Eureka. It was the oxygenation from 2 billion yrs before that explains the sudden explosion of life forms.

It was one hell of an earth changing event both undersea environ & the atmosphere, we'll see just how in depth Meyers goes with tapping into stages leading up into the Cambrian. But the great oxygen event cannot be ignored & a theory thats really backed up by the data & would have great impact on what animals survive, which don't, opening up new niches and the distinct possibility for a period of rapidly changing forms filling those niches.

As for the book The Cambrian Explosion: The Construction of Animal Biodiversity by Douglas Erwin and James Valentine, lets hope your boy Meyers is as up to date on the fossil record, dating issues, evolutionary developmental biology, climate change, and the response of molecular phylogeny to it.

Meyers isn't breaking new ground here but they sure are playing up as if he has, which reminds me once again of what PT Barnum once said of people & the circus.
