The Peppered Moth is a species of moth found primarily in Europe and North America. It is known for its distinct coloration, which varies from light to dark. This variation helps the moth blend into its environment, providing camouflage from predators. During the Industrial Revolution, pollution darkened tree bark, leading to an increase in dark-colored moths, a phenomenon known as industrial melanism. As pollution decreased in the late 20th century, lighter moths became more common again, demonstrating how environmental changes can influence natural selection and adaptation.
