History Main / TransplantedHumans

* ''Literature/LakeOfTheSun'' by Wynne N. Whiteford imagines that the Martians living in caverns deep underneath Mars (where there is sufficient air pressure to breathe) are actually humans who came from Earth in some long-forgotten past time (one strain of Martians have adapted to the dim light by developing a single, giant eye but are otherwise human. They see in 3D due to having two focus points in their single eye)

* In Creator/IanDouglas's ''Literature/SemperMars'', an expedition at Cydonia, Mars, discovers ruins half a million years old. An American archaeologist then discovers skeletons that appear to indicate that whoever had built the ruins also abducted ''Homo erectus'' from Earth and genetically modified them, possibly using them as labor to build the Face. An unexplained disaster then caused the deaths of both the Builders and the transplanted hominids.

* ''Webcomic/GrrlPower'': Due to centuries of [[AlienAbduction aliens abducting small numbers of pre-industrial humans]], there are a few million humans living among the wider galactic community. Cora mentions that most of the abductions were probably voluntary, though of course she can't be sure.

* The ComicBook/PostCrisis Franchise/DCUniverse used this trope to justify the HumanAlien [[PlanetOfHats Planets of Hats]] most of the ComicBook/LegionOfSuperHeroes came from: after the ''[[Comicbook/InvasionDCComics Invasion!]]'' CrisisCrossover event, [[strike:Mon-El]] Valor seeded several worlds with humans who had gained powers from alien experimentation.

* In ''Radio/TheHitchHikersGuideToTheGalaxy'', the humans currently on earth were descended from telephone sanitary workers and hairdressers, set to crash into the Earth by the other people on their planet, who were later wiped out by a disease that occured due to contaminated telephones.

* ''WebComic/TheCyantianChronicles'' takes place around the time period when Cyantia culture re-integrates with Earth. Most of the humans from Cyantia are descendants of alien abductees who were enlisted to help a precursor race with a biological problem, and chose to stay away from roman-age human civilization.

* In ''Franchise/StarTrek'':
** In ''Series/StarTrekTheOriginalSeries'', the ForgotTheCall episode "The Paradise Syndrome" featured a group of Native Americans transplanted to another star system by {{Precursors}} as a sort of cultural preserve.
** And Gary Seven's ancestors were taken from Earth to live on another planet, raising the perfect infiltration agents.

*** The episode [[spoiler:"Terra Nova"]] reveals that the race with whom Archer and his crew are making first contact are [[spoiler:the descendants of an early Earth expedition that lost contact with the home planet.]]
*** And yet another has them finding an Old West-style planet which was populated by abducted humans previously used as slave labor by the aliens who now work as ''their'' slaves.

* ''Series/{{Farscape}}'' This is where [[spoiler: Sebaceans, and probably Interions, come from.]] It's revealed in the "Peacekeeper Wars" miniseries that [[spoiler:the Eidolons, seeking a species no one had a grudge against to serve as the policing arm of their peacemaking efforts, took primitive humans roughly 27,000 years ago and genetically modified them. By the time of the series, they have a considerable interstellar empire, as well as many unaffiliated colonies.]]
* ''Series/BattlestarGalactica2003'' and ''Series/BattlestarGalactica1978'' both had this: "[[ArcWords There are those who believe that life here began out there]]." Kind of. In both versions, it was humans leaving Kobol of their own accord to settle the Thirteen Colonies of Kobol. This has been offered by fans as an alternative explanation to [[spoiler:identical evolution of humans on Kobol and Earth 2]] in the re-imagined continuity, however.

* In an episode of ''Series/{{Sliders}}'' an Alternate!Quinn's first test of the sliding machine (on a much larger scale) resulted in that Earth's entire population being transported to another world. As such, that other world now has double the population, although many duplicates try to stick together. Luckily, Prime!Quinn helps send them all back.

* In ''Webcomic/AmongTheChosen'' a race of aliens called "the Overseers" abducted a bunch of humans some time in the stone age as cheap labor. Thousands of years later some of those humans developed resistance to their mind control and built a device to destroy all the Overseers, it worked. The universe is now filled with [[{{Transhuman}} metahumans]] but earth is in a NoWarpingZone so most of them don't even know where it is.

* In Creator/LarryNiven's ''Literature/KnownSpace'' universe all the primates on Earth, including humans, are descended from a race called the Pak that were stranded on Earth a few million years ago. The reason humans are related to other life on Earth is that the Pak terraformed earth and wiped out most of the native ecosystem doing so. Similar colonization attempts resulted in the Morlocks of Wunderland (semi-sapient, cave-dwelling predatory hominids) and the various hominid species of the Ringworld. Furthermore, nearly all carbon-based life in the galaxy is descended from food yeast seeded on developing worlds two billion years ago by the first few alien races.

* ''Literature/SpaceAcademyDropouts'': One of the major advantages humans have is the fact that it turns out many colonies of these exist that include whole worlds of populations taken from Medieval and other times. This allows humanity to deal with other branches of itself even if they are rarely inclined to consider Earth to be anything special in dealings.

* Similar to the above, ''Literature/TheLostRegiment'' focuses on a group of Union soldiers being transported by a Tunnel of Light to another planet just after the Battle of Gettysburg. There, they find various cultures transplanted from Earth at different times, including Medieval Russians, Ancient Romans, Carthaginians, Ancient Chinese, etc. All of them are stuck in MedievalStasis, enforced by this world's true masters, a race of 9-foot-tall HumanAliens, who ride around the planet as [[TheHorde Hordes]] at different latitudes and collect tribute from their human subjects in the form of supplies and "[[IAmAHumanitarian cattle]]". It doesn't take long for the Americans to come into conflict with the Tugars, one of the alien hordes. Fortunately, the nearby human peoples are sick and tired of having to sacrifice some of their own to the Tugars every generation and would rather go down swinging. The Americans end up helping the locals industrialize and train in modern (by Civil War standards) combat.

* The Lor Republic, a star-spanning civilisation in ''TabletopGame/FreedomCity'', are descended from humans taken from Earth by [[PrecursorRace the Preservers]] tens of thousands of years ago. They ''utterly refuse'' to believe this, suspecting Earth might be a LostColony of Lor.

This trope is often combined with AncientAstronauts and/or AdvancedAncientHumans. Compare and contrast TranshumanAliens, where the descendants of the Transplanted Earthlings aren't human anymore, and {{Ultraterrestrials}}, where they never were. Compare LostColony, where the humans moved themselves. HumanityCameFromSpace is another possible explanation for humans on other planets.

'''Col. Kennedy:''' Teal'c, beings of this form evolved ''here'', on Earth.\\

->'''Teal'c:''' There is a tale of a primitive world the Goa'uld discovered millennia ago. The Tau'ri. The first world where forms of this type evolved. It is said the Goa'uld harvested among the primitives: some became Goa'uld hosts, others became Jaffa; the rest were taken as slaves and seeded among the stars to serve them. But that world has been lost for centuries.\\

* ''Literature/WildCards'': It is a matter of debate as to whether the Takisians were taken from Earth by the Network, or if Earth is a lost Takisian colony. Either way, they are biologically identical to humans, or were prior to the {{Eugenics}} program which developed the psychic powers and longevity of the Mind Lords.

* In ''DragonBallAfterTheEnd'', humans have somehow ended up across the galaxy. No one seems to be quite sure how, though.

* ''[[Literature/HumanxCommonwealth Midworld]]'' is home to a race of humans that descended from a failed colony but have been living in the [[SingleBiomePlanet world-wide jungle]] long enough that they've evolved to be shorter than average humans, [[YouGottaHaveBlueHair have green hair]] for improved camouflage, and have long prehensile toes for gripping branches. They've also evolved a psychic plant-empathy ability they call emfolling and have a symbiotic link with a six-legged bear-like species called furcots. [[spoiler:In fact, the entire planet is [[GeniusLoci sentient]] and chose to adopt the humans into it by giving them furcots, which are actually self-aware, mobile plants. Each human has a single furcot bonded to it, and when either one dies, the other quickly follows]].

* ''Anime/RinneNoLagrange'''s aliens are all humans who [[spoiler:left Earth after a great disaster 20,000 years ago]]. Madoka expresses a bit of disappointment at finding that out, noting it's like they are just coming home.

* ''Franchise/{{Halo}}'': The expanded universe explains that as humanity colonized the stars, they would occasionally find remnants of an ancient civilization on multiple worlds whose architecture was almost exactly like their own. It was revealed in the Literature/TheForerunnerSaga that humanity once had an [[AdvancedAncientHumans Ancient Interstellar Empire]] equally as powerful and advanced as the Forerunners. In fact, the Ancient Humans were the first to uncover the Flood by accident and the first to fight against them. Unfortunately, this caused a war with the Forerunners when the humans began cleansing worlds infected by the Flood, forcing them to fight a war on two fronts when the Forerunners declared war not knowing of the danger or even the existance of the Flood. Despite managing to drive back the Flood, the humans were eventually defeated by the Forerunners and as punishment were stripped of all their technology, devolved to a primitive state, and banished back to their homeworld, Erde-Tyrene aka Earth, where they were forced to start anew.

* ''TabletopGame/{{Banestorm}}'': The premise of the game is that the main setting, Yrth, was originally home only to elves, dwarves, gnomes, orcs, and ogres. A faction of elves attempted to rid themselves of the orcs by means of a grand spell, which backfired spectacularly and caused a magical catastrophe -- the titular Banestorm -- that transported enormous numbers of humans to Yrth from medieval Earth, establishing humanity as a significant presence in the world. This also applies to several other species that the Banestorm brought to Yrth besides the humans, including [[OurGoblinsAreDifferent goblins, hobgoblins]], kobolds and [[LizardFolk reptile men]] from a desert world called Gabrook, [[OurMermaidsAreDifferent merfolk]] and {{shark m|an}}en from the ocean planet Olokun, and [[OurCentaursAreDifferent centaurs]], [[OurGiantsAreBigger giants]], {{halfling}}s and [[ALoadOfBull minotaurs]] from the verdant world of Loren'dil.

* ''Franchise/{{Halo}}'': Some prerelease ''VideoGame/HaloCombatEvolved'' fluff mentioned that during the United Nations' colonization of stars near Sol, they occasionally discovered societies of primitive humans on worlds they knew for a fact no ships had been to; this was quickly made non-canon. However, actual canon media later revisited the theme by giving us Transplanted Human '''Architecture''' in ''Literature/HaloEvolutions'' and ''Anime/HaloLegends'', with ''Literature/HaloCryptum'' and ''VideoGame/{{Halo 4}}'' revealing that it's a result of [[spoiler:AdvancedAncientHumans: Humanity had a prehistoric spacefaring empire that seemingly beat back the Flood, then tangled with the Forerunners and had their asses handed to them]].
