Some scientific results on race and race mixing in America. The rather unsurprising results: race mixing in America is bimodal. Nonetheless it is significant present in most Americans.
My dad has tracked his ancestors back many generations. It seems that at least one of my ancestors was probably an African American ex-slave who managed to "pass" as an Indian in Maine (apparently the taboo against Indian intermarriage was less than that against "black" intermarriage). I wonder what my own racial percentages are? I think it would be a good thing for America if we found out just how mixed we really are.
