Zoology - Evolution Question with Solution | TestHub

Darwin's finches are small birds that were first observed by Darwin at Galapagos Islands during his voyage in his ship H.M.S. Beagle. Darwin noticed that all the islands had these small finches which were very similar except for their diverse beak shapes. This was surprising for him and so Darwin observed these birds and thus came to the conclusion that beak shapes were different because of their different feeding habits and the habitat. Thus the finches got adapted to the new habitat and habits. This is adaptive radiation. This was also an example of divergent evolution as according to Darwin these finches being similar had a common ancestor but due to habitat changes got adapted separately. Hence these finches are examples of adaptive and divergent evolution.
