Vedclass · Answer

(B) During his voyage on the ship $H.M.S.$ Beagle, Charles Darwin visited the Galapagos Islands.He observed a variety of small black birds, now known as Darwin's finches.He realized that there were many varieties of finches on the same island.He conjectured that all the varieties evolved on the island itself from the original seed-eating ancestors.From the original 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 radiating to other areas of geography (habitats) is called adaptive radiation.Therefore, Darwin's finches are a classic example of adaptive radiation.
