Horseshoe crabs (Limulus polyphemus) have been in decline in Long Island Sound, and recently there has been discussion of whether the state of Connecticut should stop issuing licenses for commercial harvesting. This paper argues that in spite of concerns about the living fossil concept, the fact that the horseshoe crabs are living fossils should count in favor of more stringent protection. The paper distinguishes four different views about the status of the living fossil concept: 1) eliminativism; 2) redefinition; 3) reframing; (...) and 4) conceptual pluralism. Approaches 2–4 all treat the criteria associated with living fossils as picking out distinctive features of evolutionary history. Those distinctive features of evolutionary history link up with conservation values in several ways. More generally, drawing upon relevant work in environmental philosophy, it is argued that evolutionary history is relevant to aesthetic and environmental value. Moreover, eliminativists have trouble rendering intelligible a striking pattern in the recent scientific literature. Researchers undertaking conservation-relevant work frequently highlight the living fossil status of the taxa under study. (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.

The concept of evolvability—the capacity of a population to produce and maintain evolutionarily relevant variation—has become increasingly prominent in evolutionary biology. Paleontology has a long history of investigating questions of evolvability, but paleontological thinking has tended to neglect recent discussions, because many tools used in the current evolvability literature are challenging to apply to the fossil record. The fundamental difficulty is how to disentangle whether the causes of evolutionary patterns arise from variational properties of traits or lineages rather than being (...) due to selection and ecological success. Despite these obstacles, the fossil record offers unique and growing sources of data that capture evolutionary patterns of sustained duration and significance otherwise inaccessible to evolutionary biologists. Additionally, there exist a variety of strategic possibilities for combining prominent neontological approaches to evolvability with those from paleontology. We illustrate three of these possibilities with quantitative genetics, evolutionary developmental biology, and phylogenetic models of macroevolution. In conclusion, we provide a methodological schema that focuses on the conceptualization, measurement, and testing of hypotheses to motivate and provide guidance for future empirical and theoretical studies of evolvability in the fossil record.

The article is devoted to a comprehensive analysis of the transformation of the reflection of computer technologies and network resources in the Terminator cinematic and literary universe created by the American director J. Cameron in the mid 1980s and early 2020s. In this study the authors substantiate the relevance and scientific component of the problem under study. The paper considers the degree of importance of high technologies and social networks in modern public life. The article provides a justification for the (...) fallacy of the judgment, according to which works of fiction of a fantastic orientation perform purely entertaining function and do not carry a significant semantic load. This article also provides an argument for choosing the Terminator fantastic universe as an example for research, wit an analysis of the reasons for its great popularity and high degree of significance for contemporary art. The authors of the work subject the key components of the topic under consideration to reflection, taking into account the changes that have taken place in the public consciousness over three and a half decades, takin inti account the differences in historical and political realities – from the last quarter of the 20-th century to the present, until the beginning of the third decade of the XXI century. This article provides a comparative analysis of the reasons for significant differences in the display of high technology and online resources in cinema and fiction. The work draws parallels and analogies with historical events, analyzes the use of the religious meanings used in the Terminator universe. The authors of the article analyze the moral issues that are raised by the creators of the fantastic universe of Terminator in the context of the positive and negative consequences of the intense growth of the role of high technologies and communicative Internet sites in the life of human society.

It is widely accepted that stressful conditions can facilitate evolutionary change. The mechanisms elucidated thus far accomplish this with a generic increase in heritable variation that facilitates more rapid adaptive evolution, often via plastic modifications of existing characters. Through scrutiny of different meanings of stress in biological research, and an explicit recognition that stressors must be characterized relative to their effect on capacities for maintaining functional integrity, we distinguish between: (1) previously identified stress-responsive mechanisms that facilitate evolution by maintaining an (...) adaptive fit with the environment, and (2) the co-option of stress-responsive mechanisms that are specific to stressors leading to the origin of novelties via compensation. Unlike standard accounts of gene co-option that identify component sources of evolutionary change, our model documents the cost-benefit trade-offs and thereby explains how one mechanism—an immediate response to acute stress—is transformed evolutionarily into another—routine protection from recurring stressors. We illustrate our argument with examples from cell type origination as well as processes and structures at higher levels of organization. These examples suggest a general principle of evolutionary origination based on the capacity to switch between regulatory states related to reproduction and proliferation versus survival and differentiation.

Xunzi 荀子 provided naturalistic answers to questions regarding human sociality and our characteristic “groupishness” (qun 羣). Central to his theories were so-called “social divisions and righteousness” (fenyi 分義), which can be interpreted as a uniquely human package of “cultural technology” produced via cultural evolution to suppress intragroup conflict stemming from what Xunzi calls “the mind of covetous comparison” (liangyi zhi xin 兩疑之心). For Xunzi, fenyi is the uniquely human attribute which kickstarts a salutary causal chain which facilitates prosociality and the (...) upscaling of cooperation, and ultimately results in human ecological dominance. This essay will argue that an incipient form of cultural evolution is discoverable in the Xunzi, and moreover that a solution to the problem of the origin of the “ritual and righteousness” (liyi 禮義) cultural package derives neatly from the incipient cultural evolution of the Xunzi. That is to say, while this solution is not explicitly adduced in the Xunzi, it is nonetheless consistent with Xunzian ideas and is an improvement on the much-lambasted solution Xunzi actually gives, according to which “the former kings hated … chaos, and so they established rituals and righteousness.”.

Given the pervasiveness of gene sharing in evolution and the extent of homology across the tree of life, why is everything not homologous with everything else? The continuity and overlapping genetic contributions to diverse traits across lineages seem to imply that no discrete determination of homology is possible. Although some argue that the widespread overlap in parts and processes should be acknowledged as “partial” homology, this threatens a broad base of presumed comparative morphological knowledge accepted by most biologists. Following a (...) long scientific tradition, we advocate a strategy of “theoretical articulation” that introduces further distinctions to existing concepts to produce increased contrastive resolution among the labels used to represent biological phenomena. We pursue this strategy by drawing on successful patterns of reasoning from serial homology at the level of gene sequences to generate an enriched characterization of serial homology as a hierarchical, phylogenetic concept. Specifically, we propose that the concept of serial homology should be applied primarily to repeated but developmentally individualized body parts, such as cell types, differentiated body segments, or epidermal appendages. For these characters, a phylogenetic history can be reconstructed, similar to families of paralogous genes, endowing the notion of serial homology with a hierarchical, phylogenetic interpretation. On this basis, we propose a five-fold theoretical classification that permits a more fine-grained mapping of diverse trait-types. This facilitates answering the question of why everything is not homologous with everything else, as well as how novelty is possible given that any new character possesses evolutionary precursors. We illustrate the fecundity of our account by reference to debates over insect wing serial homologs and vertebrate paired appendages. (shrink)

Throughout his life, John Tyler Bonner contributed to major transformations in the fields of developmental and evolutionary biology. He pondered the evolution of complexity and the significance of randomness in evolution, and was instrumental in the formation of evolutionary developmental biology. His contributions were vast, ranging from highly technical scientific articles to numerous books written for a broad audience. This historical vignette gathers reflections by several prominent researchers on the greatness of John Bonner and the implications of his work.

The cognitive scientist Donald Hoffman argues that we don't perceive reality: spacetime, objects, colors, sounds, tastes, and so forth, are all merely an interface that we evolved to track evolutionary fitness rather than to perceive truths about external reality. In this paper, I expound on his argument, then I extend it, primarily, by looking at key ideas in physics that are quite germane to it. Among the topics in physics that I discuss are black holes, the holographic principle, string theory, (...) duality, quantum gravity, and special relativity. I discuss these ideas from physics with an eye to their relevance for Hoffman's view. (shrink)

Many have argued that the very notion of human nature is untenable given the facts of evolution and should accordingly be discarded. This paper, by contrast, argues that the notion can be retained in a coherent and modern way. The present account expounds on the view of human nature as a collection of species-typical psychological adaptations, and outlines how it can be understood in formally modeled computational terms. The view defended is also heavily developmental and connects directly with contemporary evolutionary (...) developmental biology. Furthermore, the notion of human nature developed here allows us to abstract away from the obfuscating variability that manifests not only between individuals across ontogeny, but also cross-culturally and throughout time.

The book is an in-depth study of naturalized epistemology in its two versions - physicalist and evolutionist. At the same time, it is the sole existing detailed discussion of evolutionary epistemology (as far as Polish and foreign literature is concerned). Malinowska asks about the ontological, methodological, and epistemological foundations of the positions she discusses. She argues (referring not only to philosophical discussions but also those in the field of neuroscience or genetics) that bio-cultural constructivism (a research program pursued by cultural (...) neuroscience, among other fields) is a contemporary, interdisciplinary continuation of the evolutionary epistemology program. The book’s accessible language, clear structure and multidisciplinary nature make it an exciting read for a wide audience. (shrink)

I present a detailed ethnographic study of magic and divination of the Nuosu people in southwest China and offer a cognitive account of the surprising prevalence of these objectively ineffective practices in a society that has ample access to modern technology and mainstream Han culture. I argue that in the belief system of the Nuosu, ghosts, divination, and magical healing rituals form a closely interconnected web that gives sense and meaning to otherwise puzzling practices, and such a belief system is (...) importantly supported and reinforced by individual’s everyday experiences. Contemporary Nuosu people overwhelmingly treat these practices as instruments for achieving specific ends and often entertain considerable uncertainty regarding their efficacy, which may be overestimated for a number of reasons, including the following: (1) the intuitive plausibility of divination for ghost identification and exorcist rituals is enhanced by the belief in the existence of ghosts as a result of abductive reasoning, (2) negative instances (divinatory or healing ritual failures) are underreported, and (3) people’s misperception of the probability of uncertain events’ occurrence often prevents them from realizing that the efficacies of magical/divinatory practices do not outperform chance. I conclude with some comments on the generalizability of the psychological and social mechanisms discussed. (shrink)

This article represents comments arising from The Compatibility of Evolution and Design by Rope Kojonen (Palgrave Macmillan, 2021) concerning the role of chance and randomness in evolution (citations from this book are shown as page numbers in brackets). The various meanings of chance and randomness as used in descriptions of biological evolution are discussed and contrasted with their meanings in mathematics and metaphysics. The discussion relates to the role of contingency in evolution and to ideological and rhetorical extrapolations from biology (...) into philosophical world views. Overall it is concluded that evolution is not a chance process, except in the epistemic sense of “chance.” Theologically, this has implications for the idea that God creates through “a free evolutionary process” and may also influence our perspectives on divine action and intentionality in evolutionary history.

Human death is natural from the perspective of evolutionary biology but unnatural from the vantage point of classical Christian theology. The biblical notion that death entered the world as a result of sin seems hard to square with the view that (human) death has been an integral part of the natural order all along. I suggest an ecumenical solution to this conundrum by retrieving and elaborating the Augustinian modal distinction between strong and weak immortality. It is argued on exegetical and (...) theological grounds that the human being can best be seen as being created in a state of posse mori et posse non mori, and that—when conceptual ambiguities in their writings are dissolved—this is what theologians as diverse as the prelates of the Council of Trent, John Calvin, Louis Berkhof, and Wolfhart Pannenberg had in mind. It is also argued that this solution is compatible with contemporary evolutionary science and can be accepted by creationists of various stripes. (shrink)

In this article, I first interpret and evaluate the main argument of E. V. R. Kojonen's book, The Compatibility of Evolution and Design. I then address a challenge against this argument (as well as against design arguments in general), namely, the problem of seemingly malevolent and bad designs in nature. Evolutionary theodicists commonly deal with this problem by assuming that the evolutionary process is not fully under God's control. This solution, however, is deeply problematic from the perspective of classical theism. (...) I therefore suggest another approach to the problem, inspired by the thought of Thomas Aquinas. (shrink)

This article engages Kojonen's discussion of scientific explanation. Kojonen claims the best way to conceptualize the relationship between evolutionary explanations and explanation by design is through the proximate-ultimate distinction and the levels metaphor. However, these are not robust explanatory models but examples of how one might differentiate ambiguous explananda contained in why-questions. Disambiguating explananda is a helpful tool for determining when a situation calls for further explanation; however, on this picture, that some further explanation is needed does not, as proponents (...) of design arguments assume, specify design. The question of whether design is a good explanation at all hinges on what precisely we want explained. (shrink)

In the recent book The Compatibility of Evolution and Design, E. V. R. Kojonen argues that a biological design inference is still possible in light of mainstream evolutionary theory and that evolution and design need not be in explanatory tension. This collection of essays is the product of a symposium held in March 2022, which interacted with the claims of the book. Contributors come from diverse academic backgrounds across philosophy, science, and theology, and both critique and extend Kojonen's argument. Here, (...) each contribution is introduced along with some important connections between them and key questions which remain open. (shrink)

The effectiveness of evolutionary algorithms is one of the issues discussed in The Compatibility of Evolution and Design, where it is argued that such algorithms are only effective when stringent preconditions are met. This article considers this issue from the perspective of computer science. It explores the properties of problems that can be effectively solved by evolutionary algorithms, and the extent to which such algorithms need to be carefully adjusted. Although there are important differences between the study of evolutionary algorithms (...) in computer science and the study of biological evolution, it is argued that the experience of computer science can help to strengthen the claim that evolutionary mechanisms generally require a considerable degree of fine-tuning.

Denis Alexander, David Glass, Peter Jeavons, Meghan Page, Bethany Sollereder, and Mats Wahlberg have offered interpretations, critique, and defenses of E. V. R. Kojonen's book The Compatibility of Evolution and Design. Here, Kojonen responds to their comments on wideranging issues related to the teleology and evolution, from models of God as Creator to the meaning of randomness and design.

The first half of this article offers two possibilities of how the argument Kojonen makes might be vulnerable to other new developments in evolutionary science and psychology—potential broadsides that might threaten to sink the salvaged ship of design once again. Work on the development of life suggests that life is a simplification of surrounding environmental information, and therefore life does not generate new information. Second, the psychology of pareidolia suggests we find design as a bias of our information processing, rather (...) than observing something that exists. The second half of the article offers a critique of how the metaphors we use to describe God and the world shape our approaches to solving theological and philosophical questions (particularly theodicy). I offer some organic metaphors in place of the usual mechanistic metaphors to think about how the design argument could be reformulated. (shrink)

The scientific study of consciousness or subjective experiencing is a rapidly expanding research program engaging philosophers of mind, psychologists, cognitive scientists, neurobiologists, evolutionary biologists and biosemioticians. Here we outline an evolutionary approach that we have developed over the last two decades, focusing on the evolutionary transition from non-conscious to minimally conscious, subjectively experiencing organisms. We propose that the evolution of subjective experiencing was driven by the evolution of learning and we identify an open-ended, representational, generative and recursive form of associative (...) learning, which we call Unlimited Associative Learning (UAL), as an evolutionary transition marker of minimal consciousness. This evolutionary marker provides evidence that the evolutionary transition to consciousness has gone to completion and allows reverse-engineering from this learning capacity to the system that enables it – making possible the construction of a toy model of UAL. The model allows us to identify some of the key processes and structures that constitute minimal consciousness, points its taxonomic distribution and the ecological context in which it first emerged, highlights its function and suggests a framework for exploring developmental and evolutionary modifications of consciousness. We point to ways of experimentally testing the relationship between UAL and consciousness in human and in non-human animals and discuss the theoretical and ethical implications of our approach. The framework we offer allows the exploration of the evolutionary changes in agency, value systems, selective processes and goals that were involved in the transition to subjective experiencing from a perspective that resonates with the approaches of bio-semioticians.

Conscious Agency is a major driver of evolution. Artificial Selection (i.e. Conscious Selection by human breeders) was the foil against which Charles Darwin defined Natural Selection. In later work, he extended Artificial Selection to other species. That ability for social (e.g. sexual) selection must have evolved. Jablonka and Ginsburg identify markers of conscious agency, such as Unlimited Associative Learning (UAL), and show that it must have existed at the time of the Cambrian Explosion. To their insights, my commentary argues that (...) the harnessing of stochasticity was also involved in the evolution of the faculty of choice in organisms. (shrink)

Although Jakob von Uexküll´s Umwelt theory is not mentioned in Jablonka and Ginsburg´s Target article, von Uexküll´s theory is clearly relevant in the context of the article, with the authors´ emphasis on the origin of “subjective experiencing”. I relate some of Jablonka and Ginsburg´s main claims to an evolutionary perspective on Umwelt theory. As it turns out, the Umwelt has multiple evolutionary origins depending on our exact definition(s) of Umwelt.

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.

One of the fundamental fallacies of racism is the confusion between biological accidents such as: body, colour, environment, size, shape, and melanin with metaphysical essences like; soul, mind, and intellect. Personness for instance is an essential category that does not depend on the above accidental attributes. Since time immemorial, racism has been reinforced by deeply entrenched social structures. These structures are the offspring of both overt and covert racism. Structural racism is epitomised by ideologies that have been well disguised under (...) facades of science. These ideologies include: Eugenics, Social Darwinism, Modernisation theory and Neo-liberalism. This paper critically analyses the religious, political, psychoanalytic, historical and economic construction of structural and institutional racism that reinforces honorary whiteness in the African social milieu. The paper argues that the purpose of racism is constructing Black and Brown people as entities in dire need of White Saviourism and White Paternalism. This consequently culminates into imperialism, neo-colonialism, subjugation and exploitation. The paper further contends that racism is crystalised through mental colonialism which rides on socially constructed racial binaries, dichotomies and hierarchies such as: White (righteous) and Black (evil), North (top) and South (bottom), West (Sun-rise) and (Sun-set), Aryan and Honorary Aryan, White and Honorary White.

The goal of this programmatic paper is to highlight a close connection between the core problem in the philosophy of medicine, i.e. the concept of health, and the core problem of the philosophy of mind, i.e. the concept of consciousness. I show when we look at these phenomena together, taking the evolutionary perspective of modern state-based behavioural and life-history theory used as the teleonomic tool to Darwinize the agent- and subject-side of organisms, we will be in a better position to (...) make sense of them both as natural phenomena.

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)

Introduction. Modelling is an important step in the analysis of a complex system functioning. It allows to define how the elements of the system are joined together, how they function; and to plan the directions of their development in the future. Traditionally two types of modelling are used in pedagogical research, verbal and conceptual ones. The former is the verbal expression of the ideas; the latter is their graphical mapping. The present article is an attempt to support the principles of (...) the evolutionary modelling in the research of the development of the system of professional education. Theoretical analysis. Interpretation of the terminology of the classical theory of evolution shows that there are analogues of the biological processes of heredity, selection, and variation in the system of professional education. Clarification of the strategies of evolutionary modelling allows applying its principles to the development of professional education. It is shown that there are possibilities to model variable development of professional education. It is pointed that any element of the system of professional education can become its growing point provided the favorable conditions are created. Some examples of the negative effects of ignoring the principles of evolutionary development are supplied. Conclusion. The conclusion is drawn that common conceptual basis and analogues of the reference notions used in the evolutionary modelling (gen, genotype, phonotype, suitability, mutation, memory, generation) lead to research professional education as a self-organizing system bearing adaptive mechanisms.

FROM HIPPOCRATIC OATH TO DECLARATION OF GENEVA: THE EVOLUTION OF ETHICAL VALUES IN MEDICAL PRACTICE.

Suppose that Sherlock Holmes has just closed another case, and is convinced that Moriarty is the perpetrator. At that very moment, Inspector Lestrade arrives to inform Holmes that a Scotland Yard analysis of his past investigations shows that he only identifies the correct suspect in 50% of cases. How should Holmes respond to this new information? This is a question about higher-order evidence. Higher-order evidence can be understood as evidence about the rationality of your beliefs, or about your reliability in (...) judging matters in a certain domain. Some views on higher-order evidence, like calibrationism, say that Holmes should drastically reduce his confidence that Moriarty is the perpetrator, in light of what he learns about his track record. Other perspectives will recommend that Holmes stick to his guns instead. This dissertation explores the nature and epistemic significance of higher-order evidence, and considers whether higher-order evidence we acquire from empirical research into human evolution might serve to undermine the justification for our moral beliefs, as evolutionary debunking arguments, like those advanced by Sharon Street and Richard Joyce, have alleged. Ultimately, I argue that the calibrationist response to higher-order evidence is the right one, and that our emerging understanding of how morality evolved does indeed pose a serious challenge to the epistemic status of our moral beliefs.

This paper presents sample results from a poll conducted among experts regarding the roots of the controversy between the evolutionary account of human origin and religious convictions about creation. It appears that the position one takes in this controversy is influenced much more by one’s opinions than professional background.

A new paradigm in theology, termed evolutionary theology, supports the understanding of ecology as the proper ordering of the relations between living organisms and their environment. It is argued that evolutionary theology yields a unique conceptual framework in which the human species share a common history with the entire Universe and respecting nature’s integrity means securing a common destiny to everything that exists. This is a powerful motivation for adopting a balanced ecological attitude aimed at respecting nature’s inherent integrity. Furthermore, (...) proposing theological arguments to substantiate ecological claims will help neutralize the objections that religion as such promotes anti-ecological attitudes. Such objections become more pressing when religion focuses exclusively on the afterlife in the immaterial and eternal world to come, and neglects the well-being of the material and temporal Universe. -------------- Received: 30/08/2020.

Despite many arduous attempts to reconcile the separation between theology and science, the common ground where these two areas of intellectual inquiry could converge has not been fully identified yet. The purpose of this paper is to use evolutionary theology as the new and unique framework in which science and theology are indeed brought into coherent alignment. The major step in this effort is to acknowledge that theology can no longer dialogue with science but must assume science and its method (...) as its conceptual foundation. This approach successfully does away with any tensions that may arise between the two disciplines and establishes a firm ground on which neither of them will turn into ideology. Moreover, it enables the dialogue with contemporary scientific atheism on solid grounds and the restoration of the credibility of theology in the secularist culture of the day. (shrink)

The phenomenon of globalization, which is well known in the economy, can nowadays be observed also in the area of science. It is based on the fact that more and more scientific disciplines are applying the same explanatory principle, namely the theory of evolution. Therefore, every development, including that of man, according to the pattern of genetic reproduction, takes place on the basis of natural selection. With psychological properties, mental abilities and social behaviours, which are eloquently referred to as “memes”, (...) it is as with genes: only those that are better, stronger, more capable of surviving will survive after accidental changes and only they will be passed on. In short, reproduction regulates and controls human behaviour. Such a way of thinking and explanation can be found today in many publications on sociobiology and evolutionary psychology. Even if they present many new details, they pay tribute to the old human desire to explain everything in a simple way, according to the same scheme. The same expectation towards science was expressed by E. Haeckel in the 19th century and J. Monod in the 20th century. However, when these two biologists explained man as a whole based on the theory of evolution, they admitted that they referred to philosophy, to which contemporary representatives of sociobiology and evolutionary psychology cannot or do not want to confess.

In this paper, I examine one of Nagel’s arguments against evolutionary theory, that the evolutionary conception of nature is incompatible with our understanding of cognition. I reconstruct Nagel’s two charges that the evolutionary conception of nature is at odds with our ability to acquire objective knowledge of the external world and that evolutionary theory is insufficient to explain logic’s absolute reliability. I reply to the first charge by suggesting that we should understand our ability to logically reason as a by-product (...) instead of a direct product of the evolutionary processes. Then I reply to the second charge by denying that logic’s reliability is an appropriate subject of inquiry the evolutionary theory. (shrink)

The goal of this paper is to defend the theory of generalized evolution (GE) against criticisms by laying down its theoretical principles and their applications in a unified way. Section 2 develops GE theory and its realization in biological evolution (BE) and cultural evolution (CE). The core of GE theory consists of the three Darwinian principles together with the models of population dynamics (PD). Section 3 reconstructs the most important differences between BE and CE. While BE is predominantly based on (...) the replication of genes, CE is based on the reproduction of memes. Memes are understood as the informational “software” of human brains transmitted through social learning processes. The ontology of memes and the concept of cultural fitness is carved out and refined. Finally, section 4 articulates the minimal ontological assumptions of GE theory and the quantitative principles of generalized PD that unify biological PD and evolutionary game theory. (shrink)

The concept of fitness is central to evolutionary biology. Models of evolutionary change typically use some quantity called “fitness” which measures an organism’s reproductive success. But what exactly does it mean that fitness is such a measure? In what follows, we look at the interplay between abstract evolutionary models and quantitative measures of fitness and develop a measurement-theoretic perspective on fitness in order to explore what makes certain measures of fitness significant.
