Ethiopians have 35% Yemani Arab ancestry that probally comes from the Sabeans that migrated into Eastern Africa across the Red Sea. However this is only true amung the Amharan who are a mixture between Agnew Cushic people and Sabean Yemani. In the past,anthropologist used to classify Africans because of their aquline nose into the classification of caucasoid. This is what was called the Hamitic myth that still persists to this day. Nasal shape is not caused by intermixture,but from the tyope of clime that a person evovles in.
