->'''Kyon:''' Do I have to live in this gray world all alone with ''her?''\\
'''Itsuki:''' Adam and Eve. If you reproduce enough, it'll work out?\\
'''Kyon:''' I'll smack you.
-->--''[[LightNovel/HaruhiSuzumiya The Melancholy Of Haruhi Suzumiya]]''

This is a plot where the remainders of a group, especially an entire race, must be protected from extinction. Occasionally, the final two actually do perish, but not before producing offspring who repopulate the species.

This, of course, [[HollywoodScience ignores real population genetics]], where a certain minimum number of ''genetically divergent'' (i.e. unrelated) individuals are needed in a gene pool to maintain a healthy genetic diversity over the generations. For humans it is an estimated 497 individuals (no joke) although 1,000+ is to be preferred. The general rule of thumb is the "50/500" guideline -- that a population founded by 50 genetically diverse humans in isolation would last about 2,000 years before inbreeding did them in, while 500 or more stand a chance of lasting indefinitely so long as all of them reproduce and no major disasters wipe out a significant part of the gene pool during that time (although as with everything else involving genetics, this is a gross oversimplification and varies greatly with the conditions encountered). You usually won't find this in [[BrotherSisterIncest direct siblings]]. More casually, this results in the unspoken implication that said newly propagated species does not have a problem with incest. [[ElephantInTheLivingRoom This rarely comes up.]]

In particularly {{anvilicious}} scenarios, the two survivors who rebirth their species will actually be [[AdamAndOrEve named "Adam" and "Eve"]], or some fairly obvious variations on those names. This is sometimes called a [[{{Pun}} Shaggy God Story]].

Literary note: the "Adam and Eve" plot is mentioned (in a bad way) in many articles and books on writing science fiction stories. Apparently it was, for many years, one the most over-used {{twist ending}}s in the badly written stories that make up the editors' [[SturgeonsLaw mountainous "slush pile" of wasted efforts]] - in fact, many editors would reject stories with this twist ''on sight''.

Usually found coupled with a NewEden; if some manner of vehicle or protective capsule is employed, this becomes [[TheArk an Ark]] or a CityInABottle. Often the end result of EarthAllAlong. May overlap with AncientAstronauts and/or lead to AdvancedAncientHumans. Related to LastOfHisKind. Sister trope of OnlyYouCanRepopulateMyRace. Not to be confused with CoitusEnsues.

[[folder:Anime and Manga]]
* In ''Anime/EurekaSeven'' movie ending, Renton and Eureka became that very symbolic couple after Earth was flooded. Eureka was reborn relying on Renton's survival, memories and dreams, in a way similar to Eve being born from Adam's ribs.
* In ''Anime/{{Megazone 23}}'' Part I, the character Eve is introduced as a mysterious idol and Megazone is revealed to be a CityInABottle. In Part 2, Eve explains that she has taken it upon herself to hand-pick a worthy remnant who will survive after the superweapon A.D.A.M. destroys the Megazone, and hopefully make it safely by ark to the regenerated Earth where they can begin repopulating it.
* Subverted in ''[[LightNovel/HaruhiSuzumiya The Melancholy of Haruhi Suzumiya]]'': After [[spoiler:Haruhi starts splitting off another dimension containing (at the moment) only Kyon and herself]], Itsuki [[spoiler:temporarily appears from the original world]] and jokes that Kyon and Haruhi could be the new Adam and Eve and populate the world. Kyon is not amused. They wouldn't have been alone for long, though.
* ''Anime/NeonGenesisEvangelion'': At the conclusion of the series [[spoiler:[[OfficialCouple Shinji and Asuka]] are left as the only two surviving humans on an utterly transformed and devastated Earth.]]
** Subverted, [[spoiler:as it's said during the [[AssimilationPlot Instrumentality]] that the rest of the humans may join Shinji and Asuka in the new world if they wish it in their hearts. [[Main/AmbiguousEnding We just never]] [[Main/BittersweetEnding see that happen.]]]]
* ''Anime/GallForce'': The ''Anime/GallForce: Eternal Story'' {{OVA}} focuses around a crew of a space ship consisting of a OneGenderRace named the [[HumanAliens Solonoids]] who are racing to claim a new homeworld and the Paranoids, an enemy alien race. One character is absorbed into an alien gelatinous mass and she ends up becoming pregnant via a FaceFullOfAlienWingwong. The cast surgically remove it, thinking it's an infection, and it rapidly grows into an OppositeSexClone. He and one girl end up being the last two survivors by the end, and go on to produce the entire human race.
* Subverted in the manga ''Manga/EdenItsAnEndlessWorld'', where, AfterTheEnd, two teenagers, Ennoia and Hana, think they're the last people alive. They've both been thinking about the inevitable ''a lot''. After a heartfelt discussion on the matter, they decide to stay in "our Eden", but Ennoia decides that they "don't have to live our lives according to mythology. And that means when we have kids, we don't have to name them 'Cain' or 'Abel', either." [[spoiler:As it turns out, they aren't the last people alive, but they might as well be; Most of the remaining population, which is already ridiculously minuscule, has TheVirus]].
* This makes up roughly the first third of the sixth volume of Osamu Tezuka's ''Manga/{{Phoenix}}'' manga, ''Nostalgia''. And while the genetic difficulties are addressed, eventually the problem is resolved when [[spoiler:the race of aliens capable of taking on any form send a representative on the behalf of the Phoenix. This crossbreeding creates a new species of half human, half moopie.]]
* Seen in the ''last page'' of the ''Manga/{{Narutaru}}'' manga, with [[spoiler:Shiina's daughter and Kuri's son, playing on the beach where the series started. It's unclear as to whether their mothers are still alive.]]
* In the manga ''Beautiful People'' by Mitsukazu Mihara, only two people seem to have survived in Japan (and maybe the world) because they accidentally trapped themselves in a bunker for one week while civilization ended. The bomb just killed living beings on the outside without damaging other objects, so they can loot canned food and survive easily for a while. Hopes for them to re-populate the world are... low, as one is a gay man and the other is a lesbian woman... oops.
* Completely averted in ''Manga/DragonBall'' where in ''Online'', you find out that the last survivors of the Saiyajin race, Vegeta and Goku, were unable to rebuild the Saiyajin life through interbreeding with humans. Saiyajin are now extinct.
** Played straight, though, in that somehow Fat Buu was able to produce an entire race of beings from just ''himself''. And seeing as he was a creature [[AWizardDidIt created out of pure magic]] in the first place, that doesn't seem very unlikely. He probably just [[StarfishCharacter split into multiple pieces]] and let them become separate beings instead of reforming. Specifically, he read one of Mr. Satan's adult books, and through it wanted to experience love. So he ended up creating his wife (the aptly named Booby), and then hit her with a ''love beam'', thus causing her to be impregnated with a child. And apparently over the span of a few centuries, this occurred so much it lead to the creation of an entire race. Majins must have a lot of free time on their hands.
* Inverted in ''Anime/SonicTheHedgehogTheMovie'', where Robotnik wants to ''cause'' the extinction of humanity, except for himself and Sara, so they can get married, have children, and live out their days on an empty planet. Sara responds by attacking Robotnik.
* Yuji and Marlene in ''Anime/BlueGender'' eventually find themselves in this role, even though they weren't the last remaining humans on Earth.

[[folder:Comic Books]]
* In a variation, on pre-ComicBook/{{Crisis|on Infinite Earths}} [[Franchise/{{Superman}} Krypton]] the planet was, according to legend, populated by two HumanAlien space travelers named Kryp and Tonn.
** Which may be why marriage between cousins was legal in Silver Age Krypton as Kal-El creepily mentions to Kara once in a discussion that very lightly hits on this topic (they would be Adam and Eve if they weren't content with letting the species die with them).
* Lampshaded on Post-IC Daxam. While the entire Daxamite race descends from Kryptonian explorers and the original, native Aboriginal Daxamite, the whole intermingling is summarized by a single, telltale meeting: a young, male Daxamite inviting a young, sexy Aboriginal Daxamite to join him in "their beutiful new home". Despite speaking nothing but the LanguageOfLove, the couple, and by proxy their two races, elope in the current, Daxamite race.
* A sinister twist on this plot is given in an Creator/ECComics story about the aftermath of a nuclear war. The male protagonist spends the story searching for other life, wondering if there's anyone left, only to find a woman with whom he suspects he could repopulate the Earth. That is, until he learns that the woman is [[spoiler:his sister. What happens next is left to the imagination.]]
** There's one story in the short lived ''Weird Science'' comic series ("A New Beginning" from issue 22) where a man and a woman from the distant future end up becoming Adam and Eve after their time machine leaves them stranded in the past.
* In one of the later ''ComicBook/ElfQuest'' stories, a small family of trolls find themselves stranded in a country where there are no other trolls. Flash forward a few thousand years and there are lots of trolls running around. Incest is hinted at but never stated outright.
** For that matter, if we go by the story ''How Shall I Keep From Singing'', it appears that all elves are descendant from a total of eight High Ones (and one wolf). The "no problem with inbreeding" can probably be explained with [[MindlinkMates Recognition]] weeding out genetic defects.
*** One or two of the prose stories in the ''Blood of Ten Chiefs'' anthologies do name other High Ones that don't appear in ''How Shall I Keep From Singing'', although the total population still wasn't very big.
* Averted in ''ComicBook/YTheLastMan'': While Yorick ''wants'' to do this with his girlfriend Beth, it's pointed out that it would be impossible to do so with just two people. In the end, a combination of [[spoiler:Adams, Eves, and cloning help bring the human race back.]]
* Xemnu the Titan is an alien who has had this goal since he first appeared in the age of [[UsefulNotes/TheSilverAgeOfComicBooks Marvel Monsters.]] Most of his plans have involved transforming human children into beings like himself, although his most recent plot (in ComicBooks/{{She Hulk}}'s comic) involved trying it on She-Hulk in order to mate with her.
* In ''ComicBook/BrightestDay'', [[spoiler:the insane and evil D'kay D'razz wants to revive the Green Martian race with ComicBook/MartianManhunter J'onn J'onzz.]] Even if the plan weren't horribly flawed, she's infertile and deeply in denial about it.
* In a magazine cartoon that allows you to recreate the circumstances of the time (even if you know very little about the 60's) the two survivors of an atomic war are a black man and a black woman. The man is saying to the woman "I'm sure Senator Russell would be pleased that the last two people on Earth are not only Americans, but from Georgia!"
* When Vartox's people were hit with a SterilityPlague, he asked ComicBook/PowerGirl to [[OnlyYouCanRepopulateMyRace help him breed the next generation]]. Power Girl points out the flaws in this plan. Eventually, they cure his people's sterility instead.
-->'''Power Girl''': You didn't ''seriously'' think we could ''repopulate'' an entire planet, did you?
-->'''Vartox''': Given our stamina and power levels, I had assumed...
-->'''Power Girl''': I may have a lot of super-powered body parts, but even us super-heroines have ''limits''.
* ''[[ComicBook/TankGirl Tank Girl: Apocalypse]]'' leads into an Adam and Eve plot, but this is not picked up on in later books.

[[folder:Fan Works]]
* ''Fanfic/HigherLearning'': Shinji and Asuka became this after the [[TheEndOfTheWorldAsWeKnowIt Third Impact]] in the original timeline. [[InvokedTrope A character mentions it several times]]. [[BrotherSisterIncest The logical consequences]] do not go unmentioned.
* ''Fanfic/TheSecondTry'': Asuka and Shinji discuss this during one of the "flashback" chapters.
* In ''[[http://www.fimfiction.net/story/157526/friendship-is-physics Friendship is Physics]]'', Star Swirl the Bearded mentions an unethical experiment he heard about. A male and female child were released into a sealed, artificial environment with no other contact. The two ponies grew up, but while they cared about each other, it never ever occurred to them to mate. The ones in charge of the experiment concluded that the stories of ponykind originating from a single male - female pair were false.

[[folder:Film -- Animated]]
* ''WesternAnimation/{{Rio}}'', the ''other'' Adam and Eve-plotted film of 2010-11 is about a blue Spix macaw who is sent to Rio in order to mate with the last remaining female of his kind.
** Later subverted by the sequel which shows an entire flock of blue parrots hiding in the Amazon.
* The now-canceled {{Creator/Pixar}} animated film ''Newt'', about the last male and female blue-footed newts on Earth forced to mate to continue the species, even though they don't quite like each other to begin with. It was cancelled to avoid DuelingMovies with the above two.
* ''WesternAnimation/{{Nine}}'' [[spoiler:ends with this]] - [[GainaxEnding sort of]]. Bonus points for [[spoiler:the remaining [[PunkPunk stitchpunks]] (9, 7, 3 + 4)]] forming a sort-of Adam and Eve family, [[FauxSymbolism complete with Cain and Abel]]... [[CainAndAbel but not the trope, thankfully]].
* [[SubvertedTrope Subverted]] in ''WesternAnimation/IceAge2TheMeltdown'': Manny and Ellie think they are the last mammoths on Earth, when in fact a whole colony still exists (later seen in the film). However, the pool is probably very small, seeing as mammoths eventually did go extinct.
* In ''WesternAnimation/TitanAE'', when the hero and heroine find the eponymous ship, onboard are genetic samples for long-destroyed Earth's species. Also, in a way, they are a symbolic "Adam and Eve". However, they do not need to populate the new world, mankind has been scattered across the galaxy and thus, they only need to call humans to the new planet. But who says that they won't anyway?
* ''WesternAnimation/AlphaAndOmega'' initially started with Humphrey and Kate being sent to Idaho to repopulate. Humphrey loved the idea more than Kate did.

[[folder:Film -- Live Action]]
* Lampshaded in ''Film/{{Matinee}}'', a film set in the [[UsefulNotes/ColdWar Cuban missile crisis]], when the [[TeenDrama teen protagonists]] get locked in a nuclear shelter during a [[TheEndOfTheWorldAsWeKnowIt bomb scare]]. TenMinutesInTheCloset [[HilarityEnsues Ensues]].
-->"What if we're the only ones left?"
-->"Then we become... Adam and Eve."
* Creator/JimHenson and Frank Oz's ''Film/TheDarkCrystal'' has Jen and Kira, who both thought they were the last [[{{Hobbits}} Gelfling]] until they met the other. And since Gelflings can now live in peace after the Skeksis and Mystics join bodies, they obviously will end up repopulating the Gelfling species.
* ''Film/StarTrekIVTheVoyageHome'' uses the animal version of this trope. This is a bit of a DoubleSubversion, as the animals actually do go extinct, but TimeTravel rectifies the situation by bringing back the tropal two. Also, they aren't being brought forward to breed ''per se'' but to convince an alien probe not to destroy Earth. The {{novelization}} acknowledges that two (or three) individuals aren't enough to repopulate a species, so 23rd-century scientists are going to clone additional whales from cell samples preserved before the species was wiped out. (It's said that they couldn't have restored the species just by cloning, because humpback whales have enough learned behavior that they wouldn't be able to survive without someone to teach them.)
* A rather disturbing variant occurs in ''Film/TwentyEightDaysLater''. It's left unclear whether the leader of surviving military members at the end of the film actually believes they can repopulate the Earth (or just Britain) with the two female survivors they have left, expects to capture more women, or simply decides to keep them to placate his unit while they wait for the end.
* This was the twist ending to ''Series/MysteryScienceTheater3000'' alumnus ''Film/WomenOfThePrehistoricPlanet''.
* The more practical variant (about a dozen Adams and Eves) is brought up in ''Film/TheMatrix'' sequels when [[spoiler: Neo learns that the true purpose of The One is to select 21 women and 7 men who will repopulate Zion after the machines destroy it. The machines know this will work since they've done it ''five times before''.]]
** Not to mention that unplugging humans out of the Matrix is their main means of increasing their numbers. Why wait for babies to grow up when there are ''billions'' of adults ready to harvest?
* ''Franchise/PlanetOfTheApes'':
** This was actually the initial plan in the original ''Film/PlanetOfTheApes1968''. It was scrapped when the only female crew member was killed in the crash landing.
** In ''Film/PlanetOfTheApes2001'', all humans on Ashlar (the name of the planet is given in comics) are descended from [[spoiler:the crew of the crashed ''Oberon'']], which happened over 3000 years before. [[spoiler:The ship]] doesn't look big enough to contain enough humans to sustain a population for that long, especially on a world populated by hostile [[BugWar insectoids]] and dinosaurs that even the well-organized simians have trouble dealing with.
* The plot of the second Creator/EddieMurphy ''Film/DrDolittle'' film revolves around saving a forest from a logging company by getting the native female of a species of bear on the verge of extinction to mate with the only male bear of the same species that could be found. When Dolittle earlier argues that having an endangered bear in the forest should be enough to protect it, he is told that since there is only the one, the species would die out anyway. By that rationale, even getting another bear to mate should be useless for protecting the forest, since there is no way a single mating pair would be viable for saving the species.
* ''{{Knowing}}'' [[spoiler:ends with aliens/angels removing a number of child pairings from the doomed Earth in order to allow humanity to survive on another planet. Slightly subverted in that the angels/aliens actually understand genetics and so have taken far more than one 'breeding pair' but the idea is still there.]]
* ''Star Quest II'' [[spoiler:Aliens using humans to breed alien/human hybrid to preserve the former's species in some form. Problem: they only actually get one couple at the end, the others on the spaceship having been killed.]]

* Prefigured in ''[[{{Robinsonade}} Die Insel Felsenburg]]'' (1731) by Johann Gottfried Schnabel, where the protagonist and his wife populate an entire desert island.
* Will Ferguson's novel ''Happiness (tm)'' mentions this phenomenon from an editor's perspective.
* The Creator/DamonKnight short story ''Not With A Bang'' had two survivors of a biological war, one being an infirm pilot who barely survived the plague and the other being a nurse who had a natural immunity. The repopulating never happens, because she is a very moral woman and they're not married. (And where are they going to find a priest?) After much coaxing and cajoling, she agrees to marry him. [[CruelTwistEnding He then suffers a final attack of the sickness in the one place she would never follow him: The men's bathroom.]]
** It also directly addresses the incest issue - namely, the Adam finds his Eve so annoying he plans to leave her for their first daughter. On the other hand, the story never precludes the possibility that more successful {{Adam And Eve Plot}}s happened.
* Played in ''Literature/{{Animorphs}}'', the book "The Change." There are several Adam and Eve references to Jara Hamee and Ket Halpak, the first two free Hork-Bajir since the Yeerks enslaved them.
* In Creator/RayBradbury's ''Literature/TheMartianChronicles'' stories:
** Subverted in "The Silent Towns". A man wakes up to find that he's been left on Mars by accident after most of the Martian colony has gone back to Earth. He begins dialing phone numbers in a desperate attempt for human contact and manages get in touch with a woman, who he begins to fall in love with (based on their brief phone conversation). When they finally meet, he finds her obnoxious and decides he'd prefer a life of isolation.
** The final story plays the trope fairly straight though, although it leaves it open whether or not "Adam and Eve" will actually meet up (and the human race will continue).
* In Creator/OrsonScottCard's ''Literature/HomecomingSaga'', sixteen people (only four of whom had no genetic connection to someone else in the group) from the planet Harmony were selected to [[EarthThatWas return to Earth]] and re-establish the human population. It was established that since the Oversoul (the [[MasterComputer supercomputer]] that had been running the planet for millennia) had been running a breeding program for just this situation, any recessive traits that would pop up in such a closed population had been bred out of them (it was also revealed that Harmony was not the only such human-populated planet, nor was it the first to return to Earth).
* There was a "short short story" that started to set up this trope in the style of the ''[[Series/TheTwilightZone Twilight Zone]]'' episode mentioned below... then [[spoiler:Adam was accidentally castrated]].
* Subverted in a completely different way by Creator/LarryNiven's short story "What Can You Say About Chocolate Coated Manhole Covers?" The story begins with the main characters at a party having a fun conversation. They speculate on how the Adam and Eve legend could work in real life, purely as an intellectual exercise. They conclude, for the obvious reasons, that one pair could not populate an entire planet. They come up with an elaborate scheme based on RealLife stock breeding techniques, involving many pairs and small groups that are isolated from each other by geography. Then... [[spoiler:an alien kidnaps the protagonists, strands them on a planet orbiting Alpha Centauri, and tells them that they've just figured out the aliens' secret plan for breeding an 'improved' form of human being.]]
* Parodied in a Creator/HarlanEllison short-short story, "The Voice in the Garden" where two humans who are sole survivors of some sort meet each other and decide to do this. The woman is of course named Eve, and the man... George.
* In one of Creator/MichaelSwanwick's "element" short-shorts, an experiment creates a new universe populated by one man and one woman. The man's name is Adam, so naturally the woman takes a new name... Jennifer.
* In Meredith Ann Pierce's ''Literature/TheFirebringerTrilogy'', four hundred years before the books begin, the unicorns' princess and warleader sends four scouts out to seek verification of claims being made by wyverns who want to emigrate to the same territory as the unicorns. Quite some time after the scouts leave, one comes stumbling back with the news the four were sent to get, and notes that one of their companions died along the way. The other two were kept as hostages. Fast-forward four hundred years to the travels of Jan, the books' main character, and when he reaches that part of the world what does he find but [[spoiler: a small, well-protected herd of unicorns who all look ''very'' much like the descendants of the last two scouts. And yes, the incest factor is acknowledged. There's also the implication that these unicorns wouldn't have survived to breed to these numbers if they hadn't had the protection of powerful dragons]].
* ''Literature/TheMetamorphosisOfPrimeIntellect'' [[EndingFatigue ends this way]]. The [[ParentalIncest details]] of which are not left to the [[BrotherSisterIncest imagination]].
* ''Literature/{{Xanth}}'' has numerous examples of this trope with novel types of [[MixAndMatchCritters crossbreeds]]. Typically, it starts with one crossbreed looking for another of his/her kind to mate with. Somehow, he/she finds one, and then a few books later their child goes on a similar quest.
** Toyed with the the first novel. After doing research in Castle Roogna, Trent is the first person to realize that even though there are plenty of humans around, without fresh blood the omnipresence of magic will eventually lead to humanity's extinction. They will keep producing more crossbreeds, or just plain mutate from too much magic (Humphrey is implied to be on his way to becoming this). As inconvenient as the sporadic invasions from Mundania are, they provide fresh, non-magical genetic stock for humanity.
** Eventually subverted in the case of the winged centaurs. When we first meet them, there's just the two of them and this trope seems to be in full force. In later volumes, we find out that they've been gathering volunteers from other races to be transformed by Magician Trent into winged centaurs.
* Averted in "Rescue Run", one of Creator/AnneMcCaffrey's short stories, by the handful of colonists left alive on the Southern Continent of [[Literature/DragonridersOfPern Pern]]. Convinced that all other humans have been wiped out by Threadfall, domineering {{jerkass}} Kimmer forces marriage on the sole remaining female in his group, then refuses to allow any further breeding due to the limited gene pool.
* In ''Literature/TheMagiciansNephew'', Aslan appoints a London cabby and his wife to be Narnia's first king and queen, as well as its first (and only) human inhabitants. Incest issues are averted when their kids grow up to marry wood nymphs and other spirits. This eventually dilutes their bloodline to a point where, when the White Witch returns to conquer Narnia, there's apparently no one left in Narnia who's human enough to contest her claim. After a time, Aslan sends the Pevensie children to do so.
** However, Narnia has a sister country in their ally of Archenland, which was fully populated by humans. Also, the subornate island nations, and the southern enemy nation of Calormene. There's not much explanation for how these people got there, though it might have been similar to how the Telmarenes showed up. Creator/CSLewis didn't expect to write more than the first book, until popular demand had him go back and expand the world.
*** According to CS Lewis' official timeline for the history of Narnia, the first humans - as well as intermarrying with Narnian nymphs and dryads and stars and the like - also quickly spread out within a handful of generations to colonise the until-then mostly barren neighbouring lands of Archenland and Calormene. All the part-humans in those three lands could trace their heritage back to the very first humans to enter Narnia (Frank and his wife). The Telmarines, by contrast, were pirates shipwrecked on an island who accidentally crossed over to a land bordering Narnia, established themselves there as the Kingdom of Telmar, and invaded Narnia shortly after the Pevensies left at the end of ''Literature/TheLionTheWitchAndTheWardrobe''.
* Perhaps the UrExample in (somewhat) modern ScienceFiction is [[Creator/JulesVerne Jules Verne's]] short story "The Eternal Adam" (1911).
* Another classic subversion is "Adam and No Eve" by Creator/AlfredBester, in which the protagonist would be happy to fulfill the plot, but no woman is available. At the end of the story [[spoiler:he drowns himself so that his bacteria will survive in the ocean and [[HollywoodEvolution hopefully evolve into a new sentient species]] one day--needing no Adam and no Eve.]]
* Creator/StephenBaxter's ''The Time Ships'': an expedition from an alternative Great Britain becomes stranded in the deep past after an attack from a time-traveling bomber from their enemies in their own time. They survive, and the protagonist gets to watch them rise from a tiny tribe to a space-traveling civilization as he travels in time, a sequence which is rather unpleasantly like watching mold conquer a petri dish.
* ''Literature/ZForZachariah'': Anne imagines this with Mr. Loomis since they are, or so she believes, the last survivors in America and possibly the whole world following a nuclear war. Turns out he was way ahead of her, leading to AttemptedRape and causing her to run away from him, which forms the catalyst for the ending of the book.
* [[OlafStapledon Olaf Stapledon's]] future history novel ''Literature/LastAndFirstMen'' has at one point the entire mankind reduced to roughly a dozen individuals. They manage to repopulate the Earth with apparently no catastrophic effects from inbreeding. (Then again, the end result is a whole new ''species'' of humanity, albeit a ''better'' species in many ways.)
* Creator/CSLewis' ''Perelandra'': It's another planet's version of Adam and Eve, but they still live in paradise and a world without sin or suffering.
* A mild case occurs in Mikhail Akhmanov's ''Literature/ArrivalsFromTheDark'' series, where an alien race purchases a pair of eagles for their collection and releases them to roam on one of their preserve worlds (they live in orbital habitats). A century later, the eagles number in the hundreds and have adapted to the new world. This happens again, when another pair of eagles are taken from this world to a remote human colony on a world with a much harsher, colder climate. Despite this, the eagles once again increase their numbers and thrive.
* Andrey Livadny's novel ''Ark'' is set aboard a Moon-sized (literally; it's actually the hollowed-out Moon with engines attached) GenerationShip sent a long time ago from Earth to find and collect alien life and put them in specially-adapted habitats. A catastrophe kills the command crew and forces the rest of the humans to live in one of the habitats, leaving the ship's AI to fly the damaged craft. Over time, the humans regress to near-Medieval state and forget their origins. At the end of the novel, the ''Ark'' crash-lands into the sea on [[spoiler:a habitable world orbiting a yellow dwarf, and the first person out is an old shepherd named Noah. How the ship ended up in the past is not explained. It is also not clear what happened to the aliens on-board]].
* The post-apocalyptic story "Mecanoscrit" by Manuel de Pedrolo ends with the creepy variant that the Adam-character dies, and the Eve-character wondering if she would live long enough to have her infant son grow up and have children with ''him'', and a footnote stating that the entire story is a ''historical document.''
** Keep in mind though that the entire story is written from Alba's ("Eve") perspective, save for the last episode, which is stated to be an analysis from a future investigator, who wonders about its authenticity but pretty much states that if what's on the text is true, then Alba is the mother of modern mankind.
* With all the religious symbolism that shows up in Creator/GregEgan's ''Permutation City'', it's only fitting that it should end with [[spoiler:Paul and Maria]] setting off together into their own newly-created universe.
* In ''Literature/HisDarkMaterials'' [[spoiler: Lyra and Will end up being this at the end to ensure that Dust continues to flow down and into the worlds.]] Phillip Pullman even goes further with it and [[spoiler: creates a serpent out of Mary Malone and a garden of Eden type world.]] In this case, what was important was not the mating and reproduction (they didn't produce a child a together from their one time), but the act of intimately connecting to another sentient being and sharing/expressing the love they felt.
* In Bob Shaw's short story ''Call Me Dumbo'', a family live in an isolated cottage, but it turns out that [[spoiler:the parents were the sole survivors of a spaceship crash, and the mother was originally a man on whom the father performed a non-consensual sex change operation and suppressed his/her memory using drugs]].
* The ending of ''Invitation To The Game'' has the characters conclude that the eponymous Game's purpose is [[spoiler: to train them as colonists for a new planet. However, they're TrueCompanions with no romantic interest in each other... then they find another group, and realize several such groups have been placed on the new planet, close enough to form relatively accessible settlements, so there will be plenty of breeding material.]]
* In Creator/PoulAnderson's ''Literature/AfterDoomsday'', the women are well aware of the flaws of this reasoning; though they know that many people have survived, they are also aware that the men outnumber the women and make plans for polyandry so that every surviving woman will have children by several men.
* The Creator/GeneWolfe short story "Procreation" has a variant, and indeed a [[{{Pun}} Shaggy God Story]]: the writer creates a miniature Universe. Deciding to let the creatures within know how they came to be, he and his sister ('Sis') write an account of the creation and drop it into the Universe. They don't know what to call the book, so just write their names on the cover. [[spoiler: 'Gene' + 'Sis']]
* "Born of the Sun" is a 1934 short story that is probably the reason why most editors had a policy of rejecting stories with this twist on sight. It starts out fine enough, with the heroes managing to build a spaceship to escape the Earth before it is destroyed, and they originally plan to defy this trope by saving as many people as they can. Unfortunately, it seems like the writer thought that he had no choice but to use the trope for this kind of story, because [[spoiler:in the last few pages, the villain manages to whip up everybody except the male and female leads into a religious fervor and destroy the original spaceship, even though most of these people were volunteers who showed no sign of believing in the villain's cult at any earlier point in the story.]] Fortunately, the male and female lead have a smaller spaceship which they use to leave the Earth, but they are all alone. The implication is that their descendants will populate the universe, but then it runs into FridgeLogic that [[EsotericHappyEnding they wouldn't have enough genetic diversity to keep the species going]], which the author seems at least vaguely aware of because of the aforementioned spoiler.
* During the end of ''Literature/SeaOfThePatchworkCats'', with Jen digested and Kara killed by [[spoiler:the Queen of Cats]], Conrad and Jaji are now the last human on the planet (if Jaji even counts), the ending having Jaji pregnant while Conrad contemplates the future.
* The ending of ''Literature/TheMazeRunner'' trilogy. Out of the entire human race, only a select few are able to resist the influence of the Flare virus. They are thus humanity's last hope to rebuild the Earth. However, that last few actually number several hundreds, which is far more realistic than the usual application of this trope.


[[folder:Live-Action TV]]
* ''Series/TheTwilightZone1959'':
** A classic, and rather literal, example can be found in the episode "Probe 7, Over and Out". An astronaut named Adam Cook crash lands on what appears to be a barren planet. Equipment failures keep him from radioing his homeworld, but he receives transmissions that indicate it has blown itself up in a nuclear war. While searching the planet, he comes across a woman, also stranded there. They can't communicate in words, but they make due by gestures and drawing in the sand. Eventually, it comes out that she's [[EarthAllAlong called the planet "Irth"]] and her name is... Eve Norda.
** The episode "Two" had Charles Bronson and Elizabeth Montgomery as the (as far as we know) sole survivors -- from opposite sides, no less -- of a city-destroying war between two unnamed factions. Creator/RodSerling's narration in the episode purposefully says that it could be set at any time during the past ''or'' future, and that "[[TranslationConvention The signposts are in English so that we may read them more easily]]".
* ''Series/TheOuterLimits1995'':
** The {{revival}} did this in a two-part story with the episodes "Double Helix" and "Origin of Species". The sample size was 8 students and one professor, and it is immediately pointed out that they could not possibly repopulate the planet alone. It's {{hand wave}}d by the [[spoiler:spaceship that took them into the future, which altered their genes to ensure maximum diversity and created hundreds of babies to further pad the gap]]. Subtly played with in the fact that both the professor and his son are exempt from being "Adams" due to a genetic disease (and are therefore vaporized), [[spoiler:but live on as holograms to assist their friends]].
** The episode "Phobos Rising" also hints at this plot, with the Earth possibly destroyed and only two Mars colonies with a combined population of less than fifty as survivors. Unfortunately, accidents fueling EnforcedColdWar paranoia end up destroying both colonies with only a pair of {{defect|ingForLove}}ors surviving. [[spoiler:Subverted in the final few minutes, when the surviving pair on Mars receive a transmission from Earth, telling them that the Moon was accidentally destroyed and in the wake of the devastation on Earth, both sides have called a truce.]]
* The ''Series/SevenDays'' episode "Adam & Eve & Adam" has a NeutronBomb [[ApocalypseHow obliterate humanity]]. [[TheHero Parker]], [[HotScientist Olga]], [[{{Geek}} Owlsey]], & Army officer Major Jones have to journey back to Project Backstep. At one point, Owlsey kills Jones and tries to kill off Parker to start an Adam and Eve Plot with Olga. Of course, at the time, he was AxCrazy from radiation poisoning. Parker, [[OncePerEpisode per his usual shtick]], must SetRightWhatOnceWentWrong.
** Several episodes feature the destruction of nearly all life on Earth. In fact, in one case, Parker is the only survivor of a plot by an alien conveniently nicknamed "Adam" and has to manually start the Sphere to backstep.
* ''Series/DoctorWho'': The villain's plan in "[[Recap/DoctorWhoS22E5Timelash Timelash]]" is essentially to cause this trope with his own planet -- and he wants [[MsFanservice Peri]] to be his Eve.
** Also part of Luke Rattigan's plan to take his group of genius students to another planet in recompense for selling Earth to the Sontarans - he's even drawn up a breeding schedule! Needless to say, the one girl in the group isn't too happy with the idea.
** Implied to be the fate of the Tellers in "Time Heist."
** Suggested by Clyde in an episode of ''Series/TheSarahJaneAdventures''. [[AllWomenArePrudes Rani has other ideas.]]
* Played out in the finale of the 2000s ''Series/{{Battlestar Galactica|2003}}'', wherein [[spoiler:the Colonists become the distant ancestors of the modern human race, and [[HalfHumanHybrid Hera Agathon]] is played up as being the Mitochondrial Eve.]]
* Done in an episode of ''Series/{{Dinosaurs}}'' with unnaturally cute, little furball-type animals.
* TruthInTelevision example: One episode of ''Hoarders'' came close to this trope, featuring a man with over 2000 fancy rats living free in his house. He'd accidentally allowed his one male and two female pet rats to escape, months earlier, and hadn't had the heart to let them starve or set traps, with [[ExplosiveBreeder inevitable consequences]].
* ''Series/StarTrekTheOriginalSeries'':
** The original pilot, "The Cage", has a group of RubberForeheadAliens who try to use their LotusEaterMachine to convince Captain Pike to play Adam for them with an Eve of his choice.
** The story was expanded in "The Menagerie", using footage from the pilot. The aliens, called the Talosians here, release Pike and his crew after finding that humans "have a hatred of captivity". The "Eve", named Vina here, must stay behind, however, as leaving would cause her to die from the injuries sustained by her true body that are suppressed by their technology. In the present day, with Pike being an old and invalid man, they offer to let him live with them again, where he can gain his youth and health back and live with Vina. He accepts, and it remains ambiguous whether the Plot ever succeeded.
** Another episode has the crew encounter a disembodied creature known as Sargon, who claims that the human Adam and Eve were explorers from his race. When the humans refute this claim by citing evolution, Spock admits that the Vulcan creation myth also fits Sargon's story.
* An episode of ''Series/StargateUniverse'' reveals that, thanks to a TimeyWimeyBall, an alternate version of the ''Destiny'' crew (minus Rush and Telford) got thrown 2000 years into the past and had to set up a settlement on planet Novus. When "our" ''Destiny'' crew encounters them, they're a formerly thriving civilization of millions, forced to abandon their planet when a black hole was detected approaching the system. There is no mention of any inbreeding, although it is possible the crew's descendants have figured out how to maintain genetic diversity, even though all of them are descended from a few dozen people.
* In ''Series/StargateSG1'', the Alpha Site was intended to {{invoke|dTrope}} this trope should an alien invasion overcome Earth's defenses. This was a real threat in the early seasons (they actually started moving personnel offworld in "The Serpent's Lair"), but the threat diminishes after Earth first gains Asgard military protection, then becomes a spacefaring power in its own right.
* Kaya, a water nymph, uses Malone for one in ''Series/SirArthurConanDoylesTheLostWorld''. [[spoiler: It doesn't stop Veronica from getting the wrong idea.]]
* ''Series/KamenRiderGaim'' offers a twist on the concept: [[spoiler:At the end of the series, [[TheHero Kouta]] and [[TheChick Mai]] have evolved beyond humanity and gained the power to shape the world to their will. Rather than destroying the planet he fought so hard to protect, Kouta uses his new powers to create a portal to a distant, uninhabited planet and states that '''that''' is the world he'll shape. DJ Sagara, the story's Satan analogue, urges them to "be fruitful and multiply" after [[LampshadeHanging openly noting the irony of his doing so]].]]
* In ''Series/TensouSentaiGoseiger'', TheMovie involves the heroes trying to protect an "Eve" figure whose home planet was destroyed by an ArtifactOfDoom that the villains are now trying to get their hands on. At the end of the movie, "Adam" returns and takes her back to their planet for them to begin rebuilding their world.
* In ''Series/TheLastManOnEarth'', after Carol finds Phil, she takes it as a matter of course that they'll have to mate to repopulate the species. Phil, who's taken a quick dislike to her, refuses. (It's two years after ThePlague wiped out the human race.) And then [[spoiler: another woman and man show up to complicate things.]]
* Though not quite down to two people, the original "Survivors" featured humanity wiped out except for 1 in 10,000 people. When Charles was first introduced, a defining character trait was his belief that the survivors needed to focus on breeding to rebuild the human species (this trait was later downplayed once he became a main character).
* On ''Series/{{The 100}}'', when Kane is considering [[PopulationControl killing large segments of the Ark's population]] [[ColdEquation to conserve oxygen]], he says he's willing to reduce the Ark to "a cosmic Adam and Eve" if necessary.


* "Man Gave Names To All The Animals" by Music/BobDylan from ''Music/SlowTrainComing'' is based on Adam naming all the animals in the Garden of Eden. It's rather childlike in nature and has often been called one of Dylan's worst songs in terms of lyrics.
* "Snake" by Music/PJHarvey from ''Music/RidOfMe''
--> ''You snake (You snake)''
--> ''I ate (I ate)''
--> ''A true (A true)''
--> ''Belief (Belief)''
--> ''Good Lord (Good Lord)''
--> ''That fruit's (That's fruit's)''
--> ''Inside (Inside)''
--> ''Of me (Of me)''
--> ''Oh Adam (Oh Ad-)''
--> ''Please (-am please)''

[[folder:Mythology and Religion]]
* Literature/BookOfGenesis:
** The {{trope namer|s}} is the story of Adam and Eve. After the first man and woman are created, God's first instructions to them is: "Be fruitful, and multiply, and replenish the earth".
** Implied in chapter 4, which identifies three children of Adam and Eve: Cain, Abel, and Seth. After Cain kills Abel, Cain moved east to the land of Nod, where he married someone and had at least one son, Enoch. The identity of Cain's wife is a matter of much debate, along with how he and Seth managed to populate the Earth on their own. Explanations include the following:
*** Literature/TheBible is unclear how much time passed before Cain killed Abel, and it is clear that there were other children - both sons and daughters. Daughters are not tracked in the Bible unless they're very, very important. Sons are only tracked if they're relevant to the plot (Adam to Noah to Abraham to David to Jesus). Seth is not born till after Cain and mentioned as a replacement for Abel only because that's the bloodline to Noah. It's actually AllThereInTheManual, if you can read it in Hebrew. Anyway, the implication is that Cain married one of his sisters, which was considered acceptable because of the necessity to be fruitful and populate the Earth.
*** An alternative explanation is that chapters 1 and 2 of Genesis are in chronological order instead of different versions of the same events. That is, the people Cain married into were the ones created on the sixth day of creation and a separate creation from Eden and Adam's bloodline. This is part of a concept known as "polygenism."
** After TheGreatFlood, humanity is reduced to eight people (Noah, his wife, Noah's three sons and their wives) and all others are descended from this family.
* Myth/NorseMythology: Several instances are mentioned or implied in Literature/{{the Eddas}}:
** When the Aesir kill Ymir, all the giants drown in his blood except one couple, Begelmir and his wife, from whom all later giants are descended (''Literature/ProseEdda'').
** The first humans are created by Odin and his two brothers as a couple, Ask and Embla. Suspiciously, their names begin with the same letters as Adam and Eve, which could be an allusion to the Literature/BookOfGenesis (''Literature/PoeticEdda'', ''Prose Edda'').
** In Ragnarok, all humanity is destined to perish except a single couple, Lif and Lifthrasir, who will repopulate Earth (''Poetic Edda'', ''Prose Edda'').
* Averted in the Myth/ClassicalMythology version of The Flood: one man and one woman are left, however they are asked by the gods to throw earth over their shoulders, and this earth turns into sufficient men and women to actually repopulate the world.
* ''[[Literature/TheMabinogion Mabinogion Branwen verch Llyr]]'': The Britons invade Ireland and kill everybody except five pregnant women hiding in a cave. The five women bear five sons who repopulate the island. Hence the five provinces of Ireland.

* In the BBC RadioDrama ''Earthsearch'', the crew of the ''Challenger'' end the series by giving up the search for their long-lost home planet Earth, settling instead on the planet "Paradise", which they vow to make "their own Earth" -- it's much like their Earth, except that it's two-thirds covered in saltwater oceans, has four seasons, and is the third planet from its sun. Cleverly, throughout the series they had dropped hints that "their Earth" was not the same planet as ours, but then covered them up with Expospeak: for example, the other planets of their solar system have different names from ours, but as soon as this is revealed, it is mentioned offhand that the planets had been renamed. Likewise, we are told that their Earth was the second planet from its sun, but we are told this by a computer which is speculating wildly based on inaccurate information. To keep the Shaggy God Story going, early in ''Earthsearch 2'', the crew loads breeding pairs of animals into a shuttle to wait out a global flood.
* From a sci-fi series called "X - 1" (''[[PunctuatedForEmphasis X! Minus! One!]]''): A scientist in CaptainErsatz-East Germany, along with his assistant Alan and [[MadScientistsBeautifulDaughter beautiful daughter]] Ava have developed a way to shrink things to subatomic size and are planning to use it to smuggle aid and, eventually, people. Fascist government thugs break into the lab and [[PunnyName Alan and Ava]] are forced to hide in the shrinking machine, which gets turned on either by accident, a plan by the scientist, or because the leader of the fascist thugs demanded a demonstration. Alan and Ava are briefly seen exploring the surface of a planet-sized electron, which they liken to a desert with the central atomic cluster as its sun (I know I [[ArtisticLicensePhysics fail physics forever]] and [[ScienceMarchesOn atoms aren't described that way anymore]]). [[spoiler:When the scientist reverses the machine, to his surprise Alan and Ava are gone but a mysterious voice issues in their place, saying that they eventually populated the electron-planet and it was a peaceful and prosperous land for thousands of (atomic) years, and to make sure the peace lasted beyond their deaths they [[Literature/TheBible wrote a book of instructions]] for their descendants. The scientist is incredulous that Alan and Ava are both long-since dead and the parents of a peaceful race; unfortunately I can't recall the fascist thugs' reaction.]]

[[folder:Video Games]]
* The adventure game ''VideoGame/LostEden'' features two main human characters -- Adam and Eve, living in a world where dinosaurs rule over humans. At the end of the game, it is revealed the dinosaurs will go extinct and Adam and Eve will lead humans into an age where they are the dominant species.
* Downplayed in ''Franchise/{{Halo}}'': When the [[{{Precursors}} Forerunners]] were forced to fire the Halos and wipe out all sentient life in the galaxy in order to stop [[TheVirus the Flood]], they stored as many specimens from different species as they could on the Ark, a giant installation located far away from the Halos' effects. After the Halos had fired, these specimens were sent back to repopulate their various homeworlds.
* In ''VideoGame/DukeNukem: Land of the Babes'', the invading aliens [[MarsNeedsWomen kill all the men]], and LaResistance calls up Duke from their past to help. [[http://youtube.com/watch?v=E6__xhci6lY&fmt=18 The ending]] shows a clear Adam and Eve Plot, although in this case it's more an "Adam and [[LadyLand Eve-land]]" Plot.
* The good ending of ''VideoGame/OdinSphere''. [[spoiler:After TheEndOfTheWorldAsWeKnowIt, Oswald and Gwendolyn are the only two humans left alive and presumably, the ones who repopulate the devastated planet. Well, Velvet and Cornelius survived it too, but they're not exactly human anymore.]]
* Referenced in ''VideoGame/HalfLife2'' (one of the episodes, anyway) where the [[GeniusDitz well-intentioned]] Dr. Kleiner mentions on the monitors previously used for Breencasts (and which are therefore presumably scattered strategically worldwide) that since the Combine suppression field that had been inhibiting pregnancies was now gone, that those so inclined might as well set about replenishing the human population. Alyx incredulously asks the question that was likely in every player's head at that moment: "Did he just tell everyone to... get busy?"
* ''VideoGame/ShinMegamiTenseiI''. [[spoiler: There's a possibility that the characters actually are {{Reincarnation}}s of Adam and Eve. At least, Lillth thinks so.]]
** ''VideoGame/ShinMegamiTenseiII''[='s=] neutral ending has the Heroine say this is what they need to do as they walk off into the sunset.
* ''VideoGame/ShadowOfTheColossus'' [[spoiler:The bridge to the Shrine of Worship is destroyed as Lord Emon and his men escape. That just leaves Mono and Wander to repopulate the Cursed Land.]]
* Parodied in ''VideoGame/Left4Dead'':
-->'''Zoey''': Wait, that makes me the last woman on earth... Shit.
** And in the sequel, when [[TheChick Rochelle]] dies:
--->'''Nick:''' There goes repopulating the earth.
* ''VideoGame/RadiantSilvergun'' where at the end it turns out that [[spoiler:the first humans on Earth are the clones of last humans on Earth who were sent back in time for ResetButton]].
* Averted in ''Franchise/MassEffect'': [[spoiler:The last hundred or so surviving {{Pr|ecursors}}otheans were put into [[HumanPopsicle stasis]], but the genocide of the Protheans by the [[EldritchAbomination Reapers]] lasted centuries. In order to conserve energy, Vigil, the pseudo-AI watching over them, had to initiate a contingency program that would [[CryonicsFailure shut down stasis pods]] one-by-one, starting from the lowest ranking individuals upwards. By the time the genocide ended centuries later, only the top dozen Protheans remained, which, as Vigil pointed out, [[ShownTheirWork was far too few to repopulate the species]].]]
** ''VideoGame/MassEffect3'' has the appropriately named Eve, [[spoiler: the sole female krogan who has been cured of the genophage thanks to Maelon's experiments in ''VideoGame/MassEffect2''. This makes her the prime candidate for starting the krogan's repopulation efforts]].
** [[spoiler: In Mass Effect 3 if you sided with Wrex and released the cure for the Genophage, he is considered a Prime male for breeding with the females of his species.]]
* Subverted in ''VideoGame/{{Fallout 3}}'': The Overseer of Vault 101 refuses to let anyone out of the Vault because he thinks it's the last settlement of humans uncorrupted by the chaos outside, but it's possible to convince him otherwise by pointing out that the Vault doesn't have enough genetic diversity to survive.
* ''VideoGame/AssassinsCreedII'' shows a different interpretation of Adam and Eve. In the games' story, [[spoiler:humanity originally began as a slave race created by a highly evolved and [[SufficientlyAdvancedAlien technologically advanced (possibly alien) race]]. If you find all the glyphs and unlock the hidden video, you see a 20 second clip of Adam and Eve [[LeParkour parkouring]] their way through a factory and escaping. If you look above in the Mythology section you'll see this is closer to the Summarian Adam and Eve than the Biblical one.]]
** Actually, [[spoiler:they led a [[TurnedAgainstTheirMasters human revolt against the "gods"]] with the help of a Piece of Eden]].
* The ExcusePlot of ''VideoGame/{{Volfied}}'' ends with this.
* In ''VideoGame/ChaosRings'' and its prequel ''Chaos Rings Ω'' the entire purpose of the Ark is to set one up using the best possible BattleCouple [[spoiler:to breed humans capable of defeating an EldritchAbomination]]. However, the genetic problems with this trope are addressed in the first game: in Ayuta's story, there's a bit where it's claimed that [[spoiler:the First Couples are dropped off at an era with plenty of other humans for breeding.]]
* ''VideoGame/TheLegendOfZeldaSkywardSword'' ends with [[spoiler:Link and Zelda, rather than returning to Skyloft, [[IChooseToStay deciding to remain in what would eventually become Hyrule]]]]. While it's probably safe to assume they won't be the only ones to repopulate the surface ([[spoiler:the cloud barrier between it and Skyloft has disappeared, making it possible for anyone to come]]), the Adam and Eve symbolism is still very apparent.
* After you clear the first Act of each area in ''VideoGame/ActRaiser'', the Master creates a temple and two people, a man and a woman, to lead the local civilization, for the most part these two people are the ones who specifically address you when you listen to the peoples' prayers.
* ''VideoGame/XenobladeChroniclesX'': The Orphe are reduced to a mere five individuals by the time humanity rescues them from the Ganglion. Fortunately, due to Orphe reproducing via "fission" rather than sex, there isn't any danger of inbreeding. Unfortunately, they require a specific chemical (senirapa water) to use as a catalyst for their reproduction, and they only have a few cups of it left. Once they find a way to produce more, their population grows extremely rapidly.

[[folder:Western Animation]]
* In ''WesternAnimation/AvatarTheLastAirbender'', it's stated that airbenders still existing is important both for the balance of the nations and so the next Avatar has someone to teach them, implying Aang would have to restore the Air Nomads with his descendants. This was lampshaded in a video at the San Diego [=ComicCon=] 2008. However, in ''WesternAnimation/TheLegendOfKorra'', set 70 years later, we see even if only one parent is an airbender the children still can be: one of Aang's children with Katara (a waterbender) was an airbender, and three of ''his'' children with his non-bender wife are airbenders. (No word yet on if his youngest is one, he's only a baby after all.)
** Beginning in season 3 of ''Korra'', some non-benders start to develop airbending abilities following the spiritual convergence, which neatly sidesteps the mating problem.
* Subverted in ''{{WesternAnimation/Futurama}}'', where Leela falls in love with someone she believes to be [[ActorAllusion another cyclops]]. Even when [[{{Jerkass}} his personality gets to be too much to bear]], Leela feels that she owes it to her species to repopulate. As it turns out, [[spoiler:Alcazar was a shape-shifter - who had fooled four other girls]]. After Fry exposes him, the [[WeddingDeadline wedding is called off]]. Of course, it later turns out that Leela is [[spoiler:really a sewer mutant]].
** In the comics, after the Professor teleports Earth's population to the dinosaur age, minus Fry, Bender, Leela and Cubert, the Omicronians show up to salvage the uninhabited Earth, unless our heroes can display one hundred Earthlings, proving Earth still has people. This trope may have been Fry's idea, earning him a slap from Leela.
--->'''Fry''': Okay, fine. Then YOU come up with another way for us to repopulate the planet.
** Leela seems to attract this a lot. [[spoiler:Of course, when the Adam in question is [[{{Jerkass}} Zapp]] [[SmallNameBigEgo Brannigan]]...]]
* ''WesternAnimation/AdventureTime'' has a [[SubvertedTrope different]] take on the typical Adam and Eve plot, in the episode "You Made Me!". Lemongrab refers to his creator as "his Glob" (his God.) She spends the whole episode trying to figure out how to help him. At the end of the episode, Princess Bubblegum makes Lemongrab a clone of himself, so he won't be alone. The whole plot is reminiscent of God making Eve for Adam to prevent Adam from being the only one of his kind. The whole episode revolved around existential themes, and the idea of having "the perfect mate" who makes one feel whole. Whether or not the relationship between the two Lemongrabs was [[HoYay romantic]] or [[HeterosexualLifePartners platonic/brotherly]] love is up to the viewer.
** Later episodes make it clear that they view each other as brothers and address each other as such...until the first Lemongrab eats the second, [[CainAndAbel making this into another Biblical story...]]
* The very end of ''WesternAnimation/AeonFlux'''s series finale, ''End Sinister''.
* In the episode of ''WesternAnimation/FamilyGuy'' "Friends Without Benefits", Meg daydreams that she and a boy she's crushing on are the last two humans after the Earth is destroyed. The boy decides that they should repopulate. And the two of them start making out in their spaceship.
* Implied at the end of the ''WesternAnimation/LittleEinsteins'' episode "Knock on Wood", where a male ivory-billed woodpecker (a bird that is believed to be extinct in RealLife) finds a friend...in the form of a ''female'' ivory-billed woodpecker.

* ''Webcomic/EightBitTheater'' {{lampshade|Hanging}}s the [[http://www.nuklearpower.com/2007/06/21/episode-860-origin-of-the-species/ genetic problems of this trope]].
* In ''Webcomic/{{Freefall}}'', Florence laments that fourteen individuals do not provide enough genetic diversity for a species to survive, and her main objective in life is to ensure more Bowman's Wolves (at least five hundred) are artificially created before it's too late.
* Parodied in the ''Webcomic/SluggyFreelance'' storyline "28 Geeks Later," when a budding ZombieApocalypse has taken over a research facility, [[http://www.sluggy.com/comics/archives/daily/20050726 with several people trapped inside]].
-->'''Soldier:''' We have to repopulate the Earth!
-->'''Zoe:''' Say ''what?!?''
-->'''Soldier:''' Well, we have to repopulate the facility at least. It's the only way we'll outlive them as a species.
-->'''Zoe:''' Is everybody here on Crazy-Stupid gas or something?
-->'''Soldier:''' This is no way to start a first date!
** This is even funnier if you know that Zoe is the Greek version of the name Eve (they both mean "life").
* In a ''Faans!'' story set AfterTheEnd, Tim and cloned copies of his buddies are all that are left to repopulate the Earth. Much attempt is made for genetic diversity but the kids are naive and eventually a brother falls in love with his half-sister. [[spoiler:Of course, Earth is just fine; "Tim" is as much a clone as the others, just with transferred memories.]]
* In an abandoned ''Webcomic/TheOrderOfTheStick'' storyline in the newest book, "Don't Split The Party", [[spoiler: Elan tries to set up Lien and Hinjo to breed a new generation of paladins. Lien and Hinjo are understandably annoyed with this because A) Elan obviously does not understand how paladins are created, B) Hinjo outranks Lien and sees it as a breach in behavior, and C) Lien already has a boyfriend, one that isn't a spoon fed nobleman.]]
** [[spoiler:Plus, there were "many" paladins that were away from Azure City the day of the battle... but we don't hear about them much. And many paladins don't work for Azure City.]]
* ''Webcomic/{{Educomix}}'': When Jessica is in the Garden of Edam, she and Adam are the only humans in existence.
* Mentioned in ''Webcomic/{{Homestuck}}''. Dirk and Roxy are the only two living humans in a post-apocalyptic future, and Roxy, who has a crush on Dirk, entertains fantasies of the two of them repopulating the species together. Unfortunately for her, Dirk seems to be gay. Fortunately, however, repopulating the Earth in this fashion turns out to not actually be necessary.
** It turns out not to be necessary because, as it turns out, [[spoiler: the ectobiology machines are capable of producing more people, and the new world the kids are supposed to make will already be populated once they create it.]]

[[folder:Real Life]]
* Cheetahs. From Wikipedia (with a Scientific American [[Administrivia/ThereIsNoSuchThingAsNotability citation]]):
-->"The cheetah has unusually low genetic variability and a very low sperm count, which also suffers from low motility and deformed flagellae. Skin grafts between non-related cheetahs illustrate this point in that there is no rejection of the donor skin. It is thought that it went through a prolonged period of inbreeding following a genetic bottleneck during the last ice age."
** The present-day population of cheetahs is low enough to put them into this category again. So it's good to know that this endangered species has survived such a problem in the past.
* Northern Elephant Seals, which had a population that fell to a number somewhere in the 30s during the 1890s but now are no longer endangered (residing in the "least concern" category). However, it should be noted that [[SexGod Male Elephant Seals are able to impregnate up to 50 females every mating season]].
* The stereotypical hamster (the golden/Syrian) is actually endangered in the wild. Virtually every domesticated Hamster is descended from a single litter captured in the 1930s.
* Genetic studies trace the native fruit flies of Hawaii to a single gravid female, which was probably blown there by a storm.
* In some areas, humans. Although there was never a colony or town that came entirely from a single couple, there is what is called the "[[http://en.wikipedia.org/wiki/Founder_effect Founder Effect]]", where having a overly small gene pool increases hereditary traits, usually leading to a higher rate of certain diseases or disorders. For example:
** For centuries, Martha's Vineyard had an abnormally large number of deaf people. This was because up until the 20th century there were rarely any outsiders (read: tourists) showing up, so it was rare for any new genes to be introduced into the pool.
** Polydactyly (having more than 5 fingers) is more common in the Amish than elsewhere, for similar reasons (endogamy means small gene pool).
** 75-80% of Fundamentalist Mormons (not to be confused with the 'regular' Mormons) are related in some way to Joseph Smith or John Barlow. There is also an unusual amount of fumarase deficiency in Mormon populations, the result of Fundamentalists continuing to practice polygamy and endogamy.
** In 1775, a giant typhoon hit the Micronesian Island of Pingelap. Only 20 people survived. One of them was a carrier for achromatopsia -- "total color-blindness". Since achromatopsia is a recessive genetic disorder, over time more and more islanders have inherited the gene, and thus also a greater number have inherited color-blindness. Today, 10% of the population is completely color-blind, and 30% more of the population carries the alleles that could cause their children to be color-blind.
** The modern day inhabitants of Pitcairn Island, all descendants of the ''Bounty'' mutineers, are subject to a variety of genetic defects associated with several generations of inbreeding.
** The [=CCR5=]-Delta 32 mutation is descended from Europeans during the time of the Black Death. It's theorized that those that had the mutation then were immune to the disease, thus after it passed, a significant number of Europeans left had the mutation. It's almost unknown in African and indigenous American populations, but about 10% of European-descended humans have the mutation. It would be unremarkable now, except that if you have two parents with the mutation, you have immunity to some strains of HIV, for now. (Wiki/{{Wikipedia}} has more under http://en.wikipedia.org/wiki/CCR5#HIV .)
** 5-alpha-reductase deficiency, a very rare genetic condition where a child is born with a female appearance but develops male genitalia at age 12, has a very high incidence rate in areas of the Dominican Republic, where nearly everyone with the condition is descended from a single colonist dating from the days of Columbus.
** The high proportion of people suffering from Huntington's disease (a disease that is hereditary but doesn't have major negative effects until after reproductive age) in the Lake Maracaibo region of Venezuela is believed to be a result of one of the ten or so women who first immigrated there from Europe having the disease.
* Geneticists have posited that ''all'' modern day ''Homo sapiens'' were descended from one woman dubbed as the Mitochondrial Eve who lived in Africa around 200,000 years ago. But this is really a subversion as all scientists are very certain that she is in no sense of the word comparable to the biblical Eve: she was not the first woman, she is simply the earliest woman to which geneticists can trace, and she just happen to be lucky enough that her daughters were able to produce an unbroken line of descendants to the present day while the offspring of her contemporaries died out in the interim.
** "Died out", in this context, could mean "produced only male offspring for a generation", not actual extinction of the bloodline. As mitochondria are inherited solely through the female line, having sons doesn't do anything to preserve these organelles' genes.
** In fact, the Y-Chromosomal Adam was dated to live about 130,000 years ''before'' Eve.
* The Toba catastrophe theory, called so after a volcanic eruption some 75,000 years ago, states that humans themselves suffered a severe population bottleneck (down to some two or ten thousand of humans on Earth) due to aforementioned volcano. Not exactly Adam and Eve Plot, but as close as we ever got.
** There are some (hotly debated) theories that say after this eruption, for a short time there were as few as thirty some-odd breeding human females on the planet. Most estimates put the count as higher, but still considerably low.
* This is touted as an actual newspaper headline, in the vein of the stuff sent in to ''Series/TheTonightShow With Jay Leno'' for his "headlines" segment: '''Panda Mating Fails; Veterinarian Takes Over'''.[[note]]This is the kind of headline you'd find on Website/{{Fark}}, actually[[/note]]
* Biology classes introducing evolution use this trope to describe Malthusian population growth, explaining how a mated pair of sparrows (or whatever) could hypothetically produce enough descendants to cover the Earth within a shockingly short period of time.
** Similar examples of a pregnant cat or dog producing thousands of descendants are used by animal welfare groups, to encourage spaying or neutering of pets.
* This has happened with more than one endangered species. The [[http://en.wikipedia.org/wiki/California_Condor California Condor]] was down to 22 birds by the time all birds left in the species were captured and taken to zoos. There are just over 400 alive today, about half in the wild.
* The population of [[http://en.wikipedia.org/wiki/Przewalski%27s_Horse Przewalski's Horse]], the only truly wild horse in the world, is descended from nine horses held in captivity in 1945. 1500 horses are alive today in zoos and in the wild of Mongolia.
* On Île Haute, in the Kerguelen Islands, a male and female mouflon sheep were introduced in 1957. The current population, descended only from that pair, fluctuates between 250 and 700 individuals, and shows far more genetic diversity than had been expected.
