The Reign of Quantity gives a concise but comprehensive view of the present state of affairs in the world, as it appears from the point of view of the 'ancient wisdom', formerly common both to the East and to the West, but now almost entirely lost sight of. The author indicates with his fabled clarity and directness the precise nature of the modern deviation, and devotes special attention to the development of modern philosophy and science, and to the part played (...) by them, with their accompanying notions of progress and evolution, in the formation of the industrial and democratic society which we now regard as 'normal'. Guénon sees history as a descent from Form (or Quality) toward Matter (or Quantity); but after the Reign of Quantity-modern materialism and the 'rise of the masses'-Guénon predicts a reign of 'inverted quality' just before the end of the age: the triumph of the 'counter-initiation', the kingdom of Antichrist. This text is considered the magnum opus among Guénon's texts of civilizational criticism, as is Symbols of Sacred Science among his studies on symbols and cosmology, and Man and His Becoming according to the Vedanta among his more purely metaphysical works.

Le but de cet article est de présenter quelques considérations sur les relations temporelles, stratigraphiques et épistémologiques entre la surface archéologique (et les matériels céramiques collectés pendant les prospections) et les niveaux souterrains (avec leur potentiel informatif). Il ne s’agit pas donc d’une étude archéologique spécifique ou de la discussion d’un problème méthodologique. Mais plutôt d’une réflexion sur les contradictions implicites à certaines approches archéologiques : la lecture linéaire du temps et des évolutions, l’application de notions typiquement occidentales (bien (...) qu’utiles) à des contextes non-occidentaux, ainsi que l’absence d’intérêt archéologique pour la culture matérielle actuelle (sur la surface). La temporalité traditionnelle et linéaire (fondée sur la notion d’une Grande Fracture entre passé et présent, antiquité et « modernité »), est strictement liée aux postulats d’un évolutionnisme linéaire d’empreinte coloniale et crée des apories archéologiques qui peuvent être dépassées par l’adoption d’une temporalité non-linéaire et « aplatie ». Des exemples archéologiques sont brièvement présentés pour montrer le caractère souvent non linéaire des transformations techniques et culturelles et comment la culture matérielle du présent peut être approchée par des méthodes strictement archéologiques.

Cet article analyse les évolutions des positions de Marx à propos de la colonisation. Il souligne tout d’abord l’invariant de ces réflexions : la dénonciation de la violence coloniale. Au départ, on trouve une interprétation de la colonisation comme processus de modernisation, puis comme dynamique de destruction-régénération, liée à l’« unification du monde ». L’auteur identifie spécialement les inflexions successives de la pensée de Marx – résolument critique –, au sujet des questions coloniale et nationale, du caractère non linéaire (...) de l’histoire, mais aussi de la différenciation des formations sociales.

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.

A widely accepted tenet of evolutionary biology is that spontaneous mutations occur randomly with regard to their fitness effect. However, since the mutation rate varies along a genome and this variation can be subject to selection, organisms might evolve lower mutation rates at loci where mutations are most deleterious or increased rates where mutations are most needed. In fact, mechanisms of targeted hypermutation are known in organisms ranging from bacteria to humans. Here we review the main forces driving the evolution (...) of local mutation rates and identify the main limiting factors. Both targeted hyper‐ and hypomutation can evolve, although the former is restricted to loci under very frequent positive selection and the latter is severely limited by genetic drift. Nevertheless, we show how an association of repair with transcription or chromatin‐associated proteins could overcome the drift limit and lead to non‐random hypomutation along the genome in most organisms.Editor's suggested further reading in BioEssays Stress‐induced mutation via DNA breaks in Escherichia coli: A molecular mechanism with implications for evolution and medicine Abstract.

The field of language evolution has recently made Gricean pragmatics central to its task, particularly within comparative studies between human and non-human primate communication. The standard model of Gricean communication requires a set of complex cognitive abilities, such as belief attribution and understanding nested higher-order mental states. On this model, non-human primate communication is then of a radically different kind to ours. Moreover, the cognitive demands in the standard view are also too high for human infants, who nevertheless do engage (...) in communication. In this paper I critically assess the standard view and contrast it with an alternative, minimal model of Gricean communication recently advanced by Richard Moore. I then raise two objections to the minimal model. The upshot is that this model is conceptually unstable and fails to constitute a suitable alternative as a middle ground between full-fledged human communication and simpler forms of non-human animal communication.

En 1893, « physicien-ingénieur » André Blondel invente l’oscillographe bifilaire permettant de visualiser les tensions et courants variables. À l’aide de ce puissant moyen d’investigation, il entreprend tout d’abord l’étude des phénomènes de l’arc électrique alors utilisé pour l’éclairage côtier et urbain puis de l’arc chantant employé comme émetteur d’ondes radioélectriques en T.S.F. En 1905, il met en évidence un nouveau type d’oscillations non-sinusoïdales au sein de l’arc chantant. Vingt ans plus tard, Balthasar Van der Pol reconnaitra qu’il s’agissait en (...) réalité d’oscillations de relaxation. Pour expliquer ce phénomène, il fait appel à une representation dans le plan de phase et montre que son évolution prend la forme de petits cycles. Pendant le premier conflit mondial la triode remplace peu à peu l’arc chantant dans les systèmes de transmission. Au sortir de la guerre, Blondel transpose à la triode la plupart de ses résultats par analogie avec l’arc chantant. En avril 1919, il publie un long mémoire dans lequel il introduit la terminologie « oscillations auto- entretenues » et propose d’illustrer ce concept à partir de l’exemple du vase de Tantale qui sera ensuite repris par Van der Pol et par Philippe Le Corbeiller. Il fournit alors une définition d’un système auto-entretenu assez proche de celles qui seront données par la suite par Aleksandr’ Andronov et Van der Pol. Pour étudier la stabilité des oscillations entretenues par la triode et par l’arc chantant il utilise cette fois une représentation dans le plan complexe et explicite l’amplitude en coordonnées polaires. Il justifie alors l’entretien des oscillations par l’existence de cycles qui présentent presque toutes les caractéristiques des cycles limites de Poincaré. Enfin, en novembre 1919, Blondel réalise, un an avant Van der Pol, la mise en équation des oscillations d’une triode. En mars 1926, Blondel établit l’équation différentielle caractérisant les oscillations de l’arc chantant, en tous points similaire à celle qu’obtient concomitamment Van der Pol pour la triode. Ainsi, tout au long de sa carrière, Blondel, a apporté une contribution fondamentale et relativement méconnue à l’élaboration de la théorie des oscillations non linéaires. L’objet de cet article est donc d’analyser ses principaux travaux dans ce domaine et de mesurer leur importance, voire leur influence en les replaçant dans la perspective du développement de cette théorie.

In the first part I argue that normic laws are the phenomenological laws of evolutionary systems. If this is true, then intuitive human reasoning should be fit in reasoning from normic laws. In the second part I show that system P is a tool for reasoning with normic laws which satisfies two important evolutionary standards: it is probabilistically reliable, and it has rules of low complexity. In the third part I finally report results of an experimental study which demonstrate that (...) intuitive human reasoning is in well accord with basic argument patterns of system P. (shrink)

In this work we present a dynamical approach to quantum logics. By changing the standard formalism of quantum mechanics to allow non-Hermitian operators as generators of time evolution, we address the question of how can logics evolve in time. In this way, we describe formally how a non-Boolean algebra may become a Boolean one under certain conditions. We present some simple models which illustrate this transition and develop a new quantum logical formalism based in complex spectral resolutions, a notion that (...) we introduce in order to cope with the temporal aspect of the logical structure of quantum theory.

The set of design features developed by Charles Hockett in the 1950s and 1960s remains probably the most influential means of juxtaposing animal communication with human language. However, the general theoretical perspective of Hockett is largely incompatible with that of modern language evolution research. Consequently, we argue that his classificatory system—while useful for some descriptive purposes—is of very limited use as a theoretical framework for evolutionary linguistics. We see this incompatibility as related to the ontology of language, i.e. deriving from (...) Hockett’s interest in language as a product rather than a suite of sensorimotor, cognitive and social abilities that enable the use but also acquisition of language by biological creatures. After a reconstruction of Hockett’s views on design features, we raise two criticisms: focus on the means at the expense of content and focus on the code itself rather than the cognitive abilities of its users. Finally, referring to empirical data, we illustrate some of the problems resulting from Hockett’s approach by addressing three specific points—namely arbitrariness and semanticity, cultural transmission, and displacement—and show how the change of perspective allows to overcome those difficulties.

Abstract: I address the issue of how pretence emerged in evolution by reviewing the (mostly negative) evidence about pretend behaviour in non-human primates, and proposing a model of the type of information processing abilities that humans had to evolve in order to be able to pretend. Non-human primates do not typically pretend: there are just a few examples of potential pretend actions mostly produced by apes. The best, but still rare, examples are produced by so-called 'enculturated' apes (reared by humans) (...) and among them specially those that have been systematically trained to use symbols (so-called 'linguistic' apes). A hypothesis that would explain the lack of pretence in apes is that they lack the mentalistic ability of theory of mind. However, in the last years apes have been demonstrated to possess relatively sophisticated social cognitive skills, some of them ontogenetically appearing in humans alongside with or even after pretend play. As a solution to the paradox, I discuss a model according to which pretence is supported by a mechanism capable of computing intentional relations with non-existing objects or properties (Intentional non-existence), as opposed to mechanisms computing intentional relations with existing, although not necessarily currently perceived, objects (Intentional availability). Apes possess the latter, which allows them to solve a variety of theory of mind tasks, but not the former, which typically prevents them from developing pretence. (shrink)

Recently philosophers of biology have argued over whether or not Newtonian mechanics provides a useful analogy for thinking about evolutionary theory. For philosophers, the canonical presentation of this analogy is Sober's. Matthen and Ariew and Walsh, Lewins, and Ariew argue that this analogy is deeply wrong-headed. Here I argue that the analogy is indeed useful, however, not in the way it is usually interpreted. The Newtonian analogy depends on having the proper analogue of Newton's First Law. That analogue is what (...) McShea and Brandon call the Zero Force Evolutionary Law. According to the ZFEL, change, not stasis, is the default state of evolutionary systems. (shrink)

Genome complexity is correlated with biological complexity. A recent paper by Michael Lynch proposes that evolution of complex genomic architecture was driven primarily by non‐adaptive stochastic forces, rather than by adaptive evolution.1 A general negative relationship between selection efficiency and genome complexity provides a strong support for this hypothesis. The broad capacity of this theory is both its appeal and source for criticism. BioEssays 28: 979–982, 2006. © 2006 Wiley Periodicals, Inc.

A replicator is simply something that makes copies of itself. There are hypothetical replicators (e.g., self-catalyzing chemical cycles) that are suspected to be unable to exhibit heritable variation. Variation in any of their constituent molecules would not lead them to produce offspring with those new variant molecules. Copying, such as in DNA replication or in xerox machines, allows any sequence to be remade and then sequence variations to be inherited. This distinction has been used against non-RNA-world hypotheses: without RNA replication (...) systems have no capacity to exhibit heritable variation. However, is copying the only way to have heritable variation? This article suggests that evolution can happen without anything being copied and that, in fact, RNA copying is too complex to arise spontaneously as the first pre-biotic system. There would then be a historical gradation of systems from non-alive to alive in which the capacity to have heritable changes would progressively increase and in which copying, as in template-based RNA-replication, would be a crucial but relatively late event. In addition, this article proposes a way by which RNA replication could have arisen, after systems able to evolve arose, as a crucial innovation and how that innovation spread over existing evolutionary systems and became a major driver of subsequent evolution.

Over forty years have passed since the death of Jean-Paul Sartre, still, his oeuvre stands out as a paramount achievement in existential-phenomenological thought. Among the numerous ideas and challenges he offered to contemporary continental philosophy, the problem of authenticity deserves a special place, for it connects many of existentialism’s key concerns. The ever reforming conceptualization of authenticity had spread from the mid-1930s (La transcendance de l’égo) till Sartre’s posthumously published Cahiers pour une morale that appeared in the early 1980s, and (...) it had a profound impact not only on ethical and literary theories, but also on psychiatry and psychotherapy. The present essay’s undertaking is to closely follow the trajectory of this celebrated concept, to contextualize its development in accordance with Sartre’s shifting philosophical as well as ethical projects over the years, and to point out some of the affinities this concept might have with East Asian thought, and with Buddhism in particular.

In the earlier literature the importance of public policies and regulatory changes to firm performance and competitive position has been well established (e.g., Bonardi, 2004). However, little research has been done on the dynamics of this relationship. In this paper, we examine how and why regulatory changes can affect on the evolution of market and nonmarket strategies of a firm. We use a longitudinal case study on Finnish retail industry to illustrate the interactions between regulatory change, strategic responses and firm (...) performance. (shrink)

In his recent book The Natural Selection of Autonomy, Bruce Waller defends a view that he calls “natural autonomy.” This view holds that human beings possess a kind of autonomy that we share with nonhuman animals, a capacity to explore alternative courses of action, but an autonomy that cannot support moral responsibility. He also argues that this natural autonomy can provide support for the ethical principle of noninterference. I argue that to support the ethical principle of noninterference Waller needs either (...) a libertarian or a compatibilist theory of autonomy. I then go on to argue that, contra Waller, the libertarian view is both compatible with Darwinism and able to make sense of how autonomous acts belong to the agents who perform them. Thus, I conclude that the libertarian position is a live option for Darwinians. If however, naturalism is taken to include a deterministic view of the universe (at least at the nonquantum level), as is often the case, then my article takes some strides in defending “Darwinian non–naturalism.”.

In the context of life sciences, we are constantly confronted with information that possesses precise semantic values and appears essentially immersed in a specific evolutionary trend. In such a framework, Nature appears, in Monod’s words, as a tinkerer characterized by the presence of precise principles of self-organization. However, while Monod was obliged to incorporate his brilliant intuitions into the framework of first-order cybernetics and a theory of information with an exclusively syntactic character such as that defined by Shannon, research advances (...) in recent decades have led not only to the definition of a second-order cybernetics but also to an exploration of the boundaries of semantic information. As H. Atlan states, on a biological level "the function self-organizes together with its meaning". Hence the need to refer to a conceptual theory of complexity and to a theory of self-organization characterized in an intentional sense. There is also a need to introduce, at the genetic level, a distinction between coder and ruler as well as the opportunity to define a real software space for natural evolution. The recourse to non-standard model theory, the opening to a new general semantics, and the innovative definition of the relationship between coder and ruler can be considered, today, among the most powerful theoretical tools at our disposal in order to correctly define the contours of that new conceptual revolution increasingly referred to as metabiology. This book focuses on identifying and investigating the role played by these particular theoretical tools in the development of this new scientific paradigm. Nature "speaks" by means of mathematical forms: we can observe these forms, but they are, at the same time, inside us as they populate our organs of cognition. In this context, the volume highlights how metabiology appears primarily to refer to the growth itself of our instruments of participatory knowledge of the world. (shrink)

The Discovery of Evolution explains what the theory of evolution is all about by providing a historical narrative of discovery. Some of the major puzzles that confront anyone studying living things are discussed and it details how these were solved from an evolutionary perspective. Beginning with the emergence of the early naturalists in the seventeenth century, the scientific discoveries that led up to and then flowed from Darwin and Wallace's theory of evolution by natural selection are then discussed, and finally (...) the modern evolutionary studies at the close of the twentieth century are detailed. This new edition of The Discovery of Evolution is fully updated and contains a new chapter on the evolutionary studies of the twentieth century. By approaching the topic of evolution in this way, it is made accessible to the non-specialist and no previous study of biology is required in order to read and understand this book. (shrink)

This paper focuses on the nonlinear self-interaction of gravitational waves and explores its impact on the spectrum of the resulting gravitational wave. While many authors primarily investigate the nonlinear effects within the framework of "gravitational memory," we take a different approach by conducting a comprehensive analysis of harmonic generation. Theoretical analysis indicates that higher harmonics do not possess suitable conditions for energy accumulation. However, our study presents intriguing evidence supporting the concept of "nonlinear gravitational memory": the conversion and accumulation of (...) gravitational wave energy into a persistent metric deformation in the background space (specifically referred here to as zero harmonics). In simpler terms, a wave leaves a lasting imprint on the background space, even after the gravitational pulse subsides. Furthermore, our study estimates the significance of this effect and demonstrates that it should not be disregarded. (shrink)

Darwinian evolutionary theory has two key terms, variations and biological selection, which finally lead to survival of the fittest variant. With the rise of molecular genetics, variations were explained as results of error replications out of the genetic master templates. For more than half a century, it has been accepted that new genetic information is mostly derived from random error-based events. But the error replication narrative has problems explaining the sudden emergence of new species, new phenotypic traits, and genome innovations (...) as a sudden single event. Meanwhile, it is recognized that errors cannot explain the evolution of genetic information, genetic novelty, and complexity. Now, empirical evidence establishes the crucial role of non-random genetic content editors, such as viruses, diversity generating retroelements, and other RNA networks, to produce new genetic information, complex regulatory control, inheritance vectors, genetic identity, immunity, new sequence space, evolution of complex organisms, and evolutionary transitions.

The Red Queen hypothesis, or the ability organisms have to control and regulate the available trophic energy, is a recently proposed parameter for measuring fitness. Firstly, this hypothesis is analysed in terms of its heuristic power. Secondly, the claimed causal dependence between this parameter and a, still controversial, law of constant extinction is judged to be unjustified, however reasonable such a claim appears to be. Finally, the ubiquity of competition in nature which is seemingly required by the Red Queen and (...) supposedly realized at the expense of a mutualistic alternative, is deemed to be a questionable assumption.

My aim in this paper is to demonstrate that a very simple learning rule based on imitation can help to sustain altruism as a culturally transmitted pattern or behaviour among agents playing a standard prisoner’s dilemma game. The point of this demonstration is not to prove that imitation is single-handedly responsible for existing levels of altruism (a thesis that is false), nor is the point to show that imitation is an important factor in explanations for the evolution of altruism (a (...) thesis already prominent in the existing literature). The point is to show that imitation contributes to the evolution of altruism in a particular way that is not always fairly represented by evolutionary game theory models. Specifically, the paper uses a simple model to illustrate that cultural transmission includes mechanisms that do not transmit phenotype vertically (i.e. from parent to related offspring) and that these mechanisms can promote altruism in the absence of any direct biological propensity favouring such behaviour. This is a noteworthy result because it shows that evolutionary models can be built to explicitly reflect the contribution of non-vertical transmission in our explanations for the evolution of altruism among humans and other social species.

Cooption and modularity are informative concepts in evolutionary developmental biology. Genes function within complex networks that act as modules in development. These modules can then be coopted in various functional and evolutionary contexts. Hormonal signaling, the main focus of this review, has a modular character. By regulating the activities of genes, proteins and other cellular molecules, a hormonal signal can have major effects on physiological and ontogenetic processes within and across tissues over a wide spatial and temporal scale. Because of (...) this property, we argue that hormones are frequently involved in the coordination of life history transitions (LHTs) and their evolution (LHE). Finally, we promote the usefulness of a comparative, non-model system approach towards understanding how hormones function and guide development and evolution, highlighting thyroid hormone function in echinoids as an example.

Orthodoxy has it that language evolution requires Gricean communicative intentions and therefore an understanding of nested metarepresentations. The problem with this orthodoxy is that it is hard to see how non-linguistic creatures could have such a sophisticated understanding of mentality. Some philosophers like Bar-On (The Journal of Philosophy 110 (6): 293-330, 2013a; Mind and Language 28 (3): 342-375, 2013b) have attempted to develop a non-Gricean account of language acquisition building on the information-rich and subtle communicative powers of expressive behaviours. This (...) paper argues that this approach shares a number of instructive similarities with the literature on the cognitive conception of language. It shows how expressive accounts (and others) can learn from insights in that tradition and identifies a problem with the role of intentional actions in expressive accounts that can be solved by understanding expressive behaviours more as cognitive rather than communicative tools.

The argument that heritable epigenetic change plays a distinct role in evolution would be strengthened through recognition that it is what bootstrapped the origin and early evolution of life, and that, like behavioral and symbolic change, it is non-Darwinian. The mathematics of natural selection, a population-level process, is limited to replication with negligible individual-level change that uses a self-assembly code.

In his anthology of socio-political essays, Evolution and Human Life, Oka Asajirō, early twentieth century Japan’s foremost advocate of evolutionism, developed a biological vision of the nation-state as super-organism that reflected the concerns and aims of German-inspired Meiji statism and anticipated aspects of radical ultra-nationalism. Drawing on non-Darwinian doctrines, Oka attempted to realize such a fused or organic state by enhancing social instincts that would bind the minzoku and state into a single living entity. Though mobilization during the Russo-Japanese War (...) seemed to evince this super-organism, the increasingly contentious and complex society that emerged in the war’s aftermath caused Oka to turn first to Lamarckism and eventually to orthogenesis in the hopes of preserving the instincts needed for a viable nation-state. It is especially in the state interventionist measures that Oka finally came to endorse in order to forestall orthogenetically-driven degeneration that the technocratic proclivities of his statist orientation become most apparent. The article concludes by suggesting that Oka’s emphasis on degeneration, autarkic expansion, and, most especially, totalitarian submersion of individuals into the statist collectivity indicates a complex relationship between his evolutionism and fascist ideology, what recent scholarship has dubbed radical Shinto ultra-nationalism.

Mutualistic theory explains convincingly the prevalence of fairness norms in small societies of foragers and in large contemporary democratic societies. However, it cannot explain the U-shaped curve of egalitarianism in human history. A theory based on bargaining power is able to provide a more general account and to explain mutualism as a special case. According to this approach, social norms may be more variable and malleable than Baumard et al. suggest.

Gradual degradation seems inevitable for non‐recombining sex chromosomes. This has been supported by the observation of degenerated non‐recombining sex chromosomes in a variety of species. The human Y chromosome has also degenerated significantly during its evolution, and theories have been advanced that the Y chromosome could disappear within the next ∼5 million years, if the degeneration rate it has experienced continues. However, recent studies suggest that this is unlikely. Conservative evolutionary forces such as strong purifying selection and intrachromosomal repair through (...) gene conversion balance the degeneration tendency of the Y chromosome and maintain its integrity after an initial period of faster degeneration. We discuss the evidence both for and against the extinction of the Y chromosome. We also discuss potential insights gained on the evolution of sex‐determining chromosomes by studying simpler sex‐determining chromosomal regions of unicellular and multicellular microorganisms.

We propose a framework for analyzing the development, operation and failure to survive of all things, living, non-living or organized groupings. This framework is a sequence of developments that improve survival capability. Framework processes range from origination of any entity/system, to the development of increased survival capability and development of life-forms and organizations that use intelligence. This work deals with a series of developmental changes that arise from the uncovering of emergent properties. The framework is intended to be general, but (...) we see a potential to apply it to scientific topics such as the exploration of the origin of life or the search for life beyond Earth, and to understand some biological issues in evolution and symbiosis, and also to apply to social systems that do not seem to be operating well, to determine their problems and correct them.

A new theory about the origins of consciousness that finds learning to be the driving force in the evolutionary transition to basic consciousness. What marked the evolutionary transition from organisms that lacked consciousness to those with consciousness—to minimal subjective experiencing, or, as Aristotle described it, “the sensitive soul”? In this book, Simona Ginsburg and Eva Jablonka propose a new theory about the origin of consciousness that finds learning to be the driving force in the transition to basic consciousness. Using a (...) methodology similar to that used by scientists when they identified the transition from non-life to life, Ginsburg and Jablonka suggest a set of criteria, identify a marker for the transition to minimal consciousness, and explore the far-reaching biological, psychological, and philosophical implications. After presenting the historical, neurobiological, and philosophical foundations of their analysis, Ginsburg and Jablonka propose that the evolutionary marker of basic or minimal consciousness is a complex form of associative learning, which they term unlimited associative learning (UAL). UAL enables an organism to ascribe motivational value to a novel, compound, non-reflex-inducing stimulus or action, and use it as the basis for future learning. Associative learning, Ginsburg and Jablonka argue, drove the Cambrian explosion and its massive diversification of organisms. Finally, Ginsburg and Jablonka propose symbolic language as a similar type of marker for the evolutionary transition to human rationality—to Aristotle's “rational soul.”. (shrink)

Written for non-experts, this volume introduces the mechanisms that underlie reticulate evolution. Chapters are either accompanied with glossaries that explain new terminology or timelines that position pioneering scholars and their major discoveries in their historical contexts. The contributing authors outline the history and original context of discovery of symbiosis, symbiogenesis, lateral gene transfer, hybridization or divergence with gene flow, and infectious heredity. By applying key insights from the areas of molecular (phylo)genetics, microbiology, virology, ecology, systematics, immunology, epidemiology and computational science, (...) they demonstrate how reticulate evolution impacts successful survival, fitness and speciation. Reticulate evolution brings forth a challenge to the standard Neo-Darwinian framework, which defines life as the outcome of bifurcation and ramification patterns brought forth by the vertical mechanism of natural selection. Reticulate evolution puts forward a pattern in the tree of life that is characterized by horizontal mergings and lineage crossings induced by symbiosis, symbiogenesis, lateral gene transfer, hybridization or divergence with gene flow, and infective heredity, making the “tree of life” look more like a “web of life.” On an epistemological level, the various means by which hereditary material can be transferred horizontally challenges our classic notions of units and levels of evolution, fitness, modes of transmission, linearity, communities, and biological individuality. The case studies presented examine topics including the origin of the eukaryotic cell and its organelles through symbiogenesis; the origin of algae through primary and secondary symbiosis and dinoflagellates through tertiary symbiosis; the superorganism and holobiont as units of evolution; how endosymbiosis induces speciation in multicellular life forms; transferrable and non-transferrable plasmids and how they symbiotically interact with their host; the means by which pro- and eukaryotic organisms transfer genes laterally (bacterial transformation, transduction and conjugation as well as transposons and other mobile genetic elements); hybridization and divergence with gene flow in sexually-reproducing individuals; current (human) microbiome and viriome studies that impact our knowledge concerning the evolution of organismal health and acquired immunity; and how symbiosis and symbiogenesis can be modelled in computational evolution.

Why do humans menstruate while most mammals do not? Here, we present our answer to this long‐debated question, arguing that (i) menstruation occurs as a mechanistic consequence of hormone‐induced differentiation of the endometrium (referred to as spontaneous decidualization, or SD); (ii) SD evolved because of maternal–fetal conflict; and (iii) SD evolved by genetic assimilation of the decidualization reaction, which is induced by the fetus in non‐menstruating species. The idea that menstruation occurs as a consequence of SD has been proposed in (...) the past, but here we present a novel hypothesis on how SD evolved. We argue that decidualization became genetically stabilized in menstruating lineages, allowing females to prepare for pregnancy without any signal from the fetus. We present three models for the evolution of SD by genetic assimilation, based on recent advances in our understanding of the mechanisms of endometrial differentiation and implantation. Testing these models will ultimately shed light on the evolutionary significance of menstruation, as well as on the etiology of human reproductive disorders like endometriosis and recurrent pregnancy loss.

Building upon a non-standard understanding of evolutionary process focusing on variation and persistence, I will argue that communities and ecosystems can evolve by natural selection as emergent individuals. Evolutionary biology has relied ever increasingly on the modeling of population dynamics. Most have taken for granted that we all agree on what is a population. Recent work has reexamined this perceived consensus. I will argue that there are good reasons to restrict the term “population” to collections of monophyletically related replicators and (...) interactors, which explains why many existing models in population biology exclude by definition many genuine evolving biological individuals such as communities and ecosystems. By studying a case of community evolution (a symbiotic termite–fungus community), we will see that it is variation that is important to evolutionary processes, not populations. Variation within a population is only one of many types of variation that can lead to evolution by natural selection. The upshot of focusing on variation is that cases of community and ecosystem adaptive change become tractable in evolutionary terms. I will show that complex emergent individuals such as communities and ecosystems cannot be fully accommodated by conventional population/reproduction models but can be accommodated by variation/persistence models.
