The origin of this behavior is thought to be linked to the positive selection of DNA damage checkpoint and immune system genes according to Zhang et al.âs comparative study of M. davidii and P. alecto.

Garner et al.âs model for this behavior posits that the asymmetry between remiges and retrices evolved relatively late. Groups of organisms that engage in this behavior may coordinate with one another in a way described by the chorus-line hypothesis. In one group of organisms, thoracic displacement causes the âindirectâ form of this activity, in which the muscles responsible for this activity are attached to the tergum and the sternum. In some organisms, the supra-cora-coideus and its antagonist, the pectoralis, are actuated as part of this behavior. A precursor to this behavior is called âincline running,â and Rhamphorhyncus and Quetzalcoatlus are members of the first vertebrate clade to evolve this facility. For 10 points, name this mode of locomotion used by pterosaurs, which is unavailable to ostriches.
