प्रश्न
Describe one example of adaptive radiation.
Advertisements
उत्तर
This process of evolution of different species in a given geographical area, starting from a point and literally radiating to other areas of geography (habitats), is called adaptive radiation. Darwin’s finches represent one of the best examples of this phenomenon. Another example is Australian marsupials. A number of marsupials, each different from the other evolved from an ancestral stock, but all within the Australian island continent. When more than one adaptive radiation appears to have occurred in an isolated geographical area (representing different habitats), one can call this convergent evolution.
