There has been a long-standing controversy in the context of language evolution on whether the original function of human language was internal thought or external communication. However, given the fact that language clearly serves both functions, internalization and externalization must have been co-evolutionarily acted in the emergence of human language. This article proposes a theoretical hypothesis about this co-evolutionary relationship of internalization and externalization, which especially explains the emergence of the human lexicon. To discuss the evolution of (...) language from a comprehensive perspective, this article proposes a promising model that integrates two approaches with different standpoints: generative grammar and cognitive linguistics. This paper also examines the definition and nature of the lexicon and lexical items based on this integrated model. The hypothesis presented here demonstrates that the co-evolutionary work of internalization and externalization has been involved in two processes in the development of the lexicon: the establishment of syntactic objects (lexical items) and the improvement of creativity responsible for the expansion of lexicon size. The main conclusion is that these processes have formed a positive feedback loop and provided our lexicon with complex and unique properties. (shrink)

The sound system of a language must be able to support a perceptual contrast between different words in order to signal communicatively relevant meaning distinctions. In this paper, we use a simple agent-based exemplar model in which the evolution of sound-category systems is understood as a co-evolutionary process, where the range of variation within sound categories is constrained by functional pressure to keep different words perceptually distinct. We show that this model can reproduce several observed effects on the range (...) of sound variation. We argue that phonological systems can be seen as finding a relative optimum of variation: Efficient communication is sustained while at the same time, hidden category variation provides pathways for future evolution.

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 with others helps them to do so.

Language- and music-readiness are demonstrated as related within comparative neuroprimatology by elaborating three hypotheses concerning music-readiness (MR): The (musicological) rhythm-first hypothesis (MR-1), the combinatoriality hypothesis (MR-2), and the socio-affect-cohesion hypothesis (MR-3). MR-1 states that rhythm precedes evolutionarily melody and tonality. MR-2 states that complex imitation and fractionation within the expanding spiral of the mirror system/complex imitation hypothesis (MS/CIH) lead to the combinatorial capacities of rhythm necessary for building up a musical lexicon and complex structures; and rhythm, in connection with (...) repetition and variation, scaffolds both musical form and content. MR-3 states that music’s main evolutionary function is to self-induce affective states in individuals to cope with distress; rhythm, in particular isochrony, provides a temporal framework to support movement synchronization, inducing shared affective states in group members, which in turn enhances group cohesion. This document reviews current behavioural and neurocognitive research relevant to the comparative neuroprimatology of music-readiness. It further proposes to extend MS/CIH through the evolution of the relationship of the language- and music-ready brain, by comparing “affective rhythm” and prosody – i.e. by comparatively approaching the language- and music-emotion link in neuroprimatology.

We examined the role of fitness, commonly assumed without proof to be conferred by the mastery of language, in shaping the dynamics of language evolution. To that end, we introduced island migration (a concept borrowed from population genetics) into the shared lexicon model of communication (Nowak et al., 1999). The effect of fitness linear in language coherence was compared to a control condition of neutral drift. We found that in the neutral condition (no coherence-dependent fitness) even a small (...) migration rate – less than 1% – suffices for one language to become dominant, albeit after a long time. In comparison, when fitness-based selection is introduced, the subpopulations stabilize quite rapidly to form several distinct languages. Our findings support the notion that language confers increased fitness. The possibility that a shared language evolved as a result of neutral drift appears less likely, unless migration rates over evolutionary times were extremely small. (shrink)

The main designs of modern theories of syntax assume a process of syntagmatic organization. However, research on first language acquisition leaves no doubt that the structured combination of single lexical items cannot begin until a critical mass of lexical items has been acquired such that the lexicon is structured hierarchically on the basis of hierarchical feature bundling. Independent of a decision between the main views about the design of a proto language (the grammarless “Holophrastic view”,Arbib & Bickerton 2010: 1,Bickerton (...) 2014) or the ‘Compositional View’ as taken byRizzi (2010),Carstairs-McCarthy (2010), and others. What seems to be the minimal offset for language is the existence of grammatical categories like verb and noun, on the one hand, and, on the other hand, functional categories as needed for the expression of all kinds of agreement between the distinct categories to form recursively structured complexes. I follow the different stages of complexification asking whether there is paradigmatic next to syntagmatic organization and what its added value is for the evolution of grammar. The conclusion will be that paradigmatics is an indismissible part of the organization of early language in that it structures the lexicon so as to make primary and secondary syntactic merge possible and, consequently, is also a prerequisite for movement. The guiding idea of this position is Roman Jakobson’s insistence on the twofold organization of language and grammar. The two organizational designs, syntagmatics and paradigmatics, are manifest within each module: in the phonetic, the morphological, the syntactic, the semantic, and the pragmatic form (consider Jakobson’s1971a,breiterated argument).

"Few thinkers have stood as squarely at both the center and the periphery of an intellectual movement as has Shao Yung (1011-1077). Ethical model and eccentric, socialite and eremite, Shao Yung is perhaps not only the greatest enigma of early Neo-Confucianism, but also one of its undisputed giants. In this impressive life-and-thought study, Don J. Wyatt painstakingly sifts through all available evidence relating to Shao Yung and his scholarship to provide a portrait that fully exposes the moral center of the (...) man and his work. Drawing on the abundant store of letters and accounts by Shao's contemporaries and his own much-neglected poetry, Wyatt has assembled a study that intimately relates Shao's life to his thought. He challenges the assumptions of previous Western scholarship by persuasively arguing against the acceptance of works traditionally ascribed to Shao - specifically, the Kuan-wu wai-p'ien (Outer Chapters on Observing Things), the Yu-ch'iao wen-ta (Fisherman and Woodcutter Dialogue), and the cryptic quasi-autobiographical essay Wu-ming kung chuan (Biography of the Nameless Lord)." "Shao is presented as an independent thinker whose philosophical lexicon functioned according to a profound interdependence that was unique among the systems of his peers. His metaphysical concepts, which appear impervious to and beyond the scope of human influence - namely, his ching-shih (world ordering), kuan-wu (observing things), and I-Ching - derived hsien-t'ien (before Heaven) methodologies - are essentially the products of a morally reflective life. Wyatt's discoveries, therefore, refute the common assertion of Shao Yung's moral indifference. Moreover, by meticulously integrating the progress of this Neo-Confucian's thought into the course of his life, the author has produced one of the most textured and accessible works on a philosopher of the Sung era."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Words are processed more easily when they have canonical phonotactic shapes, i.e., shapes that are frequent both in the lexicon and in usage. We explore whether this cognitively grounded constraint or preference implies testable predictions about the implementation of sound change. Specifically, we hypothesise that words with canonical shapes favour, or ‘select for’, sound changes that produce words with the same shapes. To test this, we investigate a Middle English sound change known as Open Syllable Lengthening. OSL lengthened vowels (...) in disyllables such as ME /ma.kə/ make, but more or less only when they became monosyllabic and when their vowels were non-high. We predict that word shapes produced by this implementation pattern should correspond to the shapes that were most common among morphologically simple monosyllables and disyllables at the time when OSL occurred. We test this prediction against Early Middle English corpus data. Our results largely confirm our prediction: monosyllables produced by OSL indeed conformed to the shapes that were most frequent among already existing monosyllables. At the same time, the failure of OSL to affect disyllables prevented them from assuming shapes that were far more typical of morphologically complex word forms than of simple ones. This suggests that the actuation and implementation of sound changes may be even more sensitive to lexical probabilities than hitherto suspected. Also, it demonstrates how diachronic data can be used to test hypotheses about constraints on word recognition and processing. (shrink)

This article describes the methods involved in building a diachronic multilingual corpus devoted to Fine Arts, beginning with G. Vasari's Lives of the most excellent Italian architects, sculptors and painters (1568) as the fundamental source text in the field of Art History. Attention is given to automatic pre-alignment, the special proofreading protocol and segmentation rules developed to allow multilingual and/or diachronic alignment of multiple texts, and the difficulties inherent in annotating a multilingual database. A case study is offered, comparing the (...) term “tondo” and its variants (e.g. “mezzo tondo”, “di tondo rilievo”) in Italian with their translations in English (De Vere 1912-15) and French (Leclanché 1839, Chastel 1981, Luciani 2002, Powell 2007). These later translations contain a greater variety of both lexicalized counterparts such as “medallion” or “lunette” as well as paraphrases, used to disambiguate and distinguish the various meanings of “tondo”, thus demonstrating how artistic vocabulary, which was still developing in 16th c. Italian, through its transmission to other languages, became more diversified and stable over time. (shrink)

The purpose of this article is to analyze the figure of the monarch presented in Dante's “De Monarchia”. The study of Dante's political project will provide us with an opportunity to see the shifts in intellectual environment of the late Middle Ages through the evolution or perhaps return from the theocratic model to the earlier pre-Christial concept of the ruler. The study of Dante's political lexicon will demonstrate the revival of the original meanings starting to challenge and shift (...) the consensus of the political philisophy at the time. (shrink)

An analysis of a valenced corpus of English words revealed that words that rhyme with slurs are rated more poorly than their synonyms. What at first might seem like a bizarre coincidence turns out to be a robust feature of slurs, one arising from their phonetic structure. We report novel data on phonaesthetic preferences, showing that a particular class of phonemes are both particularly disliked, and overrepresented in slurs. We argue that phonaesthetic associations have been an overlooked source of some (...) of the more peculiar, arational aspects of slurs. We conclude by drawing broader morals about the evolution of the lexicon. (shrink)

The two dominant theories of consciousness argue it appeared in living beings either suddenly, or gradually. Both theories face problems. The solution is the realization that a foundational consciousness was always here, yet varying conscious states were not, and appeared gradually. Michael Tye explores this idea and the key questions it raises.

The structure of the brain and the nature of evolution suggest that, despite its uniqueness, language likely depends on brain systems that also subserve other functions. The declarative / procedural model claims that the mental lexicon of memorized word- specific knowledge depends on the largely temporal-lobe substrates of declarative memory, which underlies the storage and use of knowledge of facts and events. The mental grammar, which subserves the rule-governed combination of lexical items into complex representations, depends on a (...) distinct neural system. This system, which is composed of a network of specific frontal, basal - ganglia, parietal and cerebellar structures, underlies procedural memory, which supports the learning and execution of motor and cognitive skills, especially those involving sequences. The functions of the two brain systems, together with their anatomical, physiological and biochemical substrates, lead to specific claims and predictions regarding their roles in language. These predictions are compared with those of other neurocognitive models of language. Empirical evidence is presented from neuroimaging studies of normal language processing, and from developmental and adult- onset disorders. It is argued that this evidence supports the DP model. It is additionally proposed that “ language ” disorders, such as specific language impairment and non-fluent and fluent aphasia, may be profitably viewed as impairments primarily affecting one or the other brain system. Overall, the data suggest a new neurocognitive framework for the study of lexicon and grammar. (shrink)

Because human cognition is creative and socially situated, knowledge accumulates, diffuses, and gets applied in new contexts, generating cultural analogs of phenomena observed in population genetics such as adaptation and drift. It is therefore commonly thought that elements of culture evolve through natural selection. However, natural selection was proposed to explain how change accumulates despite lack of inheritance of acquired traits, as occurs with template-mediated replication. It cannot accommodate a process with significant retention of acquired or horizontally (e.g. socially) transmitted (...) traits. Moreover, elements of culture cannot be treated as discrete lineages because they constantly interact and influence one another. It is proposed that what evolves through culture is the mind; ideas and artifacts are merely reflections of its current evolved state. Interacting minds transform (in part) through through a non-Darwinian autopoietic process similar to that by which early life evolved, involving not survival of the fittest but actualization of their potential.

This book offers a compelling account of the evolution of sensibility, weaving together Darwinian and biosemiotic theory. It works along non-anthropomorphic aesthetics of the appreciation and creation of beauty in nature as an end in itself which has practical benefit.

In seeking to explain the evolution of social cooperation, many scholars are using increasingly complex game-theoretic models. These complexities often model readily observable features of human and animal populations. In the case of previous games analyzed in the literature, these modifications have had radical effects on the stability and efficiency properties of the models. We will analyze the effect of adding spatial structure to two communication games: the Lewis Sender-Receiver game and a modified Stag Hunt game. For the Stag (...) Hunt, we find that the results depart strikingly from previous models. In all cases, the departures increase the explanatory value of the models for social phenomena. (shrink)

Although a substantial literature in anthropology and comparative religion explores divination across diverse societies and back into history, little research has integrated the older ethnographic and historical work with recent insights on human learning, cultural transmission, and cognitive science. Here we present evidence showing that divination practices are often best viewed as an epistemic technology, and we formally model the scenarios under which individuals may overestimate the efficacy of divination that contribute to its cultural omnipresence and historical persistence. We found (...) that strong prior belief, underreporting of negative evidence, and misinferring belief from behavior can all contribute to biased and inaccurate beliefs about the effectiveness of epistemic technologies. We finally suggest how scientific epistemology, as it emerged in Western societies over the past few centuries, has influenced the importance and cultural centrality of divination practices.

It also presents data indicating that there is a viable alternative to the present, potentially lethal, emphasis on technologies of domination and destruction. (shrink)

Follows up on Rumelhart's (1979) proposal that words don’t have meaning, but are cues to meaning (functioning as operators on our mental states, rather than operands or objects of analysis).

We compare and contrast the 60 commentaries by 109 authors on the pair of target articles by Mehr et al. and ourselves. The commentators largely reject Mehr et al.'s fundamental definition of music and their attempts to refute (1) our social bonding hypothesis, (2) byproduct hypotheses, and (3) sexual selection hypotheses for the evolution of musicality. Instead, the commentators generally support our more inclusive proposal that social bonding and credible signaling mechanisms complement one another in explaining cooperation within and (...) competition between groups in a coevolutionary framework (albeit with some confusion regarding terminologies such as “byproduct” and “exaptation”). We discuss the proposed criticisms and extensions, with a focus on moving beyond adaptation/byproduct dichotomies and toward testing of cross-species, cross-cultural, and other empirical predictions.

Recent years have seen the growing promise of cultural evolutionary theory as a new approach to bringing human behaviour fully within the broader evolutionary synthesis. This review of two recent seminal works on this topic argues that cultural evolution now holds the potential to bring together fields as disparate as neuroscience and social anthropology within a unified explanatory and ontological framework.

The Marxian visions of the post-capitalist future evolved with significant changes over three decades. From the outset Marx and Engels divided the future into stages, economically and philosophically, a final communist or socialist stage, and a transitional stage or stages preceding it. The final stage remained largely constant throughout, the actualization of the ideal of Feuerbach's anthropological philosophy, supplemented by Fourier's ideas for the abolition of the division of labor and its transformation into pleasurable activity. The original institutional conception was (...) pastoral, adopted from Owen's communal plans and materialistic determinism, with socialized means of production and comprehensive communal control of social and economic life. They substituted for Owen's equal labor-time exchange principle Cabet's principle of from each according to his abilities, to each according to his needs, and estimated the duration of the transition at one to two years. Interpreting history according to Hegel's dialectic they conceived this future as the inevitable result of a revolution dialectically effecting the complete rehumanization of a totally dehumanized proletariat, whose consciousness accomplishes the revolution and recovers its theretofore alienated nature. ;With the subsequent formulation of the theory of historical materialism and its conception of all history as class conflict their published descriptions of the final stage became brief and vague and it was relegated to an increasingly remote future, based on varying material and social requirements which would transform human nature sometime during these increasingly lengthy transitional stages. To preserve the material accomplishments of capitalism they substituted state centralization for Owen's communalism, but began to misrepresent this for tactical political reasons, defining the state and classes solely in terms of property, state expropriation thereby abolishing the state. Retaining Cabet's principle for the final stage, they formulated a succession of contradictory principles of production and distribution within a varying number of transitional stages. These principles ranged from the equal exchange of labor time, through unequal distribution for equal labor time based on results, and finally to equal distribution for unequal labor time and results. The most egalitarian plans were the most widely publicized, the least egalitarian restricted in circulation. (shrink)

In an attempt to provide a unified model of language-related mental processes, Jackendoff puts forward significant modifications to the generative architecture of the language faculty. While sympathetic to the overall objective of the book, my review points out that one aspect of the proposal – the status of the lexicon – lacks sufficient empirical support.

Polyphenic differences between individuals arise not through differences at the genome level but as a result of specific cues received during development. Polyphenisms often involve entire suites of characters, as shown dramatically by the polyphenic castes found in many social insect colonies. An understanding of the genetic architecture behind polyphenisms provides a novel means of studying the interplay between genomes, gene expression and phenotypes. Here we discuss polyphenisms and molecular genetic tools now available to unravel their developmental bases in insects. (...)

Originating in the work of Ernst Haeckel and Wilhelm Preyer, and advanced by a Prussian embryologist, Wilhelm Roux, the idea of struggle for existence between body parts helped to establish a framework, in which population cell dynamics rather than a predefined harmony guides adaptive changes in an organism. Intended to provide a causal-mechanical view of functional adjustments in body parts, this framework was also embraced later by early pioneers of immunology to address the question of vaccine effectiveness and pathogen resistance. (...) As an extension of these early efforts, Elie Metchnikoff established an evolutionary vision of immunity, development, pathology, and senescence, in which phagocyte-driven selection and struggle promote adaptive changes in an organism. Despite its promising start, the idea of somatic evolution lost its appeal at the turn of the twentieth century giving way to a vision, in which an organism operates as a genetically uniform, harmonious entity.

Developing ethical standards for clinical use of large-scale genome and exome sequencing has proven challenging, in part due to the inevitability of incidental or secondary findings. Policy of the American College of Medical Genetics and Genomics has evolved but remains problematic. In 2013, ACMG issued policy recommending mandatory analysis of 56 extra genes whenever sequencing was ordered for any indication, in order to ascertain positive findings in pathogenic and actionable genes. Widespread objection yielded a 2014 amendment allowing patients to opt-out (...) from analysis of the extra genes. In 2015, ACMG published the amended policy, providing that patients could opt out of the full set of extra genes, but not a subset. In 2016, ACMG enlarged the set and indicated planned expansion of the roster of extra genes to include pharmacogenetic findings. ACMG policy does not protect the respect for patient choice that prevails in other domains of clinical medicine, where informed consent allows patients to opt in to desired testing. By creating an expanding domain of genomic testing that will be routinely conducted unless patients reject the entire set of extra tests, ACMG creates an exceptional domain clinical practice that is not supported by ethics or science.

Theoretical minimal RNA rings attempt to mimick life’s primitive RNAs. At most 25 22-nucleotide-long RNA rings code once for each biotic amino acid, a start and a stop codon and form a stem-loop hairpin, resembling consensus tRNAs. We calculated, for each RNA ring’s 22 potential splicing positions, similarities of predicted secondary structures with tRNA vs. rRNA secondary structures. Assuming rRNAs partly derived from tRNA accretions, we predict positive associations between relative secondary structure similarities with rRNAs over tRNAs and genetic code (...) integration orders of RNA ring anticodon cognate amino acids. Analyses consider for each secondary structure all nucleotide triplets as potential anticodon. Anticodons for ancient, chemically inert cognate amino acids are most frequent in the 25 RNA rings. For RNA rings with primordial cognate amino acids according to tRNA-homology-derived anticodons, tRNA-homology and coding sequences coincide, these are separate for predicted cognate amino acids that presumably integrated late the genetic code. RNA ring secondary structure similarity with rRNA over tRNA secondary structures associates best with genetic code integration orders of anticodon cognate amino acids when assuming split anticodons (one and two nucleotides at the spliced RNA ring 5′ and 3′ extremities, respectively), and at predicted anticodon location in the spliced RNA ring’s midst. Results confirm RNA ring homologies with tRNAs and CDs, ancestral status of tRNA half genes split at anticodons, the tRNA-rRNA axis of RNA evolution, and that single theoretical minimal RNA rings potentially produce near-complete proto-tRNA sets. Hence genetic code pre-existence determines 25 short circular gene- and tRNA-like RNAs. Accounting for each potential splicing position, each RNA ring potentially translates most amino acids, realistically mimicks evolution of the tRNA-rRNA translation machinery. These RNA rings ‘of creation’ remind the uroboros’ (snake biting its tail) symbolism for creative regeneration. (shrink)

The kin selection theory has recently been criticised on the basis of claiming that genetic relatedness does not play a causal role in the social evolution among individuals of insect societies. We outline here a line of criticism of this view by demonstrating two things. First, there are strong conceptual, theoretical and empirical reasons to think that close genetic relatedness has been necessary for the rise of the helper castes of social insects. And second, once we understand how causal (...) explanation itself results from an interplay of two logically distinct elements, necessity and sufficiency, we can also understand the scenarios in which relatedness does not seem to play a causal role for evolution of helper castes. The result of this analysis is that we should be more careful about the way we frame the empirical data on the evolution of social behaviour. (shrink)

One curious phenomenon of several social groups is that they are ‘redundant’ in the sense that they contain more cooperators than strictly needed to complete certain group tasks, such as foraging. Redundancy is puzzling because redundant groups are particularly susceptible to invasion by defectors. Yet, redundancy can be found in groups formed by a wide range of organisms, including insects and microbes. Birch has recently argued that coercive behaviours might account for redundancy using insect colonies as a case study. However, (...) microbial examples suggest redundancy can evolve without coercive behaviours. This paper formulates an explanation for redundancy that does not require targeted punishment of defectors; instead, it proposes that redundancy might be due to ignorance. Specifically, it is suggested that redundancy evolves as a by-product of selection when group members have to opt whether to cooperate or not while being blind to the strategies of others. Accordingly, possessing information about the strategies of the group members might undermine rather than facilitate cooperation within groups. 1The Evolution of Redundancy 2Explaining Redundancy via Coercion 3Explaining Redundancy via Ignorance 3.1Cooperation behind the Darwinian veil of ignorance 3.2Modelling group tasks with a public goods game 3.3Group tasks under harsh environments 4Conclusion.

Although it originated in theological debates, the general will ultimately became one of the most celebrated and denigrated concepts emerging from early modern political thought.

With the following considerations, the author intends to enrich the discussion about chance and the formation of new organisms in biological evolution. As a physicist, he knows that he has already crossed a boundary of disciplines by discussing the occurrence of chance. The natural scientist or biologist leaves the field of natural science to enter the world of ideas, humanities, and metaphysics. A second argument considers the relation between the whole and its parts. Decomposing biological systems to the smallest (...) building blocks (molecules and atoms) does not mean the whole can be constructed from these particles without additional causal agents.

The evolution of boundedly rational rules for playing normal form games is studied within stationary environments of stochastically changing games. Rules are viewed as algorithms prescribing strategies for the different normal form games that arise. It is shown that many of the “folk results” of evolutionary game theory, typically obtained with a fixed game and fixed strategies, carry over to the present environments. The results are also related to some recent experiments on rules and games.
