IC & the Cambrian Explosion for Ahmad...cont..

Say, if he sees it like that (polyphyletic origin of phyla / one phylum equals one created kind, one 'creative act'), then I would expect Ahmad having no problems about evolution within each phylum. Sure, the ancestor of vertebrates did appear fully-formed one fine Cambrian evening by a miraculous act of creation; during the next 500 million years, they gave rise to bony fish, amphibians, dinosaurs, australopiths, and us through conventinal macroevolutionary processes.Hey, come to think of it, I don't have a problem with that kind of creationism...

What about the four-winged Microraptor gui? Maybe you can use it as an example of a 'wider' genome in the past?

Didn't he told you? One MPG=one phylum. However, he keeps humans and chimps separate.

FYI I agree with Feduccia also. The dromaeosaurs which dinosaur experts claim to be bird ancestors are committed runners. And IMO top-down flight evolution is more plausible than bottom-up. Take a look at Microraptor gui, this fossil showed a stage before Archaeopteryx. I agree with Feduccia, Chatterjee, and Mayr. And Darwin's original proposal of flight evolution is top-down (in bats, analogous to squirrels).

Dr Borger, did all whales come from one MPG (Ambulocetus?) or should they be split into three MPGs (archaeocetes(paraphyletic), toothed whales(paraphyletic), baleen whales (monophyletic)) or four (archaeocetes, baleen whales, sperm whales, dolphins (including orca)) or five (archaeocetes, baleen whales, sperm whales, dolphins, orca) or one MPG=one genus, or one MPG=one species like Homo vs Pan?[This message has been edited by Andya Primanda, 02-08-2003]

Please elaborate my predictions.

Since we're into whale MPGs let me throw in two other examplesDorudon atrox & Rodhocetus balochistanensisThat is the page of Philip Gingerich. He has some free PDFs at the bottom of the page.My prediction based on GUTOB: Rodhocetus was near the original Cetacea MPG, but it still has hind legs. Later processes eliminate the leg.Why do I start to think that the legs were created just to be eliminated later?
