How many finch species did Darwin send to the British Museum?
13 distinct species of Galapagos finches were identified
Since Darwin found many species of plants he found many species of finches. Those species, just like the warbler finch, were found on 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
Geographical Distribution of living species supports evolution because, as species are split up along the planet, they endure changes which better help they adapt to their surroundings. An example of this is with the Finches in Darwin's studies on the Galapagos islands. They all came from the same breed of finch but branched off with different characteristics to survive on the different islands that they were surviving on.
Genetic isolation. This occurs when members of species that also occur on mainland areas begin to evolve slightly different habits and appearances.
The variation in their beaks that allowed the finches to utilize a great variety of foods. Darwin saw this and though that these birds were different species and did not know better until he returned to England. There it was revealed to him that the birds were all finches and that lead to evolutionary concepts.
Darwin used the wide variation of beaks to support his theory of evolution. He speculated that all the different finches had descended from one species and were not different species.
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 discovered that the finches were once the same species. Due to isolation, each island produced variations of the original finch species.
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.

One example is the cichlid fish in the African Great Lakes. They have evolved into numerous species with diverse body shapes and feeding strategies to exploit various niches in the lakes, such as herbivores feeding on algae or predators preying on other fish. This adaptive radiation showcases how a single ancestral species can give rise to multiple specialized forms through evolution.
different finch populations that appeared closely related
Since Darwin found many species of plants he found many species of finches. Those species, just like the warbler finch, were found on the Galapagos Islands.
Darwin was the man who went to the Ga'lapagous Islands and studied the finch's beaks and how they all differd even though they were all apart of the same species.
Charles Darwin discover the finches in Galapagos in 1831. He noticed that the finches beaks were different compared to the finch's in Ecuador.
These are finches; Darwin noticed the variation on the Galapagos Islands and the Beagle's captain, Robert Fitzroy, was able to supply details about the various birds on each island. Darwin noticed that the finches had beaks adapted to different types of food; some strong to crack nuts, others fine to pick up seeds. Darwin asked a crucial question; if a single species of finch had arrived at the Galapagos, how could you end up with several different species? This was key to the idea of natural selection.
When Darwin traviled from island to island and saw that each one had its own specialized finch... there are 13 types to be exact ...this suggested to him that animals evolved
