Kagu close relationship between the kagu and sunbittern. The kagu and sunbittern, and possibly the adzebills, seem to form a distinct Gondwanan lineage of birds, possibly one order, possibly more, though the relationships between them and groups previously considered related, such as the mesites and the "core Gruiformes," are not yet resolved. It is notable, however, that the sunbittern and the mesites possess powder down too, whereas the "core Gruiformes" do not. While the kagu is the only living species in the clade Rhynochetidae, a larger species, the lowland kagu ("Rhynochetos orarius"), has been described from Holocene subfossil remains. The measurements
3D Virtual Creature Evolution (from zero, as not having an influence on fitness, to one, or having maximum influence) to determine the fitness goal. What generations the fitness function applies to can also be set. The environment, or “Terrain”, is then determined. This includes a flat plain, bumpy terrain (in which a hill is generated around creature that constantly inclines as distance is traveled from the creature’s spawning point), water (a low gravity simulator, non-functional), and “spheres” (spheres are generated above creature to catch). Everything in the simulation is viewed from a first person viewpoint. After settings are determined, the first generation is generated
