Moral hazard occurs when the presence or promise of a new technology or policy reduces incentives for responsible behaviour, because the consequences of risky behaviour are perceived to be reduced, transferred, or mitigated. Moral hazard risk has been widely empirically investigated in the case of geoengineering for climate change, but other novel technologies have not been subject to such scrutiny. Ever since de-extinction was announced to the public as a viable possibility with modern biotechnology, a series of commentators have (...) argued that the promise of de-extinction will create a moral hazard. The thought is that extinction has been perceived as permanent. Any change in this belief, such as the idea that species can be brought back, potentially undermines the motivation for current conservation efforts. This is an empirical claim that we investigate. Our study assesses the public's support for conservation in scenarios that promise the use of de-extinction to address actions that are likely to cause extinction. We did not find that people were more likely to accept the extinction of a species if its de-extinction was promised in the future. We did, however, find an association between extinction acceptance and judgments that de-extinction could successfully resurrect species. The findings of this study represent a crucial step in assessing the risks novel biotechnology creates. (shrink)

Some people feel distressed reflecting on human extinction. Some people even claim that our efforts and lives would be empty and pointless if humanity becomes extinct, even if this will not occur for millions of years. In this essay, I will attempt to demonstrate that this claim is false. The desire for long-lastingness or quasi-immortality is often unwittingly adopted as a standard for judging whether our efforts are significant. If we accomplish our goals and then later in life conclude (...) that these accomplishments were of no significance, then this is a sign that the desire for long-lastingness has crept into our standards. By recognizing this, and refraining from adopting an unreasonable standard to judge whether our efforts are significant, it will be to our advantage. Then, when we look back on life from an external perspective that encompasses times after humanity has become extinct, we will not conclude that our efforts amounted to nothing. Rather, we will conclude that many people made significant accomplishments that made their lives and the lives of other people better than they would have been if their goals had never been pursued.

Why should we prevent human beings from going extinct? Recently, several theorists have argued for “additional value views,” according to which our reasons to prevent extinction derive both from the value of the welfare of future lives, and from certain additional values relating to the existence of humanity (such as humanity’s intrinsic or “final” value). Even more recently, these theories have come under attack. In this paper, I first offer a partial taxonomy of additional value views, noting the distinction (...) between what I call “outright value views” and “conditional value views.” As I show, recent attacks against additional value views ultimately present problems for outright value views, yet may be avoided entirely by many conditional value views. I illustrate the great variety of possible conditional value views, noting advantages and costs associated with alternative versions. I conclude by sketching a challenge that conditional value views must address, despite their advantages over outright value views. (shrink)

Human extinction is something generally deemed as undesirable, although some scholars view it as a potential solution to the problems of the Earth since it would reduce the moral evil and the suffering that are brought about by humans. We contend that humans collectively have absolute intrinsic value as sentient, conscious and rational entities, and we should preserve them from extinction. However, severe threats, such as climate change and incurable viruses, might push humanity to the brink of (...) class='Hi'>extinction. Should that occur, it might be useful to envision a successor to humans able to preserve and hand down its value. One option would be to resort to humanoid robots that reproduce our salient characteristics by imitation, thanks to AI powered by machine learning. However, the question would arise of how to select the characteristics needed for our successors to thrive. This could prove to be particularly challenging. A way out might come from an algorithm entrusted with this choice. In fact, an algorithmic selection both at the social and at the individual level could be a preferred choice than other traditional ways of making decisions. In this sense, reflecting on human extinction helps us to identify solutions that are also suitable for the problems we face today. (shrink)

This article will explore a problem which is related to our moral obligations towards species. Although the re-creation of extinct animals has been discussed to some degree both in lay deliberations as well as by scientists, advocates tend to emphasize the technological and scientific value of such an endeavour, and the “coolness” factor, 32–33, 2013). This article will provide an argument in favour of re-creation based on normative considerations. The environmentalist community generally accepts that it is wrong to exterminate species, (...) for reasons beyond any instrumental value these species may have. It is often also claimed that humanity has a collective responsibility to either preserve or at least to not exterminate species. These two beliefs are here assumed to be correct. The argument presented here departs from and places these two ideas in a deontological framework, from which it is argued that when humanity causes the extinction of a species, this is a moral transgression, entailing a residual obligation. Such an obligation implies a positive duty to mitigate any harm caused by our moral failure. In light of recent scientific progress in the field of genetic engineering, it will be argued that humanity has a prima facie obligation to re-create species whose extinction mankind may have caused, also known as de-extinction.

This article aims to analyze the perspective of the philosopher Hans Jonas with regard to the rights of animals to life. We will show how, according to Jonas, the ethical significance of animals emerges as they reveal nature’s vulnerability and underscore the moral duty of humans, whose responsibility intensifies as their capacity to cause harm increases. Within this framework, it is essential to recognize that (1) Jonas supports the criterion of maximum benefit when it comes to animal experimentation for scientific (...) purposes; (2) his theory reflects a concern for the conditions of animals within the meat industry, advocating for moderation in consumption; and (3) his ethical approach is particularly focused on the protection of endangered animal species, a concern that has become increasingly urgent with the rise of new powers of technology. For Jonas, an ethical theory that seeks to address the challenge of species preservation must begin with a theoretical redefinition that acknowledges animals as ‘ends in themselves’, a shift that would necessitate a re-evaluation not only of ethics but also of underlying ontological and metaphysical assumptions. Finally, as we will discuss, Jonas’s ongoing debate on the rights of animals to life brings to the forefront the central concern of his ethics of responsibility: maintaining the balance of the cosmic whole against the destructive impact of human activity, which has led to the extinction of animal species with which humans share a ‘solidarity of interests’. It is within this context that Jonas’s stance on animal rights should be understood, and it is precisely here that his position stands out as both innovative and urgent in the defense of animal life.

De-extinction raises anew ontological and epistemological problems that have engaged environmental philosophers for decades. This essay re-examines these issues to provide a fuller understanding—and a critique—of de-extinction. One of my claims is that de-extinction as a philosophical problem merely recycles old issues and debates in the field (hence, “zombie” arguments). De-extinction is a project that arises out of the assertion of human domination of the natural world. Thus the acceptance of de-extinction as an environmental policy (...) is an expression of a human-nature relationship that disvalues the natural world and subjugates nature completely to the interests of humanity.

This book is about the philosophy of de-extinction. CHAPTER 1 introduces the two main philosophical questions that are raised by the prospect of extinct species being brought back from the dead—namely, the ‘Authenticity Question’ and the ‘Ethical Question’. It distinguishes the many different types and methods of de-extinction. Finally, it examines the aims of wildlife conservation with a view to whether they are compatible with de-extinction, or not. CHAPTER 2 examines three prime candidates for de-extinction—namely, the (...) aurochs, the woolly mammoth, and the passenger pigeon. It is about what these animals were like, why people want to resurrect them, and the methods by which their resurrections could be accomplished. CHAPTER 3 is about the authenticity of de-extinct animals. Critics of de-extinction have offered many reasons for thinking that the products of de-extinction will be inauthentic. The bulk of the chapter is taken up with surveying their arguments. We attempt to show that none are convincing, and end the chapter by offering and defending two arguments in favour of the view that authentic de-extinctions are possible. CHAPTER 4 surveys and critically evaluates all the main arguments both for and against de-extinction. It presents a qualified defence of the claim that conservationists should embrace de-extinction. It ends with a list of do’s and don’ts for conservationist de-extinction projects. (shrink)

Qualia Extinction argues that certain experiences depend on social structures for their very possibility — and that when those structures are destroyed, the experiences don’t just become rare. They become impossible. Gone the way a species goes extinct: not elsewhere, not dormant, not awaiting rediscovery, but permanently foreclosed. The book calls this qualia extinction, and it argues that the process conceals itself from those it affects, because the very capacities you would need to recognise the loss are among (...) the capacities that have been lost. This is a work of philosophy. It builds on Habermas, Taylor, MacIntyre, Rorty and Rosa. It develops philosophical concepts — the formatted self, recursive self-occlusion, affective topology — with the precision that philosophical argument demands. It does not offer life hacks or screen time advice. It does not romanticise the past. What it does is name something that has no name. The feeling that something is missing but you cannot say what. The rage that has no adequate object. The grief you cannot mourn because you do not know what you are grieving. The book passes through that grief. It does not end there. It ends with play: the possibility that even within a formatted world, there remain ways of being that are not yet fully captured — absorbed, responsive, alive to what optimisation cannot reach.

Both paleobiology and investigations of ‘major evolutionary transitions’ are intimately concerned with the macroevolutionary shape of life. It is surprising, then, how little studies of major transitions are informed by paleontological perspectives and. I argue that this disconnect is partially justified because paleobiological investigation is typically ‘phenomena-led’, while investigations of major transitions are ‘theory-led’. The distinction turns on evidential relevance: in the former case, evidence is relevant in virtue of its relationship to some phenomena or hypotheses concerning those phenomena; in (...) the latter, evidence is relevant in virtue of providing insights into, or tests of, an abstract body of theory. Because paleobiological data is by-and-large irrelevant to the theory which underwrites the traditional conception of major transitions, it is of limited use to that research program. I suggest that although the traditional conception of major transitions is neither ad-hoc or problematically incomplete, its promise of providing unificatory explanations of the transitions is unlikely to be kept. Further, examining paleobiological investigations of mass extinctions and organogenesis, I further argue that whether or not transitions in paleobiology count as ‘major’ turns on how we conceive of major transitions ; although major transitions potentially have a unified theoretical basis, recent developments suggest that investigations are becoming increasingly phenomena-led; adopting phenomena-led investigations maximizes the evidence available to paleobiologists.

Extinction is usually associated with the death of the last remaining individual of a species, taxon, or population of organisms. Here I ask the question of whether extinction might also be applied to cases where individuals of the relevant category remain alive. Global impacts in the Anthropocene suggest extinction may be broader than typically thought. Technologies available in the emerging ‘synthetic age’ alter taxa in ways that may appropriately be characterized as extinction. The core of the (...) more traditional account of extinction remains valuable. Losing the last few individuals of a taxon matters. But emerging types of loss may demand a broader understanding of extinction. This broader understanding could capture more of what humans are doing to the biosphere. (shrink)

“Existential risks” are risks that threaten the destruction of humanity’s long-term potential: risks of nuclear wars, pandemics, supervolcano eruptions, and so on. On standard utilitarianism, it seems, the reduction of such risks should be a key global priority today. Many effective altruists agree with this verdict. But how should the importance of these risks be assessed on a Christian moral theory? In this paper, I begin to answer this question – taking Thomas Aquinas as a reference, and the risks of (...) anthropogenic extinction as an example. I’ll suggest that on a Thomist framework, driving ourselves extinct would constitute a complete failure to fulfil our God-given nature, a radical form of hubris, and a loss of cosmological significance. So the reduction of such risks seems vital for Thomists, or Christians more broadly. Indeed, I end with the thought that these considerations are not parochially Christian, or indeed specifically religious: everyone with a similar view of mankind – as immensely valuable yet fallen and fragile – should agree that existential risks are a pressing moral concern.

Cet article examine si l’extinction de l’humanité provoquée par une super intelligence artificielle (SIA) aux valeurs divergentes serait néfaste, et pour quelles raisons. La question, selon moi, est faussement complexe. Je commence par présenter les trois principales positions de l’éthique existentielle, c’est-à-dire l’étude des implications éthiques et évaluatives de l’extinction de l’humanité. Il s’agit des points de vue de l’équivalence, des points de vue de la perte future et des points de vue pro-extinctionnistes. Je montre ensuite comment les (...) tenants de chaque point de vue évalueraient un scénario dans lequel l’humanité s’éteindrait à cause de SIA. Bien qu’il y ait des points d’accord, ces trois positions divergent de manière significative, la plupart d’entre elles n’ayant pas été suffisamment explorées dans la littérature philosophique.

The probability of lineal extinction is sensitive to all the moments of the reproductive success probability distribution. In particular, high variance in reproductive success is associated with high probability of lineal extinction. Where male variance in reproductive success exceeds female variance, strictly patrilineal lines of descent will become extinct more rapidly than strictly matrilineal lines of descent. Patrilineal genealogies will be expected to be shallower and broader than matrilineal genealogies under such conditions. Potential implications of this genealogical asymmetry (...) for human descent systems include the greater information content of patrilineal kinship reckoning compared with any other unilineal system and the greater effectiveness of patrilineal kinship as a vehicle for corporate action.

This paper offers a paleobiological perspective on the debate concerning the possible use of biotechnology to bring back extinct species. One lesson from paleobiology is that extinction selectivity matters in addition to extinction rates and extinction magnitude. Combining some of Darwin’s insights about artificial selection with the theory of species selection that paleobiologists developed in the 1970s and 1980s provides a useful context for thinking about de-extinction. Using recent work on the prioritization of candidate species for (...) de-extinction as a test case, the paper argues that de-extinction would be a form of artificial species selection in which humans influence which species persist vs. go extinct. This points to a serious gap in our ethical theory: Much work has been done to clarify the value of biological diversity, but we also need theoretical guidance for decisions that amount to species sorting, and that will shape the macroevolutionary future.

Have we reached what Alexander Galloway dismissively refers to as ‘peak Deleuze’? In this essay, I argue that the arrival at end times – with the sense of mass extinction and philosophy's exhaustion – is indeed a moment of ‘peak Deleuze’, but that this gesture of exhaustion is already implicit in A Thousand Plateaus. Recognising the limits and seduction of a text is never as easy as it seems; every attempt to break up with Deleuze and Guattari, though necessary, (...) is fraught with a whole series of difficulties that were already visible in A Thousand Plateaus's own relation to its outside.

While anthropogenic species extinctions can be considered morally problematic for a range of reasons, they can also be described as a problem of interspecies justice. That is the focus of this paper in which we argue that human-caused species extinctions can be integrated within a non-anthropocentric account of reparative justice that is significantly similar to how reparation is understood within political theory at large. An account such as this faces a series of difficulties, such as how to make right past (...) injustices against victims that do not exist any longer and which belonged to species now extinct. For that purpose, we offer an argument in favour of symbolic forms of reparation in the form of, amongst other things, the preservation and restoration of habitat to materially repair the interspecies justice relationship; as well as monuments and education to honour the nonhuman dead.

In an effort to inform the discussion surrounding existential risks from AI, we formulate Extinction-level Goodhart’s Law as “Virtually any goal specification, pursued to the extreme, will result in the extinction of humanity”, and we aim to understand which formal models are suitable for investigating this hypothesis. Note that we remain agnostic as to whether Extinction-level Goodhart’s Law holds or not. As our key contribution, we identify a set of conditions that are necessary for a model that (...) aims to be informative for evaluating specific arguments for Extinction-level Goodhart’s Law. Since each of the conditions seems to significantly contribute to the complexity of the resulting model, formally evaluating the hypothesis might be exceedingly difficult. This raises the possibility that whether the risk of extinction from artificial intelligence is real or not, the underlying dynamics might be invisible to current scientific methods. (shrink)

In the midst of only the 6th mass extinction in the Earth's history, we must rethink how we teach evolution to prevent natural selection from being incorrectly used as a biological justification for inaction in the face of today's human‐caused mass extinction crisis. Pundits, policy makers, and the general public regularly identify the extinction of endangered species as natural selection at work, rather than attributing modern‐day extinction to the sudden catastrophic bad luck of human caused environmental (...) change, a phenomenon distinct from natural selection. In this natural selection framing, the inability of species to survive in human altered environments is the normal progression of “survival of the fittest” and conservation measures designed to protect species is human interference with natural selection. Paradoxically, this erroneous framing of extinction as the normal course of natural selection ignores humanity's exceptional role in causing today's mass extinction crisis. Our examination of this issue in U.S. college students indicates that it arises from misunderstanding the role of extinction in the history of life, leading us to recommend a greater teaching emphasis on the distinction between extinction and natural selection, and on past mass extinction events.

This review provides an overview of the ethics of extinctions with a focus on the Western analytical environmental ethics literature. It thereby gives special attention to the possible philosophical grounds for Michael Soulé’s assertion that the untimely ‘extinction of populations and species is bad’. Illustrating such debates in environmental ethics, the guiding question for this review concerns why – or when – anthropogenic extinctions are bad or wrong, which also includes the question of when that might not be the (...) case (i.e. which extinctions are even desirable). After providing an explanation of the disciplinary perspective taken (section “Introduction”), the concept of extinction and its history within that literature are introduced (section “Understanding extinction”). Then, in section “Why (or when) might anthropogenic extinctions be morally problematic?”, different reasons for why anthropogenic extinctions might be morally problematic are presented based on the loss of species’ value, harm to nonhuman individuals, the loss of valuable biological variety and duties to future generations. This section concludes by also considering cases where anthropogenic extinctions might be justified. Section “How to respond to extinctions?” then addresses a selection of topics concerning risks and de-extinction technologies. Finally, the section on “Extinction studies” introduces other viewpoints on the ethics of extinction from the extinction studies literature, followed by the “Conclusion”. (shrink)

Many of us think human extinction would be a very bad thing, and that we have moral reasons to prevent it. But there is disagreement over what would make extinction so bad, and thus over what grounds these moral reasons. Recently, several theorists have argued that our reasons to prevent extinction stem not just from the value of the welfare of future lives, but also from certain additional values relating to the existence of humanity itself (for example, (...) humanity’s “final” value, or the value of humanity in itself). In this paper, I argue against these “additional value” views. Despite their initial appeal, these views will inevitably face conflicts between the additional values to which they appeal, and the value of the welfare of future lives. And, I argue, the views cannot plausibly resolve these conflicts. In contrast, these conflicts do not arise for a rival view, on which our reasons to prevent extinction stem just from the value of the welfare of future lives. I conclude that this gives us reason to prefer the latter view, despite the greater initial plausibility of additional value views. (shrink)

A significant proportion of conservationists' work is directed towards efforts to save disappearing species. This relies upon the belief that species extinction is undesirable. When justifications are offered for this belief, they very often rest upon the assumption that extinction brought about by humans is different in kind from other forms of extinction. This paper examines this assumption and reveals that there is indeed good reason to suppose current anthropogenic extinctions to be different in kind from extinctions (...) brought about at other times or by other factors. Having considered – and rejected – quantity and rate of extinction as useful distinguishing factors, four alternative arguments are offered, each identifying a way in which anthropogenic extinction is significantly different from other forms of extinction, even mass extinction: (1) Humans are a different kind of natural cause from other causes of extinction; (2) Extinctions brought about by humans are uniquely persistent; (3) Anthropogenic extinctions are effectively random whereas past mass extinctions are rule-bound; (4) The impact of the current anthropogenic extinction event differs from the impact of other extinction events of the past, such that future recovery may not follow past patterns. Together, these four arguments suggest that the present-day extinction event brought about by humans may be unprecedented and that we cannot clearly extrapolate from past to present recovery from extinctions. Although insufficient as justification for the claim that present-day extinctions are undesirable, the arguments provide some ammunition for conservationists' conviction that species extinction – in which humans play an accelerating role – ought to be prevented.

Developments in genetic engineering may soon allow biologists to clone organisms from extinct species. The process, dubbed “de-extinction,” has been publicized as a means to bring extinct species back to life. For theorists and philosophers of biology, the process also suggests a thought experiment for the ongoing “species problem”: given a species concept, would a clone be classified in the extinct species? Previous analyses have answered this question in the context of specific de-extinction technologies or particular species concepts. (...) The thought experiment is given more comprehensive treatment here. Given the products of three de-extinction technologies, twenty-two species concepts are “tested” to see which are consistent with the idea that species may be resurrected. The ensuing discussion considers whether or not de-extinction is a conceptually coherent research program and, if so, whether or not its development may contribute to a resolution of the species problem. Ultimately, theorists must face a choice: they may revise their commitments to species concepts or they may recognize de-extinction as a means to make progress in the species problem. (shrink)

Finally, we call for empirical research into (...) how the possibility of the technology affects our behaviour or our character to help the debate transcend duelling intuitions. (shrink)

The paper explores the contact between the literary notion of the end of the world as depicted in H.G. Wells’s science fiction novel _The Time Machine_ and the concept of extinction, in the sense developed by the French naturalist Georges Cuvier, who at the turn of the 19 th century formulated a thesis about the structure of the world with a built-in end. The time traveller in Wells’s novel is driven into the distant future by an obsessive desire to (...) know the fate of the world. He encounters it on the shores of an already dead sea, where he is greeted by the image of a dying world, unmoving in the dull red light of a never-setting sun. Cuvier, on the other hand, encounters the end of the world as a reader of traces of history as told by nature through its layering and piling up. Within these layers, Cuvier recognises moments of repetitive interruptions that have left behind not only whole species and genera, but also entire worlds in the great natural history. The key question, then, is the status of the end within the proposed mechanism of return and repetition. (shrink)

The theme of human extinction is increasingly at the center of the current debate on moral philosophy and bioethics. We look at space missions and station construction projects capable of accommodating a large population and at the colonization of other planets with great hope. However, solutions are not excluded either, which for now certainly appear to be much more original. One of the most original projects involves launching a spacecraft containing cryopreserved human embryos, which, once they arrive at destination (...) on another planet, must be thawed and birthed by intelligent machines through artificial wombs (ectogenesis). In this paper, I do not intend to analyze whether the embryo space colonization project is indeed feasible. Instead, I will focus on examining the primary moral questions raised by the embryo space colonization project to determine whether, at least prima facie, it can be deemed morally acceptable. I will begin by discussing the objection advanced by Konrad Szocik (2021), according to which any embryo space colonization project is doomed to failure because it cannot offer the hoped-for solution to the problem of the extinction of the human species (second paragraph). In the third paragraph, then, I will ask whether embryo space colonization is able to ensure the people it brings into the world an adequate or at least the morally appropriate quality of life. Finally, in the fourth and last paragraph, I will examine the question of the morality of human reproduction that passes through the guidance and choice of intelligent machines. I will argue that to evaluate the morality of this project we should consider not only the interests and quality of life of the first people who could be born but also the interests of all possible subsequent generations.

Longtermism is the view that the most urgent global priorities, and those to which we should devote the largest portion of our resources, are those that focus on (i) ensuring a long future for humanity, and perhaps sentient or intelligent life more generally, and (ii) improving the quality of the lives that inhabit that long future. While it is by no means the only one, the argument most commonly given for this conclusion is that these interventions have greater expected goodness (...) per unit of resource devoted to them than each of the other available interventions, including those that focus on the health and well-being of the current population. In this paper, I argue that, even if we grant the consequentialist ethics upon which this argument depends, and even if we grant one of the axiologies that are typically paired with that ethics to give the argument, we are not morally required to choose an option that maximises expected utility; indeed, we might not even be permitted to do so. Instead, I will argue, if the argument's consequentialism is correct, we should choose using a decision theory that is sensitive to risk, and allows us to give greater weight to worse-case outcomes than expected utility theory does. And, I will show, such decision theories do not always recommend longtermist interventions. Indeed, sometimes, they recommend exactly the opposite: sometimes, they recommend hastening human extinction. Many, though not all, will take this as a reductio of the consequentialism or the axiology of the argument. I remain agnostic on the conclusion we should draw. (shrink)

Extinction is a concept of rapidly growing importance, with the world currently in the sixth mass extinction event and a biodiversity crisis. However, the concept of extinction has itself received surprisingly little attention from philosophers. I will first argue that in practice there is no single unified concept of extinction, but instead that its usage divides between descriptive, epistemic, and declarative concepts. I will then consider the epistemic challenges that arise in ascertaining whether a species has (...) gone extinct, and how these lead to serious limitations on responsibility and accountability for preventing extinctions. I will propose two conceptual engineering changes to our understanding of extinction. Firstly, to use twin epistemic concepts of extinction, corresponding to high and low epistemic demands. Secondly, to explicitly recognize that in many contexts extinction is a thick concept that contains an evaluative component, which therefore motivates explicit ethical considerations such as the use of precautionary principles.

radical politics today should not be concerned with merely averting the worst, but rather with beginning again at the end.

This book defends an account of justice to nonhuman beings – i.e., to animals, plants etc. – also known as ecological or interspecies justice, and which lies in the intersection of environmental political theory and environmental ethics. More specifically, against the background of the current extinction crisis this book defends a global non-ranking biocentric theory of distributive ecological/interspecies justice to wild nonhuman beings, because the extinction crisis does not only need practical solutions, but also an account of how (...) it is the outcome of large-scale injustice. This book not only provides a novel theoretical framework that supports such a claim, but it also develops the theoretical tools to find just compromises between the entitlements of intraspecies and intra-human global distributive justice to ecological space for the purpose of working towards a vision of just conservation. -/- Content: 1.

On certain plausible views, if humanity were to unanimously decide to cause its own extinction, this would not be wrong, since there is no one whom this act would wrong. We argue this is incorrect. Causing human extinction would still wrong someone; namely, our forebears who sacrificed life, limb and livelihood for the good of posterity, and whose sacrifices would be made less morally worthwhile by this heinous act.

Extinction deeply colors the way we think about conservation and the role of humans in nature. It is easy to overlook how recently, in fact, it has entered our consciousness. Only in the last two centuries has science sought to critically study life's origins, development, and diversification. Only in the last several generations have we identified and calibrated life's five major extinction events and speculated on their causes and effects. And only in recent decades have we come to (...) appreciate the still‐unfolding fate of life's diversity under the increasing influence of humanity. The story of extinction has continually changed as this monumental process of interdisciplinary synthesis and imagination has unfolded. Geology, paleontology, taxonomy, biogeography, and evolutionary biology have allowed us to comprehend the deep temporal and broad spatial dynamics of the extinction story. Archaeology, cultural anthropology, and environmental and economic history have illuminated the role of humans in altering the trajectory of species, landscapes, and ecosystems over the millennia. Ecology, genetics, population biology, and conservation biology have revealed the more recent patterns in life's vulnerability and resilience. As a phenomenon, extinction is as old as life itself. As a story shaping our consciousness, values, and intentions, it is still new. And it is uncomfortable. (shrink)

A number of influential biologists are currently pursuing efforts to restore previously extinct species. But for decades, philosophers of biology have regarded “de-extinction” as conceptually incoherent. Once a species is gone, it is gone forever. We argue that a range of metaphysical, biological, and ethical grounds for opposing de-extinction are at best inconclusive and that a pragmatic stance that allows for its possibility is more appealing.

In this paper, we discuss the following four alternative ways of understanding the outcomes of resurrection biology. Implications of each of the ways are discussed with respect to concepts of species and extinction. Replication: animals created by resurrection biology do not belong to the original species but are copies of it. The view is compatible with finality of extinction as well as with certain biological and ecological species concepts. Re-creation: animals created are members of the original species but, (...) despite their existence, the species remains extinct. The view is incompatible with all species concepts presented. Non-extinction: animals produced belong to the original species which actually never went extinct. The view may be consistent with phenetic and phylogenetic species concepts as well as with finality of extinction. According to literal resurrection, resurrection biology is successful in reversing extinction through the creation of new members of species that once went extinct. This view presupposes non-finality of extinction and it is compatible with phenetic species concepts. It is notable that no species or extinction concept is consistent with all possible views of resurrection biology nor is any view of resurrection biology consistent with all species or extinction concepts. Thus, one’s views regarding species and extinction determine which views one can adopt regarding resurrection biology and vice versa. (shrink)

“de-extinction” refers to the process of resurrecting extinct species by genetic methods. This science-fiction-sounding idea is in fact already in early processes of scientific implementation. Although this recent “revival of the dead” raises deep ethical questions, the ethics of de-extinction has barely received philosophical treatment. Rather than seeking a verdict for or against de-extinction, this paper attempts an overview and some novel analyses of the main ethical considerations. Five dimensions of the ethics of de-extinction are explored: (...) (a) the possible contribution of de-extinction to promoting ecological values, (b) the deontological argument that we owe de-extinction to species we rendered extinct, (c) the question of “playing God” through de-extinction, (d) the utilitarian perspective, and (e) the role of aesthetic considerations in the ethics of de-extinction. A general feature arising from the paper’s discussion is that, due to de-extinction’s special character, it repeatedly tests the limits of our ethical notions. (shrink)

In this article I make two main critiques of Kaczmarek and Beard's article ‘Human Extinction and Our Obligations to the Past’. First, I argue that there is an ambiguity in what it means to realise the benefits of a sacrifice and that this ambiguity affects the persuasiveness of the authors’ arguments and responses to various objections to their view. Second, I argue that their core argument against human extinction depends on an unsupported assumption about the existence and importance (...) of existential benefits. (shrink)

The cumulative impact of enhancement technologies may alter the human species in the very long-term future. In this article, I will start showing how radical genetic enhancements may accelerate the conversion into a novel species. I will also clarify the concepts of ‘biological species’, ‘transhuman’ and ‘posthuman’. Then, I will summarize some ethical arguments for creating a transhuman or posthuman species with a substantially higher level of well-being than the human one. In particular, I will present what I shall call (...) the Principle of the Best Interests of Posthumanity, which states that the enhancement of the human and transhuman species must be directed towards the creation of a posthuman existence that is substantially more valuable than its predecessors. I suggest that human extinction may be considered, within that principle, as one of the best interests of posthumanity. Finally, I will develop three objections that make that principle unattractive and that show that pursuing a full-blown programme of posthuman evolution is ethically flawed. (shrink)

The thylacine was a shy and elusive nonhuman animal who survived in small numbers on the island of Tasmania, Australia, when European settlers arrived in 1803. After a deliberate campaign of eradication, the species disappeared 130 years later. Visual and verbal constructions in the nineteenth century labeled the thylacine a ferocious predator, but photographs of individuals in British and American zoos that were used to illustrate early twentieth-century zoological works presented a very different impression of the animal. The publication of (...) these photographs, however, had little effect on the relentless progress of extermination. This essay focuses on the relationship between photographs of thylacines and the process of extinction, between images and words, and between pictures of dead animals and live ones. The procedures, claims, and limitations of photography are crucial to the messages generated by these images and to the role they played in the representation of the species. This essay explains why the medium of photography and pleas for preservation could not save the thylacine. (shrink)

The history of life on Earth has been shaken in the last half billion years by five mass extinctions that have killed at least three-quarters of biodiversity in a geologically short time. These five extinctions were due to major ecological upheavals, with endogenous or exogenous drivers (volcanic eruptions, impact of asteroids, etc.). Today, many data show that the current extinction rate is comparable to or even worse than that of the Big Five mass extinctions of the past. The difference (...) is that this time the asteroid is one species: Homo sapiens. There are good reasons to include the Sixth Mass Extinction in the definition of the Anthropocene. This drastic reduction in biodiversity will leave an irreversible geological and paleontological mark. It interacts with climate change, with a multiplicative effect. It contributes to the environmental crisis that reduces ecosystem services and threatens human health (i.e., likelihood of spillovers). (shrink)

T. J. Kasperbauer presents an analysis of the ethics of de-extinction that is fairly distinctive in its focus on the welfare of individual animals. But while he is right to express concerns about individual animal well-being, individualism may not be the most important lens through which to view this issue. If one examines more closely what is at issue in de-extinction technologies in relation to species, additional problems appear that cast doubt both on the legitimacy of de-extinction (...) projects, and on the limited defense of them that Kasperbauer offers.

Extinction learning although initially successful in blocking fear responses, can result in relapse in some individuals over time. This deficit demands a strategy that could reinforce the extinction of fear. The current study aimed to investigate the top-down regulatory processes like cognitive reappraisal and the nature of reappraisal on augmentation of fear extinction and retention. We used a screaming lady fear conditioning paradigm with 63 participants (M = 43, F = 20; Mean (SD) age = 20.6 (1.40) (...) years) and subjective fear, valence, expectancy ratings and skin conductance response (SCR) as outcome measures. The participants were randomly assigned into three groups: creative reappraisal, ordinary reappraisal and standard extinction groups and completed acquisition (day 1), extinction (day 2) and extinction-retest (day 3) phases. Our results indicate that cognitive reappraisal aimed at reducing the aversiveness of the UCS does not disrupt prediction error during extinction. Our results did not indicate any enhanced effect of cognitive reappraisal on subjective and physiological measures of conditioned fear responses during extinction. Our findings highlight the gap between the implementation of cognitive reappraisal and successful affective outcomes. Effective cognitive reappraisal requires careful consideration of factors like cognitive effort, situation intensity, reappraisal affordance, implementation cost and appraisals associated with fear. Interventions aimed at enhancing extinction through cognitive reappraisal should consider these factors for the effective implementation of cognitive reappraisal. (shrink)

Contesting Extinctions: Decolonial and Regenerative Futures critically interrogates the discursive framing of extinctions and how they relate to the systems that bring about biocultural loss. The chapters in this multidisciplinary volume examine approaches to ecological and social extinction and resurgence from a variety of fields, including environmental studies, literary studies, political science, and philosophy. Grounding their scholarship in decolonial, Indigenous, and counter-hegemonic frameworks, the contributors advocate for shifting the discursive focus from ruin to regeneration. -/- .

In a laboratory on a university campus in Santa Cruz, California, Ben Novak is doing everything he can to bring Ectopistes migratorius back from the dead. Using techniques now available in genome reading and gene synthesis, he and paleogenomicist Beth Shapiro hope that, by 2032, a flock of passenger pigeons ten thousand or more strong will have resumed an ecologically significant role in the mast forests of the Eastern United States. Novak knows—and the International Union for Conservation of Nature (IUCN) (...) affirms—that the challenges involved in making de‐extinction work are far from solely genetic. Novak is doing an ecological risk assessment of passenger pigeon reintroduction to figure out whether flocks of the resurrected species would pose any special hazards to ecosystems. Ecological harm is one of several worries attending the prospect of de‐extinction. Among other concerns are the possible harm that individuals born through this process might suffer and the possible introduction of disease vectors. But I want to step back from these immediate questions and think about some conceptual ones that operate in the background. Technology can be a grand shaper of cultural norms and expectations, and de‐extinction should be looked at in relation to a number of emerging technologies. This paper will examine the degree to which de‐extinction is part of a more widespread restructuring of ethical relationships to the surrounding world that are under way at the hands of emerging technologies. This restructuring is part of an ongoing shift in how to think about conservation in the new epoch of the Anthropocene. (shrink)

Humans are the only species that can both cause and contemplate their own extinction. An essay revise of Todd May’s thoughtful book 'Should We Go Extinct?'.

“De-extinction” projects propose to re-create or “resurrect” extinct species. Perhaps the most common justification offered for these projects is that humans have an obligation to make restitution to species we have eradicated. There are three versions of this argument for de-extinction—one individualistic, one concerned with species, and one that emphasizes ecological restoration—and all three fail to provide a compelling case for species revival. A general critique of de-extinction can be sketched that highlights how it can both facilitate (...) inattentiveness to biological and ecological boundaries and foster a managerial mentality toward the natural world.
