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

question 5

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-nineteenth 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,because natural selection has affected the frequency of the two different forms.
• B)Yes,because they have completely different coloration.
• C)No,because there is no evidence that they are reproductively isolated.
• D)Both A and B are correct.
