The Galápagos Islands was where Charles Darwin theorised on the science of evolution.
Darwin.
Darwin determined that animals on the Galapagos Islands showed variations in their physical characteristics that were suited to their specific environments. This observation contributed to his theory of evolution by natural selection, as he realized that these adaptations allowed the animals to survive and reproduce in their unique island habitats.
share a common ancestor and have evolved to adapt to different ecological niches on the islands. This observation provided evidence for Darwin's theory of evolution by natural selection.
Darwin inferred that the origin of species was through evolution, or adaptions according to changes in lifestyle, climate, et cetera.
Charles Darwin made his most important observations on the Galapagos Islands, specifically on islands such as Santiago, Santa Cruz, and Isabela. These observations influenced his theory of evolution by natural selection.
Darwin noticed that each island in the Galapagos had its own unique species of finches with different beak shapes. This observation inspired his theory of natural selection and evolution. Darwin also noted variations in other species, such as tortoises and mockingbirds, among the different islands.
