dc.description.abstract
Enigmatic rod-like skeletal structures that support compliant membranes (patagia) in aerial mammals have been often considered as neomorphic elements or as evolutionary novelties, and their origin has remained poorly understood. A potential source of skeletal plasticity and, probably, of morphofunctional innovations are sesamoids, which were recently demonstrated to have a common cellular origin with bone eminences. In this review, I compile information regarding anatomy, evolution, and development of rod-like skeletal elements in extant gliding and flying mammals and propose a working hypothesis on the origin of these structures. Rod-like skeletal elements, namely, the calcar in bats (Chiroptera), the unciform element in Anomaluridae (Rodentia), and the styliform cartilage in Pteromyini (Rodentia: Sciuridae), would derive from sesamoids, which, in turn, would have the same origin as eminences of long bones (or bones with a long-bone-like growth), i.e., calcaneus, ulna, and pisiform, respectively. Rod-like skeletal elements exhibit several features of sesamoids. However, further developmental data are needed to confirm this hypothesis, particularly whether these structures share a cellular origin and molecular developmental pathways with sesamoids and bone eminences. If this hypothesis were supported, a new role for sesamoids in generating morphofunctional innovations in mammals and, potentially, in other aerial amniotes, would be recognized. Rod-like skeletal elements, which are key in the evolution of aerial locomotion, might constitute an example of pre-existing traits that acquire novel functions through relatively little developmental plasticity.
