Answer 1

All the finches on the Galapagos islands are descended from a common ancestor and therefore related and rarely compete for the same food source.

Explanation:

All Galapagos finches descended from a common ancestor, making them related.
Because they evolved different beak shapes, they usually do not compete for the same food.
