So-called racial differences in IQ scores are more a consequence of disparities in socioeconomic status and the quality of education than of any gene… - Daniel J. Fairbanks

A better understanding of what science tells us about human genetic diversity is of immense importance, particualrly because it dispels false notions of what race is.

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, followed by intra- and intercontinental diasporas that transpired over a period of tens of thousands of years, culminating in an era of major migrations that reshuffled the worldwide human genetic construction over the past several thousand years and is still underway. Last, we must recognize that today’s human population is far larger, more diverse, and more complex than it ever has been. We are all related, more than seven billion of us, recent cousins to one another, and, ultimately, everyone is African.

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.
