Genetic and organisational explanations need not compete for a single explanatory role. They may address different questions about the same biological phenomenon, and their explanatory contributions must be assessed relative to the explanandum.
Genetic explanation may identify how genetic variation is generated, inherited, expressed, regulated, and associated with biological differences. Depending on the question, such explanations may be sufficient without requiring an additional organisational account.
Organisational explanation asks how components, activities, constraints, and relations contribute to the organisation of a living system. Within APS, this includes asking how they participate in viability-oriented, constraint-closed organisation and its maintenance through change.
The presence of an organisational context does not by itself establish that an organisational explanation adds explanatory value. Nor does identifying a genetic mechanism establish that every organisational question has thereby been answered.
The relevant comparison is therefore:
- What is the explanandum?
- What does the established genetic or mechanistic explanation already explain?
- What additional relations, if any, does organisational analysis make explicit?
- Does making those relations explicit contribute explanatory integration, or merely redescribe what is already adequately represented?
APS treats Agency, Process, and Scale as complementary analytic projections of one living organisation, not as additional causal components or levels acting alongside genetic mechanisms.
Key Point. APS does not claim explanatory priority over genetic explanation. Its organisational contribution must be demonstrated relative to the explanatory question and to what the strongest established explanation already provides.
