Explanation:
The large finches living on the Galapagos islands are different from the original source population from a nearby islands because of the following reasons -
- A natural selection favored only the large finches because they are more fit to the current environmental conditions.
- A genetic drift has been occurred in the two populations living on the nearby islands.
- Due to the separation of habitat on both the islands, the gene flow between the two islands is reduced.
All the above listed reasons are responsible for the difference in the finches found on the two islands.
