A significant minority of people fully reject human evolution, opting instead for the belief that humans were specially created with no prior evoluti… - Daniel J. Fairbanks

Under the guise of eugenic improvement and racial purity, and what the implementation of eugenic measures could supposedly do to improve human society, notions of racial superiority continued in popularity, but with a purported scientific foundation.

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.

Classification is real, but it is based much more on a set of social definitions than on genetic distinctions. Legally defined categories for race differ from one country to another, and they change over time depending largely on the social and political realities of a particular society or nation. The notion of discrete racial categories arose mostly as an artifact of centuries-long immigration history coupled with overriding worldviews that white superiority was inherent, a purported genetic destiny that has no basis in modern science.
