Page Type: trope
In real life, hybrids between different species are often sterile, which precludes the possibility of their further hybridizing. But there are some exceptions and if there are enough hybrids of the same two species they might be able to produce a new species combining the two.
In Real Life this is called hybrid speciation.
- Monstress: Arcanics are the descendants of the immortal Ancients and their assorted human lovers over the past few centuries. Most consider them to have become a distinct species.
- The War Gods: Half-elves aren't quite a stable sixth race, but they come close. If two half-elves have children, those kids will be half-elven even if the elven ancestors are several generations back. (A half-elf - elf pairing also produces half-elven children, but half-elf - human means the children are humans.)
- Chronicles of the Emerged World: When humans first entered the then elven-dominated Great Land many centuries in the series' past, the intermingling of the two races led to the creation of the race of the half-elves. While the elves eventually left the Great Land, the half-elves had by then become numerous enough to form their own nation in the Land of the Days and become the Great Land's dominant race... at least until their near-total genocide by Aster the Tyrant shortly before the start of the series.
- The Night Land: In an intentional horrifying example of this trope, numerous of the Night Land's monstrous inhabitants arose through the intermingling of humans with the entities that entered it many millennia in the book's past, as the Sun slowly went out and the Earth began to die. The Giants are the example most focused on in the book, described as a species of hideous, towering, warty humanoids "fathered of bestial humans and mothered of monsters".
- Oath Of Swords has the half-elf Purple Lords.
- Dungeons & Dragons:
- Tieflings, aasimar and genasi are three species of plane-touched humanoids (plane-touched being a general category for mortal creatures with some inherent connection to other planes of existence) descended from the interbreeding of humans and planar beings. While the origins of each race lie with direct cases of humans having children with, respectively, fiends, celestials and various types of elementals, they all became self-sustaining, if somewhat uncommon, races long in the past. In the various settings' modern day, all tieflings are born to tiefling parents, all aasimar to aasimar parents and all genasi to genasi parents.
- Forgotten Realms:
- Fey'ri, maeluths, tanarukks, wisplings and mur-zhagul are a group of minor races introduced as counterparts of sorts to the tieflings. They differ in their mortal ancestors — sun elves, dwarves, orcs, halflings and trolls instead of humans, respectively — but they are identical in all major respects, being the descants of the children of mortals and various sorts of fiends who became their own self-sustaining species long ago. Fey'ri in particular are highly proud of their bloodlines, and make a point of only ever breeding with other fey'ri.
- On a similar note, worghests are a species descended from the intermingling of goblins with barghests, Lawful Evil shapeshifting Hellhounds.
- Eberron: half-elves are considered a distinct race as in most cases their purebred human and elf ancestors were several generations ago. There are even two Dragonmarked Houses composed of half-elves.
- In Pathfinder half-elves are sometimes Half-Human Hybrid but in some countries with a significant population they may be born of two half-elven parents.
- In Starfinder orcs were almost entirely confined to Golarion at the time that it disappeared, so most half-orcs now are the result of true-breeding between half-orcs.
- Discussed in the manual for Arcanum. Elves like to believe they were the first race to appear in the world, and most people are uncomfortable with the idea of humans and orcs being related due to Fantastic Racism. However,the author of the chapter on races, John Beddoes, proposes a controversial theory that orcs and elves are both offshoots of humans that have mutated into new races by exposure to magic:
Beddoes: "The premise most difficult to accept is this: two organisms cannot create offspring together unless they are closely related. Although every naturalist and farmer knows it, we are reluctant to accept the same premise when it is applied to ourselves! It is nearly impossible to make the average elf, orc or human accept the truth: the very fact that half-elves and half-orcs exist at all must mean that the parent species are cousins to one another. Further more, the fact that both half-elves and half-orcs are fertile, viable hybrids, rather than sterile sports, means that the relationship between the parent species is very close indeed!"
- The Elder Scrolls: Bretons are a distinct race that resulted from ten generations of elves breeding with their human slaves.
- Them's Fightin' Herds: The longmas of Huoshan are a species of sapient, winged and draconic equines who arose from the interbreeding of (also sapient) horses and dragons. The actual interspecies coupling only appears to have happened once, between the dragon and the stallion known respectively as Honored Mother and Honored Father. All modern-day longmas are the descendants of these two, and all are born from longma parents.
- Star Wars: The Clone Wars: The Dathomirian species is the result of generations of crossbreeding between human women and Zabrak men, eventually resulting in a self-perpetuating hybrid species. They're also a case of Bizarre Sexual Dimorphism and Gender Equals Breed, as the Nightsisters look like extremely pale-skinned humans, while the Nightbrothers look like full-blooded Zabraks.
- Eastern coyotes are the result of cross-breeding between coyotes and grey wolves or domestic dogs, making them larger and more pack-oriented than their western kin and allowing them to move into ecological niches opened by the extirpation of wolves in the eastern states.
- Many species of small wild cats are capable of successfully producing fertile hybrids with one another. This has resulted in the creation of a number of domestic cat breeds created by breeding domestic cats with wild cats of various species and then breeding the hybrids together to obtain varieties of cat with appearances and coat colors housecats don't normally develop. Examples of stably self-perpetuating breeds created in this manner include bengal cats (descend from hybrids of domestic cats and Asian leopard cats), chausies (domestic cat x jungle cat) and savannah cats (domestic cat x serval).
- Though first generation male savannah cats tend to be sterile, requiring the females to be bred with other domestic cats.
- The Clymene dolphin, a species of small dolphin native to large tracts of the tropical and temperate Atlantic ocean, has been determined through genetic testing as having originally arisen through the hybridization of the closely related spinner dolphin and striped dolphin.
- This phenomenon is somewhat more common in birds than in mammals. Both a species of Galapagos finch and one of manakin are known to have arisen in the manner. A more complicated relationship of this sort exists between the pomarine and great skuas: it is known that one originated from the other interbreeding with other skua species, possibly as recently as six or so centuries ago, but exactly which species came first and which arose from self-perpetuating hybrids isn't entirely clear.
