"which statement best describes the method used above to determine the evolutionary relationships between three species of finches?
(1)examine the structure of the beaks and compare them.
(2)observe behavioral and physical characteristics of all the finches and group them by similarities.
(3)obtain molecular evidence from all three species and identify similarities.
(4)compare common ancestors of all three of the species to see if they are the same."
