The starting point of this conversation with philosopher Mathieu Triclot is the issue of the causal contribution of video game playing in school shootings. Triclot explains the limitations of current psychological approaches regarding video game violence. He further develops on the peculiar features of the video game medium and how they relate to the problem of violence. Triclot eventually shows that, although players may relate to virtual violence in very different ways, violence in video games is not merely a (...) subjective phenomenon. He highlights that some “regimes of experience,” which got stable in the video game culture, cultivate a toxic relation to violence. (shrink)

The second half of the third/ninth and the fourth/tenth centuries are of particular importance for the development of the judiciary in the central lands of the Abbasid caliphate. At the end of the mihna period and the victory of Sunnism under al-Mutawakkil (r. 232-247/847-861), the caliphate agreed not to interfere further within the legal sphere, thus allowing the principal schools of law to complete their development toward their classical structure. In Iraq, thanks to the growing independence of the legal sphere (...) and to the political weakness of the caliphate, the qadis increased their judicial freedom. Meanwhile, the political situation in Egypt was very different. The provincial rulers and two successive dynasties, the Tulunids (254-292/868-905) and the Ikhshidids (323-358/935-969), profited from the weakness of the caliphate, and imposed their autonomy de facto. The role played by the judiciary in this process is still unclear, as is the impact of Egyptian autonomy on the development of the local judiciary. In this paper, I discuss the evolution of the relationship between the Egyptian governors and the judiciary, from the accession of Ahmad b. Tulun in 254/868 until the arrival of the Fatimids in 358/969. Several elements are taken into consideration: (1) The institutional links between political power and the judiciary: Who appointed the qadis? How were they selected? Did the government choose to rely on local scholars or did the qadis come from outside the province? (2) The financial connection between the governors and the qadis, which was not only symbolic of the delegation of power, but could also denote the submission of the judiciary to the government. (3) The daily interactions between the qadis and the governors. (4) The judicial practice of the qadis. (5) Their reputation. I study to what extent the judiciary and its control was a political issue for the Tulunids and the Ikhshidids, and how the efforts of these two dynasties to build an Egyptian autonomy had important consequences on the structure of the legal milieu.

There is now an awakening to and recognition of the emotionally complex lives of some non-human animals. While their forms of consciousness may vary, some are indeed conscious and deserve political consideration. What that political consideration ought to be is the central topic of this article. First, I argue that interspecies justice must be understood in terms of the relationships that foster individual flourishing of all concerned. The obstacles to such flourishing are the five faces of oppression famously identified by (...) Iris Marion Young: exploitation, marginalization, powerlessness, cultural imperialism, and violence. By extending Young’s concept of the social group to intra- and interspecies groups, we become more attuned to differences between and among species. Theorizing the existence of interspecies groups brings forward new avenues to explore oppression and simultaneously theorize its opposite – interspecies justice. Second, I argue that a positive theory of interspecies flourishing can be developed on the basis of Marx’s materialist philosophy and reclamation of species-being. Though Marx uses humanist language throughout the Economic and Philosophic Manuscripts of 1844, attention to his methodological commitments reveals that some non-human animals can no longer be excluded from the capability of flourishing and species-being. Some non-human animals are conscious, act purposefully, and labor creatively and must be included in our circle of moral and political concern. (shrink)

A Polish space is not always homeomorphic to a computably presented Polish space. In this article, we examine degrees of non-computability of presenting homeomorphic copies of compact Polish spaces. We show that there exists a $\mathbf {0}'$ -computable low $_3$ compact Polish space which is not homeomorphic to a computable one, and that, for any natural number $n\geq 2$, there exists a Polish space $X_n$ such that exactly the high $_{n}$ -degrees are required to present the homeomorphism type of $X_n$. (...) Along the way we investigate the computable aspects of Čech homology groups. We also show that no compact Polish space has a least presentation with respect to Turing reducibility. (shrink)

This paper presents the first possible world semantics for concessive conditionals (i.e., even if A, C conditionals) constructed in a compositional way. First, the meaning of if is formalized through a semantics that builds on the proposal given by Stalnaker (1968). A major difference from Stalnaker’s approach is that irrelevant conditionals (i.e., conditionals where the antecedent and the consequent have no connection) are false in this new setting. Second, the meaning of even is analyzed through a formal semantics based on (...) the notion of scale. This analysis overcomes the problems arising in standard approaches, in which even is analyzed with the help of pragmatic presuppositions. Finally, the two particles are combined in order to provide a formal analysis of even if. This theory predicts the major phenomena concerning the behavior of concessive conditionals and without any call to pragmatic explanations. More generally, this approach creates the possibility of a compositional analysis of other conditionals such as if then or only if forms. (shrink)

After sketching an argument for radical anti-realism that does not appeal to human limitations but polynomial-time computability in its definition of feasibility, I revisit an argument by Wittgenstein on the surveyability of proofs, and then examine the consequences of its application to the notion of canonical proof in contemporary proof-theoretical-semantics.

High-fidelity cultural transmission, rather than brute intelligence, is the secret of our species’ success, or so many cultural evolutionists claim. It has been selected because it ensures the spread, stability and longevity of beneficial cultural traditions, and it supports cumulative cultural change. To play these roles, however, fidelity must be a causally-efficient property of cultural transmission. This is where the grain problem comes in and challenges the explanatory potency of fidelity. Assessing the degree of fidelity of any episode or mechanism (...) of cultural transmission always depends upon an investigator’s choice of grain of description at which cultural traditions are being studied. The fidelity of cultural transmission then appears to be relative to the granularity at which one approaches cultural variation, and since there is a multiplicity of grains of description by which the same tradition can be studied, there results a multiplicity of measures of fidelity for a same event or mechanism of cultural transmission. If this is correct, because fidelity is always relative to the grain of description dictated by the local and specific research interests of the investigator, then there seems to be no fact of the matter as to whether cultural transmission is faithful or not, independently from a researcher’s framework of analysis. The aims of this paper are to offer a conceptual clarification of the grain problem in cultural evolution, to assess its causes, to unpack its epistemological implications, and to examine its reach and consequences for a science of cultural evolution.

A leading idea of cultural evolutionary theory is that for human cultures to undergo evolutionary change, cultural transmission must generally serve as a high-fidelity copying process. In analogy to genetic inheritance, the high fidelity of human cultural transmission would act as a safeguard against the transformation and loss of cultural information, thus ensuring both the stability and longevity of cultural traditions. Cultural fidelity would also serve as the key difference-maker between human cumulative cultures and non-human non-cumulative traditions, explaining why only (...) us humans, with our uniquely high-fidelity transmission capabilities, are capable of evolving and sustaining complex traditions. But what does it mean for cultural transmission to be more or less faithful? This article has two objectives. The first is to clarify the meaning and uses of the concept of cultural fidelity and to evaluate their explanatory import. I argue that cultural evolutionists use several fidelity concepts (episodic, propensity, and generalized fidelity), concepts that I will define and clarify. The second objective is to challenge the explanatory significance of a general notion of fidelity (generalized fidelity) as being both explanatorily meaningful and operationalizable. I conclude that if fidelity is to serve as an explanation of the key differences between human cumulative cultures and non-human non-cumulative traditions, then the concept will have to be redesigned and rely on different assumptions. 1Introduction 2Generalized Fidelity 2.1The need for an explanatory concept of fidelity 2.2Three conditions for a general notion of cultural fidelity 3Episodic Fidelity 3.1Measuring episodic fidelity 3.2The relevance problem 3.3Explanatory pluralism 3.4The incommensurability of fidelity metrics 4Propensity Fidelity 5Fidelity as an Explanatory Concept 5.1Explaining cultural stability 5.2Explaining human distinctiveness 6Conclusion.

Everyone, according to W.A. Mathieu, is musical by nature--it goes right along with being human. And if you don't believe it, this book will convince you. In a series of interrelated short essays, Mathieu takes the reader on a journey through ordinary experiences to open our ears to the rich variety of music that surrounds us but that we are trained to ignore; such as the variety of pitches produced by different objects, like glassware, furniture, drums--anything you can (...) tap; or sounds that hover on the border of music, like laughter, the clinking of glasses in a toast, or the unintentional falsetto produced by yawning. Along the way the author teaches aspects of music theory that nonmusicians might ordinarily shy away from. He reveals the way of music to be a profoundly spiritual path--one that is everyone's birthright. (shrink)

In this paper, elementary but hitherto overlooked connections are established between Wittgenstein's remarks on mathematics, written during his transitional period, and free-variable finitism. After giving a brief description of theTractatus Logico-Philosophicus on quantifiers and generality, I present in the first section Wittgenstein's rejection of quantification theory and his account of general arithmetical propositions, to use modern jargon, as claims (as opposed to statements). As in Skolem's primitive recursive arithmetic and Goodstein's equational calculus, Wittgenstein represented generality by the use of free (...) variables. This has the effect that negation of unbounded universal and existential propositions cannot be expressed. This is claimed in the second section to be the basis for Wittgenstein's criticism of the universal validity of the law of excluded middle. In the last section, there is a brief discussion of Wittgenstein's remarks on real numbers. These show a preference, in line with finitism, for a recursive version of the continuum. (shrink)

For a population to undergo evolution by natural selection, it is assumed that the constituents of the population form parent-offspring lineages, that is, that they must reproduce. I challenge this assumption by dividing the notion of reproduction into two subprocesses, that is, multiplication and inheritance, that produce parent-offspring lineages between the parts of a population, and I show that their population-level roles, generation and memory, respectively, can be effected by processes that do not rely on such local-level lineages. I further (...) argue that these two population-level processes, not local parent-offspring lineages, are necessary conditions for a population to undergo Darwinian evolution. (shrink)

For a little over a decade we have been witnessing a profusion of discourses on autochthony — that is, an original belonging to a group or territory — in many parts of the world. A global approach to this question first requires a look at the principle of autochthony and its genealogy. Starting from African examples, places of prolific expression of the phenomenon, this article shows how autochthony plays the role of capital that can be invested, valued and profited from. (...) The structure of this capital carries within itself the seeds of conflict. The article analyses how the stabilization of its value requires the execution of specific strategies. Among these strategies, I will focus in greater depth on voting. The relationship between capital, autochthony and elections will thus bring us back to debates that animate political science: in new municipalities, autochthony as capital is at the heart of candidate selection, suffrage, political participation and citizenship.

In this paper, I stress the utility of employing test-driven development (TDD) for conceiving logical systems. TDD, originally invented in the context of Extreme Programming, is a methodology widely used by software engineers to conceive and develop programs. Its main principle is to design the tests of the expected properties of the system before the development phase. I argue that this methodology is especially convenient in conceiving applied logics. Indeed, this technique is efficient with most decidable logics having a software (...) implementation. Having a clear list of the desired inferences right from the beginning makes it possible to refine the properties of the system step by step until its completion. I distinguish and detail seven advantages of the usage of TDD for the conception of a logical theory. Most importantly, this methodology increases the predictability of the inferential power of the theory. A second important benefit is that the time required for the conception of the logic goes down dramatically. This methodology will change both ideas and practices. Logic is no longer considered to be a formal science, but rather to be an empirical one. Research in the field is geared toward specific and concrete goals. Programs are considered tools used to verify the conformity of formal theories. To sum up, I defend the view that, in some situations, this way of designing a formal system brings significant benefits, and that the construction of new logics can be conducted similarly to the development of open source software.

Prior work on weakness of will has assumed that it is a thoroughly psychological phenomenon. At least, it has assumed that ordinary attributions of weakness of will are purely psychological attributions, keyed to the violation of practical commitments by the weak-willed agent. Debate has recently focused on which sort of practical commitment, intention or normative judgment, is more central to the ordinary concept of weakness of will. We report five experiments that significantly advance our understanding of weakness of will attributions (...) by showing that the ordinary concept of weakness of will is less thoroughly psychological than the philosophical debate has assumed. We begin by showing that a sizable minority of people attribute weakness of will even in the absence of a violated commitment (Experiment 1). We then show that weakness of will attributions are sensitive to two important non-psychological factors. First, for actions stereotypically associated with weakness of will, the absence of certain commitments often triggers weakness of will attributions (Experiments 2–4). Second, the quality of an action’s outcome affects the extent to which an agent is viewed as weak-willed: actions with bad consequences are more likely to be viewed as weak-willed (Experiment 5). Our most important finding is that the ordinary concept of weakness of will is sensitive to two non-psychological factors and is thus much broader than philosophers have thus far imagined. We conclude by suggesting a two-tier model that unites our findings with traditional philosophical theorizing about weakness of will. (shrink)

La philosophie de l’histoire d’Auguste Comte, méconnue aujourd’hui, mérite un nouvel examen. L’idée de progrès social qui lui sert de fil conducteur s’éclaire lorsqu’on la compare à la hiérarchie animale telle qu’elle est conçue notamment par Lamarck et Blainville. De ce point de vue, on s’aperçoit que les critiques déjà formulées par Cuvier envers une telle hiérarchie préfigurent celles qu’on peut adresser à la conception comtienne de l’histoire, qui semble postuler une corrélation trop rigide entre les différents aspects sociaux. Mais (...) ne peut-on pas alors interpréter les idées de progrès social et de hiérarchie animale comme des principes régulateurs et non des faits observables? (shrink)

This article focuses on defective conditionals ? namely indicative conditionals whose antecedents are false and whose truth-values therefore cannot be determined. The problem is to decide which formal connective can adequately represent this usage. Classical logic renders defective conditionals true whereas traditional mathematics dismisses them as irrelevant. This difference in treatment entails that, at the propositional level, classical logic validates some sentences that are intuitively false in plane geometry. With two proofs, I show that the same flaw is shared by (...) a family of trivalent logics. I go on to examine the strict conditional and its derivatives. This family is the only one to avoid the faulty inference but it does so without addressing the status of the truth-value assigned to defective conditionals. (shrink)

Codes of medical ethics (codes) are part of a longstanding tradition in which physicians publicly state their core values and commitments to patients, peers, and the public. However, codes are not static. Using the historical evolution of the Canadian Medical Association's Code of Ethics as an illustrative case, we argue that codes are living, socio-historically situated documents that comprise a mix of prescriptive and aspirational content. Reflecting their socio-historical situation, we can expect the upheaval of the COVID-19 pandemic to prompt (...) calls to revise codes. Indeed, Alex John London has argued in favour of specific modifications to the World Medical Association's International Code of Medical Ethics (which has since been revised) in light of moral and scientific failures that occurred during the COVID-19 pandemic. Responding to London, we address the more general question: should codes be modified to reflect lessons drawn from the COVID-19 pandemic or future such upheavals? We caution that codes face limitations as instruments of policy change because they are inherently interpretive and ‘multivocal’, that is, they usually underdetermine or provide more than one answer to the question, ‘What should I do now?’ Nonetheless, as both prescriptive and aspirational documents, codes also serve as tools for reflection and deliberation—collective practices that are necessary to engaging with and addressing the moral and scientific uncertainties inherent to medicine.

We know from Li's theorem (1993) that the stability set of order d may be empty for some preference profiles. However, one may wonder whether such situations are just rare oddities or not. In this paper, we partially answer this question by considering the restrictive case where the number of alternatives is the smallest compatible with an empty stability set. More precisely, we provide an upper bound on the probability for having an empty stability set of order d for the (...) majority game under the Impartial Weak Ordering Culture assumption. This upper bound is already extremely low for small population and tends to zero as the number of individuals goes to infinity. (shrink)

Plagiarism is a crime against academy. It deceives readers, hurts plagiarized authors, and gets the plagiarist undeserved benefits. However, even though these arguments do show that copying other people’s intellectual contribution is wrong, they do not apply to the copying of words. Copying a few sentences that contain no original idea (e.g. in the introduction) is of marginal importance compared to stealing the ideas of others. The two must be clearly distinguished, and the ‘plagiarism’ label should not be used for (...) deeds which are very different in nature and importance. (shrink)

According to Clifford Geertz, the purpose of anthropology is not to explain culture but to explicate it. That should cause us to rethink our relationship with machine learning. It is, we contend, perfectly possible that machine learning algorithms, which are unable to explain, and could even be unexplainable themselves, can still be of critical use in a process of explication. Thus, we report on an experiment with anthropological AI. From a dataset of 175K Facebook comments, we trained a neural network (...) to predict the emoji reaction associated with a comment and asked a group of human players to compete against the machine. We show that a) the machine can reach the same accuracy as the players, b) it fails in roughly the same ways as the players, and c) easily predictable emoji reactions tend to reflect unambiguous situations where interpretation is easy. We therefore repurpose the failures of the neural network to point us to deeper and more ambiguous situations where interpretation is hard and explication becomes both necessary and interesting. We use this experiment as a point of departure for discussing how experiences from anthropology, and in particular the tension between formalist ethnoscience and interpretive thick description, might contribute to debates about explainable AI.

In this paper, I examine the transmission of some ideas of the pragmatist tradition to Wittgenstein, in his ‘middle period,’ through the intermediary of F. P. Ramsey, with whom he had numerous fruitful discussions at Cambridge in 1929. I argue more specifically that one must first come to terms with Ramsey’s own views in 1929, and explain how they differ from views expressed in earlier papers from 1925-27, so a large part of this paper is devoted to this task. One (...) is then in a better position to understand the impact of Ramsey’s astute critique of Wittgenstein’s Tractatus Logico-Philosophicus in conjunction with his pragmatism, and explain how it may have set into motion the ‘later’ Wittgenstein. I then argue that Ramsey introduced his notion of ‘variable hypothetical’ as a rule, not a proposition, on pragmatist grounds and that Wittgenstein picked this up in 1929, along with a more ‘dynamic’ view of meaning than the ‘static’ view of the Tractatus, and that this explains in part Wittgenstein’s turn to his ‘later philosophy.’.

In this paper, I present a summary of the philosophical relationship betweenWittgenstein and Brouwer, taking as my point of departure Brouwer's lecture onMarch 10, 1928 in Vienna. I argue that Wittgenstein having at that stage not doneserious philosophical work for years, if one is to understand the impact of thatlecture on him, it is better to compare its content with the remarks on logics andmathematics in the Tractactus. I thus show that Wittgenstein's position, in theTractactus, was already quite close to (...) Brouwer's and that the points of divergence are the basis to Wittgenstein's later criticisms of intuitionism. Among the topics of comparison are the role of intuition in mathematics, rule following, choice sequences, the Law of Excluded Middle, and the primacy of arithmetic over logic. (shrink)

Background The American Association of Medical Colleges has called for incorporation of the health humanities into medical education, and many medical schools now offer formal programs or content in this field. However, there is growing recognition among educators that we must expand beyond empathy and wellness and apply the health humanities to questions of social justice – that is, critical health humanities. In this paper we demonstrate how this burgeoning field offers us tools for integrating social justice into medical education, (...) utilizing the frameworks of critical consciousness and structural competency. Practice of health humanities Critical health humanities can be applied at multiple levels of learners, and in a variety of contexts. We are two physician-writers who have developed several educational programs that demonstrate this. We taught a seminar that introduced first-year and second-year undergraduates to concepts such as social determinants of health, intergenerational trauma, intersectionality, resilience, and cross-cultural care through works of fiction, poetry, film, podcasts, stand-up comedy, and more. Through creative projects and empathic reflection, students engaged with the complexities of structural forces that create and maintain health disparities. Medical students in their clinical years can engage in critical health humanities learning experiences as well. We teach several multidisciplinary electives that address social (in)justice in medicine, as well as mentor fourth-year students engaged in independent electives that foster critical awareness around health equity and ethics. Beyond the classroom, we have actively engaged in critical health humanities practices through story slams, literary journal clubs, conference presentations, and Grand Rounds. Through these activities we have included learners at GME and CME levels. These examples also demonstrate how community engagement and multidisciplinary partnerships can contribute to the practice of critical health humanities. Conclusion In this paper, we explore the growing field of critical health humanities and its potential for teaching health equity through narrative practices. We provide concrete examples of educational activities that incorporate critical consciousness and structural competency – frameworks we have found useful for conceptualizing critical health humanities as a pedagogical practice. We also discuss the strengths and challenges of this work and suggest future directions. (shrink)

We present a formal argumentation system for dealing with the detachment of prioritized conditional obligations and permissions. In the presence of facts and constraints, we answer the question whether an unconditional obligation or permission is detachable by considering arguments for and against its detachment. For the evaluation of arguments in favour of detachment, we use a Dung-style argumentation-theoretical semantics. We illustrate how violations and contrary-to-duty scenarios are dealt with in our framework and pay special attention to conflict-resolution via priorities.

Background: There is increasing evidence to support the efficacy of transcranial direct current stimulation applications in cognitive augmentation and rehabilitation. Neuromodulation achieved with tDCS may further regulate regional cerebral perfusion affiliated through the neurovascular unit; however, components of cerebral perfusion decrease across aging. A novel neuroimaging approach, functional near-infrared spectroscopy, can aid in quantifying these regional perfusional changes. To date, the interaction of the effects of tDCS on cognitive performance across the lifespan and obtained fNIRS hemodynamic responses remain unknown.Objective: This (...) review aims to examine the effects of tDCS on cognitive performance and fNIRS hemodynamic responses within the context of cognitive aging.Methods: Six databases were searched for studies. Quality appraisal and data extraction were conducted by two independent reviewers. Meta-analysis was carried out to determine overall and subgroup effect sizes.Results: Eight studies met inclusion criteria. The overall effect size demonstrates that tDCS can alter cognitive performance and fNIRS signals, with aging being a potential intermediary in tDCS efficacy.Conclusion: From the studies included, the effects of tDCS on cognitive performance and fNIRS metrics are most prominent in young healthy adults and appear to become less robust with increasing age. Given the small number of studies included in this review further investigation is recommended. (shrink)

The study of ergodic theorems from the viewpoint of computable analysis is a rich field of investigation. Interactions between algorithmic randomness, computability theory and ergodic theory have recently been examined by several authors. It has been observed that ergodic measures have better computability properties than non-ergodic ones. In a previous paper we studied the extent to which non-ergodic measures inherit the computability properties of ergodic ones, and introduced the notion of an effectively decomposable measure. We asked the following question: if (...) the ergodic decomposition of a stationary measure is finite, is this decomposition effective? In this paper we answer the question in the negative. (shrink)

Abstract: This paper considers the question of whether it is possible to be mistaken about the content of our first-order intentional states. For proponents of the rational agency model of self-knowledge, such failures might seem very difficult to explain. On this model, the authority of self-knowledge is not based on inference from evidence, but rather originates in our capacity, as rational agents, to shape our beliefs and other intentional states. To believe that one believes that p, on this view, constitutes (...) one's belief that p and so self-knowledge involves a constitutive relation between first- and second-order beliefs. If this is true, it is hard to see how those second-order beliefs could ever be false.I develop two counter-examples which show that despite the constitutive relation between first- and second-order beliefs in standard cases of self-knowledge, it is possible to be mistaken, and even self-deceived, about the content of one's own beliefs. These counter-examples do not show that the rational agency model is mistaken—rather, they show that the possibility of estrangement from one's own mental life means that, even within the rational agency model, it is possible to have false second-order beliefs about the content of one's first-order beliefs. The authority of self-knowledge does not entail that to believe that one believes that p suffices to make it the case that one believes that p. (shrink)

Social transmission is at the core of cultural evolutionary theory. It occurs when a demonstrator uses mental representations to produce some public displays which in turn allow a learner to acquire similar mental representations. Although cultural evolutionists do not dispute this view of social transmission, they typically abstract away from the multistep nature of the process when they speak of cultural variants at large, thereby referring both to variation and evolutionary change in mental representations as well as in their corresponding (...) public displays. This conflation suggests that differentiating each step of the transmission process is redundant. In this paper, I examine different forms of interplay between the multistep nature of social transmission and the metric spaces used by cultural evolutionists to measure cultural variation and to model cultural change. I offer a conceptual analysis of what assumptions seem to be at work when cultural evolutionists conflate the complex causal sequence of social transmission as a single space of variation in which populations evolve. To this aim, I use the framework of variation spaces, a formal framework commonly used in evolutionary biology, and I develop two theoretical concepts, ‘technique’ and ‘technical space’, for addressing cases where the complexity of social transmission defies the handy assumption of a single variation space for cultural change.

The complexity of the physiological phenotype currently prevents us from identifying an integrative measure to assess how the internal state and environmental conditions modify life‐history strategies. In this article, it is proposed that shorter telomeres should lead to a faster pace‐of‐life where investment in self‐maintenance is decreased as a means of saving energy for reproduction, but at the cost of somatic durability. Inversely, longer telomeres would favor an increased investment in soma maintenance and thus a longer reproductive lifespan (i.e., slower (...) pace‐of‐life). Under this hypothesis, telomere dynamics could be such an integrative mediator, which will assemble the information about oxidative stress levels, inflammation status and stress reactivity, and relate this information to the potential lifespan of the organism and its pace‐of‐life strategy. The signaling function of telomere dynamics can also reach over generations, a phenomenon in which the telomere lengths of gametes would provide a channel through which offspring would receive information about their environment early in their development, hence increasing the possibilities for developmental plasticity. -/- .

In fungi, cell fusion between genetically unlike individuals triggers a cell death reaction known as the incompatibility reaction. In Podospora anserina, the genes controlling this process belong to a gene family encoding STAND proteins with an N‐terminal cell death effector domain, a central NACHT domain and a C‐terminal WD‐repeat domain. These incompatibility genes are extremely polymorphic, subject to positive Darwinian selection and display a remarkable genetic plasticity allowing for constant diversification of the WD‐repeat domain responsible for recognition of non‐self. Remarkably, (...) the architecture of these proteins is related to pathogen‐recognition receptors ensuring innate immunity in plants and animals. Here, we hypothesize that these P. anserina incompatibility genes could be components of a yet‐unidentified innate immune system of fungi. As already proposed in the case of plant hybrid necrosis or graft rejection in mammals, incompatibility could be a by‐product of pathogen‐driven divergence in host defense genes. (shrink)
