The life and times of Lonesome George

Lonesome George, the last of the Pinta island giant tortoises and a conservation icon, has died of unknown causes. He was believed to be about 100 years old. He was found in 1972 and become a symbol of the Galápagos Islands. His species helped Charles Darwin formulate his theory of evolution in the 19th century
