How Darwins ideas evolved
Two computer screens display images of the first edition copy of Charles Darwin's "On the origin of species" in London on Thursday. About 90,000 pages of manuscripts, field notes, photographs, and sketches connected with Charles Darwin are being placed online, where they can be viewed free. Among the gems are his first formulation of the theory of natural selection, his first written doubts that species were fixed and touching correspondence from his wife on religious faith.
