Answer 1

The most accurate explanation for the characteristics of Darwin's finches is:

All finch species evolved from a common ancestor.

This reflects the concept of adaptive radiation, where different species evolve from a common ancestor to adapt to various niches and environmental conditions, leading to the diversity in beak size and shape observed among the finch species.
