De-Extinction Is Redefining What It Means to Be Alive

Summary
What This Article Is About
Sadiah Qureshi, a historian of science at the University of Manchester and author of Vanished: An Unnatural History of Extinction (2025), argues that de-extinction technologies are not merely a scientific curiosity but a philosophically transformative force already reshaping what we mean by life, death, and extinction. Using the case of the Pyrenean ibex — the first species to go extinct twice, including a cloned individual that died within minutes of birth in 2003 — Qureshi introduces a new framework advanced by some scientists: that a species preserved in cryopreservation is not extinct, but merely “evolutionarily torpid.” This redefinition, she argues, is far from semantic — it has profound consequences for conservation ethics, resource allocation, and humanity’s moral obligations to the living world.
Tracing the history of freezing technologies from Christopher Polge’s 1949 breakthrough in cryogenics through Kurt Benirschke’s 1975 Frozen Zoo at San Diego to the 2025 IUCN World Conservation Congress vote on genetically modified organisms, Qureshi maps how de-extinction has moved from speculative science to active policy. She critically examines organisations like Revive and Restore, the Colossal Biosciences “dire wolf,” and Ben Novak’s passenger pigeon project, ultimately warning that treating species as disembodied genetic lineages risks eroding the urgency to protect living beings. Her conclusion is both ecological and ethical: the biodiversity crisis demands better relationships with living animals as kin — not bioengineered substitutes designed to satisfy human guilt.
Key Points
Main Takeaways
Extinction Is Being Redefined
De-extinction advocates argue that species with cryopreserved cells are not truly extinct but “evolutionarily torpid” — a redefinition with enormous implications for conservation policy.
De-Extinction Is Now Policy
The 2025 IUCN World Conservation Congress in Abu Dhabi established the first policy on synthetic biology, moving de-extinction from theoretical debate into regulatory reality.
Revived Species Are Not Original
The peregrine falcon “restored” in the 1970s was genetically a hybrid of subspecies — functionally similar but not identical, raising questions about what revival actually means.
Philanthropy Shapes Conservation
De-extinction is largely funded by private donors, raising uncomfortable questions about whether exceptional wealth gives disproportionate power over which species receive a second chance.
Cryopreservation Began in 1949
The science of freezing biological tissue without damage was discovered serendipitously by Polge, Smith, and Parkes, laying the foundation for today’s frozen zoos and de-extinction projects.
Species Are More Than Genomes
Qureshi argues that reducing life to genetic information ignores the cultural, ecological, and experiential dimensions of being alive — a dodo revived in a lab cannot learn to be a dodo.

Article Analysis
Breaking Down the Elements
Main Idea
De-Extinction Is Already Changing What Life and Death Mean
Qureshi’s central argument is that de-extinction technologies are not a future hypothetical but a present philosophical crisis. By redefining extinction as reversible — or even as never having occurred — these technologies quietly erode the moral urgency that has historically driven conservation. The biodiversity crisis, she contends, cannot be solved by bioengineering new surrogates; it requires confronting humanity’s destructive relationship with living beings.
Purpose
To Expose the Hidden Philosophy Driving De-Extinction
Qureshi writes to challenge readers — scientists, policymakers, and the public — to look beyond the spectacle of revived mammoths and dire wolves and examine the underlying assumptions: that species are reducible to genomes, that technology can substitute for ecological accountability, and that human authority over other species is a given rather than an entitlement to be interrogated.
Structure
Case Study → Historical Genealogy → Ethical Critique → Moral Call
The essay opens with the visceral case of the Pyrenean ibex to hook the reader philosophically, then traces the history of cryogenics from 1949 to ground the argument in science, before pivoting to a sustained ethical critique of de-extinction’s redefinitions. It concludes with a moral call to action — not technological, but relational. The structure is Narrative → Historical → Critical → Normative.
Tone
Measured, Scholarly & Morally Urgent
Qureshi’s tone is intellectually scrupulous — she presents de-extinction’s proponents fairly before dismantling their assumptions. Yet the essay builds to an unmistakable moral urgency, particularly in its closing passages where the dodo metaphor crystallises her point: technology cannot transmit lived experience. The register is that of a historian who has earned the right to make a philosophical argument, not a polemicist.

Occurring or discovered by happy accident rather than deliberate design; used here to describe how the technique of freezing tissue without damage was stumbled upon.
“However, their serendipitous finding paved the way for the new science of cryogenics.”
To make an unpleasant feeling, such as guilt or anxiety, less intense; to soothe or relieve a distressing emotional or moral burden.
“…if genetic material assuages our guilt that a ‘way of being’ survives, why invest in protecting living animals?”
Intended to stimulate strong reactions, thought, or debate; deliberately challenging accepted assumptions in order to force re-examination.
“But there is also a more provocative telling: that neither happened, because the bucardo never went extinct in the first place.”
Deserving praise or commendation; used here with irony to acknowledge that de-extinction may be well-intentioned while still critiquing its underlying assumptions.
“Instead of perpetuating human supremacy, even with the most laudable of motives, we can still choose a different future.”
A reduction in the significance, quality, or completeness of something; here used to describe extinction as an irreversible impoverishment of life on Earth.
“Until recently, species loss was a permanent diminishment of life on Earth.”
Larger or more significant than is fair or expected in relation to something else; used here to critique the outsized influence of wealthy donors over conservation decisions.
“…exceptional wealth gives some people disproportionate power in deciding which species are chosen for a second chance.”

FAQ
Frequently Asked Questions
The Pyrenean ibex, or bucardo, was a mountain goat native to Spain that became extinct in 2000 when its last individual, Celia, died. In 2003, scientists used tissue from Celia to create a clone that was born alive but died within minutes due to a defective lung — making the bucardo arguably the first species to go extinct twice. Qureshi uses this case because it immediately forces the reader to confront the philosophical and biological ambiguities at the heart of de-extinction.
Revive and Restore is a de-extinction organisation co-founded in 2012 by Stewart Brand and Ryan Phelan, originally an offshoot of the Long Now Foundation in San Francisco. The article notes it has openly sought to reshape humanity’s relationship with nature and extinction, and that its scientist Ben Novak is working to bring back the passenger pigeon. Qureshi uses it to illustrate how de-extinction is as much a philosophical and future-building project as a scientific one.
Qureshi references Epstein — who facilitated donors to biological research even after his 2008 conviction — to illustrate a broader concern about the ethics of philanthropic funding in science. Her point is not that de-extinction is tainted by Epstein specifically, but that the field’s reliance on elite private donors raises a structural question: should exceptional wealth give individuals disproportionate power in deciding which species receive a second chance, shaping not just the present but all future life on Earth?

Our Ultimate Reading Course offers 365 articles with 2,400+ questions to systematically improve your reading comprehension skills.
This article is rated Advanced. It demands simultaneous engagement across biology, philosophy of science, ethics, and history — requiring the reader to track a layered argument spanning from 1949 cryogenics through to the 2025 IUCN Congress. The essay’s most demanding moments are inferential: Qureshi frequently implies her philosophical position rather than stating it outright, and the dodo metaphor in the closing section requires readers to interpret a literary image within an ethical framework rather than take it literally.
Sadiah Qureshi is Chair of Modern British History at the University of Manchester and author of Vanished: An Unnatural History of Extinction (2025). Her significance lies in her disciplinary crossing: she brings a historian of science, race, and empire to a conversation usually dominated by biologists and biotech advocates. This allows her to contextualise de-extinction within longer patterns of human authority over nature and to interrogate the power structures — philanthropic, colonial, and technological — that determine whose vision of the future gets built.
