A rare first edition copy of Charles Darwin's "On the Origin of Species" was found on a bathroom bookcase in southern England. According to the Associated Press, it is one of about 1,250 copies printed in 1859. Christie's auction house will be putting it up for sale tomorrow ad expects that it will sell for £60,000. "It's a bit odd, though, that they put the book there and no one seems to have bothered to notice it for 150 years," says PZ Myers at Pharyngula. "I am really curious to know what other books were on that toilet shelf."
