Pyrenean Ibex Mountain Goat: The First and Only Animal in the World to Go Extinct Twice


In the annals of history, the tale of the Pyrenean ibex (Capra pyrenaica pyrenaica) stands as a somber reminder of the fragility of our planet’s biodiversity. This mountain-dwelling goat, native to the Pyrenees mountain range between France and Spain, has etched its name in the record books as the first and only animal to have gone extinct twice. The remarkable journey of the Pyrenean ibex from the brink of extinction to a fleeting resurrection and back to oblivion is a poignant lesson that highlights the pressing need for conservation efforts in safeguarding endangered species worldwide.

Origins and Decline

The Pyrenean ibex, also known as the bucardo or Spanish ibex, once roamed freely across the Pyrenees, an ancient mountain chain adorned with lush meadows and rocky cliffs. These herbivorous animals were adapted to the harsh alpine climate and were known for their nimble movements on treacherous terrain. However, like many other species, human activities played a significant role in their decline.

Hunting and habitat destruction were the primary culprits behind the Pyrenean ibex’s dwindling numbers. Over the centuries, the population was relentlessly hunted for their meat, hides, and valuable horns. Simultaneously, deforestation and land development diminished their natural habitats, leaving them with limited areas to thrive.

First Extinction

By the early 20th century, the Pyrenean ibex population had plummeted to alarming levels, and conservationists sounded the alarm. Despite efforts to protect and revive the species, the last known wild Pyrenean ibex was reported in 2000. This moment marked the tragic first extinction of the species. With the species declared extinct, the world mourned the loss of another unique creature, reminding us of the consequences of our actions on the environment.

The Lazarus Project

However, in a surprising twist of fate, the story of the Pyrenean ibex was not yet over. Scientists decided to embark on an ambitious endeavor called “The Lazarus Project,” an attempt to bring the extinct ibex back to life through cloning.

In 2003, using advanced reproductive techniques, scientists collected DNA samples from the last female Pyrenean ibex before her death. The nucleus of one of her cells was then implanted into the egg of a domestic goat, creating a hybrid embryo. This embryo was then placed into the womb of a surrogate goat. After several attempts, a healthy female Pyrenean ibex named “Celia” was born on January 30, 2009. It was a moment of great hope, as Celia represented the first time an extinct animal had been successfully cloned.

Short-Lived Resurrection

Celia’s birth was a moment of triumph and an example of the extraordinary advances in science and conservation. However, the celebration was short-lived. Tragically, just seven minutes after her birth, she succumbed to a lung defect, highlighting the difficulties of cloning and the challenges associated with resurrecting a species from extinction.

The Second Extinction

With the passing of Celia, the Pyrenean ibex was, once again, declared extinct. The species that had briefly tasted the prospect of survival had slipped through humanity’s grasp for the second time. The Lazarus Project had underscored the limitations of cloning and the complexity of ecological restoration, while also igniting ethical debates surrounding the concept of resurrecting extinct species.


The story of the Pyrenean ibex mountain goat is a poignant reminder of the consequences of human activities on the delicate balance of nature. The extinction of the Pyrenean ibex twice stands as a testament to the irreversible damage we can inflict upon the natural world. While scientific advancements like “The Lazarus Project” offer hope for the future, they also remind us of the complexities and limitations of conservation efforts.

As we continue to grapple with the implications of extinction and the fragility of biodiversity, the tale of the Pyrenean ibex serves as a rallying cry for increased conservation initiatives and a profound appreciation for the diversity of life on Earth. The lesson learned from the rise and fall of this remarkable species should inspire us to protect and preserve all living beings that share our planet, ensuring that no creature ever goes extinct for the third time.
