VI. Life’s Cerebral Cognizance Becomes More Complex, Smarter, Informed, Proactive, Self-Aware2. Organisms Evolve Rhythmic Protolanguage Communication Honing, Henkjan, et al. Without It No Music: Cognition, Biology and Evolution of Musicality. Philosophical Transactions of the Royal Society B. Vol.370/Iss.1664, 2015. HH, University of Amsterdam, Carel ten Cate, Leiden University, Isabelle Peretz, Montreal University, and Sandra Trehub, University of Toronto introduce an issue to broadly consider innate animal sensitivities to beat, pitch, and rhythm. The project is said to be inspired by YouTube videos of birds dancing to rock tunes, which revealed unexpected eabilities. Some entries are Four Principles of Bio-Musicality by Tecumseh Fitch, a guiding scholar for the endeavor, Evolutionary Roots of Creativity, Principles of Structure Building in Music Language and Animal Song, Finding the Beat across Humans and Non-human Primates, and Cross-cultural Perspectives on Music and Musicality. Follow-up editions are a 2018 volume The Origins of Musicality edited by H. Honing, reviewed herein, and Honing’s own The Evolving Animal Orchestra: In Search of What Makes Us Musical (MIT Press, 2018). Musicality can be defined as a natural, spontaneously developing trait based on and constrained by biology and cognition. What biological and cognitive mechanisms are then essential for perceiving, appreciating and making music? We argue for the importance of identifying these mechanisms and delineating their functions and developmental course, as well as suggesting effective means of studying them in human and non-human animals. It is virtually impossible to underpin the evolutionary role of musicality as a whole, but a multicomponent perspective on musicality that emphasizes its constituent capacities, development and neural cognitive specificity is an excellent starting point for a research programme aimed at illuminating the origins and evolution of musical behaviour as an autonomous trait. (Abstract excerpt) Huang, Mingpan, et al. Male Gibbon Loud Morning Calls Conform to Zipf’s Law of Brevity and Menserath’s Law: Insights into the Origin of Human Language. Animal Behavior. January, 2020. This entry by Sun Yat-Sen University linguists is notable because it reports how these lawful features similarly serve to guide these vocal displays amongst primates. Such a result suggests that they commonly apply across all manner of creaturely communications. See also The Speech-like Properties of Nonhuman Primate Vocalizations by Thore Bergman, et al in this journal (151/229, 2019). The study of vocal communication in nonhuman primates offers critical insight into the origins of human language. Although human language represents a highly derived and complex form of communication, researchers have found that the organization of language follows a series of common statistical patterns, known as ‘linguistic laws’. Zipf's law of brevity and Menzerath's law are pervasive (see below). Here, we provide evidence that the long-distance morning calls of male gibbons follow both laws. Zipf's law of brevity and Menzerath's law. Our findings thus support the generality of these two linguistic laws.. (Abstract) Hurford, James. Linguistics from an Evolutionary Point of View. Kempson, Ruth, et al, eds. Philosophy of Linguistics. Amsterdam: Elsevier, 2012. Volume 14 in a Handbook of the Philosophy of Science series. The emeritus University of Edinburgh linguist and co-founder with Simon Kirby of its Language, Evolution and Computation unit pens an encyclopedia entry which per the quotes advances these findings. A valid recapitulation can be cited between each child and how primates came to speak. In retrospect languages are composed of core segments or modules which array into lexicons and dialogue. In this regard, it is worth citing The Music of Life by geneticist Denis Noble (search), where it is noted that genomes, lyrical scores, and Chinese ideographs are similarly composed of a few prime cases, e.g. basic gene regulatory networks, from which diversities flow. And thirdly, this grand evolutionary production seems to organize, write, score, read, and play itself. The most widely discussed adaptation for speech is the lowering of the larynx. In all other mammals the normal position of the larynx is close up behind where the nasal passage joins the oral passage, just behind the velum. This is also the position of the larynx in newborn human infants, which allows them to breathe and suckle at the same time. During the first half year of life the human larynx lowers to near its later adult position. In this way ontogeny recapitulates phylogeny, as the adult human larynx has lowered in our evolution from apes. (490) Kelley, Kathryn, et al. Seals and signs: tracing the origins of writing in ancient South-west Asia.. Antiquity. November, 2024. In this news noted paper, University of Bologna philologists discern even earlier inklings of relatively textual-like inscriptions used as social records. Administrative innovations in South-west Asia during the fourth millennium BC, including the cylinder seals that were rolled on the earliest clay tablets, laid the foundations for proto-cuneiform script, one of the first writing systems. Seals were rich in iconography, but little research has focused on the potential influence of specific motifs on the sign-based proto-cuneiform script. Here, the authors identify symbolic precursors to fundamental proto-cuneiform signs among late pre-literate seal motifs that describe the transportation of vessels and textiles, highlighting the synergy of early systems of clay-based communication. Kenneally, Christine. Talking through Time: The Role of Knowledge. Scientific American. September, 2018. In an issue on The Science of Being Human, a science journalist and author of The First Word: The Search for the Origins of Language (2007) makes a case for an ancient, evolutionary heritage and course for linguistic and communicative abilities, broadly conceived, as now manifest in our loquacious sapience. Findings from genetics, cognitive science and brain sciences are now converging in a different place. It looks like language is not a brilliant adaptation. Nor is it encoded in the human genome or the inevitable output of our superior human brains. Instead language grows out of a platform of abilities, some of which are very ancient and shared with other animals and only some of which are more modern. (57) Khatami, Fatemeh, et al. Origins of Scale Invariance in Vocalization Sequences and Speech. PLoS Computational Biology. April, 2018. University of Connecticut and University of Marburg, Germany behavioral and biomedical psychologists describe how even our conversations array into self-similar scales which afford their communicative expression. This late year, if to peruse, from interstellar media (Andre Maeder) to social media a common finding appears in our midst that nature (as traditional wisdom long averred) draws upon and repeats one same iconic, archetypal pattern and process in every exemplary instance. The efficient coding hypothesis posits that the brain encodes sensory signals efficiently in order to reduce metabolic cost and preserve behaviorally relevant environment information. A widely observed statistical regularity in nearly all natural sounds is the presence of scale invariance where the power of amplitude fluctuations is inversely related to the sound amplitude modulation frequency. In this study, we explore the physical sound cues responsible for the scale invariant phenomenon previously observed. We demonstrate that for animal vocalizations, including human speech, the scale invariant behavior is fully accounted by the presence of temporal acoustic edges that are largely created by opening and closing of the oral cavity and which mark the beginning and end of isolated vocalizations. The findings thus identify a single physical cue responsible for the universal scale invariant phenomenon that the brain can exploit to optimize coding and perception of vocalized sounds. (Author Summary) Kirby, Simon. Transitions: The Evolution of Linguistic Replicators. Binder, Phillippe and Kenny Smith, eds. The Language Phenomenon: Human Communication from Milliseconds to Millennia. Berlin: Springer, 2013. In this unique volume, the University of Edinburgh chair of language evolution turns to the major transitions scale to situate human linguistic competence within its prior sequential emergence. Eight stages from replicating biomolecules to human societies are each arise due to a novel informative venue as “new ways of communicative transmission.” This persistent temporal context can then expand appreciations of our sapient literacy. In linguistic terms, a better sense of compositionality, holophrastic utterances, and iterated learning is thus gained. For an update survey, see The Emergence of Verse Templates Through Iterated Learning by SK, et al in the Journal of Language Evolution (4/1, 2019). Maynard Smith & Szathmáry’s (1995) work provides a rich framework for thinking about replication. They themselves identified the importance of language in this light, but language is a new system of replication in more than one sense: it is both an enabler of cultural replicators with unlimited heredity, and also a new kind of evolutionary system itself. Iterated learning is the process of linguistic transmission, and it drives both language change and the transitions to qualitatively new kinds of linguistic system. By seeing language as an evolutionary system, the biggest payoff we get may be the ability to take biologists’ insights into the evolution of life and apply them to the evolution of language. (135) Kirby, Simon and Monica Tamariz. Cumulative cultural evolution, population structure and the origin of combinatoriality in human language. Philosophical Transactions of the Royal Society B. December, 2021. In this special Emergence of Collective Knowledge and Cumuulative Culture issue, University of Edinburgh and Heriot-Watt University, Edinburgh linguists post their latest views on how effective communication arose by way of an increasing ability of speakers to join utterances and their content in more complex, meaningful ways. Language is the primary repository and mediator of human collective knowledge. A central question for evolutionary linguistics is the origin of the combinatorial design structure of language. We consider that combinatoriality is the inevitable result of learning biases in cultural transmission, and that population structure explains differences across languages. We employ Bayesian learning agents with a prior preference for compressible languages which communicate in pairs to reduce ambiguity. Results suggest that (1) combinatoriality emerges during iterated cultural transmission under concurrent pressures for simplicity and expressivity and (2) population dynamics affect the rate of evolution, which is faster when agents learn from other learners. (Abstract excerpt) Langus, Alan, et al. Rhythm in Language Acquisition. Neuroscience & Biobehavioral Reviews. 81/B, 2017. Akin to a prosody flow between objects and words being newly integrated into bicameral brain function, here SISSA International School for Advanced Studies, Trieste linguists AL, Jacques Mehler, and Marina Nespor (see each website) show how “universal rhythmic principles” serve to initially guide infants and young language learners across a wide array of ethnic dialects. In so doing, it is alluded that an independent source seems in effect during this “ontogenetic emergence.” Spoken language is governed by rhythm. Linguistic rhythm is hierarchical and the rhythmic hierarchy partially mimics the prosodic as well as the morpho-syntactic hierarchy of spoken language. We identify three universal levels of linguistic rhythm – the segmental level, the level of the metrical feet and the phonological phrase level – and discuss why primary lexical stress is not rhythmic. We survey experimental evidence on rhythm perception in young infants and native speakers of various languages to determine the properties of linguistic rhythm that are present at birth, those that mature during the first year of life and those that are shaped by the linguistic environment of language learners. We conclude with a discussion of the major gaps in current knowledge on linguistic rhythm and highlight areas of interest for future research that are most likely to yield significant insights into the nature, the perception, and the usefulness of linguistic rhythm. (Abstract) Lyon, Caroline, et al, eds. Emergence of Communication and Language. London: Springer, 2007. Co-editors are Chrystopher Nehaniv and Angelo Cangelosi. A large state of the art volume as authorities such as Alison Wray, Tecumseh Fitch, Luc Steels, Eors Szathmary, and many others seek to articulate how cerebral life learned to speak, convey, express, and remember. Ma, Weiyi, et al. Spontaneous Emergence of Language-like and Music-like Vocalizations from an Artificial Protolanguage. Semiotica. Online April, 2019. Behavioral linguists WM, University of Arkansas, Anna Fiveash, University of Lyon, France, and William Forde Thompson, Macquarie University, Sydney experimentally show how cognitive streams innately tend to divide into dual language-like and prosodic musical modes. By a different approach and measure, once again neural nature seems to ever seek these distinctive, reciprocal script and/or score phases, which altogether compose life’s dramatic dance. How did human vocalizations come to acquire meaning in the evolution of our species? Charles Darwin proposed that language and music originated from a common emotional signal system based on the imitation and modification of sounds in nature. This protolanguage is thought to have diverged into two separate systems, with speech prioritizing referential functionality and music prioritizing emotional functionality. However, there has never been an attempt to empirically evaluate the hypothesis that a single communication system can split into two functionally distinct systems that are characterized by music- and language like properties. Here, we demonstrate that when referential and emotional functions are introduced into an artificial communication system, that system will diverge into vocalization forms with speech- and music-like properties, respectively. (Abstract) Massip-Bonet, Angels, et al, eds. Complexity Applications in Language and Communication Sciences. International: Springer,, 2019. Systems linguists A M-B and Albert Bastardas-Boada, University of Barcelona, and Gemma Bel-Enguix, National Autonomous University of Mexico (search each) gather diverse essays about how to perceive human conversant and literary discourse as a complex adaptive, self-organizing network similar to everywhere else. Their Introduction reviews this scientific and conceptual advance through the 2010s as it grows in breath and veracity. Again we may note that by turns, an inherent textual quality across natural and social realms becomes evident. Sample chapters could be The Paradigm of Complexity in Sociology, How and Why to Model the Complexity of Thought Systems, and Amazing Grace: An Analysis of Barack Obama’s Raciolinguistic Performances. This book offers insights on the study of natural language as a complex adaptive system. It discusses a new way to tackle the problem of language modeling, and provides clues on how the close relation between natural language and some biological structures can be very fruitful for science. The book examines the theoretical framework and then applies its main principles to various areas of linguistics. It discusses applications in language contact, language change, diachronic linguistics, and the potential enhancement of classical approaches to historical linguistics by means of new methodologies used in physics, biology, and agent systems theory. It shows how studying language evolution and change using computational simulations enables to integrate social structures in the evolution of language, and how this can give rise to a new way to approach sociolinguistics.
