The Peppered Moth Provides a Well-Known Example of Natural Selection

question 1

Multiple Choice

The peppered moth provides a well-known example of natural selection. The light-colored form of the moth was predominant in England before the Industrial Revolution. In the mid-19th century, a dark-colored form appeared. The difference is produced by a dominant allele of one gene. By about 1900, approximately 90% of the moths around industrial areas were dark colored, whereas light-colored moths were still abundant elsewhere. Apparently, birds could readily find the light moths against the soot-darkened background in industrial areas and, therefore, were eating more light moths. Recently, use of cleaner fuels has greatly reduced soot in the landscape, and the dark-colored moths have been disappearing. Should the two forms of moths be considered separate species?

• A) Yes; natural selection has affected the frequency of the two different forms.
• B) Yes; they have completely different coloration.
• C) Yes; they are reproductively isolated based on habitat.
• D) No; they still can interbreed.
