The sea contains millions of species of animals and plants, but we have identified only a few thousand of them. The sea controls our planet's climate, but we do not really understand how. The sea is still the frontier, and yet it seems so familiar that we sometimes forget how little we know about it. Just as we are poised on the verge of exploiting the sea on an unprecedented scale—mining it, fertilizing it, fishing it out—this book reminds us of how much we have yet to learn. More than that, it chronicles the knowledge explosion that has transformed our view of the sea in just the past few decades, and made it a far more interesting and accessible place. From the Big Bang to that far-off future time, two billion years from now, when our planet will be a waterless rock; from the lush crowds of life at seafloor hot springs to the invisible, jewel-like plants that float at the sea surface; from the restless shifting of the tectonic plates to the majestic sweep of the ocean currents, Kunzig's clear and lyrical prose transports us to the ends of the Earth.Originally published in hardcover as The Restless Sea.

     Where do clouds come from? Why do they look the way they do? And why have they captured the imagination of timeless artists, Romantic poets, and every kid who's ever held a crayon? Journalist and lifelong sky watcher Gavin Pretor-Pinney reveals everything there is to know about clouds, from history and science to art and pop culture. Cumulus, nimbostratus, and the dramatic and seemingly surfable Morning Glory cloud are just a few of the varieties explored in this smart, witty, and eclectic tour through the skies. Generously illustrated with striking photographs and line drawings featuring everything from classical paintings to lava lamps, children's drawings, and Roman coins, The Cloudspotter's Guide will have science and history buffs, weather watchers, and the just plain curious floating on cloud nine.

    The title refers to the physiographic province of the United States that reaches from eastern Utah to eastern California, a silent world of austere beauty, of hundreds of discrete high mountain ranges that are green with junipers and often white with snow. The terrain becomes the setting for a lyrical evocation of the science of geology, with important digressions into the plate-tectonics revolution and the history of the geologic time scale.

    Melting glaciers, warming oceans, droughts-it's clear that today's world is getting hotter. But while we know the agony of a sunburn or the comfort of our winter heaters, do we really understand heat? A bestselling scientist and nature writer who goes to any extreme to uncover the answers, Bill Streever sets off to find out what heat really means. Let him be your guide and you'll firewalk across hot coals and sweat it out in Death Valley, experience intense fever and fire, learn about the invention of matches and the chemistry of cooking, drink crude oil, and explore thermonuclear weapons and the hottest moment of all time-the big bang. Written in Streever's signature spare and refreshing prose, Heat is an adventurous personal narrative that leaves readers with a new vision of an everyday experience-how heat works, its history, and its relationship to daily life.

    Their discoveries have spawned a host of new questions: Should chimpanzees be included as a human species? Was it the physical difficulty of human childbirth that encouraged the development of social groups in early human species? Did humans and Neanderthals interbreed? Why did humans supplant Neanderthals in the end? In answering such questions, Smithsonian Intimate Guide to Human Origins sheds new light on one of the most important questions of all: What makes us human?

    But countless questions remain about our great journey from the birthplace of Homo sapiens to the ends of the Earth. How did we end up where we are? When did we get there? Why do we display such a wide range of colors and features? The fossil record offers some answers, but exciting new genetic research reveals many more, since our DNA carries a complete chronicle of our species and its migrations. In Deep Ancestry, scientist and explorer Spencer Wells shows how tiny genetic changes add up over time into a fascinating story. Using scores of real-life examples, helpful analogies, and detailed diagrams and illustrations, he translates complicated concepts into accessible language and explains exactly how each and every individual's DNA contributes another piece to the jigsaw puzzle of human history. The book takes readers inside the Genographic Project, the landmark study now assembling the world's largest collection of population genetic DNA samples and employing the latest in testing technology and computer analysis to examine hundreds of thousands of genetic profiles from all over the globe. Traveling backward through time from today's scattered billions to the handful of early humans who are ancestors to us all, Deep Ancestry shows how universal our human heritage really is. It combines sophisticated science with our compelling interest in family history and ethnic identity—and transcends humankind's shallow distinctions and superficial differences to touch the depths of our common origins.

    In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age. Part paleontological adventure and part memoir, Twilight of the Mammoths presents in detail internationally renowned paleoecologist Paul Martin's widely discussed and debated "overkill" hypothesis to explain these mysterious megafauna extinctions. Taking us from Rampart Cave in the Grand Canyon, where he finds himself "chest deep in sloth dung," to other important fossil sites in Arizona and Chile, Martin's engaging book, written for a wide audience, uncovers our rich evolutionary legacy and shows why he has come to believe that the earliest Americans literally hunted these animals to death.As he discusses the discoveries that brought him to this hypothesis, Martin relates many colorful stories and gives a rich overview of the field of paleontology as well as his own fascinating career. He explores the ramifications of the overkill hypothesis for similar extinctions worldwide and examines other explanations for the extinctions, including climate change. Martin's visionary thinking about our missing megafauna offers inspiration and a challenge for today's conservation efforts as he speculates on what we might do to remedy this situation—both in our thinking about what is "natural" and in the natural world itself.

    That evidence, he argues, shows that 700 million years ago the Earth did indeed freeze over completely, becoming a giant “snowball,” in the worst climatic catastrophe in history. Even more startling is his assertion that, instead of ending life on Earth, this global deep freeze was the trigger for the Cambrian Explosion, the hitherto unexplained moment in geological time when a glorious profusion of complex life forms first emerged from the primordial ooze.In a story full of intellectual intrigue, we follow the irascible but brilliant Hoffman and a supporting cast of intrepid geologists as they scour the planet, uncovering clue after surprising clue. We travel to a primeval lagoon at Shark Bay in western Australia, where dolphins cavort with swimmers every morning at seven and “living rocks” sprout out of the water like broccoli heads; to the desolate and forbidding ice fields of a tiny Arctic archipelago seven hundred miles north of Norway; to the surprising fossil beds that decorate Newfoundland’s foggy and windswept coastline; and on to the superheated salt pans of California’s Death Valley.Through the contours of these rich and varied landscapes Walker teaches us to read the traces of geological time with expert eyes, and we marvel at the stunning feats of resilience and renewal our remarkable planet is capable of. Snowball Earth is science writing at its most gripping and enlightening.

    In Tales from the Underground, Cornell ecologist David Wolfe takes us on a tour through current scientific knowledge of the subterranean world. We follow the progress of discovery from Charles Darwin's experiments with earthworms, to Lewis and Clark's first encounter with prairie dogs, to the use of new genetic tools that are revealing an astonishingly rich ecosystem beneath our feet. Wolfe plunges us deep into the earth's rocky crust, where life may have begun-a world devoid of oxygen and light but safe from asteroid bombardment. Primitive microbes found there are turning our notion of the evolutionary tree of life on its head: amazingly, they represent perhaps a full third of earth's genetic diversity. As Wolfe explains, creatures of the soil can work for us, by providing important pharmaceuticals and recycling the essential elements of life, or against us, by spreading disease and contributing to global climate change. The future of our species may well depend on how we manage our living soil resources. Tales from the Underground will forever alter our appreciation of the natural world around-and beneath-us.

    Prosek travels the globe to tell the story of the eel--from New York to New Zealand; from Europe to Japan and the small island of Pohnpei in Micronesia, where freshwater eels are worshipped by members of the eel clan.

    Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe--descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished. Ever since the first Neanderthal bones were identified in 1856, scientists have been vexed by the question, why did modern humans survive while their evolutionary cousins went extinct?The Invaders musters compelling evidence to show that the major factor in the Neanderthals' demise was direct competition with newly arriving humans. Drawing on insights from the field of invasion biology, which predicts that the species ecologically closest to the invasive predator will face the greatest competition, Pat Shipman traces the devastating impact of a growing human population: reduction of Neanderthals' geographic range, isolation into small groups, and loss of genetic diversity.But modern humans were not the only invaders who competed with Neanderthals for big game. Shipman reveals fascinating confirmation of humans' partnership with the first domesticated wolf-dogs soon after Neanderthals first began to disappear. This alliance between two predator species, she hypothesizes, made possible an unprecedented degree of success in hunting large Ice Age mammals--a distinct and ultimately decisive advantage for humans over Neanderthals at a time when climate change made both groups vulnerable.

    One midsummer week over sixty years later, Olivia Laing walked Woolf's river from source to sea. The result is a passionate investigation into how history resides in a landscape - and how ghosts never quite leave the places they love. Along the way, Laing explores the roles rivers play in human lives, tracing their intricate flow through literature and mythology alike. To the River excavates all sorts of stories from the Ouse's marshy banks, from the brutal Barons' War of the thirteenth century to the 'Dinosaur Hunters', the nineteenth-century amateur naturalists who first cracked the fossil code. Central among these ghosts is, of course, Virginia Woolf herself: her life, her writing and her watery death. Woolf is the most constant companion on Laing's journey, and To the River can be read in part as a biography of this extraordinary English writer, refracted back through the river she loved. But other writers float through these pages too - among them Iris Murdoch, Shakespeare, Homer and Kenneth Grahame, author of the riverside classic The Wind in the Willows. The result is a wonderfully discursive read - which interweaves biography, history, nature writing and memoir, driven by Laing's deep understanding of science and cultural history. It's a beautiful, lyrical work that marks the arrival of a major new writer.

    An exhilarating account of Sapolsky’s twenty-one-year study of a troop of rambunctious baboons in Kenya, A Primate’s Memoir interweaves serious scientific observations with wry commentary about the challenges and pleasures of living in the wilds of the Serengeti — for man and beast alike. Over two decades, Sapolsky survives culinary atrocities, gunpoint encounters, and a surreal kidnapping, while witnessing the encroachment of the tourist mentality on the farthest vestiges of unspoiled Africa. As he conducts unprecedented physiological research on wild primates, he becomes evermore enamored of his subjects — unique and compelling characters in their own right — and he returns to them summer after summer, until tragedy finally prevents him.By turns hilarious and poignant, A Primate’s Memoir is a magnum opus from one of our foremost science writers.

    Darwin wondered why these birds were confined to remote islands at the tip of South America, sensing a larger story, but he set this mystery aside and never returned to it. Almost two hundred years later, Jonathan Meiburg takes up this chase. He takes us through South America, from the fog-bound coasts of Tierra del Fuego to the tropical forests of Guyana, in search of these birds: striated caracaras, which still exist, though they're very rare. He reveals the wild, fascinating story of their history, origins, and possible futures. And along the way, he draws us into the life and work of William Henry Hudson, the Victorian writer and naturalist who championed caracaras as an unsung wonder of the natural world, and to falconry parks in the English countryside, where captive caracaras perform incredible feats of memory and problem-solving. A Most Remarkable Creature is a hybrid of science writing, travelogue, and biography, as generous and accessible as it is sophisticated, and absolutely riveting.

    The fascinating story of how a harsh terrain that resembled modern Antarctica has been transformed gradually into the forests, grasslands, and wetlands we know today.
