Why did the population of peppered moths in England change from light to dark after the Industrial Revolution?

• Light moths were easy to see against sooty trees and were eaten
• Light moths were killed by soot
• The birds that ate the dark moths were killed by soot
• Dark moths were produced by industrial processes

The example of the peppered (brown) moths living near English industrial cities demonstrates that

• A change in an environment can result in the evolution of species living there
• Evolution occurs so slowly that is it not possible to determine that it has happened in less than a million years
• The environment near these cities has always favored dark colored moths

• Because the trait is an acquired phenotype.
