Imagine the birds that eat peppered moths went extinct. What would happen to the peppered moth
population? What will be an ideal response?
At present, the birds provide a selective pressure on the peppered moth population. Since the trees are
currently free of pollution, the lighter colored moths are less likely to be eaten and thus are more
prevalent. In the absence of selective pressure however, both light and dark moth types would survive
equally, and it would be though the population would come to be a mix of light and dark colored
moths unless some other selective pressure against color were active.
