Kaled Kaleds were one of two humanoid races which originally inhabited the planet Skaro . They were the ancestors of the Dalek race . Biology . The Kaleds could be distinguished from Thal s by their dark hair and eye s . ( TV : " Genesis of the Daleks " ) Internally , Kaleds also differed from both human s and Thals . Blood tests showed that humans and Gallifreyan s were biologically very dissimilar to them . ( TV : " Genesis of the Daleks " ) Kaleds had purple tissue and their ribs were more widely spaced than those of humans . ( TV : " The Stolen Earth " ) They had thicker lung s than the Thals and they had a copper - based blood with a green tint . The Kaled heart was grey . ( AUDIO : " Corruption " ) Towards the end of the Thousand Year War , the life expectancy of Kaled females had declined to 52 , an age which Davros ' mother Lady Calcula had long since surpassed by the time of her death . According to Davros , she was one of the oldest living Kaleds . ( AUDIO : " Corruption " ) By that time , few Kaleds had died of old age in ten generations . ( AUDIO : " Davros " , " Corruption " ) Culture . During the Thousand Year War , the Kaleds lived under a totalitarian government in which the military was very powerful , although unlike their descendants they understood and approved of the concept of democracy ( TV : " Genesis of the Daleks " ) They were led by the Supremo . ( AUDIO : " Purity " ) Beneath him were the Scientific Elite and the Military Elite , who lived in special bunkers . The majority of the population lived in the Kaled Dome , most of the other cities having long been destroyed . Kaleds mutated by radiation and chemicals , the Mutos , were exiled into the wastelands . ( TV : " Genesis of the Daleks " ) , they were joined by deserters from the military , who also succumbed to the toxic conditions and mutated . When Davros and his team fled a Thal factory , they were attacked by Mutos from the wastelands . ( AUDIO : " Purity " ) All young Kaleds were expected to serve in the Military Youth . According to Lady Calcula This provides the young with " skills and opportunities to progress . . . should they live long enough to take advantage of them " . When Davros was 16 , he was still considered to be a boy , while 18 year old Yarvell was regarded as " almost a woman , no longer a child . " Yarvell herself considered this " trapped in the middle of nowhere . " ( AUDIO : " Innocence " ) As time passed and the war grew more intense , while joining the Military Youth was still technically voluntary , societal attitudes had made joining compulsory to the point where children were beaten or even killed for failing to join or questioning the war effort . At this time , there is no clear lower age limit on joining , as children as young as 8 had joined ( AUDIO : " Corruption " ) The Kaleds believed that in all the " seven galaxies " they were able to study only Skaro was capable of supporting intelligent life . They were consequently surprised to find that the Doctor and his companions were not from Skaro . ( TV : " Genesis of the Daleks " ) The Kaled god of war was a " horned beast " which was thought to have been inspired by the Beast . ( TV : " The Satan Pit " ) " Captain Croag and the Highland Rangers " was a popular children ' s programme on Kaled television . Calcula also mentioned that they showed children footage of battles in classrooms to persuade children to join the military , although she considered the edited highlights " too sanitised " . ( AUDIO : " Corruption " ) In the final days of the Thousand Year War art was still being produced , but the artists were shunned by the majority in the Kaled Dome . ( AUDIO : " The Lights of Skaro " ) History . Origin . The Kaleds externally resembled Thals , but their last common ancestor had diverged some 100 million years previously , this was very shortly after the development of multi - cellular life on Skaro . ( AUDIO : " Corruption " ) However , one account states that both the Kaleds and the Thals were descended from humans transplanted from Earth to Skaro as an experiment by the Halldon s . ( PROSE : " We are the Daleks ! " ) Prior to or during the Thousand Year War , the Kaleds mastered alchemy . ( AUDIO : " The Lights of Skaro " ) Thousand Year War . Originally , the Kaleds and the Thals lived together in peace , archaeologists discovered the ruins of ancient cities containing artwork depicting Kaleds and Thals even intermarrying on occasion , though this research was suppressed by the Kaled government for political reasons . ( AUDIO : " Purity " ) Due to unknown circumstances , the Kaleds and Thals engaged in the Thousand Year War . Both sides originally used advanced energy weapons , but the materials and industrial equipment required to make them became scarce . By the end of the conflict the majority of soldiers were armed with weapons similar to those on early 20th century Earth such as bolt action rifles , submachine guns or even bows . At this point only two cities on Skaro remained intact , these domed cities overlooked a polluted wasteland brimming with sand and radiation as well as booby trap s such as handmine s and conventional landmines . ( TV : " Genesis of the Daleks " , " The Magician ' s Apprentice " / " The Witch ' s Familiar " ) Near the end of the war , Davros was studying the effects of radiation on Skaro ' s flora and fauna . He concluded that the Kaleds would have to mutate into a new form of life , the Daleks , to survive Skaro ' s decimated biosphere . In order to achieve this eventual outcome , he gave the means to destroy the Kaled city to the Thals to justify the creation of the first Dalek army , which he sent to destroy the Thals . Though some Kaleds objected , Davros ordered his Daleks to exterminate them . The Daleks subsequently rebelled against their creator and proceeded to exterminate his remaining followers and nearly the scientist himself , ironically while he screamed for them to show emotions he had conditioned them against . ( TV : " Genesis of the Daleks " ) Revival . During the Last Great Time War , Daleks found themselves evolving back into humanoids on the Neverwhen planet front as a result of time phasing . Perhaps inspired through observing this as suggested by Cardinal Ollistra , ( AUDIO : " The Neverwhen " ) a faction of Dalek Scientist s secretly plotted to restore Kaled mutants to their humanoid form on Asteroid Theta 12 , culminating in Project K006 .
