A Fully Emergent Proto-Genetic System Arising from Prebiotic Earth Conditions: A High-Resolution Global Simulation

This study presents a full-scale planetary simulation of early Earth conditions, demonstrating the spontaneous emergence of metabolic networks, compartment-forming vesicles, and a proto-genetic coding system from purely physical and chemical rules. The model integrates realistic ocean chemistry, atmospheric composition, ion gradients, catalytic microdomains, UV flux cycling, hydrothermal inputs, and competitive protocell dynamics across more than 500,000 degrees of freedom. Without introducing any biological assumptions, the system self-organized into: a stable 55-node global attractor, coherent long-range chemical field structures, replicative protocell behaviour under competition, proto-codon mapping driven by energy minimization, and a reproducible structural blueprint with predicted physical properties. The results offer new computational evidence that metabolism-first and coding-first emergence pathways can coexist and reinforce each other under realistic prebiotic conditions. This work suggests that early Earth may have naturally supported the rise of organized chemical networks far more readily than previously assumed. This simulation represents one of the most detailed and high-resolution computational explorations of prebiotic evolution and the origin of life, offering new testable hypotheses for astrobiology, prebiotic chemistry, and systems biology.
