On the Origin of Species
Darwin had decided to call his book "An Abstract of an Essay on the Origin of Species and Varieties through Natural Selection", but with Murray's persuasion it was eventually reduced to the snappier "On the Origin of Species through Natural Selection". The full title reads "On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life", with races referring to varieties of domestic and wild organisms and not to human groups.
