Before industrialization $:-$ Natural selection of dark moths

Vedclass · Answer

(A) The case of $Biston$ $betularia$ (peppered moth) is a classic example of natural selection. Before industrialization,the tree trunks were covered with white-colored lichens. White-winged moths were better camouflaged against the white lichens and thus survived,while dark-colored moths were easily preyed upon by birds. Therefore,before industrialization,there was a natural selection of white-winged moths. After industrialization,the soot and smoke from factories killed the lichens and darkened the tree trunks. This made the dark-winged moths better camouflaged,leading to their selection. Option $A$ is incorrect because,before industrialization,the white-winged moths were favored,not the dark ones.
