By: Charles Darwin (1809-1882)

On the Origin of Species by Means of Natural Selection by Charles Darwin On the Origin of Species by Means of Natural Selection

Considered to be one of the books that changed the world and how we view ourselves, On The Origin of Species by Charles Darwin was met with incredulous horror when it was first published in 1859. The revolutionary, almost blasphemous ideas it described were seen as antithetical to the existing ideas of Creation contained in the Bible and other religious texts. It was mocked, reviled and the author was personally subjected to vicious persecution by the establishment and theologians. In the years that followed its publication, the book became the subject of furious intellectual and social debate...

The Voyage of the Beagle by Charles Darwin The Voyage of the Beagle

Although Darwin revisited some areas during the expedition, for clarity the chapters of the book are ordered by reference to places and locations rather than chronologically. With hindsight, ideas which Darwin would later develop into his theory of evolution by natural selection are hinted at in his notes and in the book .
