This is quite similar in some ways to my own theory that I posted recently at https://whatismusic.info/blog/HypothesisMusicWasALanguageSystem.html https://whatismusic.info/blog/HypothesisMusicWasALanguageSys..., because it postulates a sudden transition from non-recursive language to recursive language. The one difference in my theory is that I assume that the original non-recursive language was musical (with one tune equals one meaning). And musical language could not evolve into a more efficient and expressive recursive form of language - it had to be replaced.
