In the finches, Charles Darwin observed the different beak shapes according to where they lived in the Galapagos. He later linked their beak shapes to the food they ate. Their beaks were shaped to make it more convenient to get their food. In tortoises, he observed the shapes of their shells. The shell shapes got either progressively curvier or progressively less curvy as you travel up or down the island. And I'm not 100% sure about the theory thing, but I think it's the Theory of Evolution
Charles Darwin noticed that the iguanas in one region where different than the iguanas in another region
he wondered if all were different
He observed the finches from the Galapagos islands, the mussels from the land lifted in Chile, the huge tortoises and dark lizards.
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.
different finch populations that appeared closely related Charles Darwin, while on the Galapagos Islands, studied finches and their beak structure as their ability to eat fruits, nuts and bugs.
The Galapagos Islands. About 600 miles due West of Ecuador.
Charles Darwin bred pigeons to test his theory of evolution through natural selection. By selectively breeding pigeons with specific traits, he was able to observe how variations in a population could be passed on to the next generation.
•The overall observations he made were Survival of the Fittest. He observed the finches beaks from the mainland and from the islands. He realized that finches were all the same species, however they adapted in their own special way.
Galapagos (gu LAHP uh Gus)
Finches looked alike, but ate different things.
