A major audiobook 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.

At once an incredible adventure narrative and a penetrating biographical portrait, The River of Doubt is the true story of Theodore Roosevelt's harrowing exploration of one of the most dangerous rivers on earth.

The best-selling author of Truman and John Adams, David McCullough has written profiles of exceptional men and women past and present who have not only shaped the course of history or changed how we see the world but whose stories express much that is timeless about the human condition. Here are Alexander von Humboldt, whose epic explorations of South America surpassed the Lewis and Clark expedition; Harriet Beecher Stowe, "the little woman who made the big war”....

Alexander von Humboldt (1769-1859) was an intrepid explorer and the most famous scientist of his age. His restless life was packed with adventure and discovery, whether climbing the highest volcanoes in the world or racing through anthrax-infested Siberia. He came up with a radical vision of nature, that it was a complex and interconnected global force and did not exist for man's use alone. Ironically, his ideas have become so accepted and widespread that he has been nearly forgotten.

For millennia the location of the Nile River’s headwaters was shrouded in mystery. In the 19th century, there was a frenzy of interest in ancient Egypt. At the same time, European powers sent off waves of explorations intended to map the unknown corners of the globe—and extend their colonial empires.

Wilbur Smith has lived an incredible life of adventure, and now he shares the extraordinary true stories that have inspired his fiction. From being attacked by lions to close encounters with deadly reef sharks, from getting lost in the African bush without water to crawling the precarious tunnels of gold mines, from marlin fishing with Lee Marvin to near death from crash-landing a Cessna airplane, from brutal school days to redemption through writing and falling in love, Wilbur Smith tells us the intimate stories of his life that have been the raw material for his fiction.

Scientists often challenge conventional wisdom and spark debates that last for generations. But no scientist has fuelled more debate than Charles Darwin. To some he is the revolutionary 'father' of evolution. To others he is the perverse 'originator' of modern eugenics. In The Darwin Myth: The Life and Lies of Charles Darwin, author Benjamin Wiker brings these conflicting identities to light.

In 1994 Professor Bryan Sykes, a leading world authority on DNA and human evolution, was called in to examine the frozen remains of a man trapped in glacial ice in northern Italy. News of both the Ice Man's discovery and his age, which was put at over 5,000 years, fascinated scientists and newspapers throughout the world. But what made Sykes's story particularly revelatory was his successful identification of a genetic descendant of the Ice Man, a woman living in Great Britain today. How was Sykes able to locate a living relative?

Perhaps no American president is more associated with nature and wildlife than Theodore Roosevelt, a prodigious hunter and adventurer and an ardent conservationist. We think of Roosevelt as an original, yet in The Naturalist, Darrin Lunde shows how from his earliest days Roosevelt actively modeled himself in the proud tradition of museum naturalists - the men who pioneered a key branch of American biology through their desire to collect animal specimens and develop a taxonomy of the natural world.

The compelling story of the effect of Charles Darwin's book On the Origin of Species on a diverse group of American writers, abolitionists, and social reformers, including Henry David Thoreau and Bronson Alcott, in 1860.

Half of all species could disappear by the end of the century, and scientists now concede that most of America’s endangered animals will survive only if conservationists keep rigging the world around them in their favor. So Jon Mooallem ventures into the field, often taking his daughter with him, to move beyond childlike fascination and make those creatures feel more real. Wild Ones is a tour through our environmental moment and the eccentric cultural history of people and wild animals in America that inflects it.

Having worked on numerous high-profile genetic investigations, including one focused on the famed Iceman of the Italian Alps, Bryan Sykes has become a premier authority on human genetics. In DNA USA, Sykes examines the unique fabric of the population of the United States - one of the world’s most genetically variegated countries. His fascinating discoveries offer new insights into the biological profile of the great melting pot.

Frederick Law Olmsted is arguably the most important historical figure that the average American knows the least about. Best remembered for his landscape architecture, from New York's Central Park to Boston's Emerald Necklace to Stanford University's campus, Olmsted was also an influential journalist, early voice for the environment, and abolitionist credited with helping dissuade England from joining the South in the Civil War. This momentous career was shadowed by a tragic personal life, also fully portrayed here.

"Walden. Yesterday I came here to live." That entry from the journal of Henry David Thoreau, and the intellectual journey it began, would by themselves be enough to place Thoreau in the American pantheon. His attempt to "live deliberately" in a small woods at the edge of his hometown of Concord has been a touchstone for individualists and seekers since the publication of Walden in 1854. But there was much more to Thoreau than his brief experiment in living at Walden Pond.

The Galapagos were once known to the sailors and pirates who encountered them as Las Encantadas: the enchanted islands, home to exotic creatures and dramatic volcanic scenery. In The Galapagos, science writer Henry Nicholls offers a lively natural and human history of the archipelago, charting its evolution from deserted wilderness to scientific resource (made famous by Charles Darwin) and global ecotourism hot spot.

Just 150 years ago, most of our world was an unexplored wilderness. Our sense of its age was vastly off the mark. And what we believed to be the history of our own species consisted of fantastic myths and fairy tales; fossils, known for millennia, were seen as the bones of dragons and other imagined creatures. How did we learn so much so quickly? Remarkable Creatures celebrates the pioneers who replaced our fancies with the even more remarkable real story of how our world evolved.

Nine remarkable men produced inventions that changed the world. The printing press, the telephone, powered flight, recording and others have made the modern world what it is. But who were the men who had these ideas and made reality of them? As David Angus shows, they were very different - quiet, boisterous, confident, withdrawn - but all had a moment of vision allied to single-minded determination to battle through numerous prototypes and produced something that really worked. This is a fascinating account for younger listeners.

In December 1929, in a cave near Peking, a group of anthropologists and archaeologists that included a young French Jesuit priest named Pierre Teilhard de Chardin uncovered a prehuman skull. The find quickly became known around the world as Peking Man and was acclaimed as the missing link between erect hunting apes and our Cro-Magnon ancestors. It also became a provocative piece of evidence in the roiling debate over creationism versus evolution.

In 1856 Paul Du Chaillu marched into the equatorial wilderness of West Africa determined to bag an animal that, according to legend, was nothing short of a monster. When he emerged three years later, the summation of his efforts only hinted at what he'd experienced in one of the most dangerous regions on earth. Armed with an astonishing collection of zoological specimens, Du Chaillu leapt from the physical challenges of the jungle straight into the center of the biggest issues of the time.

When Dr. David Hosack tilled the country's first botanical garden in the Manhattan soil more than 200 years ago, he didn't just dramatically alter the New York landscape; he left a monumental legacy of advocacy for public health and wide-ranging support for the sciences. In melodic prose, historian Victoria Johnson eloquently chronicles Hosack's tireless career to reveal the breadth of his impact. The result is a lush portrait of the man who gave voice to a new, deeply American understanding of the powers and perils of nature.

In this hugely entertaining sequel to the New York Times best-selling memoir An Appetite for Wonder, Richard Dawkins delves deeply into his intellectual life spent kick-starting new conversations about science, culture, and religion and writing yet another of the most audacious and widely read books of the 20th century - The God Delusion.

From well-known nature and adventure writer Dan Koeppel, whose work has appeared in Audubon and National Geographic Adventure, comes this true story of one bird watcher's incredible achievements.

Rosemary and Peter Grant and those assisting them have spend 20 years on Daphne Major, an island in the Galapagos, studying natural selection. They recognize each individual bird on the island, when there are 400 at the time of the author's visit or when there are over a thousand. They have observed about 20 generations of finches - continuously.Jonathan Weiner follows these scientists as they watch Darwin's finches and come up with a new understanding of life itself.

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.

When young Joseph Banks stepped onto a Tahitian beach in 1769, he hoped to discover Paradise. Inspired by the scientific ferment sweeping through Britain, the botanist had sailed with Captain Cook in search of new worlds. Other voyages of discovery—astronomical, chemical, poetical, philosophical—swiftly follow in Richard Holmes's thrilling evocation of the second scientific revolution.

No cloistered don, this tall, married Englishman was a freethinking intellectual, who practiced nudism and was devoted to a quirky brand of folk dancing. In 1937, while working as a biochemist at Cambridge University, he instantly fell in love with a visiting Chinese student, with whom he began a lifelong affair. He soon became fascinated with China, and his mistress swiftly persuaded the ever-enthusiastic Needham to travel to her home country, where he embarked on a series of extraordinary expeditions to the farthest frontiers of this ancient empire.
