It’s my understanding that all of humanity shares common ancestors that left Africa 40k-60k years ago and populated this entire globe (the jump-off dates are a matter of ongoing investigation and discovery, but our genetic commonality is not.) Genetic research has proved this almost without a doubt. A good source, though somewhat dated today is a documentary called The Journey of Man produced by PBS. Continuing genetic investigation since that was produced indicate that there has been some small contribution to our genome by Neanderthals and another hominid, now extinct, that lived in southeast Asia.
We are all one species and what we call race today is merely the superficial adaptations to different environments through the accumulation of thousands of years. It is rather ironic that all of us came from that small same stock and now we don’t recognize each other. Genetic research also shows that there is more genetic variance within each “race” than there is between the “races.”
So what we’re really talking about when we talk about race is tribalism, clan-ism, group identities of bands of hunter-gatherers developing in isolation each from the other in a former world sparsely populated by humans.
But I am an equal opportunity gad-fly and I would not wish to merely throw these facts in the face of white supremacists, but to go even further and tell all religionists of every stripe that deny evolution that it is very likely that those bands of wanderers that left Africa so long ago evolved from pond scum, along with all the other life on this planet.
