I suggest that slightly before the RNA world
there was a world that consisted of
1. mostly purine RNA strands
(dimers ruled out most pyrimidine coding)
and
2. mostly hydrophilic amino acids.

And it was because both of these groups
were far in the majority of molecules present,
that there developed a

purine/hydrophilic world where mostly purine
codons 
(for numerous reasons as mentioned elsewhere)

were matched with mostly hydrophilic amino
acids.

"Biological chemistry is wet chemistry. Most of
the chemical reactions that occur in life involve
solutes dissolved in water." Strickberger.



Thus if correct this better defines part of
the RNA world development.
