Howling:Genesis of the Daleks already an alternate timeline?

I used to think that Dalek history didn't diverge from how it had previously gone until the exact moment the Time Lords sent the Fourth Doctor, Sarah Jane and Harry to ancient Skaro. But is it at all possible that history had already been rewritten when they arrived? One thing that suggests to me that this could be the case is the fact that in "Genesis", the Daleks are considerably more advanced than those in "The Daleks" and "The Dalek Invasion of Earth", being able to freely move outside without a need for static electricity. Could some unknown party have travelled back into Skaro's past and given Davros some helpful hints? If we want to get really wild, perhaps in the original timeline, Davros didn't create the Daleks at all, and they weren't designed until much later, after the remnants of the Kaleds had retreated inside the city in "The Daleks." (Incidentally, I have a theory that what the Thals say in "The Daleks" about the city being that of the Dals is true; the Dals were a third group that lived on Skaro at the time of the war, possibly allied in some way with the Kaleds, and after the Kaled city in "Genesis" was eventually destroyed/rendered uninhabitable, the surviving Kaleds went to live with the Dals in their city. The Dal cities' lack of a protective dome is a bit of an oddity, though, I do admit...) 82.2.136.93 08:38, August 2, 2011 (UTC)&nbsp
