A supermyth is a myth that is entrenched (supported) by another related myth.
The myth that Charles Darwin (1858/59) originated the theory of "process of natural selection" independently ff Patrick Matthew's (18310 "natural process of selection" and that each used the same four words to name it is supported by the myth of Charles Darwin being incredibly honest.
The supermyth was busted some years ago (e.g. Sutton 2017). Then in August/September 2023 Artificial Intelligence (ChatGPT and others) have scanned the new Big Data and other findings in the literature to conclude that Darwin lied about the prior readership of Patrick Matthew's (1831) book 'On Naval Timber and Arboriculture' and the bombshell original ideas in it.
