Suppose a population of rabbits is introduced to an environment that has both extremely hot summers. The rabbits in this population have a range of ear sizes.
Small Ears
Medium Ears Large Ears
Rabbits lose a lot of their body heat through their ears. Every summer, more of the short-eared and medium-
eared rabbits die than the large-eared rabbits.
At first, there are an equal number of rabbits with each size of ears. After several years, there will be more rabbits with
large ears than either of the others. This is an example of ___
A Stabilizing selection
B Disruptive selection
