> >in 2011, moorjani et al. detected 3%5% sub-saharan african ancestry in all eight of the diverse jewish populations (ashkenazi jews, syrian jews, iranian jews, iraqi jews, greek jews, turkish jews, italian jews) that they analyzed. the timing of this african admixture among all jewish populations was identical. the exact date was not determined, but it was estimated to have taken place between 1,600 and 3,400 years ago. although african admixture was determined among south europeans and near eastern population too, this admixture was found to be younger compared to the jewish populations. this findings the authors explained as evidence regarding common origin of these 8 main jewish groups. "it is intriguing that the mizrahi irani and iraqi jewswho are thought to descend at least in part from jews who were exiled to babylon about 2,600 years ago share the signal of african admixture. a parsimonious explanation for these observations is that they reflect a history in which many of the jewish groups descend from a common ancestral population which was itself admixed with africans, prior to the beginning of the jewish diaspora that occurred in 8th to 6th century bc" the authors concluded
