Adamic RNA World[edit]

Most likely Adam was constructed by RNA only but Eve completed the DNA double helix and from then on it was all DNA. I'll let ya know for sure when I get to heaven by faith in Christ.

Please update with: "A prebiotically plausible scenario of an RNA–peptide world"[edit]

I think it would be good to add some brief info about this to the article and/or the article abiogenesis. It's currently featured in 2022 in science like so:

Scientists close a missing link in the potential origin of life from a RNA world – synergistic formation of peptides and ever-longer RNAs or peptide-decorated RNA, leading to a protein world.^[1]^[2]

Concerning the first reference used there: the paper didn't say it helped grow "ever-longer RNAs" or did it?
Another thing that may be good to clarify is whether there were separate peptides, normal RNAs and peptide-decorated RNAs or just a few of those. The paper is so unclear about it, it may obvious/self-explanatory to some but I haven't read all of the study just to find that out.

Loads of prebiotic molecules found in Milky Way?[edit]

FWIW - (For being aware only of newly published relevant studies - not necessarily to incorporate into the main article) - On 8 July 2022, astronomers reported the discovery of massive amounts of prebiotic molecules, including for RNA, in the galactic center of the Milky Way Galaxy.^[1]^[2] - Stay Safe and Healthy !! - Drbogdan (talk) 13:09, 10 July 2022 (UTC)Reply[reply]
