Galapagos islands are a group of volcanic islands in the Eastern Pacific ocean, about 1000 km from South America. Thirteen species of finches are found on the islands; they resemble each other closely but differ in their feeding habits and in the shape of their beaks. Assuming that an ancestral stock of finches came from the mainland, what is the most likely explanation for the existence of similar but distinct species of Galapagos finches

1.  Finches developed different kinds of beaks in order to feed on different kinds of food.

2.  Finches evolved separately according to the habitate in which they settled.

3.  Finches from the mainland bred with a resident population of a related species and produced new genotypes.

4.  Finches underwent convergent evolution to produce very similar species.
