Dire wolf 'de-extinction' promotes false hope

Technology can't undo extinction, argue Professor Peter Banks and Professor Dieter Hochuli.

Over the past week, the media have been inundated with news of the 鈥渄e-extinction鈥� of the dire wolf (Aenocyon dirus) 鈥� a species that went extinct聽.

The breakthrough has been achieved by聽, a multibillion-dollar United States company that claims their goal is to restore biodiversity through the de-extinction of species.

The project is聽聽as a conservation win. But does this technology really have the best interests of conservation in mind?

We argue as ecologists that genetic advancements like these, while they are major scientific and technological feats, still risk minimising the severity of the current extinction crisis.

Importantly, they take away focus from proven conservation efforts that are needed to protect the biodiversity that remains.

High-tech copies of wolves

First, it is important to recognise that Romulus, Remus and Khaleesi, the three 鈥渄ire wolf鈥� pups created, are not聽actually聽dire wolves.

Colossal carried out聽聽of the grey wolf genome to create their 鈥渄ire wolves鈥� using a genetic technique called CRISPR-Cas9.

The grey wolf鈥檚 genome is聽聽long. Would we consider a chimpanzee, with which we share 98.8% of our genome, to be human after 20 edits?

The reality is that these are three slightly modified grey wolves.

This de-extinction project has had millions of dollars poured into it 鈥� amounts of money most conservation programs could only dream of. There are聽: habitat protection and restoration, the control of invasive species and the phasing out of fossil fuels.

However, these solutions are not slickly marketed as shiny, techno-fix packages like de-extinction. Instead, they are聽.

Extinction is irreversible

Promoting extinction as reversible risks downplaying its gravity and legacy.

Headlines like the one that appeared on the front cover of聽聽鈥� with the word 鈥渆xtinct鈥� crossed out 鈥� seed a false hope that no matter what environmental damage is done, species loss can be easily undone.

The risk is that de-extinction will be used as an ultimate offset for any聽.

. It is possibly our most primal instinct. We mourn and feel great sadness for the death of an individual, not only because they are gone, but because it is irreversible and final. Permanent.

That finality is the same for humans or any living animal. It is what makes fighting biodiversity loss such an urgent concern, so much so that people risk their lives to prevent it, with聽聽in their fight to protect endangered species.

In the conservation movement,听聽鈥� like the northern white rhino and the passenger pigeon 鈥� helps underline the argument in favour of protecting current species. Framing extinction as temporary creates false hope and undermines motivation for real conservation action.

We might already be seeing this happen in response to the 鈥渄e-extinction鈥� of the dire wolf. Interior Secretary of the Trump administration, Doug Burgum, praised the new biotechnology advancement and used it as an argument for the removal of the US聽.

What good is bringing back species if there are no protective laws to address the drivers of their declines?

Could we protect the dire wolf even if it did come back?

It is deeply ironic that while millions are being spent recreating a dire wolf proxy, its cousin, the grey wolf, is聽. Just last month,听聽to overturn the legal protection that prevented wolves from being hunted north of the Duero River.

Other predators are affected, too. In Australia, the dingo, which has been shown to suppress invasive cats and聽,听, is also heavily persecuted 鈥� just like the聽, which Colossal聽.

If we can鈥檛 safeguard or protect habitat for apex predators today, in ecosystems that are already under immense pressure, what kind of world would we be bringing extinct species back into? Up to聽聽are considered to go extinct every day. No amount of genetic tech will solve this unless we address the root causes: habitat destruction, over-exploitation and climate change.

The de-extinction of the dire wolf may sound like a conservation breakthrough, but it risks distracting us from the protection of our current living species. This approach turns biodiversity conservation into a billionaire鈥檚 Jurassic Park fantasy instead of addressing the crisis we already know how to fix.
