Renowned primatologist Robert Sapolsky offers a completely revised and updated edition of his most popular work, with over 225,000 copies in print Now in a third edition, Robert M. Sapolsky's acclaimed and successful Why Zebras Don't Get Ulcers features new chapters on how stress affects sleep and addiction, as well as new insights into anxiety and personality disorder and the impact of spirituality on managing stress. As Sapolsky explains, most of us do not lie awake at night worrying about whether we have leprosy or malaria. Instead, the diseases we fear-and the ones that plague us now-are illnesses brought on by the slow accumulation of damage, such as heart disease and cancer. When we worry or experience stress, our body turns on the same physiological responses that an animal's does, but we do not resolve conflict in the same way-through fighting or fleeing. Over time, this activation of a stress response makes us literally sick. Combining cutting-edge research with a healthy dose of good humor and practical advice, Why Zebras Don't Get Ulcers explains how prolonged stress causes or intensifies a range of physical and mental afflictions, including depression, ulcers, colitis, heart disease, and more. It also provides essential guidance to controlling our stress responses. This new edition promises to be the most comprehensive and engaging one yet.

Finalist for the Los Angeles Times Book Prize From the man who Oliver Sacks hailed as “one of the best scientist/writers of our time,” a collection of sharply observed, uproariously funny essays on the biology of human culture and behavior. In the tradition of Stephen Jay Gould and Oliver Sacks, Robert Sapolsky offers a sparkling and erudite collection of essays about science, the world, and our relation to both. “The Trouble with Testosterone” explores the influence of that notorious hormone on male aggression. “Curious George’s Pharmacy” reexamines recent exciting claims that wild primates know how to medicate themselves with forest plants. “Junk Food Monkeys” relates the adventures of a troop of baboons who stumble upon a tourist garbage dump. And “Circling the Blanket for God” examines the neurobiological roots underlying religious belief. Drawing on his career as an evolutionary biologist and neurobiologist, Robert Sapolsky writes about the natural world vividly and insightfully. With candor, humor, and rich observations, these essays marry cutting-edge science with humanity, illuminating the interconnectedness of the world’s inhabitants with skill and flair.

A collection of original essays by a leading neurobiologist and primatologist share the author's insights into behavioral biology, including discussion of the physiology of genes and the factors that shape human social interaction.

New York Times bestseller • Winner of the Los Angeles Times Book Prize • One of the Washington Post's 10 Best Books of the Year “It’s no exaggeration to say that Behave is one of the best nonfiction books I’ve ever read.” —David P. Barash, The Wall Street Journal "It has my vote for science book of the year.” —Parul Sehgal, The New York Times "Immensely readable, often hilarious...Hands-down one of the best books I’ve read in years. I loved it." —Dina Temple-Raston, The Washington Post From the bestselling author of A Primate's Memoir and the forthcoming Determined: A Science of Life Without Free Will comes a landmark, genre-defining examination of human behavior and an answer to the question: Why do we do the things we do? Behave is one of the most dazzling tours d’horizon of the science of human behavior ever attempted. Moving across a range of disciplines, Sapolsky—a neuroscientist and primatologist—uncovers the hidden story of our actions. Undertaking some of our thorniest questions relating to tribalism and xenophobia, hierarchy and competition, and war and peace, Behave is a towering achievement—a majestic synthesis of cutting-edge research and a heroic exploration of why we ultimately do the things we do . . . for good and for ill.

In the tradition of Jane Goodall and Dian Fossey, Robert Sapolsky, a foremost science writer and recipient of a MacArthur Genius Grant, tells the mesmerizing story of his twenty-one years in remote Kenya with a troop of savanna baboons. "I had never planned to become a savanna baboon when I grew up; instead, I had always assumed I would become a mountain gorilla,” writes Robert Sapolsky in this witty and riveting chronicle of a scientist’s coming-of-age in Africa. An exhilarating account of Sapolsky’s twenty-one-year study of a troop of rambunctious baboons in Kenya, A Primate’s Memoir interweaves serious scientific observations with wry commentary about the challenges and pleasures of living in the wilds of the Serengeti—for man and beast alike. Over two decades, Sapolsky survives culinary atrocities, gunpoint encounters, and a surreal kidnapping, while witnessing the encroachment of the tourist mentality on Africa. As he conducts unprecedented physiological research on wild primates, he becomes enamored of his subjects—unique and compelling characters in their own right—and he returns to them summer after summer, until tragedy finally prevents him. By turns hilarious and poignant, A Primate’s Memoir is a magnum opus from one of our foremost science writers.

Drawing from groundbreaking research, psychologist and award-winning teacher Kelly McGonigal, PhD, offers a surprising new view of stress—one that reveals the upside of stress, and shows us exactly how to capitalize on its benefits. You hear it all the time: stress causes heart disease; stress causes insomnia; stress is bad for you! But what if changing how you think about stress could make you happier, healthier, and better able to reach your goals? Combining exciting new research on resilience and mindset, Kelly McGonigal, PhD, proves that undergoing stress is not bad for you; it is undergoing stress while believing that stress is bad for you that makes it harmful. In fact, stress has many benefits, from giving us greater focus and energy, to strengthening our personal relationships. McGonigal shows readers how to cultivate a mindset that embraces stress, and activate the brain's natural ability to learn from challenging experiences. Both practical and life-changing, The Upside of Stress is not a guide to getting rid of stress, but a toolkit for getting better at it—by understanding, accepting, and leveraging it to your advantage.

The first edited collection to explore one of the most rapidly growing area of philosophy: political epistemology. The volume brings together leading philosophers to explore ways in which the analytic and conceptual tools of epistemology bear on political philosophy--and vice versa.

Why do giraffes have such long necks? Why are zebras striped? And why does the clitoris of the female hyena exactly resemble and in most respects function like the male's penis?Deploying the latest scientific research and his own extensive observations in Africa, Léo Grasset offers answers to these questions and many more in a book of post-Darwinian Just So stories. Complex natural phenomena are explained in simple and at times comic terms, as Grasset turns evolutionary biology to the burning questions of the animal kingdom, from why elephants prefer dictators and buffaloes democracies, to whether the lion really is king.The human is, of course, just another animal, and the author's exploration of two million years of human evolution shows how it not only informs our current habits and behavior, but reveals that we are hybrids of several different species.Prepare to be fascinated, shocked and delighted, as well as reliably advised — by the end, you will know to never hug the beautiful, cuddly honey badger, and what explains its almost psychotic nastiness.This is serious science at its entertaining best.
