An assessment of human evolution that theorizes that many more species of humans than previously thought have existed during the six million year history of the hominid family.

In its 4.5 billion–year history, life on Earth has been almost erased at least half a dozen times: shattered by asteroid impacts, entombed in ice, smothered by methane, and torn apart by unfathomably powerful megavolcanoes. And we know that another global disaster is eventually headed our way. Can we survive it? How? As a species, Homo sapiens is at a crossroads. Study of our planet’s turbulent past suggests that we are overdue for a catastrophic disaster, whether caused by nature or by human interference. It’s a frightening prospect, as each of the Earth’s past major disasters—from meteor strikes to bombardment by cosmic radiation—resulted in a mass extinction, where more than 75 percent of the planet’s species died out. But in Scatter, Adapt, and Remember, Annalee Newitz, science journalist and editor of the science Web site io9.com explains that although global disaster is all but inevitable, our chances of long-term species survival are better than ever. Life on Earth has come close to annihilation—humans have, more than once, narrowly avoided extinction just during the last million years—but every single time a few creatures survived, evolving to adapt to the harshest of conditions. This brilliantly speculative work of popular science focuses on humanity’s long history of dodging the bullet, as well as on new threats that we may face in years to come. Most important, it explores how scientific breakthroughs today will help us avoid disasters tomorrow. From simulating tsunamis to studying central Turkey’s ancient underground cities; from cultivating cyanobacteria for “living cities” to designing space elevators to make space colonies cost-effective; from using math to stop pandemics to studying the remarkable survival strategies of gray whales, scientists and researchers the world over are discovering the keys to long-term resilience and learning how humans can choose life over death. Newitz’s remarkable and fascinating journey through the science of mass extinctions is a powerful argument about human ingenuity and our ability to change. In a world populated by doomsday preppers and media commentators obsessively forecasting our demise, Scatter, Adapt, and Remember is a compelling voice of hope. It leads us away from apocalyptic thinking into a future where we live to build a better world—on this planet and perhaps on others. Readers of this book will be equipped scientifically, intellectually, and emotionally to face whatever the future holds.

Are we in imminent danger of extinction? Yes, we probably are, argues John Leslie in his chilling account of the dangers facing the human race as we approach the second millenium. The End of the World is a sobering assessment of the many disasters that scientists have predicted and speculated on as leading to apocalypse. In the first comprehensive survey, potential catastrophes - ranging from deadly diseases to high-energy physics experiments - are explored to help us understand the risks. One of the greatest threats facing humankind, however, is the insurmountable fact that we are a relatively young species, a risk which is at the heart of the 'Doomsday Argument'. This argument, if correct, makes the dangers we face more serious than we could have ever imagined. This more than anything makes the arrogance and ignorance of politicians, and indeed philosophers, so disturbing as they continue to ignore the manifest dangers facing future generations.

ONE OF THE NEW YORK TIMES BOOK REVIEW'S 10 BEST BOOKS OF THE YEAR A major book about the future of the world, blending intellectual and natural history and field reporting into a powerful account of the mass extinction unfolding before our eyes Over the last half a billion years, there have been five mass extinctions, when the diversity of life on earth suddenly and dramatically contracted. Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In The Sixth Extinction, two-time winner of the National Magazine Award and New Yorker writer Elizabeth Kolbert draws on the work of scores of researchers in half a dozen disciplines, accompanying many of them into the field: geologists who study deep ocean cores, botanists who follow the tree line as it climbs up the Andes, marine biologists who dive off the Great Barrier Reef. She introduces us to a dozen species, some already gone, others facing extinction, including the Panamian golden frog, staghorn coral, the great auk, and the Sumatran rhino. Through these stories, Kolbert provides a moving account of the disappearances occurring all around us and traces the evolution of extinction as concept, from its first articulation by Georges Cuvier in revolutionary Paris up through the present day. The sixth extinction is likely to be mankind's most lasting legacy; as Kolbert observes, it compels us to rethink the fundamental question of what it means to be human.

Let’s learn about the most mystifying species to ever walk the Earth! Plib is like every other Nøørfbløøk kid on Earth, except for one thing. He loves humans--those horrible, terrifying monsters who dominated the planet ten million years ago. Only one thing about the humans bothers Plib. What happened to them all? Did they turn the planet into an uninhabitable wasteland? Or did they turn on each other? Or did the humans die out because of something else they did--or didn’t--do? Find the answer in How Did Humans Go Extinct?

"This book shows us the face of Earth’s sixth great mass extinction, revealing that this century is a time of darkness for the world’s birds and mammals. In The Annihilation of Nature, three of today’s most distinguished conservationists tell the stories of the birds and mammals we have lost and those that are now on the road to extinction. These tragic tales, coupled with eighty-three color photographs from the world’s leading nature photographers, display the beauty and biodiversity that humans are squandering."--Book jacket.

Tomorrow has never looked better. Breakthroughs in fields like genetic engineering and nanotechnology promise to give us unprecedented power to redesign our bodies and our world. Futurists and activists tell us that we are drawing ever closer to a day when we will be as smart as computers, will be able to link our minds telepathically, and will live for centuries—or maybe forever. The perfection of a “post-human” future awaits us. Or so the story goes. In reality, the rush toward a post-human destiny amounts to an ideology of human extinction, an ideology that sees little of value in humanity except the raw material for producing whatever might come next. In Eclipse of Man, Charles T. Rubin traces the intellectual origins of the movement to perfect and replace the human race. He shows how today’s advocates of radical enhancement are—like their forebears—deeply dissatisfied with given human nature and fixated on grand visions of a future shaped by technological progress. Moreover, Rubin argues that this myopic vision of the future is not confined to charlatans and cheerleaders promoting this or that technology: it also runs through much of modern science and contemporary progressivism. By exploring and criticizing the dreams of post humanity, Rubin defends a more modest vision of the future, one that takes seriously both the limitations and the inherent dignity of our given nature.
