Four to 12 pups are born in late summer and early fall, measuring . Bonnetheads have one of the shortest gestation periods among sharks, lasting only 4.5–5.0 months. A bonnethead female produced a pup by parthenogenesis. The birth took place at the Henry Doorly Zoo in Nebraska; DNA analysis showed a perfect match between mother and pup. The bonnethead is an abundant species and is currently classified as a least-concern species by the IUCN. It is heavily
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
