ifreakinglovemarshmallows: thelonelyscarecrow: castiels-time-traveler: nintendocanada: mapsontheweb: 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. Yup which is why a majority of biologists find it terribly unfortunate to see so much hate in this world based on something completely natural and beautiful. It actually shocks me that a majority of people in this world don’t know this already. I’m glad this is circulating though. It’s important for people to know. -- source link
