That would explain the differences that he had noted in the finches that he had brought back from the Galápagos.” Not correct on two counts: In all, he [Darwin] shot six types of finches from three islands, and his samples from two of these were mixed together. he had tagged his specimens in a desultory manner and had rarely bothered to label by island. He remained confused by the Galápagos finches, believing that they fed indiscriminately together, unaware of the importance of their different beaks.
