Are there black people in the future?

[Calmodulin]

If we examine things from an evolutionary perspective, we need to know for how long people have been away from the Sun. The 815 years in Sirius is nowhere near enough to significantly lower melanin levels in humans genetically, albeit white people (that have a more variable expression of the protein) would probably be a lot paler. And since I'm guessing it can't be more than 2000 years humans have been flying around in ships in FL, it's a tiny-tiny time frame for evolution to work.

Also, it's interesting to ask WHY black people would lose their melanin through the generations, given due time:
Not because it's not needed, but because it's actually blocking the intake of Vitamin D (the one associated with the Sun), to the point where even here in Earth black people living in Scandinavian countries do take Vit. D supplements (don't take my word for this, I've heard it through third parties).

And the answer to our previous question leads to an even more critical conclusion:
If the black people in space get medical assistance in the form of Vit. D pills, then the genes that cause their increased melanin production and color wouldn't actually be disadvantageous to their survival.

If anything, their genes would probably just mutate and stop working after a while, since they are useless, but that's going to be a looooong while.

People in Sirius are actually going to become albinos in half a million years, if they actually don't take much Sun in, and don't get treated medically for their lack of Vitamin D. But that's a long shot.
