How do Darwin’s finches illustrate adaptive radiation?

1.	How do Darwin’s finches illustrate adaptive radiation?
Answer» Darwin during his journey to Galapagos Islands observed that there were many varieties of small black birds later called Darwin’s finches. All the varieties he conjectured, evolved on the island itself. From the original seed-eating features, many other forms with altered beaks arose, enabling them to become insectivorous and vegetarian finches. This process of evolution of different species in a given geographical area starting from a point and literally radiating to other areas of geography (habitats) is called adaptive radiation.
