Hi Obed, What an interesting finding. Are you aware of this paper? "Ancient Ethiopian genome reveals extensive Eurasian admixture throughout the African continent" http://www.sciencemag.org/content/350/6262/820 Although I appreciate your thinking of our work, it seems just as likely to me that you have found traces of the Neandertal DNA that was included in the back-migration to Africa from the Mediterranean-Middle Eastern region, several thousand years ago. I hope we'll all continue to investigate and learn more about this question! Bonnie -- *Farther Back We All Connect*
