The Galapagos Islands are home to over 300 plant and animal species, such as cacti around 11 metres tall, marine iguanas, sea lions. The organisms are endemic to that particular island and its relatives on the other islands will have varying physical features. It is these organisms that gave Charles Darwin, who visited this island in 1835, the idea of natural selection, as their physical features are great evidences of many years of evolution.
