Illustration of Charles Darwin showing an ape how alike the pair of them are. Darwin (1809-1882) suggested that natural variation in a species creates a wide range of individual characteristics some of which are more useful than others. The competition to survive in nature provides adriving force for evolution in the form of natural selection, a mechanism which weeds out those individuals possessing traits less suitable to the environment. The implications of his theory to man's own origins fuelled a bitter controversy with the church. Image taken from an unnamed artist in The London Sketch Book, 1874.
