Are All Americans African-Americans?

The recent discovery of the oldest human remains in Ethiopia dates the origins of modern man, homo sapiens sapiens, back to Africa.

This raises some interesting questions: wouldn't all Americans be African-Americans? Would that mean that a business owned by an African-American would no longer be a "minority-owned" business? Am I now allowed to wear FUBU clothing?

Curious questions, indeed. Discuss below via the Comments link...
