Isochrony is crucial to the rhythm of human music. Some neural, behavioral and anatomical traits underlying rhythm perception and production are shared with a broad range of species. These may either have a common evolutionary origin, or have evolved into similar traits under different evolutionary pressures. Other traits underlying rhythm are rare across species, only found in humans and few other animals. Isochrony, or stable periodicity, is common to most human music, but isochronous behaviors are also found in many species. (...) It appears paradoxical that humans are particularly good at producing and perceiving isochronous patterns, although this ability does not conceivably confer any evolutionary advantage to modern humans. This article will attempt to solve this conundrum. To this end, we define the concept of isochrony from the present functional perspective of physiology, cognitive neuroscience, signal processing, and interactive behavior, and review available evidence on isochrony in the signals of humans and other animals. We then attempt to resolve the paradox of isochrony by expanding an evolutionary hypothesis about the function that isochronous behavior may have had in early hominids. Finally,we propose avenues for empirical research to examine this hypothesis and to understand the evolutionary origin of isochrony in general. (shrink)

In this revolutionary study of the philosophical problems of language, J.N. Hattiangadi offers a new approach which simultaneously solves several venerable conundrums in the origin and development of language and thought. His argument includes acute criticisms of the later Wittgenstein's theory of language use, Quine's approach to subjunctive conditionals, Kripke's analysis of proper names, and Chomsky's conjecture of an innate universal grammar.

Researchers from diverse disciplines, including organismal and cellular physiology, sports science, human nutrition, evolution and ecology, have sought to understand the causes and consequences of the surprising variation in metabolic rate found among and within individual animals of the same species. Research in this area has been hampered by differences in approach, terminology and methodology, and the context in which measurements are made. Recent advances provide important opportunities to identify and address the key questions in the field. By bringing (...) together researchers from different areas of biology and biomedicine, we describe and evaluate these developments and the insights they could yield, highlighting the need for more standardisation across disciplines. We conclude with a list of important questions that can now be addressed by developing a common conceptual and methodological toolkit for studies on metabolic variation in animals. (shrink)

Different sources of data on the evolution of segmentation lead to very different conclusions. Molecular similarities in the developmental pathways generating a segmented body plan tend to suggest a segmented common ancestor for all bilaterally symmetrical animals. Data from paleontology and comparative morphology suggest that this is unlikely. A possible solution to this conundrum is that throughout evolution there was a parallel co‐option of gene regulatory networks that had conserved ancestral roles in determining body axes and in (...) elongating the anterior‐posterior axis. Inherent properties in some of these networks made them easily recruitable for generating repeated patterns and for determining segmental boundaries. Phyla where this process happened are among the most successful in the animal kingdom, as the modular nature of the segmental body organization allowed them to diverge and radiate into a bewildering array of variations on a common theme.

An exploration of the moral and ethical implications of new biotechnologies Many of the ethical issues raised by new technologies have not been widely examined, discussed, or indeed settled. For example, robotics technology challenges the notion of personhood. Should a robot, capable of making what humans would call ethical decisions, be held responsible for those decisions and the resultant actions? Should society reward and punish robots in the same way that it does humans? Likewise, issues of safety, environmental concerns, and (...) distributive justice arise with the increasing acceptance of genetically modified organisms in food production nanotechnology in engineering and medicine, and human gene therapy and enhancement. The problem of dual-use—when a technology can be used both to benefit and to harm—exists with virtually all new technologies but is central in the context of emerging 21st century technologies ranging from artificial intelligence and robotics to human gene-editing and brain-computer interfacing. In Re-Creating Nature: Science, Technology, and Human Values in the Twenty-First Century, James T. Bradley addresses emerging biotechnologies with prodigious potential to benefit humankind but that are also fraught with ethical consequences. Some actually possess the power to directly alter the evolution of life on earth including human. Specifically, these topics include stem cells, synthetic biology, GMOs in agriculture, nanotechnology, bioterrorism, CRISPR gene-editing technology, three-parent babies, robotics and roboethics, artificial intelligence, and human brain research and neurotechnologies. Offering clear explanations of these various technologies, a pragmatic presentation of the conundrums involved, and questions that illuminate hypothetical situations, Bradley guides discussions of these and other thorny issues resulting from the development of new biotechnologies. He also highlights the responsibilities of scientists to conduct research in an ethical manner and the responsibilities of nonscientists to become “science literate” in the twenty-first century.

Studies with captive fowl have revealed that they possess greater cognitive capacities than previously thought. We now know that fowl have sophisticated cognitive and communicative skills, which had hitherto been associated only with certain primates. Several theories have been advanced to explain the evolution of such complex behavior. Central to these theories is the enlargement of the brain in species with greater mental capacities. Fowl present us with a conundrum, however, because they show the behaviors anticipated by the (...) theories but do not have the expected changes in the brain. Consequently fowl present two challenges of interest to us here. One is a scientific challenge to explain their remarkable capabilities. The other is an ethical challenge regarding our treatment of animals with higher cognitive skills. (shrink)

The fact that all languages known are digital poses the question of their origin. The answer developed here treats language as the interface of information theory and molecular development by showing previously unrecognized isomorphisms between the analog and digital features of language and life at the molecular level. Human language is a special case of signal transduction and hence is subject to the coding aspects of Shannon's theorems and the analog aspects of pattern recognition, each represented by genotype and phenotype. (...) Digital language acquisition is late in evolution and postnatal development and requires a neural reorganization by a mechanism of somatic network programming in response to the environment. Such a mechanism would solve the Chomsky conundrum of how children can learn any language without knowing rules of grammar too numerous to be encoded genotypically.

Stunned by the implications of Colagè's analysis of the cultural activation of the brain's Visual Word Form Area and the potential role of cultural neural reuse in the evolution of biology and culture, the authors build on his work in proposing a context for the first rudimentary hominin moral systems. They cross-reference six domains: neuroscience on sleep, creativity, plasticity, and the Left Hemisphere Interpreter; palaeobiology; cognitive science; philosophy; traditional archaeology; and cognitive archaeology's theories on sleep changes in Homo erectus (...) and consequences for later humans. The authors hypothesize that the human genome, when analyzed with findings from neuroscience and cognitive science, will confirm the evolutionary timing of an internal running monologue and other neural components that constitute moral decision making. The authors rely on practical modern philosophers to identify continuities with earlier primates, and one major discontinuity—some bright white moral line that may have been crossed more than once during the long and successful tenure of Homo erectus on Earth.

In lieu of an abstract, here is a brief excerpt of the content:Instinct of Nature: Natural Law, Synderesis, and the Moral SenseRobert A. Greene“Instinct is a great matter.”—Sir John FalstaffThis essay traces the evolution of the meaning of the expression instinctus naturae in the discussion of the natural law from Justinian’s Digest through its association with synderesis to Francis Hutcheson’s theory of the moral sense. The introduction of instinctus naturae into Ulpian’s definition of the natural law by Isidore of (...) Seville in the seventh century posed a problem of definition for medieval commentators. Some said that it meant a universal and providential natura naturans; some defined it as the urge to self and species preservation in animals, degenerating in man into sensual and shameful impulses; some advanced the humanistic and paradoxical notion that it referred to a unique exercise of human reason in coming to know the natural law. The contemporaneous revival in the twelfth century of St. Jerome’s puzzling new term “synderesis,” and its gradual definition as the immediate apprehension of the first practical moral principles of the natural law, brought the two terms into proximity and loose association.A half-century later St. Bonaventure made explicit what had remained latent in the thinking of Thomas Aquinas by relocating synderesis in the affective rather than the intellectual part of man’s nature. Accordingly the moral discoveries of synderesis came to be spoken of as not only non-discursive but instinctive in nature—apprehensions for which no reason could be given, apprehensions somehow rooted in affective human experience. During the bilingual early modern period an increasingly secularized, internalized, and reified instinctus [End Page 173] naturae, together with its abbreviated vernacular cognate, “instinct,” came to serve as a substitute and synonym for the obsolescent synderesis. Edward Herbert’s attention to instinctus naturae in his De Veritate (1624), Sir Matthew Hale’s speculations about the place of rational instinct in the natural law, and Francis Hutcheson’s theory of a moral sense all exemplify this semantic legacy.The first entry in Justinian’s Digest has had a disproportionate influence on later speculation about the natural law. It begins a chapter that gives pride of place to general definitions of justice, law, jus naturale and jus gentium, and it is drawn from the writings of the Roman jurisconsult Domitius Ulpianus (d. 223), whose work constitutes forty percent of the Digest. Ulpian defines the natural law, with insistent repetition, as that which nature has taught to, or is common to, all animals:Jus naturale is that which nature has taught to all animals; for it is not a law specific to mankind but is common to all animals—land animals, sea animals, and the birds as well. Out of this comes the union of man and woman [male and female] which we call marriage, and the procreation of children, and their rearing. So we can see that the other animals, wild beasts included, are rightly understood to be acquainted with this law. Jus gentium, the law of the nations, is that which all human peoples observe. That it is not coextensive with natural law can be grasped easily, since this latter is common to all animals whereas jus gentium is common only to human beings among themselves. 1Justinian’s compilers gave Ulpian’s definition striking prominence at the beginning of the Digest and then in the same short chapter quoted the incompatible and more traditional definitions of his contemporaries Gaius and Paulus. They confined the operation of the natural law to mankind and spoke of reason as its source. 2 The compilers had been charged to eliminate just such conflicts; yet here at the very outset they set a conundrum that perplexed commentators [End Page 174] and invited explanation from Isidore of Seville to Hugo Grotius. Their selection of quotations suggests that as lawyers they regarded such general definitions as “for legal purposes no more than ornament to discussion.” 3 For those of a more speculative bent, however, the dilemmas could not have been more fundamental. How was the natural law to be defined in relation to those appetitive and self-preservative urges that man seemed to share with animals? Or did the term law apply only... (shrink)

This discussion recounts the development of several anthropological definitions of human nature. It then examines conclusions of studies in other disciplines that make possible a revised empirical definition of human nature and which have led to re-examination of paleoanthropological data classed as unimportant under the rubrics of preceeding studies. Finally, this discussion appraises certain of these data, as they pertain to the question: "Do empirical evidences suggest that a human nature, as well as a human structure, may be the product (...) of evolutionary processes?".

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)

The Linnaean system of classification is a threefold system of theoretical assumptions, sorting rules, and rules of nomenclature. Over time, that system has lost its theoretical assumptions as well as its sorting rules. Cladistic revisions have left it less and less Linnaean. And what remains of the system is flawed on pragmatic grounds. Taking all of this into account, it is time to consider alternative systems of classification.

The role of emergence in the creation of consciousness has been debated for over a century, but it remains unresolved. In particular there is controversy over the claim that a “strong” or radical form of emergence is required to explain phenomenal consciousness. In this paper we use some ideas of complex system theory to trace the emergent features of life and then of complex brains through three progressive stages or levels: Level 1 (life), Level 2 (nervous systems), and Level 3 (...) (special neurobiological features), each representing increasing biological and neurobiological complexity and ultimately leading to the emergence of phenomenal consciousness, all in physical systems. Along the way we show that consciousness fits the criteria of an emergent property—albeit one with extreme complexity. The formulation Life + Special neurobiological features → Phenomenal consciousness expresses these relationships. Then we consider the implications of our findings for some of the philosophical conundrums entailed by the apparent “explanatory gap” between the brain and phenomenal consciousness. We conclude that consciousness stems from the personal life of an organism with the addition of a complex nervous system that is ideally suited to maximize emergent neurobiological features and that it is an example of standard (“weak”) emergence without a scientific explanatory gap. An “experiential” or epistemic gap remains, although this is ontologically untroubling. (shrink)

This book is the first volume on the evolution of wisdom. Using a combination of ethnographic and ethological studies, it shows how key moral attributes of compassion, justice and wisdom are woven into relationships with animals.

essay on Robert Brandom, Making it Explicit.

I show that there is a link between the evolution of organisms and the evolution of ideas. In particular, if conformity is selected for, then mechanisms are needed so that “mutations” of ideas can occur. Creativity acts as a counter-force to conventional intelligence, so that ideas can develop that do not just elaborate existing paradigms, but oppose these paradigms. Sometimes oppositional ideas go too far, however, and wisdom acts as a force to bring the old and the new (...) together. The dialectic thus integrates intelligence, creativity, and wisdom, with intelligence serving as thesis, creativity as antithesis, and wisdom as synthesis. (shrink)

One of the most interesting challenges facing paleobiologists is explaining the Cambrian explosion, the dramatic appearance of most metazoan animal phyla in the Early Cambrian, and the subsequent stability of these body plans over the ensuing 530 million years. We propose that because phenotypic variation decreases through geologic time, because microRNAs (miRNAs) increase genic precision, by turning an imprecise number of mRNA transcripts into a more precise number of protein molecules, and because miRNAs are continuously being added to metazoan genomes (...) through geologic time, miRNAs might be instrumental in the canalization of development. Further, miRNAs ultimately allow for natural selection to elaborate morphological complexity, because by reducing gene expression variability, miRNAs increase heritability, allowing selection to change characters more effectively. Hence, miRNAs might play an important role in shaping metazoan macroevolution, and might be part of the solution to the Cambrian conundrum. (shrink)

In a series of three articles, presented at the Goshen Annual Conference on Science and Religion in 2015, with the theme ‘Interdisciplinary Theology and the Archeology of Personhood’, J. Wentzel van Huyssteen considers the problem of human evolution – also referred to as ‘the archaeology of personhood’ – and its broader impact on theological anthropology. This trajectory of lectures tracks a select number of challenging contemporary proposals for the evolution of crucially important aspects of human personhood. These are (...) aspects that were all of great significance for Darwin: the evolution of cognition, the evolution of imagination, music and language, the evolution of morality, and the evolution of the religious disposition.

The article discusses possible ways of overcoming the environmental crisis. It is based on Šmajs’ evolutionary ontological understanding of the environmental crisis of nature, which distinguishes between natural and cultural evolution and demonstrates the opposing relationships between them. It critically develops one of Šmajs’ proposals for initiating a biophilic transformation of culture by dealing with some of the consequences of the economic crisis (specifically unemployment).

From an evolutionary standpoint, a default presumption is that true beliefs are adaptive and misbeliefs maladaptive. But if humans are biologically engineered to appraise the world accurately and to form true beliefs, how are we to explain the routine exceptions to this rule? How can we account for mistaken beliefs, bizarre delusions, and instances of self-deception? We explore this question in some detail. We begin by articulating a distinction between two general types of misbelief: those resulting from a breakdown in (...) the normal functioning of the belief formation system (e.g., delusions) and those arising in the normal course of that system's operations (e.g., beliefs based on incomplete or inaccurate information). The former are instances of biological dysfunction or pathology, reflecting “culpable” limitations of evolutionary design. Although the latter category includes undesirable (but tolerable) by-products of “forgivably” limited design, our quarry is a contentious subclass of this category: misbeliefs best conceived as design features. Such misbeliefs, unlike occasional lucky falsehoods, would have been systematically adaptive in the evolutionary past. Such misbeliefs, furthermore, would not be reducible to judicious – but doxastically1noncommittal – action policies. Finally, such misbeliefs would have been adaptive in themselves, constituting more than mere by-products of adaptively biased misbelief-producing systems. We explore a range of potential candidates for evolved misbelief, and conclude that, of those surveyed, onlypositive illusionsmeet our criteria. (shrink)

I examine Michael Oakeshott's theory of modes of experience in light of today's evolution debates and argue that in much of our current debate science and religion irrelevantly attack each other or, less commonly but still irrelevantly, seek out support from the other. An analysis of Oakeshott's idea of religion finds links between his early holistic theory of the state, his individualistic account of religious sensibility, and his theory of political, moral, and religious authority. Such analysis shows that a (...) modern individualistic theory of the state need not be barrenly secular and suggests that a religious sensibility need not be translated into an overmastering desire to use state power to pursue moral or spiritual ends in politics. Finally, Oakeshott's vision of a civil conversation, as both a metaphor for Western civilization and as a quasi-ethical ideal, shows us how we might balance the recognition of diverse modal truths, the pursuit of singular religious or philosophic truth, and a free political order.

The law of coherence helps us understand the physical force behind the increasing complexity of the evolutionary process, from quanta, to cells, to self-awareness and collective consciousness. The coherent electromagnetic field is the inner glue of every system, the "intelligent" energy-information communication that assures a cooperative and synergic behavior to all the components of the system, as a whole, allowing harmonious evolution and unity of consciousness. Neuropsychological experiments show that the different brain areas communicate with more or less coherence (...) according to different states of consciousness: high values are correlated with states of psychophysical integrity and well-being, whereas low values with states of conflict and depression. If we expand isomorphically these brain discoveries, we will have four main general states of coherence: from disgregation to unity, which represents an important element, in the General System Theory, to differentiate between inanimate and animate system, and to understand how billions cells become a single living organism, and then how billions of human beings could eventually generate planetary consciousness. In this light the resolution of the global ecosystem crisis implicates human transformation from a low to a highly coherent state of consciousness. The key to the entire process seems to be the coherent nature of consciousness. (shrink)

A number of animal species from different lineages live socially. One of the features of social living is the formation of dominance hierarchy. Despite its obvious benefit in the survival probability of the species, the hierarchical structureitself poses psychological and physiological burden leading to the chronic activation of stress related pathways. Considering these apparently conflicting observations, here we propose that social hierarchy can act as a selective force in the evolution of social species. We also discuss its role on (...) social psychology. (shrink)

Well before patient-centered or patient-controlled research became trendy, and earlier than calls to preferentially refer to research subjects as participants, Bob Veatch wrote “The Patient as Partner” Veatch presciently argued that research patients should not be thought of as passive subjects nor material from which to obtain data, but rather as partners in discovery. In this manuscript, I will explore Veatch’s conception of patient as partner in research and how that idea has evolved and been implemented over time and consider (...) some of the remaining challenges. Complexities of patient partnership include: clarifying the types of research in which patient partnership is most appropriate, recognizing the various possible levels of patient engagement in each case, avoiding tokenism and striving for respectful partnership, and keeping in mind the appropriate implementation of protections and safeguards. Bob Veatch would be pleased with the progress that has been made in creating research partnerships with patients, while also undoubtedly pushing us to continue to do better. (shrink)

The purely theoretical notion of fitness or optimality that is employed for instance in optimization theory has come under attack from those who think that only a more historically based notion of fitness could have a central role in evolutionary explanation. They argue that the key notion is proven usefulness rather than theoretical usefulness. This paper articulates a notion of theoretical usefulness and defends its role in functional evolutionary explanations.

While influential works since the 1970s have widely assumed that imitation is an innate skill in both human and non-human primate neonates, recent empirical studies and meta-analyses have challenged this view, indicating other forms of reward-based learning as relevant factors in the development of social behavior. The visual input translation into matching motor output that underlies imitation abilities instead seems to develop along with social interactions and sensorimotor experience during infancy and childhood. Recently, a new visual stream has been identified (...) in both human and non-human primate brains, updating the dual visual stream model. This third pathway is thought to be specialized for dynamics aspects of social perceptions such as eye-gaze, facial expression and crucially for audio-visual integration of speech. Here, we review empirical studies addressing an understudied but crucial aspect of speech and communication, namely the processing of visual orofacial cues and its integration with vocal auditory cues. Along this review, we offer new insights from our understanding of speech as the product of evolution and development of a rhythmic and multimodal organization of sensorimotor brain networks, supporting volitional motor control of the upper vocal tract and audio-visual voices-faces integration.

SummaryThe meaning of prebiotic evolution is first considered and analysed. The conclusion reached is that the phenomenon is both universal and predetermined, bringing interstellar molecules to the stage of proteins and DNA.Two important properties of living beings, evolution and senescence, are also discussed in depth from a new viewpoint.From this, dialectically, it is suggested that the first of the two phenomena corresponds to a progressive increase in the molecular weight of DNA, whereas the second is dependent on a (...) decrease in this.The theory on which the present research is based is in contradiction to that of the neo‐Darwinists.
