Detailed explanation-1: -The most studied animals on the Galápagos are finches, a type of bird (Figure below). When Darwin first observed finches on the islands, he did not even realize they were all finches. But when he studied them further, he realized they were related to each other. Each island had its own distinct species of finch.

Detailed explanation-2: -The Galapagos Finches or Darwin Finches are among the most renowned species in the world within the study of evolution.

Detailed explanation-3: -2. What did Charles Darwin study in the Galapagos Islands? The most famous fauna of the Galapagos Islands are the iguanas, giant tortoises and finches.

Detailed explanation-4: -There are 13 species of Darwin’s finches found in the Galapagos Islands, which are famous for their evolutionary history.

Detailed explanation-5: -Darwin’s finches, inhabiting the Galapagos archipelago and Cocos island, constitute an iconic model for studies of speciation and adaptive evolution. A team of scientists has now shed light on the evolutionary history of these birds and identified a gene that explains variation in beak shape within and among species.
