When ancestral humans walked out of Africa tens of thousands of years ago, Drosophila melanogaster fruit flies came along with them. Now the fruit flies, widely used for genetics research, are returning to Africa and establishing new populations alongside flies that never left - offering new insights into the forces that shape genetic variation. That's one of the findings from two new papers published this month by researchers at the University of California, Davis, and their colleagues that describe the genomes of almost 200 strains of the tiny flies...
