If you’ve enjoyed the recent  PBS Ancestry series Finding your roots with Henry Louis Gates Jr, you’ll be fascinated with  DNA USA : a genetic portrait of America.

Oxford professor Bryan Sykes has written a readable and engaging account of human population genetics in the setting of a road (and train) trip across one of the world’s most genetically diverse countries, the United States.  Using   DNA information gleaned from contacts, Sykes explains issues of genetic inheritance, summarizing current research, including his own role investigating genetics of Britain’s historic ethnic groups detailed in Saxons, Vikings and Celts.

 More information about human population genetics can be found at Deep ancestry : inside the Genographic Project by Spencer Wells, and Sykes’ The Seven Daughters of Eve.
