Different finch species have beaks of different shapes and sizes. What do these beak differences tell us? Different finch species have beaks of different shapes and sizes. What do these beak differences tell us? Different finch beak shapes are evidence that individual birds changed their beaks so that they could feed efficiently. Different finch beak shapes are evidence that all Galápagos finches share a common ancestor. Different finch beak shapes are evidence that finch species adapted to different environments over many generations. Different finch beak shapes are evidence that several finch species with different beak types came to the Galápagos Islands from the mainland.

The correct answer is C. Different finch beak shapes are evidence that finch species adapted to different environments over many generations.

Explanation:

According to Charles Darwin's proposals related to evolution, organisms that are similar such as birds or finches adapt to environmental conditions over time which explains the differences in terms of the phenotype (observable traits). This occurs in the case of finches beak shapes, as Darwin studied around 15 species of these birds in the Galapagos Islands and found finches have different sizes and beak shapes that were linked to the type of food each species consume and the source of this. Therefore, different finch beak show "that finch species adapted to different environments over many generations".

Different finch beak shapes are evidence that finch species adapted to different environments over many generations.
