DAVID: You miss the point that a Cambrian rise in Oxygen does not require an advance in complexity. It only allows for it. Therefore some other force must exist requiring complexity to appear.

dhw: I didn’t think I would need to repeat it, but my hypothesis proposes that evolution advances not only through organisms’ requirements for the purpose of survival but also through their drive for improvement (not all, of course – just the bright, adventurous, inventive ones). I am suggesting that given new opportunities, such as a changed environment, some organisms use them to develop new ways of life, e.g. if Freddy Fish finds himself confronted by dry land, he might go exploring...do I need to go over this again?

Only if someone gave him a set of lungs in advance of his landward perambulation.
