It's interesting that they would claim that much SSA ancestry for all those ethnicities mentioned above. Especially for Mizrahis. I don't know how much SSA Ashkenazis and Sephardics have, the number would greatly vary but at least the admix calcs don't detect 3-5% SSA for Mizrahis. It would make more sense if Ashkenazis and Sephardics had more SSA but I doubt that even they have as much as 5% SSA. I believe even Samaritans don't score any SSA so why would Northern West Asian Mizrahis score any more than them? It's interesting...it would be good if someone puts the k12b results of these ancient southern levantines so we compare but at least some of this east african component might be ancient for some levantine groups :
