How are the results of this simulation an example of evolution? (Choose the best answer.) a. The results are an example of evolution because evolution on a genetic level, is a change in the frequency of alleles in a population over a period of time. b. The results are an example of evolution because at the end of the experiment there is more bunnies with fur than bunnies without. c. The results are an example of evolution because over time the furless bunnies are dying off, while the bunnies with fur are able to reproduce.
What is a. The results are an example of evolution because evolution on a genetic level, is a change in the frequency of alleles in a population over a period of time.
