“Let's look at one more quick example of modern evolution atwork. In the early 1800s, light-colored lichens covered many ofthe trees in the English countryside. The peppered moth was alight-colored insect that blended in unnoticeably with the lichens.Predators had great difficulty distinguishing the peppered mothfrom its background environment, so the moths easily survivedand reproduced. Then the Industrial Revolution came to the English country-side. Coal-burning factories turned the lichens a sooty black. Thelight-colored peppered moth became clearly visible. Most of themwere eaten. But because of genetic variation and mutation, a fewpeppered moths displayed a slightly darker color. These darkermoths were better able to blend in with the sooty lichens, and solived to produce other darker-colored moths. In little over a hun-dred years, successive generations of peppered moths evolvedfrom almost completely white to completely black. Natural selec-tion, rather than "random accident," guided the moth's evolution-ary progress.”
