Arabs. THis is a historical fact that goes back at least 3000 years. Since I was a kid, I did have several Ethiopian friends and while many were "pure" black, others clearly showed that they had mixed with Arabs. One such individual explained to me that Arabs and Africans had exchanged genes for thousands of years through trade along the Red Sea. It i snot difficult even for the average untrained eye to see the similarities in facial features between some east Africans and Middle Eastern Semitic populations
This is actually wrong. There is a long history of mixing with the amhara,but not the rest of ethiopia.somalis have lived for years away from arabs,so you can't say their phenotype comes from admixture with arabs. When egyptains went to the land of punt,which they caleld the land of the ancestors they deplicted the people the same as them,soi you can;t say this phenotype comes from arab admixture. THe afars for instance in ethiopia are very isolated people,and look just like the afars. The problem with the whole hamitic racialclassification system is that it depends on a mythical white race migrating into africa and establishing civlization,which did not happen. The afro asiatic language branced out formethiopia over 15,000 years ago,and for instance the hausa in nigeria are dark as the yoruba yet they are classified as hamities.
