British biologist Charles Darwin (1809-1882) laid the foundations of the theory of evolution and transformed the way we think about the natural world. Few books have influenced human thought more than his On the Origin of Species. Published in 1859, it expounded his theory of natural selection, shocking society and revolutionized science.
