The method used above involves the determination and comparison of the genes of the three species of finches. So, the answer is
<span>(3) Obtain molecular evidence from all three species and identify similarities.
</span><span>The genetic makeup of the three species will show different similarities that can be used to relate the evolution of the different species.</span>
A series of steps designed to solve problems and answer questions is "a scientific method".
