The essence of the Galapagos Islands — a Darwin’s finch atop a marine iguana. There are fifteen different species of Darwin’s finches, and they were instrumental in the development of Charles Darwin’s theory of evolution by natural selection. This particular bird is called a medium ground finch — not to be confused with the small or the large ground finch. All three ground finches (and for that matter all Darwin’s finches) are roughly the same size. The difference is in the beak — each beak having evolved in a slightly different manner thanks to the different food sources on the different islands. Likewise, as I mentioned in an earlier post, the iguanas are also slightly different depending upon which island they inhabit.
