Remember "secondarily flightless" doesn't equate to "closer to birds than
Archaeopteryx", so no change in current phylogeny is needed to make
oviraptorids secondarily flightless.
Hows this for speculation. Maybe some theropods weren't secondarily
flightless from the bird line, but were secondarily flightless from a
theropods that could fly? What if Rahonavis isn't a bird, but a flying
dromaeosaurid? Which would mean flight evolved several times.
