Question

explain what happened to the peppered moths in the industrial revolution.

Explanation:

Before the Industrial Revolution, most peppered moths had light - colored (peppered - like) wings. This coloration helped them camouflage on light - colored tree barks, protecting them from predators. During the Industrial Revolution, factories released a large amount of soot, which darkened the tree barks. Light - colored moths became more visible to predators (like birds) and their survival rate decreased. Meanwhile, dark - colored (melanic) peppered moths, which were previously rare, had a survival advantage as they could camouflage on the now - darkened tree barks. So, the population of dark - colored moths increased, and that of light - colored moths decreased. This is a classic example of natural selection, where the environment (pollution - darkened trees) favored the survival and reproduction of the better - camouflaged (dark - colored) moths.

Answer:

Before the Industrial Revolution, light - colored peppered moths were common (camouflaged on light tree barks). Industrial soot darkened tree barks. Light - colored moths were more visible to predators and their numbers dropped. Dark - colored (melanic) moths, now camouflaged, survived better, so their population rose. This is natural selection driven by environmental change.
