The past is past, but it does leave clues, and Thomas Halliday has used cutting-edge science to decipher them more completely than ever before. In Otherlands, Halliday makes sixteen fossil sites burst to life.

Dr. Carl Sagan takes us on a great adventure, offering his vivid and startling insight into the brain of man and beast, the origin of human intelligence, the function of our most haunting legends - and their amazing links to recent discoveries.

A lifetime of adventures with bats around the world reveals why these special and imperiled creatures should be protected rather than feared.

We humans like to think of ourselves as highly evolved creatures. But if we are supposedly evolution's greatest creation, why do we have such bad knees? Why do we catch head colds so often - 200 times more often than a dog does? How come our wrists have so many useless bones? And are we really supposed to swallow and breathe through the same narrow tube? Surely there's been some kind of mistake. As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is nothing if not a litany of mistakes, each more entertaining and enlightening than the last.

The number-one best-selling author of The Future of the Mind traverses the frontiers of astrophysics, artificial intelligence, and technology to offer a stunning vision of man's future in space, from settling Mars to traveling to distant galaxies. Formerly the domain of fiction, moving human civilization to the stars is increasingly becoming a scientific possibility - and a necessity. Whether in the near future due to climate change and the depletion of finite resources or in the distant future due to catastrophic cosmological events, humans will one day need to leave Earth.

A cataclysmic planetary phenomenon is gathering force deep within the Earth. The magnetic North Pole will eventually trade places with the South Pole. Satellite evidence suggests to some scientists that the move has already begun, but most still think it won't happen for many decades. All agree that it has happened many times before and will happen again. But this time it will be different. It will be a very bad day for modern civilization.

As a Yale School of Medicine physician, the New York Times best-selling author of Every Patient Tells a Story, and an inspiration and adviser for the hit Fox TV drama, House, M.D., Lisa Sanders has seen it all. And yet, she is often confounded by the cases she describes in her column: unexpected collections of symptoms that she and other physicians struggle to diagnose. Dr. Sanders shows how making the right diagnosis requires expertise, painstaking procedure, and sometimes a little luck.

"There is the mammal way and there is the bird way." But the bird way is much more than a unique pattern of brain wiring, and lately, scientists have taken a new look at bird behaviors they have, for years, dismissed as anomalies or mysteries - what they are finding is upending the traditional view of how birds conduct their lives, how they communicate, forage, court, breed, survive. They are also revealing the remarkable intelligence underlying these activities, abilities we once considered uniquely our own.

For over three decades, Ray Kurzweil has been one of the most respected and provocative advocates of the role of technology in our future. In his classic The Age of Spiritual Machines, he argued that computers would soon rival the full range of human intelligence at its best. Now he examines the next step in this inexorable evolutionary process: The union of human and machine, in which the knowledge and skills embedded in our brains will be combined with the vastly greater capacity, speed, and knowledge-sharing ability of our creations.

Status signaling isn’t just the province of the immature or insecure but a fundamental human need to secure social standing. It drives our behavior, forms our tastes, determines what we buy, and ultimately shapes who we are. It’s what’s behind “cool” and what drives fashion, music, food, sports, slang, travel, hairstyles, and dog breeds—and even the outsize influence of unpopular things with the “right” audience.

For the first time, in Fifth Sun, the history of the Aztecs is offered in all its complexity based solely on the texts written by the indigenous people themselves. Camilla Townsend presents an accessible and humanized depiction of these native Mexicans, rather than seeing them as the exotic, bloody figures of European stereotypes.

Robert Greene is a master guide for millions of listeners, distilling ancient wisdom and philosophy into essential texts for seekers of power, understanding, and mastery. Now he turns to the most important subject of all - understanding people's drives and motivations, even when they are unconscious of them themselves. Whether at work, in relationships, or in shaping the world around you, The Laws of Human Nature offers brilliant tactics for success, self-improvement, and self-defense.

Just over 125,000 years ago, humanity was going extinct until a dramatic shift occurred—Homo sapiens started tracking the tides in order to eat the nearby oysters. Before long, they’d pulled themselves back from the brink of extinction. The human brain, and its evolutionary journey, is unlike anything else in history. In A History of the Human Brain, Bret Stetka takes listeners through that far-reaching journey. He also tackles the question of where the brain will take us next, exploring the burgeoning con­cepts of epigenetics and new technologies like CRISPR.

The world's largest land mammal could help us end cancer. The fastest bird is showing us how to solve a century-old engineering mystery. The oldest tree is giving us insights into climate change. The loudest whale is offering clues about the impact of solar storms. For a long time, scientists ignored superlative life forms as outliers. Increasingly, though, researchers are coming to see great value in studying plants and animals that exist on the outermost edges of the bell curve.

Sparked by a controversial debate in February 2014, Bill Nye has set off on an energetic campaign to spread awareness of evolution and the powerful way it shapes our lives. In Undeniable: Evolution and the Science of Creation, he explains why race does not really exist; evaluates the true promise and peril of genetically modified food; reveals how new species are born, in a dog kennel and in a London subway; takes a stroll through 4.5 billion years of time; and explores the new search for alien life, including aliens right here on Earth.

Harry Cliff - a University of Cambridge particle physicist and researcher on the Large Hadron Collider - sets out in pursuit of answers. He ventures to the largest underground research facility in the world, deep beneath Italy's Gran Sasso mountains, where scientists gaze into the heart of the Sun using the most elusive of particles, the ghostly neutrino. He visits CERN in Switzerland to explore the "Antimatter Factory," where the stuff of science fiction is manufactured daily (and we're close to knowing whether it falls up).

In the eighteenth century, two men—exact contemporaries and polar opposites—dedicated their lives to the same daunting task: identifying and describing all life on Earth. Carl Linnaeus, a pious Swedish doctor with a huckster’s flair, believed that life belonged in tidy, static categories. Georges-Louis de Buffon, an aristocratic polymath and keeper of France’s royal garden, viewed life as a dynamic swirl of complexities. Each began his task believing it to be difficult but not impossible: How could the planet possibly hold more than a few thousand species—or as many could fit on Noah’s Ark?

For decades Richard Dawkins has been the world's most brilliant scientific communicator, consistently illuminating the wonders of nature and attacking faulty logic. Science in the Soul brings together 42 essays, polemics, and paeans - culled from personal papers, newspapers, lectures, and online salons - all written with Dawkins' characteristic erudition, remorseless wit, and unjaded awe of the natural world.

A compassionate and captivating examination of evolving attitudes toward mental illness throughout history and the fight to end the stigma. For centuries, scientists and society cast moral judgments on anyone deemed mentally ill, confining many to asylums. In Nobody’s Normal, anthropologist Roy Richard Grinker chronicles the progress and setbacks in the struggle against mental-illness stigma - from the 18th century, through America’s major wars, and into today’s high-tech economy.

In 40 years, Earth's population will reach 10 billion. Can our world support that? What kind of world will it be? Those answering these questions generally fall into two deeply divided groups - Wizards and Prophets, as Charles Mann calls them in this balanced, authoritative, nonpolemical new book. The Prophets, he explains, follow William Vogt, a founding environmentalist who believed that in using more than our planet has to give, our prosperity will lead us to ruin.

Long before books were mass-produced, hand-copied scrolls made from Nile River reeds were the treasures of the ancient world. Emperors and pharaohs, determined to possess them, dispatched emissaries to the edges of the known world to bring them back. Exploring the deep and fascinating history of the written word, from the oral tradition to scrolls to codices, internationally bestselling author Irene Vallejo shows that books have always been a precious and precarious vehicle for civilization.

Renowned neuroscientist Joseph LeDoux digs into the natural history of life on earth to provide a new perspective on the similarities between us and our ancestors in deep time. This pause-resisting survey of the whole of terrestrial evolution sheds new light on how nervous systems evolved in animals, how the brain developed, and what it means to be human. In The Deep History of Ourselves, LeDoux argues that the key to understanding human behavior lies in viewing evolution through the prism of the first living organisms.

From University of Washington professor Chantel Prat comes The Neuroscience of You, a rollicking adventure into the human brain that reveals the surprising truth about neuroscience, shifting our focus from what’s average to an understanding of how every brain is different, exactly why our quirks are important, and what this means for each of us.

For centuries, people have been returning to the same tired nature-versus-nurture debate, trying to determine what we learn and what we inherit. In Dancing Cockatoos and the Dead Man Test, biologist Marlene Zuk goes beyond the binary and instead focuses on interaction, or the way that genes and environment work together. Driving her investigation is a simple but essential question: How does behavior evolve?

Elinor Cleghorn became an unwell woman 10 years ago. She was diagnosed with an autoimmune disease after a long period of being told her symptoms were anything from psychosomatic to a possible pregnancy. As Elinor learned to live with her unpredictable disease, she turned to history for answers, and found an enraging legacy of suffering, mystification, and misdiagnosis. In Unwell Women, Elinor Cleghorn traces the almost unbelievable history of how medicine has failed women by treating their bodies as alien and other, often to perilous effect.

Already internationally acclaimed for his elegant, lucid writing on the most challenging notions in modern physics, Sean Carroll is emerging as one of the greatest humanist thinkers of his generation as he brings his extraordinary intellect to bear not only on the Higgs boson and extra dimensions but now also on our deepest personal questions. Where are we? Who are we? Are our emotions, our beliefs, and our hopes and dreams ultimately meaningless out there in the void?

Around four thousand years ago, the mysterious Minoans sculpted statues of topless women with snakes slithering on their arms. Over one thousand years later, Sappho wrote great poems of longing and desire. For classicist Daisy Dunn, these women—whether they were simply sitting at their looms at home or participating in the highest echelons of power—were up to something much more interesting than other histories would lead us to believe. Together, these women helped to make antiquity as we know it.
