The Primal Wars were a series of conflicts of which humans were presumably a part. They took place during the Tenth Segment of Time and it was during these wars that all knowledge of the common cold virus was lost. (TV: The Ark)
Behind the scenes[]
The Discontinuity Guide suggested that, if the Segments of Time corresponded to a variable length of time, the Primal Wars could be the same as the war between the Galactic Federation and Galaxy Five. However, if the segments were of roughly equal length, it is stated that the Primal Wars would have taken place nearly two million years into the future.[1]
