Vedclass · Answer

(A) Darwin observed that there were many varieties of finches in the same island. 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. This phenomenon provides evidence for the origin of species by natural selection,as different beak shapes were selected based on the availability of food resources in their respective niches.

The diversity in the type of beaks of finches adapted to different feeding habits on the Galapagos Islands,as observed by Darwin,provides evidence for:
