Why Did Our Skin Color Evolve to Black and White?

The evolution of skin color into dark and light; as a result of environmental, genetic and adaptation factors appeared.

Especially exposed to during the evolution process UV rays and vitamin D play a serious role. Let’s explain how.

Sunlight has an effect.

UV rays, in particular, play a big role in our skin color evolution. Ultraviolet, Promotes vitamin D production (It is worth remembering that overexposure also has harmful consequences.).

“So what does vitamin D have to do with skin color?” If you say; Dark skin color evolved because people in tropical and equatorial regions were exposed to more UV rays high melanin (Prevents skin cancer through DNA damage) and protects from ultraviolet.

When we go to high latitudes where there is less sunlight, DNA synthesis becomes difficult and light skin color develops. containing less melanin It increases vitamin D production.

So the first people in Africa were black.

Our earliest ancestors in Africa had dark/black skin tones because they were more exposed to UV rays due to the region they lived in. Of course, they did not remain fixed in a single region and towards latitudes where there is less sunlight They started to spread.

As people with this black skin color left Africa and migrated to different parts of the world, genetic diversification to adapt to different climatic conditions happened.

White/light skin was revealed.

Compared to their previous generations, especially those who spread and settled in areas with less sunlight They started to have lighter skin tones.

Additionally, skin color is different in some societies. Since he is a cultural figure, he can influence sexual selection. Thus, a certain skin color becomes more common in a population.
