Brief introduction: The Medium Ground Finch Geospiza fortis, is one of species of finches first collected by Charles Darwin on the Galapagos islands, and as such it is called one of Darwin’s finches. It is emblematic for its involvement in the development of evolutionary theory by Darwin and for supporting the hypothesis of natural selection.
