->'''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: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]]

[[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 -- Animation]]
* ''WesternAnimation/{{Rio}}'', the ''other'' Adam and Eve-plotted film of 2011 is about a blue Spix macaw who is sent to Rio in order to mate with the last remaining female of his kind.
** [[spoiler: Later subverted by [[WesternAnimation/Rio2 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]]

[[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.]]

[[folder:Music]]
* "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)''

[[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.
[[/folder]]

[[folder:Radio]]
* 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:Web Comics]]
* ''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]]

[[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.
