Detailed explanation-1: -Solution : When more than one adaptive radiation appear to have occurred in an isolated geographical area and two or more groups of unrelated animals come to resemble each other for similar mode of life or habitat, it is called convergent evolution.
Detailed explanation-2: -In fact, many classic examples of adaptive radiations involve islands or lakes; notable examples include Darwin’s finches of the Galapagos, honeycreeper birds and silversword plants of Hawaii, and cichlid fish of lakes Malawi and Victoria in Africa.
Detailed explanation-3: -Adaptive radiation, if occurs twice in a geographically isolated area will have a similar result, that is the evolved species will have similar adaptations suitable for the area. Hence, it will be a case of convergent evolution.
Detailed explanation-4: -So, the correct option is ‘Convergent Evolution’
