Ultra-detailed study of human genetic variation released

That modern Homo sapiens emerged out of Africa at some point in time has quite a bit of evidence.  But what has remained uncertain was who these adventurous people were.  What area of Africa were they from?  How many of them were there?  And how did they spread out to populate the globe?

Researchers at the University of Michigan and at the National Institute on Aging conducted a detailed study of genetic variation in human populations, which can pinpoint a person’s genetic heritage to a specific population in a geographic region.  Results at this level of specificity mean that this information is 100 times more detailed than previous studies.
