Current anthropological and genetic evidence clearly supports the conclusion that early modern humans evolved dark skin pigmentation as a natural selection adaptation to protect against high ultraviolet radiation levels near the tropics.

The analysis

Both retrieved papers consistently support the scientific consensus that human skin pigmentation is an adaptive trait shaped by UV radiation, with dark skin evolving under high-UVR conditions for photoprotection.

Jablonski (2010) explains that dark, eumelanin-rich skin pigmentation evolved near the equator as a photoprotective adaptation driven by high ultraviolet radiation to protect folate.

The genetic architecture of human skin pigmentation: evolution and adaptation across global populations

The review by the authors (2026) reinforces that human skin pigmentation is a dynamic, highly adaptive trait whose global diversity is fundamentally driven by variation in ultraviolet radiation.
