If they put Darwin’s book in, they should use his full original title:
On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life
And on the back cover, put endorsements from Hitler and Marx.
“Origin” is so turgid and dull it would put your motel reader right to sleep. “The Descent of Man and Selection in Relation to Sex” is much better. (That book always reminds me of Disco for reasons including that was the time I read it.)
