The archipelago known for its biodiversity studied by Charles Darwin is the Galápagos Islands. Located off the coast of Ecuador, these islands are famous for their unique wildlife and ecosystems, which played a crucial role in the development of Darwin's theory of evolution by natural selection. The Galápagos Islands feature a variety of species, some of which are found nowhere else on Earth. Today, the islands are a UNESCO World Heritage site and a popular destination for eco-tourism.
