Review by Tina Hesman Saey
A human geneticist has dipped his DNA testing kit into the great melting pot, exploring the genetic history, genealogy and anthropology of Americans. Sykes travels across the country meeting ordinary people and creating portraits of their chromosomes that reflect from whence their ancestors hailed. All the volunteers are given pseudonyms drawn from Hollywood movies, but the stories of their heritage are engagingly real.
As the author of The Seven Daughters of Eve and other books, Sykes is an old hand at writing about genetics for the general public. His experience shows as he deftly introduces highly technical information in reader-friendly ways.
