darwin claimed that the differences in the beak formation between the varieties of finches species found on the galapagos islands was related to their

a: migration pattern

b: food source

c: genetic body size

d: time of reproduction

the answer is B, the change in the finches beaks depended on their food source, some had long slender beaks for catching insects, while others had more sought beaks for eating seeds found on he ground. This is a text book example of natural selection ( the selection of traits by nature that best fits the environment for survival)

i think that d. wind is the answer.   i missed the question when i answered a. currents.
