The skin pigment melanin is expressed differently according to exposure to sunlight, with a greater production of the molecule with greater exposure. however, the degree of production can never exceed the inherited genetic level. what evolutionary advantage would be gained from having this phenotypic range for skin pigmentation?

by having a high genetic level of melanin in your skin, you're skin is more protected from the ultra violet sun rays. Darker skinned races have more melanin present, these races originate from hot countries where sunlight is often present; the production of melanin in their skin allows them to reflect and inhibits they're skin from becoming extremely damaged. Light skinned races don't have a large amount of melanin due to they're native countries lacking sunlight. This is an evolutionary adaptation of the human race.

the evolutionary advantage would be if the species became nearly extinct because their skin color was very limited so it became noticeable. Over years it could adapt to the new environment to try and blend in with their surroundings so they could survive. Basically survival rate would go up
