To understand who we are as a species, and why we vary as we do, we must examine our genetic diversity in the context of a common African origin, fol… - Daniel J. Fairbanks

A significant minority of people fully reject human evolution, opting instead for the belief that humans were specially created with no prior evolutionary ancestry less than ten thousand years ago. Such beliefs are often infused with a non-scientific perception of different races and how the supposedly originated. And, in spite of overwhelming scientific evidence and changing social norms, a relatively large proportion of people still cling to past traditions of white supremacy and racism.

Vibrant human diversity is now commonplace in major cities throughout the world. Some celebrate such a mix of human diversity. Others deplore it, preferring that so-called races be separated both geographically and reproductively. Even today, some people retain the once-popular belief that the 'white' race is superior in intellect, health, and other attributes. Although far more people reject the notion of white supremacy today than in the past, its legacy remains, as evidenced by economic stratification, ongoing segregation, and classification by racial categories. Even among those who reject the supposed superiority of a particular ethnicity over any other, the perception of distinct, genetically determined human races often persists.

There are those who still believe that notions of racial purity are biologically and theologically sound, and therefore desirable, in spite of the fact that current genetic evidence has obliterated all justification for such notions.
