→From Primordial Soup: update to new findings
===From Primordial Soup===
===From Primordial Soup===
John Sutherland from the University of Manchester, UK, has found the correct combination of primordial conditions for producing RNA. These findings may lead to a refinement of scientific theories related to the transition of natural nonbiotic molecules into the first elements of biological life.

From the paper entitle "Synthesis of activated pyrimidine ribonucleotides in prebiotically plausible conditions" in the peer-reviewed ''Nature'' journal, the authors document their methodologies. The scientists were able to repeatably create RNA structures from a joint precursors solution (pairing the bases and sugars in the molecule), a good blast of UV light, and 5 ingredients thought to be in abundance on the pre-biotic earth.
