The explanation that best accounts for the characteristics of the 13 species of Darwin’s finches on the Galapagos Islands is:

All finch species evolved from a common ancestor.

This idea aligns with the concept of adaptive radiation, where species diversify from a common ancestor and adapt to different ecological niches, resulting in variations such as beak size and shape.
