Where did Yemenis acquire their excess Sub-Saharan African admixture?

[Sikeliot]

Compared to other Arabians, Yemenis have an excess of Sub-Saharan African admixture, on par with the amount in Egypt or Morocco. And it shows phenotypically.

But from where did it come, and when?

[Kamal900]

From today's Kenya since their SSA admixture is west-African/Bantu like admixture which makes them more divergent than other Arabs who's SSA admixture is mostly east-African.

Does it specifically match Kenya or are you assuming based on something? Just wondering. I have not seen what type of admixture it was.

It's mostly from Kenya and few other countries like Tanzania.

Actually that makes sense because Swahili is there and that is a Bantu language with significant Arabic influence.
