Vibrant human diversity is now commonplace in major cities throughout the world. Some celebrate such a mix of human diversity. Others deplore it, pre… - Daniel J. Fairbanks

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.

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.

Unfortunately, many people find it difficult to accept what current science tells us about the myth of race. It runs counter to what seem to be obvious racial distinctions, mostly in parts of the world where immigration history has juxtaposed people with discontinuous ancestral backgrounds in the same place. The racial categorizations that many of us have experienced throughout our lives have likewise inculcated a sense of racial division that is not easy to abandon. Regardless of what the science shows, the perception of race and the associated racial discrimination are unlikely to disappear soon. Furthermore, a scientific understanding of human evolutionary history challenges commonly-held religious beliefs that are based on literal interpretations of biblical history.
