As time passed the Finches continued to evolve and contributing factor for this was environmental changes. Many of the Finches that lived on the islands died because of various diseases that affected the land.
Finches have many predators including owls, foxes, snakes and many more however at the moment Finches are being preyed on my Parasitic Flies.
Environmental changes are not all bad for the Finches survival. This is because it helps the finches evolve and to able to survive, thrive and reproduce.
These Finches are still adapting right now and will continue to a adapt and evolve creating a wider variation.
