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
Darwin observed a variety of species on the Galapagos Islands, including finches, tortoises, and mockingbirds. These observations were instrumental in his development of the theory of evolution by natural selection.
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.

Finches, amomg others...
Their beaks were adapted to match the foods they ate.
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.
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.
British Naturalist Charles Darwin visited Galapagos Islands in 1835. During his visit he observed that difference species were in a constant battle of survival with each other, and there was a variation in between tortoise on the sand and those in the water.
•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.
