    The Old Egyptians samples coming up are Neolithic Levantinelike. And Neothic Levantines don't have anything we can call SSA.

    The model clearly shows that Natufians had a significant amount of SSA, and the studies I cited, as well as the one originally cited by BalkanKiwi discuss the ties between the Ancient Natufians, N. African groups, and pre-Omotic peoples in E. Africa, consistent with the spread of Y-DNA E. The reason that the BA Levant groups have less SSA is because of migration from Mesopotamia and the Northern Middle East as discussed in the Agranat-Tamir study. By the Israelite era, the Natufian component was very diluted and represented a minority of Levantine DNA while the majority was from the Mesopotamian migrations. This is discussed on many of the threads about Jews and Canaanites. Also, please see my results and the Samaritan average result which shows that we both have 2.8% African.

    Egypt circa Old Kingdom had no notable migration from Mesopotamia.

    Ok, but the Levant did, I was responding to your assertion that the Neolithic Levant had no SSA.

    One important point of contention on this thread has been whether the SSA in Western Jews derives from N. Africa and thus from Yoruba-like admixture or from a more Ancient E. African source. I took the G25 World K=8 calculator I previously used and instead of "African", I put in the following modern averages: Yoruba and Dinka. Here was the result:
    Anthro_Jewish_SSA.png
    As you can see, the Natufians have a significant amount of Dinka-like E. African, which comes out more diluted in the Israelite ABM sample from thousands of years later, due to Mesopotamian admixture. The Dinka goes from 14 to 3.4%, pretty consistent with the theory that modeling Israelites as Natufian vs some N. MENA source comes out to about 25% Natufian and 75% North MENA due to the migration I previously mentioned. I have slightly lower Dinka at 3.2%, probably due to European admixture in Ashkenazim, and the Samaritans have slightly higher Dinka (possibly due to minor mixing with Arabs over the past millennium) at 3.8%. This is fairly consistent with what we know about the genetic history of all these populations. One important point: there is no Yoruba/W. African admixture for me that could have been derived from N. Africa, rather all my SSA admixture shows up as Dinka/E. African.
