Abstract
We simulate an individual-based model that represents both the phenotype
and genome of digital organisms with predator-prey interactions. We show
how open-ended growth of complexity arises from the invariance of
genetic evolution operators with respect to changes in the complexity, and that the dynamics which emerges shows scaling indicative of a
nonequilibrium critical point. The mechanism is analogous to the
development of the cascade in fluid turbulence.
