Touched

The Touched were a race of humans from a world known as P3X-797. The species later became extinct after SG-1 cured those afflicted.

Biology
No different from humans on Earth, they were afflicted with a disease that was called the Touch. It was a parasitic virus that fed on histamines and messed the body's chemicals. Those affected would revert to an early hominid with a prominent brow ridge and would be overcome with primal emotions such as lust and rage.

Culture
The Touched lived on the Land of the Dark away from the Untouched who lived in the Land of the Light. The Touch lived a primitive animalistic lifestyle similar to early man or Neanderthals.
