Dysvolution
Dysvolution, in the covolution framework, is the general viability-eroding counterpart of covolution, at any scale: change in which system–symvironment coupling and functional-information processing degrade, so that the system's accessible trajectories become less stable, less adaptive, or less open-ended. It is not "evolution backward"; it is impaired covolutionary coupling. Where covolution expands viable organism–symvironment trajectories, dysvolution collapses or misdirects them. The term combines Greek dys- ("faulty, ill") with -volution.
Relation to aging
Dysvolution is the genus; gerorhesis is its species in the aging domain — dysvolution as it occurs in an individual horon over its lifetime. Antonym pairs: covolution ↔ dysvolution (general); gerostasis ↔ gerorhesis (aging).
Relation to capacity C
In terms of functional-information-processing capacity C = (A, M, P, K), dysvolution is degradation of the viability-weighted ‖C‖ (Δ‖C‖ < 0), whereas covolution is its increase or better organization and gerostasis its maintenance.
