Which of the following statements accurately describes what we learned about HIV evolution?   a. HIV is more deadly in Northern Europe, but more transmissible in Africa. That is why there are more individuals infected with the illness in Africa.   b. HIV shares a most recently common ancestor with Simian Immunodeficiency Virus (SIV) such that SIV evolved as it host-switched from chimpanzees and gorillas into humans multiple times.   c. Drug development is exceedingly difficult because there are very few drug targets for HIV and AZT (a reverse transcriptase inhibitor) alone is the single most effective treatment for HIV.   d. Evolution of HIV virions within a person is quite slow such that a blood draw after 1 year of infection would reveal that every single virion would have the exact same sequence.
