Answer 1

I just took the test and made a 100% the answer is C. lack of competition

Answer 2

The correct answer is C. lack of competition. It was exactly the opposite, the competition caused them to adapt and change their beak shape and size in order to be more proficient in getting food. This is what he described in his theory on how finches speciated and became genetically different from other finches similar to them.
