What did Darwin discover on the Galapagos Islands?

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?

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.
