For at least $675,000, you can own a handwritten page from Charles Darwin's manuscript of 'On the Origin of Species'

If you are among the scant 33% of U.S. adults who believe that humans and other living things evolved solely by a process of natural selection, it might be time to put your money where your mouth is. No, this is not a political fundraising pitch. It's a notice of the impending sale, by auction, of a piece of scientific history -- a signed manuscript page from the concluding chapter of Charles Darwin's "On the Origin of Species." Written in the compressed, right-slanting script of Darwin himself, the sheet is numbered "245" in the upper right-hand corner, and would go on to become page 514 of the latest, 3rd edition of his landmark tome. It was likely written in 1859, when the English biologist was about 50 years old.
