This study pulls together fossil data and biogeochemical data to argue that the Cambrian explosion was really just a continuation of successive radiations that began in the Ediacaran and persisted to the Ordovician. A lot of bilaterian crown groups show up in the Cambrian, as did a lot of organisms making mineralized body parts, but there was plenty of origination of clades before the Cambrian began.

In the kingdom of the blind, better take public transit. Well, in the kingdom of the sighted, too, really--almost everyone is a terrible driver.
