Does this mean that Mota-like people were demographically dominant in ancient Sudan?
I'm not exactly sure what to make of this as its simply a 2 way mix but when you use a group like PPNB it inflates Mota-like ancestry relative to what you would get if you used Natufian, if he used Natufian it would have been able to account for some of that Mota-like ancestry. But even then its suprising that they prefer Mota to Dinka which is pretty interesting tbh.
On the PCA he created the sample has a southern shift on the PC2 axis, which could indicate an excess Mota affinity relative to modern Horners.
He should run a model using Natufian and Dinka aswell as PPNB and KEN_LSA, I'm certain the Mota-like ancestry will plummet but if they really do score a lot of Mota-like whilst Dinka and Natufian is employed then yeah, Mota-like ancestry was more widespread in Sudan than previously assumed.
I've argued in other threads that Natufians have Mota-like ancestry that came from Paleolithic and/or Mesolithic Egypt, Paleolithic remains in Egypt often reveal very SSA shifted phenotypes with broad affinties to modern and MSA SSAs, so I think these remains will turn up very KEN_LSA/Mota. Natufian-like people may have admixed with Dinka-like groups aswell as these Mota/KEN_LSA types.

, do Khormusan count as part of the spectrum with mechtoid affinities?
