The use of pesticides on crops has been a common farming practice for decades. What has been the greatest effect of natural selection through the use of pesticides on certain insect populations?

• Natural selection has been altered because the insects and their predators are killed.
• The rate of selection is increased because the pesticides do not kill the insects that are naturally resistant to it.
• The rate of selection has decreased because the pesticides kill only young insects.
• The pesticides have altered natural selection by causing the insect DNA to spontaneously mutate.
