The Origin of Species by Means of Natural Selection by Charles Darwin

Date of Publication: 1883

First published in 1859, this controversial scientific work is considered to be the foundation of evolutionary biology.

It introduced the scientific theory that populations evolve over the course of generations through a process of natural selection.  Darwin included evidence that he gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation. #1163
