What was the main reason for the increase in frequency of dark-colored moths during the industrial revolution?

Decreased pollution causing light-colored moths to die off.

Light-colored moths adapting to become dark-colored.

Genetic mutation changing light-colored moths to dark-colored moths.

What caused the increase in frequency of dark moths in the population?

Decrease in the number of light-colored moths.

A sudden mutation making all moths dark.

Alteration in the gene pool of the moth population. (correct)

Accelerated evolution changing light moths to dark.
