Systems found near attractors have very limited adaptability (a single value gives little room manoeuvre). In nature such systems tend to fall out of harmony with their environment and die out.

\Vho would have thought a few years ago that the central planning that was one of the cornerstones of communism would be so completely discredited and
that we would see such widespread faith in the 'hidden hand' of market f'orces. This failure, though, is an inevitable consequence of the emerging theories of chaos and complexity.
Chaos Theory - tells us that behind apparent disorder (a swirling stream) there are in fhct discernible patterns and relationships between events. These patterns allow us to determine hounds of behaviour but the detail is sometimes chaotic. \Vhen talking about non linear system (cg ones with feedback loops - most of the real world) it is often impossible to predict future

this in nature as cells organise themselves into plants and these into forests and so on. Furthermore quite simple behaviours in the original entities can produce quite complex metabehaviours. A computer simulation was created of flying birds each with the following simple rules:
