Article published in April edition of the journal Natural Chemistry[url=https://www.nature.com/articles/s41557-019-0225-x][/url] provides evidence that both DNA and RNA can form spontaneously from naturally available precursor molecules. This suggests the prevailing RNA world hypothesis for abiogenesis is needlessly complex. Life organized to pass genetic information with both RNA and DNA as all known life on earth do now could developed spontaneously directly from organic precursors, and did not require a convoluted intermediate step.
