Comparative thanatologists Footnote 2 have uncovered two main ways in which animals respond to death. We use this term, following Henrich et al. We take anthropocentrism to be something distinct from anthropomorphism. Skelhorn, J. Adachi, I.

Comparative qnd study the what is variable coding to the dead and the dying in nonhuman animals. Despite the wide variety of thanatological behaviours that have been documented in several different species, comparative thanatologists assume that the concept of death CoD is very difficult to acquire and will be boht rare cognitive feat once we move past the human species.

In this paper, we argue that this assumption is based on two forms presator anthropocentrism: bs an intellectual anthropocentrism, which leads sxample an over-intellectualisation of the CoD, and 2 an emotional anthropocentrism, which yields an excessive focus on grief as a reaction to death. Contrary to what these two forms of anthropocentrism suggest, we argue that the CoD requires relatively little cognitive complexity and that it can emerge independently from mourning behaviour.

Moreover, if we turn towards the natural predatorr, we can see that the minimal cognitive requirements for a CoD are in fact met by many nonhuman species and there are multiple learning pathways and opportunities for animals in the wild to develop a CoD. This allows us to conclude that the CoD will be relatively easy to acquire and, so, we can expect it to be fairly common in nature. Comparative thanatologists attempt to uncover the proximate mechanisms involved in the responses to the dead and the dying across animal Footnote 1 species, as well as the ultimate functions behind these mechanisms.

This area of study is filled with difficulties, given that ethical constraints make the use of experiments particularly tricky Gonçalves and Biro ; Monsóand so scientists must rely more than usual on opportunistic exampls gathered in the wild. For instance, despite the growing number of thanatological reports gathered on monkeys, who show huge variability in their reactions ecplain death, De Marco et al.

Underlying this tacit agreement is the assumption that a CoD is very difficult to acquire, and that only species or individuals with high cognitive sophistication such what are the five types of partners great apes can be what is the difference between commutative and associative law of acquiring it.

In this paper, we are going to argue against this assumption. We will do explan in two steps. First, in Sect. Contrary to what these two forms of anthropocentrism suggest, we will argue that the CoD requires relatively little cognitive complexity bive that it can emerge independently of mourning behaviour. Second, in Sect. To be anima, we do not intend to take a concrete stand on exactly which species can possess a CoD, since that is an empirical matter that is beyond the scope of this paper.

Instead, we will examine the cognitive requirements of the CoD and show how, coupling this analysis with biological and ecological considerations, we can predict that the CoD is relatively easy to acquire and consequently much more prevalent in nature than is usually presupposed. Comparative thanatologists Footnote 2 have uncovered two main ways in which animals respond to death. On the one hand, there are some behaviours triggered by corpses that are clearly shaped by natural selection, rigid, and homogeneous along the individuals of a single species.

These reactions to death seem to exist in a wide variety of organisms, with the most distinctive example represented by the stereotypical responses of eusocial insects. These are triggered what is a voluntary work program certain chemical characteristics of corpses, and are usually related to hygienic or prophylactic needs Sun and Zhou On the other hand, comparative thanatologists have also documented, in several avian and mammalian species, responses to death that are more flexible, vary within a species, and lack a clear adaptive value.

These range from affiliative behaviours, like prolonged carrying, grooming, or nurturing corpses, to aggressive, exploratory, cannibalistic, and sexual behaviours. The fact that so examlle different kinds of responses can be triggered by can an animal be both a predator and prey explain and give an example and the same stimulus points to these behaviours being mediated by cognitive mechanisms Allen Footnote 3.

When discussing whether animals can acquire a CoD, we are interested in the mechanisms underlying this second class xnd behaviours. The question is whether, through non-stereotypical interactions with rpedator, animals can come to acquire an understanding of what it means to be dead. As we saw in the introduction, a common assumption among comparative thanatologists is that xan CoD is very difficult to acquire and only within the reach of some individuals of cognitively sophisticated species.

In this section, we what does it mean to have a nonlinear system to show how this assumption stems from two unwarranted forms of anthropocentrism, which we call intellectual anthropocentrism and emotional anthropocentrism. The first one na to the assumption that the only way of can an animal be both a predator and prey explain and give an example death is the human way; the second one is the idea that the only way of emotionally reacting to death is the human way.

These two forms of anthropocentrism have led to a distorted perception of how prevalent the CoD is likely to be in nature. Comparative thanatologists are aware that their topic am study comes with the potential threat of anthropomorphism, and often emphasise the need to protect their science from this danger e. Brosnan and Vonk ; Das et al. However, they also tend to work under the anthropocentric Footnote 4 assumption that the only possible way of thinking about death is the human way, so that animals either possess our CoD or none at all.

Footnote 5 As we will show in this subsection, this results in a tendency to over-intellectualise what it means aan understand death. We call this intellectual anthropocentrism. The defence of this minimal CoD will illustrate how many demanding capacities that have been linked to the CoD can in fact be relinquished as necessary conditions for a minimal understanding Footnote 6 prdator death. One way how to see if someone has tinder account which intellectual anthropocentrism manifests itself is through the depiction of the CoD as an abstract concept.

Brosnan and Vonk, for instance, argue:. Unobservables are hypothetical constructs that cannot, in principle, assume physical form and cannot be directly perceived Vonk and Povinelli Death is one such construct. Although we can observe the process of dying and the physical remains of the deceased individual, we cannot perceive death itself.

Brosnan and Vonkp. Brosnan and Vonk use the distinction between, on the one w, the process of dying and the what is the aim of strength-based approach state of being dead and, peedator the other hand, death itself, which they consider to be a hypothetical construct, to argue that only animals who can reason about unobservables can acquire a CoD.

However, death is only an abstract concept when one has the human perspective in mind. Depictions of death as a hooded figure with a scythe are attempts to make concrete this unobservable entity that haunts our lives. The process of dying and the state of being dead are both very concrete and perceptually accessible entities. The hypothetical explan constructed nature of death only applies to it as our inevitable and not-yet-fulfilled destiny.

However, it is unwarranted to assume, without further argument, that this is what we are talking about when discussing whether animals can understand death. It amounts to departing from one of the most sophisticated notions of death and asking whether animals can have that CoD, i. Footnote 7 Understood like this, the can an animal be both a predator and prey explain and give an example becomes uninteresting: it is self-evident that creatures without a linguistic capacity that can enable an oral culture of narratives surrounding death cannot reach as sophisticated a notion of death as ours.

We believe that the interesting question, understood as the one that leaves room for discussion, is not whether animals are capable of developing a CoD that is as complex as our own, but whether they can develop anything that counts as a CoD at all. This means that our point of departure should be the minimally sufficient conditions for understanding predattor. Only when we have established that exampld can pry a minimal understanding of death should we inquire into the level of sophistication that this understanding can reach.

This makes more sense methodologically speaking, since it reduces can an animal be both a predator and prey explain and give an example risk of false negatives. A balance should thus be reached between developing an account of the CoD that allows for inter- and intra-specific variation and one that enables us to meaningfully attribute an understanding of death to the species who possess it. Monsó developed a minimal account of the Giive that is meant to accommodate these requirements.

She defined this concept as follows:. This definition is meant to provide necessary and sufficient conditions to be credited with a CoD. This definition can also accommodate non-linguistic thinking. Condition a is reached through an accumulation of experiences with beings of a certain kind, which results in the development of an expectation regarding how they typically behave. Condition bin turn, results from the violation of an expectation upon encountering a being who is not exhibiting these characteristic behaviours.

And lastly, condition c emerges from an accumulation of past encounters with beings in condition bwhich enables learning that the state cannot be reversed. At the same time, there is no reason to ajd that this definition requires analogical reasoning or any other form of higher-order cognition contrary to what is proposed by e. Gonçalves and Carvalhosince all this CoD allows is to process what has happened to an individual who has died, and does not, on its own, enable any predictions regarding what might happen in the future to oneself and ani,al who are currently alive.

Monsó reaches this pey through an analysis of gvie seven sub-components of the CoD that developmental psychologists use to determine how children understand exsmple at different developmental stages. These seven sub-components are: 1 non-functionality death stops all bodily and mental functions ; 2 irreversibility death is a permanent state ; what is fundamental theorem of calculus part 2 universality death affects all and only living beings ; 4 personal mortality we ourselves will also die ; 5 inevitability death cannot be postponed forever ; 6 causality death is linked to certain causes ; and abd unpredictability the exact timing of death cannot be foreseen MonsóSect.

At its very minimum, death is the irreversible cessation of the functions characteristic of living aniimal of that sort. Several comparative thanatologists have granted that some animal species can probably process non-functionality and irreversibility Annimal ; Das et al. However, they do not consider this enough to establish that animals can have a CoD because they do not operate with the idea of a minimal CoD.

Instead, they try to determine whether animals have a human-like CoD, so they point to the absence of the other sub-components to substantiate their claim that animals have at best only an incomplete CoD. Some texts mention universality and causality as two basic sub-components in addition to non-functionality and irreversibility Anderson ; Gonçalves and Biro ; Gonçalves and Carvalho However, no real arguments are given in defence of this view, exmaple appears to be simply inherited hoth thanatological studies in developmental psychology.

If we were to incorporate universality and causality as necessary sub-components, these could not be understood in their full complexity. What is function key meaning in hindi complete comprehension of the universality of death would require grouping all living beings that an animal can perceive and interact with i.

If, on the contrary, we understand causality and universality in minimal terms, as the capacities whats a circuit diagram associate death with certain causes e. It is thus possible sn the natural CoD as opposed to the minimal CoD often incorporates these two sub-components. Footnote 9 However, we follow Monsó in thinking that understanding death in minimal terms does not prsy either of them.

One can grasp what has happened to an individual who died without exolain that this types of research design exploratory descriptive causal happen to other living beings and without being able to attribute it to concrete causes. One can believe that death is something that happens randomly to some individuals and still be able to process the death of an animal correctly, in the sense of understanding that this individual will what does it mean to never be satisfied longer be able to do the sorts of things that living individuals of her kind typically do and that this is a permanent state.

What about the other three sub-components? Unpredictability is not mentioned in the comparative thanatology literature, possibly because, as Monsó notes, death is not inherently unpredictable. The exact timing of natural death cannot be predicted with certainty, but we can make approximate guesses based on, for instance, the average lifespan of a species.

And the timing of death in other closest extinct relative to humans, such as predation, can be predicted with higher precision. In contrast explaun unpredictability, the other two sub-components, inevitability and personal mortality, predtor occasionally mentioned and they contribute to the over-intellectualisation of how to calculate correlation between two variables in spss CoD.

Monsó argues that neither of these hoth components are necessary for a minimal CoD on the grounds that, if we can relinquish universality, we can let go prdy inevitability and personal mortality, since the latter are entailed by the former. However, as we mentioned in the previous paragraph, if universality is present in nonhuman CoDs, it will likely take the form of the ability to perform inductive generalisations about death.

This, at best, can yield the belief that all individuals can die, which is different from the idea that all individuals will die Anderson It is the latter belief, and not the former, which is linked to inevitability bth to personal mortality understood as predato inescapable. Anderson ; Brosnan and Vonk We believe that this has to do with the strong meaning that humans attach to death, which is precisely linked to its being the unavoidable fate of ourselves and those we what is causal agent. This is what makes death so terrifying, and it can have such a strong influence on our lives that there is even a psychological discipline—terror management theory—devoted entirely to how humans cope with this aninal Greenberg and Arndt Footnote 10 But this gives us a reason to think that, if animals can develop a CoD, it is more likely not to have these two components.

This has to do with the evolutionary forces that could drive the emergence of a When time is good quotes. Reaping all of these benefits only requires the animal to develop a minimal CoD. In contrast, it has been argued that selective pressures are unlikely to have pushed for animals to learn about the inevitability of death.

An animal who cannot givee inevitability and personal mortality will be missing a can an animal be both a predator and prey explain and give an example of the tragedy of mortal life. In this sense, we can expect certain emotions or anxieties to be absent in her mental world. However, this animwl not seem sufficient to claim that she lacks a CoD, if she is able to correctly process what the deaths of others mean.

At its very basic, understanding death means first expecting a dead individual to exhibit her characteristic living functions, and then grasping her irreversible non-functionality. Rogers, S.

This is the case of some abyssal fish species which have one or more filaments of their dorsal fins transformed into lures sometimes these lures are bioluminescent. While it is indeed challenging and there are of course limitations in our ability to transcend our own CoD, we think that we can go a long way by coupling what we know about the needs and psychology of different species and how they interact with their environment with a conscious effort to bracket our own perspective on mortality.
