Hey, is human skin color related to natural selection?
Just curious 🤔 is skin color related to ancestors surviving in a different environment?

Skin color is probably one of the best examples of natural selection acting on a human trait.
Dark pigmentation offers protection against UVB and UVA near the equator. Light pigmentation, promotes seasonal, UVB-induced photosynthesis of vitamin D3 near the poles. Intermediate latitudes (seasonally high loads of UVB) favor the evolution of people with moderate constitutive pigmentation who are capable of tanning.
