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.
If you live where it’s cloudy and cold, you have to be pale so your body can produce enough vitamin D, which requires sunlight.
If you live where it’s hot and sunny, you need additional resistance to damage from the sun but you’re fine for vitamin D.
People like to think survival of the fittest means bigger, meaner, stronger or smarter. It doesn’t. It just means whatever is helpful in the environment is going to do better in the long term and the frequency of those traits will increase by process of selection until the environment changes. Teamwork, compassion and empathy are major advantages for a social species. Which we are.
It is just sad to think that a pair of traits that can be equalized with a Centrum and a tube of sunscreen have been used as an excuse for so much brutality and hate.
