Our understanding of language, its origins and subsequent evolution, is shaped not only by data and theories from the language sciences, but also fundamentally by the biological sciences. Recent developments in genetics and evolutionary theory offer both very strong constraints on what scenarios of language evolution are possible and probable, but also offer exciting opportunities for understanding otherwise puzzling phenomena. Due to the intrinsic breathtaking rate of advancement in these fields, and the complexity, subtlety, and sometimes apparent (...) non-intuitiveness of the phenomena discovered, some of these recent developments have either being completely missed by language scientists or misperceived and misrepresented. In this short paper, we offer an update on some of these findings and theoretical developments through a selection of illustrative examples and discussions that cast new light on current debates in the language sciences. The main message of our paper is that life is much more complex and nuanced than anybody could have predicted even a few decades ago, and that we need to be flexible in our theorizing instead of embracing a priori dogmas and trying to patch paradigms that are no longer satisfactory.

Within the context of the study of the genetics of language, Chomskian laws of grammar, such as theStructure-dependence Condition and theA over A Condition, may be usefully regarded to have a status similar to that of Mendelian Laws in classical genetics. In both the case of Chomsky's Laws and Mendel's Laws, formal genetic principles are postulated which abstract away from the physical mechanisms involved and in both cases certain apparent counterexamples mirror a more complex underlying genetic organisation.

Madole & Harden describe how genetics can be used in a causal framework. We agree with many of their opinions but argue that comparing within-family designs to experiments is unnecessary and that the proposed influence of genetics on behavior can be better described as inus conditions.

This chapter focuses on one of the common fallacies in Western philosophy called 'genetic fallacy' (GnF). One commits the GnF when advocating for a conclusion based solely on origin. This is a fallacy of relevance—irrelevance, really—because the origin of a claim may be irrelevant to its truth‐value. That is to say, providing an account of the genesis of a claim, its history or origin, may be informative and helpful; however, it need not determine the truth‐value of the claim. Therefore, (...) when one draws a conclusion regarding the truth‐value of a claim based solely on the origin of the claim, then one may have committed the GnF. In the ethical language of “means and ends” reasoning, GnF helps to highlight the problematic nature of the utilitarian‐style disconnect between the justice of actions and the goodness of their consequences.

An analogy is drawn between the processes of human language evolution and the ongoing discoveries concerning how the human genome is constructed. Mutational evolution may be thought of in linguistic terms as an alternation in the genetic code following morphemic substitutions, deletions or additions. This may be termed an endosemiotic analysis where semiotic processes may be found at the biochemical level of the genome. Hence, owing to these genetic changes, phenotypic alterations in the morphology of the organism (...) create those evolutionary changes seen in the development of the phyla in the paleontological record. We are now witnessing the inclusion of the genome of all species both plant and animal within our material culture as we begin to modify these genotypes with recombinant DNA/rna technology. The coevolution of language and the genetic code may then occur as we begin to more thoroughly understand these interrelated evolutionary processes. (shrink)

We suggest there is somewhat more potential than Christiansen & Chater (C&C) allow for genetic adaptations specific to language. Our uniquely cooperative social system requires sophisticated language skills. Learning and performance of some culturally transmitted elements in animals is genetically based, and we give examples of features of human language that evolve slowly enough that genetic adaptations to them may arise.

Language and life history can be related functionally through the study of human ontogeny, thus usefully informing our understanding of several unique aspects of the evolution of species. The operational principles outlined by Locke & Bogin (L&B) demonstrate that the present can provide a useful framework for understanding the past.

The article deals with the notion of the genetic code and its metaphorical understanding as a “language”. In the traditional view of the language metaphor of the genetic code, combinations of nucleotides are signs of amino acids. Similarly, words combined from letters represent certain meanings. The language metaphor of the genetic code, 171–200, 2011) assumes that the nucleotides stay in the analogy to letters, triples to words and genes to sentences. We propose an application (...) of mathematical linguistic methods on the notion of the genetic code. We provide quantitative analysis of mRNA strings and natural language texts. This analysis is sensitive to the detection of the code units hierarchy. We also take into consideration a representative quantitative analysis of DNA, RNA and proteins. Our analysis of mRNA confirms an assumption that the design of the genetic code cannot analogize DNA bases and letters. The notion of the letter is much more appropriate if analogized with triplets or amino acids, 187–191, 2017). (shrink)

The article proposes to further develop the ideas of the Extended Evolutionary Synthesis by including into evolutionary research an analysis of phenomena that occur above the organismal level. We demonstrate that the current Extended Synthesis is focused more on individual traits (genetically or non-genetically inherited) and less on community system traits (synergetic/organizational traits) that characterize transgenerational biological, ecological, social, and cultural systems. In this regard, we will consider various communities that are made up of interacting populations, and for which the (...) individual members can belong to the same or to different species. Examples of communities include biofilms, ant colonies, symbiotic associations resulting in holobiont formation, and human societies. The proposed model of evolution at the level of communities revises classic theorizing on the major transitions in evolution by analyzing the interplay between community/social traits and individual traits, and how this brings forth ideas of top-down regulations of bottom-up evolutionary processes (collaboration of downward and upward causation). The work demonstrates that such interplay also includes reticulate interactions and reticulate causation. In this regard, we exemplify how community systems provide various non-genetic ‘scaffoldings’, ‘constraints’, and ‘affordances’ for individual and sociocultural evolutionary development. Such research complements prevailing models that focus on the vertical transmission of heritable information, from parent to offspring, with research that instead focusses on horizontal, oblique and even reverse information transmission, going from offspring to parent. We call this reversed information transfer the ‘offspring effect’ to contrast it from the ‘parental effect’. We argue that the proposed approach to inheritance is effective for modelling cumulative and distributed developmental process and for explaining the biological origins and evolution of language.

Between 1946 and 1960, a new phenomenon emerged in the field of bacteriology. "Bacterial sex," as it was called, revolutionized the study of genetics, largely by making available a whole new class of cheap, fast-growing, and easily manipulated organisms. But what was "bacterial sex?" How could single-celled organisms have "sex" or even be sexually differentiated? The technical language used in the scientific press -- the public and inalienable face of 20th century science -- to describe this apparently neuter organism (...) was explicit: the cells "copulated," had "intimate contract," "conjugal unions," and engaged in "ménage à trois" relationships. And yet, to describe bacteria as sexually reproducing organisms, the definition of sex itself had to change. Despite manifold contradictions and the availability of alternative language, the notion of sexually active (even promiscuous) single-celled organisms has persisted, even into contemporary textbooks on cell biology and genetics. In this paper I examine the ways in which bacteria were brought into the genetic fold, sexualized, and given gender; I also consider the issues underlying the durability of "bacterial sex.".

Recognizing that all traits are the result of an interaction between genes and environment, I offer a set of criteria for nevertheless making sense of our practice of singling out certain traits as genetic ones, in effect making a distinction between causes and mere conditions. The central criterion is that a trait is genetic if it is genetic differences that make the differences in that trait variable in a given population. A second criterion requires that genetic (...) traits be individuated in a way that matches what some genetic factors cause specifically. Clarifying our causal and classificatory language here can help us to avoid confusions of both theoretical and practical significance. (shrink)

The concept of ‘geneticization’ has been introduced in the scholarly literature to describe the various interlocking and imperceptible mechanisms of interaction between medicine, genetics, society and culture. It is argued that Western culture currently is deeply involved in a process of geneticization. This process implies a redefinition of individuals in terms of DNA codes, a new language to describe and interpret human life and behavior in a genomic vocabulary of codes, blueprints, traits, dispositions, genetic mapping, and a gentechnological (...) approach to disease, health and the body. This article analyses the thesis of ‘geneticization’. Explaining the implications of the thesis, and discussing the critical refutations, it is argued that ‘geneticization’ primarily is a heuristic tool that can help to re-focus the moral debate on the implications of new genetic knowledge towards interpersonal relations, the power of medicine, the cultural context and social constraints, rather than emphasizing issues as personal autonomy and individual rights.

The concept of innateness is used to make inferences between various better-understood properties, like developmental canalization, evolutionary adaptation, heritability, species-typicality, and so on (‘innateness-related properties’). This article uses a recently-developed account of the representational content carried by inheritance systems like the genome to explain why innateness-related properties cluster together, especially in non-human organisms. Although inferences between innateness-related properties are deductively invalid, and lead to false conclusions in many actual cases, where some aspect of a phenotypic trait develops in reliance on (...) a genetic representation it will tend, better than chance, to have many of the innateness-related properties. The account also shows why inferences between innateness-related properties sometimes fail and argues that such inferences are especially misleading when applied to human psychology and behaviour because human psychological development is especially reliant on non-genetic inherited representations.

:This article examines the moralistic language and arguments used in relation to genetics. The focus is on three practices: the claims that there is a duty to know about one’s own genetic makeup, assertions that genetic information should be used to inform reproductive decisions, and the proposition that there are moral reasons to participate in biobank research. With these three, the author contends that there are equally good, if not better, arguments to challenge them from a Millian (...) perspective. Furthermore, especially in the current political climate, there is a need to respect people’s privacy concerns. (shrink)

Many people have argued that the evolution of the human language faculty cannot be explained by Darwinian natural selection. Chomsky and Gould have suggested that language may have evolved as the by-product of selection for other abilities or as a consequence of as-yet unknown laws of growth and form. Others have argued that a biological specialization for grammar is incompatible with every tenet of Darwinian theory – that it shows no genetic variation, could not exist in any (...) intermediate forms, confers no selective advantage, and would require more evolutionary time and genomic space than is available. We examine these arguments and show that they depend on inaccurate assumptions about biology or language or both. Evolutionary theory offers clear criteria for when a trait should be attributed to natural selection: complex design for some function, and the absence of alternative processes capable of explaining such complexity. Human language meets these criteria: Grammar is a complex mechanism tailored to the transmission of propositional structures through a serial interface. Autonomous and arbitrary grammatical phenomena have been offered as counterexamples to the position that language is an adaptation, but this reasoning is unsound: Communication protocols depend on arbitrary conventions that are adaptive as long as they are shared. Consequently, language acquisition in the child should systematically differ from language evolution in the species, and attempts to analogize them are misleading. Reviewing other arguments and data, we conclude that there is every reason to believe that a specialization for grammar evolved by a conventional neo-Darwinian process. (shrink)

From the 1960s, mathematical and computational tools have been developed to arrive at human population trees from various kinds of serological and molecular data. Focusing on the work of the Italian-born population geneticist Luigi Luca Cavalli-Sforza, I follow the practices of tree-building and mapping from the early blood-group studies to the current genetic admixture research. I argue that the visual language of the tree is paralleled in the narrative of the human diasporas, and I show how the tree (...) was actually mapped onto the surface of the earth. This visual and textual structure is mirrored in the liberal discourse of unity in diversity that has been criticized as running counter to the socio-political effects of human population genetics. From this perspective, one may ask how far the phylogenetic diagram in its various forms is a manifestation of the physics of power that according to Michel Foucault consists in mechanisms that analyse distributions, movements, series, combinations, and that uses instruments to render visible, to register, to differentiate and to compare. It is one among other disciplinary technologies that ensure the ordering of human diversity. In the case of intra-human phylogenetic trees, population samples and labels are one issue. Another is that the separated branches seem to show groups of people, who have in reality been interacting and converging, as isolated. Often based on so-called isolated peoples, molecular tree diagrams freeze a hierarchical kinship system that is meant to represent a state before the great historical population movements. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Genetic Testing and Genetic ScreeningPat Milmoe McCarrick (bio)In recent years there has been an enormous expansion in the knowledge that may be gleaned from the testing of an individual's genetic material to predict present or future disability or disease either for oneself or one's offspring. The Human Genome Project, which is currently mapping the entire human gene system, is identifying progressively more genetic sequencing information (...) (see Scope Note 17, The Human Genome Project). Information obtained from genetic testing raises ethical and legal questions about its uses by society. The ethical dilemmas were foreseen two decades ago by bioethicists who asked whether questionable applications could stop "legitimate pursuits" (IV, Gaylin 1972) and whether genetic disease might come to be viewed as "transmissible" in the sense of being contagious (IV, Veatch 1974).Not only has knowledge expanded, but the practice of genetic testing and screening has greatly increased as well. For example, in the case of testing for cystic fibrosis (CF), the U.S. Congress' Office of Technology Assessment (OTA) estimates that instances of screening jumped from 9310 tests in 1991 to 63,000 tests in 1992 (I, OTA [Cystic Fibrosis] 1992). In addition, the OTA estimates that within the next few years, the six million women who become pregnant each year routinely will be informed of available CF carrier tests (I, OTA [Cystic Fibrosis] 1992).Following the recent identification of a gene linked to breast cancer, Dr. Francis Sellers Collins, director of the National Center for Human Genome Research, said that "it is not inconceivable that every woman in America may want to be screened for this gene. The economic, ethical, and counseling issues will be very daunting." Dr. Collins opines that in the near future physical examinations for 18-year-olds will include DNA testing for diseases with genetic components and that physicians, in the interests of preventive medicine, will make risk-based recommendations for a healthy life-style (IV, Breo 1993). The U.S. President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research predicted as early as 1983 that before the end of the century genetic screening and counseling would become major components of both public health and individual medical care (I, U.S. President's Commission 1983). [End Page 333]The OTA defines genetic testing as "the use of specific assays to determine the genetic status of individuals already suspected to be at high risk for a particular inherited condition. The terms genetic test, genetic assay, and genetic analysis are used interchangeably to mean the actual laboratory examination of samples." In contrast, genetic screening usually uses the same assays employed for genetic testing but is distinguished from genetic testing by its target population (I, OTA [Genetic Monitoring] 1990). The National Academy of Sciences (NAS) defines screening as the systematic search of populations for persons with latent, early, or asymptomatic disease (III, NAS 1975). Some of the literature annotated for this Scope Note appears to use the terms "testing" and "screening" interchangeably.Philip Boyle of the Hastings Center points out that the language used to describe genetic variation is important and asks what words should be used: "Defects, flaws, deleterious genes, disorders, or the more neutral conditions? Using words such as normal—and its corollary, abnormal—is likely to foster stigmatization and discrimination" (III, Genetic Grammar, Boyle 1992).Areas of focus in genetic testing include: prenatal diagnosis, newborn screening, carrier screening, forensic screening, and susceptibility screening.Prenatal diagnosis discerns whether a fetus is at risk for various identifiable genetic diseases or traits. Prenatal diagnosis is made using amniotic fluid, fetal cells, and fetal or maternal blood cells obtained during amniocentesis testing; alpha fetoprotein assays or chorionic villus sampling; or ultrasound tomography, which creates fetal images on a screen. Another method, known as fetoscopy, uses a camera on a needle inserted in the uterus to view the fetus. Since prenatal screening began in 1966 (I, U.S. President's Commission 1983), the number of metabolic defects and genetic disorders that can be diagnosed prenatally has expanded greatly. There is also discussion of requiring testing for parents who are participating in an in vitro fertilization program and are at genetic... (shrink)

: New genetic technologies continue to emerge that allow us to control the genetic endowment of future children. Increasingly the claim is made that it is morally "irresponsible" for parents to fail to use such technologies when they know their possible children are at risk for a serious genetic disorder. We believe such charges are often unwarranted. Our goal in this article is to offer a careful conceptual analysis of the language of irresponsibility in an effort (...) to encourage more care in its use. Two of our more important sub-claims are: A fair judgment of genetic irresponsibility necessarily requires a thick background description of the specific reproductive choice; and there is no necessary connection between an act's being morally wrong and its being irresponsible. These are distinct judgments requiring distinct justifications. (shrink)

This is the third edition of Chomsky's outstanding collection of essays on language and mind, first published in 2006. The first six chapters, originally published in the 1960s, made a groundbreaking contribution to linguistic theory. This edition complements them with an additional chapter and a new preface, bringing Chomsky's influential approach into the twenty-first century. Chapters 1-6 present Chomsky's early work on the nature and acquisition of language as a genetically endowed, biological system, through the rules and principles (...) of which we acquire an internalized knowledge. Over the past fifty years, this framework has sparked an explosion of inquiry into a wide range of languages, and has yielded some major theoretical questions. The final chapter revisits the key issues, reviewing the 'biolinguistic' approach that has guided Chomsky's work from its origins to the present day, and raising some novel and exciting challenges for the study of language and mind.

According to Bickerton, the behavioral sciences have failed to give an adequate account of human nature at least partly because of the conjunction and mutual reinforcement of two widespread beliefs: that language is simply a means of communication and that human intelligence is the result of the rapid growth and unusual size of human brains. Bickerton argues that each of the properties distinguishing human intelligence and consciousness from that of other animals can be shown to derive straightforwardly from properties (...) of language. In essence, language arose as a representational system, not a means of communication or a skill, and not a product of culture but an evolutionary adaptation. The author stresses the necessity of viewing intelligence in evolutionary terms, seeing it not as problem solving but as a way of maintaining homeostasis - the preservation of those conditions most favorable to an organism, the optimal achievable conditions for survival and well-being. The term protolanguage is used to describe the stringing together of symbols that prehuman hominids employed. "It did not allow them to turn today's imagination into tomorrow's fact. But it is just this power to transform imagination into fact that distinguishes human behavior from that of our ancestral species, and indeed from that of all other species. It is exactly what enables us to change our behavior, or invent vast ranges of new behavior, practically overnight, with no concomitant genetic changes." Language and Human Behavior should be of interest to anyone in the behavioral and evolutionary sciences and to all those concerned with the role of language in human behavior. (shrink)

The question of whether “genetic information” is a merely causal factor in development or can be made sense of semantically, in a way analogous to a language or other type of representation, has generated a long debate in the philosophy of biology. It is intimately connected with another intense debate, concerning the limits of genetic determinism. In this paper I argue that widespread attempts to draw analogies between genetic information and information contained in books, blueprints or (...) computer programs, are fundamentally inadequate. In development, gene exons are the central part of an intricate and densely ramified semantic Genetic Informational Network. DNA in the entire genome is in a state of continuous positive and negative feedback with itself and with its ‘environment’, and is ‘read’ and acted upon by the cell in various alternative and complementary ways. The linear combinatorial coding relation between codons and amino acids is but one aspect of semantic genetic information, which is, when considered in its entirety, a far wider and richer concept.

In the history of genetics, the information-theoretical description of the gene, beginning in the early 1960s, had a significant effect on the concept of the gene. Information is a highly complex metaphor which is applicable in view of the description of substances, processes, and spatio-temporal organisation. Thus, information can be understood as a functional particle of many different language games (some of them belonging to subdisciplines of genetics, as the biochemical language game, some of them belonging to linguistics (...) and informatics). It is this wide covering of different language games that justifies the common description of genes x, y, z as containing information for the phenotypic traits X, Y, Z (or the genome as storage for the information of a whole organism). However, if information is taken as the explanans and phenotypic traits or organisms as the explananda, then a description of the explanandum is of prior importance before the explanans can be characterised. This way of thinking could be useful for future discussions on the strikingly dominant information -metaphor, and the different gene concepts as well. The article illustrates this in two steps. First, a condensed overview on the history of genetics is given, which can be divided into three parts: (1) genetics without genes, (2) genetics with genes, but without information, (3) genetics with genes and information. It is assumed that this provides not only some historical knowledge about the origin of genetics and the introduction of technical terms, but offers at least preliminary insight into the methodological structure of genetic descriptions. In a second step, we redraw Spemann’s disturbation experiments to discuss our thesis that genetic information is not a natural entity, but part of a causality-language game which is secondarily added to the descriptions of interventionalistic practices, viz. experimental approaches.

Creating Future People offers readers a fast-paced primer on how new genetic technologies will enable parents to influence the traits of their children, including their intelligence, moral capacities, physical appearances, and immune systems. It deftly explains the science of gene editing and embryo selection, and raises the central moral questions with colorful language and a brisk style. Jonathan Anomaly takes seriously the diversity of preferences parents have, and the limits policymakers face in regulating what could soon be a (...) global market for reproductive technology. He argues that once embryo selection for complex traits happens it will change the moral landscape by altering the incentives available to parents. All of us will take an interest in the traits everyone else selects, and this will present coordination problems that previous writers on genetic enhancement have failed to consider. Anomaly navigates difficult ethical issues with vivid language and scientifically-informed speculation about how genetic engineering will transform humanity. Key Features: Offers clear explanations of scientific concepts Explores important moral questions without academic jargon Brings discoveries from different fields together to give us a sense of where humanity is headed.

It is widely assumed that human learning and the structure of human languages are intimately related. This relationship is frequently suggested to derive from a language-specific biological endowment, which encodes universal, but communicatively arbitrary, principles of language structure (a Universal Grammar or UG). How might such a UG have evolved? We argue that UG could not have arisen either by biological adaptation or non-adaptationist genetic processes, resulting in a logical problem of language evolution. Specifically, as the (...) processes of language change are much more rapid than processes of genetic change, language constitutes a both over time and across different human populations, and, hence, cannot provide a stable environment to which language genes could have adapted. We conclude that a biologically determined UG is not evolutionarily viable. Instead, the original motivation for UG arises because language has been shaped to fit the human brain, rather than vice versa. Following Darwin, we view language itself as a complex and interdependent which evolves under selectional pressures from human learning and processing mechanisms. That is, languages themselves are shaped by severe selectional pressure from each generation of language users and learners. This suggests that apparently arbitrary aspects of linguistic structure may result from general learning and processing biases deriving from the structure of thought processes, perceptuo-motor factors, cognitive limitations, and pragmatics.

This article sets out to show that Wittgenstein and Freud have exerted a considerable - though narrow - influence on Bourdieu’s sociology. But their influence also pervades the theoretical development of two other currents that have emerged in French sociology in the last few years, and that were developed by L. Boltanski and L. Thévenot on the one hand, and B. Lahire on the other. Although they do not make it explicit, the advocates of these two currents have nevertheless been (...) influenced by Wittgenstein and Freud. Thus Boltanski has drawn on Wittgenstein to develop a sociology which gives primacy to the social actor’s interpretation of his or her situation through lay theorizing. Lahire’s work clearly pays a debt to Freud with his psychological sociology. It would therefore be interesting, in the first instance, to tease out how Wittgenstein and Freud, respectively, have influenced these two systems to demonstrate that they can indeed be used to generate new sociological currents, other than Bourdieu’s own. This would then allow us to explore how they could be used to fill any gaps in Bourdieu’s work, thus giving the latter renewed relevance and staunching its stagnating tendencies. Ultimately, this analysis aims to show how Wittgenstein’s and Freud’s theoretical influences can lead the way towards a theoretical synthesis between Bourdieu’s critical sociology, Boltanski’s social actor theory and Lahire’s psychological sociology. Currently, these three currents operate independently of each other, without any kind of dialogue. And yet, far from being incompatible, these sociologies offer opportunities for exploring how they might complement and mutually enrich each other. (shrink)

It is customary to apply the term “ideology” to political statements and statements about politics believed to be saturated with irrational elements. Since more often than not it is applied to the political science and policies of parties of the extreme, one may suspect that this usage is itself colored by political interests. However, “ideology” can be redefined at the level of a meta-science that reduces, though it cannot altogether eliminate, the partisan function of language about politics. Ideological thinking (...) can then be shown to involve a logical error that is the counterpart of the genetic fallacy. Surprisingly, in this usage liberal political science, or that with liberal preconceptions, is a more frequent offender against the logic of science than a science of politics with illiberal preconceptions.

Language does not fossilize but this does not mean that the language's evolutionary timeline is lost forever. Great apes provide a window back in time on our last prelinguistic ancestor's communication and cognition. Phylogeny and cladistics implicitly conjure Pan (chimpanzees, bonobos) as a superior (often the only) model for language evolution compared with earlier diverging lineages, Gorilla and Pongo (orangutans). Here, in reviewing the literature, it is shown that Pan do not surpass other great apes along (...) class='Hi'>genetic, cognitive, ecologic, or vocal traits that are putatively paramount for language onset and evolution. Instead, revived herein is the idea that only by abandoning single‐species models and learning about the variation among great apes, there might be a chance to retrieve lost fragments of the evolutionary timeline of language.

The main purpose of this article is to consider the significance of different types of memory and non-genetic inheritance and different biosemiotic systems for the origin and evolution of language. It presents language and memory as distributed, heteronomous and system-determined processes implemented in biological and social domains. The article emphasises that language and other sign systems are both ecological and inductive systems that were caused by and always correlate with the environment and deductive systems that are (...) inherited by and depend on the internal development of organisms, individuals, and societies. The article also claims that the origin, re-occurrence and evolution of naturally-emerging sign systems presuppose their retention and accumulation in physical, biological, individual, and social types of memory and reinforcement and maintenance by conventional and deliberate social regulation and accumulation. All of this allows language and other sign systems to be situation-relevant and to be transmitted through generations without their constant reinvention. The novelty of the proposed theory of language origin and evolution is in interdisciplinary integration of biosemiotic studies, systems approaches to language and studies of inheritance systems presented by ‘Extended evolutionary synthesis’.

In the generative tradition, the language faculty has been shrinking—perhaps to include only the mechanism of recursion. This paper argues that even this view of the language faculty is too expansive. We first argue that a language faculty is difficult to reconcile with evolutionary considerations. We then focus on recursion as a detailed case study, arguing that our ability to process recursive structure does not rely on recursion as a property of the grammar, but instead emerge gradually (...) by piggybacking on domain-general sequence learning abilities. Evidence from genetics, comparative work on non-human primates, and cognitive neuroscience suggests that humans have evolved complex sequence learning skills, which were subsequently pressed into service to accommodate language. Constraints on sequence learning therefore have played an important role in shaping the cultural evolution of linguistic structure, including our limited abilities for processing recursive structure. Finally, we re-evaluate some of the key considerations that have often been taken to require the postulation of a language faculty. (shrink)

Background Genomic research is challenging the tradition of informed consent. Genomic researchers in the USA, Canada and parts of Europe are encouraged to use informed consent to address the prospect of disclosing individual research results (IRRs) to study participants. In the USA, no national policy exists to direct this use of informed consent, and it is unclear how local institutional review boards (IRBs) may want researchers to respond. Objective and methods To explore publicly accessible IRB websites for guidance in this (...) area, using summative content analysis. Findings Three types of research results were addressed in 45 informed consent templates and instructions from 20 IRBs based at centres conducting genomic research: (1) IRRs in general, (2) incidental findings (IFs) and (3) a broad and unspecified category of ‘significant new findings’ (SNFs). IRRs were more frequently referenced than IFs or SNFs. Most documents stated that access to IRRs would not be an option for research participants. These non-disclosure statements were found to coexist in some documents with statements that SNFs would be disclosed to participants if related to their willingness to participate in research. The median readability of template language on IRRs, IFs and SNFs exceeded a ninth-grade level. Conclusion IRB guidance may downplay the possibility of IFs and contain conflicting messages on IRR non-disclosure and SNF disclosure. IRBs may need to clarify why separate IRR and SNF language should appear in the same consent document. The extent of these issues, nationally and internationally, needs to be determined. (shrink)

The role genetic inheritance plays in the way human beings look and behave is a question about the biology of human sexual reproduction, one that scientists connected with the Human Genome Project dashed to answer before the close of the twentieth century. This is also a question about politics, and, it turns out, poetry, because, as the example of Lucretius shows, poetry is an ancient tool for the popularization of science. "Popularization" is a good word for successful efforts to (...) communicate elite science to non-scientists in non-technical languages and media. According to prominent sociobiologist E. O. Wilson, "sexual dominance is a human universal." He meant, of course, that men dominate women. Like sociobiology, genetic science is freighted with politics, including gender politics. Scientists have gender perspectives that may color what they "see" in nature. As the late Susan Okin Miller suggested in an unpublished paper tracing the detrimental impact of Aristotle's teleology on Western thought, scientists accustomed to thinking that men naturally dominate women might interpret genetic discoveries accordingly. Biologists have good, scientific reasons to fight the effects of bias. One must be critical of how scientists and popularizers of science, like "Genome" author Matt Ridley, frame truth and theory. Ridley's "battle of the sexes" metaphor and others have a doubtful place in serious explanations of science. (shrink)

Progress in molecular biology has revealed profound relations between linguistic and genomic sciences, mainly through advances in bioinformatics. The structural symmetries between biochemical and verbal syntaxes raise the question of their origins: did they emerge independently, or did one arise from the other? Does the genetic code contain the traces of a protolanguage, a universal grammar whose gradual evolution and successive mutations progressively led to the polymorphism of natural languages? To explore this question, we review the isomorphism of the (...) genetic code and verbal codes from lexical, syntactic, semantic and pragmatic standpoints. We discuss the limits of these symmetries and their anthropomorphic connotations. We observe the gradual evolution of species and languages according to parallel mechanisms, and the genetic roots of the physiology of language. In conclusion, we hypothesize that human observers may not be projecting linguistic frameworks onto genomic structures. Rather, it could be their linguistic faculties that reflect the grammatical structure of genetic code. (shrink)
