- What is the difference between evolution, natural selection, and artificial selection? A. Evolution is a genetic change in a population over time which can occur through natural selection. Artificial selection is the differential reproduction of individuals in a population to promote the characteristics chosen by the breeder. B. Natural selection is the change of allele frequencies in a population over time. Evolution leads to differential survival and reproduction of individuals. Artificial selection has produced domesticated animals and plants. C. Evolution is a mechanism of artificial selection. Natural selection is a form of artificial selection in which nature selects the characteristics that are most beneficial to a species. D. Artificial selection is a mechanism of evolution and is the main process of domesticating animals and plants for human use. Natural selection is the same as evolution.arrow_forwardSuppose it is possible to use genetic engineering to make people more intelligent. Do you think this should be allowed?
