Memory is organized into informational patterns that exploit CPU time for self-replication.
The creative aspects of evolution have been more elusive to model. However, these parasites search for the missing information, and if they locate it in a nearby creature, parasitize the information from the neighboring genome, thereby effecting their own replication. In some runs, hosts evolve immunity to attack by parasites. In some runs where the community comes to be dominated by immune hosts, parasites evolve that are resistant to immunity. This drives the parasites to extinction.
