Wasn't that haplogroup in the sudanese just acquired through admixture with arabs though ?
I don't know where they're originally from, but how do you suppose the hausa ended up speaking an afro-asiatic language ? unless you think the language is native to west africa ?
In regards to the haplogroup historians and geneticist have to do more research, because i find it very weird that Egyptians rarely carry that variant J1, and they (Egyptians) were arabized or islamicized way before Northern Sudan/Parts of Upper Egypt. I am not saying admixture did not happen, however it is not to the degree that the inhabitants got replaced like in the United States or Carribbean or Argentina.

That is a good question. However the thing is we should not racialize a language group. For example some of the Omotic tribes in Ethiopia also speak a Afro-Asiatic language.
