Homeorhesis, introduced by Waddington, describes the tendency of a developing system to follow inclination trajectories *despite* perturbations—this is the classic landscape/descent vision of developmental canalization. Allostasis emphasizes the **anticipatory** adaptation of regulatory systems to meet predicted demands. Both understandings of [[Telepoint]]s converge in their recognition that biological metastability is achieved through change rather than constancy, but they differ in their temporal scope: homeorhesis primarily concerns developmental trajectories and their robustness, while allostasis addresses dynamic, moment-to-moment adaptations to environmental challenges. The general understanding of stress responses can be understood as operating within nested constraints: immediate allostatic adjustments are shaped by homeorhetic trajectories established during development.
