Doctor Who - Evolving into the Time War Daleks

Since the debut appearance of the modern Daleks in 2005, I've often wondered which Daleks did they originate from.

The originals created by Davros in 1975's 'Genesis of the Daleks' ?.

Or the Necros Daleks from 1985's Revelation of the Daleks' which evolved into Davros's loyal Dalek army, the Imperial Daleks of 1988's 'Remembrance of the Daleks' ?.

But on a hunch, I'd say the Time War Daleks originate from the originals, because for example in 'The Stolen Earth / Journey's End', it's quite clear that Davros was not in charge of the Daleks in that story, but a red and gold Supreme Dalek.

And all thou Davros is said to have had a Dalek command ship during the very first year of the Time War, it has been said that the true leader of the Daleks during the war was in fact the Emperor Dalek.

So this is just some idea of how the Dalek casing of Davros's original Daleks might have evolved into the Time War versions we see today in the series, evolving from what was the Renegade Daleks of 'Remembrance of the Daleks' into the modern versions. I've also often wondered how the Daleks might have evolved over time in the series had the series continued during the whole 1990's.

Guess not long after the events of 'Remembrance of the Daleks', the Imperial Daleks was completely eradicated in the years perhaps leading up to the Time War.

We don't even know for sure if Davros helped in the design of the Time War Daleks, only that he ended up with a chair perhaps based in them as seen in series 4 and 9.

Be great if someone could write a good enough story to talk about the evoltion of the original Daleks into their new series style.
