Slavery has introduced a strong evolutionary pressure which has a measurable effect on the genetic mix present in African Americans. Sadly, the subject is barely researched (the last time I checked, the only paper tackling the subject directly had been written by a team of Chinese researchers that are now studying the genetics of Uyghurs...), for understandable reasons (no one wants to risk having their research misrepresented by racists in search of scientific justifications).
