Is skin pigmentation really a form of camouflage in people?
Actually the reason that people in colder regions developed lighter pigment was because there wasn’t a lot of sun. In africa there are a lot of places with a lot of sun and the darker pigment makes their skin less susseptable to the harmful rays. Melanin (the substance that makes skin dark) is a natural sunblock. This is what is we call a tan. Sun light makes the cells that create melanin create more causing the skin to be darker as a natural response to the burning of your skin by the sun. Edit: Also the sun provides us with a couple of natural and needed nutrients. Vitamin D to help us absorb calcium, and helps us produce Karotin ( a waxy substance produced in the skin that fills the cells as they move towards the outside of the body. Your outside skin cells have no innards like a neucleus, those are all shed and replaced with karotin, gives us a water tight skin, pores are where water and other liquids are absorbed, and helps protect against bacteria and other would be invaders), Th
