The largest genetic study of African populations reveals a greater diversity among the continent's cultural groups than previously known, scientists say. The study also offers insight into the origins of modern humans and the ancestry of African-Americans, researchers said in an April 29 teleconference and in a paper posted online April 30 in Science.
Until now, most genetic surveys of this type have used data from just a few African groups assumed to reflect Africa's genetic diversity. But the new research shows that "no single African population is representative of the diversity of the continent," says study coauthor Sarah Tishkoff of the University of ...
