I think you could "model" evolutions behaviour pretty well on the assumption
that it "aims" to fill all available eccological niches.
My reading on genetic algorithms shows me that evolution can be regarded as
an exteremly powerful general purpose problem solving technique. It may
well be that mental processes actually solve problems in the same way: by
selecting, combining and mutating ideas. To me evolution _is_ a thought
