Question

A ) Finch species have similar diest

B ) All Finch species envolved from a common ancestor

C ) Finch species interbreed

D ) Each Finch species envolved from a different ancestor

Answer 1

The best explanation for the similar features and differences in beak size and shape among Darwin's finches on the Galapagos Islands is:

B) All Finch species evolved from a common ancestor.

This option aligns with the concept of adaptive radiation, where a single ancestral species diversifies into multiple forms that adapt to different ecological niches, which is what has happened with Darwin's finches. The variations in beak size and shape correspond to different feeding habits and environmental adaptations.
