Human Humans were a species of sentient primate s . ( COMIC : " The Monster Upstairs " ) Though humans could trace their evolution ary past to Earth , ( AUDIO : " Bloodtide " ) many billions of humans were born on other worlds after humanity spread through the cosmos . ( TV : " New Earth " ) Humans became so widespread that they eventually came to emphasise their relationship to worlds other than Earth , choosing to think of themselves not as Earthlings , but as Venusian s and Martian s . ( PROSE : " The Dalek Book " ) Their genetics gradually altered as they " mingled " with other species . ( TV : " The End of the World " ) Earthbound or Earth - identifying humans went by many names over Earth ' s long history . For a time , they were commonly called Tellurian s or Terrans — both derived from alternate names for Earth . ( TV : " Carnival of Monsters " , " The Two Doctors " ) Earthling was also sometimes used , such as by . ( TV : " The Sound of Drums " ) Ape , a reference to humans ' evolutionary cousins , was a pejorative alternative particularly favoured by Silurian s ( TV : " The Hungry Earth " , " Deep Breath " ) and , especially in his ninth incarnation , the Doctor himself . ( TV : " Rose " , " Father ' s Day " ) Later in their evolution , humans became known as posthuman s . ( PROSE : " The Book of the War " ) Nevertheless , the Doctor had a special affinity for the species , claiming at least once to be part human himself , ( TV : " Doctor Who " , COMIC : " The Forgotten " ) and stated himself to be human on occasion . ( PROSE : " Doctor Who and the Daleks " , TV : " The Unwilling Warriors " ) He also did twice " become " fully human . ( PROSE : " Human Nature " , TV : " Human Nature " ) The overwhelming number of his travelling companion s were human . He also admitted in a Gallifrey an high court that he had a special affinity for Earth and its inhabitants , thereby determining the location of his Time Lord - imposed exile .

( TV : " The Ark in Space " ) The inhabitants of Mondas , Earth ' s twin planet , who were very close to the Terran humans genetically , also called themselves " human " . ( TV : " World Enough and Time " ) However , to differentiate them from Earth ' s humans , they were usually referred to as " Mondasian s " . ( COMIC : " The Flood " ) Characteristics . Traits and abilities . Humans were special in the universe . Humanity had an instinctive need to protect their own genetic line . This could make some individuals resistant to control , such as cyber - conversion . ( TV : " Closing Time " ) Like other creatures , humans generated pheromone s , chemicals that used scent to subconsciously affect the responses of others . Enhanced pheromones , both natural and artificial , were capable of altering sexual behaviour in humans . These pheromones could be packaged in spray bottles or emitted by a body , such as the gaseous creature who possessed Carys Fletcher . ( TV : " Everything Changes " , TV : " Day One " ) Innate psychic abilities were rare but not unheard of . Some humans had telepathic powers , though in almost all cases it was weak or suppressed . ( PROSE : " The Left - Handed Hummingbird " ) Individual humans displayed psychic powers such as psychometry , telepathy , empathy , or time - sensitivity . ( TV : " Planet of the Spiders " , " Image of the Fendahl " , " The Unquiet Dead " , " Human Nature " , " Hide " ) Humans had little in the way of telepathic emissions , and were difficult to track telepathically . ( PROSE : " Blood Heat " ) Unusual traits of humanity . The human brain was the only source of a chemical that allowed restfullness .

( TV : " The Coach with the Dragon Tattoo " ) The Twelfth Doctor claimed humans were the only species in the universe who used Emoji . ( TV : " Smile " ) Perceptions by other species . Other species ascribed a variety of traits to humans . Dalek Sec of the Cult of Skaro , after physically merging with the human Mr Diagoras , noted that the human emotions he felt included ambition , hatred , aggression and " a genius for war " ; he considered the species " so very Dalek " at heart . Sec also described humans as " the ultimate survivors " , and Dalek Caan cited the fact that versions of New York City would continue to exist throughout history , as opposed to the Dalek race , which was nearly wiped out . ( TV : " Daleks in Manhattan " ) Some aliens were dismissive of humans ; the Rutans considered them " primitive bipeds of no value " . ( TV : " Horror of Fang Rock " ) Others saw them as a potential threat or , in the case of the Shakri , as " pests " that deserved to be wiped out . ( TV : " The Power of Three " ) The Mantasphid s , who referred to humans as " fleshy bipeds " and fought a war with them on Myarr , considered them dangerous but also amusingly stupid .

( TV : " Doctor Who " ) The Tenth Doctor perceived the species to be one in its infancy , with great potential , ( TV : " The Christmas Invasion " ) and remarked he viewed them as " giants " when Wilfred Mott incorrectly believed the Doctor , as a Time Lord , must view them as mere " insects " .

( TV : " The Christmas Invasion " ) The Eleventh Doctor criticised humans ' ability to be tricked into having " every inch of Earth ' s existence " profiled by the Shakri cube s because of them being the " great early adopters " of the cubes , letting the cubes into their homes and work .

This was later undone by the Time Lord Rassilon . ( TV : " The End of Time " ) In 2011 , on Miracle Day , death ended for every human simultaneously when the Three Families filled the Blessing with the immortal blood of Jack Harkness , which altered humanity ' s morphic field and forced every human to continue living regardless of any injuries or illnesses .

( PROSE : " The Brakespeare Voyage " ) By the year 5 , 000 , 000 , 000 , interbreeding and evolution had resulted in there being only one " pure " human left , Cassandra O ' Brien . Δ17 . Cassandra no longer had a recognisable human form however , due to the life - extending surgeries she had undergone . Although believed killed soon after the destruction of the Earth , ( TV : " The End of the World " ) she survived , only to die several decades later after a failed attempt at transferring her consciousness to Rose Tyler . ( TV : " New Earth " ) Despite O ' Brien being described as the last human ( TV : " The End of the World " ) , the human race in some form continued . At some point in their history , the humans spent millions of years as gas . They also spent time as downloads before re - evolving into humanoid form .

At this time , humans on the planet Malcassairo were hunted by a race of humanoid s called the Futurekind . Some believed that the Futurekind were what humans would later become , while others dismissed this idea .

When asked , he identified as not originating from Earth , but did not deny his humanity in other senses . ( TV : " The Time Warrior " ) Indeed , the term " human " was often loosely applied to non - human species that were humanoid or even simply sentient . According to Mesanth , " human " could refer to any human - like creature , so a more precise term like Earthon should have been used to refer to the Earth ' s inhabitants . ( PROSE : " Shining Darkness " ) The First Doctor used the term , including himself a Time Lord , the Dalek s and the Thal s , to contrast with plants .

( TV : " The Evil of the Daleks " ) The Third Doctor , shortly before regenerating into his fourth incarnation , suspected that the one who stole a deadly disintegrator gun was " more than human " . After the defeat of the perpetrator , a robot named K1 , Sarah Jane Smith reflected on how human it had seemed at the start . The Fourth Doctor agreed , saying it was " a wonderful creature , capable of great good , and great evil " — which was what he saw humanity to mean . ( TV : " Robot " ) " Human " was also a measure of morality ; " inhuman " was frequently used to scold immoral people . ( TV : " The Evil of the Daleks " , " The Seeds of Doom " , " Planet of the Spiders " ) In fact , even the Doctor had been shown to use " inhuman " as a synonym for " monstrous " on multiple occasions .

But the Daleks didn ' t . " ( TV : " The Ambush " ) The Sixth Doctor once claimed that Robert Knox ' " distinct lack of humanity " was what gave him away as a human , rather than an alien force .
