english: Darwin had only written: “Light will be thrown on the origin of man and his history.”
non_english: Bhí an-éileamh ar an leabhar, On the Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life (On the Origin of Species is ea an leagan giorraithe a dtugtar air de ghnáth), agus ní rabhthas ag súil leis an éileamh sin.
