Natural selection

Vedclass · Answer

(A) Industrial melanism is a classic example of natural selection. In $19^{th}$ century England,before industrialization,white-winged moths were more abundant than dark-winged moths because they were camouflaged against light-colored lichens on tree trunks. After industrialization,the tree trunks became dark due to soot and smoke,which killed the lichens. This made the dark-winged moths better adapted to their environment as they were less visible to predators,leading to an increase in their population. This process,where nature selects the organisms better adapted to the environment,is known as natural selection.
