Contrary to what the glossy magazines would have us believe, we do not enjoy potato chips because they crunch just like the insects our forebears snacked on. As Zuk argues, such beliefs incorrectly assume that we’re stuck—finished evolving—and have been for tens of thousands of years. She draws on fascinating evidence that examines everything from adults’ ability to drink milk to the texture of our ear wax to show that we’ve actually never stopped evolving. Our nostalgic visions of an ideal evolutionary past in which we ate, lived, and reproduced as we were “meant to” fail to recognize that we were never perfectly suited to our environment. Evolution is about change, and every organism is full of trade-offs.From debunking the caveman diet to unraveling gender stereotypes, Zuk gives an analysis of widespread paleofantasies and the scientific evidence that undermines them, all the while broadening our understanding of our origins and what they can really tell us about our present and our future.

    With his classic Why We Get Sick, Dr. Randolph Nesse helped to establish the field of evolutionary medicine. Now he returns with a book that transforms our understanding of mental disorders by exploring a fundamentally new question. Instead of asking why certain people suffer from mental illness, Nesse asks why natural selection has left us all with fragile minds.Drawing on revealing stories from his own clinical practice and insights from evolutionary biology, Nesse shows how negative emotions are useful in certain situations, yet can become overwhelming. Anxiety protects us from harm in the face of danger, but false alarms are inevitable. Low moods prevent us from wasting effort in pursuit of unreachable goals, but they often escalate into pathological depression. Other mental disorders, such as addiction and anorexia, result from the mismatch between modern environment and our ancient human past. And there are good evolutionary reasons for sexual disorders and for why genes for schizophrenia persist. Taken together, these and many more insights help to explain the pervasiveness of human suffering, and show us new paths for relieving it by understanding individuals as individuals.

    What occurred during human evolution to account for this paradox? What are the two kinds of aggression that primates are prone to, and why did each evolve separately? How does the intensity of violence among humans compare with the aggressive behavior of other primates? How did humans domesticate themselves? And how were the acquisition of language and the practice of capital punishment determining factors in the rise of culture and civilization?Authoritative, provocative, and engaging, The Goodness Paradox offers a startlingly original theory of how, in the last 250 million years, humankind became an increasingly peaceful species in daily interactions even as its capacity for coolly planned and devastating violence remains undiminished. In tracing the evolutionary histories of reactive and proactive aggression, biological anthropologist Richard Wrangham forcefully and persuasively argues for the necessity of social tolerance and the control of savage divisiveness still haunting us today.

    Moral behavior does not begin and end with religion but is in fact a product of evolution.For many years, de Waal has observed chimpanzees soothe distressed neighbors and bonobos share their food. Now he delivers fascinating fresh evidence for the seeds of ethical behavior in primate societies that further cements the case for the biological origins of human fairness. Interweaving vivid tales from the animal kingdom with thoughtful philosophical analysis, de Waal seeks a bottom-up explanation of morality that emphasizes our connection with animals. In doing so, de Waal explores for the first time the implications of his work for our understanding of modern religion. Whatever the role of religious moral imperatives, he sees it as a “Johnny-come-lately” role that emerged only as an addition to our natural instincts for cooperation and empathy.But unlike the dogmatic neo-atheist of his book’s title, de Waal does not scorn religion per se. Instead, he draws on the long tradition of humanism exemplified by the painter Hieronymus Bosch and asks reflective readers to consider these issues from a positive perspective: What role, if any, does religion play for a well-functioning society today? And where can believers and nonbelievers alike find the inspiration to lead a good life?Rich with cultural references and anecdotes of primate behavior, The Bonobo and the Atheist engagingly builds a unique argument grounded in evolutionary biology and moral philosophy. Ever a pioneering thinker, de Waal delivers a heartening and inclusive new perspective on human nature and our struggle to find purpose in our lives.

    It's an evolutionary riddle that at long last makes sense in this intriguing book about what gossip has done for our talkative species. Psychologist Robin Dunbar looks at gossip as an instrument of social order and cohesion--much like the endless grooming with which our primate cousins tend to their social relationships.Apes and monkeys, humanity's closest kin, differ from other animals in the intensity of these relationships. All their grooming is not so much about hygiene as it is about cementing bonds, making friends, and influencing fellow primates. But for early humans, grooming as a way to social success posed a problem: given their large social groups of 150 or so, our earliest ancestors would have had to spend almost half their time grooming one another--an impossible burden. What Dunbar suggests--and his research, whether in the realm of primatology or in that of gossip, confirms--is that humans developed language to serve the same purpose, but far more efficiently. It seems there is nothing idle about chatter, which holds together a diverse, dynamic group--whether of hunter-gatherers, soldiers, or workmates.Anthropologists have long assumed that language developed in relationships among males during activities such as hunting. Dunbar's original and extremely interesting studies suggest otherwise: that language in fact evolved in response to our need to keep up to date with friends and family. We needed conversation to stay in touch, and we still need it in ways that will not be satisfied by teleconferencing, email, or any other communication technology. As Dunbar shows, the impersonal world of cyberspace will not fulfill our primordial need for face-to-face contact.From the nit-picking of chimpanzees to our chats at coffee break, from neuroscience to paleoanthropology, Grooming, Gossip, and the Evolution of Language offers a provocative view of what makes us human, what holds us together, and what sets us apart.

    He argues that humans have evolved a universal moral instinct, unconsciously propelling us to deliver judgments of right and wrong independent of gender, education, and religion. Experience tunes up our moral actions, guiding what we do as opposed to how we deliver our moral verdicts.For hundreds of years, scholars have argued that moral judgments arise from rational and voluntary deliberations about what ought to be. The common belief today is that we reach moral decisions by consciously reasoning from principled explanations of what society determines is right or wrong. This perspective has generated the further belief that our moral psychology is founded entirely on experience and education, developing slowly and subject to considerable variation across cultures. In his groundbreaking book, Hauser shows that this dominant view is illusory.Combining his own cutting-edge research with findings in cognitive psychology, linguistics, neuroscience, evolutionary biology, economics, and anthropology, he examines the implications of his theory for issues of bioethics, religion, law, and our everyday lives.

    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.

    Yet there’s a black hole at the heart of biology. We do not know why complex life is the way it is, or, for that matter, how life first began. In The Vital Question, award-winning author and biochemist Nick Lane radically reframes evolutionary history, putting forward a solution to conundrums that have puzzled generations of scientists.For two and a half billion years, from the very origins of life, single-celled organisms such as bacteria evolved without changing their basic form. Then, on just one occasion in four billion years, they made the jump to complexity. All complex life, from mushrooms to man, shares puzzling features, such as sex, which are unknown in bacteria. How and why did this radical transformation happen?The answer, Lane argues, lies in energy: all life on Earth lives off a voltage with the strength of a lightning bolt. Building on the pillars of evolutionary theory, Lane’s hypothesis draws on cutting-edge research into the link between energy and cell biology, in order to deliver a compelling account of evolution from the very origins of life to the emergence of multicellular organisms, while offering deep insights into our own lives and deaths.Both rigorous and enchanting, The Vital Question provides a solution to life’s vital question: why are we as we are, and indeed, why are we here at all?

    This book engaged some of the hardest questions in the evolution debate, and it showed the ever-cautious Darwin at his boldest. If Darwin had one goal with Expression , it was to demonstrate the power of his theories for explaining the origin of our most cherished human qualities: morality and intellect. As Darwin explained, "He who admits, on general grounds, that the structure and habits of all animals have been gradually evolved, will look at the whole subject of Expression in a new and interesting light."

    While we are similar to other mammals in many ways, our behavior sets us apart. Our unparalleled ability to adapt has allowed us to occupy virtually every habitat on earth using an incredible variety of tools and subsistence techniques. Our societies are larger, more complex, and more cooperative than any other mammal's. In this stunning exploration of human adaptation, Peter J. Richerson and Robert Boyd argue that only a Darwinian theory of cultural evolution can explain these unique characteristics.Not by Genes Alone offers a radical interpretation of human evolution, arguing that our ecological dominance and our singular social systems stem from a psychology uniquely adapted to create complex culture. Richerson and Boyd illustrate here that culture is neither superorganic nor the handmaiden of the genes. Rather, it is essential to human adaptation, as much a part of human biology as bipedal locomotion. Drawing on work in the fields of anthropology, political science, sociology, and economics—and building their case with such fascinating examples as kayaks, corporations, clever knots, and yams that require twelve men to carry them—Richerson and Boyd convincingly demonstrate that culture and biology are inextricably linked, and they show us how to think about their interaction in a way that yields a richer understanding of human nature.In abandoning the nature-versus-nurture debate as fundamentally misconceived, Not by Genes Alone is a truly original and groundbreaking theory of the role of culture in evolution and a book to be reckoned with for generations to come. “I continue to be surprised by the number of educated people (many of them biologists) who think that offering explanations for human behavior in terms of culture somehow disproves the suggestion that human behavior can be explained in Darwinian evolutionary terms. Fortunately, we now have a book to which they may be directed for enlightenment . . . . It is a book full of good sense and the kinds of intellectual rigor and clarity of writing that we have come to expect from the Boyd/Richerson stable.”—Robin Dunbar, Nature “Not by Genes Alone is a valuable and very readable synthesis of a still embryonic but very important subject straddling the sciences and humanities.”—E. O. Wilson, Harvard University

    Why don't facts work? Why, that is, did the obviously intelligent man beside him sincerely believe in Adam and Eve, the Garden of Eden and a six-thousand-year-old Earth, in spite of the evidence against them? It was the start of a journey that would lead Storr all over the world--from Texas to Warsaw to the Outer Hebrides--meeting an extraordinary cast of modern heretics whom he tries his best to understand. He goes on a tour of Holocaust sites with David Irving and a band of neo-Nazis; experiences his own murder during past-life regression hypnosis; discusses the looming One World Government with iconic climate skeptic Lord Monckton; and investigates the tragic life and death of a woman who believed her parents were high priests in a baby-eating cult. Using a unique mix of highly personal memoir, investigative journalism, and the latest research from neuroscience and experimental psychology, Storr reveals how the stories we tell ourselves about the world invisibly shape our beliefs, and how the neurological "hero maker" inside us all can so easily lead to self-deception, toxic partisanship, and science denial.

    Their struggle to survive on the open grasslands required a shift from individualism to a new form of collectivism, which forever altered the way our mind works. It changed the way we fight and our proclivity to make peace, it changed the way we lead and the way we follow, it made us innovative but not inventive, it created a new kind of social intelligence, and it led to new sources of life satisfaction.In The Social Leap, William von Hippel lays out this revolutionary hypothesis, tracing human development through three critical evolutionary inflection points to explain how events in our distant past shape our lives today. From the mundane, such as why we exaggerate, to the surprising, such as why we believe our own lies and why fame and fortune are as likely to bring misery as happiness, the implications are far reaching and extraordinary.Blending anthropology, biology, history, and psychology with evolutionary science, The Social Leap is a fresh and provocative look at our species that provides new clues about who we are, what makes us happy, and how to use this knowledge to improve our lives.

    New findings in molecular biology challenge the gene-centered version of Darwinian theory according to which adaptation occurs only through natural selection of chance DNA variations. In Evolution in Four Dimensions, Eva Jablonka and Marion Lamb argue that there is more to heredity than genes. They trace four dimensions in evolution -- four inheritance systems that play a role in evolution: genetic, epigenetic (or non-DNA cellular transmission of traits), behavioral, and symbolic (transmission through language and other forms of symbolic communication). These systems, they argue, can all provide variations on which natural selection can act. Evolution in Four Dimensions offers a richer, more complex view of evolution than the gene-based, one-dimensional view held by many today. The new synthesis advanced by Jablonka and Lamb makes clear that induced and acquired changes also play a role in evolution. After discussing each of the four inheritance systems in detail, Jablonka and Lamb put Humpty Dumpty together again by showing how all of these systems interact. They consider how each may have originated and guided evolutionary history and they discuss the social and philosophical implications of the four-dimensional view of evolution. Each chapter ends with a dialogue in which the authors engage the contrarieties of the fictional (and skeptical) I.M., or Ifcha Mistabra -- Aramaic for the opposite conjecture -- refining their arguments against I.M.'s vigorous counterarguments. The lucid and accessible text is accompanied by artist-physician Anna Zeligowski's lively drawings, which humorously and effectively illustrate the authors' points.

    If reason is so useful, why didn't it also evolve in other animals? If reason is that reliable, why do we produce so much thoroughly reasoned nonsense? In their groundbreaking account of the evolution and workings of reason, Hugo Mercier and Dan Sperber set out to solve this double enigma. Reason, they argue with a compelling mix of real-life and experimental evidence, is not geared to solitary use, to arriving at better beliefs and decisions on our own. What reason does, rather, is help us justify our beliefs and actions to others, convince them through argumentation, and evaluate the justifications and arguments that others address to us.In other words, reason helps humans better exploit their uniquely rich social environment. This interactionist interpretation explains why reason may have evolved and how it fits with other cognitive mechanisms. It makes sense of strengths and weaknesses that have long puzzled philosophers and psychologists--why reason is biased in favor of what we already believe, why it may lead to terrible ideas and yet is indispensable to spreading good ones.Ambitious, provocative, and entertaining, The Enigma of Reason will spark debate among psychologists and philosophers, and make many reasonable people rethink their own thinking.

    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.
