Zoology - Evolution Question with Solution | TestHub

One of the most striking examples, which demonstrates the action of natural selection, is the industrial melanism in England. The peppered mothBiston betularia, with a dull grey colour, was abundant in England before the industrial revolution. A black coloured form of the same moth (melanic, a dominant mutant differing in a single gene),Biston carbonaria, was very rare. After industrial revolution, the proportion ofBiston carbonaria, increased to almost 90 percent.
