Want this question answered?
they all evolved from one finch by natural selection.
Darwin studied the beak of a finch to see how it adapted to the food it ate. hope it helps, good luck!! ;)
The statement that Charles Darwin came to realize that organisms of the same species are identical is false. Charles Darwin observing the finch population in the Galapagos discovery quite the opposite was true. The finch has branch off with many adaptation to suit the changes in the different environments.
Darwin noticed that every island had its own kind of finch
Darwin observed that on the island, there were many finches, but each one of them were slightly different.Darwin noticed that beak shapes and sizes differed among the finches. This led him to believe that finches evolved differently in response to different environments.The variation in beak size and body size that showed, at a latter date, that all of these birds he thought were vastly different species (wrens, warblers and such ) were one ancestral finch species adapted to many different niches on the many different Islands of the Galapagos.
right
different finch populations that appeared closely related
Charles Darwin discover the finches in Galapagos in 1831. He noticed that the finches beaks were different compared to the finch's in Ecuador.

the galapagoes 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
The Galapagos Islands.
