GENERAL KNOWLEDGE

Detailed explanation-1: -While visiting the Galapagos in 1835, British naturalist Charles Darwin observed local plants and animals. He became fascinated by species that seemed related to ones found on the mainland-but that also had many physical variations unique to different islands.

Detailed explanation-2: -They were first collected when the second voyage of the Beagle visited the Galápagos Islands, with Charles Darwin on board as a gentleman naturalist. Apart from the Cocos finch, which is from Cocos Island, the others are found only on the Galápagos Islands.

Detailed explanation-3: -Darwin’s finches are the emblems of evolution. The birds he saw on the Galapagos Islands during his famous voyage around the world in 1831-1836 changed his thinking about the origin of new species and, eventually, that of the world’s biologists.

Detailed explanation-4: -The Galápagos finches are a classic example of adaptive radiation. Their common ancestor arrived on the islands a few million years ago. Since then, a single species has evolved into different species that are adapted to fill different lifestyles.
