In fact the currently accepted history of life on Earth is flawed and out of date. Now two pioneering scientists, one already an award-winning popular author, deliver an eye-opening narrative that synthesizes a generation's worth of insights from new research.Writing with zest, humor, and clarity, Ward and Kirschvink show that many of our long-held beliefs about the history of life are wrong. Three central themes emerge from the narrative. First, the development of life was not a stately, gradual process: Catastrophe, argue Ward and Kirschvink, shaped life's history more than all other forces combined-from notorious events like the sudden extinction of dinosaurs to recently discovered ones like "Snowball Earth" and the "Great Oxygenation Event." One startling possibility: that life arrived on Earth from Mars. Second, life consists of carbon, but three other molecules have determined how it evolved: oxygen, carbon dioxide, and hydrogen sulfide are carbon's silent partners. Third, ever since Darwin we have thought of evolution in terms of species. Yet it is the evolution of ecosystems-from deep-ocean vents to rainforests-that has formed the living world as we know it.Drawing on their years of experience in paleontology, biology, chemistry, and astrobiology, Ward and Kirschvink tell a story of life on Earth that is at once too fabulous to imagine and too familiar to dismiss. And in a provocative coda, they assemble discoveries from the latest cutting-edge research to imagine how the history of life might unfold deep into the future.

    No bodies of water can compare to them. One of them, Superior, is the largest lake on earth, and the five lakes together contain a fifth of the world's supply of standing fresh water. Their ten thousand miles of shoreline bound eight states and a Canadian province and are longer than the entire Atlantic and Pacific coasts of the United States. Their surface area of 95,000 square miles is greater than New York, New Jersey, Connecticut, Massachusetts, Vermont, New Hampshire, and Rhode Island combined. People who have never visited them -- who have never seen a squall roar across Superior or the horizon stretch unbroken across Michigan or Huron -- have no idea how big they are. They are so vast that they dominate much of the geography, climate, and history of North America. In one way or another, they affect the lives of tens of millions of people.The Living Great Lakes is the most complete book ever written about the history, nature, and science of these remarkable lakes at the heart of North America. From the geological forces that formed them to the industrial atrocities that nearly destroyed them, to the greatest environmental success stories of our time, the lakes are portrayed in all their complexity. The book, however, is much more than just history. It is also the story of the lakes as told by biologists, fishermen, sailors, and others whom the author grew to know while traveling with them on boats and hiking with them on beaches and islands.The book is also the story of a personal journey. It is the narrative of a six-week voyage through the lakes and beyond as a crewmember on a tallmasted schooner, and a memoir of a lifetime spent on and near the lakes. Through storms and fog, on remote shores and city waterfronts, the author explores the five Great Lakes in all seasons and moods and discovers that they and their connecting waters -- including the Erie Canal, the Hudson River, and the East Coast from New York to Maine -- offer a surprising and bountiful view of America. The result is a meditation on nature and our place in the world, a discussion and cautionary tale about the future of water resources, and a celebration of a place that is both fragile and robust, diverse, rich in history and wildlife, often misunderstood, and worthy of our attention.

    Radiometric dating of nearby rocks indicated the skeleton, classified as Ardipithecus ramidus, was 4.4 million years old, more than a million years older than "Lucy," then the oldest known human ancestor. The findings challenged many assumptions about human evolution--how we started walking upright, how we evolved our nimble hands, and, most significantly, whether we were descended from an ancestor that resembled today's chimpanzee--and repudiated a half-century of paleoanthropological orthodoxy.Fossil Men is the first full-length exploration of Ardi, the fossil men who found her, and her impact on what we know about the origins of the human species. It is a scientific detective story played out in anatomy and the natural history of the human body. Kermit Pattison brings into focus a cast of eccentric, obsessive scientists, including one of the world's greatest fossil hunters, Tim White--an exacting and unforgiving fossil hunter whose virtuoso skills in the field were matched only by his propensity for making enemies; Gen Suwa, a Japanese savant who sometimes didn't bother going home at night to devote more hours to science; Owen Lovejoy, a onetime creationist-turned-paleoanthropologist; Berhane Asfaw, who survived imprisonment and torture to become Ethiopia's most senior paleoanthropologist and who fought for African scientists to gain equal footing in the study of human origins; and the Leakeys, for decades the most famous family in paloanthropology.An intriguing tale of scientific discovery, obsession and rivalry that moves from the sun-baked desert of Africa and a nation caught in a brutal civil war, to modern high-tech labs and academic lecture halls, Fossil Men is popular science at its best, and a must read for fans of Jared Diamond, Richard Dawkins, and Edward O. Wilson.
