There WAS an African-American couple there too in Kenya, perhaps looking for THEIR "roots," and they were SHELL-SHOCKED at how LIGHT they were compared to the Kenyan tribes. They were dark compared to ME but almost white compared to the Kenyan tribes...ALL of them. It was good for all of us to see that.
So this article on biracial family only amuses. MOST "African-Americans" ARE biracial, whether they think so or not.
If they don't believe that statement they need ONLY to take a trip "back to Africa"--hah, what a joke--and just see with their own eyes how African they are NOT.
The sun is stronger in Africa. This makes Africans blacker (more tanned in a way)than blacks who live in America. Also as you mention, the white and Indian blood that American blacks have flowing in their veins
When WASP (White Anglo Saxon Protestant) was the term of derision for the dominant American culture Walter Williams used to call American Negros BASPs because they shared the dominant culture and had nothing in common with Africa beyond some of their genes.
There were genetic studies of African Americans finding that the average one is one third to one fourth Caucasian.
