Most genetic variation is shared worldwide. It is only a small part of human genetic variation that is private to particular continents—Noah Rosenberg
“We’re all pretty much the same except, of course, for the little things that make us different,” writes David Brown of the Washington Post, reporting on the conclusions of three Human Genome Project studies published last week.

All three studies support the notion that modern human beings left East Africa, walked into Central Asia and then dispersed east and west to populate the globe. The studies confirmed that Africans have more diverse genes than people of other continents. In fact, genetic diversity declines the farther one’s ancestor’s travelled from Africa. One study found that Americans of European descent carry more damaging gene variants than African Americans… No doubt “a byproduct of Caucasians’ arduous march eastward to the shores of the Atlantic,” suggests Brown.
