In peppered moth population, light and dark moths are selected in different environments

due to natural selection. In areas with light-colored trees, light moths are better camouflaged and have a higher chance of survival as they are less likely to be preyed upon by predators. In contrast, in areas with dark-colored trees, dark moths are more camouflaged and have a higher chance of survival.

This phenomenon is known as industrial melanism, where the prevalence of darker moths increased during the industrial revolution due to pollution darkening the environment. However, as pollution levels have decreased in recent years, the population of light-colored moths has started to increase again.

Overall, the selection of light and dark moths in different environments is a clear example of natural selection at work, with individuals with traits that are better suited to their environment having a higher chance of survival and reproduction.
