it's probably nowhere near as important as the higher IQ in white populations.

Did the higher IQ cause the spread of white skin? I think that is far more likely.

Optimum skin color is based on the amount of sunlight and the darkness of the dark season. High latitude people need pale skin to get enough vitamin D. Unless they consume lots of marine meat that supplies vitamin D, like the darkish Inuit. Equatorial people need dark skin to protect the vitamin folate from photo-destruction, and also to reduce skin cancer. If high intelligence had evolved first closer to the equator, the color correlation would be reversed.

If you read this, it sounds like white skin is vastly superior in northern climates.

Evolution is just adaptation. Assigning superiority is a very human and egotistical trait. No finch is more superior than the others and white skin sucks in the desert.

right....exactly why the African continent leads the world with its technical marvel of accomplishments /s

Africans did not evolve in such a way, there was no need to be innovative. They live in a warm climate where food is available year round. They are also the only sect of humanity that hasn't killed off their megafauna.

Europeans and Asians did have winter to prepare for. So they had to get smart and learn more forethought and invention.

I'm not saying we're biologically equal, that's silly. I'm just saying we are what we are. It would be great if we just left the Africans to their own devices and basically adopt a prime directive.

All of this DNA based research will lead to many discoveries about who we really are and about why we are so different from the so called African wanderers. In TFA, it mentions that one huge factor is that a different people poured out of Scythia who already held these trait, yet it does not talk about them or about why they possessed such wonderful trait, and how did these invaders just happen to have traits we normally consider European. Very interesting people, but a very incomplete article.

Yin and Yang. More black, less white; more white, less black.

Survival is a balance of trade-offs. Big Brains or Fast Legs. It would be great to have a Big Brain in a Big Skull, but then female legs would need to be further apart, which would mean Slow Legs. (Narrow hips are better engineered for faster sprinting.)

If you don't need a Big Brain, because food is always abundant, there is a tendency to evolve for faster legs. If you migrate to the cold, a big brain helps you plan and find food, so it is worth sacrificing some speed for brain power.

What about the role of sexual selection?

Lighter skin is due to natural selection for vitamin D absorption from the Sun.

No, skin color does not impart superiority or inferiority.

Then blacks will eventually turn white in colder climates?

They get rickets from lack of vit D, so... If they were left completely alone in a cold climate with without any modern assistance, all of them would die, their skin would eventually lighten, or they'd develop some other means of acquiring vitamin D.

is this why Africa's space program dominates the world?

You're not doing your "race" any favors with such shallow, animalistic, cause/effect mentality. Try broadening your perspective. Or kill yourself.
