Expert
One of the classic illustrations of natural selection is regarding the moths of the industrial zones of England in end of 19th century and the starting of 20th century. As the industrial revolution advanced the bark of trees which moths landed on became darker because of the soot released from the factories. The population of light moths then reduced and was substituted by the population of dark moths as the mimicry of dark moths in new environment preserved them from predators, that is, they had an adaptive benefit in that new environment. Light moths in their turn suffered the negative result of natural selection for becoming more visible to predators and were almost eliminated. In the open forest far from factories however it was experimentally verified that light moths managed their adaptive benefit and the dark moths continued to be more simply found by predators.
