Around 200,000 years ago, a man--identical to us in all important respects--lived in Africa. Every person alive today is descended from him. How did this real-life Adam wind up father of us all? What happened to the descendants of other men who lived at the same time? And why, if modern humans share a single prehistoric ancestor, do we come in so many sizes, shapes, and races? Showing how the secrets about our ancestors are hidden in our genetic code, Spencer Wells reveals how developments in the cutting-edge science of population genetics have made it possible to create a family tree for the whole of humanity. We now know not only where our ancestors lived but who they fought, loved, and influenced. Informed by this new science, The Journey of Man is replete with astonishing information. Wells tells us that we can trace our origins back to a single Adam and Eve, but that Eve came first by some 80,000 years. We hear how the male Y-chromosome has been used to trace the spread of humanity from Africa into Eurasia, why differing racial types emerged when mountain ranges split population groups, and that the San Bushmen of the Kalahari have some of the oldest genetic markers in the world. We learn, finally with absolute certainty, that Neanderthals are not our ancestors and that the entire genetic diversity of Native Americans can be accounted for by just ten individuals. It is an enthralling, epic tour through the history and development of early humankind--as well as an accessible look at the analysis of human genetics that is giving us definitive answers to questions we have asked for centuries, questions now more compelling than ever.

Ten thousand years ago, our species made a radical shift in its way of life: We became farmers rather than hunter-gatherers. Although this decision propelled us into the modern world, renowned geneticist and anthropologist Spencer Wells demonstrates that such a dramatic change in lifestyle had a downside that we’re only now beginning to recognize. Growing grain crops ultimately made humans more sedentary and unhealthy and made the planet more crowded. The expanding population and the need to apportion limited resources created hierarchies and inequalities. Freedom of movement was replaced by a pressure to work that is the forebear of the anxiety millions feel today. Spencer Wells offers a hopeful prescription for altering a life to which we were always ill-suited. Pandora’s Seed is an eye-opening book for anyone fascinated by the past and concerned about the future.

From Graham Hancock, bestselling author of Fingerprints of the Gods, comes a mesmerizing book that takes us on a captivating underwater voyage to find the ruins of a lost civilization that’s been hidden for thousands of years beneath the world’s oceans. While Graham Hancock is no stranger to stirring up heated controversy among scientific experts, his books and television documentaries have intrigued millions of people around the world and influenced many to rethink their views about the origins of human civilization. Now he returns with an explosive new work of archaeological detection. In Underworld, Hancock continues his remarkable quest underwater, where, according to almost a thousand ancient myths from every part of the globe, the ruins of a lost civilization, obliterated in a universal flood, are to be found. Guided by cutting-edge science and the latest archaeological scholarship, Hancock begins his mission to discover the truth about these myths and examines the mystery at the end of the last Ice Age. As the glaciers melted between 17,000 and 7,000 years ago, sea levels rose and more than 15 million square miles of habitable land were submerged underwater, resulting in a radical change to the Earth’s shape and the conditions in which people could live. Using the latest computer techniques to map the world’s changing coastlines, Hancock finds astonishing correspondences with the ancient flood myths. Filled with thrilling accounts of his own participation in dives off the coast of Japan, as well as in the Mediterranean, the Atlantic, and the Arabian Sea, we watch as Hancock discovers underwater ruins exactly where the myths say they should be—sunken kingdoms that archaeologists never thought existed. Fans of Hancock’s previous adventures will find themselves immersed in Underworld, a provocative book that provides both compelling hard evidence for a fascinating, forgotten episode in human history and a completely new explanation for the origins of civilization as we know it.

Alice Roberts has been travelling the world - from Ethiopian desert to Malay peninsula and from Russian steppes to Amazon basin - in order to understand the challenges that early humans faced as they tried to settle continents. On her travels she has witnessed some of the daunting and brutal challenges our ancestors had to face: mountains, deserts, oceans, changing climates, terrifying giant beasts and volcanoes. But she discovers that perhaps the most serious threat of all came from other humans. When our ancestors set out from Africa there were already two other species of human on the planet: Neanderthal in Europe and Homo erectus in Asia. Both (contrary to popular perception) were intelligent, adept at making tools and weapons and were long adapted to their environments. So, Alice asks, why did only Homo sapiens survive? Part detective story, part travelogue, and drawing on the latest genetic and archaeological discoveries, Alice examines how our ancestors evolved physically in response to these challenges, finding out how our colour, shape, size, diet, disease resistance and even athletic ability have been shaped by the range of environments that our ancestors had to survive. She also relates how astonishingly closely related we all are. As a lecturer in Anatomy at Bristol University, Alice Roberts is eminently qualified to write this book. As a talented artist, she is perfectly qualified to illustrate it, and dotted throughout this lively book are many of the sketches and photographs from her travels.

"A lucid, thought-provoking account of the case for 'nature' as a determinant of personality." —Peter D. Kramer, Author of Listening to Prozac and Should You Leave? Nowhere is the nature-nuture controversy being more arduously tested than in the labs of world-renowned molecular scientist Dean Hamer, whose cutting-edge research has indisputably linked specific genes to behavioral traits, such as anxiety, thrill-seeking, and homosexuality. The culmination of that research os this provocative book, Living with Our Genes. In it, Dr. Hamer reveals that much of our behavior—how much we eat and weigh, whether we drink or use drugs, how often we have sex—is heavily influenced by genes. His findings help explain why one brother becomes a Wall Street trader, while his sibling remains content as a librarian, or why some people like to bungee-jump, while others prefer Scrabble. Dr. Hamer also sheds light on some of the most compelling and vexing aspects of personality, such as shyness, aggression, depression, and intelligence. In the tradition of the bestselling book Listening to Prozac, Living with Our Genes is the first comprehensive investigation of the crucial link between our DNA and our behavior. "Compulsive reading, reminiscent of Jared Diamond, froma scientsit who knows his stuff and communicates it well." —Kirkus Reviews "A pioneer in the field of molecular psychology, Hamer is exploring the role genes play in governing the very core of our individuality. Accessible...provocative." —Time "Absolutely terrific! I couldn't put it down." —Professor Robert Plomin, Social, Genetic & Developmental Psychiatry Research Center, Institute of Psychiatry

Until just a few years ago, we knew surprisingly little about the 150,000 or so years of human existence before the advent of writing. Some of the most momentous events in our past - including our origins, our migrations across the globe, and our acquisition of language - were veiled in the uncertainty of 'prehistory'. That veil is being lifted at last by geneticists and other scientists. Mapping Human History is nothing less than an astonishing 'history of prehistory'. Steve Olson travelled through four continents to gather insights into the development of humans and our expansion throughout the world. He describes, for example, new thinking about how centres of agriculture sprang up among disparate foraging societies at roughly the same time. He tells why most of us can claim Julius Caesar and Confucius among our forebears. He pinpoints why the ways in which the story of the Jewish people jibes with, and diverges from, biblical accounts. And using very recent genetic findings, he explodes the myth that human races are a biological reality.

Is our nature—as individuals, as a species—determined by our evolution and encoded in our genes? If we unravel the protein sequences of our DNA, will we gain the power to cure all of our physiological and psychological afflictions and even to solve the problems of our society? Today biologists—especially geneticists—are proposing answers to questions that have long been asked by philosophy or faith or the social sciences. Their work carries the weight of scientific authority and attracts widespread public attention, but it is often based on what the renowned evolutionary biologist Richard Lewontin identifies as a highly reductive misconception: "the pervasive error that confuses the genetic state of an organism with its total physical and psychic nature as a human being." In these nine essays covering the history of modern biology from Darwin to Dolly the sheep, all of which were originally published in The New York Review of Books, Lewontin combines sharp criticisms of overreaching scientific claims with lucid expositions of the exact state of current scientific knowledge—not only what we do know, but what we don't and maybe won't anytime soon. Among the subjects he discusses are heredity and natural selection, evolutionary psychology and altruism, nineteenth-century naturalist novels, sex surveys, cloning, and the Human Genome Project. In each case he casts an ever-vigilant and deflationary eye on the temptation to look to biology for explanations of everything we want to know about our physical, mental, and social lives. These essays—several of them updated with epilogues that take account of scientific developments since they were first written—are an indispensable guide to the most controversial issues in the life sciences today. The second edition of this collection includes new essays on genetically modified food and the completion of the Human Genome Project. It is an indispensable guide to the most controversial issues in the life sciences today.
