Evolutionary Biology

How is moral thinking, ethics, related to evolutionary theorizing? There are two approaches, epitomized by Charles Darwin who works under the metaphor of the world as a machine, and by Herbert Spencer who works under the metaphor of the world as an organism. Although the author prefers the first approach, the aim of this paper is to give a disinterested account of both approaches.

This article argues that the Indian philosopher-mystic Sri Aurobindo espoused a sophisticated form of cosmopsychism that has great contemporary relevance. After first discussing Aurobindo’s prescient reflections on the “central problem of consciousness” and his arguments against materialist reductionism, I explain how he developed a panentheistic philosophy of “realistic Adwaita” on the basis of his own spiritual experiences and his intensive study of the Vedāntic scriptures. He derived from this realistic Advaita philosophy a highly original doctrine of evolutionary cosmopsychism, according to (...) which the Divine Saccidānanda is “involved” in everything in the universe and gradually manifests itself at each stage of the evolutionary process from matter to life to mind, and ultimately, to Supermind—the final stage that is yet to come, upon the attainment of which we will attain knowledge of our true divine nature as Saccidānanda. I then reconstruct Aurobindo’s novel solution to the individuation problem, according to which the Divine Saccidānanda individuates into various distinct consciousnesses by playfully limiting itself through a process of “exclusive concentration.” Finally, I highlight the continued relevance of Aurobindo’s evolutionary cosmopsychism by bringing him into conversation with Itay Shani, a contemporary proponent of cosmopsychism.

The relationship between corporate social responsibility and leadership has received considerable research attention in recent decades. While there have been several qualitative reviews, quantitative and systematic reviews of CSR–leadership links remain absent. The current paper seeks to address this gap by using a bibliometric method to analyze and visualize the evolution and research trends within the CSR–leadership domain. Drawing from a sample of 1432 peer-reviewed articles, we map the landscape of the CSR–leadership research domain and identify key developments and patterns (...) over the period 1994–2020. In addition to highlighting a range of publication trends including key theoretical influences, the findings also reveal an acceleration in the volume and breadth of CSR–leadership research. Seven subdomains are further identified and discussed based on the keywords using the log-likelihood ratio clustering algorithm. The analysis is further divided into three stages: namely, the initial stage, the rapid development stage, and the maturation stage. These stages are used to present more fine-grained insights into the research patterns over time. We conclude by discussing implications of the bibliometric analysis and presenting several opportunities for future research. (shrink)

To understand Darwin’s concept of natural selection, we have to contrast it with his characterization of artificial selection, and then ask: what is natural in natural selection? While we do this, we develop two distinctions: one between ‘change by transformative action’ and ‘change by selection’, and another between ‘artificial selection’ and ‘natural selection’. The first distinction helps us understand evolution by selection and the second natural selection.

Both biosemiotics and evolutionary epistemology are concerned with how knowledge evolves. (Applied) Evolutionary Epistemology thereby focuses on identifying the units, levels, and mechanisms or processes that underlie the evolutionary development of knowing and knowledge, while biosemiotics places emphasis on the study of how signs underlie the development of meaning. We compare the two schools of thought and analyze how in delineating their research program, biosemiotics runs into several problems that are overcome by evolutionary epistemologists. For one, by emphasizing signs, biosemiotics (...) needs to delineate a semiotic threshold, which is a problem not encountered by evolutionary epistemologists. Instead, the latter recognizes that all organisms are knowers that evolve knowledge, which they recognize to extend toward phenomena produced by organisms such as behavior, cognition, language, culture, science, and technology. Secondly, biosemiotics attempts at continuing adaptationist notions on how organisms relate to their environment, while especially Applied Evolutionary Epistemology comes to redefine the nature of the organism–environment relationship in such a way that it recognizes the spatiotemporal boundedness of existence, which in turn makes adaptationist accounts obsolete.

Trevor Pearce has done something remarkable and all too rare: written a book at the intersection of philosophy, science, and history that is equally excellent in all three respects.

We formalize the notion of isolated objects, and we build a consistent theory to describe their evolution and interaction. We further introduce a notion of indistinguishability of distinct spacetime paths of a unit, for which the evolution of the state variables of the unit is the same, and a generalization of the equivalence principle based on indistinguishability. Under a time reversal condition on the whole set of indistinguishable paths of a unit, we show that the quantization of motion of spinless (...) elementary particles in a general potential field can be derived in this framework, in the limiting case of weak fields and low velocities. Extrapolating this approach to include weak relativistic effects, we explore possible experimental consequences. We conclude by suggesting a primitive ontology for the theory of isolated objects.

I respond to Michał Chaberek’s and Robert A. Delfino’s criticisms of my argument that evolution is compatible with Aristotelian-Thomistic metaphysics. Biological species, as secondary substances, are beings of reason founded in the natures of their instances. They are traceable to God’s creative intent, but not to universal exemplars. Aquinas teaches that concepts are derived from sensible accidents. Thus, evolution’s directed variation of such accidents will eventually require new species concepts. This accords with projective realism, which allows diverse, well-founded concepts based (...) on the multiple perspectives and conceptual spaces of knowing subjects. Charges that this is nominalism, not moderate realism, are rebutted; however, it is relativism because knowledge is a subject-object relation. Other metaphysical issues are considered. Chaberek’s thesis that species cannot evolve naturally fails because he: reifies the species concept, misrepresents the motivation, structure and conclusions of evolution, confuses Aristotle’s four causes and limits God’s creative omnipotence. Finally, Chaberek is out of step with contemporary theology. (shrink)

Evolutionary psychology offers a fairly ‘patriarchal’ picture of sex differences, according to which men are, ‘by nature’, much more polygamously disposed, much more desirous of power over the opposite sex, and much more aggressive than women. However, the picture – at least in its components and – becomes problematic if one looks at the history of conceptions of paternity accepted by our ancestors. It is argued in the paper that the very fact that our ancestors accepted various and essentially different (...) conceptions of paternity casts a shadow of doubt on the ‘patriarchal’ picture of sex differences.

This paper deals with the evolutionary origin and the adaptive function of emotion. I discuss the view that emotions have evolved as functional adaptations in both humans and non-human animals in order to cope with adaptive challenges and to promote fitness. I argue that there is evolutionary continuity between humans and animals in emotions and emotional expressions, and discuss behavioural argument for this thesis, specifically, Darwin’s and Ekman’s research on similarities in how humans and animals express their basic emotions. In (...) addition to this argument, I provide neuroscientific evidence that supports the claim that basic emotions are evolutionary old and shared among humans and many other animals. Finally, I conclude that animal emotions can be considered the bases and roots of our emotions that connect us to other sentient beings. (shrink)

A common line of reasoning that argues against teleological conjectures in physics, cosmology, and especially evolutionary biology, resorts to statistical concepts based on notions of randomness, unpredictability or chance. A conceptual relationship between the aleatory uncertainty of a process and its inherent lack of goal-directedness is often taken for granted. This relies on a misunderstanding of the real significance of stochastic concepts importing a popular semantics into scientific considerations, which leads to unwarranted conclusions. We felt it necessary to clarify terms (...) and concepts involving stochastic processes and why there is no mutual exclusivity between randomness in the physical world and conjectures involving teleological arguments in physics and evolution envisaging a goal-driven and conscious universe.

Paleontological evidence suggests that human artefacts with intentional markings might have originated already in the Lower Paleolithic, up to 500.000 years ago and well before the advent of ‘behavioural modernity’. These markings apparently did not serve instrumental, tool-like functions, nor do they appear to be forms of figurative art. Instead, they display abstract geometric patterns that potentially testify to an emerging ability of symbol use. In a variation on Ian Hacking’s speculative account of the possible role of “likeness-making” in the (...) evolution of human cognition and language, this essay explores the central role that the embodied processes of making and the collective practices of using such artefacts might have played in early human cognitive evolution. Two paradigmatic findings of Lower Paleolithic artefacts are discussed as tentative evidence of likenesses acting as material scaffolds in the emergence of symbolic reference-making. They might provide the link between basic abilities of mimesis and imitation and the development of modern language and thought. (shrink)

The main thesis that is discussed in this article is based on the criticism of the prevalent interpretative models of adolescence developed during the twentieth century. Models that today appear inadequate in grasping the socio-cultural and educational transformations that deeply mark the ways of experiencing adolescents born in the second millennium. The effects of the historical and social practices that shape the adolescent experience in the 2000s represent an essential key to understanding the forms that the adolescent system assumes because (...) of social, cultural, economic, historical, and material changes.

The complex relations between Christianity and science seem to present a critical point in evolutionary theory, especially for the challenges it poses to the doctrine of original sin. I investigate the precise senses in which evolution threatens the Augustinian/Reformed formulation of original sin, analyzing each of the six tenets of the doctrine vis a vis nine evolutionary claims, as well as the supposed clash between the narratives of evolution and Christianity. I show that the threat is less impressive than it (...) is usually assumed, and I highlight where the conflict really lies. I defend that it is possible to remain faithful to the core of the doctrine of original sin and to accept the reliability of evolution as a scientific theory. I present three scenarios for “Adam and Eve” and interpret them using two different models. I favor the understanding of Adam and Eve as the whole initial human bottleneck viewed through the lens of a multilevel model. (shrink)

Evolutionary Transitions in Individuality have been responsible for the major transitions in levels of selection and individuality in natural history, such as the origins of prokaryotic and eukaryotic cells, multicellular organisms, and eusocial insects. The integrated hierarchical organization of life thereby emerged as groups of individuals repeatedly evolved into new and more complex kinds of individuals. The Social Protocell Hypothesis proposes that the integrated hierarchical organization of human culture can also be understood as the outcome of an ETI—one that produced (...) a “cultural organism” from a substrate of socially learned traditions that were contained in growing and dividing social communities. The SPH predicts that a threshold degree of evolutionary individuality would have been achieved by 2.0–2.5 Mya, followed by an increasing degree of evolutionary individuality as the ETI unfolded. We here assess the SPH by applying a battery of criteria—developed to assess evolutionary individuality in biological units—to cultural units across the evolutionary history of Homo. We find an increasing agreement with these criteria, which buttresses the claim that an ETI occurred in the cultural realm. (shrink)

According to anthropological philosopher René Girard, an important human adaptation is our propensity to victimize or scapegoat. He argued that other traits upon which human sociality depends would have destabilized primate dominance-based social hierarchies, making conspecific conflict a limiting factor in hominin evolution. He surmised that a novel mechanism for inhibiting intragroup conflict must have emerged contemporaneously with our social traits, and speculated that this was the tendency to spontaneously unite around the victimization of single individuals. He described an unconscious (...) tendency to both ascribe blame and to imbue the accused with a sacred mystique. This emotionally cathartic scapegoat mechanism, he claimed, enhanced social cohesion, and was the origin of religion, mythology, sacrifice, ritual, cultural institutions, and social norms. It would have functioned by modifying the beliefs and behaviors of the group, rather than of the accused, making the act of accusation more important than the substance. This article aims to examine the empirical evidence for Girard’s claims, and argues that the scapegoat hypothesis has commonalities with several other evolutionary hypotheses, including Wrangham’s execution hypothesis on self-domestication, Dunbar’s hypothesis on the role of storytelling in maintaining group stability, and DeScioli and Kurzban’s hypothesis on the role of non-consequentialist morality in curtailing conflict. Potential implications of the scapegoat hypothesis for evolutionary psychology and psychiatry are discussed. (shrink)

In enhancement ethics, evolutionary theory has been largely perceived as supporting liberal views on enhancement, where decisions to enhance are predominantly regulated by the principle of individual autonomy. In this paper I critique this perception in light of recent scientific developments. Cultural evolutionary theory suggests a picture where individual interests are entangled with community interests, and this undermines the applicability of the principle of autonomy. This is particularly relevant for enhancement ethics, given how – I argue – decisions to enhance (...) are often influenced by desires to increase social status. The “service view on enhancement”, based on principles of service and trust, is proposed as offering better guidance for the challenges of social living. (shrink)

This is an English translation of the French editor's preface to The Evolution of the Problem of Freedom, which is the first course Bergson taught as the chair in the “History of Modern Philosophy” at the Coll è ge de France.

In his numerous books and articles, Leszek Kołakowski brought up a number of topics in the fields of the history of philosophy and contemporary philosophy. His work offers valuable insights into problems revolving around Karl Marx’s philosophy, social philosophy, and the philosophy of religion, to mention but a few. In all these areas of thought, the Polish philosopher centres his focus on the fundamental question of man. The present paper is aimed at discussing Leszek Kołakowski’s contribution to the philosophical debate (...) on this topic. The evolution of Kołakowski’s views is traced from the Marxist concept of man which, after a certain period, is discarded by the philosopher in favour of a religious concept, to be confronted again with a liberal theory. Kołakowski is not uncritical about any of the conceptions, which testifies to the profound complexity of every attempt to gain insights into the very essence of the human being which, irrespective of the doctrine or perspective taken for interpretation, escapes clear-cut definition. However, despite the lack of unambiguous definitions Kołakowski recognises that the sole point of reference in any attempts to gain an understanding of the human condition in culture is religion.

In this article I argue that we should pay extra attention to the ecological dimension of natural selection. By this I mean that we should view natural selection primarily as acting on the outcomes of the interactions organisms have with their environment, which influences their relative reproductive output. A consequence of this view is that natural selection is not sensitive to what system of inheritance ensures reoccurrences of organism-environment interactions over generations. I end by showing the consequences of this view (...) when looking at how processes like niche construction and the Baldwin effect relate to natural selection. (shrink)

Evolutionary accounts of morality consider behavior in rather simple scenarios. Evolutionary work on fairness focuses on the division of a windfall and, importantly, assumes that the positions of those involved are entirely symmetric. I consider more complicated strategic settings and find that there is a strong tendency for evolution to produce divisions consistent with the so-called Nash bargaining solution. I also uncover the evolutionary importance of comprehensiveness, an often-overlooked feature of division problems.

Die Beziehung der Entwicklung des Lebens im Weltall - von den einfachsten Formen bis zu Leben mit Geist und Bewusstsein – zu der Physik, wie wir sie aus der unbelebten Natur kennen, ist Thema dieses Essays. Ist die Entstehung des Lebens Zufall, ist es Folge einer physikalischen Logik, die noch zu entdecken ist, oder ist „Lebensfreundlichkeit“ ein eigenes Prinzip des Naturgeschehens, das zum Beispiel offene Naturkonstanten der physikalischen Gesetze festlegt, zu denen die geheimnisvollen Grossen Zahlen der Kosmologie gehören – „The (...) Lore of Large Numbers…“? Wissenschaftlich bleibt diese Frage nicht eindeutig zu klären; intuitiv wird das „Prinzip lebensfreundlich“ der menschlichen Evolution wohl am ehesten gerecht. Dabei ist „lebensfreundlich“ in diesem Artikel nicht psychologisch im Sinne menschlicher Beziehungen gemeint, sondern eine Art Kurzbezeichnung für eine Physik, die im Kosmos irgendwann und irgendwo Leben, auch menschliches Leben mit Geist und Bewusstsein ermöglicht. Der Artikel ergänzt auch Texte des Autors über Physik und Bewusstsein, um physikalische und anthropologische Aspekte der Kosmologie (unter philpapers im Volltext). (shrink)

The Rise of Chance in Evolutionary Theory: A Pompous Parade of Arithmetic explores a pivotal conceptual moment in the history of evolutionary theory: the development of its extensive reliance on a wide array of concepts of chance. It tells the history of a methodological and conceptual development that reshaped our approach to natural selection over a century, ranging from Darwin’s earliest notebooks in the 1830s to the early years of the Modern Synthesis in the 1930s. Far from being a “pompous (...) parade of arithmetic,” as one early critic argued, evolution transformed during this period to make these conceptual and technical tools indispensable. This book charts the role of chance in evolutionary theory from its beginnings to the earliest days of modern evolutionary theory, making it an ideal resource for evolutionary biologists, historians, philosophers, and researchers in science studies or biological statistics.

Both Medawar and Hamilton contributed key ideas to the modern evolutionary theory of ageing. In particular, they both suggested that, in populations with overlapping generations, the force with which selection acts on traits declines with the age at which traits are expressed. This decline would eventually cause ageing to evolve. However, the biological literature diverges on the relationship between Medawar’s analysis of the force of selection and Hamilton’s. Some authors appear to believe that Hamilton perfected Medawar’s insightful, yet ultimately erroneous (...) analysis of this force, while others see Hamilton’s analysis as a coherent development of, or the obvious complement to Medawar’s. Here, the relationship between the two analyses is revisited. Two things are argued for. First, most of Medawar’s alleged errors that Hamilton would had rectified seem not to be there. The origin of these perceived errors appears to be in a misinterpretation of Medawar’s writings. Second, the mathematics of Medawar and that of Hamilton show a significant overlap. However, different meanings are attached to the same mathematical expression. Medawar put forth an expression for the selective force on age-specific fitness. Hamilton proposed a full spectrum of selective forces each operating on age-specific fitness components, i.e. mortality and fertility. One of Hamilton’s expressions, possibly his most important, is of the same form as Medawar’s expression. But Hamilton’s selective forces on age-specific fitness components do not add up to yield Medawar’s selective force on age-specific fitness. It is concluded that Hamilton’s analysis should be considered neither as a correction to Medawar’s analysis nor as its obvious complement. (shrink)

Recent evolutionary studies on cooperation devote specific attention to non-verbal expressions of emotions. In this paper, I examine Robert Frank’s popular attempt to explain emotions, non-verbal markers and social behaviours. Following this line of work, I focus on the green-beard explanation of social behaviours. In response to the criticisms raised against this controversial ultimate explanation, based on resources found in Frank’s work, I propose an alternative red-beard explanation of human sociality. The red-beard explanation explains the emergence and evolution of emotions, (...) a proximate cause, rather than patterns of behaviour. In contrast to simple evolutionary models that invoke a green-beard mechanism, I demonstrate that the red-beard explanation can be evolutionary stable. Social emotions are a common cause of a social behaviour and a phenotypic marker and therefore cooperative behaviour cannot be suppressed without also changing the marker. (shrink)

This coherent collection of original papers marks the 150 year anniversary since the publication of Charles Darwin's Origin of Species (1859). Although the area of evolution-related publications is vast, the area of interaction between Darwinian ideas and specifically Catholic doctrine has received limited attention. This interaction is quite distinct from the one between Darwinism and the Christian tradition in general. Interest in Darwin from the Catholic viewpoint has recently been rekindled. Endorsement: “As this volume shows, any notion of intractable conflict (...) between faith and reason is an extremist fantasy. The true depth of religious thought on Darwin's great idea not only shows respect for science, but a deep appreciation for the esthetic beauty of evolutionary thought. These challenging and enlightening essays demonstrate not only the power of scientific reasoning, but a continuing Catholic commitment to the ultimate unity of knowledge.” — Kenneth R.

This volume examines the limitations of mathematical logic and proposes a new approach to logic intended to overcome them. To this end, the book compares mathematical logic with earlier views of logic, both in the ancient and in the modern age, including those of Plato, Aristotle, Bacon, Descartes, Leibniz, and Kant. From the comparison it is apparent that a basic limitation of mathematical logic is that it narrows down the scope of logic confining it to the study of deduction, without (...) providing tools for discovering anything new. As a result, mathematical logic has had little impact on scientific practice. Therefore, this volume proposes a view of logic according to which logic is intended, first of all, to provide rules of discovery, that is, non-deductive rules for finding hypotheses to solve problems. This is essential if logic is to play any relevant role in mathematics, science and even philosophy. To comply with this view of logic, this volume formulates several rules of discovery, such as induction, analogy, generalization, specialization, metaphor, metonymy, definition, and diagrams. A logic based on such rules is basically a logic of discovery, and involves a new view of the relation of logic to evolution, language, reason, method and knowledge, particularly mathematical knowledge. It also involves a new view of the relation of philosophy to knowledge. This book puts forward such new views, trying to open again many doors that the founding fathers of mathematical logic had closed historically. (shrink)

We propose an approach reconciling the ultimate-level explanations proposed by Savage et al. and Mehr et al. as to why music evolved. We also question the current adaptationist view of culture, which too often fails to disentangle distinct fitness benefits.

Both the music and social bonding hypothesis and the music as a credible signal hypothesis emerge as solid views of how human music and human musicality might have evolved. Nonetheless, both views could be improved with the consideration of the way in which human language might have evolved under the effects of our self-domestication.

ABSTRACT Although natural philosophy underwent dramatic transformations during the seventeenth and eighteenth centuries, studying its evolution as a whole remains problematic. In this paper, we present a method that integrates traditional reading and computational tools in order to distil from different resources a representative corpus for mapping the evolution of natural philosophy. In particular, we focus on gathering authors and works that were engaged with the teaching of natural philosophy in the early modern academic milieu. We offer a preliminary assessment (...) of the relevance of our corpus by investigating one aspect of this evolution, namely the trends in the acknowledgments of authorities linked with different and competing approaches to natural philosophy. The results not only corroborate existing knowledge, but they also show distinctive features and differences within these trends that were not observed previously, thus illustrating the heuristic potential of our computational method for corpus collection.
