Why did the finches on the different Galapagos Islands have different beak shapes?

Over time, the birds with beak shapes that allowed them to eat the cacti would survive over others.
The offspring had to recieve a recessive allele for the trait from both parents.
Different beak shapes allowed for bird to eat specific types of foods. The most successful on each island was most common.
The hares who did not grow white fur in the winter would stand out and be more easily eaten by predators.
Genes are located on chromosomes and are inside the nucleus.

Birds live on an island that recently had a drastic change in climate. These birds get their water from eating berries. Rainfall has decreased and plants with berries and seeds have died off only leaving cacti. What might happen with this bird?
