List of resurrected species

This is a list of resurrected species. So far, there is no scientifically verified method of DNA resurrection of a previously extinct species.

## Cloning

[edit]

### Pyrenean Ibex

[edit]

Further information: Pyrenean ibex

The Pyrenean ibex (Capra pyrenaica pyrenaica) is an Iberian ibex subspecies with the unfortunate moniker of the first animal to go extinct twice. Endemic to the Pyrenees and Cantabrian Mountains, this ibex was driven to extinction due to competition with livestock and introduced wild ungulates. Several attempts were made to clone the Pyrenean ibex, and one individual was born to a domestic goat mother in 2003. However, this newborn died within minutes due to a lung defect.[1]

## Seed germination

[edit]

### Judean date palm

[edit]

Further information: Judean date palm

The Judean date palm is a cultivar of the date palm (Phoenix dactylifera) that is historically endemic to ancient Judea (modern-day Israel and Palestine). It is genetically unique, and closely related to modern Iraqi and Moroccan varieties.[2] Between 1963 and 1991, archaeologists discovered Judean date seeds in excavation sites. Through radiocarbon dating, they were determined to be between 1,900 and 2,300 years old. In 2008, researchers at the Arava Institute for Environmental Studies began to germinate the seeds.[2]

As of 2023[update], 7 Judean date palms have successfully germinated. In 2020, researchers began to harvest dates from these trees. Experiments to revive this cultivar are ongoing.[3]

## Thawing

[edit]

* Pithovirus sibericum: 30,000 year old giant virus[4]
* Panagrolaimus kolymaensis: This novel species of nematode was resurrected from cryptobiosis in 2023. The nematodes had been frozen in the Siberian permafrost since the Pleistocene, approximately 46,000 years ago.[5]
