Origin of Life and a RNA World- Only in the Imagination
Ever since RNA was found to be a catalyst the "RNA World" was imagined. In the imagination the "RNA World" grew and prospered. However in the real world it withered and died. The imagination paid no heed.
How/ why did this alleged RNA World wither and die? Well in all cases of any self-sustained replication of RNAs or with self-replicating RNA ligases, the products did NOT undergo Darwinian evolution. That is the products did what the original did, even if the products contained variations:
A self-replicating ligase ribozyme
All of the chemical self-replication systems that have been described, including the ribozyme-based system of the present study, are not capable of undergoing Darwinian evolution.
That is also true of Joyce's more recent experiment involving a self-sustained replication of RNAs. Nothing new evolved.
Ahh but the materialists do not need no stinking evidence. They have their imagination. And in their imagination RNA does evolve new functions and can even intergrate with amino acids and polypeptides to form ribosomes which can then crank out more polypeptides.
Unfortunately ribosomes do not appear to be reducible to matter and energy. I say that because synthesized ribosomes- made up of the same matter and energy as ribosomes in living organisms, do not function. Even if we just synthesize the RNA component the ribosome refuses to function as the ribosome in living organisms.
Why is that so? I say it is due to programming- as in the ribosomes of living organisms are programmed to crank out certain polypeptides. And the program, as with information, is neither matter nor energy.
So the bottom-line is if any RNA World existed it existed in the designer's lab.
