  The words of Charles Darwin?  No; these are the words of John Sebright, penned in The Art of Improving the Breeds of Domestic Animals in 1809, the year of Charles Darwin’s birth and fifty years before On the Origin of Species was published. Darwin refers to this passage in Notebook C of his Species  Notebooks.[13]   It will be noticed that Sebright is not discussing domestic selection, but is quite clearly saying that processes leading to differential survival and reproduction in nature will have ‘all the good effects of the most skilful selection’. Darwin, then, did not need to read Malthus to see what is here so plainly and clearly stated—namely, that the struggle for survival in nature will have the same ‘selective’ effects as the actions of the domestic breeder of plants and animals.
