Darwin realized finches on the Galapagos Islands were adapted to different regions
No, evolution has created different species of finches on the Galapagos Islands. There are 15 different species that are found on the Galapagos islands.
That the finches were similar to the ones on the mainland, but had adapted to the island environment.
Their beaks were adapted to match the foods they ate.

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
Darwin hypothesized that the different finches on the Galapagos islands all had a common ancestor due to their similarities, but had evolved different beak shapes and sizes to adapt to different food sources on the islands.
The species of finches Darwin found were so varied because they had migrated over time to islands of different vegetation, and they adapted to better suit their new environment. Over time, the finches became so different from each other that they turned into new species.
