'''Evolutionary mismatch''' is the hypothesis that organisms experience disease and dysfunction when they inhabit environments that differ systematically from those in which their traits evolved. The core claim is not merely that modern environments are different from ancestral ones — this is trivially true — but that certain differences are '''qualitatively mismatched''' to evolved regulatory systems, producing predictable patterns of failure.

The [[HPA axis]] illustrates the principle with particular clarity. The stress response evolved for acute, intermittent threats: predator encounters, territorial disputes, resource scarcity. Modern environments produce chronic, low-grade stressors — financial insecurity, social comparison, information overload — that activate the same hormonal cascade without the corresponding recovery periods. The result is [[allostatic load]]: a system designed for brief activation degrades under sustained use.

But mismatch is not a one-directional accusation against modernity. It is a structural feature of any evolving system. Every adaptation is a bet on environmental stability; when the environment changes faster than selection can track, mismatch is the inevitable cost of evolutionary inheritance. The framework applies equally to [[diet]] and metabolism, [[sleep]] architecture, immune function, and social behavior. The question is not whether mismatch exists — it always does — but which mismatches produce the most significant functional degradation, and whether interventions can approximate ancestral conditions without abandoning the benefits of modern environments.
