What makes finches in the galapagos islands a good example of speciation? a. galapagos finches are not matched to their environment. b. galapagos finches do not have to compare for shelter. c. galapagos finches teach each other new adaptations. d. galapagos finches have developed different beak adaptations

The correct answer is -

D. Galapagos finches have developed different beak adaptations.    

Darwin studied finches on galapagos island, which developed different adaptations ( in terms of their beak sizes and shapes) due to the availability of different food ( seeds in varying size).

With due course of time, these birds evolved into different species.

Thus, option D) is the right answer.

thinking it would be d not too sure but i think it's right
