Bioengineering, or genetic engineering, was the science of altering the genes of a species to produce a desired result. The Nu-Cosian race was created through bioengineering, using genetic material from the Cosian species. Some geneticists surmised that the group of related species collectively known as the Delphidians were bioengineered as slaves by some long-gone master. Agricultural scientists Leo Leonis and his wife Tephra worked on creating genetically-modified crops to help feed the people of Chrona.
