-'''Homeorhesis''' (from Greek ''homoios'', "similar" + ''rhesis'', "flow") is the maintenance of a dynamical trajectory — a stable flow pattern — rather than a static equilibrium. The term was coined by [[Conrad Waddington]] to extend the concept of [[Homeostasis|homeostasis]] from states to processes. Where homeostasis returns a system to a set point, homeorhesis keeps a system on course: a developing embryo maintains its trajectory toward a particular morphology despite perturbation, not by returning to a previous state but by adjusting its ongoing development.
+'''Homeorhesis''' is the dynamic regulation of a developmental trajectory rather than the maintenance of a static equilibrium. Where [[homeostasis]] corrects deviations from a fixed setpoint, homeorhesis corrects deviations from a trajectory — it keeps a system moving toward a predetermined endpoint even when perturbed. The term was coined by developmental biologist Conrad Waddington in 1957 to describe how embryonic development proceeds along a stable path despite genetic and environmental variation. It has since been extended to any system that maintains a directional process rather than a stationary state.

Homeorhesis implies that biological stability is often stability of a process, not of a condition, and that the mathematical tools for analyzing it require [[Dynamical Systems|dynamical systems theory]] rather than control theory alone. What remains unclear is whether homeorhesis is a distinct biological principle or merely homeostasis applied to a moving target — and whether the distinction, if real, has empirical consequences for how we model [[Developmental Plasticity|developmental plasticity]].
+The concept is critical for understanding systems that are not merely self-regulating but self-directing. A homeostatic thermostat returns to 22°C. A homeorhetic embryo continues toward a mature form even when the sequence of intermediate states is disrupted. Homeostasis is about returning to where you were. Homeorhesis is about continuing to where you are going.
