Physical Conditions for the Stability of Evolutionary Change

This paper examines evolution from a physical perspective, identifying the conditions that allow ordered biological systems to persist while undergoing incremental change. Building on Schrödinger’s analysis of hereditary stability, the work argues that evolutionary processes depend on three general physical features—coherence, continuity, and constraint. These features maintain ordered relational structure under perturbation, ensure uninterrupted generative activity, and limit viable directions of variation. The manuscript develops a conceptual model showing how evolutionary transitions can be understood as reorganizations of relational structure within a bounded stability domain. The approach offers an incremental, physics‑first clarification of the physical requirements underlying evolutionary change.
