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.

    As audacious as it is edifying, here is a hilarious and irreverent—yet always historically accurate—overview of the ascent (or descent) of humankind, courtesy of the same rebel geniuses who brought you Mental Floss presents Condensed Knowledge and Mental Floss Presents Forbidden Knowledge. Updated with all the hot topics and events of the past few years, The Mental Floss History of the World is proof positive that just because something’s true doesn’t mean it’s boring.

    Tell a stranger that you talk to yourself, and you're likely to get written off as eccentric. But the truth is that we all have a voice in our head. When we talk to ourselves, we often hope to tap into our inner coach but find our inner critic instead. When we're facing a tough task, our inner coach can buoy us up: Focus--you can do this. But, just as often, our inner critic sinks us entirely: I'm going to fail. They'll all laugh at me. What's the use?In Chatter, acclaimed psychologist Ethan Kross explores the silent conversations we have with ourselves. Interweaving groundbreaking behavioral and brain research from his own lab with real-world case studies--from a pitcher who forgets how to pitch, to a Harvard undergrad negotiating her double life as a spy--Kross explains how these conversations shape our lives, work, and relationships. He warns that giving in to negative and disorienting self-talk--what he calls "chatter"--can tank our health, sink our moods, strain our social connections, and cause us to fold under pressure.But the good news is that we're already equipped with the tools we need to make our inner voice work in our favor. These tools are often hidden in plain sight--in the words we use to think about ourselves, the technologies we embrace, the diaries we keep in our drawers, the conversations we have with our loved ones, and the cultures we create in our schools and workplaces.Brilliantly argued, expertly researched, and filled with compelling stories, Chatter gives us the power to change the most important conversation we have each day: the one we have with ourselves.

    Gut, an international bestseller, gives the alimentary canal its long-overdue moment in the spotlight. With quirky charm, rising science star Giulia Enders explains the gut’s magic, answering questions like: Why does acid reflux happen? What’s really up with gluten and lactose intolerance? How does the gut affect obesity and mood? Communication between the gut and the brain is one of the fastest-growing areas of medical research—on par with stem-cell research. Our gut reactions, we learn, are intimately connected with our physical and mental well-being. Enders’s beguiling manifesto will make you finally listen to those butterflies in your stomach: they’re trying to tell you something important.

     His starting point is moral intuition—the nearly instantaneous perceptions we all have about other people and the things they do. These intuitions feel like self-evident truths, making us righteously certain that those who see things differently are wrong. Haidt shows us how these intuitions differ across cultures, including the cultures of the political left and right. He blends his own research findings with those of anthropologists, historians, and other psychologists to draw a map of the moral domain. He then examines the origins of morality, overturning the view that evolution made us fundamentally selfish creatures. But rather than arguing that we are innately altruistic, he makes a more subtle claim—that we are fundamentally groupish. It is our groupishness, he explains, that leads to our greatest joys, our religious divisions, and our political affiliations. In a stunning final chapter on ideology and civility, Haidt shows what each side is right about, and why we need the insights of liberals, conservatives, and libertarians to flourish as a nation.

    They are the ones who prefer listening to speaking; who innovate and create but dislike self-promotion; who favor working on their own over working in teams. It is to introverts—Rosa Parks, Chopin, Dr. Seuss, Steve Wozniak—that we owe many of the great contributions to society. In Quiet, Susan Cain argues that we dramatically undervalue introverts and shows how much we lose in doing so. She charts the rise of the Extrovert Ideal throughout the twentieth century and explores how deeply it has come to permeate our culture. She also introduces us to successful introverts—from a witty, high-octane public speaker who recharges in solitude after his talks, to a record-breaking salesman who quietly taps into the power of questions. Passionately argued, superbly researched, and filled with indelible stories of real people, Quiet has the power to permanently change how we see introverts and, equally important, how they see themselves.Now with Extra Libris material, including a reader’s guide and bonus content.

    Exploring the history of cannibalism, the neurology of people who are sexually attracted to animals, the evolution of human body fluids, the science of homosexuality, and serious questions about life and death, Bering astutely covers a generous expanse of our kaleidoscope of quirks and origins.With his characteristic irreverence and trademark cheekiness, Bering leaves no topic unturned or curiosity unexamined, and he does it all with an audaciously original voice. Whether you're interested in the psychological history behind the many facets of sexual desire or the evolutionary patterns that have dictated our current mystique and phallic physique, Why Is the Penis Shaped Like That? is bound to create lively discussion and debate for years to come.

    The disaster not only changed the world’s perception of nuclear power and the science that spawned it, but also our understanding of the planet’s delicate ecology. With the images of the abandoned homes and playgrounds beyond the barbed wire of the 30-kilometer Exclusion Zone, the rusting graveyards of contaminated trucks and helicopters, the farmland lashed with black rain, the event fixed for all time the notion of radiation as an invisible killer.Chernobyl was also a key event in the destruction of the Soviet Union, and, with it, the United States’ victory in the Cold War. For Moscow, it was a political and financial catastrophe as much as an environmental and scientific one. With a total cost of 18 billion rubles—at the time equivalent to $18 billion—Chernobyl bankrupted an already teetering economy and revealed to its population a state built upon a pillar of lies. The full story of the events that started that night in the control room of Reactor No.4 of the V.I. Lenin Nuclear Power Plant has never been told—until now. Through two decades of reporting, new archival information, and firsthand interviews with witnesses, journalist Adam Higginbotham tells the full dramatic story, including Alexander Akimov and Anatoli Dyatlov, who represented the best and worst of Soviet life; denizens of a vanished world of secret policemen, internal passports, food lines, and heroic self-sacrifice for the Motherland. Midnight in Chernobyl, award-worthy nonfiction that reads like sci-fi, shows not only the final epic struggle of a dying empire but also the story of individual heroism and desperate, ingenious technical improvisation joining forces against a new kind of enemy.

    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.

    What will she do? And what are the implications for her behavior later in life?The world's leading expert on self-control, Walter Mischel has proven that the ability to delay gratification is critical for a successful life, predicting higher SAT scores, better social and cognitive functioning, a healthier lifestyle and a greater sense of self-worth. But is willpower prewired, or can it be taught?In The Marshmallow Test, Mischel explains how self-control can be mastered and applied to challenges in everyday life—from weight control to quitting smoking, overcoming heartbreak, making major decisions, and planning for retirement. With profound implications for the choices we make in parenting, education, public policy and self-care, The Marshmallow Test will change the way you think about who we are and what we can be.

    But do those of us who accept the reality of human-caused climate change truly believe it? If we did, surely we would be roused to act on what we know. Will future generations distinguish between those who didn’t believe in the science of global warming and those who said they accepted the science but failed to change their lives in response?In We Are the Weather, Jonathan Safran Foer explores the central global dilemma of our time in a surprising, deeply personal, and urgent new way. The task of saving the planet will involve a great reckoning with ourselves—with our all-too-human reluctance to sacrifice immediate comfort for the sake of the future. We have, he reveals, turned our planet into a farm for growing animal products, and the consequences are catastrophic. Only collective action will save our home and way of life. And it all starts with what we eat—and don’t eat—for breakfast.

    Now she builds on those insights to show us how to give our animals the best and happiest life—on their terms, not ours.It’s usually easy to pinpoint the cause of physical pain in animals, but to know what is causing them emotional distress is much harder. rawing on the latest research and her own work,Grandin identifies the core emotional needs of animals. Then she explains how to fulfill them for dogs and cats, horses, farm animals, and zoo animals.Whether it’s how to make the healthiest environment for the dog you must leave alone most of the day, how to keep pigs from being bored, or how to know if the lion pacing in the zoo is miserable or just exercising, Grandin teaches us to challenge our assumptions about animal contentment and honor our bond with our fellow creatures.Animals Make Us Human is the culmination of almost thirty years of research, experimentation, and experience.This is essential reading for anyone who’s ever owned, cared for, or simply cared about an animal.

    In The Ends of the World, Peter Brannen dives into deep time, exploring Earth’s past dead ends, and in the process, offers us a glimpse of our possible future.Many scientists now believe that the climate shifts of the twenty-first century have analogs in these five extinctions. Using the visible clues these devastations have left behind in the fossil record, The Ends of the World takes us inside “scenes of the crime,” from South Africa to the New York Palisades, to tell the story of each extinction. Brannen examines the fossil record—which is rife with creatures like dragonflies the size of sea gulls and guillotine-mouthed fish—and introduces us to the researchers on the front lines who, using the forensic tools of modern science, are piecing together what really happened at the crime scenes of the Earth’s biggest whodunits.Part road trip, part history, and part cautionary tale, The Ends of the World takes us on a tour of the ways that our planet has clawed itself back from the grave, and casts our future in a completely new light.

    When Matt Haig developed panic disorder, anxiety, and depression as an adult, it took him a long time to work out the ways the external world could impact his mental health in both positive and negative ways. Notes on a Nervous Planet collects his observations, taking a look at how the various social, commercial and technological "advancements" that have created the world we now live in can actually hinder our happiness. Haig examines everything from broader phenomena like inequality, social media, and the news; to things closer to our daily lives, like how we sleep, how we exercise, and even the distinction we draw between our minds and our bodies.

    Starting once again with fossils, he turns his gaze skyward, showing us how the entirety of the universe’s fourteen-billion-year history can be seen in our bodies. As he moves from our very molecular composition (a result of stellar events at the origin of our solar system) through the workings of our eyes, Shubin makes clear how the evolution of the cosmos has profoundly marked our own bodies.
