Darwin, Charles


English naturalist and geologist born in Shrewsbury, Shropshire (1809-1882). While serving as naturalist aboard HMS Beagle, Darwin developed his theory of evolution through natural selection based on his detailed observations of species, most famously, the variety of finches. He published his theory in 1859 in his book On the Origin of Species. His other works include The Descent of Man, and Selection in Relation to Sex and The Expression of the Emotions in Man and Animals.
