<< Maybe circa 3.8 billion years ago, but any record of such early
principles-in-action has been entirely overprinted by subsequent life.

It's romantic to think that, within some relict "microbial Galapagos" there
may still exist some primordial population of cells with only catalytic,
self-replicating RNA's to do their tricks with...

No no no no no. Stop right there. First tell me
why it has to be SELF replicating?
Would an environmentally induced replication
through heat that lasted for a million years not
work? IMO that was what happened - the self
part was a late edition.

A post of mine today talks of a paper that talks about
this very thing - an environment cycle pushes
a PCR type replication on paired RNA.

Dump the self in self replication - replace
it with environmental replication, then we can
talk.

And PS, an environmentally induced replication,
can be recreated without ribozymes.
