The skin color diversity in primates over the last 20 million years showcases the adaptability of primates. The melanin levels in primate skin vary significantly based on the varying levels of UV radiation exposure in different climates. In high UV regions, darker skin evolved to protect against UV damage and folate degradation, while in areas with less sunlight, lighter skin developed to facilitate vitamin D synthesis through the skin. This adaptive trait is not static; it can change over millennia as populations move between different UV environments.

Skin Color Diversity Across and within Primate Species
By 14 Million Years Ago
Phenotype Variations
And now, a premium bonus.
Skin color diversity is far older than humanity. Across many animals, pigmentation varied by species, population, body region, environment, and evolutionary history.
Subject: Ancient adaptive patterns.
Race is a human story placed on top of ancient biology. Skin color came first as adaptation and variation, not as hierarchy. Long before humans invented categories of “us” and “them,” primate bodies were already expressing the simple truth of evolution: life changes as environments change.
Flashcard.
A pigment that helps shape skin, hair, and eye color and protects tissue from ultraviolet radiation..
Answer. Melanin.
