Answer 1

The correct explanation that accounts for the characteristics of Darwin's finches is:

All finch species evolved from a common ancestor.

This statement aligns with the concept of adaptive radiation, where species evolve different traits (such as beak size and shape) to adapt to various ecological niches in their environment, originating from a single ancestral species.
