A new theory, via Phys.org:
“Even if you believe in a RNA-only world, you have to believe in something that existed with RNA to help it move forward,” said Ramanarayanan Krishnamurthy, associate professor of chemistry at TSRI and senior author of the new study. “Why not think of RNA and DNA rising together, rather than trying to convert RNA to DNA by means of some fantastic chemistry at a prebiotic stage?”
But wouldn’t the confluence of DNA and RNA point to design? Anyway, why do w only hear of the problems with RNA world (“fantastic chemistry”) when some other theory that won’t work is being promoted?
