Many animals produce vocal sequences that appear complex. Most researchers assume that these sequences are well characterized as Markov chains (i.e. that the probability of a particular vocal element can be calculated from the history of only a finite number of preceding elements). However, this assumption has never been explicitly tested. Furthermore, it is unclear how language could evolve in a single step from a Markovian origin, as is frequently assumed, as no intermediate forms have been found between animal communication and human language. Here, we assess whether animal taxa produce vocal sequences that are better described by Markov chains, or by non-Markovian dynamics such as the ‘renewal process’ (RP), characterized by a strong tendency to repeat elements. We examined vocal sequences of seven taxa: Bengalese finches Lonchura striata domestica , Carolina chickadees Poecile carolinensis , free-tailed bats Tadarida brasiliensis , rock hyraxes Procavia capensis , pilot whales Globicephala macrorhynchus , killer whales Orcinus orca and orangutans Pongo spp . The vocal systems of most of these species are more consistent with a non-Markovian RP than with the Markovian models traditionally assumed. Our data suggest that non-Markovian vocal sequences may be more common than Markov sequences, which must be taken into account when evaluating alternative hypotheses for the evolution of signalling complexity, and perhaps human language origins.

The object of study in the present article is birds, more precisely the sounds of birds as they are represented in Estonian nature writing. The evolutionary and structural parallels of bird song with human language are reviewed. Human interpretation of bird sounds raises the question, whether it is possible to transmit or “translate” signals between the Umwelts of different species. The intentions of the sender of the signal may remain unknown, but the signification process within human Umwelt can still be traced and analysed. By approaching the excerpts of nature writing using semiotic methodology, I attempt to demonstrate how bird sounds can function as different types of signs, as outlined by Thomas A. Sebeok. It is argued that the zoosemiotic treatment of nature writing opens up a number of interesting perspectives that would otherwise remain beyond the scope of traditional literary analysis.

Colorectal cancer is the second most frequently diagnosed cancer in Poland as well as in the world. In addition, this cancer is the second cause of death among oncological diseases. Genetic and environmental factors with a documented impact on the development and progression of colorectal cancer have been thoroughly investigated. Every case of colorectal cancer begins with the stage of a nonmalignant polyp, whose progression to invasive malignant tumor lasts about 10 years. This period is long enough to implement appropriate preventive action that allow early detection and treatment of pre-cancerous lesions. Colorectal cancer screening is the process of detecting polypoid lesions in asymptomatic patients with no history of cancers. Colonoscopy has the benefit of diagnostic and therapeutic tools, which allows to detect and remove of premalignant polyps in a single step approach. The aim of this work is to present the role of a screening program in the prevention of colorectal cancer.

The article is devoted to identifying the role of the «Dictionary of the Chuvash language» by N.I. Ashmarin in revealing the mental foundations of modern Chuvash and in determining the sociocultural and psychological type of character of the Chuvash. The relevance of the study is due to the fact that during the period of globalization and universalization of cultures, the return to the original values of the nation, the search for individual-folk traits of a person's character in his worldview and lifestyle, which is most clearly recorded in his language, is of great importance. The human language retains a large amount of information that contributes to its spiritual, scientific, technical and industrial development. Therefore, the analysis of vocabulary also contributes to the study of the history of the development of man, people, nation, humanity. The purpose of the research is to study the socio-historical, cultural and ethical information enshrined in the vocabulary of the people and recorded in this dictionary. The principles of methodology, that reflect elements of conceptology, hermeneutics and general philology are used in the study. It is concluded that the Chuvash language (more broadly, the Chuvash culture) is an integral part of the ancient Turkic world, therefore research in this direction expands the framework of understanding the philosophy, history, theology and everyday life of the Chuvash people.

Human language, music and a variety of animal vocalizations constitute ways of sonic communication that exhibit remarkable structural complexity. While the complexities of language and possible parallels in animal communication have been discussed intensively, reflections on the complexity of music and animal song, and their comparisons, are underrepresented. In some ways, music and animal songs are more comparable to each other than to language as propositional semantics cannot be used as indicator of communicative success or wellformedness, and notions of grammaticality are less easily defined. This review brings together accounts of the principles of structure building in music and animal song. It relates them to corresponding models in formal language theory, the extended Chomsky hierarchy (CH), and their probabilistic counterparts. We further discuss common misunderstandings and shortcomings concerning the CH and suggest ways to move beyond. We discuss language, music and animal song in the context of their function and motivation and further integrate problems and issues that are less commonly addressed in the context of language, including continuous event spaces, features of sound and timbre, representation of temporality and interactions of multiple parallel feature streams. We discuss these aspects in the light of recent theoretical, cognitive, neuroscientific and modelling research in the domains of music, language and animal song.

Le commentaire que propose Merleau-Ponty de L’origine de la géométrie de Husserl en 1960 accorde une place privilégiée au langage, à l’écrit : l’étonnement peut être grand de voir Merleau-Ponty, dans la continuité de Husserl, penser la genèse de l’idéalité géométrique à partir d’une méditation sur la littérature. La réflexion de Merleau-Ponty sur la littérature a pris un tour ontologique décisif au début des années cinquante, dans le long commentaire de Proust notamment en 1953-1954. C’est dans cet esprit que le cours de 1960 accorde à la littérature un sens ontologique : l’idéalité géométrique ne peut advenir comme idéalité que par passage à la parole et à l’écrit, mais le sens même de l’idéalité scientifique ne peut se comprendre que si on la replace sur fond d’idéalités plus fondamentales que la littérature précisément dévoile, idéalités qui se nouent à travers le temps, dans le lien entre le passé et le présent, moi et l’autre. La littérature éclaire l’histoire de la géométrie d’une autre manière encore : elle met au jour l’entrelacement homme-langage-monde, condition d’émergence d’un sens vrai, qui advient dans l’histoire de la géométrie, et que la littérature, assumant notre être de parole, porte plus fondamentalement encore.The commentary Merleau-Ponty offers in 1960 on Husserl’s The Origin of Geometry gives a privileged place to language, to writing: it is perhaps a great astonishment to see Merleau-Ponty, in continuity with Husserl, thinking about the genesis of geometrical ideality beginning from a meditation on literature. Merleau-Ponty’s reflection on literature took a decisive ontological turn at the beginning of the 1950s, notably in the long commentary on Proust in 1953-1954. It is in this spirit that the course of 1960 grants to literature an ontological sense: the ideality of geometry can occur as ideality by the passage to speech and to writing, but the meaning of even scientific ideality can be understood only if one places it on the basis of more fundamental idealities that literature precisely reveals, idealities that are linked across time, in the connection between past and present, self and other. Literature clarifies the history of geometry in yet another manner: it brings to light the intertwining of human-language-world, condition of the emergence of a true sense, which occurs in the history of geometry, and which literature, assuming our being in speech bears more fundamentally still.Il commento de L’origine della geometria di Husserl proposto da Merleau-Ponty nel 1960 accorda un posto privilegiato al linguaggio, alla scrittura. Ci si potrebbe stupire del fatto che Merleau-Ponty, nel solco di Husserl, pensi l’idealità geometrica a partire da una riflessione sulla letteratura. Il pensiero di Merleau-Ponty sulla letteratura ha assunto un’inflessione ontologica decisiva all’inizio degli anni Cinquanta, in particolare nel lungo commento a Proust del 1953-1954. È proprio prolungando questa linea che il corso del 1960 attribuisce alla letteratura un senso ontologico: l’idealità geometrica diviene idealità proprio nel passaggio dalla parola allo scritto, ma il senso stesso dell’idealità scientifica può essere compreso solo se ricollochiamo quest’ultima su quello sfondo di idealità più fondamentali che la letteratura ci rivela, idealità che si instaurano attraverso il tempo, nel legame tra il passato e il presente, l’io e l’altro. Infine, è in un altro modo ancora che la letteratura illumina la storia della geometria: essa ci consente di illuminare l’intreccio uomo-linguaggio-mondo, condizione di emergenza di un senso vero, che si attesta nella storia della geometria e che la letteratura, in quanto essa assume il nostro essere già da sempre implicati con la parola, reca con sé in modo ancora più fondamentale.

AbstractThis article examines certain aspects of the history of the doctrines of equivocation and mental reservation in early modern Catholic elaborations. It argues that the first Catholic theologians who engaged systematically with these doctrines, Domingo de Soto and Martin de Azpilcueta (Navarrus), used them as tools to investigate the potentialities and limitations of human language as a means to communicate meaning between a speaker and a listener. This article also shows that between the end of the sixteenth and the beginning of the seventeenth centuries Catholic theologians, both Jesuit and non-Jesuit, changed the debate over these doctrines into a debate over the moral quality of the speaker's intention. By analyzing the developments of the Catholic debate over equivocation and mental reservation, this article seeks to offer a fresh interpretation of the links between theology, morality, and hermeneutics.

Human language is qualitatively different from animal communication systems in at least two separate ways. Human languages contain tens of thousands of arbitrary learned symbols (mainly words). No other animal communication system involves learning the component symbolic elements afresh in each individual's lifetime, and certainly not in such vast numbers. Human language also has complex compositional syntax. The meanings of our sentences are composed from the meanings of the constituent parts (e.g. the words). This is obvious to us, but no other animal communication system (with honeybees as an odd but distracting exception) puts messages together in this way. A recent theoretical claim that the sole distinguishing feature of human language is recursion is discussed, and related to these features of learned symbols and compositional syntax. It is argued that recursive thought could have existed in prelinguistic hominids, and that the key step to language was the innovative disposition to learn massive numbers of arbitrary symbols

The ‘social complexity hypothesis’ for communication posits that groups with complex social systems require more complex communicative systems to regulate interactions and relations among group members. Complex social systems, compared with simple social systems, are those in which individuals frequently interact in many different contexts with many different individuals, and often repeatedly interact with many of the same individuals in networks over time. Complex communicative systems, compared with simple communicative systems, are those that contain a large number of structurally and functionally distinct elements or possess a high amount of bits of information. Here, we describe some of the historical arguments that led to the social complexity hypothesis, and review evidence in support of the hypothesis. We discuss social complexity as a driver of communication and possible causal factor in human language origins. Finally, we discuss some of the key current limitations to the social complexity hypothesis—the lack of tests against alternative hypotheses for communicative complexity and evidence corroborating the hypothesis from modalities other than the vocal signalling channel.

The evolution of language is investigated by various research communities (including biologists and linguists) which engage in comparative works to highlight similar linguistic capacities across species. So far though, no consensus exists on linguistic capacities of nonhuman species. Rather, vivid debates have emerged, mostly fuelled by misuses of linguistic terminology, irrelevance of analysis methods and inappropriate behavioural data collection. The field of ‘animal linguistics’ has recently emerged to overcome these difficulties, notably by increasing exchanges and collaborations across disciplines, in an attempt to reach unique methods and terminology.This primer on ‘animal linguistics’ is a tutorial review on the study of animal communication using both linguistic and biological methods, aimed at both the linguistic and biology communities. Specifically, it aims at accompanying researchers from either of these fields to collect data, run analyses and draw conclusions step by step, and in a way that could satisfy the other research community. To this end, it first exposes the linguistic theoretical concepts of semantics, pragmatics and syntax, and proposes the minimal criteria that are to be fulfilled to claim that a given species displays one – or several – linguistic capacities. Second, it reviews relevant methods successfully applied to the study of animal data. Third, it proposes guidelines to detect and overcome major pitfalls commonly observed in the collection of animal behaviour data. As observed in the past history of science, research traditions can be fragile if not sustained by collaborative communities. We believe this article to represent a milestone towards mutual understanding and fruitful collaborations between linguists and biologists.
