Question

Quizplus · Accepted Answer

Evolution is the process of genetic changes in a population over time. The development of resistance to a pesticide by a population of mosquitoes is an example of evolution, as it involves a change in the genetic makeup of the population that allows it to better adapt to its environment. The other choices involve adaptations or responses to environmental stresses, but they do not involve genetic changes or evolution.
