Dna Usa : A Genetic Portrait of America

Bryan Sykes, one of the world s leading geneticists and best-selling author of The Seven Daughters of Eve, sets his sights on America, one of the most genetically variegated countries in the world. Sykes embarks on a road trip DNA testing kit in tow interviewing genealogists, anthropologists, and everyday Americans, tracing America s history along a double helix that stretches from the last Ice Age to the present day. What emerges is an unprecedented look into America s genetic mosaic that challenges the very notion of how we perceive race and what it means to be an American."
