One of the most influential scientists of world history, the naturalist Charles Darwin gained widespread fame and notoriety with the 1859 publication of 'On the Origin of Species'. At first shocking his Victorian readers by suggesting that animals and humans shared a common ancestry, Darwin's theory of evolution by natural selection became the foundation of modern evolutionary studies. For the first time in publishing history, this comprehensive eBook presents Darwin's complete works, with numerous illustrations, rare texts appearing in digital print for the first time, informative introductions and the usual Delphi bonus material.
