Darwin : in a nutshell

"Peter Whitfield explains how Darwin came to his revolutionary views following his voyage on the Beagle and his initial reluctance to publish his findings."@en
"Charles Darwin, father of evolution, was one of the greatest pioneers in science. His five-year voyage on The Beagle, his visit to the Galapagos Islands, his careful work in noting small differences of fauna on different islands - all led to the concept of natural selection, which radically changed the way mankind and the animal world was viewed.
