History[]
When discussing the possibility of who created the nanovius the Atlantis expedition encountered in Atlantis in 2005, Dr. Elizabeth Weir questioned if it had been the Wraith. Dr. Carson Beckett considered that was the possibility but Dr. Rodney McKay disagreed. He pointed out that humans are food to them. He used the example of it being the equivalent of cattle farmers making mad cow disease. (SGA: "Hot Zone")
