Answer:

OH LOL I DID THIS IN 7TH GRADE

Explanation:

so if i remember when the trees where white the pepper moths that where white survived more often that the black ones, then when the industrial war came the trees where covered in ash, so the white moths survived

It shows how a change in an environment can effect a species natural selection, for example the white moths survived more than the black moths so the reproduced while the black moths where eaten by predator's, then when the environment changed and favored the black moths they survived and reproduced while the white moth got picked off by predators.
