During the industrial revolution, peppered moths underwent a drastic change in common coloration that highlights the way natural selection works. Traits that are best suited to a particular environment typically help an organism to survive and pass those traits on to their offspring. The activity uses the relative number of pale and dark forms in different environments as a … Following the clean air act of 1964, soot deposits have dramatically declined, and black peppered moths have declined with them. A Case of Natural Selection The theory of natural selection suggests a mechanism for evolution and gives us a way to explain the variations we see in living organisms and the changes evident in the fossil record. A dark form of peppered moths, once rare, became common. Keep in mind, evolution does not select for the ‘best’ organisms – neither the light or dark moth was a better moth – they were just different variations within a species. There are four principles at work in evolution—variation, inheritance, selection and time.
