New Study Maps the Genetic History of People of African Descent

A research team led by Sarah Tishkoff, the David and Lyn Silfen University Associate Professor at the University of Pennsylvania School of Medicine, has published the largest database of genetic information on Africans and African Americans. The new genetic library holds data on more than 4 million people of African descent.

But the descriptions will contain information on the locality of the actual documents and how researchers can gain access to them.

The genetic data on African Americans shows that 71 percent have bloodlines that can be traced to western Africa. Thirteen percent of all African Americans have predominantly European roots. In other words, 13 percent of all African Americans are more than half white.
