arise relating to the prebiotic availability of DAP and other amidophosphosphorus species on the earlyearth. Herein, we demonstrate that DAP and other amino‐derivatives of phosphates/phosphite are generated when Fe3P (proxy for mineral schreibersite), condensed phosphates, and reduced oxidation state phosphorus compounds, which could have been available on earlyearth, are exposed to aqueous ammonia

Abiotic synthesis of ribonucleotides, mainly at the 5′ position, from the corresponding ribonucleosides within guanosine:borate hydrogels in the temperature range of 70–90 °C, using urea and a phosphate source (K2HPO4 or hydroxyapatite).
