The proposed revision is a tweak on RNA world:
Recently, Nobel laureate Jack Szostak’s lab made serious headway in answering the life origin question by publishing the first recipe for making a spontaneously self-reproducing gene in a 2020 Journal of the American Chemical Society paper…
These observations together point to a chemically functional role of ANAs [arabinonucleic acids] that would significantly increase the rate of RNA synthesis and stability in the environment of a primordial Earth. Szostak’s unusual addition to his recipe likely became the “secret ingredient” to making the most plausible RNA-filled gazpacho to date. And with that, the scientific debate around the origins of life on Earth keeps on simmering.Lauren Gandy, “Scientists have revised the recipe for the first gene and the origin of life” at Massive Science
Scientists revising their origin of life theories is—in the present climate—somewhat like fiction writers revising their novels. Nothing in the world wrong with it. But let’s be clear what level of real-world information we are talking about.
