The correct answer is: The Industrial Revolution caused the proportions of each color morph in the population to become unequal.
In order to explain why the Industrial Revolution impacted the population of peppered moths in Britain, we need to understand the concept of industrial melanism.
Prior to the Industrial Revolution, the predominant color morph (or variation) of peppered moths in Britain was light-colored, which allowed them to blend in with the lichen-covered trees they rested on during the day. However, with the advent of industrialization and the burning of coal for energy, the bark of trees became covered in soot and pollution, making them darker in color.
This change in the environment resulted in an advantage for the dark-colored moths, as they could now blend in with the newly darkened trees, making them less visible to predators. At the same time, the light-colored moths stood out against the soot-covered trees, making them more vulnerable to predation.
As a result, dark-colored moths became more common during the Industrial Revolution, as they had a higher survival rate and were more likely to reproduce. This led to a shift in the population of peppered moths, with the proportions of each color morph becoming unequal.
Therefore, the correct answer is "The Industrial Revolution caused the proportions of each color morph in the population to become unequal."
