Charles Darwin Publishes the Theory of evolution Charles Darwin was a naturalist he found on the voyage He saw He studied plants animals and animals few people had seen their environments He lived during In the Galapagos Islands of South the 1800s in the United Kingdom America he made some of his most He came from a family of scientists important findings He noted many Both his father and grandfather were differences within a species of bird doctors They were also interested Darwin believed the differences in studying the world around them Darwin developed the same interests As a boy Darwin noticed the DARWIN S TORTOISES differences among bugs he found He collected samples He learned While Darwin was in the how to observe species A species is a group of living things that all share the same features Darwin earned a spot as a scientist Galápagos Islands one of the species he observed was the Galápagos tortoise These huge creatures weigh almost 500 pounds 230 kg and live very long lives They regularly live for more than 100 years The oldest on record lived to be on a ship at the age of 22 The ship set sail in 1831 It was a nearly five year voyage aboard the HMS Beagle He went all around 152 That means tortoises born the world He observed the plants and animals O when Darwin visited in 1835 likely outlived him by more than 50
