    Darwins finches provide an excellent evidence in favour of organic evolution. These are related to which of the following evidences?

    A)  Embryology

    B)  Palaeontology (or fossils)

    C)  Anatomy

    D)  Biogeography (or geographic distribution)

    Correct Answer: D

    Solution :

                    Biogeography is the study of the geographical distribution of life forms on earth. Darwin undertook a voyage on the ship HMS Beagle to the Southern Hemisphere, where life is most abundant and varied. Along the way, Darwin found different forms of life very different from those in England. Towards South America, he found that similar species replaced each other. He thought that related species could have been modified according to the environment. His views got confirmed on Galapagos Islands, where he found different modified forms of finches which seemed to have descended from mainland finches as a result of the natural selection.
