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.

The Blind Watchmaker, knowledgably narrated by author Richard Dawkins, is as prescient and timely a book as ever. The watchmaker belongs to the 18th-century theologian William Paley, who argued that just as a watch is too complicated and functional to have sprung into existence by accident, so too must all living things, with their far greater complexity, be purposefully designed. Charles Darwin's brilliant discovery challenged the creationist arguments; but only Richard Dawkins could have written this elegant riposte.

Why evolution is more than just a theory: it is a fact. In all the current highly publicized debates about creationism and its descendant "intelligent design", there is an element of the controversy that is rarely mentioned: the evidence, the empirical truth of evolution by natural selection.

In The Ancestor's Tale, evolutionary biologist Richard Dawkins offers a masterwork: an exhilarating reverse tour through evolution, from present-day humans back to the microbial beginnings of life four billion years ago. Throughout the journey, Dawkins spins entertaining, insightful stories and sheds light on topics such as speciation, sexual selection, and extinction. The Ancestor's Tale is at once an essential education in evolutionary theory and riveting in its telling.

The late great astronomer and astrophysicist describes his personal search to understand the nature of the sacred in the vastness of the cosmos. Exhibiting a breadth of intellect nothing short of astounding, Sagan presents his views on a wide range of topics, including the likelihood of intelligent life on other planets, creationism and so-called intelligent design.

In The Lives of a Cell, Dr. Lewis Thomas opens up to the listener a universe of knowledge and perception that is perhaps not wholly unfamiliar to the research scientist; but the world he explores is also one of men and women, of complex interrelationships, old ironies, peculiar powers, and intricate languages that give identity to the alienated and direction to the dependent. This remarkable work offers a subtle, bold vision of humankind and the world around us - a sense of what gives life - from a writer who seems to draw grace and strength from the very substance of his subject.

In movies, in novels, in comic strips, and on television, we've all seen dinosaurs - or at least somebody's educated guess of what they would look like. But what if it were possible to build, or grow, a real dinosaur without finding ancient DNA? Jack Horner, the scientist who advised Steven Spielberg on the blockbuster film Jurassic Park and a pioneer in bringing paleontology into the 21st century, teams up with the editor of the New York Times's Science Times section to reveal exactly what's in store.

Blending biology, chemistry, and physics basics with accessible - and witty-prose, The Science of Rick and Morty equips you with the scientific foundation to thoroughly understand Rick's experiments from the show, such as how we can use dark matter and energy, just what is intelligence hacking, and whether or not you can really control a cockroach's nervous system with your tongue. Perfect for longtime and new fans of the show, this is the ultimate segue into discovering more about our complicated and fascinating universe.

In The Equations of Life, biologist Charles S. Cockell makes the forceful argument that the laws of physics narrowly constrain how life can evolve, making evolution's outcomes predictable. If we were to find something very much like a lady bug eating something very much like an aphid on a distant planet, we shouldn't be surprised. The forms of life are guided by a limited set of rules, and, as a result, there is a narrow set of solutions to the challenges of existence.

Mankind has a distinct advantage over other terrestrial species: we talk to one another. But how did we acquire the most advanced form of communication on Earth? Daniel L. Everett, a "bombshell" linguist and "instant folk hero" (Tom Wolfe, Harper's), provides in this sweeping history a comprehensive examination of the evolutionary story of language, from the earliest speaking attempts by hominids to the more than 7,000 languages that exist today.

Throughout his distinguished and unconventional career, engineer-turned-molecular-biologist Douglas Axe has been asking the questions that much of the scientific community would rather silence. Now, he presents his conclusions in this brave and pioneering book. Axe argues that the key to understanding our origin is the "design intuition" - the innate belief held by all humans that tasks we would need knowledge to accomplish can be accomplished only by someone who has that knowledge.

Geneticist Adam Rutherford and mathematician Hannah Fry guide listeners through time and space, through our bodies and brains, showing how emotions shape our view of reality, how our minds tell us lies, and why a mostly bald and curious ape decided to begin poking at the fabric of the universe.

The atom, the big bang, DNA, natural selection - all are ideas that have revolutionized science; and all were dismissed out of hand when they first appeared. The surprises haven't stopped in recent years, and in At the Edge of Uncertainty, best-selling author Michael Brooks investigates the new wave of radical insights that are shaping the future of scientific discovery.

Over the past 20 years, paleontologists have made tremendous fossil discoveries, including fossils that mark the growth of whales, manatees, and seals from land mammals and the origins of elephants, horses, and rhinos. Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before.

Seventy years ago, Erwin Schrdinger posed a simple, yet profound, question: What is life?. How could the very existence of such extraordinary chemical systems be understood? This problem has puzzled biologists and physical scientists both before, and ever since. Living things are hugely complex and have unique properties, such as self-maintenance and apparently purposeful behaviour which we do not see in inert matter. So how does chemistry give rise to biology?

Edward O. Wilson has distilled sixty years of teaching into a book for students, young and old. Reflecting on his coming-of-age in the South as a Boy Scout and a lover of ants and butterflies, Wilson threads these twenty-one letters, each richly illustrated, with autobiographical anecdotes that illuminate his career - both his successes and his failures - and his motivations for becoming a biologist.

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.

Why Animals Talk is an exhilarating journey through the untamed world of animal communication. Following his international bestseller, The Zoologist’s Guide to the Galaxy, acclaimed zoologist Arik Kershenbaum draws on extensive original research to reveal how many of the animal kingdom’s most seemingly confusing or untranslatable signals are in fact logical and consistent—and not that different from our own.

An enthralling account of a modern voyage of discovery as we meet the clever, social birds of prey called caracaras, which puzzled Darwin, fascinate modern-day falconers, and carry secrets of our planet's deep past in their family history.

In these 24 lectures, The Great Courses teams up with the Smithsonian’s National Zoo and Conservation Biology Institute, to take you behind the scenes of the animal world. Dr. Moore has crafted a wonderful introduction to zoology that brings you up close and personal with a breathtaking variety of animal species through the eyes of a trained zoologist.

Carl Zimmer investigates one of the biggest questions of all: What is life? The answer seems obvious until you try to seriously answer it. Is the apple sitting on your kitchen counter alive, or is only the apple tree it came from deserving of the word? If we can’t answer that question here on Earth, how will we know when and if we discover alien life on other worlds? The question hangs over some of society’s most charged conflicts - whether a fertilized egg is a living person, for example, and when we ought to declare a person legally dead.

It is now known that we live in a galaxy with more planets than stars. The Milky Way alone encompasses 30 trillion potential home planets. Scientists Trefil and Summers bring listeners on a marvelous experimental voyage through the possibilities of life-unlike anything we have experienced so far - that could exist on planets outside our own solar system.

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.

Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth, and together may contain more than 50 times its total volume of liquid water. Could there be organisms living in their depths?

Dip below the ocean’s surface and you are soon confronted by forms of life that could not seem more foreign to our own: sea sponges, soft corals, and serpulid worms, whose rooted bodies, intricate geometry, and flower-like appendages are more reminiscent of plant life or even architecture than anything recognizably animal. Yet these creatures are our cousins. As fellow members of the animal kingdom — the Metazoa— they can teach us much about the evolutionary origins of not only our bodies, but also our minds.

Seventy years ago, Erwin Schrdinger posed a simple, yet profound, question: What is life?. How could the very existence of such extraordinary chemical systems be understood? This problem has puzzled biologists and physical scientists both before, and ever since.
