Finger development disproves birds descended from dinosaurs (Talk.Origins)

Claim CB731:

Most scientists believe that birds descended from theropod dinosaurs. But theropod dinosaurs have lost digits IV and V from a primitively five-fingered hand, leaving them with digits I, II, and III. Birds, on the other hand, have digits II, III, and IV, having lost digits I and V. It is almost impossible for the two groups to be closely related with such a significant anatomical difference.

CreationWiki response:

This is nothing short of an admission that the claim is 100% correct, Talk Origins just throws in a bit of baseless speculation to try to save the dino to bird theory from reality.
