> I haven't checked, and apparently neither has anyone else. Wait, how did you figure that out? Of course this has been checked. Here’s a review: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4446746/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4446746/ Anyway, the tl;dr is that, at best, very short RNA fragments would survive being digested in vertebrates (but most likely not even that). This doesn’t preclude the transfer of information by RNA via food but it severely limits it. Also, to reiterate the point I’ve made elsewhere: RNA is unstable and short-lived and therefore unsuitable as a long-term memory carrier. It can act as a short-term carrier under specific circumstances (and that’s arguably its main function in the cell anyway).
