Not fully relevant but
Afaik all black people are 'recently' descended from africans. Humans evolved in africa, some later moved to europe and and asia. The people in europe and asia ended up white and the people who remained in africa ended up black. Since we only recently gained te ability to quickly travel large distances, humans tended to mate with other humans who lived close to them. For a long time, black people mostly mated with other black people etc, and very few people emigrated. Almost everyone who is black come from families who lived in africa within the last few hundred years.
The white africans in southern africa are all recent immigrants. The only non-black people whose families are historically african would be from the very north of africa.
