If so then let's see the studies.
I can prove that UV has a bad effect on pyrimidines
with pyrimidine dimers - and that would favor
purines in what I suggest was a purine/hydrophilic
world, with a subset of pyrimidines/hydrophobic.
That would set up the genetic code.

Wait - what keeps it from burning up?
Wouldn't it more likely be more stable if it did that
then waste its time replicating dead ducks?

No No No.
You are on a quest to get to Darwinian selection
through replicators.
But there is no advantage in your scenario for
a single replication. So you have to settle
with flukes and black magic, and chance.

If there is no advantage in replicating no
molecule will do it.
Ex. If there is no advantage in turning purple
no molecule will do it - agreed?
Now replace purple with replication - same thing.
