A shortened form of the self-splicing ribosomal RNA intervening sequence of Tetrahymena thermophila has enzymatic activity as a poly(cytidylic acid) polymerase [Zaug, A.J. & Cech, T.R. (1986) Science 231, 470-475]. Based on the known properties of this enzyme, a detailed model is developed for the template-dependent synthesis of RNA by an RNA polymerase itself made of RNA. The monomer units for RNA synthesis are tetra- and pentanucleotides of random base sequence. Polymerization occurs in a 5'-to-3' direction, and elongation rates are expected to approach two residues per minute. If the RNA enzyme could use another copy of itself as a template, RNA self-replication could be achieved. Thus, it seems possible that RNA catalysts might have played a part in prebiotic nucleic acid replication, prior to the availability of useful proteins.
Poissonian RNA Polymerization
Here we consider a cycle of RNA polymerization by randomly adding activated monomers to an oligomer as a Poisson process, taking an experiment on clay surfaces18 as a model case. Non-RNA nucleic acid analogues may have carried genetic information before the RNA world emerged1, but the formulations below can also be applied to such cases. Let xl be the abundance of l-nt long oligomers. After the injection of activated monomers at the time of initialization (t = 0), evolution of xl is described by the following differential equations:
x˙l+1=κ xl−κ xl+1 ,
(1)
where the dot denotes a time derivative. Here we assume that the coefficient κ (probability of a reaction with a monomer per unit time) does not depend on the oligomer length, which is approximately consistent with the trend found in the experiment18. We consider initial conditions of xl = 0 for l ≥ 2, and x1 can be approximated to be constant in the early phase. The second term on the right hand side can be neglected when xl+1 ≪ xl. Solving the equations iteratively under these conditions, the abundance xl at a time t is obtained as
xl=pl−1r(l−1)! x1,
where pr ≡ κ t is the reaction probability with a monomer up to the time t. A similar result is obtained by considering the Poisson distribution with an expectation value of pr; the only difference is a factor of exp(−pr) that is not important at pr ≲ 1. We should consider only the regime of pr ≲ 1, because by the time t ~ κ−1, a significant fraction of activated monomers are lost by the reactions, and hence the approximation of constant x1 is no longer valid and efficient polymerization is not expected beyond this point. If activated monomers are lost earlier by some other processes (e.g. hydrolysis), pr would be smaller than unity.
In RNA oligomerization on clay surfaces, the coefficient κ should be proportional to the concentration of activated aqueous monomer concentration of ~ 0.01 M (=mol/L adsorbed on the clay surface. This clay-phase monomer concentration increases with that in aqueous phase, but according to the Langmuir adsorption isotherm, it saturates when the adsorbed monomer abundance reaches that of the exchangeable cations on clay surface. In the experiment18, montmorillonite has 0.8 mmol exchangeable cations per gram, and it starts to saturate at an aqueous monomer concentration of ~ 0.01 M (=mol/L). At the saturated clay-phase monomer concentration, the reaction rate is κ ~ 1 h−1, and thus pr ~ 1 is reached within a few hours, which is much shorter than the hydrolysis time scale of activated monomers. Aqueous monomer concentration needs to be higher than a certain level to keep κ large enough for pr ~ 1, and this may be achieved at some points during a cycle, for example, by variable amount of water expected in dry-wet cycles around warm little ponds29.

This might be your worst attempt yet. Do you even read these papers you post? You are embarrassing yourself
"Here we consider a cycle of RNA polymerization by randomly adding activated monomers to an oligomer as a Poisson process, taking an experiment on clay surfaces18 as a model case."
'model case' means they didn't actually conduct a physical study. It is theoretical. I know it's tough figuring out that santa claus (abiogenesis) isn't real, but someone has to break it to you eventually. Since RNA or amino acid monomers do not self-polymerize, the random-chance theory is bunk
Pod Mrcaru, for example, had an abundance of plants for the primarily insect-eating lizards to munch on. Physically, however, the lizards were not built to digest a vegetarian diet.
Researchers found that the lizards developed cecal valves—muscles between the large and small intestine—that slowed down food digestion in fermenting chambers, which allowed their bodies to process the vegetation's cellulose into volatile fatty acids.
"They evolved an expanded gut to allow them to process these leaves," Irschick said, adding it was something that had not been documented before. "This was a brand-new structure."
The lizard also dropped some of its territorial defenses, the authors concluded. Such physical transformation in just 30 lizard generations takes evolution to a whole new level, Irschick said. It would be akin to humans evolving and growing a new appendix in several hundred years, he said.
"That's unparalleled. What's most important is how fast this is," he said.

I assume this is your way of conceding that nucleotide monomers do not self-polymerize. Especially in water.
This ruins the possibility of abiogenesis.
Therefore, Your nihilist world has no possible avenue for life to come to be through random chance. It's over. You can continue living your faith in nothing, but never call it science.

I assume this is your way of conceding there has never been any actual scientific study of the divine, such as specimen analysis and taxonomic classification and genetic decoding? Because that would require a physical substance to measure. Like polymers & enzymes that have zero indication of divine meddling.

So is your God actively rewriting the Covid virus variants right now? I mean, the theory of evolution easily explains the new variants we’re seeing.
Are you saying your god or intelligent designer is actively writing code to kill us?

Ahh yes, because the genetic code doesn't give you a good enough hint that there is a Coder.
I love how every time you are faced with the futility of evolutionary theory and abiogenesis, you resort to attacking other's beliefs. If your belief in evolution had any strength whatsoever, you wouldn't have to resort to such cowardly tactics. The fact that evolutionary theory is wrong is good news, it means you guys can leave behind the dead-end theory and begin seeking real knowledge.

Because pestilence wasn't a part of the original model, it is related to our choice to deviate from the source code.
