C ) Humans dat produced more melanin became more common as populations migrated away from da equator

D ) Humans dat produced less melanin became more common as populations migrated away from da equator

Answer 1

The correct answer is:

**A)** Humans that produced more melanin became more common as populations migrated towards the equator.

This is because populations that moved closer to the equator were exposed to higher levels of ultraviolet (UV) radiation. Increased melanin provides greater protection against the harmful effects of UV radiation, which helps to prevent skin damage and reduces the risk of skin cancer. Therefore, higher levels of melanin became advantageous in these environments.
