  abstract =     "We describe recent insights into the role of implicit
                 context within the representations of evolving
                 artefacts and specifically within the program
                 representation used by enzyme genetic programming.
                 Implicit context occurs within self-organising systems
                 where a component's connectivity is both determined
                 implicitly by its own definition and is specified in
                 terms of the behavioural context of other components.
                 This paper argues that implicit context is an important
                 source of evolvability and presents experimental
                 evidence that supports this assertion. In particular,
                 it introduces the notion of variation filtering,
                 suggesting that the use of implicit context within
                 representations leads to meaningful variation filtering
                 whereby inappropriate change is ignored and meaningful
                 change is encouraged during evolution.",
