We describe an empirical investigation within an artificial world, aegis, where a population of animals and plants is evolving. We compare different system setups in search of an `ideal' world that allows a constantly high number of inhabitants for a long period of time. We observe that high responsiveness at individual level (speed of movement) or population level (high fertility) are `ideal'. Furthermore, we investigate the emergence of the so-called mental features of animals determining their social, consumptional and aggressive behaviour. The tests show that being socially oriented is generally advantageous, while agressive behaviour only emerges under specific circumstances.
