Accident (a dicto secundum quid)

Biological Parallel

Applying general rules to exceptional cases: 'Predation regulates prey populations' is generally true, but fails when prey have refugia (cliffs, burrows, dense vegetation where predators can't access). The accident fallacy ignores special circumstances that invalidate general principles. Island species without predators lose anti-predator behaviors (flightless birds, naive seals). Context overrides general rules. Biological principles are domain-specific, not universal.
