The finches include 15 species of passerine birds which were studied by Charles Darwin and helped him derive the ground-breaking theory of natural selection. Based on the adaptations Charles Darwin observed in finches and tortoises in the Galápagos, he wondered if species living on different islands had once been members of the same species. The Galapagos Islands are home to the largest living species of tortoise in the world. The name of Charles Darwin and his famous book the Origin of Species will forever be linked with the Galapagos Islands.

These small animals are usually found in the colder areas of the Galapagos, mainly on Fernandina Island and Isabela Island, and tend to live in caves or crevices.. - Darwin in a letter to his cousin William Darwin Fox Charles Darwin 's scientific career is rooted deeply in geology. While in the archipelago, Darwin focused as much on geology as on biology, collecting many geological specimens. For example, giant tortoises, marine iguanas and even the Galápagos penguin. On islands with humid highlands, the tortoises are larger, with domed shells and short necks; on islands with dry lowlands, the tortoises are smaller, with "saddleback" shells and long necks. The headquarters for the foundation is the Charles Darwin Research Station and is used to conduct scientific […] These islands and the surrounding waters are home to some of the most unique wildlife on the planet, including giant land tortoises, marine iguanas and blue footed boobies.

Galapagos penguins are special because they are the only penguin species that is found north of the equator.
