    • Tishkoff and her colleagues analyzed the genetic information of more than 3,000 people from 121 different populations of self-identified ethnic groups scattered throughout Africa.

    • The researchers found that the genetic sequences were highly diverse from one population to the next. Because modern humans originated in Africa, there has been more time for changes to accumulate in the African DNA sequences than there has been in other parts of the world, Tishkoff says.

      It turns out that the San bushmen of southern Africa have the most distinct, and therefore oldest, genetic sequences, the team reports.
