The first edition of Charles Darwin's On the Origin of Species, published on November 24, 1859 in London by John Murray. It is a seminal work in scientific literature and a landmark work in evolutionary biology. It introduced the theory that populations evolve over the course of generations through a process of natural selection.

British naturalist Charles Darwin -- who expounded the theory of evolution by natural selection, the principle that launched a scientific revolution -- based this survey on his personal observations. Many of his findings were proven by later research, and today's behavioral scientists continue to draw upon this work for both knowledge and inspiration.
