The life that exists on Earth today likely arose from a single common ancestor. Judge each statement below and select the ones that explain how natural selection has played a role in the diversity of life on Earth from that single ancestor. Select all that may apply.
A Natural selection acted on phenotypes that were the result of new mutations in a population.
B Natural selection reduced the species numbers on a global scale since individual organisms did not mutate quickly enough.C Natural selection maintained the fitness of populations on a global scale, which maintained species numbers at a constant level.
D Natural selection acted on isolated populations separately, allowing for those populations to diverge over time, allowing for speciation.
E Natural selection increased the fitness of certain populations as traits that were considered adaptations became more prevalent in the population.
