What did Darwin discover?

natural selection

What is Darwin Theory?

Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others stating that all species of organisms arise and develop through the natural selection of small inherited variations that increase the individual’s ability to compete survive and reproduce.
