DNA U.S.A.

We sit down with Oxford professor Bryan Sikes whose new book. "DNA U.S.A." explores the complicated genetic melting pot of America. The findings are fascinating, southwestern Spanish Catholics with Jewish genes, African DNA in southern whites. Though we are all born with surnames, Sykes says, "those names fragment and mutate with far more regularity than the DNA we inherit”
