How have the historic levels of melanin in human populations changed due to migration? (1 point)

• Humans that produced less melanin became more common as populations migrated away from the equator.

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

• Humans that produced more melanin became more common as populations migrated away from the equator.

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

The correct statement is:

• Humans that produced less melanin became more common as populations migrated away from the equator.

This is due to the fact that as populations move away from regions with high UV radiation, such as near the equator, there is less selective pressure for high melanin levels, which provide protection against UV damage. As a result, lighter skin became more prevalent in populations that migrated to higher latitudes.
