The new evidence is very ambiguous and totally inconclusive. No far-reaching conclusions should be drawn from such dubious material.
None of the Cambrian animal phyla is represented in the Ediacaran fossil record.
The fossil record speaks clearly and cries out loud: the history of life on Earth is a history of saltations.
It is remarkable, indeed, how detailed a medusoid morphology was projected onto Kimberella fossils and later recognized as pure fantasy.
If identified as an animal, it would “predate the Cambrian explosion of bilaterian animal phyla as a kind of ‘advance guard.’”
