On the Origin of Cognition

This essay proposes a staged account of the evolutionary development of cognition, decoupled from strict phylogenetic timelines. Beginning with reflexive sensorimotor couplings and genetically encoded instincts, the essay traces the transition to experience-dependent learning, internal simulation, and generalisation. Intelligence is characterised as an adaptive strategy that enables organisms to occupy composite niches beyond the constraints of fixed physiology. Human cognition represents a qualitative shift driven by the crossing of an Individual Sufficiency Limit, promoting distributed specialisation, social coordination, and cumulative cultural transmission. In this view, the genome functions as a bounded rule set that delegates adaptive flexibility to learning systems — partially offloading its task of stabilising and propagating acquired solutions across generations to a cultural layer.
