Caucasoid or Caucasian is not a reference to being 'white' (Northern European) in the modern sense. I take it you're imagining I'm saying that they are Germans or whatever, which they are obviously not.

"Studies conducted on Ethiopians belonging to Semitic and Cushitic ethnic groups mostly from the north of the country (Oromo, Amhara, Tigray, and Gurage), estimate approximately 40% of their autosomal ancestry to be derived from an ancient non-African back-migration from the Near East, and about 60% to be of native African origin (from a population indigenous or "autochthonous" to the Horn of Africa)"
"In Pagani, Luca et al. (2012), this non-African component, is estimated to have entered the Horn of Africa roughly ~3,000 years ago and was found to be similar to the populations in the Levant. The paper goes on to say that this coincides with the introduction of Ethio-Semitic languages into the region.
[48] Gallego Llorente, M et al. (2015) discovered extensive admixture in Eastern Africa from a population closely related to early Neolithic farmers from the Near-East/Anatolia.
[52] López, Saioa et al. (2021) found that when comparing Ethiopians to external populations only, Nilo-Saharan speakers (as well as the Chabu, Dassanech, and Karo) in the southwest shared more recent ancestry with Bantu and Nilotic speakers, while Afro-Asiatic speakers in the northeast shared more recent ancestry with Egyptians and West Eurasians. The study revealed that groups belonging to the Cushitic, Omotic, and Semitic branches of Afro-Asiatic show high genetic similarity to each other on average.
