Answer 1

The correct response is:

The Industrial Revolution caused the proportions of each color morph in the population to become unequal.

During the Industrial Revolution, pollution darkened the surfaces of trees in many areas, making dark-colored moths (known as melanistic forms) less visible to predators compared to light-colored moths, which became more vulnerable. As a result, the dark-colored moths became more common in polluted areas, demonstrating natural selection in response to environmental changes.
