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.

    They were hunter-gatherers, consummate foraging experts, but taking the world as they found it. Then a revolution occurred – our ancestors’ interaction with other species changed. They began to tame them. The human population boomed; civilization began.In her new book, Tamed, Alice Roberts uncovers the amazing deep history of ten familiar species with incredible wild pasts: dogs, apples and wheat; cattle; potatoes and chickens; rice, maize, and horses – and, finally, humans. Alice Roberts not only reveals how becoming part of our world changed these animals and plants, but shows how they became our allies, essential to the survival and success of our own species – and to our future.Enlightening, wide-ranging and endlessly fascinating, Tamed is an epic story, encompassing hundreds of thousands of years of history and archaeology alongside cutting-edge genetics and anthropology. Yet it is also a deeply personal journey that will change how we see ourselves and the species on which we have left our mark.

    In this thrill-ride across millennia and continents, the complete history of the planet comes to life: from the Earth's fiery birth to its near-obliteration in the Triassic period, and from the first signs of human life to the tentative future of a world with a burgeoning population and a global warming crisis. Covering a wide range of topics including astrophysics, zoology, and sociology, and complete with maps and illustrations, What on Earth Happened? In Brief is the endlessly entertaining story of the planet, life, and people.

    No one can stop him--but he walks away. A miracle? No...dysentery. Microbes saved the Roman Empire. Nearly a millennium later, the microbes of the Black Death ended the Middle Ages, making possible the Renaissance, western democracy, and the scientific revolution. Soon after, microbes ravaged the Americas, paving the way for their European conquest. Again and again, microbes have shaped our health, our genetics, our history, our culture, our politics, even our religion and ethics. This book reveals much that scientists and cultural historians have learned about the pervasive interconnections between infectious microbes and humans. It also considers what our ongoing fundamental relationship with infectious microbes might mean for the future of the human species. The "good side" of history's worst epidemics The surprising debt we owe to killer diseases Where diseases came from... ...and where they may be going Children of pestilence: disease and civilization From Egypt to Mexico, the Romans to Attila the Hun STDs, sexual behavior, and culture How microbes may shape cultural cycles of puritanism and promiscuity

    Beginning with the study of DNA in Egyptian mummies in the early 1980s and culminating in the sequencing of the Neanderthal genome in 2010, Neanderthal Man describes the events, intrigues, failures, and triumphs of these scientifically rich years through the lens of the pioneer and inventor of the field of ancient DNA.We learn that Neanderthal genes offer a unique window into the lives of our hominin relatives and may hold the key to unlocking the mystery of why humans survived while Neanderthals went extinct. Drawing on genetic and fossil clues, Pääbo explores what is known about the origin of modern humans and their relationship to the Neanderthals and describes the fierce debate surrounding the nature of the two species’ interactions. His findings have not only redrawn our family tree, but recast the fundamentals of human history—the biological beginnings of fully modern Homo sapiens, the direct ancestors of all people alive today.A riveting story about a visionary researcher and the nature of scientific inquiry, Neanderthal Man offers rich insight into the fundamental question of who we are.

    Beginning with the above questions, she began informally researching every affliction that she encountered in humans to learn whether it happened with animals, too. And usually, it did: dinosaurs suffered from brain cancer, koalas can catch chlamydia, reindeer seek narcotic escape in hallucinogenic mushrooms, stallions self-mutilate, and gorillas experience clinical depression. Natterson-Horowitz and science writer Kathryn Bowers have dubbed this pan-species approach to medicine zoobiquity. Here, they present a revelatory understanding of what animals can teach us about the human body and mind, exploring how animal and human commonality can be used to diagnose, treat, and heal patients of all species.

    The term “complexity” can be misleading, however, because what makes West’s discoveries so beautiful is that he has found an underlying simplicity that unites the seemingly complex and diverse phenomena of living systems, including our bodies, our cities and our businesses. Fascinated by issues of aging and mortality, West applied the rigor of a physicist to the biological question of why we live as long as we do and no longer. The result was astonishing, and changed science, creating a new understanding of energy use and metabolism: West found that despite the riotous diversity in the sizes of mammals, they are all, to a large degree, scaled versions of each other. If you know the size of a mammal, you can use scaling laws to learn everything from how much food it eats per day, what its heart-rate is, how long it will take to mature, its lifespan, and so on. Furthermore, the efficiency of the mammal’s circulatory systems scales up precisely based on weight: if you compare a mouse, a human and an elephant on a logarithmic graph, you find with every doubling of average weight, a species gets 25% more efficient—and lives 25% longer. This speaks to everything from how long we can expect to live to how many hours of sleep we need. Fundamentally, he has proven, the issue has to do with the fractal geometry of the networks that supply energy and remove waste from the organism's body. West's work has been game-changing for biologists, but then he made the even bolder move of exploring his work's applicability to cities. Cities, too, are constellations of networks and laws of scalability relate with eerie precision to them. For every doubling in a city's size, the city needs 15% less road, electrical wire, and gas stations to support the same population. More amazingly, for every doubling in size, cities produce 15% more patents and more wealth, as well as 15% more crime and disease. This broad pattern lays the groundwork for a new science of cities. Recently, West has applied his revolutionary work on cities and biological life to the business world. This investigation has led to powerful insights into why some companies thrive while others fail. The implications of these discoveries are far-reaching, and are just beginning to be explored. Scale is a thrilling scientific adventure story about the elemental natural laws that bind us together in simple but profound ways. Through the brilliant mind of Geoffrey West, we can envision how cities, companies and biological life alike are dancing to the same simple, powerful tune, however diverse and unrelated they are to each other.From the Hardcover edition.

    Why do men kill, rape, and wage war, and what can we do about it? Drawing on the latest discoveries about human evolution and about our closest living relatives, the great apes, Demonic Males offers some startling new answers. Dramatic, vivid, and firmly grounded in meticulous research, this book will change the way you see the world. As the San Francisco Chronicle said, it "dares to dig for the roots of a contentious and complicated subject that makes up much of our daily news."

    In college, I ran against Kenyans, and wondered whether endurance genes might have traveled with them from East Africa. At the same time, I began to notice that a training group on my team could consist of five men who run next to one another, stride for stride, day after day, and nonetheless turn out five entirely different runners. How could this be?We all knew a star athlete in high school. The one who made it look so easy. He was the starting quarterback and shortstop; she was the all-state point guard and high-jumper. Naturals. Or were they?The debate is as old as physical competition. Are stars like Usain Bolt, Michael Phelps, and Serena Williams genetic freaks put on Earth to dominate their respective sports? Or are they simply normal people who overcame their biological limits through sheer force of will and obsessive training?The truth is far messier than a simple dichotomy between nature and nurture. In the decade since the sequencing of the human genome, researchers have slowly begun to uncover how the relationship between biological endowments and a competitor’s training environment affects athleticism. Sports scientists have gradually entered the era of modern genetic research.In this controversial and engaging exploration of athletic success, Sports Illustrated senior writer David Epstein tackles the great nature vs. nurture debate and traces how far science has come in solving this great riddle. He investigates the so-called 10,000-hour rule to uncover whether rigorous and consistent practice from a young age is the only route to athletic excellence.Along the way, Epstein dispels many of our perceptions about why top athletes excel. He shows why some skills that we assume are innate, like the bullet-fast reactions of a baseball or cricket batter, are not, and why other characteristics that we assume are entirely voluntary, like an athlete’s will to train, might in fact have important genetic components.This subject necessarily involves digging deep into sensitive topics like race and gender. Epstein explores controversial questions such as:Are black athletes genetically predetermined to dominate both sprinting and distance running, and are their abilities influenced by Africa’s geography?Are there genetic reasons to separate male and female athletes in competition?Should we test the genes of young children to determine if they are destined for stardom?Can genetic testing determine who is at risk of injury, brain damage, or even death on the field?Through on-the-ground reporting from below the equator and above the Arctic Circle, revealing conversations with leading scientists and Olympic champions, and interviews with athletes who have rare genetic mutations or physical traits, Epstein forces us to rethink the very nature of athleticism.

    Why We Get Sick compels readers to reexamine the age-old attitudes toward sickness. Line drawings.

    For decades after the structure of DNA was identified, scientists focused purely on genes, the regions of the genome that contain codes for the production of proteins. Other regions - 98% of the human genome - were dismissed as 'junk'. But in recent years researchers have discovered that variations in this 'junk' DNA underlie many previously intractable diseases, and they can now generate new approaches to tackling them. Nessa Carey explores, for the first time for a general audience, the incredible story behind a controversy that has generated unusually vituperative public exchanges between scientists. She shows how junk DNA plays an important role in areas as diverse as genetic diseases, viral infections, sex determination in mammals, human biological complexity, disease treatments, even evolution itself - and reveals how we are only now truly unlocking its secrets, more than half a century after Crick and Watson won their Nobel prize for the discovery of the structure of DNA in 1962.
