Industrial melanism. It is an example of natural selection shown by peppered moth Biston betularia. The moth had a dull grey coloured body before industrial revolution in England. The colour of moth enabled it to adapt to the light coloured background. After the industrial revolution the environment changed with the deposition of tar soot on the bark of the trees. As a result, light coloured species of moth were easily detected by the predators against the dark bark of trees while the black coloured moth Biston carbonaria increased in number. The change enabled the animal to adjust with the changed environment.
