1. We have seen how the genetic diversity within a tumor can be
used to estimate the tumors history.

a. In what ways is this similar to the process of
reconstructing the evolutionary history of organisms? In what ways is it
different?

b. Do the genetic traits we use to reconstruct a tumors history
need to be selectively neutral? Why or why not?

2. Pathogens require a minimum population size of potential hosts.
If the host population is too small, in a short time the entire population has
either been killed by the pathogen or has survived the initial infection and
become immune. If

2. Pathogens require a minimum population size of potential hosts.
If the host population is too small, in a short time the entire population has
either been killed by the pathogen or has survived the initial infection and
become immune. If this occurs, the pathogen dies out. What evolutionary changes
in a pathogen might increase its ability to survive in a smaller population? For
example, measles requires a host population of about 500,000 humans, while
diphtheria can get by with only about 50,000 humans. Develop some hypotheses
for why diphtheria can survive with just one-tenth the number of hosts. For
example, how might these two diseases differ from each other in transmission rate,
virulence, latency to infection, or mutation rate?
