The Journey of Man: A Genetic Odyssey
Penguin Adult, 2003 M05 29 - 288 pages
Around 60,000 years ago, a man, identical to us in all important respects, walked the soil of Africa. Every man alive today is descended from him. How did he come to be father to all of us - a real-life Adam? And why do we come in such a huge variety of sizes, shapes, types and races if we all share a single prehistoric ancestor?
In this fascinating book, Spencer Wells shows how the truth about our ancestors is hidden in our genetic code, and reveals how developments in the cutting-edge science of population genetics have made it possible not just to discover where our ancestors lived (and who they may have fought, loved, learned from and influence) but to create a family tree for the whole of humanity.

Review: The Journey of Man: A Genetic OdysseyUser Review - Joe - Goodreads
Conclusion of Wells' work is that we're all descendants of a single man who lived in Africa about 20,000 years ago. And he is convincing! Very interesting book, with some genetic science thrown in to spice it up (but it doesn't get in the way). Read full review

The book presents a picture of man's migrations between 60,000 and 10,000 years ago. It is a companion book with the TV special and provides more background into the scientific rational of the study and its conclusions. It is presented in a manner quite understandable to the lay person. Read full review
