Evolution Natural Selection and Adaptations

What most likely caused the finches on the Galapagos Islands to have beaks that were different from the finches on the mainland?

• There were different types of predators on the islands.

• The finches on the mainland could not fly high enough.

• There was no water on the islands.

• There were different food types on each island.

The fur of the snowshoe rabbit changes to a lighter color in the winter. This allows the rabbit to blend in with its surroundings. This change is an example of:

• Adaptation

• Extinction

• Competition

• Succession
