**Humans that produced more melanin became more common as populations migrated toward the equator.**

As populations migrated toward the equator, where there is more intense sunlight, individuals with more melanin were better able to protect themselves from harmful UV radiation. This natural selection led to an increase in the prevalence of individuals with higher levels of melanin in these populations over time.
