Evolution Conditioned by Space-Phase (SP3): Field Mapping, Cambrian Timing, and Testable Implications

Evolutionary theory successfully explains biological change through variation, selection,and inheritance, yet leaves unresolved why complexity stabilizes in narrow corridors, whylong stasis dominates the fossil record, and why innovation occurs in punctuated bursts. Inthe SP3 framework, spacetime itself possesses saturation, memory, and relaxationproperties that condition physical processes over long durations. This paper proposes thatbiological evolution unfolds within a conditioned space-phase, where stable spacetimetrajectories favor coherence across generations while saturated or rapidly varying regionssuppress complex organization. Without altering genetics or natural selection, SP3 providesa physical substrate beneath developmental constraint, punctuated equilibrium, andsensory convergence. A mapping to modified GR field terms is presented, Cambrian-scaletiming is interpreted as a global relaxation event, and testable implications are outlined.
