Darwin's hand-noted On the Origin of Species up for auction
A copy of 'On the Origin of Species' with handwritten notes by English naturalist Charles Darwin is going on sale at Christie's, a UK-based auction house. Christie's has put an estimate of Â£300,000-Â£500,000 (â¹2.5 crore-â¹4.3 crore) on the annotated book, which it said will allow "for the first time a precise reading of Darwin's exact revisions without... reconstruction and translation".
