Conserving Coherence Under Constraint

Louis T Joseph , Denise Joseph

Across biology, organisms facing energy shortage, time pressure, or threat narrow their range of activity: they lower metabolic demand, restrict behaviour to a few coordinated patterns, or move in close synchrony with their neighbours. These responses are strikingly similar across otherwise unrelated systems, yet they are studied in separate literatures, and their resemblance is usually attributed to convergent selection. Accounts of the convergence have been offered within particular lineages. What remains open is one that yields a common signature and a shared way to test it. We propose that these responses reflect a single principle, the conservation of coherence: when the demand to coordinate exceeds the capacity to do so, a biological system preserves coordinated function by shedding variables that were varying independently and reorganizing the coupling among those that remain, while defending the variables most critical to viability and retaining the machinery needed to re-expand. This transition should leave a common four-part signature wherever it occurs, and the claim is not that each element occurs, which is largely known, but that they occur together as one transition. From that principle we derive four testable hypotheses covering the joint signature itself, the threshold at which systems simplify, the asymmetry between entry and recovery, and the relation between simplification at one organizational level and coordination at another. Because coherence is inferred from convergent, system-specific measurements while the signature stays fixed, the principle applies from cells to social groups and is falsifiable in each, and existing continuous-monitoring datasets already permit direct tests. We build on a recent cross-taxonomic framework for animal dormancy, extending its scope beyond programmed dormancy to acute defensive states and collective behaviour, and identify where current evidence is strong and where it remains to be gathered.
