Around 60,000 years ago, a man—genetically identical to us—lived in Africa. Every person alive today is descended from him. How did this real-life Adam wind up as the 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? Examining the hidden secrets of human evolution in our genetic code, Spencer Wells reveals how developments in the revolutionary science of population genetics have made it possible to create a family tree for the whole of humanity. Replete with marvelous anecdotes and remarkable information, from the truth about the real Adam and Eve to the way differing racial types emerged, The Journey of Man is an enthralling, epic tour through the history and development of early humankind.

Around 60,000 years ago, a man walked the soil of Africa. Every person alive today is descended from him. How did he come to be the father to all of us - a real-life Adam? The answer, as Spencer Wells shows, is hidden in our genetic code. It enables us not just to discover where our ancestors lived (and who they may have fought, loved and learned from) but to create a family tree for the whole of humanity. The Journey of Man reveals, among other things, how we evolved into such a huge variety of sizes, shapes and races; how humanity spread from Africa to the far corners of the earth; and who the real Adam and Eve were. This enthralling tour through our shared history provides answers to questions which, in an age obsessed by who we are and where we really came from, are more compelling than ever.

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.

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. From the Hardcover edition.

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.

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.

The history of life on Earth is dominated by extinction events so numerous that over 99.9% of the species ever to have existed are gone forever. If animals could talk, we would ask them to recall their own ancestries, in particular the secrets as to how they avoided almost inevitable annihilation in the face of daily assaults by predators, climactic cataclysms, deadly infections and innate diseases. In Tears of the Cheetah, medical geneticist and conservationist Stephen J. O'Brien narrates fast-moving science adventure stories that explore the mysteries of survival among the earth's most endangered and beloved wildlife. Here we uncover the secret histories of exotic species such as Indonesian orangutans, humpback whales, and the imperiled cheetah-the world's fastest animal which nonetheless cannot escape its own genetic weaknesses. Among these genetic detective stories we also discover how the Serengeti lions have lived with FIV (the feline version of HIV), where giant pandas really come from, how bold genetic action pulled the Florida panther from the edge of extinction, how the survivors of the medieval Black Death passed on a genetic gift to their descendents, and how mapping the genome of the domestic cat solved a murder case in Canada. With each riveting account of animal resilience and adaptation, a remarkable parallel in human medicine is drawn, adding yet another rationale for species conservation-mining their genomes for cures to our own fatal diseases. Tears of the Cheetah offers a fascinating glimpse of the insight gained when geneticists venutre into the wild.

Evidence from paleoanthropology and genetics has consistently shown that our species originated in Africa. Recent results from the Y-chromosome confirm this, but further posit that all modern humans were still living in Africa 60,000 years ago. The case for a recent 'African exodus' will be discussed, with supporting evidence drawn from DNA polymorphisms, paleoclimatology and archaeology.
