Answer» This process of evolution from or formation of a number of divergent species from a common ancestor at a single point and in a given geographical area and the new species adapting, spreading or radiating in different directions is called adaptive radiation. Darwin'explained the phenomenon of adaptive radiation on the basis of his investigation of the basis of fauna of Galapogas islands Finches of Galapogas island offer the best example of adaptive radiation. During his journey, Darwin went to Galapogas island, and observed, that there were many varieties of finches in the same island. They varied from normal seed-eating ones to those that ate insects. Another example of adaptive radiation is evolution of the Australian marsupials from a single ancestor. |
