Re: Campbell's even crazier than a MANIAC?
We can ignore, for example, that in *Caudipteryx zhaoianus* the manus is
even more avian-like than that of say, *Archaeopteryx* in that the third
digit is so highly reduced it has lost the distal phalanx and ungual,
resulting in a marvelous 2-3-2-0-0 (or 0-2-3-2-0) formula that exists
otherwise only in the ornithurine radiation.
(And in *Sapeornis*.)
Note that Hinchliffe's abstract in the same volume (I've not read the
paper) has a special reference to the fact that he dismisses, seemingly
out of hand, the frame-shift hypothesis, or even where the frame-shift is
supposed to have occured.
Well, I do think that hypothesis is wrong or at least unnecessary, but
that's because of the prepollex, something I bet Hinchliffe doesn't
mention... I'll read his paper sometime, though.
