  • Despite the fact that many data remain controversial and continue to be debated, over the past decades, there has been a remarkable advancement in our understanding of the processes that may have occurred on early Earth. The explosive influx of new geological, geophysical, and geochemical data allowed proposing terrestrial, atmospheric, and aquatic conditions, which favored the emergence of life. Investigating the history of our planet and the origin of life is the most fascinating scientific field. This research field allows us to understand who we are and how humans evolved from simple life forms. Redox reactions played significant roles in geological and biological evolution of Earth. The abiotically occurring redox reactions contributed to the formation of the Earth’s atmosphere and oceans, driving geochemical cycles of redox-active elements and the synthesis of organic molecules, leading to the origin and evolution of life. The dominant theories of the origin of life are based on redox reactions, which could have occurred in the Hadean atmosphere, deep-ocean, and shallow waters emphasizing the crucial roles of minerals and energy sources. allowing these reactions to proceed. The first life forms probably emerged as early as between 4.1 and 3.8 Ga, at the boundary between the Hadean and Archean eons. However, it was during the Hadean eon known as the early Earth, that atmospheric and aquatic conditions were favorable for the first organic synthesis. Based on recent advances in the field, some hallmarks of the origin of life on early Earth can be distinguished. The Hadean atmosphere was likely slightly oxidizing with dominance of CO2, H2O, and SO2; however, CH4, NH3, and HCN could have been delivered to Earth by meteorite impacts, and transient reducing atmosphere could have existed during the Hadean eon. Moreover, meteorite could have delivered transition metals such as iron and organic compounds from extraterrestrial sources. Atmospheric composition and reactions and oceanic processes influenced each other, and the Hadean environments could have created conditions that favored redox reactions. Geothermal gradient created in hydrothermal systems provided energy, fueling organic synthesis underlying both Oparin-Haldane heterotrophic theory and mineral by chemoautotrophic Wächtershäuser. surface-based proposed theory The first organic molecules necessary for the synthesis of the building blocks of life could have been formed in various environmental settings including the atmosphere, deep-ocean hydrothermal vents, and terrestrial shallow waters such as lakes, ponds, and hot springs. These environments utilized different energy sources such as UV radiation, volcanic activity, lightning, and geothermal heat. Depending on the availability of elements and energy sources, each environmental setting may favor the formation of specific organic molecules. However, these compounds could have been transported between different environmental settings for further processing. Therefore, life could have emerged in multiple interplayed environments, which allowed for diverse organic molecules to converge, eventually leading to self-replication and life. There are two contrasting principles: “metabolism-first” and “gene first”, each with its own controversy. The “metabolism-first” principle’s controversy is that an early network of metabolic chemical reactions could not be sustainable without programmed replication-based genetic instructions. The “gene-first” principle’s controversy is that, for the formation of genetic molecules such as RNA, thermodynamically stable and selfreplicating systems could not have emerged under severe conditions on early Earth. However, these two principles are not completely exclusive and can be reconciled because metabolic processes are necessary for the synthesis of nucleotides, which are the building blocks of RNA and DNA. It is probable that both metabolic pathways and the genetic system are evolved in an interdependent manner. Heterotrophs and autotrophs could have originated through synchronizing evolutionary paths, and therefore both heterotrophic and chemoautotrophic theories of the origin of life may complement each other. According to chemoautotrophic theory of the origin of life, carbon fixation from CO2 using mineral surfaces in early Earth’s hydrothermal environments relies on reactions of reduction by H2 produced with the involvement of Fe2+ or H2S. This includes exergonic and thermodynamically favorable reductive metabolic processes such as the WLP and rTCA, which could prebiotically produce precursors for building blocks of proteins and nucleic acids. These metabolic cycles are considered as self-sustaining chemical systems, and organic molecules produced in these processes could be consumed by first heterotrophic organisms.

  • Open questions and promising research directions Several open problems can now be read as designable experiments. One is continuity across steps, which boundary conditions allow activated substrate generation, oligomer assembly, and copying to co-occur without mutually exclusive requirements, and with net accumulation across repeated cycles (Pressman et al., 2015; Ding et al., 2023; Muñoz-Velasco et al., 2024; Vázquez-Salazar, 2026). A second is system-level selection, how compartment type, exchange rates, and spatial structure shift parasite control and effective error thresholds, even when copying fidelity remains modest (Higgs and Lehman, 2015; Vaidya et al., 2012; Papastavrou et al., 2024). A third is catalytic breadth.

  • The paper's axial transport framework and pure time formalism are applied to explain biological boundary formation and proto-cellular emergence, but no empirical datasets from origin-of-life chemistry experiments, clay surface chemistry, or lipid assembly kinetics are cited to validate whether the predicted cost minimization and gradient-driven boundary closure actually occur in measurable timeframes and concentration regimes.
