* It's now believed that Neanderthals didn't go extinct due to being driven out by the more "advanced" Homo sapiens (although intertribal violence doubtless happened), but rather that they interbred until there wasn't a meaningful distinction between either subspecies of human anymore.

* 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 by breeding housecats 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 [[https://en.wikipedia.org/wiki/Bengal_cat Bengal cats]] (descend from hybrids of domestic cats and Asian leopard cats), [[https://en.wikipedia.org/wiki/Chausie chausies]] (domestic cat x jungle cat) and [[https://en.wikipedia.org/wiki/Savannah_cat savannah cats]] (domestic cat x serval), although first generation male savannah cats tend to be sterile, requiring the females to be bred with other domestic cats.

More negatively, there are fears that the Scottish wildcat could become effectively extinct due to hybridization with domestic cats.

* ''Literature/KittyCatKillSat'': Lily discovers that two of her employees are in a relationship and want a child, but are depressed because they can't have one of their own. Lily decides to fire up the gene splicer and merge their DNA samples into a new hybrid species that is not only viable on its own but can breed with either of the parent species. One of the Lily's other employees, shocked, says she ''thought'' the problem was that [[HomosexualReproduction they're both male]]. Lily scoffs; at the tech level she's operating at, that problem literally wasn't even worth mentioning.
