How do you explain the change in coloration of the English peppered moth?

These moths started out with a whitish color to camouflage into trees. Due to pollution, these trees turned a darker color. This means these light moths can easily be seen. The darker moths have more of a chance of surviving in their environment. So, these moths were able to reproduce, adapting to the new environment. So now they are a darker, black color to blend in with the trees better.

∙ 9y agoThe peppered moth (Biston betularia) is often studied for the evolutionary changes it experienced during the Industrial Revolution. The moth was commonly light colored (Typica) to blend with native trees and lichens. Due to pollution the lichens died out and the trees became blackened with soot. The darker version (Carbonaria) of this moth survived during this time because they were better camouflaged than their lighter-colored relatives. This led to the term "industrial melanism." The reduction of pollution in modern times has led to resurgence of the light-colored moths.

What is the change that occurred in peppered moths is an example of what?
Adaptation and speciation through natural selection
What effect would cleaning up the environment have on the moths?
The peppered moth population would change to a predominantly light species and the dark-colored peppered moth would diminish eventually.
What caused the mutant dark moth to become the dominant color of the peppered moth species?
I presume you are referring to the 'peppered moth' used as an example of modern natural selection in practice. Well while the peppered moth is mainly light colored, it is noted that from time to time a dark individual is to be found purely as a result of random variation. The important thing to appreciate is that in the English midlands where pollution had made all the tree bark dark, these dark individuals survived and bread because birds could not see them against the dark bark. Thus over time the peppered moth population in the English midlands was made mainly of dark colored individuals. ----------------------------------- or Because of the industrial revolution the trees turned dark and since the light-colored moths rest there they adapted to the environment so when they had baby moths the had a mutation in their DNA and became dark.
How is the peppered moth of England an example of natural selection?
The peppered moth had white bodies and wings, peppered with black. This coloration blended well into the original British countryside, hiding them from their predator the birds. Factories of the early industrial revolution covered everything with soot. Now the white stood out against the black surroundings making them easy targets for birds. Over time the white moths were wiped out. But, a few of them were darker in color, these survived and multiplied such that the white peppered moth was replaced buy the dark ones.Black moths were selected for when the trees turned black.the moths with the high fitness were selected forThe black moths were more fit for survival, so their phenotype frequency increased.
