An English naturalist born on 12 February 1809. He established that all species of life have descended over time from common ancestors, and proposed the scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.

He died on 19 April 1882 when he was diagnosed with what was called “angina pectoris” which then meant coronary thrombosis and disease of the heart. At the time of his death, the physicians diagnosed “anginal attacks”, and “heart-failure”.
