Two leading scientific journals "Science" and "Nature" have both published studies last week on studies on human migration based on DNA. Both research groups relied on DNA from blood samples collected by anthropologists around the world as part of the Human Genome Diversity Project, a controversial effort from the mid-1990s to gather genetic specimens from thousands of populations, including many indigenous tribes. "Instead of saying a particular person's genome is from Africa, this kind of data allows us to say which part of Africa they were from," said Andrew Singleton, chief of the molecular genetics section at the National Institute on Aging in Bethesda, Md., and senior author of the Nature report.
