History Main / TransplantedHumans

* S.M. Stirling's novels ''[[TheLordsOfCreation The Sky People]]'' and ''In The Courts of the Crimson Kings'' update the Burroughs depiction of Mars and Venus by being set in an alternate timeline in which aliens terraformed Mars and Venus millions of years ago and have since periodically transplanted species from Earth to the other planets.

* FrancisCarsac's ''Les Robinsons du Cosmos'' (''The Robinsons of the Cosmos'') involve an unexplained cosmic event (later theorized to be a "collision of universes") resulting in a chunk of the French countryside (a village, an observatory, a rocket factory, and a Swiss millionaire's castle) being transplanted to another world. The planet (which they call Tellus, Latin for "earth") is Earth-like but features some hostile life-forms that force humans to find a new place to settle. They meet an indigenous race of centaurs called Ssvis, who agree to let humans settle in their territory. The Frenchmen build a new settlement called Cobalt City and help the Ssvis fight their ancient enemies the Slvips (black centaurs). Also, after spotting a strange airplane, the Frenchmen discover that they weren't the only ones transported to this world. A chunk of the US (as well as Argentina and Norway) was also transplanted onto a sinking island. The residents of Cobalt City help rescue the sinking Americans, Argentinians, and Norwegians and let them settle nearby. As a result, the French end up nearly fighting the new American nation. In the end, all friendly nations form the Union of Tellus Republics with Cobalt City as the capital and spend the next several decades exploring the planet. Since the planet is implied to be in a different universe, it's highly unlikely that it will ever be rediscovered.
* The Martians in ''{{Spin}}'' are all descended from humans who were sent to the planet in hopes that the lack of Earth's time-dilation effect would cause their civilization to outpace Earth's, thus giving them some better idea about the nature of the Hypotheticals.

* The PostCrisis [[TheDCU DC Universe]] used this trope to justify the HumanAlien [[PlanetOfHats Planets of Hats]] most of the ComicBook/{{Legion Of Super-Heroes}} came from: after the ''ComicBook/{{Invasion}}'' CrisisCrossover, [[strike:Mon-El]] Valor seeded several worlds with humans who had gained powers from alien experimentation.

This is an increasingly common (and admittedly [[TropesAreNotBad pretty good]]) way to [[JustifiedTrope justify]] HumanAliens, by making alien humans.

* The ''Series/MysteryScienceTheater3000'' episode ''FutureWar'' featured a race of alien cyborgs who had visited Earth at some point in the past and kidnapped both humans ''and'' dinosaurs--the humans they used as slave labor and the [[strike:really cheesy forced-perspective puppet]] dinosaurs they used as "trackers". They failed everything forever.

* ''Series/BattlestarGalacticaReimagined'' and ''Series/BattlestarGalacticaClassic'' 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.

* ''LastExile'' : Though kind of a subversion, since humans transplanted ''themselves'' and two of the three nations became FantasyCounterpartCulture [[LostColony Lost Colonies]] at the mercy of the more advanced, CrystalSpiresAndTogas DeadlyDecadentCourt faction.

* Implied to be the case with the [[GreenSkinnedSpaceBabe Syreen]] in StarControl.

* UnicornJelly: The main explanation for humanity's appearance in a twisted universe: [[spoiler:4th-dimensional holes in space and time (a natural occurrence due to the multiverse's instability) cause random pockets of reality to transport instantly from one universe to another. Chou explains that it's like rain: when rain falls, it's round because of the properties of surface tension, and makes a circular shape when it hits a flat surface; the holes in time and space are similar, teleporting orbs of people into a new reality. The odds of this happening are astronomical, but in the Unicorn Jelly universe it happens. It's unknown how many have died compared to how many survived, but there are enough to start a utopian civilization]]. This later happens to a different alien species, complete with one person panicking (much like the old lady from the first batch of transplantees).

* ''The Algebraist'', by [[Creator/IainBanks Iain M. Banks]], has '[=aHumans=]' (the humans who were taken to join galactic civilisation in about 4000 BC) and '[=rHumans=]' (tho ones who made it out themselves seven thousand years later). There is some animosity between these groups. Slightly averted, though; these two groups make up only a small fraction of sentient beings even among the 'Quick' species (of which humanity is a member).

* In the ''GlobalGuardiansPBEMUniverse'', the alien Daribi invaded the earth four times (in 1898, 1938, 1953, and 2005). Each time they were beaten back. During the 1953 invasion, mankind finally captured several of the invaders, only to find out that they were the descendants of Neanderthals who had been transplanted to another planet 75,000 years earlier. They were rescued from extinction on Earth by SufficientlyAdvancedAliens and taken to a world that wasn't actively killing them off.

** 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.

* FracisCarsac's ''Les Robinsons du Cosmos'' (''The Robinsons of the Cosmos'') involve an unexplained cosmic event (later theorized to be a "collision of universes") resulting in a chunk of the French countryside (a village, an observatory, a rocket factory, and a Swiss millionaire's castle) being transplanted to another world.

* The Daribi, a race of alien invaders from the ''GlobalGuardiansPBEMUniverse'', are transplanted neanderthals. They were rescued from extinction on Earth by SufficientlyAdvancedAliens and taken to a world that wasn't actively killing them off.

* According to an offhand comment by Geromi in ''Crux'', this is why nearly all the worlds in CrossGen's SharedUniverse have [[HumanAliens humans of some kind]]. Even the high fantasy, low fantasy, feudal Asian-ish, and Victorian worlds, as well as the more science-fiction worlds. Ironically, "true" humans on Earth are all but extinct. [[spoiler: Because they artificially Transcended this universe and became the Negation.]]

* The {{Backstory}} for ''Franchise/StarCraft'' mentions that the first Terrans (humans) in the sector were exiled criminals transported off Earth as their punishment, a la Australia. In the ExpansionPack, ''Brood War'', those who stayed on Earth catch up with them. And while the Earth humans are absent in ''VideoGame/StarcraftII'', a good chunk of the tech that Rory Swann develops is reverse engineered from their tech. Since the [[OneWorldOrder UED]] Expedition force was wiped out by the Zerg with no survivors, those left on Earth have no idea what's going on in the Koprulu sector. Sending another fleet would probably not be their priority.

* The Saga of the Skolian Imperialate, by Creator/{{Catherine Asaro}}, posits a small group of Mayans who were kidnapped by an unknown species and transplanted to the planet Raylicon. The kidnappers left their starships behind. The Raylicans experiemented with the discarded technology, created an interstellar empire, fell, reachieved starflight, and then encountered humans from earth just as they invented stardrive theory from scratch.

* In [[DavidWeber David Weber's]] ''EmpireFromTheAshes'' trilogy, humans on Earth are transplants descended from the stranded crew of an interstellar warship which has disguised itself as the Moon. Humans were originally native to another planet, Mycos (as is all the other life on Earth - explaining why it is biologically related to humanity).

* In LarryNiven's ''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. Furthermore, nearly all carbon-based life in the galaxy is descended from food yeast seeded on developing worlds 2 billion years ago by the first few alien races.

* In WilliamShatner's ''QuestForTomorrow'' series, this is revealed to be the fate of the Neanderthals. A ship belonging to a LizardFolk race found Earth a long time ago and found two sentient species on the planet. The ''homo sapiens'' were dismissed as unimportant, while the Neanderthals turned out to be [[PsychicPowers telepathic]]. Desiring to learn the secret of telepathy, this particular faction transplants a good number of Neanderthals to a remote planet and then wipes out the rest with a virus, engineered specifically to kill them. After a series of failed experiments, the lizards decide to kill off all their subjects as well. They release the virus and leave. This time, however, some of the Neanderthals survive and build a civilization of their own, albeit much slower due to the lack of writing (telepaths don't need to write). Decades before the series initial timeline, the Neanderthals have only reached Industrial Revolution, while humans are already a star-faring race. They then AscendToAHigherPlaneOfExistence by turning their star into a black hole.
* TheAlgebraist, by IainMBanks, has 'aHumans' (the humans who were taken to join galactic civilisation in about 4000 BC) and 'rHumans' (tho ones who made it out themselves seven thousand years later). There is some animosity between these groups. Slightly averted, though; these two groups make up only a small fraction of sentient beings even among the 'Quick' species (of which humanity is a member).

* The ''SomethingWickedSaga'' by Music/IcedEarth is told from the point of view of the Setians, a race of ReptilianHumanoids who were indigenous to Earth and [[HumansAreBastards nearly got wiped out by invading humans]].

* Creator/CJCherryh's ''Literature/MorgaineCycle'' novels used a similar concept (complete with {{Cool Gate}}s) decades earlier.
