There are 13 species of Darwin's finches on the Galapagos Islands. They have many similar features but differ in beak size and shape. Which explanation accounts for these characteristics? (1 point)

Question

• Finch species interbreed.
• All finch species evolved from a common ancestor.
• Finch species have similar diets.
• Each finch species evolved from a different ancestor.

Answer 1

The explanation that accounts for the characteristics of Darwin's finches, including their similar features and differences in beak size and shape, is:

• All finch species evolved from a common ancestor.

This statement reflects the concept of adaptive radiation, where species diversify from a common ancestor to adapt to different ecological niches, leading to variations such as beak size and shape based on their feeding habits and environments.
