Document Summary

First recorded change in allelic frequency based on advantages. Original museum collections had all white peppered moths and by. Fitness (ability to pass on your alleles) decreased when the moths that were more visible against the background of the trees. Fitness remains the same and is not affected by the. The bark colour of the trees have changed. The bark colour of the trees has not changed. Released dark morphs were placed on trees and observation of survival (fitness) was done, with varying tree colour environment. Artificial blacklight was used to collect released moths. Dark trees showed the same distribution as coal based industry. Do moths rest on backgrounds that match their colouration. What impact would the clean air act, that reduced pollutant emissions have on the moth population morphs. What happens to other moths with light and dark colour moths. Coming to the end of the scientific revolution. Made inventories for everything he saw, wrote books.
