The Parting of the Ways
In "The Parting of the Ways" (2005) the Emperor Dalek and the few surviving members of its crew hide in space for centuries after the Time War, harvesting organic material from captured humans and genetically manipulating it to rebuild their race. The Emperor tells the Doctor that a new Dalek army has been created using "filleted, pulped and sifted" human bodies, although they still consider themselves to be "...pure and blessed Dalek". When a Dalek is destroyed and the mutant revealed it is of a different appearance to the mutant seen in "Dalek", the prop hinting at a human heritage. Mutants originating from Kaled stock appear to have a closed, vestigial second eye, set below and to one side of the sighted eye. The mutant in "The Parting of the Ways" seems to have two identical symmetrically set eyes above which is a prominent supraorbital ridge. A large fleshy mass protrudes below the eyes, with folds suggestive of a mouth-like orifice.
