By Charles Darwin
Edited by David Quammen

Even the theory of evolution evolved. Charles Darwin's revolutionary insight that species originate and diversify through natural selection had a lineage stretching back to eighteenth-century naturalists such as Buffon and Lamarch. It was rooted in the geological studies of Darwin's friend and colleague Charles Lyell - and, especially, in the evidence the young Darwin accumulated as he traveled the world aboard H.M.S. Beagle.

This illustrated edition celebrates the 150th anniversary of the first publication of On the Origin of Species. Through hundreds of historical images and excerpts from The Autobiography of Charles Darwin, The Voyage of the Beagle, and The Life and Letters of Charles Darwin, it traces the debates that have raged since the 1859 publication and paints a compelling portrait of Darwin the scientist and the man.
