What accounts for the large number of different species of finches that Darwin observed on the Galapagos Islands?

The varying local conditions on each of the islands. Each group of finches was bred, through natural selection, to have the characteristics that would optimize finch survival on that island. For example, an island might have a unique food source, say a type of nut, so the finches that had more robust beaks and could break these nuts more easily got to eat more food, survived more often, and could provide for their young better, so over time they became more numerous on the island while the less fit ones declined in number until only finches with robust beaks were left. This is the basics of the idea.

Charles Darwin
What did Darwin wonder about the finches and tortoises?
Charles Darwin reached the Galapagos islands in 1835. He observed many finches, tortoises and many other animals. He observed that the animals in the Galapagos were different than the animals in other places like south America. This may be because the climate is different in the Galapagos than in other places so the animals may have involved to suit the temperatures in the Galapagos.

Charles Darwin's observations were quite interesting. For instance he observed that the animals of the Galapagos Islands were different from other animals.
