Evolutionary developmental biology represents a paradigm shift in the understanding of the ontogenesis and evolutionary progression of the denizens of the natural world. Given the empirical successes of the evo-devo framework, and its now widespread acceptance, a timely and important task for the philosophy of biology is to critically discern the ontological commitments of that framework and assess whether and to what extent our current metaphysical models are able to accommodate them. In this paper, I argue that one particular (...) model is a natural fit: an ontology of dispositional properties coherently and adequately captures the crucial casual-cum-explanatory role that the fundamental elements of evo-devo play within that framework.

Das letzte halbe Jahrhundert hat einen unvergleichlichen Siegeszug der Molekularbiologie erlebt, zu dem die Genomik, die molekulare Zell- und Entwicklungsbiologie, die Epigenetik sowie Erkenntnisse der Stammzellbiologie als tragende Säulen beigetragen und die Biowissenschaften insgesamt in die sogenannte postgenomische Ära geführt haben. Anstelle eines verengten Blicks in den Kern der Zelle und seiner DNA hat sich das Visier von Biologen auf eine sich dynamisch verändernde Zellumgebung hin geöffnet. Wechselwirkungen zwischen molekularen, zellulären, organismischen bis hin zu ökologischen Hierarchieebenen, stets aufwärts und abwärts (...) interagierend (bottom-up und top-down), bestimmen das Bild postgenomischer Naturbetrachtung. Dieses erweiterte Gesichtsfeld führte einerseits weg von einem strikten Gen-gesteuerten Determinismus hin zu Systemdenken und zur Systembiologie. Zum anderen rückten auf diesem Weg wieder Lücken in der klassischen neodarwinistischen Lehre in den Fokus, die nach einer erweiterten Synthese der Standardlehre der Evolution rufen. So hat das neue Forschungsfeld Evo-Devo (Akronym für Evolutionary Developmental Biology) erstmals molekulare Mechanismen für die sprunghafte Entstehung von Merkmalen aufgezeigt, die die Grundlage für die Entstehung neuer Baupläne (Makroevolution) bildeten.

In identifying intrinsic molecular chance and extrinsic adaptive pressures as the only causally relevant factors in the process of evolution, the theoretical perspective of the Modern Synthesis had a major impact on the perceived tenability of an ontology of dispositional properties. However, since the late 1970s, an increasing number of evolutionary biologists have challenged the descriptive and explanatory adequacy of this “chance alone, extrinsic only” understanding of evolutionary change. Because morphological studies of homology, convergence, and teratology have revealed a space (...) of possible forms and phylogenetic trajectories that is considerably more restricted than expected, evo-devo has focused on the causal contribution of intrinsic developmental processes to the course of evolution. Evo-devo’s investigation into the developmental structure of the modality of morphology – including both the possibility and impossibility of organismal form – has led to the utilisation of a number of dispositional concepts that emphasise the tendency of the evolutionary process to change along certain routes. In this sense, and in contrast to the perspective of the Modern Synthesis, evo-devo can be described as a “science of dispositions.” This chapter discusses the recent philosophical literature on dispositional properties in evo-devo, exploring debates about both the metaphysical and epistemological aspects of the central dispositional concepts utilised in contemporary evo-devo and addressing the epistemological question of how dispositional properties challenge existing explanatory models in evolutionary biology.

The Extended Evolutionary Synthesis (EES) debate is gaining ground in contemporary evolutionary biology. In parallel, a number of philosophical standpoints have emerged in an attempt to clarify what exactly is represented by the EES. For Massimo Pigliucci, we are in the wake of the newest instantiation of a persisting Kuhnian paradigm; in contrast, Telmo Pievani has contended that the transition to an EES could be best represented as a progressive reformation of a prior Lakatosian scientific research program, with the extension (...) of its Neo-Darwinian core and the addition of a brand-new protective belt of assumptions and auxiliary hypotheses. Here, we argue that those philosophical vantage points are not the only ways to interpret what current proposals to ‘extend’ the Modern Synthesis-derived ‘standard evolutionary theory’ (SET) entail in terms of theoretical change in evolutionary biology. We specifically propose the image of the emergent EES as a vast network of models and interweaved representations that, instantiated in diverse practices, are connected and related in multiple ways. Under that assumption, the EES could be articulated around a paraconsistent network of evolutionary theories (including some elements of the SET), as well as models, practices and representation systems of contemporary evolutionary biology, with edges and nodes that change their position and centrality as a consequence of the co-construction and stabilization of facts and historical discussions revolving around the epistemic goals of this area of the life sciences. We then critically examine the purported structure of the EES—published by Laland and collaborators in 2015—in light of our own network-based proposal. Finally, we consider which epistemic units of Evo-Devo are present or still missing from the EES, in preparation for further analyses of the topic of explanatory integration in this conceptual framework.

Usually evolutionary economists equate evolutionary theory with modern Darwinism. However the rise of evolutionary developmental biology (Evo-Devo) puts into question the monopoly of Darwinism in evolutionary biology. The major divergences between the two paradigms in evolutionary biology are drawn in the analysis of three trade-offs: population vs. typological thinking, creative role of natural selection vs. internal (inherent) change, and microevolution vs. macroevolution. It is argued here that the Evo-Devo breakthrough helps to better understand the limits to Darwinism in (...) the social realm and design the contours of an alternative paradigm in evolutionary economics privileging structural macroevolution and what Schumpeter called “change from within”.

The study of organisms within the range of their existence from fertilization to birth is referred to as embryology. The process of progressive change during that period is called development. That development does not stop at birth but continues on throughout the entire life-span of the organism as the process of growth and decay — catabolism, anabolism, and metabolism. The study of this entire range of life has recently become known as developmental biology. The belief that the development from an (...) initial stage of a fertilized egg or zygote to a fully formed adult represents, in compressed time, the whole process of evolution that occurred over millions of years, has recently been named evo-devo, or evolutionary development. The more science advances, the more it studies Nature in its intimate details, the more it comes to realize the existence of a pervasive reason, an inherent natural intelligence that is working in even the most insignificant portions of the universe. Francis Bacon (1561–1626) said, “A little philosophy (science) inclineth man's mind to atheism, but depth in philosophy (science) bringeth men's minds about to religion.” This point is especially true today. It is not from ignorance that men come to have faith in God, but from a maturity of reason and experience. Vedanta philosophy teaches that there is a conscious intelligence that underlies all experienced existence. Being self-evident, this should hardly have to be argued. Yet modern science has failed to integrate this truth into its materialist/naturalistic paradigm. Correcting this deficiency will be the challenge of 21st century science, and the highest reward for humanity. (shrink)

Simona Ginsburg & Eva Jablonka (G&J), in _The Evolution of the Sensitive Soul (2019)_, explore the nature and status of the mind and subjective experiences from an evolutionary perspective. They raise a fundamental question about ‘the origin of animal consciousness during evolution’ (pg.1). The book begins by tracing the roots of consciousness studies from the Aristotelian perspective on the sensitive soul, referring to the dynamics of the living organization, percepts, and feelings. They use “subjective experiencing” to refer to both sentience (...) and consciousness. They argue that to have an evolutionary account of subjective experiences, we need to develop an understanding of minimal consciousness or a marker like unlimited associative learning (UAL) indicating subjective experiences. In the book, the origin of life is marked by the evolution of goal-directed systems where the system can manifest unlimited heredity. They state that all the questions about the origin of minimal consciousness deal with ‘the emergence of new types of goal-directed systems’ (p.1). (shrink)

The aim of this paper lies in characterizing the explanations and models used in the field of evolutionary developmental biology throughout its history. While manipulative experiments in controlled conditions have been useful to set the bases of the discipline and are still routinely performed, this approach supposes a tension between the reliability and the representativity of the conclusions. Given the recent changes in the understanding of evolutionary phenomena, different authors currently emphasize the need of avoiding excessive simplifications in experimental approaches, (...) incorporating the complexity of the analyzed systems as a relevant trait in the study of biological diversity. On the other hand, the fragile and contingent nature of evolutionary processes and the impossibility of intervening some of these phenomena underscore the importance of non-manipulative models that allow the elucidation of how-possibly mechanisms. We argue that a pluralism characterized by the integration of different kinds of explanations, models and metaphors used in evo-devo allows to exploit their respective advantages, favours interdisciplinarity and can contribute to form a representative description of evolutionary processes without relinquishing the local and detailed study of actual mechanisms.

In this condensed survey, I look to recent perspectives on evolution suggesting that cultural change likely alters the genome. Since theories of development are nested within assumptions about evolution (evo-devo), I next review some oft-cited developmental theories and other psychological theories of the 20th century to see if any match the emerging perspectives in evolutionary theory. I seek theories based neither in nature (genetics) nor nurture (the environment) but in the creative play of human communication responding to necessity. This (...) survey finally looks to more recent work to do with the appearance of independent self-consciousness in the individual following empathic group awareness. The result of such self-created group awareness and symbolic communication is seen to be cultural consciousness, unique to humanity, from which individual consciousness and personhood derive. I conclude by noting the general implications for these approaches in our schools, politics, and in ultimate ontological questions. (shrink)

This chapter introduces the main research schools and paradigms along which the field of evolutionary biology has been developing. Evolutionary thinking was originally founded upon the Neo-Darwinian paradigm that combines the teachings of traditional Darwinism with those of the Modern Synthesis. The Neo-Darwinian paradigm has since further diversified into the Micro-, Meso-, and Macroevolutionary schools, and it has also started to integrate the school of Ecology. Together, these schools establish the paradigm called Ecological Evolutionary Developmental Biology (Eco-Evo-Devo). A final (...) school studies Reticulate Evolution as it occurs by means of symbiosis, symbiogenesis, lateral gene transfer, infective heredity, and hybridization. This chapter reviews the major tenets and points of differentiation that exist between these distinct evolution schools. The chapter ends by looking into how evolution can be defined and how distinct units, levels, and mechanisms underlie theorizing on evolutionary hierarchies and evolutionary causation. The following chapter examines how the different evolution schools are implemented into the symbolic sciences. (shrink)

Though the realm of biology has long been under the philosophical rule of the mechanistic magisterium, recent years have seen a surprisingly steady rise in the usurping prowess of process ontology. According to its proponents, theoretical advances in the contemporary science of evo-devo have afforded that ontology a particularly powerful claim to the throne: in that increasingly empirically confirmed discipline, emergently autonomous, higher-order entities are the reigning explanantia. If we are to accept the election of evo-devo as our (...) best conceptualisation of the biological realm with metaphysical rigour, must we depose our mechanistic ontology for failing to properly “carve at the joints” of organisms? In this paper, I challenge the legitimacy of that claim: not only can the theoretical benefits offered by a process ontology be had without it, they cannot be sufficiently grounded without the metaphysical underpinning of the very mechanisms which processes purport to replace. The biological realm, I argue, remains one best understood as under the governance of mechanistic principles. (shrink)

The Aristotelian axiom that function follows form was beautifully instantiated in molecular biology by the discovery of DNA’s structure that immediately suggested how DNA might work as depository and vehicle for genetic information. However, later on molecular biology became infatuated with the gene that became the center of the universe. This gene-centered viewpoint is an obstacle for the emerging field of evo-devo aiming at finding the causal connections between evolution and biological development. Here it is argued that molecular biology (...) must reject the narrow-minded causality associated with the gene-centered view and so it must recover to the spirit of Aristotelian natural history and its four types of causation in order to foster the evo-devo field of research.

Ever since Darwin a great deal of the conceptual history of biology may be read as a struggle between two philosophical positions: reductionism and holism. On the one hand, we have the reductionist claim that evolution has to be understood in terms of changes at the fundamental causal level of the gene. As Richard Dawkins famously put it, organisms are just ‘lumbering robots’ in the service of their genetic masters. On the other hand, there is a long holistic tradition that (...) focuses on the complexity of developmental systems, on the non-linearity of gene– environment interactions, and on multi-level selective processes to argue that the full story of biology is a bit more complicated than that. Reductionism can marshal on its behalf the spectacular successes of genetics and molecular biology throughout the 20th and 21st centuries. Holism has built on the development of entirely new disciplines and conceptual frameworks over the past few decades, including evo-devo and phenotypic plasticity. Yet, a number of biologists are still actively looking for a way out of the reductionism–holism counterposition, often mentioning the word ‘emergence’ as a way to deal with the conundrum. This paper briefly examines the philosophical history of the concept of emergence, distinguishes between epistemic and ontological accounts of it, and comments on conceptions of emergence that can actually be useful for practising evolutionary biologists.

Never was dogmatic reductionism helpful in conceiving the phenomenon of life. The post-genomic era has made it clear that genes alone cannot explain the functioning of whole organisms. Already each cell represents a unique, non-recurring individual. Recent progress in developmental biology has conveyed new perspectives both on the makings of individual organisms (ontogeny), as on evolutionary change (Evo-Devo). The genome (the entirety of all genes) of an animal remains constant from fertilization onwards in each cell. The realization of genes (...) requires molecular environments, in particular pertinent to the cytoplasm of the unfertilized egg. Individuality of an organism therefore is not only determined by its genome, but is shaped through developmental processes (it needs time!). Organisms can only exist through mutual interplays with their respective (molecular and cellular) environments at all levels of organization. Thus, life can be conceived of as endless networks of communication, e.g. as a mutual continuum, connecting all individuals, all species and all generations within their given environments. Evolutionarily, nature does not select fitting genes, but rather viable traits. The presented concepts render it unlikely that it was genes that founded our living world, but rather that distinct environments shaped “genes” (of whatever chemical nature) which proved to be “life-suitable”.

Evolutionary developmental biology (Evo-Devo) is a new and rapidly developing field of biology which focuses on questions in the intersection of evolution and development and has been seen by many as a potential synthesis of these two fields. This synthesis is the topic of the books reviewed here. Integrating Evolution and Development (edited by Roger Sansom and Robert Brandon), is a collection of papers on conceptual issues in Evo-Devo, while From Embryology to Evo-Devo (edited by Manfred Laubichler (...) and Jane Maienschein) is a history of the problem of the relations between ontogeny and phylogeny.

Commentary on research on butterflies' eyespots as a model in evolutionary developmental biology.

Evolutionary theory is undergoing an intense period of discussion and reevaluation. This, contrary to the misleading claims of creationists and other pseudoscientists, is no harbinger of a crisis but rather the opposite: the field is expanding dramatically in terms of both empirical discoveries and new ideas. In this essay I briefly trace the conceptual history of evolutionary theory from Darwinism to neo-Darwinism, and from the Modern Synthesis to what I refer to as the Extended Synthesis, a more inclusive conceptual framework (...) containing among others evo–devo, an expanded theory of heredity, elements of complexity theory, ideas about evolvability, and a reevaluation of levels of selection. I argue that evolutionary biology has never seen a paradigm shift, in the philosophical sense of the term, except when it moved from natural theology to empirical science in the middle of the 19th century. The Extended Synthesis, accordingly, is an expansion of the Modern Synthesis of the 1930s and 1940s, and one that—like its predecessor—will probably take decades to complete. (shrink)

Applied Evolutionary Epistemology is a scientific-philosophical theory that defines evolution as the set of phenomena whereby units evolve at levels of ontological hierarchies by mechanisms and processes. This theory also provides a methodology to study evolution, namely, studying evolution involves identifying the units that evolve, the levels at which they evolve, and the mechanisms and processes whereby they evolve. Identifying units and levels of evolution in turn requires the development of ontological hierarchy theories, and examining mechanisms and processes necessitates theorizing (...) about causality. Together, hierarchy and causality theories explain how biorealities form and diversify with time. This paper analyzes how Applied EE redefines both hierarchy and causality theories in the light of the recent explosion of network approaches to causal reasoning associated with studies on reticulate and macroevolution. Causality theories have often been framed from within a rigid, ladder-like hierarchy theory where the rungs of the ladder represent the different levels, and the elements on the rungs represent the evolving units. Causality then is either defined reductionistically as an upward movement along the strands of a singular hierarchy, or holistically as a downward movement along that same hierarchy. Upward causation theories thereby analyze causal processes in time, i.e. over the course of natural history or phylogenetically, as Darwin and the founders of the Modern Synthesis intended. Downward causation theories analyze causal processes in space, ontogenetically or ecologically, as the current eco-evo-devo schools are evidencing. This work demonstrates how macroevolution and reticulate evolution theories add to the complexity by examining reticulate causal processes in space–time, and the interactional hierarchies that such studies bring forth introduce a new form of causation that is here called reticulate causation. Reticulate causation occurs between units and levels belonging to different as well as to the same ontological hierarchies. This article concludes that beyond recognizing the existence of multiple units, levels, and mechanisms or processes of evolution, also the existence of multiple kinds of evolutionary causation as well as the existence of multiple evolutionary hierarchies needs to be acknowledged. This furthermore implies that evolution is a pluralistic process divisible into different kinds. (shrink)

According to neo-Aristotelian ethical naturalism, moral goodness is an instance of natural goodness, a kind of normativity supposedly already present in nature in the biological realm of non-human living things. Proponents of this view appeal to Michael Thompson’s conception of a life-form--the form of a living organism--to give an account of natural goodness. However, although neo-Aristotelians call themselves naturalists, they hardly ever consult the science of biology to defend their commitments regarding biological organisms. This has led many critics to argue (...) that the neo-Aristotelian account of natural normativity is out of touch with the findings of modern evolutionary biology. One line of response to this objection, presented by John Hacker-Wright and Micah Lott, claims that the neo-Aristotelian concept of a living organism has to be presupposed in evolutionary biology as long as organisms are the subjects of evolutionary explanation. In this paper, I examine this response by tracing the concept of organism in modern evolutionary biology. I first argue that the Modern Synthesis theory of evolution, which understands evolution as change in gene frequencies within a population, does not presuppose the relevant concept of organism. I then explore an alternative view of evolution that has emerged in the past twenty years from advances in evolutionary developmental biology. I argue that this so called ‘evo-devo’ approach makes room for an explanatory concept of organism that can be reconciled with the neo-Aristotelian view. Moreover, I argue that although the explanatory role of the concept of organism in evolutionary biology is still contentious, the well-established role of this concept in developmental biology can be used to defend the biological commitments of neo-Aristotelian naturalism.

Mayr’s proximate–ultimate distinction has received renewed interest in recent years. Here we discuss its role in arguments about the relevance of developmental to evolutionary biology. We show that two recent critiques of the proximate–ultimate distinction fail to explain why developmental processes in particular should be of interest to evolutionary biologists. We trace these failures to a common problem: both critiques take the proximate–ultimate distinction to neglect specific causal interactions in nature. We argue that this is implausible, and that the distinction (...) should instead be understood in the context of explanatory abstractions in complete causal models of evolutionary change. Once the debate is reframed in this way, the proximate–ultimate distinction’s role in arguments against the theoretical significance of evo-devo is seen to rely on a generally implicit premise: that the variation produced by development is abundant, small and undirected. We show that a “lean version” of the proximate–ultimate distinction can be maintained even when this isotropy assumption does not hold. Finally, we connect these considerations to biological practice. We show that the investigation of developmental constraints in evolutionary transitions has long relied on a methodology which foregrounds the explanatory role of developmental processes. It is, however, entirely compatible with the lean version of the proximate–ultimate distinction. (shrink)

In a now classic paper published in 1991, Alberch introduced the concept of genotype–phenotype (G!P) mapping to provide a framework for a more sophisticated discussion of the integration between genetics and developmental biology that was then available. The advent of evo-devo first and of the genomic era later would seem to have superseded talk of transitions in phenotypic space and the like, central to Alberch’s approach. On the contrary, this paper shows that recent empirical and theoretical advances have only (...) sharpened the need for a different conceptual treat- ment of how phenotypes are produced. Old-fashioned metaphors like genetic blueprint and genetic programme are not only woefully inadequate but positively misleading about the nature of G!P, and are being replaced by an algorithmic approach emerging from the study of a variety of actual G!P maps. These include RNA folding, protein function and the study of evolvable soft- ware. Some generalities are emerging from these disparate fields of analysis, and I suggest that the concept of ‘developmental encoding’ (as opposed to the classical one of genetic encoding) provides a promising computational–theoretical underpinning to coherently integrate ideas on evolvability, modularity and robustness and foster a fruitful framing of the G!P mapping problem.

One important aspect of biological explanation is detailed causal modeling of particular phenomena in limited experimental background conditions. Recognising this allows a new avenue for intertheoretic reduction to be seen. Reductions in biology are possible, when one fully recognises that a sufficient condition for a reduction in biology is a molecular model of 1) only the demonstrated causal parameters of a biological model and 2) only within a replicable experimental background. These intertheoretic identifications –which are ubiquitous in biology and form (...) the basis of ruthless reductions (Bickle 2003)- are criticised as merely “local” (Sullivan 2009) or “fragmentary” (Schaffner 2006). However, in an instructive case, a biological model is preserved in molecular terms, and a complex biological phenomenon has been successfully reduced. In doing this the molecular model remains valid in a broader range of background conditions and meaningfully unites disparate biological phenomena. (shrink)

In recent years, the concept of evolvability has been gaining in prominence both within evolutionary developmental biology (evo-devo) and the broader field of evolutionary biology. Despite this, there remains considerable disagreement about what evolvability is. This article offers a solution to this problem. I argue that, in focusing too closely on the role played by evolvability as an explanandum in evo-devo, existing philosophical attempts to clarify the evolvability concept have been overly narrow. Within evolutionary biology more broadly, evolvability (...) offers a robust explanation for the evolutionary trajectories of populations. Evolvability is an abstract, robust, dispositional property of populations, which captures the joint causal influence of their internal features on the outcomes of evolution (as opposed to the causal influence of selection, which is often characterized as external). When considering the nature of the physical basis of this disposition, it becomes clear that the many existing definitions of evolvability at play within evo-devo should be understood as capturing only aspects of a much broader phenomenon. 1 Introduction2 The Problem of Evolvability3 The Theoretical Role of Evolvability in Evolutionary Biology3.1 The explanatory targets of evolutionary biology3.2 Selection-based explanations3.3 Lineage explanations3.4 Evolvability-based explanations3.5 What properties must evolvability have?4 What Evolvability Really Is4.1 Making sense of ft4.2 Making sense of x and b5 What of the Limbs?

The advent of contemporary evolutionary theory ushered in the eventual decline of Aristotelian Essentialism (Æ) – for it is widely assumed that essence does not, and cannot have any proper place in the age of evolution. This paper argues that this assumption is a mistake: if Æ can be suitably evolved, it need not face extinction. In it, I claim that if that theory’s fundamental ontology consists of dispositional properties, and if its characteristic metaphysical machinery is interpreted within the framework (...) of contemporary evolutionary developmental biology, an evolved essentialism is available. The reformulated theory of Æ offered in this paper not only fails to fall prey to the typical collection of criticisms, but is also independently both theoretically and empirically plausible. The paper contends that, properly understood, essence belongs in the age of evolution. (shrink)

A theoretical framework is provided to explore teleonomy as a problem of self-causation, distinct from upward, downward and reticulate causation. Causality theories in biology are often formulated within hierarchy theories, where causation is conceptualized as running up or down the rungs of a ladder-like hierarchy or, more recently, as moving between multiple hierarchies. Research on the genealogy of cosmologies demonstrates that in addition to hierarchy theories, causality theories also depend upon ideas of time. This paper explores the roots and impact (...) of both time and hierarchy thinking on causal reasoning in the evolutionary sciences. Within evolutionary biology, the Neodarwinian synthesis adheres to a linear notion of time associated with linear hierarchies that portray upward causation. Eco-evo-devo schools recognize the importance of downward causation and consequently receive resistance from the standard view because downward causation is sometimes understood as backward causation, considered impossible by adherents of a linear time model. In contrast, downward causation works with a spatial or presential time notion. Hybridization, lateral gene transfer, infective heredity, symbiosis and symbiogenesis require recognition of reticulate causation occurring in both space and time, or spacetime, between distinct and interacting ontological hierarchies. Teleonomy is distinct from these types of causation because it invokes the problem of self-causation. By asking how the focal level in a hierarchy can persist through time, self-causation raises philosophical concerns on the nature of duration, identity and individuality. (shrink)

This thesis focuses on the evolution of human social norm psychology. More precisely, I want to show how the emergence of our distinctive capacity to follow social norms and make social normative judgments is connected to the lineage explanation of our capacity to form shared intentions, and how such capacity is related to a diverse cluster of prototypical moral judgments. I argue that in explaining the evolution of this form of normative cognition we also require an understanding of the developmental (...) trajectory of this capacity. For this purpose, the thesis is organized as follow. In the first chapter, I make some methodological remarks and provide the general overview and plan for the dissertation. In the second chapter, I explain what my explanatory target is and why it matters. On the view I am defending, shared intentional psychology gives rise to a special form of psychology that enables us to engage in social normative thinking. These norms are represented as shared intentional states. Moral psychology, in contrast, is more diverse. For moral judgments define a quite heterogeneous class of mental states—although some moral judgments may involve the representation and execution of norms, certainly not all of them do. I show that although much of our distinctive social norm psychology can be explained within the framework of shared intentionality, moral judgments cannot be unified in the same way. In the third chapter, I provide the baseline of social-cognitive capacities that serve as starting point for my lineage explanation. I argue that hominin social cognition was for a very long period of our evolutionary history essentially a matter of low-level cognitive and motivational processes. On this picture, bottom-up affective processes regulated the social lives of early hominins without requiring any special top-down mechanism of normative thinking such as a capacity for understanding and representing social norms. In the fourth chapter, I argue that human-like social norm psychology evolved as a result of the selective pressures that gave rise to shared intentionality, especially the demands that came from collective hunting. Yet collective hunting was not the whole story of the evolution of shared intentionality, for our capacity to form shared intentional mental states emerged from the interplay between the selective pressures that led to cooperative breeding in humans as well as organized, goal-oriented, collective hunting. Thus, I propose an evo-devo account of shared intentionality and its normative dimension since I argue that explaining the evolution of this particular form of normative thinking crucially depends on information about the developmental trajectory of this capacity. Finally, in the fifth chapter, I focus on how social norms are acquired and how the way we learn them gives rise to some prototypical cluster of moral judgments. Thus, this chapter returns to some of themes and arguments of the first chapter by explaining how the distinction between moral judgments and nonmoral judgments can be culturally transmitted.

Traditional accounts of the role of learning in evolution have concentrated upon its capacity as a source of fitness to individuals. In this paper I use a case study from invasive species biology—the role of conditioned taste aversion in mitigating the impact of cane toads on the native species of Northern Australia—to highlight a role for learning beyond this—as a source of evolvability to populations. This has two benefits. First, it highlights an otherwise under-appreciated role for learning in evolution that (...) does not rely on social learning as an inheritance channel nor “special” evolutionary processes such as genetic accommodation (both of which many are skeptical about). Second, and more significantly, it makes clear important and interesting parallels between learning and exploratory behaviour in development. These parallels motivate the applicability of results from existing research into learning and learning evolution to our understanding of the evolution of evolvability more generally. (shrink)

Advances in the empirical sectors of biology are beginning to reveal evolvability as a major evolutionary process. Yet evolvability’s theoretical role is still intensely debated. Since its inception nearly thirty years ago, the evolvability research front has put a strong emphasis on the non-genetic mechanisms that influence the short-term evolvability of individuals within populations by causing phenotypic heterogeneity, such as developmental trait plasticity, phenotypic plasticity, modularity, the G-P map, robustness, and/or epigenetic variation. However, genetic evolvability mechanisms such as mutation or (...) recombination have a deeper history in evolutionary thought that is often overlooked by those in the evolvability research front, with recent evidence suggesting that species switch to genetic evolvability mechanisms when short-term evolvability strategies fail to relieve selective pressures. For this reason, a causal distinction must be made between genetic evolvability and the more recently emphasized non-genetic (or evo-devo) evolvability to allow for its maturation as a central explanatory concept. I conclude by arguing that the anachronisms of the scientific process are the main culprit behind recent divisions in biology and likely beyond. To streamline theoretical progress, we need to build a new science with new underlying philosophies like restricted pluralism. (shrink)

In the fall of 1990 I had just began my doc- toral studies at the University of Connecticut. Freshly arrived from Italy, I came to the United States to work with Carl Schlichting on something to do with phenotypic plastic- ity.

That paper, entitled Phe- notypic Plasticity and (...) the Origins of Diversity, was a (quite lengthy) forerunner of the (also quite bulky) book I am reviewing now. Like the paper, this volume has the potential to be momentous in the development of our ideas on phenotypic evolution. (shrink)

We explicate representational content by addressing how representations that ex- plain intelligent behavior might be acquired through processes of Darwinian evo- lution. We present the results of computer simulations of evolved neural network controllers and discuss the similarity of the simulations to real-world examples of neural network control of animal behavior. We argue that focusing on the simplest cases of evolved intelligent behavior, in both simulated and real organisms, reveals that evolved representations must carry information about the creature’s environ- ments (...) and further can do so only if their neural states are appropriately isomor- phic to environmental states. Further, these informational and isomorphism rela- tions are what are tracked by content attributions in folk-psychological and cognitive scientific explanations of these intelligent behaviors.

In his recent paper, C. Fuchs formulates QBism in the form of eight postulates. We criticise QBism as an anti-realist position and propose an alternative – contextual quantum realism (QCR). 1. A quantum state is not “an agent’s personal judgement” (QBism), nor is it subjective (QBism), but objective (QCR). It describes not the current experience (QBism), but a state of a physical system in context (QCR). 2. A quantum measurement is a (literally) measurement of quantum reality (QCR), rather than an (...) agent’s action upon its external world (QBism). It can only be regarded as an action in the sense in which a cognitive Wittgensteinian language game is an action (QCR). 3. The result of a quantum meas- urement is objective, though context-sensitive (QCR), rather than subjective (QBism), personal to the agent performing the action (QBism). 4. The quantum formalism is normative (QCR and QBism) and at the same time descriptive (QCR). The wave function tells us what to expect and how a quantum experiment should be conducted (i.e. plays the role of a norm), and also describes the state of a quantum system in context (QCR). 5. Unitary evolution is objective (QCR), not subjective (QBism). It does not express an agent’s degrees of belief (QBism). 6. Probability 1 is ontic (QCR), not an agent’s maximum degree of subjective certainty without ontic content (QBism). 7. In general, measurement outcomes are not predetermined (QCR and QBism), i.e. “unperformed measurements have no outcomes” (for QCR, this is an analytical judgement; for QBism this is a thesis), but they are predeter- mined in the case of probabilities 1 and 0 (QCR). In the case of probabilities 0 and 1, one can speak of performed measurements (QCR). 8. Quantum theory is a universal Wittgen- steinian rule (norm), i.e. a rule (norm) rooted in experience, reality (QCR). It can be used by any competent subject (QCR and QBism). We illustrate the difference between QCR and QBism on the example of how they treat “Wigner’s friend” thought experiment and consider their attitude to phenomenology. (shrink)

Change is the fundamental idea of evolution. Explaining the extraordinary biological change we see written in the history of genomes and fossil beds is the primary occupation of the evolutionary biologist. Yet it is a surprising fact that for the majority of evolutionary research, we have rarely studied how evolution typically unfolds in nature, in changing ecological environments, over space and time. While ecology played a major role in the eventual acceptance of the population genetic viewpoint of evolution in the (...) synthetic era (circa 1918-1956), it held a lesser role in the development of evolutionary theory until the 1980s, when we began to systematically study the evolutionary dynamics of natural populations in space and time. As a result, early evolutionary theory was initially constructed in an abstract vacuum that was unrepresentative of evolution in nature. The subtle synthesis between ecology with evolutionary biology (eco-evo synthesis) over the past 40 years has progressed our knowledge of natural selection dynamics as they are found in nature, thus revealing how natural selection varies in strength, direction, form, and, more surprisingly, level of biological organization. Natural selection can no longer be reduced to lower levels of biological organization (i.e., individuals, selfish genes) over shorter timescales but should be expanded to include adaptation at higher levels and over longer timescales. Long-term and/or emergent evolutionary phenomena, such as multilevel selection or evolvability, have thus become tenable concepts within an evolutionary biology that embraces ecology and spatiotemporal change. Evolutionary biology is currently suspended at an intermediate stage of scientific progress that calls for the organization of all the recent knowledge revealed by the eco-evo synthesis into a coherent and unified theoretical framework. This is where philosophers of biology can be of particular use, acting as a bridge between the subdisciplines of biology and inventing new theoretical strategies to organize and accommodate the recent knowledge. Philosophers have recommended transitioning away from outdated philosophies that were originally derived from physics within the philosophical zeitgeist of logical positivism (i.e., monism, reductionism, and monocausation) and toward a distinct philosophy of biology that can capture the natural complexity of multifaceted biological systems within diverse ecosystems—one that embraces the emerging philosophies of pluralism, emergence, and multicausality. Therefore, I see recent advances in ecology, evolutionary biology, and the philosophy of biology as laying the groundwork for another major biological synthesis, what I refer to as the Second Synthesis because, in many respects, it is analogous to the aims and outcomes of the first major biological synthesis (but is notably distinct from the inorganic and contrived progressive movement known as the extended evolutionary synthesis). With the general development of a distinctive philosophy of science, biology has rightfully emerged as an autonomous science. Thus, while the first synthesis legitimized biology, the Second Synthesis autonomized biology and afforded biology its own philosophy, allowing biology to finally realize its full scientific potential.

Biological evolution is a complex blend of ever changing structural stability, variability and emergence of new phe- notypes, niches, ecosystems. We wish to argue that the evo- lution of life marks the end of a physics world view of law entailed dynamics. Our considerations depend upon dis- cussing the variability of the very ”contexts of life”: the in- teractions between organisms, biological niches and ecosys- tems. These are ever changing, intrinsically indeterminate and even unprestatable: we do not know ahead of (...) time the ”niches” which constitute the boundary conditions on selec- tion. More generally, by the mathematical unprestatability of the ”phase space”, no laws of mo- tion can be formulated for evolution. We call this radical emergence, from life to life. The purpose of this paper is the integration of variation and diversity in a sound concep- tual frame and situate unpredictability at a novel theoretical level, that of the very phase space. Our argument will be carried on in close comparisons with physics and the mathematical constructions of phase spaces in that discipline. The role of symmetries as invariant preserving transformations will allow us to under- stand the nature of physical phase spaces and to stress the differences required for a sound biological theoretizing. In this frame, we discuss the novel notion of ”enablement”. Life lives in a web of enablement and radical emergence. This will restrict causal analyses to differential cases. Mutations or other causal differ- ences will allow us to stress that ”non conservation princi- ples” are at the core of evolution, in contrast to physical dynamics, largely based on conservation principles as sym- metries. Critical transitions, the main locus of symmetry changes in physics, will be discussed, and lead to ”extended criticality” as a conceptual frame for a better understanding of the living state of matter.

This chapter critically analyzes evolutionary epistemology as a theoretical framework for the study of science as a historical and cultural phenomenon. As spelled out by Campbell in the 1970s, evolutionary epistemology has an ambitious goal: it aims at understanding the complex relations between bio- logical evolution, especially the biological evolution of human cognition, and the cultural evolution of scientific knowledge. It eventually aims at forming an integrated causal theory of the evolution of science, starting with the evo- lution of human (...) cognition. In this chapter, the author considers Campbell’s project and specifies why it is still today a worthwhile project for explain- ing the evolution of science as a specific case of cultural evolution. But he also criticizes Campbell’s evolutionary epistemology for assuming that blind variation and selective retention are the processes through which science evolves. This assumption, the author argues, is at odds with much of what we know about scientific cognition and the history of science. He advocates (1) dropping the methodological constraint of looking for processes of blind variation and selective retention at the expense of other constructive processes and mechanisms of knowledge production; but (2) retaining the integrative point of evolutionary epistemology, which implies taking seriously the results of evolutionary psychology; and (3) retaining the populational framework for explaining the history of science, which means questioning why some scientific beliefs and practices eventually spread and stabilize in a scientific community. We end up with an updated research program for evolutionary epistemology, which faces new challenges. (shrink)

Apesar de ter florescido no século XII, a tradição do Graal, remonta ao século VI, com a história da “Destruição e Conquista da Bretanha”, escrita pelo clérigo Gildas, que não parece querer retratar mais do que fatos da época envolvendo líderes locais com status de Rei, lutas pelo poder, batalhas e assassinatos em família, todavia, se alguma tradição subterrânea (prática comum entre os judeus) havia, envolvendo esses personagens, sobre isso, Gildas, nada falou. -/- A memória desses homens guerreiros volta à (...) tona em meados do ano 828, em “A História dos Britânicos”, de Nennius, e mais tarde na “História dos Reis da Grã-Bretanha”, de Geoffrey of Monmouth, entre os anos de 1138 -1139. A tradição ressurge entre os anos de 1181 e 1190, com Chrétien de Troyes, que escreve “Perceval, a História do Graal”, que fica inacabada com sua morte. Poucos anos depois, entre 1191 e 1202, Robert de Boron escreve a “História do Graal ou José de Arimatéia”, onde introduz elementos cristãos, como o cálice da Última Ceia que recolheu o sangue do Cristo. No mito, José é preso, Cristo o visita e explica os mistérios do cálice. Após deixar a prisão, José viaja com seus sogros e outros seguidores para oeste, fundando uma dinastia de guardiões do Graal, de quem o rei Artur é descendente. Quase em seguida, surge “Parzival”, de Wolfram Schenbach, escrito entre os anos de 1195 – 1215, que, sem dúvida, é a obra mais robusta em simbolismos e que maior interesse desperta; o autor, por exemplo, não se refere ao Graal como “cálice sagrado”, mas o designa como “pedra”, expurgando, por assim dizer, o simbolismo cristão posto no romance por Robert de Boron e introduzindo o simbolismo judaico. -/- Agora, a questão da literatura arturiana parece estar ligada a algum tipo de tradição marginal que remonta aos primórdios do cristianismo, similarmente à queda da Judeia, já que absorve ambos os elementos. Chrétien de Troyes, que iniciou este novo ciclo da tradição, deixa a entender que escreveu sua história a pedido de Philip I, Conde de Flandres, da Casa de Alsace, isso por que o prólogo da obra (316) é dedicada a seu patrono com altos elogios, apresentando-o como o mais bravo dos homens do Império de Roma, dedicatória similar feita a uma obra anterior, encomendada por Maria de Champagne. Outro dado que chama a atenção, é a possibilidade de Chrétien ter sido um judeu convertido, hipótese fundamentada no fato de a cidade de Troyes ter sido um grande centro de comércio e ensino judaicos, mas também pela assinatura em um de seus poemas, “Philomena”, onde se refere como “Crestien li Gois” e o termo “Goy” implicaria um judeu convertido (317). -/- Logo a seguir à obra de Chrétien, Robert de Boron retoma a tradição acrescentando motivos cristãos e, tal como seu antecessor, a serviço de um nobre, Gautier de Montbéliard (318), da Casa de Montfaucon. Apesar de a obra de Robert ter se popularizado pelos elementos novos que introduziu, não é aquela que mais desperta interesse entre os estudiosos, no entanto, a adição de símbolos cristãos em uma tradição a princípio não cristã, pode referir-se a desvio de foco, mais que a qualquer outro objetivo, ideia que é reforçada quando entendemos que os autores escrevem a pedido de determinadas famílias nobres. Quase ao mesmo tempo, surge a obra capital do romance do Graal, escrita pelo alemão Wolfram Schenbach, que, não fugindo à regra, liga sua história à Casa de Anjou, na época, a família mais poderosa na Europa Ocidental e na Terra Santa, onde seus membros se revezavam como reis de Jerusalém. Um dado curioso é que Philip I, Conde de Flandres da Casa de Alsace, patrono da Chrétien de troyes era primo em primeiro grau do Rei Balduíno, de Jerusalém, da Casa de Anjou. -/- Wolfram Schenbach cita Kyot de Provence, identificado como Guiot de Provins, como sendo sua fonte (319). Historicamente, Guiot foi um autor renomado e popular em sua época, monge e porta voz dos Templários, que escreveu, desde canções de amor, a críticas à Igreja e também canções de adoração ao Templo, o que parece indicar uma origem judaica. Segundo Wolfram, kyot encontrou na cidade de Toledo (320) um antigo manuscrito escrito por Flegetanis, um judeu forçado ao batismo cristão, contendo a história “daquilo que era chamado Graal”, esse é um ponto importante quando entendemos que estamos lidando com uma tradição judaica e não cristã. Depois de ler o manuscrito, Kyot passa a investigar alguns dados nele contido, em vários centros da Europa, buscando principalmente as obras de escrita latina, encontrando finalmente, na França, nos anais da Casa de Anjou (321) ; a história de Mazadan e o registro de sua família (322). -/- O que essa informação quer nos dizer, nas entrelinhas, é que os registros familiares de Mazadan, foram reconhecidos como sendo os mesmos dos manuscritos de Flegetanis, no entanto, alguns estudiosos de “Parzival” dão como não confiável a referência ao personagem Kyot de Provence, não o identificando a Guiot de Provins (323), talvez porque Wolfram não faz qualquer referência ao poeta até o livro oito, para, abruptamente, citá-lo no livro nove, onde explica toda a história. Quero dizer que a referência feita no livro nove e não antes, como seria habitual, denota um antigo simbolismo judaico de utilizar o algarismo “nove” como expressão da verdade (324), veja, por exemplo, a fundação da Ordem do Templo por simbólicos “nove” cavaleiros, não mais, não menos. Das obras, portanto, sobre o romance do Graal, aquela que merece estudo e investigação é Parzival, se quisermos um motivo dentre tantos, a “coisa” que os outros autores chamam Graal, Wolfram não denomina “cálice”, mas “pedra”. -/- William: Lancio; pensei ter entendido quando você falou sobre o simbolismo do cálice associado ao romance do Graal. Mas agora estou confuso, quando diz que o cálice foi um motivo cristão adaptado a essa tradição e a que merece estudo e investigação é aquela em que o Graal não é simbolizado pelo cálice e sim por uma pedra. -/- Lancio: William, quando falamos ou escrevemos sobre simbolismo, o discurso ganha muitas e diferentes interpretações e todas estarão sempre em conformidade com a capacidade daqueles ou daquelas que nos ouvem ou nos leem, mas, todos aqueles que forem além da leitura ou do simples ouvir, questionarão e esses saberão mais. Quando me referi ao cálice como símbolo, associando-o à tradição do Graal, o fiz como ilustração simbólica a uma ritualística, nesse caso; o cálice é aquele que toma variadas formas, que é maleável a diversas leituras e interpretações, que é histórico e é judeu, não é fábula e por isso é também pedra. -/- William: desculpe, Lancio, eu continuo sem entender. A que cálice que também é pedra você se refere? -/- Lancio: o mesmo símbolo que sempre representou a tradição do Graal, não em Robert de Boron, mas em Wolfram Schenbach. Novamente, William, o cálice, antes de ser um símbolo cristão pela fábula de José de Arimatéia, é um símbolo judaico e quando discorri sobre esse simbolismo, era o cálice judaico ou o que se designou chamar de cálice, que Wolfram chamou de “pedra”, o símbolo em questão. -/- William: por maior esforço de memória, eu não consigo compreender a substituição de cálice por pedra dentro do mesmo simbolismo. Quando você deu o exemplo do coração como cálice, sim, é passível de entendimento, mas substituir o coração por pedra e manter o mesmo significado simbólico? -/- Lancio: a dúvida corajosa é a boa dúvida e isso em qualquer disciplina, por ser ela capaz de provocar perguntas capitais. Em poucas palavras, com o que já ouviu; você será capaz de entender o simbolismo do cálice. Primeiro devemos buscar, nas tradições judaicas, um ato ritualístico em que o cálice participe e não é difícil encontrá-lo, pois há no seio do judaísmo uma tradição em que o cálice ou vaso de ouro, como também é chamado, participa, refere-se ao sacrifício das frutas frescas, (omer), contudo, esse simbolismo em que está inscrito o cálice, nada diz à nossa investigação, é uma tradição judaica e nela se encerra, mas não podemos dizer o mesmo da sua representação nas moedas cunhadas pelos seguidores de Judas, o Galileu, quando estes tomaram Jerusalém e o Templo em 66 DC, dando início à primeira revolta contra Roma, proporcionando ao reino judeu, um breve período independência (326). Assim, torna-se ele, o cálice, símbolo daquela revolta e mais do que isso, torna-se o cálice um símbolo em si mesmo, capaz de servir à lembrança e à memória. Quando fiz referência ao simbolismo do cálice, era a esse simbolismo que me reportava e quanto à sua metamorfose em pedra, falarei agora. -/- Wolfram chama aquilo que representa o Graal, não de “cálice”, mas de “lapsit exiliis”, cuja tradução, apesar dos esforços de pesquisa e imaginação, definitivamente não está resolvida. -/- O nome “lapsit exillis” reúne assim como o nome “Lazalies”, “Mazadan” ou “Terdelaschoye”, um sentido propositadamente ambíguo, por isso há sempre dificuldade quanto a seu estudo (337), se é possível encontrar um tímido consenso sobre o significado da palavra lapsit, como sendo “pedra”, no que se refere à palavra composta, entretanto, não há consenso algum quanto ao significado, sendo muitas e corajosas, as interpretações que se tem buscado dar, inclusive com o sentido de “pedra do exílio” ou “pedra exilada”(338), que embora esteja no cesto das interpretações fantasiosas, devo dizer que não deveria, porque “pedra” é uma palavra largamente utilizada nos escritos judaicos com sentido além do literal, significando família, isso é possível devido a composição das palavras na língua hebraica, constituídas em sua maioria por duas ou mais palavras menores, assim pedra, “even”, soletrado, alef, beit, nun, é um acrônimo para av - ben, que significa “pai e filho”, representando a palavra pedra, esse conceito. -/- Esse simbolismo permeia toda a literatura judaica cristã (339). Quando, por exemplo, se diz em determinado versículo que Jacob pegou “pedras” e colocou sob sua cabeça como travesseiro e em outro versículo que Jacob ao acordar tirou a “pedra”, no singular, que tinha posto anteriormente sob sua cabeça; isso revela uma aparente discrepância, no entanto, isso significa, à luz dos intérpretes da Lei, que as “pedras”,no plural, significam os 12 filhos de Jacob, as 12 tribos de Israel que se fundiram em um só povo, uma só nação, uma só “pedra.”(340) Portanto, chamar o Graal por “lapsit exiliis” ou “pedra exilada” ou “pedra do exílio” ou ainda “pedra no exílio”, pelo simbolismo hebreu, significa o mesmo que dizer; família exilada, família do exílio ou família no exílio, termo aplicável ao povo judeu em geral e às famílias judias em particular, mas por ser o romance do Graal uma tradição relacionada a uma família específica, é a essa família que devemos buscar.

Research in ecology and evolutionary biology (evo-eco) often tries to emulate the “hard” sciences such as physics and chemistry, but to many of its practitioners feels more like the “soft” sciences of psychology and sociology. I argue that this schizophrenic attitude is the result of lack of appreciation of the full consequences of the peculiarity of the evo-eco sciences as lying in between a-historical disciplines such as physics and completely historical ones as like paleontology. Furthermore, evo-eco researchers have gotten stuck (...) on mathematically appealing but philosophi- cally simplistic concepts such as null hypotheses and p-values defined according to the frequentist approach in statistics, with the consequence of having been unable to fully embrace the complexity and subtlety of the problems with which ecologists and evolutionary biologists deal with. I review and discuss some literature in ecology, philosophy of science and psychology to show that a more critical methodological attitude can be liberating for the evo-eco scientist and can lead to a more fecund and enjoyable practice of ecology and evolutionary biology. With this aim, I briefly cover concepts such as the method of multiple hypotheses, Bayesian analysis, and strong inference. (shrink)

Neste texto pretendo analiticamente tomar o conceito foucaultiano de biopolítica no sentido de escancarar o movimento que ora inclui ora exclui certas formas de vida no contexto da pandemia da COVID-19. A questão é saber que formas de vida são levadas em consideração quando os desafios a que são confrontados gestores da ordem governamental conduzem medidas pautadas por uma lógica econômica neoliberal. Devo trabalhar metodologicamente sobre atos enunciativos dispersos proferidos em diferentes instâncias de saber. De partida, adoto o pressuposto (...) de que vozes de saber – política, estatística, biomédica --, nem sempre coincidem no modo de fazer dizer e significar o fenômeno da pandemia. O dispositivo analítico, portanto, deve alinhar os dizeres sobre a pandemia do novo coronavírus à maneira de compreendê-los. Quero mostrar a atualidade do conceito de biopolítica como operador da análise de um certo jogo de relações de poder historicamente situado no presente de uma pandemia em curso. (shrink)
