Indole is a key environmental cue that is used by many organisms. Based on its biochemistry, we suggest indole is used so universally, and by such different organisms, because it derives from the metabolism of tryptophan, a resource essential for many species yet rare in nature. These properties make it a valuable, environmental cue for resources almost universally important for promoting fitness. We then describe how indole is used to coordinate actions within organisms, to influence the behavior of conspecifics and (...) can even be used to change the behavior of species that belong to other kingdoms. Drawing on the evolutionary framework that has been developed for understanding animal communication, we show how this is diversely achieved by indole acting as a cue, a manipulative signal, and an honest signal, as well as how indole can be used synergistically to amplify information conveyed by other molecules. Clarifying these distinct functions of indole identifies patterns that transcend different kingdoms of organisms. (shrink)

The goal of the present study was to explain the pattern of familiar and unfamiliar relationships influencing moral judgments. In this qualitative study, relationship-based moral judgments were examined according to the constructivist theory. The studied sample included 27 individuals, including 14 women and 13 men (both young and old), living in Tehran. A purposeful sampling method was used. In order to collect data, participants were faced with moral dilemmas using semi-structured interviews. The results showed that emotional intimacy, lack of tolerance (...) for loss of loved ones and avoiding future regrets, group loyalty and common goals, and real or symbolic threats and a negative relationship were factors involved in relationship-based moral judgments. These factors, alone or together with cognitive biases, lead to unfair moral judgments, and after recognizing moral concerns related to ignoring the principle of equality, people tend to use Moral Disengagement mechanisms to reduce self-blame. -/- .

’Although the empirical and conceptual underpinnings of New Finance have been rigorously tested, its ethical underpinnings have not been explored.’These are seen to derive from the social remoteness of late twentieth century individualism, which needs to be countered by sensitivity to the social context of finance and to the developmental nature of ethical behaviour. The author is Fellow in Finance at Templeton College, Oxford.

This essay argues that shifts in patronage for the postwar behavioral and social sciences were linked intimately to both intellectual and institutional changes. This broad argument comprises two subarguments: first, that there were in fact two distinct, successive patronage systems for postwar social science—not one, as is commonly assumed; and, second, that the first postwar patronage system played a major role in enabling a series of behavioral revolutions and interdisciplinary syntheses across the social sciences, while the second postwar patronage system (...) encouraged the development of specialized concepts, techniques, and technologies within the disciplines. The essay also suggests that the widespread concern among social scientists in the 1970s and 1980s that their fields were fragmenting was at least in part an unintended consequence of the rise of the second system.

For economists, sustainability and environmental valuation are connected in two ways. At the micro level, proper environmental valuation is required if projects are to be approved and rejected consistently with sustainability requirements. This is cost benefit analysis. At the macro level, many take the view that sustainability requires that national income measurement be modified so as to account for environmental damage. Such natural resource accounting is possible only if environmental damage is valued for incorporation into the economic accounts. The paper (...) reviews the techniques that economists have developed for environmental valuation. In regard to cost benefit analysis and sustainability, it is noted that the technique on which most interest focuses, the Contingent Valuation Method, involves the extension of the domain of consumer demand analysis to include the natural environment. Contributions questioning the appropriateness of this are reviewed, and it is argued that they merit more attention from economists than they have received to date. In regard to natural resource accounting, it is argued that while there is little prospect of it achieving what its proponents claim for it, the modelling that it necessarily implies has the potential to both clarify valuation issues and play an important role in informing the policy process.

The adequacy of currently popular accounts of the genetic basis for psychological altruism, including inclusive fitness, reciprocal altruism, sociality, and group selection, is questioned. Problems exist both with the evidence cited as supporting these accounts and with the relevance of the accounts to what is being explained. Based on the empathy-altruism hypothesis, a more plausible account is proposed: generalized parental nurturance. It is suggested that four evolutionary developments combined to provide a genetic basis for psychological altruism. First is the evolution (...) in mammals of parental nurturance. Second is the evolution in humans of the ability to see others as sentient, intentional agents and, thereby, to recognize other's needs, even subtle ones. Third is the evolution in humans of tender, empathic emotions as an important component of parental nurturance. Fourth is the evolution in humans of cognitive capacities that make it possible to generalize tender, empathic feelings and, thereby, altruism beyond offspring. (shrink)

Most definitions of radical emergentism characterize it epistemologically. This leads to misunderstandings and makes it hard to assess the doctrine's metaphysical worth. This paper puts forward purely metaphysical characterizations of emergentism and property emergence. It explores the nature of the necessitation relation between base and emergent and argues that emergentism entails a Humean account of causation and related relations. Then it presents arguments against emergentism, both as a wider metaphysic and as an account of consciousness. These maintain that emergentism makes (...) implausible claims about how the world works. The paper also stresses the doctrine's contemporary relevance: most current property dualists endorse views effectively identical to classical emergentism less its historical commitment to novel emergent forces.

The essay explores how the creation and evolution of life and consciousness is a direct consequence of the evolution of the universe's rudimentary biologically-patterned processes proposed in The Biological Framework for a Mathematical Universe. The essay guides the reader through the creation and development of consciousness and its embodiment in living organisms, exploring how the rudimentary biological patterns of the environment have led to the creation and evolution of organisms as “pattern recognition engines." These organisms, under specific environmental conditions, transition (...) from solely focusing on immediate survival patterns to being liberated to explore and imagine patterns in their surroundings. Their unknowing purpose is to explore the patterns within their environment and within themselves to such extent that they discover the biological correspondence between the patterns in their physiology and all of creation. Why? So that can organize themselves and their society to biology's patterns necessary for the life, resilience and potential of themselves and their society. -/- The essay presents techniques for recognizing biological patterns in reality and supports the idea of a biological framework for a mathematical universe. It accomplishes this by employing scientific, religious, and historical references. Additionally, it argues in favor of perennial wisdom and provides evidence that numerous ancient religious cultures attempted to convey the biological patterns of the universe, as well as their connections to the patterns found within human physiology.

In recent years, a proliferation of books about empathy, cooperation and pro-social behaviours (Brooks, 2011a) has significantly influenced the discourse of the life-sciences and reversed consolidated views of nature as a place only for competition and aggression. In this article I describe the recent contribution of three disciplines – moral psychology (Jonathan Haidt), primatology (Frans de Waal) and the neuroscience of morality – to the present transformation of biology and evolution into direct sources of moral phenomena, a process here named (...) the ‘moralization of biology’. I conclude by addressing the ambivalent status of this constellation of authors, for whom today ‘morality comes naturally’: I explore both the attractiveness of their message, and the problematic epistemological assumptions of their research programmes in the light of new discoveries in developmental and molecular biology.

Artificial intelligence, the "science and engineering of intelligent machines", still has yet to create even a simple "Advice Taker" [McCarthy, 1959]. We have previously argued [Waser, 2011] that this is because researchers are focused on problem-solving or the rigorous analysis of intelligence (or arguments about consciousness) rather than the creation of a "self" that can "learn" to be intelligent. Therefore, following expert advice on the nature of self [Llinas, 2001; Hofstadter, 2007; Damasio, 2010], we embarked upon an effort to design (...) and implement a self-understanding, self-improving loop as the totality of a (seed) AI. As part of that, we decided to follow up on Richard Dawkins' [1976] speculation that "perhaps consciousness arises when the brain's simulation of the world becomes so complete that it must include a model of itself" by defining a number of axioms and following them through to their logical conclusions. The results combined with an enactive approach yielded many surprising and useful implications for further understanding consciousness, self, and "free-will" that continue to pave the way towards the creation of safe/moral autopoiesis.

Why are there so many controversies in evolutionary psychology? Using a couple of concepts from philosophy of science, this paper argues that evolutionary psychology has not reached the stage of mature, normal science, since it does not currently have a unifying research program that guides individual scientists working in the discipline. The argument goes against claims made by certain proponents and opponents of evolutionary psychology, and it is supported by discussion of several examples. The paper notes that just because evolutionary (...) psychology has not reached the stage of normal science, the discipline is nevertheless a source of many progressive theoretical developments and interesting empirical discoveries.

According to John Searle, default positions, i.e., those intelligibility and action presuppositions, are some departing points from which pre-reflective and pragmatic assumptions are made. Postulating such points helps us deal with certain perennial philosophical issues, by leaving them aside. These problems are the existence of the external world, truth and facts, “direct” perception, the meaning of words, and causality. In this article, we argue that those default positions described by Searle constitute a default humanity, and their absence would dehumanize us. (...) This is particularly relevant in a default position: cooperation, which is the basis of collective intentionality and the milestone of human civilization. (shrink)

The term “deep history” refers to historical accounts framed temporally not by the advent of a written record but by evolutionary events (Smail 2008; Shryock and Smail 2011). The presumption of deep history is that the events of today have a history that traces back beyond written history to events in the evolutionary past. For human kinship, though, even forming a history of kinship, let alone a deep history, remains problematic, given limited, relevant data (Trautman et al. 2011). With regard (...) to a deep history, one conjecture is that human kinship evolved from primate social systems in a gradual, more-or-less continuous manner (see Chapais 2008); another conjecture is that kinship, in accordance with the incest account of Claude Lévi-Strauss (1969) or the fanciful, tetradic account of Nicholas J. Allen (1986), “comes into existence with a leap” (Trautman et al. 2011: 176); and yet another, the account to be developed in this paper, is that kinship, as it is understood and lived by culture bearers today, is the consequence of a profound and qualitative evolutionary transformation going from an ancestral primate-like social system predicated on extensive face-to-face interaction to the relation-based social systems that characterize human societies (Read 2012).

This article proposes an approach to understanding life that overcomes reductionist and dualist approaches. Based on Immanuel Kant’s analysis of the cognitive prerequisites of knowing an organism, I refer to an idea of Gertrudis Van de Vijver and colleagues who described a co-constitutive relationship between the cognitive activities of the observer and the living features of the organism. Using the example of a developmental series, I show that within this active and relational process, the self-generating power and teleology of the (...) organism manifest themselves on the mental level of the observer. I posit that the Kantian mode of objectification, which refers to the sensually perceptible appearance of an organism, can be supplemented by an active mode of relational or “communicative” objectification that encompasses the life of the organism and the mind of the observer. By considering the mental processes of the observer which occur during the observation of biological phenomena, this analysis introduces a phenomenological first-person perspective on the study of life “from within”, which enables an empirical investigation of the vital properties of an organism.

The field of the philosophy of biology is flourishing in its aim to evaluate and rethink the view inherited from the previous century ---the Modern Synthesis. Different research areas and theories have come to the fore in the last decades in order to account for different biological phenomena that, in the first instance, fall beyond the explanatory scope of the Modern Synthesis. This thesis is anchored and motivated by this revolt in the philosophy of biology. -/- The central target in (...) this context is the possibility of naturalizing teleology, a classical nightmare for the history of biology itself. This requires, principally, understanding the causes of teleological explanations without assuming an unfashioned backward causation of sorts. As the riddles of teleological explanations are about their temporal dimension, I analyze different temporal scales of biological processes: evolutionary, developmental, and physiological. -/- The first one is the one defended in the context of the Modern Synthesis. As expected, one of the aims of this thesis is to evaluate the adequacy of an evolutionary account of teleological explanation. The scrutiny is negative. Evolutionary explanations in the context of the Modern Synthesis lack the necessary causal roots to naturalize teleology. Concerning the physiological scale, a long tradition pushed up by Kant and the organicist movement in the 20th century allows us to better understand how teleological explanations can be naturalized in physiological process. The key notions in this temporal scale are self-organization and the recursive, looped character of physiological process. While the physiological scale may be suitably accounted by contemporaries views, such as Autonomous Systems Theory, different central teleological phenomena remain unexplained from a purely physiological perspective. In particular, different issues concerning the (adaptive) construction of organism ---such as plasticity, robustness, variation, novelty, inheritance--- deserve an ontogenetic analysis. -/- The principal aim of this thesis is to provide a theory of teleological development that falls beyond the Modern Synthesis' framework and is prompted by different insights from the history of biology. I call it Agential Teleosemantics. It rests on two central pillars. First, that developmental processes, beyond any gene-centered stance, can be understood in informational terms; i.e. developmental processes are about the interaction of developmental resources conveying biological information. The second ingredient is agentivity, namely the idea that development is regulated by an agentive system according to the adaptiveness of the phenotypic outcomes produced. The role of agency in Agential Teleosemantic is equivalent to the role of genes in the Modern Synthesis: it is responsible for explaining the order and the adaptive complexity in the living realm. -/- The second target of this thesis regards the possibility of naturalizing intentional explanations in cognitive science. The central project involved in such an aim is known as teleosemantics. Classical teleosemantics however is etiological: it explains the teleofunctions of representational systems in terms of evolutionary processes. The different disputes in the contemporary philosophy of biology provide two insights to analyze teleosemantics in cognitive science. First, the challenges against the Modern Synthesis must be extended to the evolutionary approach of etiological teleosemantics. Second, as Agential Teleosemantics suggests an alternative source for teleofunctions ---ontogeny, I offer an attempt to integrate Agential Teleosemantics into cognitive science in order to provide an alternative teleosemantic project to understand intentional explanations in cognitive science.

Language of thought theories fall primarily into two views. The first view sees the language of thought as an innate language known as mentalese, which is hypothesized to operate at a level below conscious awareness while at the same time operating at a higher level than the neural events in the brain. The second view supposes that the language of thought is not innate. Rather, the language of thought is natural language. So, as an English speaker, my language of thought (...) would be English. -/- My goal is to defend the second view. My methodology will see the project broken down into three major areas. First I will show that human thinking requires a language of thought, after which I will highlight some problems with assuming that this language is innate and hidden. Included in this section will be a small introduction to the compatibility problem. The compatibility problem offers some obvious difficulties for mentalese theories and these will be discussed. The next stage of the project will focus on evidence that can be put forward in support of the claim that natural language is the language of thought. Our most direct source of evidence comes from introspection, and this will play a dominant role in the discussion. The final part of the thesis will involve an examination of the principle arguments that have been put forward against the idea that natural language is the language of thought. My goal will be to show that these arguments do not entail the existence of mentalese, nor do they show that natural language is not the language of thought. I will provide answers to the arguments, and will explain the phenomena they point to in terms of natural language being the language of thought. (shrink)

In this two-part article series, I aim to demonstrate that a special category of desire – a state which is sought unconditionally, as an end (sought in and of itself) – is the only ultimate value that logical observers can conceive upon consideration of sufficient conceptual depth. In the first part, I attempt to demonstrate this through appealing to logical reason. In this second part, I subsequently introduce two thought experiments that collectively allow readers to test various purported ultimate values (...) against their moral intuition that the desire defined herein is the ultimate value and, ultimately, against their inability to conceive alternate conclusions which are logically consistent.

Civilizations can be perceived as living human beings that are born, mature, age, and ultimately die and disappear, passing their legacy to the future generations. These transitions may be projected to the different stages of cognitive development of children. The Western Civilization, which embodies our current state of cultural advancement from the Classic Greek to the modern period, can be paralleled by the gradual transitions of human beings toward adulthood. From this perspective, the ancient Greek era resembles the toddler years (...) of humanity at which the first “why”-type questions are being asked. The theocratic period that followed until the Renaissance can be seen as our childhood, when people lived their lives under the tight boundaries set by religious authorities. The period spanning from the Enlightenment until almost the end of the 20th century can be considered as our teenage years when people rediscover their past, are liberated from superstition, and set the path forward based on reason by a manner at which the distinction between plausible and feasible is vague. Within this scheme, postmodernism also finds its place in our teenhood. The last few decades, from this perspective, signify our entrance to adulthood at which major questions are considered answered, or at least settled, and the only path forward perceived as feasible is the one that is followed already, a state that is bringing us closer to our intellectual aging and its inevitable death. Some signs of aging-related pathologies are already manifested in today’s technology-intensive society. By identifying our intellectual age and by appreciating our health status, we may be able to proactively delay or even avert our intellectual aging and death. (shrink)

The future of human evolution triggers many discussions, in the intersection of biological, technological, and philosophical enquiry. I will discuss the proposition that the evolution of the human species will rely increasingly in stochastic phenomena in the future, by a manner at which selection will play a minimal role only. This is the direct consequence of our cultural evolution that was intensified after the Enlightenment and combined with the scientific, technological, and medical advances of our civilization, renders the perseverance of (...) our species, as its ultimate goal. This supersedes the goals instructed by biology alone as they apply to all other species. To that end, H. sapiens will be the first and only species that through its logic-based progress, defies the rationale of natural selection as an evolutionary force and forecasts a rather unpredictable future path.

The levels of selection debate is generally taken to be a debate about how natural selection can occur at the various levels of biological organization. In this paper, we argue that questions about levels of selection should be analyzed separately from questions about levels of organization. In the deflationary proposal we defend, all that is necessary for multilevel selection is that there are cases in which particles are nested in collectives, and that both the collectives and the particles that compose (...) them each separately undergo natural selection. We argue that adopting this deflationary account helps to disentangle the levels of selection and the levels of organization, and thereby contributes to advancing the levels of selection debate.

In this essay, I first show that, from the view that God is the ultimate cause of the human ability to perform ethically laudable acts, does not follow that no continuity between biological and intentional altruism is possible. In line with recent theological research concerning the non-human world, I argue that there is a partial continuity between these two forms of altruism. I also show that, from a naturalistic viewpoint, no continuity at all seems demonstrable between the two forms of (...) altruism at stake. I therefore contribute to strengthen a more general conviction, according to which evolution in itself is more persuasive than its combination with naturalism. (shrink)

In this paper, I critically assess Mark Richard’s interesting and important development of the claim that linguistic meanings can be fruitfully analogized with biological species. I argue that linguistic meanings qua cluster of interpretative presuppositions need not and often do not display the population-level independence and reproductive isolation that is characteristic of the biological species concept. After developing these problems in some detail, I close with a discussion of their implications for the picture that Richard paints concerning the dangers of (...) conceptual engineering and the prospects for dynamic notions of semantic stability.

A leading idea of cultural evolutionary theory is that for human cultures to undergo evolutionary change, cultural transmission must generally serve as a high-fidelity copying process. In analogy to genetic inheritance, the high fidelity of human cultural transmission would act as a safeguard against the transformation and loss of cultural information, thus ensuring both the stability and longevity of cultural traditions. Cultural fidelity would also serve as the key difference-maker between human cumulative cultures and non-human non-cumulative traditions, explaining why only (...) us humans, with our uniquely high-fidelity transmission capabilities, are capable of evolving and sustaining complex traditions. But what does it mean for cultural transmission to be more or less faithful? This article has two objectives. The first is to clarify the meaning and uses of the concept of cultural fidelity and to evaluate their explanatory import. I argue that cultural evolutionists use several fidelity concepts (episodic, propensity, and generalized fidelity), concepts that I will define and clarify. The second objective is to challenge the explanatory significance of a general notion of fidelity (generalized fidelity) as being both explanatorily meaningful and operationalizable. I conclude that if fidelity is to serve as an explanation of the key differences between human cumulative cultures and non-human non-cumulative traditions, then the concept will have to be redesigned and rely on different assumptions. 1Introduction 2Generalized Fidelity 2.1The need for an explanatory concept of fidelity 2.2Three conditions for a general notion of cultural fidelity 3Episodic Fidelity 3.1Measuring episodic fidelity 3.2The relevance problem 3.3Explanatory pluralism 3.4The incommensurability of fidelity metrics 4Propensity Fidelity 5Fidelity as an Explanatory Concept 5.1Explaining cultural stability 5.2Explaining human distinctiveness 6Conclusion.

This paper analyses the connection between Nietzsche’s early employment of the genealogical method and contemporary neo-pragmatism. The paper has two goals. On the one hand, by viewing Nietzsche’s writings in the light of neo-pragmatist ideas and reconstructing his approach to justice as a pragmatic genealogy, it seeks to bring out an under-appreciated aspect of his genealogical method which illustrates how genealogy can be used to vindicate rather than to subvert, and accounts for Nietzsche’s lack of historical references. On the other (...) hand, by highlighting what Nietzsche has to offer neo-pragmatism, it seeks to contribute to neo-pragmatism’s conception of genealogy. The paper argues that Nietzsche and the neo-pragmatists share a naturalistic concern and a pragmatist strategy in responding to it. The paper then shows that Nietzsche avoids a reductive form of functionalism by introducing a temporal axis, but that this axis should be understood as a developmental model rather than as historical time. This explains Nietzsche’s failure to engage with history. The paper concludes that pragmatic genealogy can claim a genuinely Nietzschean pedigree. (shrink)

Recent years have seen a surge of interest in the question of whether humans should reproduce. Some say human life is too punishing and cruel to impose upon an innocent. Others hold that such harms do not undermine the great and possibly unique value of human life. Tracing these outlooks historically in the debate has barely begun. What might philosophers have said, or what did they say, about human life itself and its value to merit reproduction? This article looks to (...) Kant, who wrote much on whether, by reproducing, humans do wrong or right morally. It assesses two main arguments: one examining whether perfect or imperfect duties condone reproduction, the other whether Kant’s teleological or, in the opposite sense, his eschatological outlooks can salvage reproduction. These two arguments are essential for building the entire argument. This article finds that, although Kant’s arguments against reproducing are strong, some of his writing seems to support reproduction as a good. Yet, must we must assume an author, even one who strove for systematicity, must be consistent over his entire oeuvre on every issue, especially if not handled directly in a single work? The article concludes that Kant does not sufficiently, systematically support anti-natalism as more moral than pro-natalism. It is best for the current debate to grapple with the very dilemma that daunted Kant. (shrink)

Developing a definition of group selection, and applying that definition to the dispute in the social sciences between methodological holists and methodological individualists, are the two goals of this paper. The definition proposed distinguishes between changes in groups that are due to group selection and changes in groups that are artefacts of selection processes occurring at lower levels of organization. It also explains why the existence of group selection is not implied by the mere fact that fitness values of organisms (...) are sensitive to the composition of groups. And, lastly, the definition explains why group selection need not involve selection for altruism. Group selection is thereby seen as an evolutionary force which is objectively distinct from other evolutionary forces. Applying the distinction between group and individual selection to the holism/individualism dispute has the desirable result that the dispute is not decidable a priori. This way of looking at the dispute yields a conception of individualism which is untainted by atomism and a conception of holism which is unspoiled by hypostatis. (shrink)

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.

Nelson and Winter’s An Evolutionary Theory of Economic Change (1982) was the foundational work of what has become the thriving sub-discipline of evolutionary economics. In attempting to develop an alternative to neoclassical economics, the authors looked to borrow basic ideas from biology, in particular a concept of economic “natural selection.” However, the evolutionary models they construct in their seminal work are in many respects quite different from the models of evolutionary biology. There is no reproduction in any usual sense, “mutation” (...) is directed as opposed to blind, and there is no meaningful distinction between phenotype and genotype. Despite these substantial departures from the conceptions of evolutionary biology, I argue that the “evolutionary” economics of Nelson and Winter is indeed a legitimate extension of Darwinian evolutionary principles to a novel domain, and that the traditional conception of evolution by natural selection must be revised. The novel features of evolutionary economics models reflect the distinctive theoretical requirements faced by economists. I further contend that reproduction, heredity, blind variation, and the genotype/phenotype distinction are all inessential to evolutionary theory, and that their role in evolutionary biology is a domain-specific feature of biological theory.

Niche construction is the process whereby organisms, through their activities and choices, modify their own and each other’s niches. By transforming natural-selection pressures, niche construction generates feedback in evolution at various different levels. Niche-constructing species play important ecological roles by creating habitats and resources used by other species and thereby affecting the flow of energy and matter through ecosystems—a process often referred to as “ecosystem engineering.” An important emphasis of niche construction theory (NCT) is that acquired characters play an evolutionary (...) role through transforming selective environments. This is particularly relevant to human evolution, where our species has engaged in extensive environmental modification through cultural practices. Humans can construct developmental environments that feed back to affect how individuals learn and develop and the diseases to which they are exposed. Here we provide an introduction to NCT and illustrate some of its more important implications for the human sciences. (shrink)

“Selfish” gene theories have offered invaluable insight into eukaryotic genome evolution, but they can also be misleading. The “selfish mitochondrion” hypothesis, developed in the 90s explained uniparental organelle inheritance as a mechanism of conflict resolution, improving cooperation between genetically distinct compartments of the cell. But modern population genetic models provided a more general explanation for uniparental inheritance based on mutational variance redistribution, modulating the efficiency of both purifying and adaptive selection. Nevertheless, “selfish” conflict theories still dominate the literature. While these (...) hypotheses are rich in metaphor and highly intuitive, selective focus on only one type of mitochondrial mutation limits the generality of our understanding and hinders progress in mito-nuclear evolution theory. Recognizing that uniparental inheritance may have evolved – and is maintained across the eukaryotic tree of life – because of its influence on mutational variance and improved selection will only increase the generality of our evolutionary reasoning, retaining “selfish” conflict explanations as a special case of a much broader theory.

Feminist epistemology has often been understood as the study of feminine "ways of knowing." But feminist epistemology is better understood as the branch of naturalized, social epistemology that studies the various influences of norms and conceptions of gender and gendered interests and experiences on the production of knowledge. This understanding avoids dubious claims about feminine cognitive differences and enables feminist research in various disciplines to pose deep internal critiques of mainstream research.

The units or levels of selection debate concerns the question of what kind of biological systems are stable enough that part of their evolution is a result of the process of natural selection acting at their level. Traditionally, the debate has concerned at least two different, though related, questions: the question of the level at which interaction with the environment occurs, and the question of the level at which reproduction occurs. In recent years, biologists and philosophers have discussed a new (...) aspect of this debate, namely the possibility that certain multi-species consortia formed by a host and its microbiome may act as a unit of selection. This thesis, however, has not been without criticism, as it is doubtful that such consortia could meet the conditions required to achieve the degree of stability that would allow them to experience natural selection. The purpose of this paper is to systematically examine such criticisms and to defend the thesis that the holobiont/hologenome can act as a genuine level of selection both in the form of an interactor and in the form of a reproducer. To do so, it will be argued that the microbiome should be characterized in functional rather than taxonomic terms. (shrink)

The hologenome concept of evolution is a hypothesis about the evolution of animals and plants. It asserts that the evolution of animals and plants was partially triggered by their interactions with their symbiotic microbiomes. In that vein, the hologenome concept posits that the holobiont (animal host + symbionts of the microbiome) is a unit of selection. -/- The hologenome concept has been severely criticized on the basis that selection on holobionts would only be possible if there were a tight transgenerational (...) host-genotype-to-symbiont-genotype connection. As our current evidence suggests that this is not the case for most of the symbiont species that compose the microbiome of animals and plants, the opportunity for holobiont selection is very low in relation to the opportunity for selection on each of the species that compose the host microbiome. Therefore, holobiont selection will always be disrupted ‘from below’, by selection on each of the species that compose the microbiome. -/- This thesis constitutes a conceptual effort to defend philosophically the hologenome concept. I argue that the criticism according to which holobiont selection requires tight transgenerational host-genotype-to-symbiont-genotype connection is grounded on a metaphysical view of the world according to which the biological hierarchy needs to be nested, such that each new level of selection includes every entity from below. Applied to hologenomes, it entails that the hologenome is a collection of genomes, and selection of hologenomes is assumed to entail cospeciation of the host with the species that constitute its microbiome. -/- Against that interpretation, I propose the ‘stability of traits’ account, according to which hologenome evolution is the result of the action of natural selection in a non-nested hierarchical world. In that vein, hologenome evolution does not entail cospeciation, and thus it does not require tight transgenerational host-genotype-to-symbiont-genotype connection. By embracing a multilevel selection perspective, I argue that hologenome evolution results from the simultaneous action of natural selection on each of the lineages that compose the microbiome, and on the assemblage composed by the host genome plus the functional traits of its microbiome. Hologenome selection occurs when the evolution of the traits of the microbiome result from their effects on the fitness of the host, and it can take the form of multilevel selection 1, or multilevel selection 2. In both cases, hologenome selection entails the evolution of microbiome traits, as well as evolution of the host genome, rather than cospeciation of lineages. (shrink)

Explaining agency is a significant challenge for those who are interested in the sciences of the mind, and non-representationalists are no exception to this. Even though both ecological psychologists and enactivists agree that agency is to be explained by focusing on the relation between the organism and the environment, they have approached it by focusing on different aspects of the organism-environment relation. In this paper, I offer a suggestion for a radical embodied account of agency that combines ecological psychology with (...) recent trends in enactive cognitive science. According to this proposal, while enactivism focuses primarily on describing how our acquired sensorimotor schemes and habits mutually equilibrate, affecting our tendency to act upon some affordances instead of others, ecological psychology focuses on studying how perceptual information contributes to the actualization of the sensorimotor schemes and habits without mediating representations, inferences, and computations. The paper concludes by briefly exploring how this ecological-enactive theory of agency can account for how socio-cultural norms shape human agency. (shrink)

‘‘Theoretical biology’’ is a surprisingly heter- ogeneous field, partly because it encompasses ‘‘doing the- ory’’ across disciplines as diverse as molecular biology, systematics, ecology, and evolutionary biology. Moreover, it is done in a stunning variety of different ways, using anything from formal analytical models to computer sim- ulations, from graphic representations to verbal arguments. In this essay I survey a number of aspects of what it means to do theoretical biology, and how they compare with the allegedly much more restricted (...) sense of theory in the physical sciences. I also tackle a recent trend toward the presentation of all-encompassing theories in the biological sciences, from general theories of ecology to a recent attempt to provide a conceptual framework for the entire set of biological disciplines. Finally, I discuss the roles played by philosophers of science in criticizing and shap- ing biological theorizing. (shrink)

There is hardly anything more central to our universe than conservation. Many scientific fields and disciplines view the law of conservation as one of the most fundamental universal laws. The Darwinian model pivots the process of evolution on variability, reproduction, and natural selection. Conservation plays a marginal role in this model and is not really universal, as the model allows exceptions to conservation, i.e. non-conservation, to play an equally important role in evolution. This anomalous role of conservation in the Darwinian (...) model raises questions: What is the reason for this anomaly? Is conservation really universal, as we tend to believe or is it not, as the Darwinian model suggests? This contribution proposes a new model of evolution that focuses on levels of organization, rather than of species, organisms, or populations. It argues that conservation is central to evolution. Not only does this new model restores the universal status of conservation but it also makes possible to resolve some outstanding problems and controversies that continue to plague the Darwinian model. The article tries to advance the broad Darwinian project that seeks to explain the process of evolution as a product of the spontaneous processes in nature. (shrink)

It is an unfortunate fact of academic life that there is a sharp divide between science and philosophy, with scientists often being openly dismissive of philosophy, and philosophers being equally contemptuous of the naivete ́ of scientists when it comes to the philosophical underpinnings of their own discipline. In this paper I explore the possibility of reducing the distance between the two sides by introducing science students to some interesting philosophical aspects of research in evolutionary biology, using biological theories of (...) the origin of religion as an example. I show that philosophy is both a discipline in its own right as well as one that has interesting implications for the understanding and practice of science. While the goal is certainly not to turn science students into philoso- phers, the idea is that both disciplines cannot but benefit from a mutual dialogue that starts as soon as possible, in the classroom.

. The approach of experiential realism could indicate where science and faith deal with the same reality, where science questions faith assumptions, and where faith goes beyond the mandate and method of science. Although prescientific, Martin Luther's theology is the classical prototype of an experiential theology. We experience God's creative power in all of reality. We discern its regularities through observation and reason. So faith opens up all the space needed by science. However, experienced reality is highly ambiguous. It obscures (...) God's intentions. God's intentions are revealed in the proclamation of the gospel: God is unconditionally for us and with us and not against us. This proclamation is a promise, appropriated in faith, and geared to a vision of what ought to become. It is based on the interpretation of a catastrophe—the cross of Christ—as God's pivotal redemptive act in human history. It goes beyond the mandate and method of science, yet it is capable of giving the latter a sense of purpose, criteria of acceptability, and authority to act in the interests of humanity and the earth. Theology challenges science to acknowledge the necessity of a transcendent frame of reference and moral accountability. Scientific insight challenges theology to reconceptualize its assumptions on God, creation, and eschatology to integrate best science. (shrink)

The impressive variation amongst biological individuals generates many complexities in addressing the simple-sounding question what is a biological individual? A distinction between evolutionary and physiological individuals is useful in thinking about biological individuals, as is attention to the kinds of groups, such as superorganisms and species, that have sometimes been thought of as biological individuals. More fully understanding the conceptual space that biological individuals occupy also involves considering a range of other concepts, such as life, reproduction, and agency. There has (...) been a focus in some recent discussions by both philosophers and biologists on how evolutionary individuals are created and regulated, as well as continuing work on the evolution of individuality.

Both the concept of a Darwinian tree of life (TOL) and the possibility of its accurate reconstruction have been much criticized. Criticisms mostly revolve around the extensive occurrence of lateral gene transfer (LGT), instances of uptake of complete organisms to become organelles (with the associated subsequent gene transfer to the nucleus), as well as the implications of more subtle aspects of the biological species concept. Here we argue that none of these criticisms are sufficient to abandon the valuable TOL concept (...) and the biological realities it captures. Especially important is the need to conceptually distinguish between organismal trees and gene trees, which necessitates incorporating insights of widely occurring LGT into modern evolutionary theory. We demonstrate that all criticisms, while based on important new findings, do not invalidate the TOL. After considering the implications of these new insights, we find that the contours of evolution are best represented by a TOL. (shrink)

We members of settler colonial culture—the latest form of what novelist and cultural critic Daniel Quinn calls Taker culture—are constrained by myriad institutions that leave us with little choice but to engage in practices that are profoundly damaging to the planet, to others, and to ourselves. Our path to living otherwise, Andrew Frederick Smith argues, lies in the threefold struggle, which is inspired by Quinn's focus on the interweaving roots of ecological, social, and personal wellbeing. These three forms of wellbeing (...) are co-implicated. We cannot enjoy one without equally enjoying the others; they are a package deal. As such, what works for people individually and collectively works for the planet, and vice versa. Reclaiming our lives and revitalizing our human and more-than-human communities are salient acts of resistance against Taker culture. They offer means of escape from our cultural captivity and an opportunity for full-spectrum wellbeing. (shrink)

A systematic theory of naturalism, bridging metaphysics and the science of complexity and emergence.

The science of genetics is undergoing a paradigm shift. Recent discoveries, including the activity of retrotransposons, the extent of copy number variations, somatic and chromosomal mosaicism, and the nature of the epigenome as a regulator of DNA expressivity, are challenging a series of dogmas concerning the nature of the genome and the relationship between genotype and phenotype. According to three widely held dogmas, DNA is the unchanging template of heredity, is identical in all the cells and tissues of the body, (...) and is the sole agent of inheritance. Rather than being an unchanging template, DNA appears subject to a good deal of environmentally induced change. Instead of identical DNA in all the cells of the body, somatic mosaicism appears to be the normal human condition. And DNA can no longer be considered the sole agent of inheritance. We now know that the epigenome, which regulates gene expressivity, can be inherited via the germline. These developments are particularly significant for behavior genetics for at least three reasons: First, epigenetic regulation, DNA variability, and somatic mosaicism appear to be particularly prevalent in the human brain and probably are involved in much of human behavior; second, they have important implications for the validity of heritability and gene association studies, the methodologies that largely define the discipline of behavior genetics; and third, they appear to play a critical role in development during the perinatal period and, in particular, in enabling phenotypic plasticity in offspring. I examine one of the central claims to emerge from the use of heritability studies in the behavioral sciences, the principle of minimal shared maternal effects, in light of the growing awareness that the maternal perinatal environment is a critical venue for the exercise of adaptive phenotypic plasticity. This consideration has important implications for both developmental and evolutionary biology. (shrink)

A cell/molecular biologist challenges the thesis that science and religion are two ways of experiencing and interpreting the world and explores instead the possible ways that the modern biological worldview might serve as a resource for religious perspectives. Three concepts—meaning, valuation, and purpose—are argued to be central to the entire biological enterprise, and the continuation of this enterprise is regarded as a sacred religious trust.

An evolutionary perspective can be applied to the analysis of cultural phenomena to describe how inheritance mechanisms can account for the development of cultural traits in a given environment. This paper aims to describe the psychosocial functioning of the political system from this perspective, focusing on the role of politicians as cultural selectors. As they are in charge of legislation, politicians have a key role in steering the evolution of cultural norms. In particular they play a leading part in determining (...) access to traditional forms of participation, such as parties. We interviewed a panel of political experts to explore the selective mechanisms shaping the Italian political system. The results show that co-option is the main method of selecting new members for parties, with the aim of keeping power within well-established structures. The specific features of the Italian political environment explain its decreasing ability to attract young activists. (shrink)
