It has to be said that this research is in its infancy

- Or perhaps just the researchers are.
and current hypotheses are nowhere near as solid as the Theory of Evolution
Which would put them somewhere between
Santa Claus and the Easter Bunny....

Please, don't draw us any more diaphrams.
Its the yeast you can do.

Oh brother.

Your 'self-replicating' molecule is a bust:

Rather than start with RNA enzymes - ribozymes - present in other organisms, Joyce's team created its own molecule from scratch, called R3C. It performed a single function: stitching two shorter RNA molecules together to create a clone of itself.
Further lab tinkering made this molecule better at copying itself, but this is not the same as bringing it to life. It self-replicated to a point, but eventually clogged up in shapes that could no longer sew RNA pieces together. "It was a real dog," Joyce says.
To improve R3C, Lincoln redesigned the molecule to forge a sister RNA that could itself join two other pieces of RNA into a functioning ribozyme. That way, each molecule makes a copy of its sister, a process called cross replication. The population of two doubles and doubles until there are no more starting bits of RNA left.
Its clear from the description that all it was able to do was join two specific half-RNAs (premade) together.

This molecule had no capacity to build itself from scratch out of neucleotides.

They had to provide an artificial 'soup' of half-beasts. When the supply runs out it stops. Thats obviously dead in the water in minutes, not a program that can run for 3.5 million years.

The main point is that the molecule CAN'T replicate itself.
It can only make a couple of lucky connections by being a landing-zone for half-pieces.

In the second place, crystals aren't compounds, they are just self-organizing surface structures that only work typically by submersion in a salt solution. You can get the same result in a room full of rubber balls at McDonalds.

Not at all. It only demonstrates self-repair, in a collective, communistic sense.

Not even one strand of RNA was manufactured out of singular nucleotides or other basic materials. Instead, conveniently, RNA strands were synthesized, broken in half, and repaired again by jostling them onto receptor-sites.

This isn't RNA generation at all, which is what "replication" would and should mean,
to a real scientist.

This is just RNA pre-synthesis and assembly.

The Analogy:

Its as if you had a favourite son who was a hopeless retard,
unable to fall out of a wheelchair, let alone tie his shoe:
So you build a thousand copies of the Eiffel Tower out of Lego.

Then you carefully break them exactly in half.
Now you pass two halves to your idiot-son,
and after a struggle, he manages to stick two halves together every few hours.
You keep it up until most of the towers are re-assembled.

Now you announce to the world that your idiot-son
can build the Eiffel Tower out of Lego
! You get him on America's Got Talent.
You aren't booed off the stage instantly,
because the whole crowd cries with you from pity and compassion.
No one dares shout "Fake! Fraud!"
Instead, everyone donates $10 to your favourite charity,
retarded children.

Oh yes, its a miracle! But not the kind you meant.
