This is interesting.

I was getting a at balance of complexity with respect to the energy cline.
Its possible there is a natural ratio and we humans have moved it off balance.
Of course if we took our hands off, the balance would re-emerge - but it would take millions of years(how many millions is debatable.)

Of course there is a question of how the complexity is weighted and what effect the largest fauna should have on it. But big animals do seem to always occur naturally.

Sounds a lot like the work that Kauffman was doing... "The origins of Order" etc. However last time I looked this field was still in its infancy.
