Good point, but for us our Natufian-like/ancient Nilotic ancestry is close to half/half. With Semites they can be 80%+ Natufian. How does that happen?
Why adopt the language of the people you conquered? The R1a carriers still retained their Indo-European language whereas the j1 conquerors switched to Semitic which was spoken by the conquered Natufians.
Natufian like ancestry was never ours anyways. It was brought to Africa by Anatolian hunter gathers (not to be confused with Anatolian farmers who are much younger) . We most likely killed their men off and took their women when they entered Africa through Sinai.
R1b (V88) for example is prevelant in Africa today amongst Chadic speakers from Cameroon, Chad all the way to South Africa. These R1b V88 men came with the Anatolian farmers from the direction of Spain, Italy into the Maghreb. R1b-V88 originally was a western hunter gatherer before being an Anatolian farmer.
So R1b-V88 in Africa started off as a western hunter gatherer then adopted the Anatolian farmer genetics then adopted the Afro Asiatic language when they came Africa. It was then taken by Chadic speakers from the Sahara to what’s now Cameroon, Namibia, Congo, South Africa etc. They all speak different languages today these men
