Document Summary

Industrial revolution leads to the decrease in fitness value for the light peppered. Natural selection is a primary role in evolution. Natural selection leads to the sustaining of favorable adaptions through a process involving the uneven survival of organisms due to environmental forces. Biston betularia, also known as the peppered moth, is a species of moth living in england. There are types of peppered moths, the light colored and the dark colored moth. Prior to the 1800"s there was a vast abundance of light colored moth. Though, due to the industrial revolution soot caused all the tree trunks to turn black. After this occurred the dark moth suddenly became extremely abundant while the light moth became a rarity. This is believed to be due to the fact that since the trees were now black, the dark moths could blend in and were eaten less by birds (evolution and natural selection).

There is a moth in England called the peppered moth. BeforeBritainâs industrial revolution, these moths were usually âsalt andpepperâ colored. Because of their coloring, they blended in wellwith the tree trunks on which they tend to rest. The coloringhelped them hide from the birds that ate them. During the Britishindustrial revolution, industry expelled a lot of soot from theburning of coal into the environment. This soot darkened the treetrunks and it was noted that black colored moths were becomingpredominant. The idea is that with soot in the environment, blackcolored moths fair better than light colored moths. There is somedebate as to whether this is actually the case or not, but for thesake of this question, letâs assume it is.
