Genetics

The fact that genes and environment contribute differentially to variation in human behaviors, traits and attitudes is central to the field of behavior genetics. Perceptions about these differential contributions may affect ideas about human agency. We surveyed two independent samples (N = 301 and N = 740) to assess beliefs about free will, determinism, political orientation, and the relative contribution of genes and environment to 21 human traits. We find that lay estimates of genetic influence on these traits cluster into (...) four distinct groups, which differentially predict beliefs about human agency, political orientation, and religiosity. Despite apparent ideological associations with these beliefs, the correspondence between mean lay estimates and published heritability estimates for the surveyed traits is large (r = .77). Belief in genetic determinism emerges as a modest predictor of accuracy in these lay estimates. Additionally, educated mothers with multiple children emerge as particularly accurate in their estimates of the genetic contribution to these traits. (shrink)

More than a decade of exacting scientific research involving paleontological fragments and ancient DNA has lately produced a series of pronouncements about a purportedly novel population of archaic hominins dubbed “the Denisova.” The science involved in these matters is both technically stunning and, socially, at times a bit reckless. Here I discuss the responsibilities which scientists incur when they make inductively risky pronouncements about the different relative contributions by Denisovans to genomes of members of apparent subpopulations of current humans. This (...) science is sensational: it is science which empirically speculates, to the public delight’s and entertainment, about scintillating topics such as when humans evolved, where we came from, and who else we were having sex with during our early hominin history. An initial characterization of sensational science emerges from my discussion of the case, as well as a diagnosis of an interactive phenomenon termed amplified inductive risk. (shrink)

Creation Ethics illuminates an array of issues in "reprogenetics" through the lens of moral philosophy. With novel frameworks for understanding prenatal moral status and human identity, David DeGrazia tackles the ethics of abortion and embryo research, genetic enhancement and prenatal genetic interventions, procreation and parenting, and obligations to future generations.

The article considers the study of science of genetics and a brief history of its creation and the creation of the laws of heredity.

The advent of CRISPR has drastically moved the possibility of genetically modifying human genomes from the space of science fiction into nearby reality. Whether one considers the positive results f...

The Covid-19 pandemic has demonstrated the potential of genomic technologies for the detection and surveillance of infectious diseases. Pathogen genomics is likely to play a major role in the future of research and clinical implementation of genomic technologies. However, unlike human genetics, the specific ethical and social challenges associated with the implementation of infectious disease genomics has received comparatively little attention. In this paper, we contribute to this literature, focusing on the potential consequences for individuals and communities of the use (...) of these technologies. We concentrate on areas of challenges related to privacy, stigma, discrimination and the return of results in the cases of the surveillance of known pathogens, metagenomics and host genomics.

This paper introduces the reconstitutor as a comprehensive unit of heredity within the context of evolutionary research. A reconstitutor is the structure resulting from a set of relationships between different elements or processes that are actively involved in the recreation of a specific phenotypic variant in each generation regardless of the biomolecular basis of the elements or whether they stand in a continuous line of ancestry. Firstly, we justify the necessity of introducing the reconstitutor by showing the limitations of other (...) evolutionary conceptions of the unit of heredity, such as the replicator, the reproducer, and the Darwinian individual. We argue that these conceptions are based on the requirement of lineage formation, which we argue to be unnecessary for the existence of evolutionary heredity. In the second part, we introduce the reconstitutor, which we base on the concept of Stability of Traits, and illustrate how it covers cases of hereditary phenomena not covered by the previous accounts. Secondly, we illustrate how the reconstitutor could serve as a platform to rethink ecological inheritance and other forms of inheritance that have been recently introduced under the song/singer model of evolution.

Much of what has been written about the history of medical genetics in North America has focused on physician involvement in eugenics and the transition from heredity counseling to genetic counseling in the United States. What are typically missing in these accounts are details concerning the formation of a new medical specialty, i.e., medical genetics, and Canada’s involvement in specialty formation. Accordingly, this paper begins to fill in gaps by investigating, on the one hand, the history of American and Canadian (...) geneticists working together to support the creation of examining and teaching positions in human genetics in North American medical schools and, on the other, working independently of one another to monitor the rate and direction of workloads and patient access to local genetic counseling and laboratory services and, subsequently, achieve recognition for medical genetics as a medical specialty at the national level.

Primate conservationists monitor the numbers of primate populations around the world as they decline at the hands of human activity. However, it is important to make realistic assessments of the survival prospects of different endangered primate species. Considerations should be made of behavioral genetic, and ecological traits that might create greater or lesser vulnerability to extinction given the same human impacts. A brief consideration of two rare Asian monkeys, the lion-tailed macaque and the proboscis monkey, illustrates the need to focus (...) on the unique complex of traits of each species to devise realistic conservation strategies. General unifying models of vulnerability to extinction are relatively unhelpful. (shrink)

The Norwegian Association for Heredity Research played a key role in the rise of genetics as a research field in Norway. The immediate background of its establishment in 1919 was the need for an organization that could clarify scientific issues regarding eugenics and coordinate Norwegian representation in the organized international eugenics movement. The Association never assumed this role. Instead, Norway was represented in the international eugenics movement by the so-called Norwegian Consultative Eugenics Commission, whose leader, Jon Alfred Mjøen, was dismissed (...) as a pseudo-scientist by Norwegian geneticists. The paper explores the Association’s role in defining and delimiting scientific expert knowledge in the field of genetics and eugenics in Norway. It demonstrates how struggles about academic authority on the national arena were intertwined with struggles about representation and impact in the international eugenics movement and how transnational scientific networks where mobilized to legitimize and delegitimize notions about Nordic race supremacy, racial mixing and the politics of eugenic sterilizations.

Scientific knowledge of how genes work is giving human beings unprecedented power to shape future human lives, for better or for worse. People involved in government, business and science are facing new questions related to the application of genetic technologies to human beings. Our technical knowledge is growing fast, but does our moral wisdom grow at the same rate?

This book brings together an international collection of experts in reproductive ethics, law, disability studies, and medicine to explore the challenging future of reproduction and children. From the medical to the social and from the financial to the legal, the authors explore the expanding impact of reproductive genetics on our society. New advances in genetic technologies are revolutionizing the practice of reproductive medicine. We have expanded our ability to detect genetic changes in embryos and fetuses in ways that potentially allow (...) to identify, treat, or prevent a growing range of diseases. The development of gene-editing technologies raises questions about the possibility of removing disease-causing variants from embryos before pregnancy implantation. The growing sophistication of prenatal genomic sequencing offers us glimpses into the whole genome of the developing fetus. And, the increasingly sophisticated science of 'gene matching' allows us greater and greater foreknowledge of how the genomes of two individuals will combine in a future child. This is an indispensable book on the newest developments in bioethics caused by the sciences.

The focus of this chapter will be Kant’s understanding of Hume, and its impact on Kant’s critical philosophy. Contrary to the traditional reading of this relationship, which focuses on Kant’s (admittedly real) dissatisfaction with Hume’s account of causation, my discussion will focus on broader issues of philosophical methodology. Following a number of recent interpreters, I will argue that Kant sees Hume as raising, in a particularly forceful fashion, a ‘demarcation challenge’ concerning how to distinguish the legitimate use of reason in (...) (say) natural scientific contexts from the illegitimate use of it in (say) dogmatic metaphysics. I will then go on to argue that Kant sees Hume’s tendency to slide into more radical forms of skepticism as a symptom of his failure to provide a systematic or principled account of this distinction. This failure, I argue, can be traced (according to Kant) to Hume’s impoverished, non-hylomorphic account of our faculties – which both robs Hume of the materials necessary to construct a genuinely systematic philosophy as Kant understands this, and makes it impossible for Hume to clearly conceive of what Kant calls ‘Formal Idealism.’ In this way, the failings of Hume’s account of causation are (for Kant) symptoms of more fundamental limitations within Hume’s philosophy. I close by briefly discussing the similarities between Hume and Kant’s understanding of the relationship between, first, philosophical methodology and, second, the nature of our faculties. (shrink)

BackgroundThe return of genetics and genomics research results has been a subject of ongoing global debate. Such feedback is ethically desirable to update participants on research findings particularly those deemed clinically significant. Although there is limited literature, debate continues in African on what constitutes appropriate practice regarding the return of results for genetics and genomics research. This study explored perspectives and ethical considerations of Ugandan genomics researchers regarding the return of genetics and genomics research results.MethodsThis was a qualitative study that (...) employed in-depth interviews. Thirty participants were purposively selected based on their expertise as genomics researchers in Uganda. Data were analysed through content analysis along the main themes of the study using a comprehensive thematic matrix, to identify common patterns arising from the narratives. NVivo software 12 was used to support data analysis.ResultsThe return of genetics and genomics research results was generally acceptable to researchers, and some indicated that they had previously returned individual or aggregate results to participants and communities. The main reasons cited for sharing research results with participants included their clinical utility, actionability and overall benefit to society. Ethical considerations for appropriate return of results included a need for effective community engagement, genetic counselling prior to disclosure of the results, adequate informed consent, and proper assessment of the implications of, or consequences of returning of results. However, the approaches to return of results were perceived as unstandardized due to the lack of appropriate regulatory frameworks.ConclusionsThe return of genetic and genomic research results is generally acceptable to researchers despite the lack of appropriate regulatory frameworks. Ethical considerations for return of genetics and genomics research results are highly divergent, hence the need for national ethical guidelines to appropriately regulate the practice. (shrink)

This article overviews Hume’s thoughts on the nature and the role of imagining, with an almost exclusive focus on the first book of his Treatise of Human Nature. Over the course of this text, Hume draws and discusses three important distinctions among our conscious mental episodes : between impressions and ideas ; between ideas of the memory and ideas of the imagination; and, among the ideas of the imagination, between ideas of the judgement and ideas of the fancy. I discuss (...) each distinction in turn, also in connection to contemporary views on imagining. In addition, I briefly consider Hume’s views on the imagination as a faculty aimed at the production of ideas, as well as on the role that imagining plays in the wider context of our mental lives, notably in the acquisition of modal knowledge and in the comprehension of stories and opinions that we take to be false or fictional.

As technology advances, the demand for innovative instructional materials also increases. As a result, the Department of Education urges teachers to develop instructional materials. This study was conducted at Bulusan National High School, Bulusan, Sorsogon, Philippines SY 2018-2019 which was aimed to develop gamified instructional materials in genetics that would aid in teaching and learning process of grade 12 STEM students. The developed gamified materials were collectively called the GIM in Genetics which is comprised of two parts; namely, Student’s Portfolio (...) and Gamified Lesson Plans. The GIM was anchored on the Teacher’s Guide provided by DepEd. Further, it utilized different game elements, to wit: game mechanics, badges, power cards, scoring system, levels, and leaderboards to deliver innovative teaching strategy and quality education. This paper suggests the development of various innovative teaching strategies and instructional materials as well as its utilization across different fields and subject areas. (shrink)

Prosper Lucas (1808–1885) is a unique figure in the history of psychiatric genetics. A physician-alienist, he authored one of the most important books on human genetics in the mid-19th century cited frequently by Darwin: the 1,500 page treatise—Philosophical and Physiological Treatise on Natural Heredity (1847–1850). This book contained a novel theory of the nature of inheritance and a detailed review of the heredity of a range of human traits and disorders, including various forms of insanity. Lucas postulated four forms of (...) heredity (direct, crossed, indirect, and atavistic), supported the importance of hereditary factors in insanity, accepted the inheritance of acquired characteristics, considered it important to examine both ancestors and collateral relatives, and recognized that heredity could influence both primary insanity and insanity secondary to other medical conditions. He reviewed the then available literature on most major forms of insanity including separate sections on hallucinations and suicidal monomania. The literature consisted of case reports of unusual families with high concentrations of illness. Lucas advocated for the homogeneity of transmission of forms of illness in families but recognized that—just as the form of illness could evolve within individuals over time—it could change forms when transmitted between relatives.
