Answer:
Because less common black moths became better suited to survive the change in the environment.
Explanation:
Peppered moths after the industrial revolution showed the process of natural selection because the less common black moths became better suited to survive the change in the environment. Before the industrial revolution, the most common variety of moths was the white one with black dots and it was rare to see the carbonaria that were the black ones. With air pollution from factories, the trees that were white because they were covered with lichen turned to black. The black moths were more able to camouflage from predators, survive, and reproduce and thus became more common.
