ABC Science

When Charles Darwin visited the Galapagos Island in the 1800s, he observed many types of organisms that were similar but lived on different islands. The four species of mockingbirds found on the Gapapagos Island are shown below. Each species lives on a different island. These species are very similar, but the Hood mockingbird has a longer beak than the other three species. Which of the following best explains this difference?

• The hood mockingbird needs a longer beak for defense against predators.

• The Hood mockingbird originated from a different type of bird than the other species.

• The Hood mockingbird's longer beak is an adaptation to the food available in the bird's habitat.

• The Hood mockingbird's beak stretched to reach its food, and the longer beak was passed down to its offspring.
