I`ve read through (...again) Feduccias
counterarguement that the frame shift theory is just "accommodating the
cladogram", and am surprised to find that he dosen`t bring up the fact that
frameshift dosen`t seem to account for the anterior necrotic zone (the ANZ) that
Hinchliffe uses as an arguement for the existance of a digit that failed to
develop due to cell death in this anterior region.
(I find this necrotic zone intriguing, because
it might indicate a previously existing "pteroid bone" which would
reinforce my idea that the avian line actually split off from a pterosaurian
condition...By the way,...also thereby preserving the 1,2,3 digit identity!)
Aside from this Feduccia paper ("1,2,3=2,3,4: Accomodationg the
cladogram"), I haven`t heard any other counterarguement from the
"birds are not from dinos"camp on this issue. Of course, they weren`t
at the recent SVP gathering either.So,...what`s the status here? Ay new papers
in the works??? Have they capitulated? (I somehow doubt
it!).
