Summary Introduction
To review:
The human populations would likely evolve differently in areas of the world where HIV infection rates are high.
Introduction:
The genes (heritable traits) are passed from the parents to their offspring. The traits give identity to an individual. Few traits are required for the survival. Some genes undergo evolution for the better survival of the individual. The individuals with evolved traits produce offspring having the same traits. Thus, the frequency of such traits increases in a population and this leads to evolution.

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.
Use Figure 2 to answer the following
Circle the common ancestor of HIV in Central Africa
According to the Bite, the researchers compared only a small portion of the DNA sequence of each HIV strain, not the entire sequence. Why do you think they did that?
The media has recently reported that a high number of patients while staying in the hospital, are gettinginfections caused by antibiotic-resistant bacteria. Using evolutionary theory, explain how this could occur.

- As people use more of an antibiotic, the number of bacteria that are resistant to that antibiotic increase. Which statement describes a mechanism behind this trend? (A.) People’s bodies become more resistant to antibiotics after exposure to them (B.) Antibiotic molecules get weaker over time due to natural selection (C.) The antibiotic kills sensitive bacteria, and any bacteria resistant to it multiply to take their place (D.) Bacteria take up antibiotics and integrate them into their own DNAarrow_forwardLook carefully at the picture below and you will see an insect called a katydid.
