This also suggests that there is room for many more organisms
since the available resources will be more efficiently utilized
by the specialized ones (or that there will exist fewer but
One factor which is important when looking at this kind of
economized ecology is how complexity grows within an economy.
How does new economical niches develop, and how stable are they?

True. But there still seems to be a rather strong force towards
maximizing efficiency at the cost of everything else. But this
could just be the initial growth phase; in alife simulations
like Tierra we first see a fierce competition for maximizing
reproductory ability, and later the development of "ecological
niches" like parasites and hyperparasites. It seems likely that
it is this second order evolution that would produce an
interesting environment. Unfortunately it is not well understood
at present, since most alife simulations only seem to be able to
sustain fairly simple "ecosystems" (likely because of their
size). Maybe we need more interaction between colonies in the
commons scenario for the emergence of complexity.
(Maybe it would be worth adding even more Tierra-like
"programmability" to the civilisations of the simulation I'm
writing so that they could actually develop open-ended
strategies. Worth thinking about...)
