Most Europeans, for example, are descended from this relatively small group, and therefore reflect a rather uniform genetic makeup.
European DNA therefore "represents only a subset of genetic diversity," Myers said. The biggest repository of genetic diversity remained on the ark of the initial continent, Africa.
When European and American slave traders landed on the shores of Africa, stealing away people for forced labor in far-away lands, this resulted in a new genetic diversity among the descendents of slaves, many of which also have European blood.
The fact of this genetic mixing, which occurred in a clear time window of about 200 years, set up the unique conditions that the geneticists used in their work.
According to Rolf Horstmann, who teaches molecular medicine at the Bernhard Nocht Institute for Tropical Medicine in Hamburg, the research highlights the genetic differences between African and European populations."
This is going to be a good one. I simply cannot wait for the negro perspective.
