I have a question regarding this haplgroup. Who do you think brought this haplgroup to the horn? I think it's likely just based on the tmrca of the haplogroup to come from outside Africa. Places like Yemen would seem logical, but considering how oversampled the arabs are when it comes to Y haplogroup testing, we should see alot of saudis, qataris, yemenis etc match our subclade but they don't apart from a few arabs that come from cosmopolitan areas. So I don't think its specifically arabian.
