Industrial melanism (In England) is an example of natural selection. Natural selection is the process by which the organisms that are best suited for their environment survive and reproduce. Before industrialization (1850s), it was observed that there were more white winged moths ( ) on trees than dark winged or melanised moths (). Because there were more white coloured lichens that covered the trees. Hence, white winged moths were able to camouflage themselves and survived. But the dark coloured moths were picked out by predators. After industrialization (1920), there were more dark winged moths and less white winged moths. Because, the tree trunks became dark due to industrial smoke and soot. Under this condition the white winged moth did not survive as the predators could identify them easily. However, dark winged moth survived because of suitable dark background.
