I'm also interested in this. If it isn't too far off-topic, have you taken a look at the Taforalt paper? The ADMIXTURE analysis suggests that the African admixture in Natufian, Iran_Hotu/Iran_Neo and so forth is related to a component that is modal in the Hadza. A very unlikely source, but it looks quite solid. It's even more pronounced in the Taforalt samples and still very significant in modern Berbers, while in the Levant/Europe it seems to be reduced relative to ancient samples. The 'Hadza Component' is also what differentiates Dinka from West Africans.
Unfortunately, I haven't, many times ADMIXTURE detected African related components in Natufians and Levant Neolithic, that would definitely explain haplogroup E, but then came the Lazaridis paper.
No evidence for admixture related to sub-Saharan Africans in
Natufians. We computed the statistic f4(Natufian, Other Ancient; African, Chimp) varying African to be
Mbuti, Yoruba, Ju_hoan_North, or the ancient Mota individual. Gene flow between Natufians and
African populations would be expected to bias these statistics positive. However, we find most of
them to be negative in sign and all of them to be non-significant (|Z|<3), providing no evidence that
Natufians differ from other ancient samples with respect to African populations.
The Natufians don't share more alleles with (Mbuti - Yoruba - Ju_hoan_North - Mota) than the amount the EHG or WHG shares, which is null.
this f4 test f4(Natufian, Other Ancient; African, Chimp) tests whether the population African shares alleles with the Natufians that Other Ancient and Chimp don't, if yes it would be positive, but it wasn't. see the bolded statement above.
