Q. 18

Darwin on his voy

Answer :

On his voyage to the Galapagos Islands, Darwin saw many varieties of finches in the same island. There were the original seed eating finches but some among them had altered beaks and they became insectivorous while others became vegetarian finches. He concluded that different groups of finches had adapted to their geography and hence developed traits that best suited survival in that given geographical area. This process of evolution starting from a point and radiating to other area of geography or habitat is called adaptive radiation.
