Charles Darwin Honored With A Very Long, Thin Sculpture

To honor the 200th birthday of the great naturalist and the 150th anniversary of On the Origin of Species, London’s Natural History Museum has inlaid on a ceiling the cross-section of an entire 200-year-old oak – 17 feet long and 5 mm thick. Artist Tania Kovats says she was inspired by Darwin’s tree-of-life diagram.
