Question

Quizplus · Accepted Answer

The genetic changes in the population of insects over many generations due to the constant use of pesticides by Richard is an example of evolution. Evolution refers to a change in the genetic composition of a population over time. In this case, the insects that were resistant to the pesticide survived and passed on their resistant genes to their offspring, resulting in an increase in the frequency of resistant genes in the population.
