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)

That would be the funniest thing ever, of course I'm sure the racists would just move the goal posts.

As for time scale, I'm not sure if anyone knows the time scale of the initial development of lighter skin tones. Could have been thousands of years, could have been hundreds of thousands. It probably wasn't faster than that, because if it was then we would have enough data by now to see the effect in certain populations that have migrated latitudes within written memory.

But here's something to consider: sometimes evolution can produce effects over surprisingly short periods of time, so it is theoretically possible for this to happen as a result of climate change even if it's very unlikely, so don't lose hope.
