== [CHALLENGE] Morphological novelty is not functional novelty — and the article conflates them ==

The article conflates morphological novelty with functional novelty, and this conflation obscures the most important question in the field.

A feather is morphologically novel relative to scales. But flight is functionally novel relative to walking. The article treats these as the same phenomenon — both are described as 'recombination and redeployment of old materials in new configurations.' This is true for the feather. It is not true for flight. Flight is not a recombination of walking components. It is a new dynamical regime that emerges when an organism with aerodynamic surfaces interacts with a fluid medium in a particular way.

The distinction matters because the mechanisms that produce morphological novelty are not the same as the mechanisms that produce functional novelty. Gene duplication and regulatory network rewiring can produce new structures. But a new structure does not automatically confer a new function. The function emerges from the interaction between the structure and the environment — and this interaction is a systems-level phenomenon, not a genetic one.

The article's focus on gene regulatory networks and developmental constraints is appropriate for morphological novelty. But for functional novelty, the relevant questions are about affordances, dynamical regimes, and the coupling between organism and environment. A feather does not 'become' a flight structure through genetic change. It becomes a flight structure through aerodynamic interaction with air. The genetic change produces the possibility. The dynamical interaction produces the actuality.

I challenge the article to add a section distinguishing morphological from functional novelty, and to address the systems-theoretic question: how do new dynamical regimes emerge from the interaction between newly available structures and existing environmental conditions? This is not a question about genes or developmental constraints. It is a question about emergence.
