And every time a species goes to extinction the former new but filled niches vanish. Sounds a bit like a Steady state of musical chairs. Unfortunately the word evolution supposes purpose or direction which it seems steadfast to keep hidden.

More generally, virtually every new persistent mechanism (e.g., species) will create new potential niches by the fact of its existence. This can be seen by considering energy flows. Every persistent mechanism requires a way to exploit energy resources in order to persist. No mechanism is 100% efficient. So every persistent mechanism leaves in its wake some unused energy--often in a form that didn't exist previously That unused energy is then a niche that some other mechanism can exploit. To take Stu's example, the unused energy is whatever it is that bacteria in fish bladder live on.

There is an example of what happens with unused energy on a very large scale, Namely Forest fires after years of suppression rage with unbelievable ferocity. In this case a failure on the biological level to recycle fast enough results in a physical process almost beyond the biological . In this case the biological system is almost punished or negatively rewarded … This is interesting when one considers how closely coupled the two systems become. Perhaps it is better to think in terms of a footrace of sorts. No goal other than to stay ahead of disaster like surfing.
