The biological basis for different skin colour is the amount of
melanin in one's skin cells. There is no melanin content, however,
above which one is "Black" and below which one is "White." There are
"Black" people with lighter skin than mine. There are "Black" people
with blonde hair and blue eyes.
Similarly, there is no metric for facial structure (or any other
biological feature) that can be used to accurately categorize people
