Vedclass · Answer

(A) Industrial melanism is a classic example of natural selection. Before industrialization in England, the white-winged moths were more abundant on tree trunks covered with lichens, which provided camouflage against predators. With industrialization, soot and smoke killed the lichens and darkened the tree trunks.

Therefore, the dark form was naturally selected in polluted industrial areas.
