The Galápagos Islands are a series of islands in the eastern Pacific Ocean known as an archipelago. They are a part of Ecuador, a South American nation.
The Galápagos Islands are famous for their rich range of plant and animal life. Many species are endemic, meaning they can only be found in one place on the planet. And how did tortoises and birds differ among the islands of the galapagos?
Tortoises on Pinta Island, for example, had intermediate shells, while those on Hood Island had saddle-backed shells and those on Isabela Island had dome-shaped shells.
The Galapagos Island birds exhibited minor variances as well. Darwin discovered numerous species of little brown birds. Their beaks were all various shapes.
The tortoise in Isabela Island, on the other hand, has a shorter neck due to the luxuriant flora. Darwin was also interested in Galapagos finches.
He noticed some striking variances in the beaks of the birds dwelling on the various islands. Birds with longer beaks take seeds from fruits, whilst birds with shorter beaks consume seeds from the ground.

Various tortoise species resided on islands with different habitats, which Darwin discovered. He found the tortoises have characteristics that enabled them to thrive in their specific surroundings. Tortoises that ate vegetation close to the ground, for example, had rounder shells and shorter necks.
Domed tortoises, which reside in the colder sections of the archipelago, and saddle-backed tortoises, which live in arid, coastal habitats, are the two principal varieties. Saddleback shells contain a wide front hole that permits animals to access towering cactus by extending their necks.
The Galapagos finches, on the other hand, helped Darwin establish his theory of natural selection. Darwin’s Finches’ beaks were picked for their beneficial adaptations over generations until they all branched off to become new species. These birds have distinct beaks than mainland finches, although being almost similar in every other aspect.
