Thing is ''African Americans'' and Caribbeans are from the same continent; North America. You manage to distinguish the two yet find a hard time distinguishing the various, more diverse and more distantly related groups of Africa.<quoted text>
where you have a large number of afr-descendant groups, aa, afro-latino, caribbean, as we do on the east coast, you see high frequencies of cross-ethnic mixing.
there are more africans showing up in the soup, but they for the most part are an outside isolated group. when africans marry non-africans it's usually white.
eg; A Jamaican and an ''African American'' are much, much, much more closely related than say a Nigerian and an Egyptian who would make an ''IR relationship'' even.
So the fact that you went on to say ''when africans marry non-africans it's usually white'' is beyond me. When a west African marries a north African more time that will be ''interracial'' completely different cultures etc.
What you state probably only applies to the USA or your region of it as ''Africans'' are not an isolated group here in regards to the black population especially.
Like I said before perhaps the US gains a different class of Africans or something because a significant amount here quickly assimilate to western ways and drop tribalism; within a generation. The same for what I noticed in France and what ''attai1'' stated.
