Its beyond all doubt that Reer Xamar come from Persia.
You may ask where I'm getting this idea - just look at the contributions they've made to Somali culture. Niiko, Xalwo, tobacco - a bunch of innovations that are totally foreign to Yemenis. Reer Xamar softened the harsh Somali lifestyle, and Yemenis are not soft people. The queer culture of Somali Benadiris is completely out of touch with Yemen's hard tribal worldview, period.
After centuries of inter-marrying, Benadiris still maintain a certain look. Yemenis just look like white Somalis, if a Somali mixes with a Yemeni you'll have something that looks similar to a Somali, case in point Hyperactive. But strong Persian genes are harder to erase and thus you still have a strong appearance in that community.
There is an understanding that the Benadiris are the descendants of merchants. We all know Yemenis are inferior merchants and seafarers.
Names are a clue too - Mogadishu comes from the Persian "Maqq ad di Shah" which means "Seat of the Shah." Also look at the names of Reer Xamar like Geylani, which is a well known Persian name. There is also an Italian Geylani but its absurd to think they took Italian names.
A well known Yemeni community in the Horn of Africa are the Rashaida of Eritrea and Sudan - they have strong tribal communities and a distinct nomadic heritage. Its clear that Somali Benadiris are urban, educated people, which definitely means they are not Yemeni.
My research is complete.
