While this simulation is simple and agents are provided with a minimal number of input sensors and available actions, very interesting behaviors can result.
One interesting herbivore strategy entailed herding . An herbivore would follow another herbivore if it were in front. The analogy could be strength in numbers as long as you're not the herbivore in front. Carnivores found numerous interesting strategies one of which was finding plants and then waiting for herbivores to wander by. This strategy was successful but short-lived as herbivores finally evolved the ability to avoid carnivores, even if plants were in the vicinity.
