Brian Ford has written two articles on Darwin's lack of originality on the the theory of evolution by natural selection (here and here). Most importantly, in his 1971 book 'Nonscience' Professor Ford writes (p. 142) on how some scientists are famous not for their genuine originality but for hoodwinking the world they were genius originators simply because they published on a bombshell breakthrough at the most timely - "what Ford names Fashonistic" - time:
'Charles Darwin used much the same kind of ploy too, by writing his thesis at exactly the most Fashionistic time, when everyone was discussing it. He wasn't the first to propose his particular interpretation, of course, but his use of Fashionism and the clothing of the argument in detailed observations of animals in general made the whole project an obvious winner."
What Professor Ford does not write, but which is perfect support for his 'Fashionism' argument is what Matthew wrote to Darwin and the entire world in a published open letter of May 12th 1860 in the Gardeners Chronicle and Agricultural Gazette (p 433): that his work was read and cited but that many feared to cite it - including an eminent professor - and that it had been brute censored (see Sutton 2017 p. 111 for the fully referenced details). In that and in an earlier published letter of April 1860 Matthew clearly told Darwin and the world that the world was not ready for his theory in 1831 when it first appeared in print.
