dhw: Sorry, but these scientists claim that there were plenty of novel bodyplans during the transition period, and new discoveries are being made all the time. And the second article provides an example which closes the gap:

Heading: Paleontologists Find Evolutionary Link between Ediacaran and Early Cambrian Multicellular Animals

DAVID: Finding one link does not explain the vast array of new phyla appearing so suddenly. A small link is not a gap buster.

dhw: But an accumulation of links would gradually close the gap.

DAVID: Only if Edicaran precursors appear for 37 original phyla in the Cambrian.

dhw: Bearing in mind the extreme unlikelihood of ANY fossils surviving, I’d settle for just a few.

DAVID: I'm not surprised.

dhw: And I’m not surprised that you want every single species to have left a complete fossil record of its evolution throughout hundreds of millions of years. Nothing less would shift you from your fixed beliefs. But at present, I only ask for open-mindedness. The Cambrian is still an unsolved mystery!

DAVID: No it isn't. God designed it.

dhw: You love to present your unproven (and probably unprovable) theories as facts.

Faith has a role. Your faith is riveted to closing the gap that frightened Darwin.
