Darwin's Finches

Why They're Cool: At first glance, these small birds don't look like anything special; there are at least 13 species of them in the Galapagos, all in varying shades of gray, brown and black. But they played a key role in scientific history. Charles Darwin's observation that there were similar, but not identical, species of finches on different islands led him to theorize that they'd evolved in isolation from a common ancestor. Today you can challenge yourself to identify the variations between species as you move from island to island.
