Biological Capacity

Human language is unique among the communication systems of the natural world: it is socially learned and, as a consequence of its recursively compositional structure, offers open-ended communicative potential. The structure of this communication system can be explained as a consequence of the evolution of the human biological capacity for language or the cultural evolution of language itself. We argue, supported by a formal model, that an explanatory account that involves some role for cultural evolution has profound implications for our understanding of the biological evolution of the language faculty: under a number of reasonable scenarios, cultural evolution can shield the language faculty from selection, such that strongly constraining language-specific learning biases are unlikely to evolve. We therefore argue that language is best seen as a consequence of cultural evolution in populations with a weak and/or domain-general language faculty.

Precise Relationship

Recent work suggests that linguistic structure develops through cultural evolution, as a consequence of the repeated cycle of learning and use by which languages persist. This work has important implications for our understanding of the evolution of the cognitive basis for language: in particular, human language and the cognitive capacities underpinning it are likely to have been shaped by co-evolutionary processes, where the cultural evolution of linguistic systems is shaped by and in turn shapes the biological evolution of the capacities underpinning language learning. I review several models of this co-evolutionary process, which suggest that the precise relationship between evolved biases in individuals and the structure of linguistic systems depends on the extent to which cultural evolution masks or unmasks individual-level cognitive biases from selection. I finish by discussing how these co-evolutionary models might be extended to cases where the biases involved in learning are themselves shaped by experience, as is the case for language.

Do So

The exact mechanism of the evolution of language remains unknown. One of the central problems in this field is the issue of reliability and deceit that can be characterized in terms of honest signaling theory. Communication systems become vulnerable to dishonesty and deceit when there are conflicting interests between the signaler and receiver. The handicap principle explains how evolution can prevent animals from deceiving each other even if they have a strong incentive to do so. It suggests that the signals must be costly in order to provide accurate and reliable communication between animals. Language-like communication systems, being inherently vulnerable to deception, could only evolve and become evolutionarily stable if they had some mechanisms that can make the communication hard to fake and trustworthy. One of the theories that try to solve the problem of reliability and deception is the ritual/speech coevolution hypothesis. According to this theory, hard-to-fake rituals evolved concurrently with language - by reinforcing trust and solidarity among early humans and preventing deceitful and manipulative behavior within the group. One of the drawbacks of this hypothesis is that the relationship between ritual and speech is too indirect. Rituals could not have a real-time effect on every instance of speech and encompass all aspects of everyday language communication. Therefore they are not efficient enough to provide instant verification mechanisms to guarantee honest communication. It is more likely that the animistic nature of language itself, rather than ritual, was the handicap-like cost that helped to ensure the reliability of language during its origin. The belief in the parallel dimension of animistic spirits emerged concurrently with language as a hard-to-fake attestation mechanism that ensured inviolability of one's speech. The notion that animism emerged because of early behaviorally modern humans’ incoherent and flawed observations about the natural world is unlikely, because it implies a very improbable scenario, that there had been a more coherent and rational pre-animistic period which later degraded to animistic one.

Key Issues

Abstract In recent years, multiple researchers working on the evolution of language have put forward the idea that the theoretical framework of usage-based approaches and Construction Grammar is highly suitable for modelling the emergence of human language from pre-linguistic or proto-linguistic communication systems. This also raises the question of whether usage-based and constructionist approaches can be integrated with the analysis of animal communication systems. In this paper, we review possible avenues where usage-based, constructionist approaches can make contact with animal communication research, which in turn also has implications for theories of language evolution. To this end, we first give an overview of key assumptions of usage-based and constructionist approaches before reviewing some key issues in animal communication research through the lens of usage-based, constructionist approaches. Specifically, we will discuss how research on alarm calls, gestural communication and symbol-trained animals can be brought into contact with usage-based, constructionist theorizing. We argue that a constructionist view of animal communication can yield new perspectives on its relation to human language, which in turn has important implications regarding the evolution of language. Importantly, this theoretical approach also generates hypotheses that have the potential of complementing and extending results from the more formalist approaches that often underlie current animal communication research.

The Relationship

Language is one of only a handful of human cultural systems that is both unique to our species, and universal. This chapter will focus on the cultural evolution of language, situating this alongside the phylogenetic and developmental timescales which also feed into the evolution of language. The chapter begins by outlining the relationship between the emergence of human language and the language faculty and the more rapid, ongoing processes of language change, which are often framed as predominantly cultural. In particular, previous work has emphasised how these timescales interact, and how cultural factors in particular shape which aspects of language exhibit broad cross-cultural variation or stability. This is followed by detailed evidence for this relationship from three domains, focusing on the role of cultural evolution in language as observed in natural language (both historical corpora and cross linguistic data), the cultural evolution of language in agent-based models, and finally, experimental studies of the cultural evolution of language. We conclude that the study of the cultural evolution of language forms an important data-rich model for the study of the evolution of cultural systems more generally, while also providing key insights into the specific dynamics of this uniquely human behaviour.

Abstract Several evolutionary accounts of human social cognition posit that language has co-evolved with the sophisticated mindreading abilities of modern humans. It has also been argued that these mindreading abilities are the product of cultural, rather than biological, evolution. Taken together, these claims suggest that the evolution of language has played an important role in the cultural evolution of human social cognition. Here we present a new computational model which formalises the assumptions that underlie this hypothesis, in order to explore how language and mindreading interact through cultural evolution. This model treats communicative behaviour as an interplay between the context in which communication occurs, an agent’s individual perspective on the world, and the agent’s lexicon. However, each agent’s perspective and lexicon are private mental representations, not directly observable to other agents. Learners are therefore confronted with the task of jointly inferring the lexicon and perspective of their cultural parent, based on their utterances in context. Simulation results show that given these assumptions, an informative lexicon evolves not just under a pressure to be successful at communicating, but also under a pressure for accurate perspective-inference. When such a lexicon evolves, agents become better at inferring others’ perspectives; not because their innate ability to learn about perspectives changes, but because sharing a language (of the right type) with others helps them to do so.

AbstractThe article argues that humans are endowed with an inborn language faculty. The ‘Basic Property’ of language is defined as a finitely-specified procedure represented in the brain, which generates a discrete infinity of hierarchically structured expressions. These unordered structures are linked to two interfaces: (i) the sensorimotor interface and (ii) the conceptual-intentional interface. The sensorimotor interface externalizes and linearizes internal structures, usually in the sound modality. Externalization and linearization account for the structural diversity of the world’s languages. Human language did not evolve from simpler communication systems. The available evidence suggests that language is primarily an instrument of thought, not of communication.

Main Component

Comparative research has proven to be a fruitful field of study on the ontogenetic and phylogenetic evolution of language, and on the cognitive capacities unique to humans or shared with other animals. The degree of continuity between components of human language and non-human animal communication systems, as well as the existence of a core factor of language, are polemic subjects at present. In this article, we offer an overview of the research on animal communication, comparing the resulting data with the current knowledge on human language development. We try to summarize what is currently known about “language abilities” in multiple animals, and compare those facts to what is known about human language. The aim of the article is to provide an introduction to this particular topic, presenting the different sides of the arguments when possible. A special reference is made to the question of syntactic recursion as the main component of language, allegedly absent among non-human animals. We conclude that the current state of knowledge supports the existence of a certain degree of continuity between different aspects of animal communication and human language, including the syntactic domain.
