Winged flight as an innovation ecosystem. This table shows multiple (non-exhaustive) biological levels of organization, how they are associated with invention, novelty and innovation, and how these associations manifest in the example of winged flight in birds, which originated in dinosaurs and persists to this day in their avian descendants with numerous adaptive and novel modifications [68,69], and loss of flight in certain lineages. ‘Winged flight’ is a convenient label for an innovation, but the underlying adaptations and novelties form a trait complex, and together with environmental interactions, compose an innovation ecosystem. All components of this innovation ecosystem (e.g. developmental pathways, tissue architectures, and behaviours) contribute to winged flight, and generic examples given (e.g. in the ‘molecules, cells, tissues’ level) are non-exhaustive. Components may themselves be novelties or innovations, may be singular to wings and flight, and may have been co-opted or modified from other trait complexes (see e.g. [70] for the origins of feathers). Symbol x (?) indicates that the entity does (may) affect the associated biological level.
