Isn't the base function of all limb forms retained, that being the locomotion of the organism, even though the morphology has undergone drastic alteration?

That's what I'm saying. At the morphological level, and therefore also at the genetic level, all that is happening at each stage is a modification of an existing structure. However, the cumulative effect of all this is a significant change in function (from swimming to crawling to walking to flying or to performing a Beethoven piano sonata). At no point is one of Behe's "FTC's" required. All that happens is the shape and proportions of the various individual bones are modified.
Pebble seems to think otherwise, however, if I understand him correctly.
