How does the peppered moth show evolution?
The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. Later, when pollution was reduced, the light-coloured form again predominated.
What color were the trees around Manchester before 1845 what color did they change to what caused the change?
light grayish color

What happened to the peppered moths?

As the trees darkened with soot, the light-colored moths were easier to see. They lived longer and passed their dark colored genes onto their offspring or young.
How does the example of the peppered moths fulfill the 3 rules of natural selection?
Because predators were able to spot the light moths more easily, the dark moths were more likely to survive and reproduce. The peppered moth case is an example of natural selection. In this case, changes in the environment caused changes in the characteristics that were most beneficial for survival.
What are the two types of peppered moths?
This species has two different adult forms. One form of the species, typica, is a pale lighter color that is peppered with black speckles. The other form, carbonaria, is a much darker color that is peppered with light speckles.

What color is the typical version of the peppered moths?
