A letter autographed by British naturalist-evolution theorist Charles Darwin has gone up for auction and is believed to fetch a record price. The note from 1865 went on sale on Friday at Sotheby's in New York; the online auction ends on December 9. Reportedly, Darwin wrote it to defend his theory of evolution, which was widely doubted by people and scientists at the time.
