Hello John Sullivan,
My thesis is as follows: the common nature of these aspects of life on a molecular level is very strong evidence that they only originated once & evolved as life did. We do not see the existence of entirely dissimilar genetic or metabolic systems that would illustrate entirely separate origins.
Do a search on "RNA World" ... it appears the best explanation to date is that RNA evolved chemically and out-competed other systems for self-replicating molecules, but then DNA evolved chemically and took over.
Some old threads of mine on this topic are Panspermic Pre-Biotic Molecules - Life's Building Blocks (Part I) and Self-Replicating Molecules - Life's Building Blocks (Part II) -- they are both old and there has likely been much discovered since.
... as proof of ...
Do you prove theories in chemistry? I know it works in math, but generally in science it seems we develop theories as the best known explanations rather than prove them.
Can we ever prove that life evolved chemically from molecules or are we limited to developing the best explanation based on the evidence we know and the known behavior of chemicals?
Enjoy

Re: Natural processes are uniformitarian?
The only time we see a high level of uniformity in the chemical and morphological makeup of things is when those things are man (intelligent) made.
Gosh I didn't know salt crystals were intelligently made ....
I always thought they were self organizing molecular structures that built themselves according to chemical processes.
OMG -- LOOK at all these signs of intelligence!!!
Enjoy

Re: Natural processes are uniformitarian?
..,.according to chemical processes.
And just who do you think determined those chemical processes?
Deist god/s are one possibility, but not the only one.
... True enlightenment resides in the process, not the substance.
Leaping to concussions gives you headaches rather than answers.
