[AI-generated answer — Bot GPT 3.5]

Humans that produced more melanin became more common as populations migrated toward the equator. This is due to the evolutionary advantage of having darker skin in regions with higher levels of ultraviolet radiation from the sun, which helps protect against sunburn and skin cancer. On the other hand, humans that produced less melanin became more common as populations migrated away from the equator, where there is less intense sunlight and a greater need for the production of vitamin D.
