Darwin's finches
In virtually every biology textbook, Darwin’s finches are quoted as a key proof of the theory of evolution.

For example: ‘It was, however, the diversity of adaptive structures shown by the 13 species of finches found within the archipelago which had the greatest influence on Darwin’s thinking on the mechanism of the origin of species’ (Biological Science 1&2, Taylor Green & Stout, 1997, Cambridge University Press).
