​Interlude: The Butterfly’s Color and the Limits of Adaptationism

Within the framework of the traditional Darwinian paradigm, the color of a butterfly’s wings is most often explained functionally: as a means of camouflage, mate attraction, or predator deterrence. In such accounts, a single difference—color—is rendered capable of performing various functions depending on context. But this points not to the universality of explanation, but to its post hoc adaptiveness: the explanation follows the difference, assigning it meaning retrospectively, according to how it appears within the environment.

Such an approach fails to distinguish the ontological status of the difference itself from the semantic level of function. Yet color, as a difference in the butterfly’s bodily form, precedes its designation as "useful" or "harmful." Within the ontology of differentiation, color is not a function, but a node of difference, emerging from Potentiality and retained in the body as form—at level R₂. It is not explained by an external goal but acts as an internal tension, entering into resonance with other differentiating nodes: predator, mate, light, vegetation, shadow.

Teleological explanations—such as “the color exists to attract” or “to repel”—are secondary. What is primary is that the difference is formed and retained in form; the question of what happens to it in the Game pertains not to function but to rhythm: in what field the difference participates, what relations it creates, with what it resonates.

In terms of the principles of the ontology of differentiation, this can be articulated as follows:

According to the First Law, the resonant transfer, if a difference cannot be retained locally—for instance, if it ceases to be attractive to mates due to shifting preferences—it may still be preserved in another resonant field: it may acquire a new function, such as deterrence, or become part of camouflage. In biological terms, this may correlate with genetic mutations or ecological changes, such as increased predation pressure or a shift in habitat.

The Second Law, the conservation of distinctness, adds that even if a specific meaning of the difference is nullified, the difference itself does not vanish. It continues to persist in form, though its significance in the Game may shift—transitioning from one resonant field to another.

This means that difference is primary, and function is a mere epiphenomenon. Every difference retained in form participates in the Game and may be woven into various rhythms—as signal, as noise, as mask—requiring no justification, only participation.

Thus, the ontology of differentiation does not reject evolution, but refuses to reduce it to optimization. Evolution is not a path toward best adaptation, but the movement of differences through forms in which Potentiality manifests.

Contemporary biology confirms that evolution is not always tied to adaptation. Neutral theory shows that many differences—such as coloration—may arise from random mutations, unrelated to selection. The notion of suboptimality emphasizes that traits are often far from ideal, shaped by historical constraints or side effects.

The butterfly’s color, in this view, is a form of the differentiating, participating in the Game—not a function to be explained. If we wish to understand why the butterfly is as it is, we should not ask why, but listen to how its difference sounds in the field of Potentiality.
