The idea of genetic assimilation, that environmentally induced phenotypes may become genetically fixed and no longer require the original environmental stimulus, has had varied success through time in evolutionary biology research. Proposed by Waddington in the 1940s, it became an area of active empirical research mostly thanks to the efforts of its inventor and his collaborators. It was then attacked as of minor importance during the ‘‘hardening’’ of the neo-Darwinian synthesis and was relegated to a secondary role for (...) decades. Recently, several papers have appeared, mostly independently of each other, to explore the likelihood of genetic assimilation as a biological phenomenon and its potential importance to our understanding of evolution. In this article we briefly trace the history of the concept and then discuss theoretical models that have newly employed genetic assimilation in a variety of contexts. We propose a typical scenario of evolution of genetic assimilation via an intermediate stage of phenotypic plasticity and present potential examples of the same. We also discuss a conceptual map of current and future lines of research aimed at exploring the actual relevance of genetic assimilation for evolutionary biology. (shrink)

In addition to considerable debate in the recent evolutionary literature about the limits of the Modern Synthesis of the 1930s and 1940s, there has also been theoretical and empirical interest in a variety of new and not so new concepts such as phenotypic plasticity, genetic assimilation and phenotypic accommodation. Here we consider examples of the arguments and counter- arguments that have shaped this discussion. We suggest that much of the controversy hinges on several misunderstandings, including unwarranted fears of (...) a general attempt at overthrowing the Modern Synthesis paradigm, and some fundamental conceptual confusion about the proper roles of phenotypic plasticity and natural selection within evolutionary theory.

The so-called “Baldwin Effect” has been studied for years in the fields of Artificial Life, Cognitive Science, and Evolutionary Theory across disciplines. This idea is often conflated with genetic assimilation, and has raised controversy in trans-disciplinary scientific discourse due to the many interpretations it has. This paper revisits the “Baldwin Effect” in Baldwin’s original spirit from a joint historical, theoretical and experimental approach. Social Heredity – the inheritance of cultural knowledge via non-genetic means in Baldwin’s term – (...) is also taken into consideration. I shall argue that the Baldwin Effect can occur via social heredity without necessity for genetic assimilation. Computational experiments are carried out to show that when social heredity is permitted with high fidelity, there is no need for the assimilation of acquired characteristics; instead the Baldwin Effect occurs as promoting more plasticity to facilitate future intelligence. The role of mind and intelligence in evolution and its implications in an extended synthesis of evolution are briefly discussed. (shrink)

Back in 1942, C.H. Waddington proposed a new mechanism of evolutionary change, which he termed “genetic assimilation”.1,2 The idea was that certain environmental or genetic factors can disrupt the normally canalized (i.e., stable) course of development of living organisms. This disruption may then generate phenotypic variation that could allow a population to persist in a novel or stressful environment until new mutations would eventually let natural selection fix (“assimilate”) the advantageous phenotypic variants.

Anton Marty (1847-1914) is known to be the most faithful pupil of Franz Brentano. As a matter of fact, most of his philosophical ideas find their source in the works of his master. Yet, the faithfulness of Marty is not constant. As the rich correspondence between the two thinkers shows, Marty elaborates an original theory of intentionality from ca. 1904 onward. This theory is based on the idea that intentionality is a process of mental assimilation (ideelle Verähnlichung), a process (...) at the core of which lies a sui generis relation of “ideal similitude” holding between a thinking subject and its object. This study spells out the Martyian notion of mental assimilation and traces back Marty’s evolution from his earlier position (prominently described in the recently published Deskriptive Psychologie of 1893-1894) to his final view as it is found in the Untersuchungen of 1908. It turns out that besides Brentano, Husserl is a key figure in that evolution. Such a “genetic”elucidation of Marty’s last theory is required in order to reach the main goal of this paper, namely: the clarification of Marty’s degree of dependence upon Brentano with respect to the theory of intentionality. That being said, we do not merely intend to compare the mature Marty with Brentano: our “genetic” considerations will also allow us to describe the interaction between the two thinkers before 1904. Accordingly, we begin by presenting Brentano’s own position on intentionality in discussing its two currently competing readings, namely the “discontinuist” and the “continuist” one. Against a recent interpretation, we argue that Marty’s endorsement of a “discontinuist” reading is not based on a misunderstanding of Brentano’s position. (shrink)

This chapter examines when and how mental simulation--the consideration of alternatives to present reality--produces emotional responses that reflect either contrast or assimilation. The chapter begins with a description of a comparison domain that is most commonly associated with mental simulation--counterfactual thinking. Then the authors consider how mental simulation plays a critical role in determining assimilative and contrastive responses to other type of comparisons. The chapter concludes with a presentation of a model of mental simulation-based comparison processes and describe its (...) relationship to other contemporary comparison models. (shrink)

Using the two cases of the Icelandic Health Sector Database and Russian initiatives in biobanking, the article criticizes the view of narratives and imaginaries as a sufficient and unproblematic means of shaping public understanding of genetics and justifying population-wide projects. Narrative representations of national biobanking engage particular imaginaries that are not bound by the universal normative framework of human rights, promote affective thinking, distract the public from recognizing and discussing tangible ethical and socioeconomic issues, and harm trust in science and (...) technology. In the Icelandic case, the presentation of the project in association with national imaginaries concealed its market identity and could lead to the commodification of biodata. In the Russian case, framing in terms of "genetic sovereignty" and "civilizational code" offers pretexts for state securitization. Adherence to normative framework of human rights and public discussion of genetics in an argumentative and factual mode can counter these trends. (shrink)

Genetically engineered (GE) insects, such as the GE OX513A Aedes aegypti mosquitoes, have been designed to suppress their wild-type populations so as to reduce the transmission of vector-borne diseases in humans. Apart from the ecological and epidemiological uncertainties associated with this approach, such biotechnological approaches may be used by individual governments or the global community of nations to avoid addressing the underlying structural, systemic causes of those infections... We discuss here key ethical questions raised by the use of GE mosquitoes, (...) with the aim of fostering discussion between the public, researchers, policy makers, healthcare organizations, and regulatory agencies at the local, national, and international levels. We affect that goal by outlining a procedural approach to decision-making about the use of the “biotechnology” that goes beyond “community engagement.” The protocol we advocate for entails informed deliberations and decision-making at the community level. It is designed to ensure that the voices of the marginalized and vulnerable groups that would be disproportionately affected by the decision are heard during the community-wide discussions. Moreover, we make the case that the values embedded in the risk assessment should be identified so that the community can make an informed decision about the use of GE insects. In addition, we advocate for the involvement of a variety of actors whose responsibility would be to ensure that the community has the opportunity to make an informed decision based on deliberations about the use of the “biotechnology.”.

In this paper I present an argument in favour of a parental duty to use preimplantation genetic diagnosis (PGD). I argue that if embryos created in vitro were able to decide for themselves in a rational manner, they would sometimes choose PGD as a method of selection. Couples, therefore, should respect their hypothetical choices on a principle similar to that of patient autonomy. My thesis shows that no matter which moral doctrine couples subscribe to, they ought to conduct the (...) PGD procedure in the situations when it is impossible to implant all of the created embryos and if there is a significant risk for giving birth to a child with a serious condition. (shrink)

In this paper I argue that the extent to which a human trait is genetically caused can causally depend upon whether the trait is categorized within human genetics as genetically caused. This makes the kind genetically caused trait an interactive kind. I demonstrate that this thesis is both conceptually coherent and empirically plausible. I outline the core rationale of this thesis and demonstrate its conceptual coherence by drawing upon Waters’ (2007) analysis of genetic causation. I add empirical plausibility to (...) the thesis by describing a hypothetical but empirically plausible mechanism by which the fact that obesity is categorized as genetically caused within human genetics increases the extent to which obesity is in fact genetically caused.

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 core of Zimmerman’s picture posits an inverse correlation between an action’s automaticity and belief’s role in the action’s execution. This proposal faces serious problems. First, high-attention, high-control actions don’t seem to heighten awareness of one’s beliefs. Second, low-attention, low-control actions are caused by the same states at play when executing high-attention, high-control actions, in which case there is no ontological difference in the states involved in these behaviors. Third, on Zimmerman’s view it is unclear what it is for a (...) state to be involved in behaviors at all, as the basic realist response—that beliefs cause behavior—is unavailable to a Zimmerman-style pragmatist. Lastly, if Zimmerman's view were right and low-level behaviors weren't caused by beliefs, then we should turn our attention to those states instead, as most of our behavior isn’t executed under conditions of high control and attention.

The article proposes to further develop the ideas of the Extended Evolutionary Synthesis by including into evolutionary research an analysis of phenomena that occur above the organismal level. We demonstrate that the current Extended Synthesis is focused more on individual traits (genetically or non-genetically inherited) and less on community system traits (synergetic/organizational traits) that characterize transgenerational biological, ecological, social, and cultural systems. In this regard, we will consider various communities that are made up of interacting populations, and for which the (...) individual members can belong to the same or to different species. Examples of communities include biofilms, ant colonies, symbiotic associations resulting in holobiont formation, and human societies. The proposed model of evolution at the level of communities revises classic theorizing on the major transitions in evolution by analyzing the interplay between community/social traits and individual traits, and how this brings forth ideas of top-down regulations of bottom-up evolutionary processes (collaboration of downward and upward causation). The work demonstrates that such interplay also includes reticulate interactions and reticulate causation. In this regard, we exemplify how community systems provide various non-genetic ‘scaffoldings’, ‘constraints’, and ‘affordances’ for individual and sociocultural evolutionary development. Such research complements prevailing models that focus on the vertical transmission of heritable information, from parent to offspring, with research that instead focusses on horizontal, oblique and even reverse information transmission, going from offspring to parent. We call this reversed information transfer the ‘offspring effect’ to contrast it from the ‘parental effect’. We argue that the proposed approach to inheritance is effective for modelling cumulative and distributed developmental process and for explaining the biological origins and evolution of language.

Genetic engineering technologies are a subclass of the biotechnology family, and are concerned with the use of laboratory-based technologies to intervene with a given organism at the genetic level, i.e., the level of its DNA. This class of technologies could feasibly be used to treat diseases and disabilities, create disease-resistant crops, or even be used to enhance humans to make them more resistant to certain environmental conditions. However, both therapeutic and enhancement applications of genetic engineering raise serious (...) ethical concerns. This paper examines various objections to genetic engineering (as applied to humans) which have been raised in the literature, and presents a new way to frame these issues, and to look for solutions. Specifically, this paper frames genetic engineering technologies within the ‘design turn in applied ethics’ lens and thus situates these technologies as covarying with societal forces. The value sensitive design (VSD) approach to technology design is then appropriated as the conceptual framework in which genetic engineering technologies can be considered so that they can be designed for important human values. By doing so, this paper brings further nuance to the scholarship on genetic engineering technologies by discussing the sociotechnicity of genetic engineering systems rather than framing them as value-neutral tools that either support or constrain values based on how they are used.

This paper outlines a critique of the use of the genetic variance–covariance matrix (G), one of the central concepts in the modern study of natural selection and evolution. Specifically, I argue that for both conceptual and empirical reasons, studies of G cannot be used to elucidate so-called constraints on natural selection, nor can they be employed to detect or to measure past selection in natural populations – contrary to what assumed by most practicing biologists. I suggest that the search (...) for a general solution to the difficult problem of identifying causal structures given observed correlation’s has led evolutionary quantitative geneticists to substitute statistical modeling for the more difficult, but much more valuable, job of teasing apart the many possible causes underlying the action of natural selection. Hence, the entire evolutionary quantitative genetics research program may be in need of a fundamental reconsideration of its goals and how they correspond to the array of mathematical and experimental techniques normally employed by its practitioners.

The biomedical literature makes extensive use of the concept of a genetic program. So far, however, the nature of genetic programs has received no satisfactory elucidation from the standpoint of computer science. This unsettling omission has led to doubts about the very existence of genetic programs, on the grounds that gene regulatory networks lack a predetermined schedule of execution, which may seem to contradict the very idea of a program. I show, however, that we can make perfect (...) sense of genetic programs, if only we abandon the preconception that all computers have a von Neumann architecture. Instead, genetic programs instantiate the computational architecture of Post–Newell Production Systems. That is, genetic programs are unordered sets of conditional instructions, instructions that fire independently when their conditions are matched. For illustration I present a paradigm Production System that regulates the functioning of the well-known lac operon of E. coli. On close reflection it turns out that not only genes, but also proteins encode instructions. I propose, therefore, to rename genetic programs to biomolecular programs. Biomolecular and/or genetic programs, and the cellular computers than run them, are to be understood not as von Neumann computers, but as Post–Newell production systems. (shrink)

There are many advantages and disadvantages to central locations. These have shown themselves in the long course of European history. In times of peace, there are important economic and cultural advantages (to illustrate: the present area of the Czech Republic was the richest country in Europe between the two World Wars). There are cross-currents of trade and culture in central Europe of great advantage. For, cultural cross-currents represent a potential benefit in comprehension and cultural growth. But under threat of large-scale (...) conflict, these locations have proved extremely dangerous. Historically, Germany and Austria may be regarded as having had two chief models of their relationships to Europe. In the Holy Roman Empire, Germany was at the center of an aspiring “universalistic” European cosmopolitanism. (In some ways similar to the present situation of the European Union.) Austria maintained a great multi¬cultural empire, until it was destroyed in the First Word War. Generally, middle-European powers have promoted the integration of European diversity, when peace and stability have been plausible objectives. But when European diversity has declined toward ethnic or national conflict, Germany has drawn away from Europe and into itself, seeking inner unity and distinctness to protect it against possible combinations of enemies. This is true of central Europe generally, in degree, but interest often centers on Germany. Generally, central Europe is a cultural pressure cooker. (shrink)

In recent years, humans’ ability to selectively modify genes has increased dramatically as a result of the development of new, more efficient, and easier genetic modification technology. In this paper, we argue in favor of using this technology to improve the welfare of agricultural animals. We first argue that using animals genetically modified for improved welfare is preferable to the current status quo. Nevertheless, the strongest argument against pursuing gene editing for welfare is that there are alternative approaches to (...) addressing some of the challenges of modern agriculture that may offer ethical advantages over genetic modification; namely, a dramatic shift towards plant-based diets or the development of in vitro meat. Nevertheless, we provide reasons for thinking that despite these possible comparative disadvantages there are important reasons for continuing the pursuit of welfare improvements via genetic modification.

This article illustrates in which sense genetic determinism is still part of the contemporary interactionist consensus in medicine. Three dimensions of this consensus are discussed: kinds of causes, a continuum of traits ranging from monogenetic diseases to car accidents, and different kinds of determination due to different norms of reaction. On this basis, this article explicates in which sense the interactionist consensus presupposes the innate?acquired distinction. After a descriptive Part 1, Part 2 reviews why the innate?acquired distinction is under (...) attack in contemporary philosophy of biology. Three arguments are then presented to provide a limited and pragmatic defense of the distinction: an epistemic, a conceptual, and a historical argument. If interpreted in a certain manner, and if the pragmatic goals of prevention and treatment are taken into account, then the innate?acquired distinction can be a useful epistemic tool. It can help, first, to understand that genetic determination does not mean fatalism, and, second, to maintain a system of checks and balances in the continuing nature?nurture debates. (shrink)

The cumulative impact of enhancement technologies may alter the human species in the very long-term future. In this article, I will start showing how radical genetic enhancements may accelerate the conversion into a novel species. I will also clarify the concepts of ‘biological species’, ‘transhuman’ and ‘posthuman’. Then, I will summarize some ethical arguments for creating a transhuman or posthuman species with a substantially higher level of well-being than the human one. In particular, I will present what I shall (...) call the Principle of the Best Interests of Posthumanity, which states that the enhancement of the human and transhuman species must be directed towards the creation of a posthuman existence that is substantially more valuable than its predecessors. I suggest that human extinction may be considered, within that principle, as one of the best interests of posthumanity. Finally, I will develop three objections that make that principle unattractive and that show that pursuing a full-blown programme of posthuman evolution is ethically flawed. (shrink)

With the recent report of a live birth after use of Mitochondrial replacement therapy, sometimes called ‘Three-parent IVF’, the clinical application of the technique is fast becoming a reality. While the United Kingdom allows the procedure under regulatory scrutiny, it remains effectively outlawed in many other countries. We argue that such prohibitions may violate individuals’ procreative rights, grounded in individuals’ interest in genetic affinity. The interest in genetic affinity was recently endorsed by Singapore’s highest court, reflecting an emphasis (...) on the importance of biological ties found across the globe. We apply that reasoning to make the case for a right to ‘Three-parent IVF’. (shrink)

The idea that development is the expression of information accumulated during evolution and that heredity is the transmission of this information is surprisingly hard to cash out in strict, scientific terms. This paper seeks to do so using the sense of information introduced by Francis Crick in his sequence hypothesis and central dogma of molecular biology. It focuses on Crick's idea of precise determination. This is analysed using an information-theoretic measure of causal specificity. This allows us to reconstruct some of (...) Crick's claims about information in transcription and translation. Crick's approach to information has natural extensions to non-coding regions of DNA, to epigenetic marks, and to the genetic or environmental upstream causes of those epigenetic marks. Epigenetic information cannot be reduced to genetic information. The existence of biological information in epigenetic and exogenetic factors is relevant to evolution as well as to development.

In a recent publication Tom Douglas and Katrien Devolder have proposed a new account of genetic parenthood, building on the work of Heidi Mertes. Douglas and Devolder’s account aims to solve, among other things, the question of who are the genetic parents of an individual created through somatic cell nuclear transfer (i.e. cloning): (a) the nuclear DNA provider or (b) the progenitors of the nuclear DNA provider. Such a question cannot be answered by simply appealing to the folk (...) account of genetic parenthood, according to which the genetic parents of an individual are those individuals who produced the egg and sperm, respectively, which fused to create the embryo. It cannot be so as in cloning there is no fertilization as such. In this article I critically examine Douglas and Devolder’s new account of genetic parenthood and demonstrate that it is vulnerable to counterexamples that exploit the lack of a condition specifying that genetic parents should cause a child’s coming into existence.

I use a contrastive theory of causal explanation to analyze the notion of a genetic trait.

Two families of mathematical methods lie at the heart of investigating the hierarchical structure of genetic variation in Homo sapiens: /diversity partitioning/, which assesses genetic variation within and among pre-determined groups, and /clustering analysis/, which simultaneously produces clusters and assigns individuals to these “unsupervised” cluster classifications. While mathematically consistent, these two methodologies are understood by many to ground diametrically opposed claims about the reality of human races. Moreover, modeling results are sensitive to assumptions such as preexisting theoretical commitments (...) to certain linguistic, anthropological, and geographic human groups. Thus, models can be perniciously reified. That is, they can be conflated and confused with the world. This fact belies standard realist and antirealist interpretations of “race,” and supports a pluralist conventionalist interpretation. (shrink)

Imagine a world where everyone is healthy, intelligent, long living and happy. Intuitively this seems wonderful albeit unrealistic. However, recent scienti c breakthroughs in genetic engineering, namely CRISPR/Cas bring the question into public discourse, how the genetic enhancement of humans should be evaluated morally. In 2001, when preimplantation genetic diagnosis (PGD) and in vitro fertilisation (IVF), enabled parents to select between multiple embryos, Julian Savulescu introduced the principle of procreative bene cence (PPB), stating that parents have the (...) obligations to choose the child that is expected to have the best life. In this paper I argue that accepting the PPB and the consequentialist principle (CP) that two acts with the same consequences are morally on par, commits one to accepting the parental obligation of genetically enhancing one's children.

In this paper, I analyze the ethical implications of genetic enhancement within the specific framework of the “child’s right to an open future” argument (CROF). Whilst there is a broad ethical consensus that genetic modifications for eradicating diseases or disabilities are in line with – or do not violate – CROF, there is huge disagreement about how to ethically understand genetic enhancement. Here, I analyze this disagreement and I provide a revised formulation of the argument in the (...) specific field of genetic enhancement. First, I argue that CROF is not in contrast with every kind of enhancement. I subsequently discuss whether CROF requires some moral obligations to enhance progeny. My argument is that parents do not have the moral obligation to open as many options as possible for their children. Rather, they should provide them with a reasonable range of opportunities. Finally, I contend that the moral obligations required by CROF are directly dependent on what Allen Buchanan calls the ‘dominant cooperative framework’ in a given society. I conclude by claiming that, at present, parents are not morally obliged to genetically enhance their children since a non-enhanced person already might have access to a reasonable range of opportunities. However, the moral obligation to enhance progeny might arise if a structural modification of the dominant cooperative framework occurs. (shrink)

Current debate and policy surrounding the use of genetic editing in humans often relies on a binary distinction between therapy and human enhancement. In this paper, we argue that this dichotomy fails to take into account perhaps the most significant potential uses of CRISPR-Cas9 gene editing in humans. We argue that genetic treatment of sporadic Alzheimer’s disease, breast- and ovarian-cancer causing BRCA1/2 mutations and the introduction of HIV resistance in humans should be considered within a new category of (...) genetic protection treatments. We find that if this category is not introduced, life-altering research might be unnecessarily limited by current or future policy. Otherwise ad hoc decisions might be made, which introduce a risk of unforeseen moral costs, and might overlook or fail to address some important opportunities. (shrink)

In my essay I consider the imaginary case of a future mother who refuses to undergo genetic alteration on her germline although she knows that her, as yet unconceived, child will have a serious genetic disorder. I analyze the good and bad points of two branches of arguments directed against her decision, consequentialist and rights-based. Then I discuss whether accepting one line of these arguments or the other makes a difference in moral assessment. I conclude that, although from (...) the preanalytical perspective we strongly oppose the refusal of genetic treatment in my imaginary case, it is probably impossible to construct one coherent theory which embraces all possible moral dilemmas triggered by our actions which affect the number and the identity of future people.

We describe an approach to measuring biological information where ‘information’ is understood in the sense found in Francis Crick’s foundational contributions to molecular biology. Genes contain information in this sense, but so do epigenetic factors, as many biologists have recognized. The term ‘epigenetic’ is ambiguous, and we introduce a distinction between epigenetic and exogenetic inheritance to clarify one aspect of this ambiguity. These three heredity systems play complementary roles in supplying information for development. -/- We then consider the evolutionary significance (...) of the three inheritance systems. Whilst the genetic inheritance system was the key innovation in the evolution of heredity, in modern organisms the three systems each play important and complementary roles in heredity and evolution. -/- Our focus in the earlier part of the paper is on ‘proximate biology’, where information is a substantial causal factor that causes organisms to develop and causes offspring to resemble their parents. But much philosophical work has focused on information in ‘ultimate biology’. Ultimate information is a way of talking about the evolutionary design of the mechanisms of development and inheritance. We conclude by clarifying the relationship between the two. Ultimate information is not a causal factor that acts in development or heredity, but it can help to explain the evolution of proximate information, which is. (shrink)

This paper concerns Jean Piaget's (1896–1980) philosophy of science and, in particular, the picture of scientific development suggested by his theory of genetic epistemology. The aims of the paper are threefold: (1) to examine genetic epistemology as a theory concerning the growth of knowledge both in the individual and in science; (2) to explicate Piaget's view of ‘scientific progress’, which is grounded in his theory of equilibration; and (3) to juxtapose Piaget's notion of progress with Thomas Kuhn's (1922–1996). (...) Issues of scientific continuity, scientific realism and scientific rationality are discussed. It is argued that Piaget's view highlights weaknesses in Kuhn's ‘discontinuous’ picture of scientific change. (shrink)

The primary responsibility of the US Food and Drug Administration is to protect public health by ensuring the safety of the food supply. To that end, it sometimes conducts risk assessments of novel food products, such as genetically modified food. The FDA describes its regulatory review of GM food as a purely scientific activity, untainted by any normative considerations. This paper provides evidence that the regulatory agency is not justified in making that claim. It is argued that the FDA’s policy (...) stance on GM food is shaped by neoliberal considerations. The agency’s review of a genetically engineered animal, the AquAdvantage salmon, is used as a case study to track the influence of neoliberalism on its regulatory review protocol. After that, an epistemic argument justifying public engagement in the risk assessment of new GM food is outlined. It is because risk evaluations involve normative judgments, in a democracy, layperson representatives of informal epistemic communities that could be affected by a new GM food should have the opportunity to decide the ethical, political or other normative questions that arise during the regulatory review of that entity.

-/- 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.

Jeremy Williams has argued that if we are committed to a liberal pro-choice stance with regard to selective abortion for disability, we will be unable to justify the prohibition of sex selective abortion. Here, I apply his reasoning to selective abortion based on other traits pregnant women may decide are undesirable. These include susceptibility to disease, level of intelligence, physical appearance, sexual orientation, religious belief and criminality—in fact any traits attributable to some degree to a genetic component. Firstly, I (...) review Williams’ argument, which claims that if a woman is granted the right to abort based on fetal impairment, then by parity of reasoning she should also be granted the right to choose sex selective abortion. I show that these same considerations that entail the permissibility of sex selective abortion are also applicable to genetic selection abortion. I then examine the objections to sex selective abortion that Williams considers and rejects, and show that they also lack force against genetic selection abortion. Finally, I consider some additional objections that might be raised, and conclude that a liberal pro-choice stance on selective abortion for disability entails the permissibility of selective abortion for most genetic traits.

Bioconservative commentators argue that parents should not take steps to modify the genetics of their children even in the name of enhancement because of the damage they predict for values, identities and relationships. Some commentators have even said that adults should not modify themselves through genetic interventions. One commentator worries that genetic modifications chosen by adults for themselves will undermine moral agency, lead to less valuable experiences and fracture people's sense of self. These worries are not justified, however, (...) since the effects of modification will not undo moral agency as such. Adults can still have valuable experiences, even if some prior choices no longer seem meaningful. Changes at the genetic level will not always, either, alienate people from their own sense of self. On the contrary, genetic modifications can help amplify choice, enrich lives and consolidate identities. Ultimately, there is no moral requirement that people value their contingent genetic endowment to the exclusion of changes important to them in their future genetic identities. Through weighing risks and benefits, adults also have the power to consent to—and assume the risks of—genetic modifications for themselves in a way not possible in prenatal genetic interventions.

Genetic explanations of religious belief, such as Freud’s analysis of theism as ‘a neurotic relic’, pose a problem for theists: how far do such explanations establish the irrationality of religious belief? I argue that genetic analyses of belief suffer from a number of limitations. Showing that some reason-irrelevant factor or factors were sufficient to produce conviction on some occasion would not establish that they were necessary in every case of religious conviction. Showing that reason-irrelevant factors were both necessary (...) and sufficient to produce conviction would not establish that reason-relevant factors were entirely absent. And showing that reason-relevant factors played no role in the adoption of the belief would not establish that they were absent in its continued retention. I conclude that we will profitably investigate the plausibility of religious beliefs by attending to the reasons that can be given for or against them rather than by speculating about their causes.

The soaring promises made by personalized genetic medicine advocates are probably loftier than those in any other medical or scientific realm today. Are they justified?

In this new post-genomic age of medicine and biomedical technology, there will be novel approaches to understanding disease, and to finding drugs and cures for diseases. Hundreds of new “disease genes” thought to be the causative agents of various genetic maladies will be identified and added to the list of hundreds of such genes already identified. Based on this knowledge, many new genetic tests will be developed and used in genetic screening programs. Genetic screening is the (...) foundation upon which reproductive technologies such as pre-natal diagnosis (PND) and preimplantation genetic diagnosis (PGD) are based. Genetic information arising from the human genome may also be used in attempts to redesign the human genetic inheritance by engineering the human germline (germline engineering). In each of these technologies—PND, PGD, and germline engineering—there are serious ethical and social concerns. Moreover, all three are eugenic in nature because they strive to control which genes are passed down to future generations. The goals of this article are threefold: 1) to introduce the science behind the three technologies; 2) to give a brief overview of eugenics in the past century and show how these genetic technologies are eugenic; and 3) to present a vision of social justice that rejects the genetic determinism upon which eugenics is based and embraces a holistic, ecological view of nature and humanity.

The chapter explains why evolutionary genetics – a mathematical body of theory developed since the 1910s – eventually got to deal with culture: the frequency dynamics of genes like “the lactase gene” in populations cannot be correctly modeled without including social transmission. While the body of theory requires specific justifications, for example meticulous legitimations of describing culture in terms of traits, the body of theory is an immensely valuable scientific instrument, not only for its modeling power but also for the (...) amount of work that has been necessary to build, maintain, and expand it. A brief history of evolutionary genetics is told to demonstrate such patrimony, and to emphasize the importance and accumulation of statistical knowledge therein. The probabilistic nature of genotypes, phenogenotypes and population phenomena is also touched upon. Although evolutionary genetics is actually composed by distinct and partially independent traditions, the most important mathematical object of evolutionary genetics is the Mendelian space, and evolutionary genetics is mostly the daring study of trajectories of alleles in a population that explores that space. The ‘body’ is scientific wealth that can be invested in studying every situation that happens to turn out suitable to be modeled as a Mendelian population, or as a modified Mendelian population, or as a population of continuously varying individuals with an underlying Mendelian basis. Mathematical tinkering and justification are two halves of the mutual adjustment between the body of theory and the new domain of culture. Some works in current literature overstate justification, misrepresenting the relationship between body of theory and domain, and hindering interdisciplinary dialogue. (shrink)

Analytic philosophers tend to agree that intentional parental genetic shaping and intentional parental environmental shaping for the same feature are, normatively, on a par. I challenge this view by advancing a novel argument, grounded in the value of fair relationships between parents and children: Parental genetic shaping is morally objectionable because it unjustifiably exacerbates the asymmetry between parent and child with respect to the voluntariness of their entrance into the parent–child relationship. Parental genetic shaping is, for this (...) reason, different from and more objectionable than parental environmental shaping. I introduce a distinction between procreative decisions one makes qua mere procreator—that is, without the intention to rear the resulting child—and procreative decisions one makes qua procreator-and-future childrearer. Genetic shaping is objectionable when undertaken in the latter capacity: Both selection and enhancement are objectionable because they introduce an unnecessary and avoidable inequality in the parent–child relationship; in the case of enhancement, this also results in harm to the future child.

Ongoing research in the fields of genetics and biotechnology hold the promise of improved diagnosis and treatment of genetic diseases, and potentially the development of individually tailored pharmaceuticals and gene therapies. Difficulty, however, arises in determining how these services are to be evaluated and integrated equitably into public health care systems such as Canada's. The current context is one of increasing fiscal restraint on the part of governments, limited financial resources being dedicated to health care, and rising costs for (...) new health care services and technologies. This has led to increasing public debate in the last few years about how to reform public health care, and whether we should prohibit, permit or perhaps even encourage private purchase of health care services. ;In Canada, some of these concerns have crystallized around the issue of gene patents and commercial genetic testing, in particular as illustrated by the case of Myriad Genetics' patented BRACAnalysis test for hereditary breast and ovarian cancer. While most Canadians who currently access genetic services do so through the public health care system, for those with the means, private purchase is becoming an option. This situation raises serious concerns---about justice in access to health care; about continued access to safe and reliable genetic testing supported by unbiased patient information; and about the broader effects of commercialization for ongoing research and the Canadian public health care system. Commercial genetic testing presents a challenge to health care professionals, policy analysts, and academics concerned with the social, ethical and policy implications of new genetic technologies. Using the Myriad case as an exemplar, tools from moral philosophy, the social sciences, and health policy and law will be brought to bear on the larger issues of how as a society we should regulate commercial research and product development, and more coherently decide which services to cover under public health insurance and which to leave to private purchase. Generally, the thesis is concerned with the question of "how best to bring capital, morality, and knowledge into a productive and ethical relationship". (shrink)

One of the most difficult issues to sort out morally is our obligation to future generations. Most individuals feel that they do indeed have some kind of obligation, but face difficulty in explaining the exact nature of the obligation. For one, it seems impossible to know the wants and desires of future generations, and furthermore the existence of the persons we are obligated to is entirely dependent upon the choices that we in fact make. In essence, we could shape future (...) generations so that they desire exactly what we provide for them. It seems that no matter what principle we adopt that is based upon these potential individuals we are led to absurd conclusions. Gregory Kavka calls this moral grappling the Paradox of Future Individuals. I believe that the ethical concerns surrounding genetic engineering should be seen as a specific instantiation of this Paradox and that by examining both we may be able to come up with some sort of working solution. Derek Parfit pleads ignorance as to a solution to this Paradox after an extensive exegesis on the issue, but as we may not be that far from shopping a genetic supermarket to determine the characteristics of our children I don’t believe we can settle for that conclusion. We will begin by examining the Paradox and suggested solutions to the Paradox. Next I will address how the Paradox relates directly to genetic engineering and discuss how rights-based arguments aimed against genetic engineering fail because of the nature of identity. Then I will consider how David Heyd’s Genero-centric principle applies to genetic engineering specifically and how a modified version of that principle may guide us out of the Paradox of Future Individuals in general. This solution may not be acceptable to utilitarian sensibilities, but it is because the numbers don’t add up that we may need to appeal to a different principle entirely. (shrink)

Reproductive genetic technologies allow parents to decide whether their future children will have or lack certain genetic predispositions. A popular model that has been proposed for regulating access to RGTs is the ‘genetic supermarket’. In the genetic supermarket, parents are free to make decisions about which genes to select for their children with little state interference. One possible consequence of the genetic supermarket is that collective action problems will arise: if rational individuals use the (...) class='Hi'>genetic supermarket in isolation from one another, this may have a negative effect on society as a whole, including future generations. In this article we argue that RGTs targeting height, innate immunity, and certain cognitive traits could lead to collective action problems. We then discuss whether this risk could in principle justify state intervention in the genetic supermarket. We argue that there is a plausible prima facie case for the view that such state intervention would be justified and respond to a number of arguments that might be adduced against that view.

_ Source: _Page Count 30 Millions of children worldwide could benefit from adoption. One could argue that prospective parents have a pro tanto duty to adopt rather than create children. For the sake of argument, I assume there is such a duty and focus on a pressing objection to it. Prospective parents may prefer that their children are genetically related to them. I examine eight reasons prospective parents have for preferring genetic children: for parent-child physical resemblance, for family resemblance, (...) for psychological similarity, for the sake of love, to achieve a kind of immortality, for the genetic connection itself, to be a procreator, and to experience pregnancy. I argue that, with the possible exception of the pregnancy desire, these reasons fail to defeat a duty to adopt a child rather than create one, even assuming that we do have some leeway to favor our own interests.

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

Common sense morality and legislations around the world ascribe normative relevance to biological connections between parents and children. Procreators who meet a modest standard of parental competence are believed to have a right to rear the children they brought into the world. I explore various attempts to justify this belief and find most of these attempts lacking. I distinguish between two kinds of biological connections between parents and children: the genetic link and the gestational link. I argue that the (...) second can better justify a right to rear.

We seek to develop a plausible conception of genetic parenthood, taking a recent discussion by Heidi Mertes as our point of departure. Mertes considers two conceptions of genetic parenthood—one invoking genetic resemblance, and the other genetic inheritance—and presents counter-examples to both conceptions. We revise Mertes’ second conception so as to avoid these and related counter-examples.
