Darwin observed a variety of species on the Galapagos Islands, including finches, tortoises, and mockingbirds. These observations were instrumental in his development of the theory of evolution by natural selection.
The Galapagos Islands. About 600 miles due West of Ecuador.
Darwin was puzzled about the many adaptations of the finches on the Galapagos Islands

the animal Darwin examined were finches on the Galapagos islands (at least finches were the main thing he studied)
Galapagos finches
That they were evoled from on specie of finches.
The Galápagos Islands had finches that once shared a common ancestry. Darwin found that finches on one island had, over many generations, developed and adapted in differing ways to finches from other islands.
He observed the finches from the Galapagos islands, the mussels from the land lifted in Chile, the huge tortoises and dark lizards.
