A lone Wraith Scientist conducted experiments to make feeding off Humans more efficient. Violating the wishes of the rest of the Wraith, he tried to make humans more compatible by adding Wraith DNA into their genetic makeup. However, his results found that humans gained the ability to access the Wraith psychic network telepathically. He tried to dillute the effect by returning some of his test subjects to interbreed with other humans, but any amount of DNA was able to give humans access. Worse, many of the subjects went mad and were ostricized from their village. Unable to get around the problem, the scientist gave up. The Wraith eventually learned of his experiments and wiped out the village, but the scientists fate is unknown. (ATL: "The Gift")
