I agree with the overlap between us and West Africans, as the majority of Aframs could pass somewhere in West Africa. But as a whole, theres more of an obvious difference between us and West Africans when you add these people to the mix. Add that to the fact that two dark skinned relatively unmixed looking Aframs could have children that look like this. That's what makes the difference between us and our West African ancestors more obvious than with White Americans and Europeans.
