  abstract =     "The generation of complex entities with advantageous
                 behaviours beyond our manual design capability requires
                 long-term incremental evolution with continuing
                 emergence. In this paper, we argue that artificial
                 selection models, such as traditional genetic
                 algorithms, are fundamentally inadequate for this goal.
                 Existing natural selection systems are evaluated,
                 revealing both significant achievements and pitfalls.
                 Thus, some requirements for the perpetuation of
                 evolutionary emergence are established. An (artificial)
                 environment containing simple virtual autonomous
                 organisms with neural controllers has been created to
                 satisfy these requirements and to aid in the
                 development of an accompanying theory of evolutionary
                 emergence. Resulting behaviours are reported alongside
                 their neural correlates. In a particular example, the
                 collective behaviour of one species provides a
                 selective force which is overcome by another species,
                 demonstrating the incremental evolutionary emergence of
                 advantageous behaviours via naturally arising
                 coevolution. While the results fall short of the
                 ultimate goal, experience with the system has provided
                 some useful lessons for the perpetuation of emergence
                 towards increasingly complex advantageous behaviours.",
