Deep ancestry : inside the Genographic Project / Spencer Wells.

Science tells us we're all related--one vast family sharing a common ancestor who lived in Africa 60,000 years ago. But countless questions remain about our great journey from the birthplace of Homo sapiens. How and when did we end up where we are? Why do we display such a wide range of colors and features? The fossil record offers some answers, but new research reveals many more, since our DNA carries a chronicle of our species and its migrations. This book translates complicated concepts into accessible language and explains how each individual's DNA contributes another piece to the puzzle. It takes readers inside the Genographic Project, the landmark study now assembling the world's largest collection of DNA samples and employing the latest in testing technology and computer analysis to examine hundreds of thousands of genetic profiles from all over the globe, showing how universal our human heritage really is.--From publisher description.
