The traditional paradigm of biological evolution often frames nucleic acids as metabolic adaptationsdeveloped within functional prokaryotic cells. This paper presents a counter-theoretical synthesisdemonstrating that Ribonucleic Acid (RNA) represents a universal, pre-biological chemical phenomenon thatpredated protocellular compartmentalization and the Last Universal Common Ancestor (LUCA). Bysynthesizing abiotic organic synthesis principles, stoichiometric equilibrium models, and Assembly Theory(), we demonstrate that RNA selection is a thermodynamically driven deterministic process. Protocells,operating as semi-living entities with rudimentary metabolism and devoid of refined genetic regulation,inherently contained self-replicating catalytic RNA (ribozymes). Furthermore, the presence of fully functionalRNA transcription and translation machinery in LUCA confirms that nucleic acid information encoding wasstabilized long before cellular diversification. Epistemologically, this supports the view that life's chemicalsubstrates are universal invariants rather than localized, shifting paradigm constructs.
