more birdlike feathers such as those seen in the earlier Archaeopteryx.>>
this is not, from my point of view,a solution; it's only moving the problem on the tree.
If they don't accept the evolutionary model proposed , then it doesn't matter what animal you're looking at.
If a hollow cilinder doesn't make sense to them(not to me) in Sinornithosaurus, then it won't make sense in any other animal either( if it's imilar to Sinornithosaurus, and Archie surely is, and I think Archie ancestors were too).
George, what do you think Archaeopteryx's ancestor's protofeathers looked like?
Sorry if I've made a question you've already answered to, but I can't go to the archives now(only e-mail download..argh) because of some connection troubles.
