The field of language evolution has recently made Gricean pragmatics central to its task, particularly within comparative studies between human and non-human primate communication. The standard model of Gricean communication requires a set of complex cognitive abilities, such as belief attribution and understanding nested higher-order mental states. On this model, non-human primate communication is then of a radically different kind to ours. Moreover, the cognitive demands in the standard view are also too high for human infants, who (...) nevertheless do engage in communication. In this paper I critically assess the standard view and contrast it with an alternative, minimal model of Gricean communication recently advanced by Richard Moore. I then raise two objections to the minimal model. The upshot is that this model is conceptually unstable and fails to constitute a suitable alternative as a middle ground between full-fledged human communication and simpler forms of non-human animal communication.

“The Ethics of Infection Challenges in Primates,” by Anne Barnhill, Steven Joffe, and Franklin Miller, is an exceptionally timely contribution to the literature on animal research ethics. Animal research has long been both a source of high hopes and a cause for moral concern. When it comes to infection challenge studies with nonhuman primates, neither the hope—to save thousands of human lives from such diseases as Ebola and Marburg—nor the concern—the conviction that primates deserve especially strong protections—could be much higher. (...) Coming just a few years after the National Institutes of Health adopted the Institute of Medicine's recommendations regarding chimpanzees, Barnhill and colleagues attempt to nudge the clarification and specification—one might say the evolution—of NHP research ethics and regulation. They assert that NHP challenge studies “are not justified by marginal gains in human safety or by efficacy gains that are unlikely to translate directly into saving human lives or preventing morbidity.” How, in turn, is their standard—which, although stringent, does permit causing NHPs to suffer and die for human benefit—to be justified?

Self-consciousness is a product of evolution. Few people today disagree with the evolutionary history of humans. But the nature of self-consciousness is still to be explained, and the story of evolution has rarely been used as a framework for studies on consciousness during the 20th century. This last point may be due to the fact that modern study of consciousness came up at a time where dominant philosophical movements were not in favor of evolutionist theories (Cunningham 1996). Research (...) on consciousness based on Phenomenology or on Analytic Philosophy has been mostly taking the characteristics of humans as starting points. Relatively little has been done with bottom-up approaches, using performances of animals as a simpler starting point to understand the generation of consciousness through evolution. But this status may be changing, thanks to new tools coming from recent discoveries in neurology. The discovery of mirror neurons about ten years ago (Gallese et al. 1996, Rizzolatti et al. 1996) has allowed the built up of new conceptual tools for the understanding of intersubjectivity within humans and non human primates (Gallese 2001, Hurley 2005). Studies in these fields are still in progress, with discussions on the level of applicability of this natural intersubjectivity to non human primates (Decety and Chaminade 2003). We think that these subject/conspecific mental relations made possible by mirror neurons can open new paths for the understanding of the nature of self-consciousness via an evolutionist bottom-up approach. We propose here a scenario for the build up of self-consciousness through evolution by a specific analysis of two steps of evolution: first step from simple living elements to non human primates comparable to chimpanzees, and second step from these non human primates to humans. We identify these two steps as representing the evolution from basic animal awareness to body self-awareness, and from body self-awareness to self-consciousness. (we consider that today non human primates are comparable to what were pre-human primates). We position body self-awareness as corresponding to the performance of mirror self recognition as identified with chimpanzees and orangutans (Gallup). We propose to detail and understand the content of this body self-awareness through a specific evolutionist build up process using the performances of mirror neurons and group life. We address the evolutionary step from body self-awareness to self-consciousness by complementing the recently proposed approach where self-consciousness is presented as a by-product of body self-awareness amplification via a positive feedback loop resulting of anxiety limitation (Menant 2004). The scenario introduced here for the build up of self-consciousness through evolution leaves open the question about the nature of phenomenal-consciousness (Block 2002). We plan to address this question later on with the help of the scenario made available here. (shrink)

This is a joint review of Shirley Strum and Linda Fedigan's Primate Encounters: Models of Science, Gender, and Society (Chicago, 2000) and Sarah Blaffer Hrdy, Mother Nature: A History of Mothers, Infants, and Natural Selection (Pantheon, 1999).

First-person and third-person perspectives are different items of human consciousness. Feeling the taste of a fruit or being consciously part of a group eating fruits call for different perspectives of consciousness. The latter is about objective reality (third-person data). The former is about subjective experience (first-person data) and cannot be described entirely by objective reality. We propose to look at how these two perspectives could be rooted in an evolutionary origin of human consciousness, and somehow be connected. Our starting point (...) is a scenario describing how evolution could have transformed a non self-conscious auto-representation into a conscious self-representation (Menant 2006). The scenario is based on the performance of inter-subjectivity existing among non human primates (Gardenfors 2006). A key item of the scenario is the identification of the auto-representation of a subject with the representations that the subject has of her conspecifics, the latter feeding the former with the meaning: “existing in the environment”. So during evolution, pre-human primates were brought to perceive their auto-representation as existing in the environment. Such process could have generated the initial elements of a conscious self-representation. We take this scenario as providing a possible rooting of human consciousness in evolution. We develop here a part of this scenario by expliciting the inward and outward components of the non self-conscious auto-representation. Inward components are about proprioception and interoception (thirst, pain, …). Outward components cover the sensory information relative to the perception of the body (seen feet, … ) and of its effects on the environment. We consider that the initial elements of a conscious self-representation have been applied to both inward and outward components of the auto-representation. We propose that the application to inward components made possible some first-person information, and that the application to outward components brought up third-person information. Relations between the two perspectives are highlighted. Such approach can root first-person and third-person perspectives in the same slot of human evolution. We conclude by a summary of the above and introduce a possible application of this approach to the concepts of bodily self and of pre-reflexive self-consciousness (Legrand, 2006). (shrink)

Primatology tells that about seven million years ago a split began in primate evolution, a split that led to chimpanzee and human lineages (the pan-homo split). During these millions of years our human lineage has developed performances that our chimpanzee cousins do not possess, like reflective self-consciousness and language. We present here an evolutionary scenario that proposes a rationale for the pan-homo split. It is based on a pre-human anxiety that may have barred access to self-consciousness for the (...) chimpanzee lineage. The starting point of the scenario is the capability that had our pre-human ancestors for an elementary identification with conspecifics. We consider that the evolution of that capability has led to self-consciousness when identifications with conspecifics brought our ancestors to represent their own entity as existing, like conspecifics were represented. But the same identification process also took place with endangered and dying conspecifics. And this has produced a huge anxiety increase, source of important mental sufferings that our ancestors had to limit. Our hypothesis is that different modes of anxiety limitation have led to the pan-homo split. On one side the chimpanzee lineage would have limited an unbearable mental suffering by stopping the development of identifications with conspecifics, and by this also stopping a possible evolution toward self-consciousness. Such anxiety limitation process has led to today chimpanzees which possess a very limited consciousness of themselves. On the other side, our human lineage would have successfully developed anxiety limitation tools like caring, pleasure, anticipation, communication and imitation. With these tools accelerating the evolution of our lineage toward our human mind. The proposed pan/homo split process complements an existing evolutionary scenario for self-consciousness that has positioned anxiety management as a key contributor to the build-up of our human minds. Such overall perspective makes anxiety management a major source to many of our motivations and mental states, much more than assumed so far. Continuations are proposed for a better understanding about our modes of anxiety limitation (including evil behaviors), and also to introduce a possible evolutionary nature of phenomenal consciousness.

This paper will outline a series of changes in the archaeological record related to Hominins. I argue that these changes underlie the emergence of the capacity for strategic thinking. The paper will start by examining the foundation of technical skills found in primates, and then work through various phases of the archaeological and paleontological record. I argue that the key driver for the development of strategic thinking was the need to expand range sizes and cope with increasingly heterogeneous environments.

The notion of representation is at the foundation of cognitive sciences and is used in theories of mind and consciousness. Other notions like ‘embodiment’, 'intentionality‘, 'guidance theory' or ‘biosemantics’ have been associated to the notion of representation to introduce its functional aspect. We would like to propose here that a conception of 'usage related' representation eases its positioning in an evolutionary context, and opens new areas of investigation toward self-representation and self-consciousness. The subject is presented in five parts:Following an overall (...) presentation, the first part introduces a usage related representation as being an information managed by a system submitted to a constraint that has to be satisfied. We consider that such a system can generate a meaningful information by comparing its constraint to a received information (Menant 2003). We define a representation as being made of the received information and of the meaningful information. Such approach allows groundings in and out for the representation relatively to the system. The second part introduces the two types of representations we want to focus on for living organisms: representations of conspecifics and auto-representation, the latter being defined without using a notion of self-representation. Both types of representations have existed for our pre-human ancestors which can be compared to today great apes.In the third part, we use the performance of intersubjectivity as identified in group life with the presence of mirror neurons in the organisms. Mirror neurons have been discovered in the 90‘s (Rizzolatti & al.1996, Gallese & al.1996). The level of intersubjectivity that can be attributed to non human primates as related to mirror neurons is currently a subject of debate (Decety 2003). We consider that a limited intersubjectivity between pre-human primates made possible a merger of both types of representations. The fourth part proposes that such a merger of representations feeds the auto-representation with the meanings associated to the representations of conspecifics, namely the meanings associated to an entity perceived as existing in the environment. We propose that auto-representation carrying these new meanings makes up the first elements of self-representation. Intersubjectivity has allowed auto-representation to evolve into self-representation, avoiding the homunculus risk. The fifth part is a continuation to other presentations (Menant 2004, 2005) about possible evolution of self-representation into self-consciousness. We propose that identification with suffering or endangered conspecifics has increased anxiety, and that the tools used to limit this anxiety (development of empathy, imitation, language and group life) have provided a positive feedback on intersubjectivity and created an evolutionary engine for the organism. Other outcomes have also been possible. Such approach roots consciousness in emotions. The evolutionary scenario proposed here does not introduce explicitly the question of phenomenal consciousness (Block 1995). This question is to be addressed later with the help of this scenario.The conclusion lists the points introduced here with their possible continuations. (shrink)

This article introduces a special issue on mechanisms in language evolution research. It describes processes relevant for the emergence of protolanguage and the transition thereof to modern language. Protolanguage is one of the key terms in the field of language evolution, used to designate a hypothesised intermediate stage in the emergence of language present in extinct hominins: qualitatively different from non-human primate communication in possessing some, but not all, of the features that characterise modern language. Much debate (...) in language evolution focuses on the exact delineation of these features, as well as the means whereby the transitions occurred: first from non-human primate communication systems to protolanguage, and then from protolanguage to modern language. In what follows, we first propose a comprehensive typology of protolanguage debates, taking into account the postulated structural organisation of protolanguage, its functions, and its communicative modality. This makes it possible to show how a specific focus on mechanisms and processes deemed relevant for the emergence of these features allows us to assess the explanatory scope of the existing theories of protolanguage.

Philosophical inquiries into morality are as old as philosophy, but it may turn out that morality itself is much, much older than that. At least, that is the main thesis of prima- tologist Frans De Waal, who in this short book based on his Tanner Lectures at Princeton, elaborates on what biologists have been hinting at since Darwin’s (1871) book The Descent of Man and Hamilton’s (1963) studies on the evolution of altruism: morality is yet another allegedly human characteristic (...) that turns out to be built over evolutionary time by natural.

Phillips et al. make a compelling case for a reversal in the current paradigm in “other minds” research by considering the representation of other people's knowledge more basic than the attribution of belief. Unfortunately, they only discuss primates. In this commentary, I argue that the representation of others' knowledge is an evolutionary ancient trait, first appearing during the Cambrian explosion.

The evolution from pre-human primates to modern Homo sapiens is a complex one involving many domains, ranging from the material to the social to the cognitive, both at the individual and the community levels. This article focuses on a critical qualitative transition that took place during this evolution involving both the social and the cognitive domains. For the social domain, the transition is from the face-to-face forms of social interaction and organization that characterize the non-human primates that reached, (...) with Pan, a hiatus due to the centripetal effects that highly individualized behavior has on a social system. The transition is to the relation-based forms of social organization that evolved in the hominins ancestral to Homo sapiens and are universal in human societies today. For the cognitive domain, this transition involves going from behavior responding mainly to phenomenal level sensory inputs to behavior formed in accordance with the concept of a relation, initially abstracted from behavior patterns, then extending the concept of a relation beyond abstraction from behavior patterns to the concept of a relation generated recursively through constructing the relation of a relation. This extension made possible the construction of systems of relations; initially genealogical systems of relations constructed culturally using the logic of recursion, and subsequently, the symbolic, computational systems of kin term relations referred to by anthropologists as kinship terminologies. The latter are “constructed realities” in the sense this term is used by cultural anthropologists. It follows that the evolution of relation-based systems of social interaction is not adequately accounted for through population model evolutionary accounts such as the Dual Inheritance Theory of human evolution since “constructed realities” constitute collectively and publicly shared cultural knowledge rather than the individually and privately possessed knowledge that is assumed in the population model framework for human evolution.

DARWIN’s (1859, 1871) discoveries have profound ethical implications that continue to be misrepresented and/or ignored. In contrast to socialdarwinistic misuses of his theory, Darwin was a great humanitarian who paved the way for an integrated scientific and ethical world view. As an ethical doctrine, socialdarwinism is long dead ever since its defeat by E. G. Moore although the socialdarwinistic thought is a hard-die in the biological community. The accusations of sociobiology for being socialdarwinistic are unfounded and stem from the moralistic (...) fallacy that is, a false assumption that morality is good by definition. Both social and developmental psychology demonstrate that the moral agency is a motivational device for executing reciprocity that remains at the core of any morality across all studied societies and throughout the ontogeny of moral judgment. The level of true universalizing ethical reflection (KOHLBERG’s postconvential stages or GIBBS’s existential phase) is achieved by a small minority of humans, thus showing that Homo sapiens is a moral but not an ethical animal. While the origin of reciprocity has been perfectly explained by sociobiology, the evolutionary assembly of affective and cognitive elements that make up the moral agency is being successfully studied by the social/personality/developmental psychology as extended to non-human primates. As DARWIN (1871) expected, the key innovation for the evolution of moral agency was the emergence of empathy that evolved independently at least three times: in elephants, dolphins and primates. Empathy has a motivational power of its own; it is also necessary for moral agency that requires two cognitive abilities: reflective self-consciousness and understanding of causality; the two make possible the attribution of responsibility. All these requirements are met by the chimpanzees whose moral agency operates in dyads. In contrast, the human moral agency allows for a third party intervention that opens up vast opportunities for ideologies, especially religions, to use and misuse the moral agency to enforce a reciprocation that may be harmful to both individuals and the entire group. Also, the moral agency is known to enforce enhanced intragroup cohesion and loyalty in response to conflict and war, which suggests that the two prima facie opposed human universals, morality and warfare, may have coevolved. The most important ethical consequence that follows from the increasing understanding of the primate moral agency is that every received morality is ethically flawed, none can be taken as a paragon of goodness, and each needs corrections by science-informed ethics. In fact, Darwin pioneered the integration of science and ethics, an approach that has come to be appreciated only recently under the heading of consilience. (shrink)

Midwest Studies In Philosophy, Volume 44, Issue 1, Page 239-259, December 2019: -/- When people speak or write of “embodied” in one form or another, as in embodied mind, embodied cognition, embodied language, embodied self, and so on, they implicitly look past if not outright deny the realities of evolution. Animate life evolves on the basis of different morphologies. Animals with differing morphologies establish not merely different niches but different modes of living, which in the most fundamental sense means (...) establishing distinctive repertoires of movement—different ways of doing everyday things. Certain movements within one species’ repertoire may nevertheless coincide with certain movements within the repertoire of other species, as, for instance, the movement known as presenting, which occurs in multiple primate species in two different contexts: as a sexual invitation and as an aggression deterrent. That certain movements can have the same significance across species does not diminish the distinctiveness of any repertoire but attests to the evolutionary heritage of a species, namely its anchorage in morphology, that is, in bodily templates and possible variations of the same, all of which templates and possible variations translate into distinctive movement possibilities and definitive repertoires of movement.

Has science already answered the fundamental questions about the concepts of Life, Cosmos and Evolution? Has science not relegated these fundamental questions by following up on more immediate, “useful” and practical endeavors that ultimately ensure that the wheel of capitalism keeps spinning in its frantic search for material and economic progress? There is something terribly wrong with the current theory of evolution, understood as the Darwinian theory with its successive versions and extensions. The concept of natural selection, the (...) cornerstone of Darwinism, is logically inconsistent. This has been demonstrated in some of my latest academic publications. The entire conceptual framework of Darwinism is inadequate. Organisms do not compete with each other for the survival of the fittest. The fundamental relationship in Nature is not competition or confrontation, but interconnectivity, complementarity, and relational meaningfulness. A new theory of evolution is necessary to explain how it is possible that organisms as simple as bacteria, protozoa and diatoms could have generated organisms as complex as primates, and among them, the human being, a being capable of feeling and thinking, of suffering and enjoying, a being capable of having ideals and purposes. A theory that explains how it is possible that this being so complex, rich, and to some extent still unknown, has emerged from a single cell, an egg-cell, lacking all the capacities, riches and depths of human existence. Such a theory already exists. (shrink)

Numerous evolutionary linguists have indicated that human pointing behaviour might be associated with the evolution of language. At an ontogenetic level, and in normal individuals, pointing develops spontaneously and the onset of human pointing precedes as well as facilitates phases in speech and language development. Phylogenetically, pointing behaviour might have preceded and facilitated the evolutionary origin of both gestural and vocal language. Contrary to wild non-human primates, captive and human-reared nonhuman primates also demonstrate pointing behaviour. In this article, we (...) analyse the debates on pointing and its role it might have played in language evolution from a meta-level. From within an Applied Evolutionary Epistemological approach, we examine how exactly we can determine whether pointing has been a unit, a level or a mechanism in language evolution. (shrink)

Molecular clocks based upon amino acid sequences in proteins have played a major role in the clarification of evolutionary phylogenies. Creationist criticisms of these methods sometimes rely upon data that might initially seem to be paradoxical. For example, human cytochrome c differs from that of an alligator by 13 amino acids but differs by 14 amino acids from a much more closely related primate, Otolemur garnettii. The apparent anomaly is resolved by taking into consideration the variable substitution rate of (...) cytochrome c, particularly among primates. This paper traces some of the history of extensive research into the topic of rate heterogeneity in cytochrome c including data from cytochrome c pseudogenes. (shrink)

This essay examines the recent Planet of the Apes films through the lens of recent research in primatology. The films lend imaginary support to primatologist Frans de Waal’s evolutionary moral sentimentalism; however, the movies also show that truly moral motions outstrip the cognitive capacities of the great apes. The abstract moral principles employed by the ape community in the movie require the ability to understand and apply a common underlying explanation to perceptually disparate situations; in contrast, recent research in comparative (...) psychology demonstrates that the great apes lack this capacity. Since the capacity for abstraction is required on even the most basic version of moral sentimentalism—Shaun Nichols’ sentimental rules account—the lack of the capacity for abstraction reveals a qualitative distinction between primate social behavior and human morality.

The nature of human mind is a key subject for philosophy and for psychology. It is agreed that many of its characteristics and performances have been built during the last 7 million years of our primate evolution. That period began with what is called the pan-homo split, the divergence in primate evolution from the Last Common Ancestor (LCAncestor) we share with chimpanzees. The mental specificities that differentiate us from our chimpanzee cousins have been built up during (...) that time. As consequence, philosophical and psychological investigations relative to the nature of human mind should analyze that period. But this has been done only in a limited way so far. On part because the recent discipline of Evolutionary Psychology covers only a limited segment of that period and also because Husserl, the founding father of Phenomenology, took the position to not address a possible evolutionary nature of human mind (the “proscription of anthropology in Phenomenology”) [1]. We would like here to recall these limitations and introduce possible openings (this is a continuation of an already presented approach [18] [4]). Evolutionary Psychology is interested in the life and social habits of our hunter-gatherer ancestors in order to highlight mental states that were pertinent for them but do not fit with our today lives. The pre-human period considered by Evolutionary Psychology is the Pleistocene which began 2.5 million years ago. At about that time our homo-habilis ancestors were already significantly more evolved and more performant than the LCAncestor we share with chimpanzees (larger brain size, fabrication of stone tools, hands capable of precision grip, …). This means that at the beginning of the Pleistocene our ancestors were already well advanced in their evolution toward today humans. This shows that the build up of our human characteristics and specificities began before the Pleistocene, and neglecting the pre-Pleistocene time puts at risk of missing some root causes of our human specificities. This brings to consider that Evolutionary Psychology should take into account the pre-human period beginning at the pan-homo split, not only at the Pleistocene. Regarding philosophy, the proscription of anthropology in Phenomenology is currently challenged with some interest in Evolutionary Psychology [9] [8]. To avoid the risk of limiting human evolution to Pleistocene Phenomenology should explicitly plan to use anthropology on the whole evolutionary period beginning at pan-homo split. In such a perspective some help could come from an existing evolutionary scenario starting at pan-homo split and introducing a nature of self-consciousness associated to anxiety management [4]. The scenario introduces an Evolutionary Engine based on primate intersubjectivity which could have led our ancestors to build a representation of their own entity, thus leading to a natural build up of self-consciousness. Part of the scenario is also about identifications with suffering conspecifics which may have been the source of a huge anxiety, not taken into account so far and leading to an Evolutionary Anxiety intertwined with the nature of self-consciousness. It is shown that a synergy between the evolution of self-consciousness and anxiety management happened before Pleistocene, making pre-Pleistocene a key period for understanding the nature of our human minds. Overall, the scenario proposes a rationale for the pan-homo split, a tentative explanation of the divergence in pre-human primate evolution. It is also recalled that the concept of Evolutionary Anxiety makes available an entry point to the nature of human evil [14]. We present the above points and use the proposed evolutionary scenario for a reading of human evolution from last common ancestor to today humas. Continuations are introduced. (shrink)

The question about evolution of consciousness has been addressed so far as possible selectional advantage related to consciousness ("What evolutionary advantages, if any, being conscious might confer on an organism ? "). But evidencing an adaptative explanation of consciousness has proven to be very difficult. Reason for that being the complexity of consciousness. We take here a different approach on subject by looking at possible selectional advantages related to the performance of Self Awareness that appeared during evolution millions (...) of years before consciousness as we know it for humans. The interest of such an approach is that the analysis of selectional advantage is done at an evolution step sigificantly simpler that the step of Human Consciousness. We analyse how evolutionary advantages have resulted from this specific Self Awareness step. This is done by taking into consideration the possibility for a subject to identify with a conspecific at this level of evolution. We use the results made available by Mirror Neuron researchs where intersubjectivity and some level of identification with conspecifics have been evidenced for non human primates. Selectional advantages related to Self Awareness are analysed two ways: - Reformulating the performances of imitation and of development of language. - Showing that Self Awareness within group life can naturaly produce an important increase in fear/anxiety for a subject, and that the means implemented by the subject to overcome this fear/anxiety can act as significant evolution advantages opening the road to Human Consciousness. Such approach brings new elements supporting the view that consciousness is grounded in emotions. It also proposes some more evolutionist explanations to the widely dicussed subject of Empathy (S. Preston & F. de Waal) in terms of specific behaviour implemented to limit fear/anxiety increase. This approach also provides some explanation for limited anxiety within dolphins and introduces a basis for a possible phylogenesis of emotions. (shrink)

We all agree that our human minds are results of primate evolution. We humans are self conscious. The separation of our human lineage from the chimpanzee one began about 7MY ago (pan homo split). Specificities of human self consciousness have been created during that time. Besides interesting approaches differing from the one proposed here [1], little is known about how these specificities came up [2, 3]. We propose here to address that subject with an evolutionary scenario using meaningful (...) representations, identifications with conspecifics and anxiety management. Taking the beginning of the pan-homo split as a starting point we look at how an evolutionary scenario could have led to our present human self consciousness as object and as subject. An evolutionary anxiety is highlighted as having been a key contributor to the evolutionary scenario with perspectives on a possible future of self consciousness. Human self consciousness is defined here as the meaningful representation of one’s own entity, with the capability to think and talk about it. The evolutionary scenario proposed here is an extension of a previous version [11] that uses an evolution of meaningful representations introduced in previous works [8]. The scenario starts with two types of meaningful representations carried by our non self-conscious pre-human ancestors: representations of parts of themselves (seen hands, heard shouting, actions, …) and representations of conspecifics as entities existing in the environment. The next step uses elementary versions of inter-subjectivity and of identifications with conspecifics that our primate ancestors were capable of. It is proposed that these performances have brought the two types of representations to merge and bring our ancestors to progressively represent their own entity as existing in the environment like conspecifics were represented. We consider such evolutionary approach as introducing an elementary form of self consciousness as object and a s subject, both coming in together. We group them into an “ancestral self consciousness” which was to evolve into our human self consciousness [4]. Such approach avoids the need of a pre-reflective self consciousness [7]. The scenario considers that such identifications took place also with suffering or dying conspecifics. These identifications were sources of specific new fears and anxieties that the scenario groups in an “evolutionary anxiety”, source of important mental sufferings that our ancestors had to limit. Different possibilities were available for that. The scenario proposes that the chimpanzee lineage may have limited what was an unbearable mental suffering by stopping the development of identifications with conspecifics, and by this also stopping a possible evolution toward self-consciousness. This would have led to today chimpanzees. On the other side, our human lineage may have developed anxiety limitation tools like caring, pleasure, anticipation, communication and imitation; such tools also favoring the evolution of our lineage toward human minds . This is illustrated in the scenario by the introduction of an ”evolutionary engine”. In addition, the capacity for anticipation attached to self consciousness has amplified the evolutionary anxiety, leading it to become an overall “ancestral anxiety” which is still present and active in our human minds (with anxiety limitations as a key constraints to satisfy). The many anxiety limitation processes introduced in our lineage during the pan homo split were interrelated. Many came up in addition to the few ones listed here above. Most remain in our human minds at an unconscious level and are active in our everyday lives, much more than assumed so far. Considering a possible future of human self consciousness, nothing tells that human evolution is terminated. Also, the evolutionary scenario introduces the possibility for some anxiety limitation processes to be sources of evil behaviors, more precisely related to a possible pleasure procured by the suffering of others [9]. That (disturbing) background could introduce a better understanding of human mind, and so be an entry point to its future in terms of potential improvements of human nature. The scenario also introduces an evolutionary nature of reflectivity [10] which can question the philosophical need for a pre-reflective self consciousness. Such perspective can also introduce a naturalization of introspection, and then allow to consciously question the nature and content of our mental states. This could open a path for a tentative naturalization of the “what it is like” question for humans and make available an evolutionary link between self consciousness and phenomenal consciousness. A last point to highlight is that the proposed evolutionary scenario uses performances of life like intersubjectivity. This brings to note that a full understanding of the proposed scenario needs an understanding about the nature of life which is not available today. A lot remains to be done on these subjects. Continuations are introduced. (shrink)

Despite growing appreciation in recent decades of the importance of shared intentional mental states as a foundation for everything from divergences in primate evolution, to the institution of communal norms, to trends in the development of modernity as a socio-political phenomenon, we lack an adequate understanding of the relationship between individual and shared intentionality. At the same time, it is widely appreciated that deontic reasoning concerning what ought, may, and ought not be done is, like reasoning about our (...) intentions, an exercise of practical rationality. Taking advantage of this fact, I use a plan-theoretic semantics for the deontic modalities as a basis for understanding individual and shared intentions. This results in a view that accords well with what we currently have reason to believe about the phylogenetic and ontogenetic development of norm psychology and shared intentionality in human beings, and where original intentionality can be understood in terms of the shared intentionality of a community.

The ability to anticipate events, to foresight, is an adaptive advantage. We humans use it all the time. Animals have a limited access to it. Positioning foresight in human evolution is a complex subject (Suddendorf, 2013). Why and how are humans, and not chimpanzees, performant in anticipating events? We propose here to address that question with an evolutionary scenario that links self-consciousness to anxiety management (Menant, 2018). The scenario positions self-consciousness as “the capability to represent one’s own entity as (...) existing in the environment, like conspecifics are represented as existing” (making “thinking about oneself” possible). The scenario proposes that our pre-human ancestors were capable of some level of identifications with their conspecifics, and that its development has progressively brought our ancestors to represent themselves as existing in the environment like their conspecifics were represented, thus introducing self-consciousness. The scenario also proposes that identifications with suffering conspecifics have been the source of an important anxiety that had to be limited for evolution to continue. Some of our ancestors have not been able to limit that new anxiety. Their mental pain became unbearable. Their evolution was almost stopped, thus initiating the pan-homo split. Developing an ability to anticipate events has been a key contributor to anxiety limitation by providing information about the sufferings to come, and consequently allowing to limit and avoid them. In addition to that role of foresight in human evolution it is worth noticing that the associated chaining of mental events brings to propose foresight as an entry point to the concept of causality in human evolution. Regarding our chimpanzee cousins, the pan-homo split in the scenario positions them as not self-conscious, not capable of anticipation like humans are, and less anxious than humans. Continuations are proposed. (shrink)

We humans experience ourselves as objects and as subjects. The distinction initiated by Kant between consciousness of oneself as object and consciousness of oneself as subject was a strict one. The rigidity of that distinction has been challenged by philosophers from the continental and the analytic traditions [1]. From another perspective, researches about animal self-awareness are widening the horizon of studies relative to the nature of self-consciousness [2]. These various perspectives introduce the interest about addressing consciousness of oneself as object (...) and as subject in an evolutionary background. We propose here to follow that path by using an existing scenario about the evolutionary nature of self-consciousness based on evolutions of representations and of inter-subjectivity [3, 4]. The scenario presents an evolutionary approach that can introduce self-consciousness as an acting body and self-consciousness as a thinking and feeling entity. These two aspects of self-consciousness are then compared to consciousness of oneself as object and as subject. The scenario proposes that an evolution of inter-subjectivity brought our pre-human ancestors to reach the capability of identifying with their conspecifics. This process coupled with an evolution of representations led our ancestors to build up representations of themselves as entities existing in the environment, like the conspecifics they identified with were represented. As conspecifics were perceived as existing and acting in the environment, identifying with them led to an elementary version of self-consciousness as an acting body, close to self-consciousness as object. Also, as different conspecifics could display very different behaviors like dominant or submitted, it was not possible to identify with them spontaneously. Knowing and understanding one's own identity as perceived by other members of the group was necessary for a pertinent identification with conspecifics. Such need to think about one's own characteristics and identity introduced self-consciousness as a thinking and feeling entity, close to an elementary version of self-consciousness as subject. In addition, the mental states of the thinking and feeling subject monitoring the actions of the body object address the common evolutionary source for consciousness of oneself as object and as subject. We present here that evolutionary approach to consciousness of oneself as object and as subject with the corresponding phylogenetic outcomes relative to the mind-body problem. Continuations are proposed. (shrink)

Anxiety is a main contributor to human psychological sufferings. Its evolutionary sources are generally related to alert signals for coping with adverse or unexpected situations [Steiner, 2002] or to hunter-gatherer emotions mismatched with today environments [Horwitz & Wakefield, 2012]. We propose here another evolutionary perspective that links human anxiety to an evolutionary nature of self-consciousness. That approach introduces new relations between mental health and human mind. The proposed evolutionary scenario starts with the performance of primate identification with conspecifics [de (...) Waal 1998, 2008]. It is assumed that the evolution of that identification brought our ancestors to represent themselves as entities existing in the environment, like conspecifics were represented as existing in the environment. We consider that this process has implemented in the mind of our ancestors some first elements of self-consciousness [Menant 2014a]. But the same process has also produced new sufferings coming from identification with suffering or endangered conspecifics. In addition, the emerging performance of self-focus brought in the new feeling of being a suffering entity. We consider that all these new sufferings have created in the mind of our primate ancestors a huge anxiety increase, unbearable if not limited. Among the options available to limit that anxiety increase we focus on two of them that may have taken place. The first was a withdrawal from the process. Some primates may have simply rejected the evolution of identification (and with it self-consciousness). This may have led them to an ecological niche resulting in our today great apes. The second option was about limiting the causes of sufferings and taking advantage of possible resulting evolutionary benefits. This may have been achieved by developing performances like imitation, communication, simulation, synergy and ToM. Added to a positive feedback on identification these performances may have initiated an evolutionary engine that has accelerated the evolution toward human self-consciousness. That option is characterized by an early build up of anxiety limitation processes in an evolutionary nature of our human self-consciousness. This option corresponds to a human specificity and introduces anxiety management and self-consciousness as sharing a same evolutionary story. The build up of these anxiety management processes is now buried in the evolutiony story of our human mind. But these processes are still present in our minds at an unconscious level and participate to many of our human mental states and behaviors. Such positioning of anxiety management as part of the nature of human mind is new and makes available entry points for new understandings of human emotion, motivations and mental disorders. The proposed evolutionary scenario has been introduced in philosophy of mind [Menant 2011, 2014a, b] but it has not been so far explicitly part of primatology nor of psychology/psychiatry/ethics. We present here a drawing of the scenario with highlights on corresponding key points. More work is needed on these new evolutionary links between human mind and anxiety management.

Humans leverage material forms for unique cognitive purposes: We recruit and incorporate them into our cognitive system, exploit them to accumulate and distribute cognitive effort, and use them to recreate phenotypic change in new individuals and generations. These purposes are exemplified by writing, a relatively recent tool that has become highly adept at eliciting specific psychological and behavioral responses in its users, capability it achieved by changing in ways that facilitated, accumulated, and distributed incremental behavioral and psychological change between individuals (...) and generations. Writing is described here as a self-organizing system whose design features reflect points of maximal usefulness that emerged under sustained collective use of the tool. Such self-organization may hold insights applicable to human cognitive evolution and tool use more generally. Accordingly, this article examines the emergence of the ability to leverage material forms for cognitive purposes, using the tool-using behaviors and lithic technologies of ancestral species and contemporary non-human primates as proxies for matters like collective use, generational sustainment, and the non-teleological emergence of design features.

Researchers have converged on the idea that a pragmatic understanding of communication can shed important light on the evolution of language. Accordingly, animal communication scientists have been keen to adopt insights from pragmatics research. Some authors couple their appeal to pragmatic aspects of communication with the claim that there are fundamental asymmetries between signalers and receivers in non-human animals. For example, in the case of primate vocal calls, signalers are said to produce signals unintentionally and mindlessly, whereas receivers (...) are thought to engage in contextual interpretation to derive the significance of signals. We argue that claims about signaler-receiver asymmetries are often confused. This is partly because their authors conflate two conceptions of pragmatics, which generate different accounts of the explanatory target for accounts of the evolution of language. Here we distinguish these conceptions, in order to help specify more precisely the proper explanatory target for language evolution research. (shrink)

It is pretty obvious that language and human consciousness entertain tight relations. We could not really be conscious of ourselves without the possibility to say “I” or “me”. And language is a key contributor in our capability to identify ourselves as conscious entities existing in the environment. But the relations linking language and consciousness are complex and difficult to analyze. Evolutionary origins of language are unknown as no fossil traces have been left by our ancestors. Sciences of consciousness however begin (...) to make available some possible evolutionary scenarios about the nature of human consciousness. We want here to propose a link between language and consciousness by using such an evolutionary scenario and also introduce the usage of a systemic approach to meaning generation. In the first part of the presentation we will use an existing scenario about the evolutionary nature of self-consciousness where the development of language has a role (1). We will highlight this role in order to identify language and self-consciousness as inter-dependant in their nature through a possible common evolutionary origin. Self-consciousness and language could then be considered as tightly inter-dependant through a common build up of human nature during evolution. The scenario presents an evolutionary nature of self-consciousness as resulting of the capability for pre-human primates to identify with their conspecifics (1, 2). The conspecifics are represented as existing in the environment, and such identification brought our pre-human ancestors to consider themselves as also existing in the environment. The scenario takes this event as being a first step for a conscious self-representation within pre-human primates, which progressively evolved toward our today human consciousness (3). But such identification with conspecifics was not for free at times of survival of the fittest. Identifying with conspecifics meant for our pre-human ancestor to also identify with their sufferings or encountered dangers. These came in addition to the dangers or sufferings naturally encountered and created a significant anxiety increase (1). The resulting level of anxiety had to be limited. One possibility for that was to develop psychological or physical tools that could have reduced the risks of occurrences and developments of such dangers and sufferings. Among these tools is the performance of language which can induce significant evolutionary advantages. We will propose a first scheme about how these evolutionary advantages could have reduced the dangers and sufferings encountered by our pre-human ancestors. We will also show how the development of language produced by itself a positive feedback on the development of inter-subjectivity in the evolutionary scenario, and so participated directly to the development of human consciousness. Other evolutionary advantages have existed like the development of imitation and synergy through experience (4). Language played a role there also, and has to be taken into account. The second part of the presentation will propose the usage of an existing systemic approach to meaning generation in terms of constraints satisfaction (5, 6). Constraints for pre-human primates, ranging from a basic “stay alive” to highly elaborated “limit anxiety”, were source of multiple meaning generations in which language has played (and still plays) a key role. Several continuations will be proposed linked to the here above thread on a co-evolutions of language and human consciousness, as based on the evolutionary scenario. (shrink)

Combinatorial behavior involves combining different elements into larger aggregates with meaning. It is generally contrasted with compositionality, which involves the combining of meaningful elements into larger constituents whose meaning is derived from its component parts. Combinatoriality is commonly considered a capacity found in primates and other animals, whereas compositionality often is considered uniquely human. Questioning the validity of this claim, this multidisciplinary special issue of the International Journal of Primatology unites papers that each study aspects of combinatoriality and compositionality found (...) in primate and bird communication systems, tool use, skills, and human language. The majority of authors conclude that compositionality is evolutionarily preceded by combinatoriality and that neither are uniquely human. This introduction briefly introduces readers to the major findings and issues raised by the contributors. -/- . (shrink)

In this article, I advance a novel hypothesis on the evolution of hominin bipedalism. I begin by arguing extensively for how the transition to bipedalism must have been problematic for hominins during the Neogene. Due to this and the fact that no other primate has made the unusual switch to bipedalism, it seems likely that the selection pressure towards bipedalism was unusually strong. With this in mind, I briefly lay out some of the most promising hypotheses on the (...) evolutionary origin of hominin bipedalism and show how most, if not all, fail in the face of the need for an unusually strong selection pressure. For example, some hypotheses maintain that hominins became bipedal so they could use their hands for carrying infants, food, or other valuable objects. But extant apes are able to carry objects in one of their front limbs (while walking with the other three), and thus it does not seem plausible that our hominin ancestors went through the troublesome transition to bipedalism just so they could carry objects a little more efficiently. After I show that past hypotheses are wanting in the face of this challenge, I argue that there is only one selection pressure powerful enough to instigate a strange and problematic evolutionary adaptation like bipedalism, and that is sexual selection. Specifically, from the fact that bipedal locomotion is an important strategy for intimidating others and ascending the dominance hierarchy in extant apes, I argue that for no particular selective reason bipedal locomotion became a signal for high fitness (much as a large and intricate tail became a signal for high fitness for peahens), and this led to the trait being continuously reinforced in spite of all its deleterious fitness consequences.

Music and language are universal human abilities with many apparent similarities relating to their acoustics, structure, and frequent use in social situations. We might therefore expect them to be understood and processed similarly, and indeed an emerging body of research suggests that this is the case. But the focus has historically been on the individual, looking at the passive listener or the isolated speaker or performer, even though social interaction is the primary site of use for both domains. Nonetheless, an (...) important goal of emerging research is to compare music and language in terms of acoustics and structure, social interaction, and functional origins to develop parallel accounts across the two domains. Indeed, a central aim of both of evolutionary musicology and language evolution research is to understand the adaptive significance or functional origin of human music and language. An influential proposal to emerge in recent years has been referred to as the social bonding hypothesis. Here, within a comparative approach to animal communication systems, I review empirical studies in support of the social bonding hypothesis in humans, non-human primates, songbirds, and various other mammals. In support of this hypothesis, I review six research fields: (i) the functional origins of music; (ii) the functional origins of language; (iii) mechanisms of social synchrony for human social bonding; (iv) language and social bonding in humans; (v) music and social bonding in humans; and (vi) pitch, tone and emotional expression in human speech and music. I conclude that the comparative study of complex vocalizations and behaviors in various extant species can provide important insights into the adaptive function(s) of these traits in these species, as well as offer evidence-based speculations for the existence of “musilanguage” in our primate ancestors, and thus inform our understanding of the biology and evolution of human music and language.

It is pretty obvious to most of us that self-consciousness is a product of evolution. But its nature is unknown. We propose here a scenario addressing a possible evolutionary nature of self-consciousness covering the segment linking pre-human primates to humans. The scenario is based on evolutions of representations and of inter-subjectivity that could have taken place within the minds of our pre-human ancestors . We begin by situating self-consciousness relatively to other aspects of human consciousness. With the help of (...) anthropology, we date a possible starting point of our scenario at a time when our non self-conscious pre-human ancestors were able to build meaningful representations and were capable of inter-subjectivity, like are our today modern apes. As the proposed scenario is based on an evolution of representations, we recall an existing model for meaningful representations based on the generation of meaningful information by systems submitted to internal constraints. This model allows us to define representations of conspecifics and auto-representations that we assume as having been present in the minds of our pre-human ancestors. The next step of the scenario is to consider an evolution of inter-subjectivity towards identification with conspecifics that could have led to a merger of the auto-representation with the representations of conspecifics in the minds of our ancestors. Such a merger brought the auto-representation to become about an entity existing in the environment, as were the representations of conspecifics. We consider that such identification with conspecifics has introduced in the mind of our ancestors an elementary and embryonic sense of being an existing entity that we name ‘ancestral self-consciousness’. The same process has also imposed to our ancestors an identification with suffering or endangered conspecifics which has produced an important anxiety increase that could have blocked the evolutionary process. We propose that the performances developed by our ancestors to manage that anxiety increase have also generated significant evolutionary advantages that have helped the development of ancestral self-consciousness and favored its evolution toward our full-fledged self-consciousness. It is also proposed that some pre-human primates have avoided the anxiety increase by finding a niche where evolutionary advantages were not necessary. This may have led to our today apes. The contribution of anxiety to the proposed scenario brings to position anxiety management as having guided the evolution of self-consciousness and as still being a key player in our today human minds. Regarding philosophy of mind, possible links between phenomenal consciousness and the proposed nature of self-consciousness are introduced. The conclusion presents a summary of the points addressed here. Possible continuations are highlighted as related to human mind, to anxiety management and to artificial intelligence. (shrink)

How The Evolution Of Language Created The Mysteries of Subjective Experience, Mind And Self. -/- In this new paradigm, a distinction is made between biological awareness which exists in varying degrees in all animate beings and consciousness, the origin of which is based on symbolic language and therefore found only within our species. The evolution of language enabled us to not only label and communicate our experiences, an ability shared by other primates but to also describe and explain (...) them, both of which only humans are capable. The essence of the mind-body problem has been our inability to explain how our inner subjective experiences became seen as different from our objective experiences of the physical world. This problematic duality was created by the relatively rapid growth in scientific terminology and thought during the seventeenth century which was in sharp contrast to our emotionally based vocabulary. As we became increasingly tuned into the physical world, our awareness of the difference between our objective and subjective experiences became obvious. As the evolution of language further enabled us to label and describe both our objective and subjective experiences, we were able to recognize the difference between what was occurring within us versus to us. This naturally created the dualism of mind versus body. The evolution of symbolic language was not only the basis for both the origin of consciousness and the mind-body problem, but for the metaphysical ideas of god and mind as well as of the soul and the personal self. As such, this book provides an entirely new perspective on subjects that have long perplexed many thinkers throughout history. (shrink)

Scholarly opinions vary on what language is, how it evolved, and from where or what it evolved. Long considered uniquely human, today scholars argue for evolutionary continuity between human language and animal communication systems. But while it is generally recognized that language is an evolving communication system, scholars continue to debate from which species language evolved, and what behavioral and cognitive features are the precursors to human language. To understand the nature of protolanguage, some look for homologs in gene functionality, (...) brain areas, or anatomical structures such as the supralaryngeal vocal tract; others point toward primates, their gestural, vocal, multimodal, and in later evolving hominins also their pantomimic communication systems; and still others draw parallels between the musicality that characterizes language and the pitch found in the numerous sounds produced by animals. Accordingly, protolanguage theories today are multiple and diverse, and protolanguages might have also been diverse. This special issue on Evolving (Proto)Language/s for Lingua bundles several of the protolanguage theories that were put forward at the sixth edition of the Ways to Protolanguage conference series, held at the Calouste Gulbenkian Foundation in Lisbon, in 2019. Not aimed at surveying all the different ways there are to conceptualize, study, and model protolanguage/s, this issue provides interested readers with good overviews on the role played in current theorizing on protolanguage/s by (paleo)anthropology, genetics, physiology, developmental, evolutionary, ecological, and pragmatic research lines.

Recent discussions of animal communication and the evolution of language have advocated adopting a ‘pragmatics-first’ approach, according to which “a more productive framework” for primate communication research should be “pragmatics, the field of linguistics that examines the role of context in shaping the meaning of linguistic utterances”. After distinguishing two different conceptions of pragmatics that advocates of the pragmatics-first approach have implicitly relied on, I argue that neither conception adequately serves the purposes of pragmatics-first approaches to the origins (...) of human linguistic communication. My main aim in this paper is to motivate–and begin to articulate–an intermediary conception whose scope is narrower than Carnapian pragmatics but broader than Gricean pragmatics. To do so, I first spell out what I take to be the key insight offered by proponents of the Gricean approach concerning the emergence of linguistic communication, namely, its being communication ‘from a psychological point of view’. I then develop this insight using key elements from the anti-Gricean ‘biosemantic’ account of linguistic communication due to Ruth Millikan, Philosophical Perspectives 9, Ridgeview Publishing, Atascedero CA, 1995, Millikan R Varieties of Meaning. Mass.: The MIT Press, Cambridge, Millikan, Beyond concepts: unicepts, language, and natural information, Oxford University Press, Oxford UK, 2017, and elsewhere). I argue that the intermediary pragmatics-first approach that I propose, which draws on both Gricean and Millikanian resources, would be better equipped to serve the purposes of those who search for potential precursors of human linguistic communication in animal communication.

The term “deep history” refers to historical accounts framed temporally not by the advent of a written record but by evolutionary events (Smail 2008; Shryock and Smail 2011). The presumption of deep history is that the events of today have a history that traces back beyond written history to events in the evolutionary past. For human kinship, though, even forming a history of kinship, let alone a deep history, remains problematic, given limited, relevant data (Trautman et al. 2011). With regard (...) to a deep history, one conjecture is that human kinship evolved from primate social systems in a gradual, more-or-less continuous manner (see Chapais 2008); another conjecture is that kinship, in accordance with the incest account of Claude Lévi-Strauss (1969) or the fanciful, tetradic account of Nicholas J. Allen (1986), “comes into existence with a leap” (Trautman et al. 2011: 176); and yet another, the account to be developed in this paper, is that kinship, as it is understood and lived by culture bearers today, is the consequence of a profound and qualitative evolutionary transformation going from an ancestral primate-like social system predicated on extensive face-to-face interaction to the relation-based social systems that characterize human societies (Read 2012).

The visuospatial system integrates inner and outer functional processes, organizing spatial, temporal, and social interactions between the brain, body, and environment. These processes involve sensorimotor networks like the eye–hand circuit, which is especially important to primates, given their reliance on vision and touch as primary sensory modalities and the use of the hands in social and environmental interactions. At the same time, visuospatial cognition is intimately connected with memory, self-awareness, and simulation capacity. In the present article, we review issues associated (...) with investigating visuospatial integration in extinct human groups through the use of anatomical and behavioral data gleaned from the paleontological and archaeological records. In modern humans, paleoneurological analyses have demonstrated noticeable and unique morphological changes in the parietal cortex, a region crucial to visuospatial management. Archaeological data provides information on hand–tool interaction, the spatial behavior of past populations, and their interaction with the environment. Visuospatial integration may represent a critical bridge between extended cognition, self-awareness, and social perception. As such, visuospatial functions are relevant to the hypothesis that human evolution is characterized by changes in brain–body–environment interactions and relations, which enhance integration between internal and external cognitive components through neural plasticity and the development of a specialized embodiment capacity. We therefore advocate the investigation of visuospatial functions in past populations through the paleoneurological study of anatomical elements and archaeological analysis of visuospatial behaviors.

This paper considers the question of whether chimpanzees possess at least a primitive sense of normativity: i.e., some ability to internalize and enforce social norms—rules governing appropriate and inappropriate behaviour—within their social groups, and to make evaluations of others’ behaviour in light of such norms. A number of scientists and philosophers have argued that such a sense of normativity does exist in chimpanzees and in several other non-human primate and mammalian species. However, the dominant view in the scientific and (...) philosophical literature is that psychological capacities for social norms evolved uniquely in the human lineage, after our last common ancestor with chimpanzees and bonobos. After reviewing some of the existing evidence for normative capacity in chimpanzees, I defend the thesis of chimpanzee normativity against three key theoretical objections that have been presented in the literature, each of which have played a part in motivating the dominant sceptical position. I argue that, while we still have much to learn about the nature and extent of the normative capacities of other animals, there is strong prima facie evidence for social norms and normative evaluation in chimpanzees and the main theoretical objections to chimpanzee normativity are not at all compelling.

With an extensive amount of research on the social lives of primates, Frans de Waal has been a pioneering advocate for the continuity of human and non-human minds, putting forward the idea that these creatures exhibit rudimentary political and moral behaviors. One of the traits which de Waal focuses on is animal normativity, a set of behaviors functionally defined as adherence to social standards. Recently, some philosophers have endorsed this position, holding that animals show a psychological capacity called normative cognition (...) underlying those and other social behaviors. In this paper, I assess whether advocacy for animal normativity is an exercise of theory construction in comparative cognition. To that end, I present three features of this kind of theory construction. First, the explanatory goal of building functional analyses of cognitive capacities. Second, the conceptual aid of comparative thinking for theory construction. Third, the heuristic value of theory in specifying possible roads of inquiry. Taking these features into account, I assess whether the claims advocates make regarding animal normativity consider them. My answer is negative. First, since some advocates focus on behavioral traits and not on psychological capacities, they are not producing theory in comparative cognition, although, as I argue, they should. Second, there is a disregard for hypothesis testing and no evolutionary considerations to support their views. Finally, the claim that non-human animals exhibit normativity does not seem to have heuristic value. (shrink)

Colour information not only helps sustain the survival of animal species by guiding sexual selection and foraging behaviour but also is an important factor in the cultural and technological development of our own species. This is illustrated by examples from the visual arts and from state-of-the-art imaging technology, where the strategic use of colour has become a powerful tool for guiding the planning and execution of interventional procedures. The functional role of colour information in terms of its potential benefits to (...) behavioural success across the species is addressed in the introduction here to clarify why colour perception may have evolved to generate behavioural success. It is argued that evolutionary and environmental pressures influence not only colour trait production in the different species but also their ability to process and exploit colour information for goal-specific purposes. We then leap straight to the human primate with insight from current research on the facilitating role of colour cues on performance training with precision technology for image-guided surgical planning and intervention. It is shown that local colour cues in two-dimensional images generated by a surgical fisheye camera help individuals become more precise rapidly across a limited number of trial sets in simulator training for specific manual gestures with a tool. This facilitating effect of a local colour cue on performance evolution in a video-controlled simulator (pick-and-place) task can be explained in terms of colour-based figure-ground segregation facilitating attention to local image parts when more than two layers of subjective surface depth are present, as in all natural and surgical images.

Empirical studies of the social lives of non-human primates, cetaceans, and other social animals have prompted scientists and philosophers to debate the question of whether morality and moral cognition exists in non-human animals. Some researchers have argued that morality does exist in several animal species, others that these species may possess various evolutionary building blocks or precursors to morality, but not quite the genuine article, while some have argued that nothing remotely resembling morality can be found in any non-human species. (...) However, these different positions on animal morality generally appear to be motivated more by different conceptions of how the term “morality” is to be defined than by empirical disagreements about animal social behaviour and psychology. After delving deeper into the goals and methodologies of various of the protagonists, I argue that, despite appearances, there are actually two importantly distinct debates over animal morality going on, corresponding to two quite different ways of thinking about what it is to define “morality”, “moral cognition”, and associated notions. Several apparent skirmishes in the literature are thus cases of researchers simply talking past each other. I then focus on what I take to be the core debate over animal morality, which is concerned with understanding the nature and phylogenetic distribution of morality conceived as a psychological natural kind. I argue that this debate is in fact largely terminological and non-substantive. Finally, I reflect on how this core debate might best be re-framed. (shrink)

Evolutionary advantages of consciousness and intersubjectivity are part of current philosophical debates on the nature of consciousness. Both are linked and intersubjectivity is sometimes considered as a form of consciousness [1]. Regarding the evolution of consciousness, studies tend to focus on phenomenal consciousness [2]. We would like here to bring the focus on self-consciousness and continue the build up of a corresponding evolutionary scenario. We also propose to introduce a possible evolutionary link between self-consciousness and phenomenal consciousness. Our starting (...) point is the evolutionary scenario based on the evolution of intersubjectivity that goes thru the identification with conspecifics at pre-human primate time frame [3, 4, 5]. The scenario considers that such identification with conspecifics brought the non self-conscious auto-representation carried by our prehuman primate ancestors to merge with the representations of conspecifics. The latter transferred to the auto-representation the characteristics of an entity existing in the environment, and by this way introduced some first elements of self-consciousness for our pre-human ancestors. In addition, an anxiety increase coming from the identification with suffering or endangered conspecifics produced an evolutionary engine based on anxiety limitation. We want here to complement this evolutionary approach by introducing the improvement of action programs as a contributor to the evolutionary advantages of intersubjectivity and self-consciousness. We look at the possibility for a subject to improve the action programs that conspecifics implement. The performance of identification with conspecifics allows the subject to consider that errors made by conspecifics are potentially her own errors, and consequently allows the subject to correct the errors of conspecifics for her own benefit. We describe the process of non successful action identification from the perspective of an observer and present the synergetic action program improvements with their contribution to the evolution of intersubjectivity and self-consciousness. We add this contribution to the existing evolutionary scenario on self-consciousness and introduce a possible evolutionary link between self-consciousness and phenomenal consciousness. We use for that the relation existing between phenomenal consciousness and pre-reflexive self-consciousness [6] and propose to link the latter to the proposed evolutionary nature of self-consciousness. We finish by summarizing the points addressed and by introducing some possible continuations. (shrink)

Modern selfhood presents itself as autonomous, overcoming emotion by following cognitive, moral and linguistic norms on the basis of clear, rational principles. It is difficult to imagine how such normative creatures could have evolved from their purely biological, non-normative, primate ancestors. I offer a just-so story to make it easier to imagine this transition. Early hominins learned to cooperate by developing group identities based on tribal norms. Group identity constituted proto-selves as normative creatures. Such group identity was not based (...) on autonomous selfhood – such an explanation would be anachronistic -- but on emotional patterning. By imitation, music, dance, ritual and other emotional practices, proto-selves learned how to bind themselves to the norms of their culture. Such conformity was a transitional evolutionary stage between primates and selves. Emotion and rationality are not incompatible: even contemporary selfhood remains rooted in emotional identity.

To naturalize religion, we must identify what religion is, and what aspects of it we are trying to explain. In this paper, religious social institutional behavior is the explanatory target, and an explanatory hypothesis based on shared primate social dominance psychology is given. The argument is that various religious features, including the high status afforded the religious, and the high status afforded to deities, are an expression of this social dominance psychology in a context for which it did not (...) evolve: high-density populations made possible by agriculture.

Current research on the origin of DNA and RNA, viruses, and mobile genetic elements prompts a re-evaluation of the origin and nature of genetic material as the driving force behind evolutionary novelty. While scholars used to think that novel features resulted from random genetic mutations of an individual’s specific genome, today we recognize the important role that acquired viruses and mobile genetic elements have played in introducing evolutionary novelty within the genomes of species. Viral infections and subviral RNAs can enter (...) the host genome and persist as genetic regulatory networks. Persistent viral infections are also important to understand the split between great apes and humans. Nearly all mammals and nonhuman primates rely on olfaction, i.e., chemoreception as the basis of the sense of smell for social recognition, group membership, and the coordination of organized social life. Humans, however, evolved other means to establish social bonding, because several infection waves by endogenous retroviruses caused a loss of odor receptors in human ancestors. The human independence from olfaction for social recognition was in turn one driver of the rather abrupt human transition to dependence on visual information, gesture production, and facial recognition that are at the roots of language-based communication.

I review recent work from armchair and cross-cultural epistemology on whether humans possess a knowledge concept as part of a universal “folk epistemology.” The work from armchair epistemology fails because it mischaracterizes ordinary knowledge judgments. The work from cross-cultural epistemology provides some defeasible evidence for a universal folk epistemology. I argue that recent findings from comparative psychology establish that humans possess a species-typical knowledge concept. More specifically, recent work shows that knowledge attributions are a central part of primate social (...) cognition, used to predict others’ behavior and guide decision-making. The core primate knowledge concept is that of truth detection (across different sensory modalities) and retention (through memory) and may also include rudimentary forms of indirect truth discovery through inference. In virtue of their evolutionary heritage, humans inherited the primate social-cognitive system and thus share this core knowledge concept. (shrink)

The last decades have seen major advances in the study of gestures both in humans and non-human primates. In this paper, we seriously examine the idea that there may be gestural form types that are shared across great ape species, including humans, which may underlie gestural universals, both in form and meaning. We focus on one case study, the hand fling gesture common to chimpanzees and humans, and provide a semantic analysis of this gesture.
