Final answer:
Ecuador owns the Galápagos Islands where Darwin developed his theory of evolution. These islands are home to unique species and ecosystems that played a crucial role in Darwin's observations on natural selection, influencing his evolutionary theory.
Step-by-step explanation:
The country that has the Galápagos Islands, which significantly contributed to Charles Darwin's theory on evolution, is Ecuador. The Galápagos Islands are noted for their remarkable biodiversity and unique species that greatly influenced Darwin's ideas on natural selection.
Isabela is the largest of these islands, where Mount Azul can be found. When Darwin visited the Galápagos Islands during his voyage on the HMS Beagle, he observed various species, including 13 different types of finches, that exhibited distinct traits adapted to their specific habitats.
These observations led to his groundbreaking work on the theory of evolution, where he postulated that species evolve over time due to natural selection.
