Cylon History

Template:Cylons Series The humans of the Twelve Colonies reveled in their technology and used it not only for good, but for war between themselves. The Cylons, a group of machines designed for hard labor and warfare, were built. Over time, the humans specialized the design, giving the machines a form of artificial intelligence.

The Cylons rebelled against their masters, and the Cylon War began. Humans responded by building battlestars and fighter craft named Vipers to combat the Cylons.

The war lasted nearly 12 years, with the Colonies close to a fall. But an armistice was declared, and the Cylons departed the Colonial worlds in search of a home of their own.

While absent from human observation during the armistice, Cylons eventually evolved or created new models of Cylons that were organic in nature and essentially identical to humans. The evolution is most likely a result of learning capabilities incorporated into the early Cylons. With the exception of a glowing red spine, it is quite difficult to determine the difference between a humanoid Cylon and an actual human (Miniseries).

Another significant difference is the presence of silica pathways, a technology used in Cylon design, which are vulnerable to a specific type of radiation found at Ragnar Anchorage (Miniseries). Dr. Gaius Baltar is able to successfully build a Cylon detector based on the subtle differences between Cylon and human tissue with the help of his virtual Number Six. however, he has determined it is simpler for everyone "if all the results are green."

An interesting new step in the evolution came about with the conception of a Cylon-human hybrid, the child of Sharon Valerii and Lt. Karl Agathon.

Note

The show's creators expressed that the glowing red spine was, in retrospect, a continuity error that was visually appealing at the time, as viewers have rarely seen the glowing-spine effect in later shows since it was first introduced in the Miniseries.
