Of original 600 handwritten pages of Charles Darwin’s On The Origin Of Species (1859), all but 45 have been lost. Those that remain were used as doodle pads by his kids.
As Darwin Manuscript Project director David Kohn says: “Darwin was done with those pages — he was throwing away sections of his draft and not caring about it because the book was published.”
Last Friday was the 206th anniversary of the naturalist’s birth.
