193 (Footnote) I was a biological engineer working with a large staff of technicians. It was our business to manufacture and supply new lifeforms to uninhabited planets. There were millions of star systems with millions of inhabitable planets in the region at that time. There were many other biological laboratory companies at that time also. Each of them specialized in producing different kinds of lifeforms, depending on the "class" of the planet being populated. Over along span of time these laboratories developed avast catalogue of species throughout the galaxies. The majority of basic genetic material is common to all species of life.
