Correct. Blacks have very distant relation to us. They never left sub saharan Africa except as slaves. There were multiple migrations into and back out of Africa (which is the basis for completely debunked out of Africa theory). Little mixing occurred. Whereas most of the others had various mixings, blacks largely bred with something entirely missing from the fossil record, which was much closer to ape than modern hominids. Basically blacks are the hybrid of two most old and primitive hominids. A fact which is very obvious from appearance. Which becomes a bit conflated as American and European blacks and have heavily interbred with Europeans, significantly effecting their appearance and masking much of their primitive, regressive genetics. Which is, of course, why Aryan women are constantly encouraged to end their genetic line with blacks and other non-whites.
