Adaptive radiation is the process of evolution of different species in a given geographical area starting from a point and radiating to other habitats.Darwin went to Galapagos islands and observed that there were many varieties of finches in the same island. All the varieties evolved on the island itself. Darwin reasoned that after originating from a common ancestral seed eating stock, the finches must have radiated to different geographical areas and undergone adaptive changes in their beaks enabling some to become insectivorous.
What is adaptive radiation? How did Darwin explained this process of evolution?
