Question

Before the Industrial Revolution, most peppered moths had light-colored wings that helped them blend in with the light-colored bark of trees. After the revolution, smoke from factories made the trees darker. This made it easier for predators to see light-colored moths, while dark-colored moths were harder to spot. Over time, more dark-colored moths were seen in the population.

How did genetic variation help the peppered moths survive in this changing environment?
