Hominid Cognitive Ignition

This doctrine entry captures the archive's narrowest defensible version of the cognitive-ignition hypothesis. It does not claim that Thermosynapsida exposure alone produced symbolic thought, language, or human modernity. It claims instead that prolonged residence near signal-active geothermal caves supplied a persistent selective and perceptual environment: one that rewarded low-frequency sensitivity, spatial memory, and the ability to encode danger and return across generations. In archive usage, the hypothesis is contributory and environmental, not mystical.

Claims

c0001 - Repeated exposure to signal-active cave systems favors low-frequency sensitivity and predictive cave knowledge

The archive proposes that hominin groups repeatedly using geothermal caves would have benefited from detecting subtle acoustic, seismic, or geometric precursors of an approaching phase shift at depth. Over long spans, any standing variation that improved low-frequency sensitivity, spatial memory, or anomaly discrimination would become fitness-relevant in a way it was not in ordinary surface environments.

c0002 - HLSF-like exposure environments recruit the same perceptual systems later central to symbolic elaboration

The doctrine links recursive field exposure to bilateral symmetry detection, default-mode activation, and persistent entity imagery. In archive reasoning, these are not hallucinations floating free of context but structured responses to patterned environments. Communities that encountered such environments repeatedly would be more likely to preserve form, recurrence, and direction in durable symbolic media.

c0003 - Early serpent and dragon imagery is read as memory technology before it is read as theology

The archive treats recurrent serpentine imagery as a practical encoding system before treating it as mythic decoration. In this reading, the image stores a bundle of linked facts: underground depth, return after absence, danger at thresholds, and the need for collective memory longer than any single lifespan. Symbol comes first as retention, only later as cosmology.

c0004 - The cognitive-ignition model is additive, not exclusive

The archive does not displace demographic, linguistic, dietary, or social explanations for the human cognitive transition. Its claim is that cave-signal environments supplied one more selective context among several. The doctrine's force lies in specificity: a known class of environments, a proposed perceptual pathway, and a resulting archive of symbol forms that persists across cultures.

c0005 - The move from cave encounter to settled ritual is a transfer of encoded knowledge into portable forms

As communities shift from deep-cave residence toward more mobile and eventually settled lifeways, the archive expects knowledge to migrate from place-fixed practice into objects, gestures, stories, and built spaces. This is why the doctrine treats later ritual architecture and dragon myth as continuations of Paleolithic signal management rather than as a wholly separate civilizational invention.
