Horn of Africa
According to Dobon et al. (2015), the results were not conclusive and states that there needs to be more studies on the East African samples. Dobon et al. states:”Our main results add new and interesting features to the North East African genetic complexity, with new populations that define a genetic component in southern Nilo-Saharan speakers that cannot be related to a North-African or other sub-Saharan components. These populations should be included in further population genetics and epidemiological studies to have a representative sample of the genetic diversity of the region of East Africa.”The scientists involved in the study suggest that this points to a common origin for the general population of Egypt. They also associate the Coptic component with Ancient Egyptian ancestry, without the later Arabian influence that is present among other Egyptians. The Coptic component is roughly equivalent with the Ethio-Somali component.
