-Are the Galapagos finches and those on the mainland the same species?
Explanation:
- When Darwin visited the Galapagos islands he observed that the small flocks of finches that existed there were very similar to the finches that existed in the mainland of South America except for their beak shape and feeding habits.
- This prompted him to ask the question that 'Are the Galapagos finches and mainland finches the same species?'
- Later on studies made it evident that a few groups of mainland finches migrated to the Galapagos island and occupied different niches.
- They adjusted themselves to the island environment and evolved with new adaptations in beak structure and feeding habits.

- The Galapagos finches are divided into three groups: the ground finches, tree finches and Warbler finches.
