The correct response is:
The Industrial Revolution caused the proportions of each color morph in the population to become unequal.
Specifically, the dark-colored moths became more common due to the pollution during the Industrial Revolution, which darkened the trees in their habitats. This made the lighter-colored moths more visible to predators, while the dark-colored moths had a better chance of survival and reproduction.
