+AD4- I was seriously wondering whether anything more than an odd shaped beak
+AD4- supports Feduccia's assertion that parrots are actually descended from
+AD4- pigeons+ADs- the tooth billed pigeon to be precise. He doesn't explain the
+AD4- notion in either of his two books on bird evolution. If anything about
+AD4- wing anatomy or something was there, I didn't see it.


If it's like most of Feduccia's assertions, I wouldn't get my hopes up. +ADs--)

I allways thought Feduccia did the whole psittaciformes off rather fast and mentioned them only fleetingly..as if he has a dislike of psittaciforms :D What surprises me is that he didn't seem to know the first thing about research claiming parrots were not closely related to pigeons at all,wich wasn't a new thought at the time of 'The origin and evolution of birds'.
When you think about it such a relationship would in fact seem very unlikely for the start. Seeing that columbiformes consisted of Pteroclididae and Columbidae,with the first representing the more primitive group it would be very strange to relate such an order to another order on the basis of similiarity of it's more derived family to this other order.Doesn't this scream 'convergence'?
