The Galapagos Islands comprise an archipelago of 13 major and about a hundred smaller islands in the Pacific Ocean, off the coast of South America's Ecuador.It was a study of the biodiversity of the species of these islands that gave rise to the famous scientific theory of evolution through natural selection by Charles Darwin. This was the journey that carried the naturalist Charles Darwin on expedition to South America and the Galapagos Islands. Natural Selection: Charles Darwin & Alfred Russel Wallace Repeated volcanic eruptions helped to form the rugged mountain landscape of the Galpagos Islands. Due to this volcanic formation, the islands are characterized by many steep slopes, with heights ranging from a few meters above sea level to more than 5000 feet above sea level. This explains why members of the dandelion family (Compositae) are found throughout Galapagos. They also have a very long lifespan, and can live to be over 100 years old.
