Why do humans varies in skin tones? Will there be 2 human that shares the exact same pigment color?
In: Other
In short the variance in pigmentation has to due with ancestral heritage and what region of the world your bloodline comes from. People in areas with higher sun exposure generally developed more pigment because the melanin in their skin is used to help protect them from the harsh sunlight. In areas where the sun isnt so strong, closer to the poles people are lighter in skin tone.
