Each of the species of finches on the Galapagos Islands has its own distinctive beak and ecological niche.
<h2>Reason :</h2>
Darwin observed that the finches evolved thanks to the difference in their habitat. Consistent environmental differences in several habitats on different islands in the Galapagos, the supply of different foods sources (seeds, cactus, insects, and fruit) promotes directional selection on resident finches for optimal beak morphology which maximizes survival under local conditions.
This process has produced more distinct species of finches, all unique to the archipelago. He noticed that every finch species is having a different type of beak, counting on the food available on its island.
