What did Darwin discover on the Galapagos Islands?
In Galapagos he found a remarkable population of plants, birds and reptiles that had developed in isolation from the mainland, but often differed on almost identical islands next door to one another and whose characteristics he could only explain by a gradual transformation of the various species.
Why was Galapagos island ideal for studying evolution?
“Galápagos are a wonderful place to study evolution, still, because, remarkably, several islands and their inhabitants are close to being in the fully natural state, with little or no influence of human activities,” says the evolutionary biologist and Princeton University professor emeritus Peter Grant who, with his …
What did Darwin observe about organisms in South America and Galapagos?
Darwin observed that beak shape varies among finch species. On these islands, Darwin observed species of organisms on different islands that were clearly similar, yet had distinct differences.

What is Galapagos famous for?
The islands are known for their famously fearless wildlife and as a source of inspiration for Darwin’s theory of evolution. And that’s just part of the story. Born of fire: The Galápagos Archipelago is one the most volcanically active areas in the world.
What led Darwin to the theory of evolution?
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
