Zoology - Evolution Question with Solution | TestHub

The finches of Galapagos islands provides evidence in favour of biogeographical evolution.

All the varieties of the finches, Sir Darwin conjectured, evolved in the island by 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.
