Charles Darwin was born in 1809. He originally trained as a doctor but was more interested in nature, so he was better known as a ‘naturalist’ (someone who studies animals and plants). Darwin was a religious man.
In 1831 Darwin set off on a journey around the world which lasted 5 years. This trip is commonly known as the ‘Voyage of the Beagle’ (the name of the ship which Darwin travelled on). On his voyage, Darwin collected specimens of animals, plants and rocks from around the world and sent them back to England.
He also kept a journal of his observations. Darwin noticed that there were similarities between different species of animals and plants.
