Essay C. In class, we used the idea of levels of selection to explore why microbes make us sick, but do not kill us. Using the concepts of relative fitness, levels of selection, and strength of selection at each level, explain why viruses and bacteria commonly do not have such high virulence that they kill their host. In your explanation include four parts: (a) what trait was under selection, (b) the levels of selection involved, (c) how selection was acting on the trait at each level, and (d) the outcome for the trait overall from the interaction between selection at the different levels. (We also discussed how hosts can adapt to diseases, but don’t worry about that aspect for this answer)
