Although pantomimic scenarios recur in the most important historical as well as current accounts of language origins, a serious problem is the lack of a commonly accepted definition of “pantomime”. We scrutinise several areas of study, from theatre studies to semiotics to primatology, pointing to the differences in use that may give rise to misunderstandings, and working towards a set of definitional criteria of “pantomime” specifically useful for language evolution research. We arrive at a definition of pantomime as a communication (...) mode that is mimetic; non-conventional and motivated; multimodal ; improvised; using the whole body rather than exclusively manual; holistic; communicatively complex and self-sufficient; semantically complex; displaced, open-ended and universal. So conceived, “pantomime” is a near synonym of “bodily-mimetic communication” as envisaged by Donald and Zlatev. On a wider plane, our work may help organise some of the terminology and discussion in language evolution, e.g. by drawing a clear distinction between gestural and pantomimic scenarios or by specifying the relation between pantomimic and multimodal scenarios.

A persistent controversy in language evolution research has been whether language emerged in the gestural-visual or in the vocal-auditory modality. A “dialectic” solution to this age-old debate has now been gaining ground: language was fully multimodal from the start and remains so to this day. In this paper, we show this solution to be too simplistic and outline a more specific theoretical proposal, which we designate as pantomime-first. To decide between the multimodal-first and pantomime-first alternatives, we review several lines of (...) interdisciplinary evidence and complement it with a cognitive-semiotic experiment. In the study, the participants saw – and then matched to hand-drawn images – recordings of short transitive events enacted by 4 actors in two conditions: visual and multimodal. Significantly, the matching accuracy was greater in the visual than the multimodal condition, though a follow-up experiment revealed that the emotional profiles of the events enacted in the multimodal condition could be reliably detected from the sound alone. We see these results as supporting the proposed pantomime-first scenario. (shrink)

In this paper, we complement proximate or ‘how’ explanations for the origins of language, broadening our perspective to include fitness-consequences explanations, i.e. ultimate, or ‘why’ explanations. We identify the platform of trust as a fundamental prerequisite for the development of a language-like system of symbolic communication. The platform of trust is a social niche in which cheap but honest communication with non-kin is possible, because messages tend to be trusted as a default. We briefly consider the place of the platform (...) of trust on the road map as laid out in the Mirror System Hypothesis. We then turn to recent research on turn-taking in primates, which has been proposed as a precursor of the cooperative structuring of conversation in humans. We suggest, instead, that human turn-taking, in its full richness that makes it an interesting explanatory target, may only appear in a communicative system that is already founded on a community-wide, cooperative platform of trust.

Gestural and pantomimic accounts of language origins propose that language did not develop directly from ape vocalisations, but rather that its emergence was preceded by an intervening stage of bodily-visual communication, during which our ancestors communicated with their hands, arms, and the entire body. Gestural and pantomimic scenarios are again becoming popular in language evolution research, but this line of thought has a long and interesting history that gained special prominence in the Enlightenment, often considered the golden age of glottogony. (...) We highlight several themes key to this line of reflection, such as the idea of innate communication that consists of visual bodily signs and non-linguistic vocalisations; the division of labour between these two semiotic resources ; or the developmental trajectory of this bi-modal system of communication determined by its transmission through generations of users and the intervention of social factors. We confront these ideas with problems discussed in current language evolution research, focusing on polysemioticity, sign function, conventionality and modality transition. (shrink)

The set of design features developed by Charles Hockett in the 1950s and 1960s remains probably the most influential means of juxtaposing animal communication with human language. However, the general theoretical perspective of Hockett is largely incompatible with that of modern language evolution research. Consequently, we argue that his classificatory system—while useful for some descriptive purposes—is of very limited use as a theoretical framework for evolutionary linguistics. We see this incompatibility as related to the ontology of language, i.e. deriving from (...) Hockett’s interest in language as a product rather than a suite of sensorimotor, cognitive and social abilities that enable the use but also acquisition of language by biological creatures. After a reconstruction of Hockett’s views on design features, we raise two criticisms: focus on the means at the expense of content and focus on the code itself rather than the cognitive abilities of its users. Finally, referring to empirical data, we illustrate some of the problems resulting from Hockett’s approach by addressing three specific points—namely arbitrariness and semanticity, cultural transmission, and displacement—and show how the change of perspective allows to overcome those difficulties.

We present a new road map for research on “How the Brain Got Language” that adopts an EvoDevoSocio perspective and highlights comparative neuroprimatology – the comparative study of brain, behavior and communication in extant monkeys and great apes – as providing a key grounding for hypotheses on the last common ancestor of humans and monkeys and chimpanzees and the processes which guided the evolution LCA-m → LCA-c → protohumans → H. sapiens. Such research constrains and is constrained by analysis of (...) the subsequent, primarily cultural, evolution of H. sapiens which yielded cultures involving the rich use of language. (shrink)

Politeness in conversation is a fascinating aspect of human interaction that directly interfaces language use and human social behavior more generally. We show how game theory, as a higher-order theory of behavior, can provide the tools to understand and model polite behavior. The recently proposed responsibility exchange theory :313–344, 2019) describes how the polite communications of thanking and apologizing impact two different types of an agent’s social image: warmth and competence. Here, we extend this approach in several ways, most importantly (...) by adding a cultural-evolutionary dynamics that makes it possible to investigate the evolutionary stability of politeness strategies. Our analysis shows that in a society of agents who value status-related traits over reciprocity-related traits, both the less and the more polite strategies are maintained in cycles of cultural-evolutionary change.

We applaud Heintz & Scott-Phillips's guiding metaphor of “unleashing leashed expression,” and we value the unified explanation for the emergence of not only language, but also other forms of unleashed expression, such as multimodal communication. We are more critical of the authors' discussion of the selection pressures acting towards unleashed expression, which are proposed to hinge on partner choice ecology.

Experimental Semiotics (ES) is the study of novel forms of communication that communicators develop in laboratory tasks whose designs prevent them from using language. Thus, ES relates to pragmatics in a “pure,” radical sense, capturing the process of creating the relation between signs and their interpreters as biological, psychological, and social agents. Since such a creation of meaning-making from scratch is of central importance to language evolution research, ES has become the most prolific experimental approach in this field of research. (...) In our paper, we report the results of a study on the scope of recent ES and evaluate the ways in which it is relevant to the study of language origins. We coded for multiple levels across 13 dimensions related to the properties of the emergent communication systems or properties of the study designs, such as type of goal (coordination versus referential), modality of communication, absence or presence of turn-taking, or the presence of vertical vs. horizontal transmission. We discuss our findings and our classification, focusing on the advantages and limitations of those trends in ES, and in particular their ecological validity in the context of bootstrapping communication and the evolution of language.

Several lines of research within developmental psychology, experimental semiotics and language origins studies have recently converged in their interest in pantomime as a system of bodily communication distinct from both language (spoken or signed) and nonlinguistic gesticulation. These approaches underscore the effectiveness of pantomime, which despite lack of semiotic conventions is capable of communicating complex meanings. However, very little research is available on the structural underpinnings of this effectiveness, that is, the specific properties of pantomime that determine its communicative success. (...) To help fill in this gap, we conducted an exploratory rating study aimed at identifying those properties of pantomime that facilitate its understanding. We analysed an existing corpus of 602 recordings of whole-body re-enactments of short transitive events, coding each of them for 6 properties, and found out that the presence of salient elements (conspicuous objects in a specific semantic space), image mapping (representing the physical orientation of the object), and gender markers (distinguishing between the represented characters) increased the guessability of pantomimes.
