I read a very interesting article this morning, that I do believe is correct on where we are going if all the intermingling of ethnicities continues at the rate it is going. Which I do believe it will, if not speed up. And I know this is still what scares so many who still believe in “racial purity” which doesn’t really exist anyway. Here is what University of Delaware evolutionary biologist John McDonald said in the article when talking about what to expect over time as more and more people mix:
Most of the traits that we think of as distinguishing different groups (hair color, skin color, hair curliness, facial features, eye shape) are controlled by multiple genes, so they don’t follow a simple dominant/recessive pattern,” McDonald explained. “In those cases, blending will make people look more similar over time.”
It’s not straightforward to predict how blending of genes affects physical appearances, but McDonald said the tendency is for such traits to average out. The average American skin and hair color will probably darken slightly, and there will be fewer people with very dark or very pale skin and hair.
The genetic mixing under way in the United States is also happening to a greater or lesser degree in other parts of the world, the researchers said. In some places, unique physical traits tailored to the habitat still confer an evolutionary advantage and thus might not bow out so easily; in other places, immigration happens much more slowly than it does elsewhere. According to Stearns, perfect homogenization of the human race will probably never occur, but in general, Earth is becoming more and more of a melting pot.
A population forged from the long-term mixing of Africans, Native Americans and Europeans serves as an archetype for the future of humanity, Stearns said: A few centuries from now, we’re all going to look like Brazilians.
How very interesting.
