Galapagos Finches and Genetic Relatedness

APBIO-UEEW1V

The finches that populate the Galapagos islands are genetically much more closely related to a species of ground finch found on the mainland in South America than they are to a species of finch found on the mainland in North America.

This observation suggests that

A

the finches on the Galapagos islands have descended directly from the finches in South America.

B

the climatic environment on the Galapagos islands is more similar to the climatic environment in South America than North America.

C

the Galapagos islands were once physically connected to the continent of South America.

D

the finches on the Galapagos islands and the finches on the mainland of South America are experiencing convergent evolution.
