Three years after the death the last Pyrenean ibex, Celia, a clone of her is born only to subsequently die from lung defects. Within minutes, the Pyrenean ibex becomes the first and so-far only species to have ever gone de-extinct as well as go extinct twice.

The Pyrenean ibex, Aragonese and Spanish common name bucardo, Basque common name bukardo, Catalan common name herc and French common name bouquetin, was one of the four subspecies of the Iberian ibex or Iberian wild goat, a species native to the Iberian Peninsula and immediately adjacent southern France. The Pyrenean ibex occurred in the northeastern part of the species' range in the Cantabrian Mountains and the Pyrenees, in northern Spain and the far south of France. This subspecies was common during the Holocene and Upper Pleistocene, during which their morphology, primarily some skulls, of the Pyrenean ibex evolved to be larger than other subspecies of Capra pyrenaica in southwestern Europe from the same time.

Cloning is the process of producing individual organisms with identical genomes, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction; this reproduction of an organism by itself without a mate is known as parthenogenesis. In the field of biotechnology, cloning is the process of creating cloned organisms of cells and of DNA fragments.

De-extinction is the process of generating an organism that either resembles or is an extinct organism. There are several ways to carry out the process of de-extinction. Cloning is the most widely proposed method, although genome editing and selective breeding have also been considered. Similar techniques have been applied to certain endangered species, in hopes to boost their genetic diversity. The only method of the three that would provide an animal with the same genetic identity is cloning. There are benefits and drawbacks to the process of de-extinction ranging from technological advancements to ethical issues.
