Washington Post writer David Brown reviews a recent study that analyzes genetic information from 53 human groups, comparing and contrasting what makes us human.
Generally speaking, all people groups seem to fall into “just three” categories, Brown reports.
Generally speaking, all people groups seem to fall into “just three” categories, Brown reports. According to evolutionists, this tripartite division originated when humans left Africa tens of thousands of years ago, splitting into African, Eurasian, and East Asian groups (the third of which includes Pacific Islander and Native American groups).
For creationists, that division makes plain sense as reflective of the people groups that split off after Babel, all descendants of Shem, Ham, and Japheth. Of course, in the millennia since, those people groups have migrated and interbred, so it’s difficult to say perfectly what modern groups belong to what ancestor—or even to imply that the ordinary human descends from just one of Noah’s three sons/daughters-in-law. Additionally, the genomes have been influenced over the years by environment. So a population of Shem’s descendants and a population of Japheth’s descendants living in the same environment for millennia would come to resemble one another. Brown makes the point, albeit from an evolutionary perspective:
People adapted to what they encountered the way all living organisms do: through natural selection. A small fraction of the mutations constantly creeping into our genes happened by chance to prove beneficial in the new circumstances outside the African homeland. Those included differences in climate, altitude, latitude, food availability, parasites, infectious diseases, and lots of other things.
Nonetheless, the study is an exciting reminder of the reality of the Genesis account.
But what else is interesting is that the three broad groupings in the study aren’t as different as evolutionists expected. Brown writes, “Scientists have long known that regardless of ancestral home or ethnic group, everyone’s genes are pretty much alike. We’re all Homo sapiens. Everything else is pretty much details.” Brown identifies skin color as the “most obvious” of these details. Of course, that reflects what creationists have emphasized, but differs from what some evolutionists originally preached (see Darwin’s Plantation for more). He goes on, “Population geneticists expected to find dramatic differences . . . [but] that’s not what scientists have found. Dramatic genome variation among populations turns out to be extremely rare.”
The entire study reminds us of how the variation we see among human populations today could have arisen as our forbears left Babel. Genetic drift and natural selection played important roles over time, which is why any two humans randomly selected may differ in stature, skin color, disease susceptibility, lactose tolerance, and so forth—even while all of us remain entirely and equally human. The Bible’s message in Acts 17:26—that we are all of one blood, descendants of Adam through Noah—is a powerful truth explaining our world.
