Answer:
A population of rabbits with
white, tan, and brown fur
lives in a habitat
with few predators.
A new species of hawk
that preys on rabbits
is introduced to the
habitat.
The hawks have more success
in catching rabbits with
white fur because they are
easier to see in this habitat.
The next generation of
rabbits has a higher
proportion of individuals
with tan and brown fur.
The rabbits with white fur
mutate so their fur
is tan or brown.
The founder effect decreases
the number of rabbits
with white fur in
the population.
