3. Darwin studied the finches on the Galapagos Islands. What discovery did he find within the species?

A. Darwin noticed the differences in their beaks. Finches that lived in areas with food sources of seeds and hard nuts had smaller beaks.

B. Darwin noticed the beak sizes of the finches and hypothesized that the finches that had dainty beaks flew back to the sources on the islands.

C. Darwin noticed the beak sizes of the finches and hypothesized that the finches with the dainty beaks could not fly high into the trees and could only feed off of food sources on the ground.

D. Darwin noticed the differences in their beaks. Finches that lived in areas with food sources of seeds and hard nuts had larger, stronger beaks.

Answer :

Final answer:

Darwin's study of the Galapagos finches revealed that beak size and shape correlated with the types of available food sources. Finches with larger beaks adapted to eat hard seeds and nuts, while those with smaller beaks fed on softer food like insects. This observation was crucial in developing the theory of natural selection.

Explanation:

Darwin's Observations of Galapagos Finches

During his voyage to the Galapagos Islands, Charles Darwin made significant observations regarding the finch populations residing there. He noted fascinating differences in their beak shapes and sizes, which varied based on the available food sources on the islands. This led to his hypothesis regarding natural selection.

Key Discoveries

Finches that inhabited areas with rich supplies of seeds and hard nuts tended to have larger, stronger beaks. These adaptations allowed them to efficiently crack open tough food items.
Conversely, those finches that had dainty beaks evolved to feed on different types of food that were more readily available, like insects or nectar.
Darwin's findings suggested that the beak shapes played a critical role in the survival and reproductive success of these finches, illustrating the concept of adaptation to environmental conditions.

This research fundamentally contributed to Darwin's theory of evolution, demonstrating how species adapt over time in response to their habitats.
