(3) The "stability flapping" behavior suggested as part of RPR is
consistent with a "flapping-first" hypothesis of the origin of avian
flight. But isn't this at odds with Senter's (2006) work which
inferred that flapping came late to birds, because the scapular
orientation in non-ornithoracean paravians precluded a full stroke?
That would seem to be the case.
It is an elegant and clever idea, nonetheless.
