Answer:

Darwin's finches were one of the examples of adaptive variation. On Galapagos islands, we can observe the total 15 types of finches species. The beaks of finches were evolved according to the surrounding and there eating habits. The differences were acted upon by natural selection and resulted in the evolution of the finch species, which led Darwin to his theory....

The most important differences between species are in the size and shape of their beaks, which are highly adapted to different food sources. The birds are all dull-coloured.

A long term study carried out for more than 40 years by the Princeton University researchers Peter and Rosemary Grant has documented evolutionary changes in beak size affected by El Niño/La Niña cycles in the Pacific.The favorable adaptations of Darwin's Finches' beaks were selected for over generations until they all branched out to make new species. These birds, although nearly identical in all other ways to mainland finches, had different beaks.
