There is an emerging theory on the evolution of complex stable systems.
(See for example Ilya Prigogine's book, _Order out of Chaos_.)

The mathematical theory of fixed points, and the related system-theoretic
idea of eigenfunctions and eigenvalues suggest that stable, recurring
modes or patterns may emerge naturally from any system when "the outputs
are shorted to the inputs".

Consider for instance, the map whose name is "The Laws of Physics and
Chemistry".  Plug in some atoms and molecules into this map (or
processor) and you get out atoms and molecules.  By the Fixed Point
Theorem, one would expect there to  exist a family of atoms and
molecules which remain untransformed by this map.  And this family
could have arbitrarily complex members.  DNA comes to mind.  (Crystals
are another example of a self-replicating, self-healing structure).

So the "random exceptions to entropy" may not be entirely random.
They may be the eigenvalues and eigenfunctions of the system.  The
Mandelbrot Set has shown us how exquisitely beautiful and complex
structures can arise out of simple recursion and feedback loops.
