In the episode, Stargate Command and its allies encounter a new enemy "Super Soldier", who is impervious to their weapons. Believing that the Goa'uld Anubis has created this enemy using Ancient technology, Dr. Jackson (Michael Shanks) travels to South America to investigate a similar device mentioned in legend. Meanwhile, the rest of SG-1 along with their allies Bra'tac (Tony Amendola) and Jacob Carter (Carmen Argenziano) hatch a plan to capture one of the soldiers alive.

The writers wanted to introduce a new enemy in response to more and more of the Jaffa defecting and turning against the Goa'uld, as well as creating a soldier that was a much more powerful adversary. "Evolution" part 2 broke rating records for the Sci-Fi Channel as the channels most watch broadcast to-date, as well as being the most watch episode of Stargate SG-1.
