Which of the following accurately describes natural selection? A) Natural selection acts on pre-existing variation in a population. B) Natural selection occurs when individuals shift to a different phenotype better suited to their novel environment. C) Populations become better adapted to novel environments as individuals with beneficial phenotypes reproduce more than others without that phenotype. D) Two of the above are correct. E) All of the above are correct.

Question 10 2 pts Why does coevolution not occur in commensalism relationships? O a. Natural selection has little or no effect because selection pressure is only occurring in one direction (1.e. only one of the two species in the relationship is exerting selection pressure). O b. Both species in the relationship are harmed causing at least one species to go extinct, therefore natural selection is not able to occur. O c. Abiotic factors prevent the occurrence of coevolution in commensalism...

D Question 14 2 pts Natural selection will not occur in a population over time if All individual variation is due to environmental factors. The environment is changing at a relatively slow rate. The population size is large. The population lives in a habitat where there are no competing species present Besides Darwin, who else proposed a concept of natural selection?

In a sentence or two, describe why variation in a population is so critical to natural selection. If a population didn't have any variation (all individuals were genetically the same), what might happen to that population?
