxims for navigating the modern moral terrain, a practical road map for solving problems and living better lives. Moral Tribes shows us when to trust our instincts, when to reason, and how the right kind of reasoning can move us forward. A major achievement from a rising star in a new scientific field, Moral Tribes will refashion your deepest beliefs about how moral thinking works and how it can work better.

    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.

    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.

    Cacioppo’s groundbreaking research topples one of the pillars of modern medicine and psychology: the focus on the individual as the unit of inquiry. By employing brain scans, monitoring blood pressure, and analyzing immune function, he demonstrates the overpowering influence of social context—a factor so strong that it can alter DNA replication. He defines an unrecognized syndrome—chronic loneliness—brings it out of the shadow of its cousin depression, and shows how this subjective sense of social isolation uniquely disrupts our perceptions, behavior, and physiology, becoming a trap that not only reinforces isolation but can also lead to early death. He gives the lie to the Hobbesian view of human nature as a “war of all against all,” and he shows how social cooperation is, in fact, humanity’s defining characteristic. Most important, he shows how we can break the trap of isolation for our benefit both as individuals and as a society.

    So why does deception play such a prominent role in our everyday lives? In short, why do we deceive?In his bold new work, prominent biological theorist Robert Trivers unflinchingly argues that self-deception evolved in the service of deceit—the better to fool others. We do it for biological reasons—in order to help us survive and procreate. From viruses mimicking host behavior to humans misremembering (sometimes intentionally) the details of a quarrel, science has proven that the deceptive one can always outwit the masses. But we undertake this deception at our own peril.Trivers has written an ambitious investigation into the evolutionary logic of lying and the costs of leaving it unchecked.
