Map of the World by Natural Skin Color
i’m really dumbfounded that i never realized skin colour is literally just caused by being closer to or farther from the equator and the resulting sun exposure and skin darkening
actually, its an adaptation. natural selection. people with darker skin are selected for in areas near the equator, where the melanin that causes the darker color protects them from radiation and protects them from skin cancer and other health defects, and because they are healthier they can pass on that trait more. people near the poles have lighter skin because it allows them absorb more of the limited sunlight to convert to vitamin d.
THIS IS THE THING SOME PEOPLE HATE OTHER PEOPLE OVER.
Evolution of melanin levels based on geographical location.
Where are the Inuit? You know, brown skinned aboriginal peoples located in the northern part of Canada and some of Europe? Cause they sure as hell aren’t white..
Probably in the swath that’s labeled “no data.” I’d like to see stats for those regions myself.
it has to do with diet.
lighter skin is selected for in areas with little sunlight because dark pigmentation is not needed (or is needed to a lesser extent) to protect one from UV radiation (and thus its production becomes an unnecessary energy expenditure) AND because sunlight is important in the production of biologically available Vitamin D (less sun = less opportunity to produce Vitamin D = more sunlight needs to be allowed “in” = lighter skin).
however, a traditional Inuit diet consists mainly of fish, walrus, seal, and other seafood which is naturally high in Vitamin D. this dietary Vitamin D occurrence compensates for their darker skin.
also, since the environment is white (covered in snow, and thus highly reflective) for much of the year, darker skin helps to protect from the UV radiation reflected off the surface of snow.
