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
