Evolution, Part 1

Evolution is the eleventh episode of the seventh season of Stargate SG-1.

Plot
On an unnamed planet, Teal'c and Bra'tac visit a place where many dead Jaffa lie. They find a dead Goa'uld named Tilgath who wanted to forge an alliance with Ramius, whom they think betrayed Tilgath. They find Ramius' First Prime who tells them that they were attacked by a warrior, who then appears and kills the First Prime. Teal'c and Bra'tac fire on him with their staff weapons, but to no avail. The warrior then attacks with some sort of energy weapon on his arm but is finally killed by Teal'c with a zat. The warrior is then brought to Stargate Command where the two Jaffa inform SG-1 and Gen. Hammond.

Together with Jacob Carter, Maj. Carter examines the warrior, and together they discover that he is a genetic creation, brought to life by a Goa'uld symbiote. They also find out that the warrior died because of a heart attack and not because of the zat. Later it is discovered the warrior was apparently not alive when he was created and Selmak tells them how the sarcophagus was created by a Goa'uld named Telchak (who used a device of the Ancients) since he thinks the warrior was created by the same technology used to create the sarcophagi. Daniel remembers some research his grandfather Nicholas Ballard did about the Fountain of Youth and they surmise Anubis created the warriors by recreating the device using knowledge he obtained while ascended. Gen. Hammond then gives Daniel permission to search for Telchak's Ancient device. So Daniel travels with Dr. Lee to Honduras, where, according to Ballard's researches, Telchak's temple should lie. They are accompanied by a guide.

At the SGC, the others plan to capture one of the "super soldiers" alive by stunning him with a small dart that should penetrate his armor. SG-1, some SG teams, and several Rebel Jaffa go to Ramius' planet since they think that a warrior will appear there. When the warrior arrives, he withstands all their weapons, kills some Jaffa, and finally escapes, while the others are captured by Ramius' Jaffa and imprisoned. They are confronted by the Goa'uld, but he doesn't believe their story about the warrior. They then discuss what to do about the warrior when suddenly they hear the warrior attack and the guarding Jaffa run to their master. It turns out that he was killed and so the Jaffa let the prisoners go. SG-1 is then able to capture the warrior with a Tel'tak.

In Honduras the three go into the jungle in search of the temple and finally find a hidden entrance to it, which Daniel and Lee enter. At a dead end they find the Ancient healing device but when they remove it from its location they activate a trap and the temple is flooded. The two barely make it to the entrance, but when they leave the temple they are confronted by guerrillas, who capture them and shoot the guide when he tries to flee. At the guerrilla camp, Dr. Jackson and Dr. Lee are interrogated but refuse to talk. The guerrilla leader Raphael then threatens them with torture and death.

At SGC attempts are made to interrogate the prisoner, but he reveals only that he serves Anubis. However, thanks to a Tok'ra memory device it is discovered that the warrior was created on a planet named Tartarus. Suddenly, General Hammond enters the room and explains that Dr. Jackson and Dr. Lee were kidnapped and may have crossed the border into Nicaragua, much to the shock of the others.
