Not only are we all descended from a common African 'Adam' and 'Eve', but what's more it can now be proved that all modern non-Africans sprang from a single exodus out of Africa, rather than peopling the earth in multiple waves of migration. In a brilliant synthesis of genetic, archaeological and climatic evidence, Stephen Oppenheimer reveals the story of how a group of no more than a few hundred souls crossed the mouth of the Red Sea some 80,000 years ago. The book follows their halting progress around the world - to the mammoth Steppe heartland of Asia and the now submerged continent of Beringia, and on to the last great unpeopled lands of the Americas. It is a revolutionary account that is both scholarly and entertaining, a remarkable picture of the kinship of all humans.
