Re: Feduccia on MANIAC
John said something to the extent that Feduccia now believes basal
dromaeosaurids are birds, but remain unrelated to more derived members.
Although it
looks like he was careful in how he phrased it, this doesn't seem to be the
case.
>From Feduccia (2002):
If, as proposed by Paul (2002) and Czerkas et 2002), dromaeosaurs are
actually birds, either flightless or becoming flightless, then the question
bird
origins is again completely reopened. But aside from the obvious problems, that
proposal has major
implications because both camps in the debatewould have portrayed
dromaeosaurs incorrectly, and Czerkas et al. (2002:120) note, ââcladistics
has presented
a highly misleading interpretation of the evidence,ââ and (p. 122)
ââThe
origin of birds stems further back to a common ancestor of pre-theropod
status.ââ If correct, whatever the case, the presence Cryptovolans as a
dromaeosaur
with fully developed flight feathers, an avian style hand and sternum,
dromaeosaur teeth, sickle claw, and a stiffened dromaeosaur (rhamphorhyncoid)
tail,
should send those involved in the debate on bird origins back the drawing board.
PS: By the way, what was the earliest MANIAC paper? Maybe Olshevsky's strange
version of it?
