New Insight Into Possible Origins of Life

For the First Time Researchers Create an RNA Molecule That Replicates.

Experiment sheds light on the molecular evolution of RNA. Researchers at the University of Tokyo have for the first time been able to create an RNA molecule that replicates, diversifies, and develops complexity, following Darwinian evolution.​

Although there have been many discussions about this theory, it has been difficult to physically create such RNA replication systems. However, in a study published in Nature Communications, Project Assistant Professor Ryo Mizuuchi and Professor Norikazu Ichihashi at the Graduate School of Arts and Sciences at the University of Tokyo, and their team, explain how they carried out a long-term RNA replication experiment in which they witnessed the transition from a chemical system towards biological complexity.​

And if researches can do it, surely "Laws of Nature and of Nature's God" can do it, too.

Here's the previous paper that describes the RNA replication system this latest on is based on:

Its just adding to the objective credibility of RNA first hypotheses.

Implies in-parallel Darwinian evolution at the molecular level is possible, once different RNA molecules appear .. without necessary annihilation of all of them (via competitive resource depletion).

I also think the 'RNA' they started with, is derived from modern day (not pre-biotic) RNA(?)
