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.
On a related note, nose shape has been shown to correlate to the air conditions of the region ones ancestors adapted to. Longer narrower noses are great for giving dry, hot air a chance to cool down and gain moisture before entering the lungs. Wide flat noses are adapted to cutting down on moisture inhaled in humid climates. Shorter, tinier noses are helpful for those living in colder climates as there is less exposed skin and air can stay warmer since it has less distance to travel. Hooked noses are good at cutting down on sand, dust and other airborn irritants from flying in.
It’s kind of mind boggling that a lot of racism stems from “YOUR ANCIENT ANCESTOR WAS BETTER ADAPTED FOR SURVIVAL IN ANOTHER BIOME. How DARE YOU”.
