    For ten years, Genographic Project scientists have explored and explained how patterns in our DNA show evidence of migration out of Africa and across the globe. But new research shows that eventually some of our ancient ancestors also moved back.
    To uncover evidence of an ancient migration pattern, scientists studied the DNA of a specific haplogroup (O2a1). Geneticists who conducted the new research say they studied the O2a1 haplogroup because “it accounts for almost 15 percent of Indian male lineages and 58 percent of male lineages from Southeast Asia,” among other reasons. What about the women? What percentage of Southeast Asian women belong to the O2a1 haplogroup?
    They don’t. Like all the haplogroups shown on the map above, O2a1 is a Y-chromosome haplogroup. That means the DNA sequences (haplotypes) that link this specific group are found on the Y chromosome.
