Industrial melanism is an example of Darwin' theory of natural selection. Before industrial revolution in England the environment was unpolluted. The lichens on the barks of trees were pale. The white-winged moths could easily camouflage, while the dark winged were spotted out by the birds for food. Hence, they could not survive. After industrial revolution the lichens became dark disappeared ( due to pollution and soot **). This favoured the dark-winged moths while the white-winged were picked by birds. The population of the former which was naturally selected increased. This show that in a mixed population those which can adapt in a better way with the changing environment survive and increase in population, Thus industrial melanism in this way supports Darwin'* theory of natural selection.
