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.
Hi guys! I wanted to inform you about this great thing that is happening!
These smart fellows have devised a way to create cups, straws, mixers, etc that can detect common date rape drugs. This is an amazing idea and it needs funding! The campaign ends in 35 hours and they are a little short on funding. Please, signal boost this or even give a dollar if you can, it’s a great cause and something that will really change the world!
