The peppered moth is a species of moth found primarily in Europe and North America. It is known for its distinctive coloration, which varies from light to dark. This variation helps the moth blend into its environment, providing camouflage against predators like birds. During the Industrial Revolution, the peppered moth population shifted dramatically. Darker moths became more common in polluted areas, as they were less visible against soot-covered trees. This phenomenon is a classic example of natural selection, where environmental changes influence which traits are favored in a species.
