Explanation:
The Hawaiian islands are extremely diverse in both flora and fauna species. Today, similarly to the Galapagos Islands, there are thousands of species of Hawaiian finches, some of them eat seeds, others fruit, while other nectar, etc. Also, their beaks and colors are incredibly variable.
After years of research, scientists determined that it was one finch progenitor that arrived from Asia to the Hawaiian Islands around 6 million years ago, which gave rise to this process of speciation. This situation, as suggested by the researchers, occured due to a phenomenon known as 'irruption', characterized by the movement of hundreds to thousands of birds from one region to another located very far.
This finch is suggested to have gotten carried away in a storm, which eventually brought it to the Hawaiian Islands.
