Dalek of human origin
"Daleks of human origin" was a broad term that encompassed a range of different creatures related to the Daleks. Three main types of creature fell under the umbrella term:
- Daleks who remained in their casings and therefore weren't visually different from so-called "pure" Daleks of Kaled origin
- Hybrids who appeared neither Dalek nor human, like Dalek Sec in his final form
- Creatures who appeared fully human, but had some form of grafted Dalek genetic material
Nature
The ancestral Kaleds were indistinguishable from humans, yet the possibility of mutation into the creatures occupying Dalek casings was apparently integral to their DNA. It is therefore not entirely surprising that humans on occasion displayed the potential to mutate into creatures indistinguishable from mutant Kaleds.
However, the Daleks created from human genetic material by the Dalek Emperor had the xenophobic psychosis characteristic of Daleks who felt they had become "contaminated" by other races. The Ninth Doctor surmised that their inability to accept their fundamentally non-Dalek nature had driven them insane, thus accounting for their religious zealotry (something not seen in other Daleks). (TV: The Parting of the Ways)
Most other Daleks of human origin did not display this psychosis, although as the majority of them were created by Davros, it is probable he was able to eliminate this flaw in the nature of his creations.
The "original" Daleks considered the Daleks of human origin not to be "true" Daleks or thought of them as "contaminated". The first encounter between Daleks and human origin Daleks (possibly chronologically, not including time travelled events) was on the planet Necros.
The original plan was to recondition Davros' new Daleks to obey the will of the Supreme Dalek. It is possible, though, that the Daleks did not know of the new Daleks being created from humans. (TV: Revelation of the Daleks)
History
While in hiding from the Daleks on Necros, Davros created the first of what would later become known as the Imperial Daleks using the cryogenically frozen bodies of humans interred at Tranquil Repose. This process appeared to involve decapitating the subject and placing the surgically-modified head in a special Dalek casing. Mental conditioning was also obviously involved. All of the formerly-human Imperial Daleks were destroyed, either by the Dalek taskforce sent to extract Davros, or by the bomb detonated by the mercenary Orcini shortly after his departure. (TV: Revelation of the Daleks) Davros created Daleks out of mutated humans for his later invasion of Earth. (AUDIO: Terror Firma)
Mutant Daleks were clone versions of the real Daleks. Martez, in Asha's body, created them and ordered the Mutants to destroy the Eighth Doctor. Tricked by a hologram, he locked them inside the lab. The Daleks destroyed the doors and went out into the streets where they encountered two of the Dalek Supreme's Daleks. They tried to reason with them that they were all Daleks, but the Dalek drones refused to accept that, they explained that they deflected an asteroid to destroy the planet and opened fired. One was exterminated and three Daleks began shooting each other. One Dalek was killed, and one was damaged.
One Mutant Dalek escaped, bleeding, with severe damage. Back at the lab, it asked Martez why they attacked them and when he answered the question, the Mutant Dalek began to think like a real Dalek, and before it could finish its sentence, it died. The Dalek Supreme and the Daleks prepared to use their own ship to destroy the base. The Supreme Dalek and the rest took to the skies and "Dalek Fred" was left behind. The ship lost control by an explosion and crashed off-course. The Mutant base was still intact. Dalek Supreme decided to attack the hybrids head on.
When the Daleks descended from the red sky, the two Dalek groups confronted each other just outside the laboratory. The invading Daleks ordered the mutant versions to stand aside and allow them access, but their demands were refused. More of the new generation already outnumbered the original group, but the Dalek Supreme was determined not to let the fake creatures win. Refusing to self destruct themselves, they believed to be superior to the real Daleks and soon took their stand. A full-scale Dalek battle was about to begin, with both Dalek groups determined to completely wipe out the other, but then they heard the sound of a large group of humans advancing on their position. The humans attacked both Dalek groups, the Skaro Daleks and Martez's Daleks.
One of Martez's Daleks told him that the humans were attacked by them and they believed to be their enemies too. Refusing to listen to Martez, it told him to continue with the birthing. The Doctor confronted Martez about the Daleks fighting each other and forced him to stop, but he refused. The Doctor left, and after hearing his words, Martez shut down the power. The Mutant Dalek ordered Martez to reconnect or they would be defeated, but when he refused, he was exterminated. The Doctor, Lucie and Tom defeated both Dalek groups and the ones flying fell from the sky. The only Daleks left were the Supreme and one of Martez's Daleks. The last of his creations was killed and Lucie Miller saw what was inside it. Then, finally, the gold and crimson Dalek Supreme itself, bleeding and damaged, died. (AUDIO: Blood of the Daleks)
Daleks trapped in a time loop of their own creation, needing a pilot with an understanding of temporal theory, injected Mariah Learman with mutagenic drugs and exposed her to high levels of radiation before using a time corridor to massively accelerate the process of her mutation. The resulting creature was inserted into a Dalek casing where it served (briefly) as the required pilot, although this only compounded the loop rather than allowing them to escape. (AUDIO: The Time of the Daleks)
During the Last Great Time War, the Daleks gathered up humans and placed them in Glass Dalek casings which acted as incubators while the human inside was mutated into a Dalek, after which they would be placed into a standard Dalek casing. These Daleks were viewed as expendable and as cannon fodder due to their "impure" origins. The War Doctor and Cinder found five of these casings in a Dalek laboratory in one of their saucers at a temporary Dalek base in the city of Andor on Moldox. Cinder tore up the cables, allowing the people inside the casings to die in peace. (PROSE: Engines of War)
After the Alaska crashed into the Dalek Asylum, the imprisoned Daleks fully converted the ship's Junior Entertainment Manager Oswin Oswald into a Dalek, recognising that her intelligence could be useful to them. Oswin apparently retained her human emotions and personality, and, horrified at what had happened to her, placed her mind in a dream world where she believed she was still human and was safely holed up in the Alaska. A year later, Oswin lowered the Asylum's forcefield, allowing the Parliament of the Daleks to destroy it, stubbornly stating "I am Oswin Oswald, I fought the Daleks and I AM human". (TV: Asylum of the Daleks)
In desperate times, when their numbers needed to be significantly bolstered, groups of Daleks attempted to mass-convert humans into Daleks. (COMIC: *Sub Zero, AUDIO: Dalek Empire III, PROSE: Engines of War, TV: The Parting of the Ways) In the first two cases, this involved the direct transformation of living humans - bodies first, then their minds.
In the third case, following the Last Great Time War, the Dalek Emperor rebuilt the Dalek race out of harvested human DNA. This took centuries to achieve as so few human cells met the required genetic criteria. However, a force of half a million Dalek drones was eventually created. This army was obliterated by the Bad Wolf entity as it attacked Earth in 200,100. (TV: The Parting of the Ways)
A disturbing account discovered by the Doctor related the story of how Halldon scientists transplanted primitive humans to the planet Ameron and artificially accelerated their evolution. Creatures identical to the Daleks were the result of the experiment. (PROSE: We are the Daleks!)
