Core Proposition This study establishes that the extreme cold and arid stress within the 35°–40° N latitudinal belt constitutes a necessary condition driving cognitive leaps in archaic humans. Concurrently, the climate-independent hydrological refugium unique to the East Asian Yellow River Basin—forged by a stable cratonic basement coupled with deep-fault water conduction—serves as the sufficient condition sustaining population persistence and continuous evolutionary succession. The strict coupling of these two factors defines the necessary and sufficient conditions that rendered East Asia the core evolutionary forge, thereby fundamentally refuting the single-factor fallacy underlying the Sinai Corridor model. Molecular clock outputs lacking physical extreme calibration generate mathematically consistent yet environmentally implausible evolutionary timelines. Both the Sinai terrestrial corridor and the Red Sea maritime passage fail to sustain late Pleistocene hominin dispersal under rigorous glacial and interglacial climatic constraints. Thermodynamic and chemical physiological thresholds impose non-negotiable survival limits on human migration routes; thus, while molecular algorithms produce divergence date estimates, these values collapse when substituted into the hydrological boundary conditions of late Pleistocene arid zones. Physical natural laws remain invariant, irrespective of genetic modeling results. Calibration across multi-disciplinary constraints indicates that northern mid-latitude seasonal stress zones constitute the most consistent, geologically verifiable driver for sustained hominin cognitive evolution, rather than the narrow, intermittently viable migration corridors that have dominated prior narratives. Author’s Self-Assessment The LSED framework is presented as a testable, falsifiable alternative to the Sinai Corridor out-of-Africa dispersal model. Its core mechanistic claims are structurally constrained by three binding empirical commitments, which separate this hypothesis from unfalsifiable narrative models of human origins: (i) Falsification boundary: Deep drilling within the Yishu-Liaokao fault zones must recover continuous MIS 4–2 travertine/travertine-related authigenic mineral archives paired with cold-period stable isotope signals; failure to recover such sedimentary records directly invalidates the hydrological refuge sufficiency condition, dismantling the core coupled tectonic-climate-evolution logic. (ii) Quantitative exclusion standard: The forthcoming Global Exclusivity Matrix serves as a multivariate discriminant analysis toolkit. Isolated qualitative counterexamples, anecdotal regional paleoanthropological sites, or single-variable analogies cannot overturn the framework’s exclusivity argument—contradiction requires complete, standardized multivariate scoring of competing cratonic regions matching the matrix’s input dimensions. (iii) First-order physical boundary constraints: All renal/thermal physiological veto calculations rely on fundamental human thermodynamic survival thresholds. Cultural/behavioral buffering (water storage, shelter, seasonal migration) only modulates secondary error margins and cannot override the first-order hard survival limits applied to sustained glacial-period trans-desert traversal. This manuscript is not presented as a definitive, all-encompassing synthesis of Pleistocene human evolution. Instead, it delivers a modular mechanistic scaffold designed to structure targeted fieldwork, quantitative global comparison, and genetic paleoclimate calibration for future empirical validation or rejection. Abstract The molecular clock has long served as the primary quantitative evidence for the Recent African Origin (RAO) hypothesis. Yet its outputs—no matter how mathematically elegant—carry no intrinsic constraints from hydrology, physiology, or oceanography. This manuscript reframes the research output as a testable competing evolutionary hypothesis, termed Limiting Stress-Driven Evolution (LSED), rather than an exclusive definitive conclusion. We demonstrate that the Sinai terrestrial corridor and Red Sea maritime passage cannot sustain late Pleistocene hominin dispersal under glacial or interglacial climatic constraints. Thermodynamic and chemical physiological thresholds impose non-negotiable survival limits on human migration routes. When molecular divergence dates are substituted into late Pleistocene arid zone hydrological boundary conditions, the mathematical timeline collapses. Physical natural laws remain invariant regardless of genetic modeling results. Calibration across multidisciplinary constraints indicates that northern mid-latitude seasonal stress zones, specifically the Yellow River Basin anchored by the Liaokao(聊考) Fault Zone, constitute the most consistent evolutionary forge for fully modern human adaptive suites.
