Re: Diversification of self-replicating molecules
So the questions remain:

do we have self-replicating molecules? No
did they "evolve" and diversify into two different types of self-replicating molecules? No
does this "evolution" show the possibility of life's beginning? No

Inquiring minds want to know ... Which ones?

Ones not in denial of the evidence, of course. People with open-minded skepticism and no preconceptions.

Enjoy

Re: Update --- have self-replicating molecules become life?
... which means that there are plenty of possible routes to some kinds of molecular evolution occurring throughout the universe. But this doesn't do much to address how genetic-code-based life emerged on early Earth.

Exactly. Baby steps, chemical reproduction first, then more complex structures (when does the cell membrane come in to the picture? I see it as a mechanism to concentrate chemical reproduction reactions).

Enjoy
