Trace Source Emergent Origin of Culture Theory (TSI-OCT): Function → Requisites → Deficit → Behavior → Culture

TSI-OCT proposes a trace-source, emergent evolutionary ontology with regards to cultural origins framed as a sequential function-to-requisites-to-deficit-to-behavior-to-culture progression. Once structure-and-function stabilizes, continuation becomes conditional on requisites; requisites imply the likelihood of shortfall; and shortfall, when present, is deficit. Deficit instantiates Need Functions (NF) as organized closure patterns that bias sensing, prioritization, coordination, and action toward restoring or advancing viable continuation within a declared boundary and horizon. Because closure is frequently complementary—distributed across internal and external co-mechanisms—effective closure often requires recruitment and coordinated participation at group scale. Communication is therefore treated as a downstream instrument of recruitment rather than an origin cause: internal states and reasons are conveyed outward into a shared field so coordinated closure becomes feasible. A single worked exemplar (hunger) traces the pathway from tissue shortfall to sensing, hunger, hunt/gather action, recruitment, and stabilized group procedure. Culture is defined as the transmissible procedure-memory of how a group repeatedly completes closure across time, carried in tools, roles, norms, routines, and institutions.
