they all evolved from one finch by natural selection.
a common ancestor
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)
It is thought that the finches have a common ancestor. Separated on different islands, each island eventually produced different finches.

No, evolution has created different species of finches on the Galapagos Islands. There are 15 different species that are found on the Galapagos islands.
Darwin realized finches on the Galapagos Islands were adapted to different regions
yes
The Galapagos Islands.
finches on the Galapagos islands, darwin noticed that on different island each beak of the finch was different depending on the food avalible on the different islands so darwin presumed that as each finch moved to these islands their beaks changed
