Africans
Africans have more genetic variation than anyone else on Earth, according to a new study that helps narrow the location where humans first evolved, probably near the South Africa-Namibia border.

Native Americans had the least genetic diversity of all, indicating that part of the world was settled last. "Previously, we've been able to look at the genome and say, 'This part is from Africa, this is from Asia,'" explained Virginia research Andrew Singleton to Wired News.African
Nearly all genetic studies indicate greater diversity in African populations (Figure 1), which is consistent with an African origin of modern humans.
What races are most closely related
Abstract. Using gene frequency data for 62 protein loci and 23 blood group loci, we studied the genetic relationship of the three major races of man, Caucasoid, Negroid, and Mongoloid. Genetic distance data indicate that Caucasoid and Mongoloid are somewhat closer to each other than to Negroid.
