-/- Policy regulations of ethically controversial genetic technologies should, on the one hand, be based on ethical principles. On the other hand, they should be socially acceptable to ensure implementation. In addition, they should align with ethical theory. Yet to date we lack a reliable and valid scale to measure the relevant ethical judgements in laypeople. We target this lacuna. -/- We developed a scale based on ethical principles to elicit lay judgments: the Genetic Technologies Questionnaire (GTQ). In two pilot (...) studies and a pre-registered main study, we validated the scale in a representative sample of the US population. -/- The final version of the scale contains 20 items but remains highly reliable even when reduced to five. It also predicts behaviour; for example, ethical judgments as measured by the GTQ predicted hypothetical donations and grocery shopping. In addition, the GTQ may be of interest to policymakers and ethicists because it reveals coherent and ethically justified judgments in laypeople. For instance, the GTQ indicates that ethical judgments are sensitive to possible benefits and harms (in line with utilitarian ethics), but also to ethical principles such as the value of consent-autonomy. -/- In conclusion, the GTQ can be recommended for research in both experimental psychology and applied ethics, as well as a tool for ethically and empirically informed policymaking.

How we ought to diagnose, categorise and respond to spectrum disabilities such as autism and Attention Deficit/Hyperactivity Disorder (ADHD) is a topic of lively debate. The heterogeneity associated with ADHD and autism is described as falling on various continua of behavioural, neural, and genetic difference. These continua are varyingly described either as extending into the general population, or as being continua within a given disorder demarcation. Moreover, the interrelationships of these continua are likewise often vague and subject to diverse (...) interpretations. -/- In this paper, I explore geneticists' and self-advocates’ perspectives concerning autism and ADHD as continua. These diagnoses are overwhelmingly analysed as falling on a continuum or continua of underlying traits, which supports the notion of “the neurodiversity spectrum”, i.e., a broader swath of human neural and behavioural diversity on which some concentrations of different functioning are diagnosed. I offer a taxonomy of conceptions of the genetic, phenotypic, and endophenotypic dimensionality within and beyond these diagnostic categories, and suggest that the spectrum of neurodiversity is characteristically endophenotypic.

The UK government decided to introduce Income Tax in 1799. Later, tax avoidance schemes involved creation of Deeds of Convenant. It is a fact that crime is increasing but the number of people committing crime is not increasing because many crimes are repeated crimes committed by persons with habitual criminal behaviour, ie hard-core criminals. -/- For more than half a century now, there has been scientific evidence that genetics plays a key role in the origins of criminal behaviour. There (...) are many ethical considerations thus raised which governments are reluctant to face and which, if faced, will cost a lot in financial terms to implement and to also dismantle the old entrenched systems -/- As the author states, genetics is considered in evidence only in federal United States ; New Zealand and Australia and not in the United Kingdom, although the UK’s Criminal Justice Act 2003 does, in some circumstances, allow evidence from relatives about the defendant’s character, but this is not expert evidence but merely non-expert opinion, permitted in relation to the defendant’s bad character in circumstances as per s 101 CJA 2003. Note that in the US, the Federal Rules of Evidence Rule 402 prevents the submission of irrelevant evidence. -/-. (shrink)

Gregor Mendel (1822-1884) was the first to explain that certain 'traits' were inherited in plants from one generation to the next. These would later become known as genes. Frederich Miescher in 1869 analyzed a substance from the nucleus of cells, which he therefore called nuclein. Further study of nuclein revealed that it contained elements like hydrogen, oxygen, nitrogen and phosphorous, with a specific ratio of nitrogen to phosphorous. Then in 1878 Albrecht Kossel determined that nuclein contained nucleic acid, from which (...) he isolated five nucleobases (nitrogen compounds now referred to by the letters C, G, A, T, U representing cytosine, guanine, adenine, thymine, and uracil). It was also discovered that ribose, a sugar was present in the nuclein compound. What Miescher had isolated from the cell nucleus was actually what would latter be identified as DNA (Deoxyribonucleic acid). C. H. Waddington (1905 - 1975) first proposed the term “epigenetics” in 1942 to describe the region between the gene and the whole organism (phenotype) [3]. Today, what is called the epigenome refers to all the chromosomal modifications, DNA modifications, chromatin protein modifications and their complexes. It is the epigenome that determines both the expression of the genes and their inheritance. R. A. Jorgenson reports [4], "Many of these modifications appear to be “programmable” and to be “read out” to influence chromosomal functions." Nobel laureate Barbara McClintock stated this revolutionary proposal more clearly in her Nobel lecture [5], “to determine the extent of knowledge the cell has of itself, and how it utilizes this knowledge in a ‘thoughtful’ manner when challenged.” In 1960 R. A. Brinks suggested that chromosomes possess a paragenetic function in addition to their genetic function [7]. The physical nature of the paragenetic function is characterized by the variety of forms or states of chromatin that can reside at any genetic locus. While the genetic function is stable, the paragenetic function is labile and programmable in ontogeny. It is this latter function that allows organisms to transfer informational macromolecules (RNA and proteins) in a systematic and regulated manner over what is known as the “RNA information superhighway.” Given this capacity, organisms may be able to store information at numerous genetic loci in the form of paragenetic chromatin states, which can be reprogrammed during ontogeny or environmental stress [8]. This reprogrammable system could operate over the whole organism as a storage device, allowing it to make informed ‘decisions' during growth and development, or in response to the environment. Such processing capacity could be considered a form of ‘intelligence,' which also could be passed on to future generations. The study of the flow of information within and between cells and organisms represents the cutting edge of modern biological research. While physical correlates of cognitive behavior in living organisms are being discovered, it does not spell reduction to such correlates. The electronic activity within the physical components of a radio, for example, may be minutely determined, but ultimately it is not merely the electrical activity that produces the intelligent speech that is heard. Only the intelligent person whose voice is being broadcast through the radio can explain that. Without the broadcaster, the radio would sit silently even though fully functional. An organism without its living agency also appears to be devoid of metabolic activity although all the chemical components are fully present. How to connect life to matter will be the ultimate challenge that has to be met. This will prove to be a philosophical problem we hope to address in the near future. (shrink)

Current knowledge of the RNA world indicates 2 different genetic codes being present throughout the living world. In contrast to non-coding RNAs that are built of repetitive nucleotide syntax, the sequences that serve as templates for proteins share—as main characteristics—a non-repetitive syntax. Whereas non-coding RNAs build groups that serve as regulatory tools in nearly all genetic processes, the coding sections represent the evolutionarily successful function of the genetic information storage medium. This indicates that the differences in their syntax structure are (...) coherent with the differences of the functions they represent. Interestingly, these 2 genetic codes resemble the function of all natural languages, i.e., the repetitive non-coding sequences serve as appropriate tool for organization, coordination and regulation of group behavior, and the nonrepetitive coding sequences are for conservation of instrumental constructions, plans, blueprints for complex protein-body architecture. This differentiation may help to better understand RNA group behavioral motifs. (shrink)

This review is unashamedly from the perspective of English law because busy United Kingdom criminal law solicitors and barristers mostly wish to know what the law states, which case is a precedent case and whether the author has provided up-to-date legal information. This is because legal practitioners deal with real and urgent cases. The English Income Tax Act gained Royal Assent in 1799 the first government attempt to stop early tax avoidance. Later, tax avoidance schemes (which in English Law were (...) deemed a legitimate method of minimising one payment of taxation) became de rigueur all over the world and often involved creation of Deeds of Covenant and Trusts, notably Discretionary Trusts under civil law. Man’s ingenuity knows no bounds and this applies to man’s characteristic of criminality as it does to scholarship, enterprise and innovation. Despite protestations by some countries police agencies, contrary to the rise of crime, the fact is that that crime is increasing exponentially worldwide, but the number of people committing crime is not increasing because many crimes are repeated crimes committed by persons with habitual criminal behaviour, ie hard-core criminals.

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

In February 1994, Stephen Mobley was convicted of the murder of John Collins. Mobley's lawyers attempted to introduce genetic evidence in an attempt to have Mobley's sentence reduced from death to life imprisonment. I examine the prospects for appeal to genetic determinism as a criminal defense. Guided by existing standards for insanity defenses, I argue that a genetic defense might be allowable in exceptional cases but will not be generally available as some have worried.

Griffiths and Stotz’s Genetics and Philosophy: An Introduction offers a very good overview of scientific and philosophical issues raised by present-day genetics. Examining, in particular, the questions of how a “gene” should be defined and what a gene does from a causal point of view, the authors explore the different domains of the life sciences in which genetics has come to play a decisive role, from Mendelian genetics to molecular genetics, behavioural genetics, and (...) evolution. In this review, I highlight what I consider as the two main theses of the book, namely: genes are better conceived as tools; genes become causes only in a context. I situate these two theses in the wider perspective of developmental systems theory. This leads me to emphasize that Griffiths and Stotz reflect very well an on going process in genetics, which I call the “epigenetization” of genetics, i.e., the growing interest in the complex processes by which gene activation is regulated. I then make a factual objection, which is that Griffiths and Stotz have almost entirely neglected the perspective of ecological developmental biology, and more precisely recent work on developmental symbioses, and I suggest that this omission is unfortunate in so far as an examination of developmental symbioses would have considerably strengthened Griffiths and Stotz’s own conclusions.

Behavioral genetic (BG) research has yielded many important discoveries about the origins of human behavior, but offers little insight into how we might improve outcomes. We posit that this gap in our knowledge base stems in part from the epidemiologic nature of BG research questions. Namely, BG studies focus on understanding etiology as it currently exists, rather than etiology in environments that could exist but do not as of yet (e.g., etiology following an intervention). Put another way, they focus exclusively (...) on the etiology of “what is” rather than “what could be”. The current paper discusses various aspects of this field-wide methodological reality, and offers a way to overcome it by demonstrating how behavioral geneticists can incorporate an experimental approach into their work. We outline an ongoing study that embeds a randomized intervention within a twin design, connecting “what is” and “what could be” for the first time. We then lay out a more general framework for a new field—experimental BGs—which has the potential to advance both scientific inquiry and related philosophical discussions. (shrink)

Objective. We investigated associations between adults’ beliefs about the heritability of virtue and endorsements of the efficacy of specific parenting styles. Design. In Studies 1 (N = 405) and 2 (N = 400), beliefs about both the genetic etiology of virtuous characteristics and parenting were assessed in samples of parents and non-parents. In Study 3 (N = 775), participants were induced to view virtue as determined by genes or as determined by social factors. Heritability beliefs and authoritarian parenting endorsements were (...) subsequently measured. Results. Study 1 and Study 2 converged to reveal that tendencies to view characteristics as determined by genes were positively associated with endorsement of authoritarian parenting styles. This association occurred independent of individual differences in essentialism and rightwing authoritarianism. Study 3 revealed that exposure to genetic accounts of virtue increased beliefs that virtue is caused by genes, which in turn was positively associated with endorsements of authoritarian parenting responses to child problem behavior. Exposure to genetic accounts of virtue increased endorsement of authoritarian parenting among parents, but was unrelated to authoritarian parenting among non-parents. Conclusions. These studies suggest that genetic accounts of virtuous characteristics reliably relate to more positive beliefs about harsh and controlling parenting practices, illuminating an unrecognized cognitive factor associated with authoritarian parenting endorsement.

The theoretical heuristic of assuming distinct alleles (or genotypes) for alternative phenotypes is the foundation of the paradigm of evolutionary explanation we call the Modern Synthesis. In modeling the evolution of sociality, the heuristic has been to set altruism and selfishness as alternative phenotypes under distinct genotypes, which has been dubbed the “phenotypic gambit.” The prevalence of the altruistic genotype that is of lower evolutionary fitness relative to the alternative genotype for non-altruistic behavior in populations is the basis of the (...) “paradox of altruism.” I show in this article that the assumption of contrasting genotypes for altruism and selfishness in our “phenotypic gambit” is inconsistent with the empirical data when viewed in the light of today’s post-Mendelian understanding of gene expression. I demonstrate that however nuanced and sophisticated the models may have become today, they are still rooted in that fundamentally problematic assumption. I then offer a genetic conception of altruism that best fits the field data. (shrink)

This paper is trying to put together two different researches, from theology and from genetics, about a general and undetermined topic, death. It is undetermined because no one can say something demonstrable and unequivocal about it, since no person alive can cross over the edge of life and come back from the domain of death with information about it. But we can discuss nevertheless things that are obvious and possible to be reasonably inferred about death even by livings. In (...) this regard Theology will provide the mainline of what is to be known as death for religion in general, while Genetics will try to come with its research to sustain or contradict the general premise: death is not an ontological behavior of living matter, but an imposed attribute after the sin occurred into the world.

Both the genetic endowment we have been equipped with, and the environment we had to be born and raised in, were not – and never are – for us to choose; both are pure luck, a random ticket in this enormously inventive cosmic lottery of existence. If it is luck that has makes us the persons we are, and since our decisions and choices depend largely on the kind of persons we are, it seems that everything we do or fail (...) to do may only be attributed to luck. This paper focuses on criminal behavior, with special emphasis on Tarde’s and Lombroso’s views, to discuss free will and agency, and their interplay with moral luck, that is, the fixed boundaries set by our nature and the circumstances that surround us.

Recent trends in psychiatry involve a transition from categorical to dimensional frameworks, in which the boundary between health and pathology is understood as a difference in degree rather than as a difference in kind. A major tenet of dimensional approaches is that no qualitative distinction can be made between health and pathology. As a consequence, these approaches tend to characterize such a threshold as pragmatic or conventional in nature. However, dimensional approaches to psychopathology raise several epistemological and ontological issues. First, (...) we review major sources of evidence usually recruited in support of the dimensional trend (focusing on clinical observation and biological data), and we show that these are connected to different conceptualizations of how dimensional traits extend across health and pathology. Second, we criticize two unquestioned assumptions that stand at the core of the dimensional trend: a) that there is continuity from health to pathology at the symptomatic level; b) that such continuity reflects an underlying continuity in the genetic liability for pathological conditions. Third, we argue against the idea of a conventional threshold by showing that such a view implies a linear relationship between the genotype and the phenotype. Fourth, drawing on epigenetics and developmental biology, we offer a characterization of mental disorders as stable and dynamic constellations of multi-level variables that differ qualitatively from ‘healthy states’. We conclude by showing that our account has several theoretical advantages over both categorical and dimensional approaches. Notably, it provides crucial insights into psychological development over time and individual differences, with major implications in terms of intervention and clinical decision-making. (shrink)

Aspects of human symbolic evolution are studied by scholars active in a variety of fields and disciplines in the life and the behavioral sciences as well as the scientific-philosophical, sociological, anthropological, and linguistic sciences. These fields and disciplines all take on an evolutionary approach to the study of human symbolism, but scholars disagree in their theoretical and methodological attitudes. Theoretically, symbolism is defined differentially as knowledge, behavior, cognition, culture, language, or social group living. Methodologically, the diverse symbolic evolution sciences establish (...) their teachings upon diverging evolutionary biological schools and paradigms. This chapter reviews past and current research fields in human symbolic evolution for how they differentially implement tenets of the major evolution schools that were discussed in the previous chapter. Traditional evolutionary epistemology and biosemiotics bring in a mesoevolutionary outlook by drawing on early Darwinism and evolutionary developmental biology movements that emphasize the role of the organism in evolution. Communication studies instead originally take on a microevolutionary perspective by investigating how units of information are transmitted across generations through time. Only later do they integrate studies on meaning-making at the organismal level. Sociobiology complements a microevolutionary with a macroevolutionary outlook by implementing population genetic approaches, typical of the Modern Synthesis, into studies on individual and group behavior. The new symbolic evolutionary sciences build upon these traditions and include disciplines such as evolutionary psychology, evolutionary linguistics, evolutionary anthropology, evolutionary archaeology, evolutionary sociology, and evolutionary economics. Originally centered on implementing Darwinian selection theory, these fields are now including ecological and evolutionary developmental biology as well as reticulate evolutionary paradigms. As diverse in outlook and scope as they are, no discipline holds a privileged position over the other and all have made valuable contributions to our understanding of human symbolic evolution.

The genomics “revolution” is spreading. Originating in the molecular life sciences, it initially affected a number of biomedical research fields such as cancer genomics and clinical genetics. Now, however, a new “wave” of genomic bioinformation is transforming a widening array of disciplines, including those that address the social, historical and cultural dimensions of human life. Increasingly, bioinformation is affecting “human sciences” such as psychiatry, psychology, brain research, behavioural research (“behavioural genomics”), but also anthropology and archaeology (“bioarchaeology”). Thus, (...) bioinformatics is having an impact on how we define and understand ourselves, how identities are formed and constituted, and, finally, on how we (on the basis of these redefined identities) assess and address some of the more concrete societal issues involved in genomics governance in various settings. This article explores how genomics and bioinformation, by influencing research agendas in the human sciences and the humanities, are affecting our self-image, our identity, the way we see ourselves. The impact of bioinformation on self-understanding will be assessed on three levels: (1) the collective level (the impact of comparative genomics on our understanding of human beings as a species), (2) the individual level (the impact of behavioural genomics on our understanding of ourselves as individuals), and (3) the genealogical level (the impact of population genomics on our understanding of human history, notably early human history). This threefold impact will be assessed from two seemingly incompatible philosophical perspectives, namely a “humanistic” perspective (represented in this article by Francis Fukuyama) and a “post-humanistic” one (represented by Peter Sloterdijk). On the basis of this analysis it will be concluded that, rather than focussing on human “enhancement” by adding or deleting genes, genome-oriented practices of the Self will focus on using genomics information in the context of identity-formation. Genomic bioinformation will increasingly be built into our self-images and used in order to tailor and adapt our practices of Self to our “personalised” genome. We will keep working on ourselves, no doubt, not by modifying our genomes, but rather by fine-tuning our behaviour. What we are experiencing is a bioinformatisation of the life-world. Genomics-based technologies will increasingly pervade our daily lives, our autobiographies and narratives, as well as our anthropologies, rather than our genomes as such. (shrink)

This dissertation concerns the active role of the organism in evolutionary theory. In particular, it concerns how our conception of the relationship between organism and environment, and the nature of natural selection, influences the causal and explanatory role of organismic activity and behavior in evolutionary explanations. The overarching aim is to argue that the behaviors and activities of organisms can serve both as the explananda (that which is explained) and the explanantia (that which explains) in evolutionary explanations. I attempt to (...) achieve this aim by offering three central arguments. First, that the organism-environment relation is the ontologically basic unit of biology. A common way of conceiving the relationship between organism and environment is as a duality—as two causally independent systems that overlap through interaction. I think this is a mistake. There cannot be organisms without environments and vice versa. They are codependent and codetermined. Second, that natural selection is an ecological process. By this I mean that natural selection acts primarily on organism-environment interactions. It is only in virtue of organisms interacting with their environments that there can be fitness differences amongst individual organisms in a population. The ecological approach to natural selection also entails that the nature of the system(s) of inheritance involved in the reoccurrence of favorable organism-environment interactions is, in principle, immaterial to the process of selection. It only matters for selection that organism-environment interactions actually do reoccur in subsequent generations. Third, that niche construction theory—the most well-developed theoretical and conceptual framework for studying how the activities of organisms influences evolutionary dynamics—can be seen as fully a compatible and integrated part of evolutionary theory. Together, these three arguments constitute an overarching argument. Namely that we both can, and should, take organismic activity and behavior to be crucial explanatory elements in evolutionary theory. Throughout the dissertation I also show how these three arguments have consequences for other debates in the philosophy of evolutionary theory, such as the nature of evolutionary processes, the structure of selection-based explanations, the validity and utility of the proximate-ultimate distinction, and the nature of teleology in evolutionary systems.

Debate about legal and policy reform has been haunted by a pernicious confusion about human nature, the idea that it is a set of rigid dispositions, today generally conceived as genetic, that is manifested the same way in all circumstances. Opponents of egalitarian alternatives argue that we cannot depart far from the status quo because human nature stands in the way. Advocates of such reforms too often deny the existence of human nature because, sharing this conception, they think it would (...) prevent changes they deem desirable. Both views rest on deep errors about what it is to have a nature and how genetics works. Human nature, like the nature of anything else, is a set of potentials to behave certain ways in given environments, not a nonsocial genetic something that inevitably produces the same result in any environment. To say that existing inequalities, are due to our genes, inalterable because heritable, ignores that genetic propensities may be differently manifested in different environments. Heritability has meaning only relative to an environment and a population and implies nothing about inevitability. A better sort of inegalitarian argument is that a proposed reform, given our nature, would be too costly even if possible. However, this sort of argument is too rarely supported by evidence and generally ignores the costs of existing inequalities. But egalitarians err in supposing that, if behavior is unconstrained by biology, the status quo is easily alterable. The environment may be extremely hard to change. Legal and policy debate should adopt a correct understanding of human nature as a set of propensities and ask of any proposed reform agreed to be otherwise desirable what and how alterable are its causes, genetic, environmental, or more accurately both.

It is known that sociobiology, the theory of the biological origins of the social behavior of living beings, is related to ethics. However, sociobiology does not include moral doctrines but simply describes facts. The present essay discusses two basic theses, “altruism” and “reciprocal altruism”, in order to prove that a natural science free of judgments and evaluations is contrary to a theory of ethics, such as the theory of Kant and Apel, as well as to intuitive theories of ethics. Ethics (...) is the explanatory theory of morality, and morality should be established at the theoretical level, so that doubt can be expressed and not restrained. (shrink)

In various writings Michel Foucault has shown how, in the beginning of the 19th century, in settings such as army barracks, psychiatric hospitals and penitentiary institutions, the modern human sciences were ‹born› as an ensemble of disciplines (medical biology, psychiatry, psychology, criminology, and the like) From the beginning, the nature-nurture de- bate has been one of its key disputes. Are human individuals malleable by environmental factors (such as psychiatric treatments or disciplinary regimes), or do they rather display inborn predispositions for (...) delin- quency and other forms of antisocial behaviour? In the current era of genetic testing, in behavioural genomics and neuroscience, this issue is as controversial and topical as ever. Büchner’s unfinished drama Woyzeck (written in 1836) is a remarkable anticipation of this debate, staging the birth of the human individual as a research subject. It is the story of a destitute soldier who, according to his superiors, displays er- rant behaviour and is therefore recruited to serve as a research subject in an experiment. His army physician turns him into a ‹case›, which can be meticulously monitored and studied so as to record the genesis of a crime. In this paper, Büchner’s unsettling play is analysed in detail as one of the great anticipatory literary documents of the 19th century, ex- ploring the idea of predictive psychiatry and the quest for genetic pre- dispositions: a primal scene as it were of the nature-nurture debate as it unfolds from predictive criminology up to behavioural genomics.

n this article the author develops a critique of reductionism in biological sciences from three different points of view. The first is related to the problem of reduction in the context of scientific theories. More specifically, reduction deals with a special form of intertheoretic relationship between molecular biology and the rest of biology. The second meaning of reductionism has to do with the significance of its genetic outfit for the ontogeny of an organism, i.e. its development from zygote to its (...) final or adult structure and function. Third, closely related to this more biological topic are questions about the anthropological consequences of the application of reductionistic methodologies for the explanation and evaluation of human behaviour.

This is an introductory article on sociobiology, particularly its relationship to eugenics. Sociobiology developed in the 1960s as a field within evolutionary biology to explain human social traits and behaviours. Although sociobiology has few direct connections to eugenics, it shares eugenics’ optimistic enthusiasm for extending biological science into the human domain, often with reckless sensationalism. Sociobiology's critics have argued that sociobiology also propagates a kind of genetic determinism and represents the zealous misapplication of science beyond its proper reach that characterized (...) the eugenics movement. More recently, evolutionary psychology represents a sophistication of sociobiology that attends to the mind as the "missing link" between evolution and behaviour (Cosmides and Tooby 1992, Pinker 1997).

Abstract The quasispecies theory is a helpful concept in the explanation of RNA virus evolution and behaviour, with a relevant impact on methods used to fight viral diseases. It has undergone some adaptations to integrate new empirical data, especially the non-deterministic nature of mutagenesis, and the variety of behavioural motifs in cooperation, competition, communication, innovation, integration, and exaptation. Also, the consortial structure of quasispecies with complementary roles of memory genomes of minority populations better fits the empirical data than did (...) the original concept of a master sequence and its mutant spectra. The high productivity of quasispecies variants generates unique sequences that never existed before and will never exist again. In the present essay, we underline that such sequences represent really new ontological entities, not just error copies of previous ones. Their primary unique property, the incredible variant production, is suggested here as quasispecies productivity, which replaces the error-replication narrative to better fit into a new relationship between mankind and living nature in the twenty-first century.

Cooperation is rife in the microbial world, yet our best current theories of the evolution of cooperation were developed with multicellular animals in mind. Hamilton’s theory of inclusive fitness is an important case in point: applying the theory in a microbial setting is far from straightforward, as social evolution in microbes has a number of distinctive features that the theory was never intended to capture. In this article, I focus on the conceptual challenges posed by the project of extending Hamilton’s (...) theory to accommodate the effects of gene mobility. I begin by outlining the basics of the theory of inclusive fitness, emphasizing the role that the concept of relatedness is intended to play. I then provide a brief history of this concept, showing how, over the past fifty years, it has departed from the intuitive notion of genealogical kinship to encompass a range of generalized measures of genetic similarity. I proceed to argue that gene mobility forces a further revision of the concept. The reason in short is that, when the genes implicated in producing social behaviour are mobile, we cannot talk of an organism’s genotype simpliciter; we can talk only of an organism’s genotype at a particular stage in its life cycle. We must therefore ask: with respect to which stage(s) in the life cycle should relatedness be evaluated? For instance: is it genetic similarity at the time of social interaction that matters to the evolution of social behaviour, or is it genetic similarity at the time of reproduction? I argue that, strictly speaking, it is neither of these: what really matters to the evolution of social behaviour is diachronic genetic similarity between the producers of fitness benefits at the time they produce them and the recipients of those benefits at the end of their life-cycle. I close by discussing the implications of this result. The main payoff is that it makes room for a possible new mechanism for the evolution of altruism in microbes that does not require correlated interaction among bearers of the genes for altruism. The importance of this mechanism in nature remains an open empirical question. (shrink)

The vision of legendary criminologist Cesare Lombroso to use scientific theories of individual causes of crime as a basis for screening and prevention programmes targeting individuals at risk for future criminal behaviour has resurfaced, following advances in genetics, neuroscience and psychiatric epidemiology. This article analyses this idea and maps its ethical implications from a public health ethical standpoint. Twenty-seven variants of the new Lombrosian vision of forensic screening and prevention are distinguished, and some scientific and technical limitations are noted. (...) Some lures, biases and structural factors, making the application of the Lombrosian idea likely in spite of weak evidence are pointed out and noted as a specific type of ethical aspect. Many classic and complex ethical challenges for health screening programmes are shown to apply to the identified variants and the choice between them, albeit with peculiar and often provoking variations. These variations are shown to actualize an underlying theoretical conundrum in need of further study, pertaining to the relationship between public health ethics and the ethics and values of criminal law policy.

As opposed to a ‘one size fits all’ approach, precision medicine uses relevant biological, medical, behavioural and environmental information about a person to further personalize their healthcare. This could mean better prediction of someone’s disease risk and more effective diagnosis and treatment if they have a condition. Big data allows for far more precision and tailoring than was ever before possible by linking together diverse datasets to reveal hitherto-unknown correlations and causal pathways. But it also raises ethical issues relating (...) to the balancing of interests, viability of anonymization, familial and group implications, as well as genetic discrimination. This article analyses these issues in light of the values of public benefit, justice, harm minimization, transparency, engagement and reflexivity and applies the deliberative balancing approach found in theEthical Framework for Big Data in Health and Research to a case study on clinical genomic data sharing. Please refer to that article for an explanation of how this framework is to be used, including a full explanation of the key values involved and the balancing approach used in the case study at the end. Our discussion is meant to be of use to those involved in the practice as well as governance and oversight of precision medicine to address ethical concerns that arise in a coherent and systematic manner.

Psychopaths routinely disregard social norms by engaging in selfish, antisocial, often violent behavior. Commonly characterized as mentally disordered, recent evidence suggests that psychopaths are executing a well-functioning, if unscrupulous strategy that historically increased reproductive success at the expense of others. Natural selection ought to have favored strategies that spared close kin from harm, however, because actions affecting the fitness of genetic relatives contribute to an individual’s inclusive fitness. Conversely, there is evidence that mental disorders can disrupt psychological mechanisms designed to (...) protect relatives. Thus, mental disorder and adaptation accounts of psychopathy generate opposing hypotheses: psychopathy should be associated with an increase in the victimization of kin in the former account but not in the latter. Contrary to the mental disorder hypothesis, we show here in a sample of 289 violent offenders that variation in psychopathy predicts a decrease in the genetic relatedness of victims to offenders; that is, psychopathy predicts an increased likelihood of harming non-relatives. Because nepotistic inhibition in violence may be caused by dispersal or kin discrimination, we examined the effects of psychopathy on (1) the dispersal of offenders and their kin and (2) sexual assault frequency (as a window on kin discrimination). Although psychopathy was negatively associated with coresidence with kin and positively associated with the commission of sexual assault, it remained negatively associated with the genetic relatedness of victims to offenders after removing cases of offenders who had coresided with kin and cases of sexual assault from the analyses. These results stand in contrast to models positing psychopathy as a pathology, and provide support for the hypothesis that psychopathy reflects an evolutionary strategy largely favoring the exploitation of non-relatives.

In my view all behavior is an expression of our evolved psychology and so intimately connected to religion, morals and ethics, if one knows how to look at them. -/- Many will find it strange that I spend little time discussing the topics common to most discussions of religion, but in my view it is essential to first understand the generalities of behavior and this necessitates a good understanding of biology and psychology which are mostly noticeable by their absence in (...) works on religion, politics, history, morals and ethics, etc. In my view most such efforts have no grasp at all of the operation of System 2, the slow cortical functions of the brain which can be equated to linguistic behavior or the mind, and which I call the Descriptive Psychology of Higher Order Thought and which I regard as the province of philosophy in the narrow sense. -/- It is my contention that the table of intentionality (rationality, mind, thought, language, personality etc.) that features prominently here describes more or less accurately, or at least serves as an heuristic for, how we think and behave, and so it encompasses not merely philosophy and psychology, but everything else (religion, history, literature, mathematics, politics etc.). Note especially that intentionality and rationality as I (along with Searle, Wittgenstein and others) view it, includes both conscious deliberative System 2 and unconscious automated System 1 actions or reflexes. -/- This collection of articles was written over the last 10 years and revised to bring them up to date (2019). All the articles are about human behavior (as are all articles by anyone about anything), and so about the limitations of having a recent monkey ancestry (8 million years or much less depending on viewpoint) and manifest words and deeds within the framework of our innate psychology as presented in the table of intentionality. As famous evolutionist Richard Leakey says, it is critical to keep in mind not that we evolved from apes, but that in every important way, we are apes. If everyone was given a real understanding of this (i.e., of human ecology and psychology to actually give them some control over themselves), maybe civilization would have a chance. As things are however the leaders of society have no more grasp of things than their constituents and so collapse into anarchy is inevitable is spite of the near universal views that religion, politics or technology can save us. See my Suicidal Utopian Delusions in the 21st Century 5th ed (2019), for a detailed exposition of this view. -/- It is critical to understand why we behave as we do and so I start with a brief review of the logical structure of rationality, which provides some heuristics for the description of language (mind, rationality, personality) and gives some suggestions as to how this relates to the evolution of social behavior. This centers around the two writers I have found the most important in this regard, Ludwig Wittgenstein and John Searle, whose ideas I combine and extend within the dual system (two systems of thought) framework that has proven so useful in recent thinking and reasoning research. As I note, there is in my view essentially complete overlap between philosophy, in the strict sense of the enduring questions that concern the academic discipline, and the descriptive psychology of higher order thought (behavior). Once one has grasped Wittgenstein’s insight that there is only the issue of how the language game is to be played, one determines the Conditions of Satisfaction (what makes a statement true or satisfied etc.) and that is the end of the discussion. No neurophysiology, no metaphysics, no postmodernism, no theology. -/- Along with many, I see it as the basic religious or moral issue of our times that America and the world are in the process of collapse from excessive population growth, most of it for the last century, and now all of it, due to 3rd world people. Consumption of resources and the addition of 3 billion more ca. 2100 will collapse industrial civilization and bring about starvation, disease, violence and war on a staggering scale. The earth loses at least 1% of its topsoil every year, so as it nears 2100, most of its food growing capacity will be gone. Billions will die and nuclear war is all but certain. In America, this is being hugely accelerated by massive immigration and immigrant reproduction, combined with abuses made possible by democracy. Depraved human nature inexorably turns the dream of democracy and diversity into a nightmare of crime and poverty. China will continue to overwhelm America and the world, as long as it maintains the dictatorship which limits selfishness and permits long term planning. The root cause of collapse is the inability of our innate psychology to adapt to the modern world, which leads people to treat unrelated persons as though they had common interests (which I suggest may be regarded as an unrecognized -- but the commonest and most serious-- psychological problem -- Inclusive Fitness Disorder). This, plus ignorance of basic biology and psychology, leads to the social engineering delusions of the partially educated who control democratic societies. Few understand that if you help one person you harm someone else—there is no free lunch and every single item anyone consumes destroys the earth beyond repair. Consequently, social policies everywhere are unsustainable and one by one all societies without stringent controls on selfishness will collapse into anarchy or dictatorship. Without dramatic and immediate changes, there is no hope for preventing the collapse of America, or any country that follows a democratic system, especially now that the Neomarxist Third World Supremacists are taking control of the USA and other Western Democracies, and helping the Seven Sociopaths who run China to succeed in their plan to eliminate peace and freedom and religion worldwide. Hence my concluding essays. Of course, it is an easily defensible point of view that Artificial Intelligence (aka Artificial Stupidity or Artificial Sociopathy) researchers are even more evil than the Democrats and the CCP, and I make brief comments on this as well. -/- Several articles touch on The One Big Happy Family Delusion, i.e., that we are genetically selected for cooperation with everyone, and that the euphonious ideals of Democracy, Diversity, Equality and Religion will lead us into utopia, if we just manage things correctly (the possibility of politics). Again, the No Free Lunch Principle ought to warn us it cannot be true, and we see throughout history and all over the contemporary world, that without strict controls, selfishness and stupidity gain the upper hand and soon destroy any nation that embraces these delusions. In addition, the monkey mind steeply discounts the future, and so we cooperate in selling our descendant’s heritage for temporary comforts, greatly exacerbating the problems. -/- I describe versions of this delusion (i.e., that we are basically ‘friendly’ if just given a chance) as it appears in some recent books on sociology/biology/economics. Even Sapolsky’s otherwise excellent “Behave” (2017) embraces leftist politics and group selection and gives space to a discussion of whether humans are innately violent. I end with two essays on the great tragedy playing out in America and the world, which can be seen as a direct result of our evolved psychology manifested as the inexorable machinations of System 1. Our psychology, eminently adaptive and eugenic on the plains of Africa from ca. 6 million years ago, when we split from chimpanzees, to ca. 50,000 years ago, when many of our ancestors left Africa (i.e., in the EEA or Environment of Evolutionary Adaptation), is now maladaptive and dysgenic and the source of our Suicidal Utopian Delusions. So, like all discussions of behavior (theology, philosophy, psychology, sociology, biology, anthropology, politics, law, literature, history, economics, soccer strategies, business meetings, etc.), this book is about evolutionary strategies, selfish genes and inclusive fitness (kin selection, natural selection), though of course few grasp this, regardless of whether they are academics or peasants, atheists or fundamentalists.

If each of the subtypes of autism is defined simply as constituted by a set of symptoms, then the criteria for its observation are straightforward, although, of course, some of those symptoms themselves might be hard to observe definitively. Compare with telling whether or not someone is bleeding: while it might be hard to tell if someone is bleeding internally, we know what it takes to find out, and when we have the right access and instruments we can settle the (...) issue. But matters are not so simple for the autism subtypes. For one thing, how do we settle which symptoms to group together under one heading? One key difference between “autism disorder” and “Asperger’s disorder” is that the former exhibit language delays (sometimes extreme), whereas the latter do not. But is that a sign of genuinely distinct conditions or is that an artifact of the distinct groups of subjects that Leo Kanner and Hans Asperger worked with? And in general, although there are certainly types of behavior that are taken to be indicative of autism, none by itself is taken by diagnosticians to be either necessary or sufficient for a definitive diagnosis for any of the autism subtypes. What is the diagnostician to do? This is not merely an academic issue, as many parents can attest. Are we in a situation, then, that each practitioner has his or her own “pet” signs that are the “real keys” to the diagnosis? That would suggest that the term “autistic” might meet the fate of the outdated term “neurotic,” which turned out to be a pseudo-scientific term for an inexact clumping together of unrelated phenomena. The assumption amongst specialists seems to be that we will reach the point with "autism" that we have with "water": there will be a root essence to autism whose presence or absence settles a diagnosis. If that is to be the case, however, we have to settle the level of application of the concept. Does the term apply to people who exhibit particular behaviors? Or is it possible to exhibit “autistic” behaviors without actually being autistic, because autism is instead a particular feature of the mind (as, for example, in Baron-Cohen’s “impaired theory of mind module” theory, discussed below) which usually but not necessarily has behavioral effects? Or is autism located instead in the brain, perhaps in damage to key areas, which in turn would typically have an effect on modules of the mind? Or perhaps autism is located in genetics or biology, so that some people with damage to the brain caused by accidents so that they exhibit autistic symptoms would not actually be autistic. Conversely, supposing one had an “autistic brain” but showed none of (or not a sufficient number of) the symptoms, would one not be autistic? The assumption is that the genotypes and phenotypes will line up neatly, but if they do not, what happens to the concept “autistic?” (There is an analogy in the philosophy of sex and gender: androgen insensitive individuals tend to self-identify as female and have outward female traits, but have XY chromosomes—should we go with chromosomes or self-identity in assigning sex category?) Finally, the implications for these complications for diagnosis and categorization, with the attendant social and medical implications is discussed. The typical assumption of the medical profession is that autism cannot be “cured.” That assumes that autism is not simply the symptoms. However, at the same time, the tests used to diagnose ASDs work simply from the symptoms (for example, Baron-Cohen’s Sally/Anne test, which ASD children of a certain age almost all fail, but which practically no ASD adult fails). This implies an inherent confusion over the status of the concept. I conclude that attempts to make sense of some true or accurate summary of what it is to be autistic (such as one would find in the DSM) are almost certainly misguided and will vanish into history along with “neurotic.” But as with racial terms, which are similarly shifting and perverse, the term has already passed into the public sphere and will have a lasting and dangerous influence beyond its short scientific shelf-life.

Neuroscience is a laboratory-based science that spans multiple levels of analysis from molecular genetics to behavior. At every level of analysis experiments are designed in order to answer empirical questions about phenomena of interest. Understanding the nature and structure of experimentation in neuroscience is fundamental for assessing the quality of the evidence produced by such experiments and the kinds of claims that are warranted by the data. This article provides a general conceptual framework for thinking about evidence and experimentation (...) in neuroscience with a particular focus on two research areas: cognitive neuroscience and cognitive neurobiology.

Universal social institutions, such as marriage, commons management and property, have emerged independently in radically different cultures. This requires explanation. As Boyer and Petersen point out ‘in a purely localist framework would have to constitute massively improbable coincidences’ . According to Boyer and Petersen, those institutions emerged naturally out of genetically wired behavioural dispositions, such as marriage out of mating strategies and borders out of territorial behaviour. While I agree with Boyer and Petersen that ‘unnatural’ institutions cannot thrive, this (...) one-sided explanation of universal social institutions in terms of genetic human nature is unsatisfactory. Drawing on the literature on multi-level selection and gene-culture coevolution, I argue that universal social institutions are first and foremost the products of cultural selection. They occupy fitness peaks in the landscape of cultural possibilities, much in the same way that biological adaptations occupy fitness peaks in the landscape of biological possibilities. To show this, I use game-theory. By modelling the domains of social interaction in which marriage, commons management, and property emerged as Prisoner’s dilemma situations, it becomes clear how an institutional framework allows the group to move to an interactive equilibrium with a larger payoff. Institutions do so by incentivising all parties to adopt a cooperative strategy. They are culturally selected ways of optimising genetically constrained domains of human social interaction. (shrink)

Representations are not only used in our folk-psychological explanations of behaviour, but are also fruitfully postulated, for example, in cognitive science. The mainstream view in cognitive science maintains that our mind is a representational system. This popular view requires an understanding of the nature of the entities they are postulating. Teleosemantic theories face this challenge, unpacking the normativity in the relation of representation by appealing to the teleological function of the representing state. It has been argued that, if intentionality is (...) to be explained in teleological terms, then the function of a state cannot depend on its phylogenetical history, given the metaphysical possibility of a duplicate of an intentional being that lacks an evolutionary history. In this paper, I present a method to produce, according to our current knowledge in genetic engineering, human-like individuals who are not the product of natural selection in the required sense. This variation will be used to shed light on the main replies that have been offered in the literature to the Swampman thought experiment. I argue that these replies are not satisfactory: representations should better not depend on natural selection. I conclude that a non-etiological notion of function is to be preferred for characterizing the relation of representation. (shrink)

Species concepts aim to define the species category. Many of these rely on defining species in terms of natural lineages and groupings. A dominant gene-centred metaconception has shaped notions of what constitutes both a natural lineage and a natural grouping. I suggest that relying on this metaconception provides an incomplete understanding of what constitute natural lineages and groupings. If we take seriously the role of epigenetic, behavioural, cultural, and ecological inheritance systems, rather than exclusively genetic inheritance, a broader notion (...) of what constitutes a natural grouping or lineage may be required. I conclude by outlining an alternative metaconception that is a de-centred metaschema for species. (shrink)

Advocates of moral enhancement through pharmacological, genetic, or other direct interventions sometimes explicitly argue, or assume without argument, that traditional moral education and development is insufficient to bring about moral enhancement. Traditional moral education grounded in a Kohlbergian theory of moral development is indeed unsuitable for that task; however, the psychology of moral development and education has come a long way since then. Recent studies support the view that moral cognition is a higher-order process, unified at a functional level, and (...) that a specific moral faculty does not exist. It is more likely that moral cognition involves a number of different mechanisms, each connected to other cognitive and affective processes. Taking this evidence into account, we propose a novel, empirically informed approach to moral development and education, in children and adults, which is based on a cognitive-affective approach to moral dispositions. This is an interpretative approach that derives from the cognitive-affective personality system (Mischel and Shoda, 1995). This conception individuates moral dispositions by reference to the cognitive and affective processes that realise them. Conceived of in this way, moral dispositions influence an agent's behaviour when they interact with situational factors, such as mood or social context. Understanding moral dispositions in this way lays the groundwork for proposing a range of indirect methods of moral enhancement, techniques that promise similar results as direct interventions whilst posing fewer risks.

Relying on (...) the discoveries about embryogenesis, and also with the use of information theory, Ruyer proposed an interpretation of the main unifying concepts of mechanistic cybernetics. -/- Cet ouvrage propose une étude fouillée d'un des principaux axes de réflexion du philosophe des sciences et de la nature français Raymond Ruyer (1902–1987) : la cybernétique. Après avoir proposé une philosophie structuraliste, Ruyer la modifia à la lumière des découvertes de l'embryogenèse, puis il proposa une interprétation des concepts unificateurs de la cybernétique mécaniste. Réfléchissant sur cette dernière et sur la théorie de l'information, en particulier sur l'origine de l'information, il défendit que cette cybernétique n'était qu'une lecture inversée de la vraie cybernétique, qui nous donnerait de lire dans l'expérience même les traces du pouvoir morphogénétique, appréhendé comme un champ axiologique. Dans un texte résumant son propre parcours, Ruyer affirma finalement que la critique de la théorie de l'information « peut donner […] l'espoir d'aboutir à quelque chose comme une nouvelle théologie. » Les idées directrices de Ruyer sont tout particulièrement contextualisées ici à partir de la question du développement des formes en biologie, et de celles de la génétique, de la genèse stochastique de l'ordre, et de l'identification mentale ou physique de l'information. Il se termine en départageant ce qui est théologique et axiologique dans ce projet de métaphysique qui, bien que resté inachevé, n'en représente pas moins le plus impressionnant conçu en France au siècle dernier. – This book offers an in-depth study of one of the main axes in the reflection of French philosopher of science and nature Raymond Ruyer. In a text summarising his own development, Ruyer stated about the philosophical critique of information theory that it "is what can give the most long-lasting hope of getting to something like a new theology." After propounding a structuralist philosophy, and distinguishing between form and structure, to then modify it in the light of discoveries in embryogenesis, Ruyer offered a re-evaluation of the unifying concepts of mechanistic cybernetics. Thinking about it and about information theory, he defended the idea that this cybernetics was in reality an inverted reading of the real one, which would allow us to read in experience itself traces of the morphogenetic power, apprehended as the axiological field. On some transversal points, the development of forms in biology and genetics, the stochastic genesis of order, the identification of information with either psychological and mental, or physical reality, behaviour, and the access to meaning, this work exposes the main ideas of Ruyer while situating them in the context of the breadth of others' contributions. It ends by determining what is theological and axiological in this project for a metaphysics which, although unfinished, is nevertheless the most impressive effort done in France in the last century. – Available on i6doc dot com (ISBN 978-2-930517-56-8 ; pdf 978-2-930517-57-5).

In 1926, Haldane published an essay titled 'On Being the Right Size' in which he argued that the structure, function, and behavior of an organism are strongly conditioned by the physical forces that exert the greatest impact at the scale at which it exists. This chapter puts Haldane’s insight to work in the context of contemporary cell and molecular biology. Owing to their minuscule size, cells and molecules are subject to very different forces than macroscopic organisms. In a sense, macroscopic (...) and microscopic entities inhabit different “worlds”: the former is ruled by gravity and inertia, whereas the latter is governed by Brownian motion. One implication is that we should be extremely skeptical of models and analogies that seek to explain properties of microscopic entities by appealing to properties of macroscopic ones. Unfortunately, this is precisely what the appeal to engineering metaphors in molecular biology attempts to do. Molecular biologists routinely resort to such metaphors because they are familiar and intuitively intelligible. But if our machines were the size of molecules it would be impossible for them to function the way they do. It follows that we should avoid distorting biological reality by construing it in engineering terms. In this chapter I examine four key metaphors in molecular biology – “genetic program,” “cellular circuitry,” “molecular machine,” and “molecular motor” – and I argue that their deficiencies derive from their neglect of scale. I also try to explain why many biologists today appear to have forgotten the importance of scale that Haldane drew attention to in his essay. I suggest that the reason has to do with the influence of Schrödinger’s argument in 'What is Life?' regarding the stability of the gene. (shrink)

How do conventions of communication emerge? How do sounds or gestures take on a semantic meaning, and how do pragmatic conventions emerge regarding the passing of adequate, reliable, and relevant information? My colleagues and I have attempted in earlier work to extend spatialized game theory to questions of semantics. Agent-based simulations indicate that simple signaling systems emerge fairly naturally on the basis of individual information maximization in environments of wandering food sources and predators. Simple signaling emerges by means of any (...) of various forms of updating on the behavior of immediate neighbors: imitation, localized genetic algorithms, and partial training in neural nets. Here the goal is to apply similar techniques to questions of pragmatics. The motivating idea is the same: the idea that important aspects of pragmatics, like important aspects of semantics, may fall out as a natural results of information maximization in informational networks. The attempt below is to simulate fundamental elements of the Gricean picture: in particular, to show within networks of very simple agents the emergence of behavior in accord with the Gricean maxims. What these simulations suggest is that important features of pragmatics, like important aspects of semantics, don't have to be added in a theory of informational networks. They come for free.

Heyes presents a compelling account of how cultural evolutionary processes shape and create “rules,” or norms, of social behavior. She suggested that normativity depends on implicit, genetically inherited, domain-general processes and explicit, culturally inherited, domain-specific processes. Her approach challenges the nativist point of view and provides supporting evidence that shows how social interactions are responsible for creating mental processes that assist in understanding and behaving according to rules or norms. We agree. In our commentary, we suggest that it is not (...) only that mental processes for grasping norms are recreated in each generation but also that social interactions shape the kinds of social groups that are recognized (for a more extensive discussion, see Kish Bar-On & Lamm, 2023). We highlight evidence showing that accounts of norm psychology thus require a richer notion of human groups. (shrink)

What is it for a sound or gesture to have a meaning, and how does it come to have one? In this paper, a range of simulations are used to extend the tradition of theories of meaning as use. The authors work throughout with large spatialized arrays of sessile individuals in an environment of wandering food sources and predators. Individuals gain points by feeding and lose points when they are hit by a predator and are not hiding. They can also (...) make sounds heard by immediate neighbours in the array, and can respond to sounds from immediate neighbours. No inherent meaning for these sounds is built into the simulation; under what circumstances they are sent, if any, and what the response to them is, if any, vary initially with the strategies randomized across the array. These sounds do take on a specific function for communities of individuals, however, with any of three forms of strategy change: direct imitation of strategies of successful neighbours, a localized genetic algorithm in which strategies are ‘crossed’ with those of successful neighbours, and neural net training on the behaviour of successful neighbours. Starting from an array randomized across a large number of strategies, and using any of these modes of strategy change, communities of ‘communicators’ emerge. Within these evolving communities the sounds heard from immediate neighbours, initially arbitrary across the array, come to be used for very specific communicative functions. ‘Communicators’ make a particular sound on feeding and respond to that same sound from neighbours by opening their mouths; they make a different sound when hit with a predator and respond to that sound by hiding. Robustly and persistently, even in simple computer models of communities of self-interested agents, something suggestively like signalling emerges and spreads. Keywords: meaning, communication, genetic algorithms, neural networks. (shrink)

The book on "Science and the image of man" pursues different pathways by way of which science contributes to the understanding of human beings as a species: the scope and limits of human cognition are revealed by the history and the mental structure of science in a more precise manner than by any other cultural effort. Insights into the evolution and function of the human brain elucidate the origin and the range of general human capabilities, such as language, self-representation and (...) strategic thought. These capabilities are the products of biological evolution as well as preconditions of cultural development, which is based on traditions rather than on genetic inheritance. At the metatheoretical level, modern science reveals its own intrinsic limitations and is open to different cultural and philosophical interpretations. Human consciousness is a product of evolution of the human brain, and yet it may not be possible to decode the mind-brain relation fully by finite procedures. One of the specifically human capabilities is cognition-based empathy; it may have evolved in conjunction with strategic thought, because it facilitates the prediction of the behaviour of others, but it also motivates altruistic behaviour. Stereotyped controversies between sociologists and social biologists on human ethics appear somewhat outdated; there is a biological basis in humans not only for egoism but, to a limited extent, also for cooperativity and solidarity. Ethical demands should respect the biological conditions of the human species. They imply that cooperativeness is a real but limited resource. It requires activation, but excessive moralism is counterproductive. -/- -/-. (shrink)

Most molecular biological concepts derive from physical chemical assumptions about the genetic code that are basically more than 40 years old. Additionally, systems biology, another quantitative approach, investigates the sum of interrelations to obtain a more holistic picture of nucleotide sequence order. Recent empirical data on genetic code compositions and rearrangements by mobile genetic elements and non-coding RNAs, together with results of virus research and their role in evolution, does not really fit into these concepts and compel a re-examination. In (...) this review we try to find an alternate hypothesis. It seems plausible now that if we look at the abundance of regulatory RNAs and persistent viruses in host genomes, we will find more and more evidence that the key players that edit the genetic codes of host genomes are consortia of RNA agents and viruses that drive evolutionary novelty and regulation of cellular processes in all steps of development. This agent-based approach may lead to a qualitative RNA sociology that investigates and identifies relevant behavioural motifs of cooperative RNA consortia. In addition to molecular biological perspectives this may lead to a better understanding of genetic code evolution and dynamics. (shrink)

Humans often behave altruistically towards strangers with no chance of reciprocation. From an evolutionary perspective, this is puzzling. The evolution of altruistic cooperative behavior—in which an organism’s action reduces its fitness and increases the fitness of another organism —only makes sense when it is directed at genetically related organisms or when one can expect the favor to be returned. Therefore, evolutionary theorists such as Sober and Wilson have argued that we should revise Neo-Darwininian evolutionary theory. They argue that human altruism (...) evolved through group selection in which groups of altruists were naturally selected because they had a comparative advantage over other groups. Wilson and Sober’s hypothesis attracted followers but is rejected by most of their peers. The heated debate between advocates and critics of group selection often suffers from a lack of conceptual clarity. In response, I set out to clearly distinguish ‘genetic’ from ‘cultural’ group selection and argue that the latter does not face the potentially debilitating problems plaguing the former. I defend the claim that human altruistic dispositions evolved through cultural group selection and gene-culture coevolution and offer empirical evidence in support. I also argue that actual altruistic behavior often goes beyond the kind of behavior humans have evolved to display. Conscious and voluntary reasoning processes, I show, have an important role in altruistic behavior. This is often overlooked in the scientific literature on human altruism. (shrink)

Political philosophers often draw their conclusions on how political systems ought to be by first investigating human nature and then proposing recommendations extrapolating from those investigations. They attempt to do this by creating a hypothetical ‘state of nature’ where human beings would be unaffected by social, political, and cultural paradigms and can act freely in pursuit of their instincts, thereby revealing their true nature. English philosopher Thomas Hobbes followed this method of investigation and found that human beings are naturally violent, (...) individualistic, warlike and therefore concluded that political theory ought to be as such to prevent human beings from acting out their baser impulses through draconian authoritative measures when necessary. In this paper, I challenge Hobbes’s claim on human nature by citing contemporary research on cognitive sciences which demonstrates that human beings have a natural predisposition to believe in supernatural agency (God/s) and therefore in the state of nature must behave in such a way as contemporary psychologists discovered investigating the effect of religiosity on human beings such as increased cooperation, selfless behavior towards genetically unrelated strangers, reduced crime rate deterred by supernatural punishment, etcetera. I argue that if we take into account the human propensity to believe in the supernatural agency then the state of nature hypothesized by Hobbes would need to be modified and therefore so would his political theory. Given the integration of cognitive science of religion into the state of nature, I conclude that the ideal political system must be centered around religion.

A network of gene regulation organized in a hierarchical and combinatorial manner is crucially involved in the development of the neural network, and has to be considered one of the main substrates of genetic change in its evolution. Though qualitative features may emerge by way of the accumulation of rather unspecific quantitative changes, it is reasonable to assume that at least in some cases specific combinations of regulatory parts of the genome initiated new directions of evolution, leading to novel capabilities (...) of the brain. These notions are applied, in this paper, to the evolution of the capability of cognition-based human empa­thy. It is suggested that it has evolved as a secondary effect of the evolution of strategic thought. Development of strategies depends on abstract representations of one’s own pos­sible future states in one’s own brain to allow assessment of their emotional desirability, but also on the representation and emotional evaluation of possible states of others, allowing anticipation of their behaviour. This is best achieved if representations of others are con­nected to one’s own emotional centres in a manner similar to self-representations. For this reason, the evolution of the human brain is assumed to have established representations with such linkages. No group selection is involved, because the quality of strategic thought affects the fitness of the individual. A secondary effect of this linkage is that both the actual states and the future perspectives of others elicit vicarious emotions, which may contribute to the motivations of altruistic behaviour.

Parts of the genome of a single individual can have conflicting interests, depending on which parent they were inherited from. One mechanism by which these conflicts are expressed in some taxa, including mammals, is genomic imprinting, which modulates the level of expression of some genes depending on their parent of origin. Imprinted gene expression is known to affect body size, brain size, and the relative development of various tissues in mammals. A high fraction of imprinted gene expression occurs in the (...) brain. Biologists including Hamilton, Trivers and Haig have proposed that this may explain some intrapersonal conflict in humans. This speculation amounts to an inference from conflict within the genome to conflict within the brain or mind. This is a provocative proposal, which deserves serious attention. In this paper I assess aspects of Haig’s version of the proposal. I argue, first, that the notion that intragenomic conflict predicts personal inconsistency should be rejected. Second, while it is unlikely that it credibly predicts sub-personal agents representing conflicting genetic interests, it is plausible that it predicts that the division of cognitive labour could be exploited to turn sub-systems into proxies for conflicting interests.

If humans have an evolved moral psychology, then we should not expect it to function in an identical way between individuals. Instead, we should expect a diversity in the function of our moral psychology between individuals that varies along genetic lines, and a corresponding diversity of moral attitudes and moral judgements that emerge from it. This is because there was no one psychological type that would reliably produce adaptive social behaviour in the highly heterogeneous environments in which our minds evolved. (...) As such, there was no single psychological type towards which evolution could gravitate. Instead we evolved a stable polymorphism of psychological types, maintained by frequency-dependent selection, each predisposed towards particular social and moral attitudes and behaviours. This can help explain the existence of moral diversity, particularly intra-cultural moral diversity, and seemingly intractable moral disagreement. (shrink)

Humans are uncontroversially better than other species at learning from their peers. A key example of this is imitation, the ability to reproduce both the means and ends of others’ behaviours. Imitation is critical to the acquisition of a number of uniquely human cultural and cognitive traits. However, while authors largely agree on the importance of imitation, they disagree about the origins of imitation in humans. Some argue that imitation is an adaptation, connected to the ‘Mirror Neuron System’ that evolved (...) to facilitate action understanding and the learning of social behaviours. Others argue that imitation is a cultural practice learned in childhood, and that there is no evidence that it evolved genetically. We offer a third alternative that is consistent with both data that the human brain is optimised for imitation, and consistent with its being substantially learned. We hypothesise that at some point in human history humans underwent natural selection for two imitation-relevant abilities – specifically, (i) the tendency to be more attentive to our peers, and (ii) fine motor skill in the manual and oro-facial domains. These changes enabled us to excel at both learning to imitate, and learning by imitating. (shrink)

Tanto como el 50% de todas las concepciones, o unos 100 millones/año, terminan en abortos espontáneos tempranos, casi todos sin que la madre sea consciente. Este sacrificio natural de genes defectuosos impulsa la evolución, nos mantiene relativamente genéticamente sólidas y hace posible la sociedad. La disgenesia es suficiente para destruir la civilización pero sobrepoblación se do primero. -/- Aquellos que deseen un marco completo hasta la fecha para el comportamiento humano de la moderna Dos Sistemas Punto de Vista puede consultar mi libro 'La estructura lógica de la filosofía, la psicología, la mente y lenguaje En Ludwig Wittgenstein y John Searle ' 2Nd Ed (2019).

Environmental variability has been proposed as an important mechanism in behavioral psychology, in ecology and evolution, and in cultural anthropology. Here we demonstrate its importance in simulational studies as well. In earlier work we have shown the emergence of communication in a spatialized environment of wandering food sources and predators, using a variety of mechanisms for strategy change: imitation (Grim, Kokalis, Tafti & Kilb 2000), localized genetic algorithm (Grim, Kokalis, Tafti & Kilb 2001), and partial training of neural nets on (...) the behavior of successful neighbors (Grim, St. Denis & Kokalis 2002). Here we focus on environmental variability, comparing results for all of these mechanisms in a range of different environments: (a) environments with constant resources, (b) environments with random resources around the same mean, and (c) sine-wave variable environments with cycles of ‘boom and bust’. Communication, it turns out, is strongly favored by environmental variability on the pattern of ‘boom and bust.'. (shrink)
