Darwin's Finches Were Not All Finches
A finch is a small seed-eating songbird. The famous Galápagos finches that shaped evolutionary theory belong to a different family.
A finch is a small seed-eating songbird with a stout conical beak. Darwin's finches are the textbook case of adaptation, with beaks shaped for different foods on different islands — but they are not true finches: modern classification places them among the tanagers. The name stuck from the nineteenth century and is now too famous to change. Darwin himself did not label his specimens carefully by island, and the pattern was reconstructed later.
