Darwin Finches

Darwin's finches

Darwin's finches are a group of species of different birds that are related to each other by the investigative findings that Charles Darwin obtained during his journey on the Beagle. There are 13 species that live on the Galapagos islands and one on the Coco island. They all have the same size between 10 to 20 cm. The curious thing lies in the shape and size of the beak, the same ones that are adapted to different food sources.

Likewise, these small birds are famous throughout the world as they are a visible example of the process by which, from a single species, several have been formed depending on the characteristics of the environment in which they have lived. In the case of Darwin's Finch, the ancestral species from which the 13 species of Galapagos arose, no longer exists.
