"Skin deep" The days of classing people by skin color are over. Light skin is a mutant of dark &
continued to evolve for reasons of vitamin D from the sun & folic acid needs for reproduction. (to prevent major birth defects) We only walked out of Africa 125,000 years ago. Lets make the next 125,000 even better 
The days of classing people by skin color are over, other than ID and to correct man made social discrimination issues.
Skin Deep
Where does skin color come from? Anthropologist Nina Jablonski has worked to answer this question, and her discoveries are changing the way we understand the world's sepia rainbow of skin tones.

It also has only added details in the last 10 years. And pretty much none of it was by anthropologists. Even the Vitamin D part of the tale is from before I was born, and that was in the '50s. When I was in my 20s it was deemed offensive by no-information consumers: Imagine, skin color has a lot to do with where your ancestors have been living for the last 5000 years and blacks are black because in high-insolation areas it avoids a dip in their fertility, while in climates with less solar radiation being pale makes you more fertile, unless you consume a lot of vitamin D from other sources.
Same with hair. Hairy back? That's how we started, and you can also track how humans lost their fur. Or stomach bacterial make-up.
Next you'll start saying that nose shape, teeth shape, epicanthic folds, and a wide variety of other traits aren't who we are but side-effects, irrelevancies, of where we've been. We might even get to the point of saying that skin color and culture are only accidentally related so that "black culture" or 'white culture" is as useful as saying "sunblock culture" or "Pepsi culture" in relegating us not to who we are but defining us by something incidental and fairly meaningless. Unless the bearers of those "cultures" decide to make it so.
This is a story that's oft been told, contra Nat Geo (which may have in mind that "It's a story that's never been told on this web site"
. Remember: Nat Geo is still, at its core, primarily entertainment. If it's not breathlessly presenting something that's been known for a long time it's probably not going to survive as a corporation.
lighter skin, was because they got plenty of vitamin D and folic acid from their diet.
Fish oil, it really is good for us humans
