DAVID's comment: Of course adequate oxygen is a seeming requirement for the evolution of complex Cambrian animals. The authors' comments are a tautology which do not explain the sudden jump or gap demonstrated by the Cambrian Explosion itself.
-As I understand it, they are confirming the theory that an increase in oxygen triggered the Cambrian explosion. According to my hypothesis, this would have created conditions suitable for organisms to innovate. According to your hypothesis, God took advantage of the environmental change (or maybe initiated it - you never seem to be quite sure whether he controls the environment or not) to do lots of dabbles, or he had preprogrammed the first cells with all the innovations, and existing organisms then chose which programmes to switch on when the extra oxygen arrived.
