In contrast, populations of humans exposed to HIV for many years have not yet evolved significant resistance to HIV infection. Which of the following reasons may explain why evolution has been so much more rapid in HIV populations than in human populations? a) Humans have much longer generation times. b) Humans have reverse transcriptases that are less error prone. c) Human DNA polymerases are less error prone. d) Viruses need to mutate quickly to survive in their hosts. e) Humans have no ability to evolve resistance to HIV.
