3. How were the finches that lived different than the finches that died?
4. How/why were the finches that lived able to survive?
5. How did natural selection play a role in changing the finches’ average beak size? (before 9:41)
6. How did finches with different beaks become different species?
7. What keeps different species of finches from mating?
