As we all know, there are thousands of ethnic groups in Africa & about four distinct races. These being:
• Arabic (north Africa)
• Black African (including the Khoi & San)
• Cushitic i. e. Somalia, some Ethiopian groups, Eritrean & (north) Sudan
• European (mainly western South Africa)
The large majority of Africa is still black with black people who have genetically adapted to their different environments mainly Nilotes , west Africans/Bantu, pygmies & Khoi/San.
The main surprise some might come across is that Cushitic people are not black. I think this comes from using Usonian concepts of race when here in Africa, we can see that Cushitic people aren't 100% black. To me, they are an Arab & black (probably Nubian) mix. Some Cushitic people even say themselves that they're not black. The coloured people in the western part of South Africa are not black either & perhaps, have become their own distinct race like the Cushitic people. This is not to say that all mixed race people in Africa are Cushitic or become their own distinct race because even the Cushitic people likely still borrow Arabic & some "black" customs with the exception of the Ethiopian Orthodox Church & Ge'ez script which are independent institutions. But Cushites are probably the first independent identity created from the mixing of races in Africa & maybe the world.
