With Europe getting warmer due to climate change, how long do you think it would take to reativate the recessive genes that make for higher melanin production? (lemmygrad.ml)

Kind of a shitpost fyi, but since all humans initially had dark skin (more melanin) and only slowly got fairer skin (less melanin) in regions with less UV radiation in the northern hemisphere, would this also be reversable?

How long does it usually take to see these changes in mammals? Probably thousands of years right?

I mean it would kind of solve racism if we don't have a political system by then that treats all humans like humans.

Please don't take this post too seriously I just had this idea of a white supremacist having an identity crisis due to having more darker skinned children because of climate change haha (Insert some joke about Yakubian apes here)

White people developed low melanin as a way to combat low amounts of UVa radiation. The change in climate is unlikely to make the ability to absorb UVb radiation a liability.

From what I understand of the green house effect is that higher temperatures lead to more cloud cover and thus less direct UV. If that's correct its quite possible that Africa will become lighter skinned as the need to absorb UV through clouds increases.

Is this Yukkub's last dastardly plan coming to fruition?
