A student is comparing the leg lengths of the rabbits in a population. She wonders if natural setection is occurring. She asks you to
evaluate her conclusions. Select ALL that are NOT supported by her data.
A)
The rabbits with medium length legs are the most stable and thus will out
survive the others.
B)
Medium length legs appears to be neither an advantage or disadvantage in
the current environment.
The rabbits with longer legs have a selective advantage that allows them
to survive and reproduce.
It is unlikely that evolution is occurring because none of the traits have
disappeared from the population
A predator is the likely source of natural selection in this population as the
rabbits with longer legs are more likely to escape compared with those
with the shorter legs
D)
E)
