Respond to this hypothetical example of evolution: A population of peppered moths contains individuals ranging from ones that are mostly black to ones that are mostly white. The moths that are easily seen on the barks of trees get eaten by birds. If soot from coal-burning factories makes tree trunks darker in color, then there will be __________.

Question

Quizplus · Accepted Answer

The soot from coal-burning factories makes tree trunks darker in color, which makes it harder for birds to see the dark-colored peppered moths on the tree bark, giving them an advantage. As a result, the frequency of the dark-colored peppered moths in the population will increase over time, while the frequency of the light-colored peppered moths will decrease. This is an example of natural selection driving evolution in the population.
