</span>In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. Peppered moth color variation is a good example of natural selection.<span>During the Industrial revolution, due to pollution, trees become darker in the urban area. Light-colored moths were, thus, easy prey. The dark-colored moths were able to camouflage on dark trees and avoid predators. The phenomenon is known as industrial melanism. So, in polluted urban areas, the number of dark-colored peppered moths increased. In the clean environment, were much effective in hiding from predators and they outnumbered the dark-colored moths.
Therefore, the </span>proportion of offspring <span>that have favorable characteristics in such environment will increase.</span>
