There was no need to cleanly synthesize RNA early on to get the materials that life ended up with. While no known living microbe or creature has a chimeric genome, one research team has artificially created E.
And yeast and other microorganisms have been observed to accidentally make such mixtures, though they have enzymatic systems that eliminate such mistakes. Krishnamurthy and Bhowmik applied their chimeras-first concept to another system, too, with mixtures of RNA and TNA, an artificial nucleotide often used to model what might have come before the RNA world.

In fact, a handful of other studies have already shown additional benefits to this approach, popularly known as systems chemistry. In , Krishnamurthy, Hud and their collaborators showed that trying to understand the origins of polypeptide synthesis by focusing only on amino acids, the building blocks of peptides, might be the wrong tack. Studies from the past couple of years have shown that complexity wins out over purity in other contexts, too: Vesicles built out of fatty acids alone, for instance, are less stable than those formed from a combination of fatty acids and certain salt compounds.
Sutherland has found evidence, for example, that the early prebiotic mixture might have involved RNA and peptides, rather than RNA and DNA: Reactions that produce the building blocks of RNA inevitably generate peptide building blocks as well.

He now wants to explore further consequences of this kind of chimeric chemistry. Prometheus is a systems and service monitoring toolkit that collects metrics from configured targets at given intervals, evaluates rule expressions, displays the results, and can trigger alerts if some condition is observed to be true.
