Understanding the evolutionary role of environmentally induced phenotypic variation (i.e., plasticity) is an important issue in developmental evolution. A major physiological response to environmental change is cellular stress, which is counteracted by generic stress reactions detoxifying the cell. A model, stress‐induced evolutionary innovation (SIEI), whereby ancestral stress reactions and their corresponding pathways can be transformed into novel structural components of body plans, such as new cell types, is described. Previous findings suggest that the cell differentiation cascade of a cell type (...) critical to pregnancy in humans, the decidual stromal cell, evolved from a cellular stress reaction. It is hypothesized that the stress reaction in these cells was elicited ancestrally via inflammation caused by embryo attachment. The present study proposes that SIEI is a distinct form of plasticity‐based evolutionary change leading to the origin of novel structures rather than adaptive transformation of pre‐existing characters.

Heterogeneity within MDD has hampered identification of biological markers (e.g., intermediate phenotypes, IPs) that might increase risk for the disorder or reflect closer links to the genes underlying the disease process. The newer characterizations of dimensions of MDD within Research Domain Criteria (RDoC) domains may align well with the goal of defining IPs. We compare a sample of 25 individuals with MDD compared to 29 age and education matched controls in multimodal assessment. The multimodal RDoC assessment included the primary IP (...) biomarker, positron emission tomography (PET) with a selective radiotracer for 5-HT1A ([11C]WAY-100635), as well as event-related functional MRI with a Go/No-go task targeting the Cognitive Control network, neuropsychological assessment of affective perception, negative memory bias and Cognitive Control domains. There was also an exploratory genetic analysis with the serotonin transporter (5-HTTLPR) and monamine oxidase A (MAO-A) genes. In regression analyses, lower 5-HT1A binding potential (BP) in the MDD group was related to diminished engagement of the Cognitive Control network, slowed resolution of interfering cognitive stimuli, one element of Cognitive Control. In contrast, higher/normative levels of 5-HT1A BP in MDD (only) was related to a substantial memory bias toward negative information, but intact resolution of interfering cognitive stimuli and greater engagement of Cognitive Control circuitry. The serotonin transporter risk allele was associated with lower 1a BP and the corresponding imaging and cognitive IPs in MDD. Lowered 5HT 1a BP was present in half of the MDD group relative to the control group. Lowered 5HT 1a BP may represent a subtype including decreased engagement of Cognitive Control network and impaired resolution of interfering cognitive stimuli. Future investigations might link lowered 1a BP to neurobiological pathways and markers, as well as probing subtype-specific treatment targets. (shrink)

Technological advances in veterinary medicine have produced considerable progress in the diagnosis and treatment of numerous diseases in animals. At the same time, veterinarians, veterinary technicians, and owners of animals face increasingly complex situations that raise questions about goals of care and correct or reasonable courses of action. These dilemmas are frequently controversial and can generate conflicts between clients and health care providers. In many ways they resemble the ethical challenges confronted by human medicine and that spawned the creation of (...) clinical ethics committees as a mechanism to analyze, discuss, and resolve disagreements. The staff of the North Carolina State University Veterinary Hospital, a specialty academic teaching institution, wanted to investigate whether similar success could be achieved in the tertiary care veterinary setting. We discuss the background and rationale for this method, as well as the approach that was taken to create a clinical ethics committee. (shrink)

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

As part of a book symposium on Nicholas Vrousalis' Exploitation as Domination: What Makes Capitalism Unjust (2023), S.M. Love argues that only the Kantian view can justify Vrousalis’ argument for the injustice of exploitation, and gives a more detailed account of the injustice of domination within the Kantian framework.

While there are many points of opposition between the political philosophies of Marx and Kant, the two can greatly benefit from one another in various ways. Bringing the ideas of Marx and Kant together offers a promising way forward for each view. Most significantly, a powerful critique of capitalism can be developed from their combined thought: Kant’s political philosophy offers a robust idea of freedom to ground this critique, while Marx provides the nuanced understanding of social and political power structures (...) under capitalism that allows this idea of freedom to be properly applied.

The larval arms of echinoid plutei are used for locomotion and feeding. They are composed of internal calcite skeletal rods covered by an ectoderm layer bearing a ciliary band. Skeletogenesis includes an autonomous molecular differentiation program in primary mesenchyme cells (PMCs), initiated when PMCs leave the vegetal plate for the blastocoel, and a patterning of the differentiated skeletal units that requires molecular cues from the overlaying ectoderm. The arms represent a larval feature that arose in the echinoid lineage during the (...) Paleozoic and offers a subject for the study of gene co-option in the evolution of novel larval features. We isolated new molecular markers in two closely related but differently developing species, Heliocidaris tuberculata and Heliocidaris erythrogramma. We report the expression of a larval arm-associated ectoderm gene tetraspanin, as well as two new PMC markers, advillin and carbonic anhydrase. Tetraspanin localizes to the animal half of blastula stage H. tuberculata and then undergoes a restriction into the putative oral ectoderm and future location of the postoral arms, where it continues to be expressed at the leading edge of both the postoral and anterolateral arms. In H. erythrogramma, its expression initiates in the animal half of blastulae and expands over the entire ectoderm from gastrulation onward. Advillin and carbonic anhydrase are upregulated in the PMCs postgastrulation and localized to the leading edge of the growing larval arms of H. tuberculata but do not exhibit coordinated expression in H. erythrogramma larvae. The tight spatiotemporal regulation of these genes in H. tuberculata along with other ontogenetic and phylogenetic evidence suggest that pluteus arms are novel larval organs, distinguishable from the processes of skeletogenesis per se. The dissociation of expression control in H. erythrogramma suggest that coordinate gene expression in H. tuberculata evolved as part of the evolution of pluteus arms, and is not required for larval or adult development.

Socialism has long been thought by many to be the enemy of freedom. Here, I argue that in order to understand the relationship between socialism and freedom, we must have a better idea both of what socialism is and of what it is to have a right to freedom. To start, I argue that the right to freedom is best understood as a right to direct one’s own will in the world consistently with the rights of others to do the (...) same. This Kantian conception of the right to freedom is importantly different from the ubiquitous conception of freedom as negative liberty: with this Kantian conception, one’s right to freedom is limited to directing one’s own will and does not include a right to direct the wills of others. I then argue that socialism, like the right to freedom, is often misunderstood: today, socialists often argue for robustly democratic forms of socialism that are far from the autocratic so-called “socialist” regimes of the last century. With a better understanding of both socialism and the right to freedom, we can see that the right to freedom is indeed compatible with a robustly democratic form of socialism. (shrink)

The article argues that Kant’s argument for ownership entails a standard of meaningful use by which property regimes can be evaluated: a regime must make it possible for usable objects to be meaningfully used. A particular form of fully communal ownership can satisfy this standard. Further, this form of communal ownership is compatible with Kantian freedom more broadly. I conclude that, if this is so, there is a great deal of space for further consideration of the rightfulness of diverse regimes (...) of ownership and exchange within a Kantian framework. (shrink)

The origin of marine invertebrate larvae has been an area of controversy in developmental evolution for over a century. Here, we address the question of whether a pelagic “larval” or benthic “adult” morphology originated first in metazoan lineages by testing the hypothesis that particular gene co-option patterns will be associated with the origin of feeding, indirect developing larval forms. Empirical evidence bearing on this hypothesis is derivable from gene expression studies of the sea urchin larval gut of two closely related (...) but differently developing congenerics, Heliocidaris tuberculata (feeding indirect-developing larva) and H. erythrogramma (nonfeeding direct developer), given two subsidiary hypotheses. (1) If larval gut gene expression in H. tuberculata was co-opted from an ancestral adult expression pattern, then the gut expression pattern will remain in adult H. erythrogramma despite its direct development. (2) Genes expressed in the larval gut of H. tuberculata will not have a coordinated expression pattern in H. erythrogramma larvae due to loss of a functional gut. Five structural genes expressed in the invaginating archenteron of H. tuberculata during gastrulation exhibit substantially different expression patterns in H. erythrogramma with only one remaining endoderm specific. Expression of these genes in the adult of H. erythrogramma and larval gut of H. tuberculata, but not in H. erythrogramma larval endoderm, supports the hypothesis that they first played roles in the formation of adult structures and were subsequently recruited into larval ontogeny during the origin and evolution of feeding planktotrophic deuterostome larvae.

An incomplete science begets imperfect models. Nevertheless, the target article advocates for jettisoning deep-learning models with some competency in object recognition for toy models evaluated against a checklist of laboratory findings; an approach which evokes Alan Newell's 20 questions critique. We believe their approach risks incoherency and neglects the most basic test; can the model perform its intended task.

The star-nosed mole is aptly named. Its distinctive snout consists of 22 tendrils ringing a pair of nostrils and, from some angles, the entire setup resembles a misshapen star. The tendrils are fleshy and look a bit like fingers, and, like fingers, they have a certain dexterity. But why? Why does the mole have such a singular appendage as opposed to something more ordinary? What is the function or purpose of this bizarre structure? From the dedicated work of Ken Catania, (...) of Vanderbilt University, and colleagues, it appears that the appendage facilitates rapid handling of small prey items, making it advantageous for an organism whose diet consists of tiny invertebrates. We might therefore hazard that this feature arose evolutionarily because it conferred this benefit. But the matter is difficult to resolve, because current utility does not permit a straightforward inference of a reason for existence. -/- A correction has been published: BioScience, Volume 72, Issue 7, July 2022, Page 708.

Este ensayo analiza las fuentes de origen medieval y moderno sobre la historia de Y^arba en el Ima-mato rustamí en un intento de aclarar la naturaleza de la relación histórica e historiográfica entre ellos. Se empieza por discutir las fuentes primarias y secundarias disponibles, incluyendo los retos historiográficos que plantean y se presenta a continuación un análisis de las evidencias textuales y arqueológicas que conectan a los rustamíes con Y^arba. Se intenta después sintetizar las piezas dispersas de la evidencia disponible (...) en el registro histórico con el fin de presentar una imagen más clara de Y^arba durante el período rustamí. Con base en esta evidencia textual y arqueológica, se argumentará que Y^arba era hogar de una comunidad iba-dí independiente del gobierno en Ta-hert durante la mayor parte (si no en su totalidad) de la existencia del Ima-mato, distinguiendo así la isla de los alrededores del Y^arid (en el sur de Túnez), partes de la Ifri-qiya Aglabí y el Y^abal Nafu-sa.

ObjectiveParenting sensitivity and mutual parent-child attunement are key features of environments that support children’s learning and development. To-date, observational measures of these constructs have focused on children aged 2–6 years and are less relevant to the more sophisticated developmental skills of children aged 7–8 years, despite parenting being equally important at these ages. We undertook a rigorous process to adapt an existing observational measure for 7–8-year-old children and their parents. This paper aimed to: describe a protocol for adapting an existing (...) framework for rating parent-child interactions, determine variations in parents’ sensitive responding and parent-child mutual attunement by family demographics, and evaluate the psychometric properties of the newly developed measure.MethodParent-child dyads completed one home visit, including a free-play observation and parent questionnaire. Dyads were provided with three toy sets: LEGO® Classic Box, Classic Jenga®, and animal cards. The Coding of Attachment-Related Parenting was adapted for use with 7–8-year-old children, and rating procedures were streamlined for reliable use by non-clinician/student raters, producing the SCARP:7–8 Years. Trained staff rated video-recorded observations on 11 behaviors across two domains.ResultsData were available for 596 dyads. Consistently strong inter-rater agreement on the 11 observed behaviors was achieved across the 10-week rating period. Average ICCs were 0.77 for sensitive responding and 0.84 for positive mutuality. These domains were found to be related but distinct constructs. For both domains, average ratings were strongly associated with the main toy used during the observation. Adjusted multivariate linear regression models revealed that less sensitive responding was associated with younger parent, male parent, non-English speaking background, and greater neighborhood disadvantage. Construct validity was demonstrated using six parent-reported psychosocial and parenting measures.ConclusionThe SCARP: 7–8 Years shows promise as a reliable and valid measure of parent-child interaction in the early school years. Toy selection for direct observation should be considered carefully in research and practice settings. (shrink)

Loving-kindness meditation (LKM) is a popular contemplative mental practice. Its purpose is to cultivate feelings of compassion, love, and prosocial motivation, typically through inner visual imagery and benevolent intentions. Previous studies have revealed evidence for various constructive effects of LKM. It remains an open question, however, whether the effects of LKM are exclusively positive in all practitioners. To tackle this question, we collected 55 microphenomenological interviews (MpIs) reflecting subjective experiences during LKM. Furthermore, we obtained psychological and biological (oxytocin, cortisol) (...) inter-individual difference measures during a nine-month, longitudinal, mental training study. LKM was predominantly described in positive affective terms and associated with cortisol decrease in accordance with the natural diurnal decline, which reflects its generally non-stressful nature. However, five participants reported experiences such as panic, sadness, and fear. Emotional challenge, as indicated by negative word use during MpIs, was linked to lower scores of self-kindness and higher scores of selfcompassionate mindfulness. (shrink)

Historically, entities with a vested interest in a product that critics have suggested is harmful have consistently used research to back their claims that the product is safe. Prominent examples are: tobacco, lead, bisphenol A, and atrazine.

In parallel to other historical debates, recent studies examining a possible relationship between (...) mercury exposure and autism spectrum disorder show a similar dichotomy. Studies sponsored and supported by industry or entities with an apparent conflict of interest have most often shown no evidence of harm or no “consistent” evidence of harm, while studies without such affiliations report positive evidence of a Hg/autism association. The potentially causal relationship between Hg exposure and ASD differs from other toxic products since there is a broad coalition of entities for whom a conflict of interest arises. These include influential governmental public health entities, the pharmaceutical industry, and even the coal burning industry. This review includes a systematic literature search of original studies on the potential relationship between Hg and ASD from 1999 to date, finding that of the studies with public health and/or industry affiliation, 86 % reported no relationship between Hg and ASD. However, among studies without public health and/or industry affiliation, only 19 % find no relationship between Hg and ASD.

It also argues that Kierkegaard's philosophical, literary, and theological explorations reveal that (...) love is filled with paradox. (shrink)

This paper argues that, by construing emotion as epistemologically subversive, the Western tradition has tended to obscure the vital role of emotion in the construction of knowledge.

It then moves on to show how the myth of dispassionate investigation has functioned historically to undermine the epistemic authority of women as well as other social (...) groups associated culturally with emotion. Finally, the paper sketches some ways in which the emotions of underclass groups, especially women, may contribute to the development of a critical social theory. (shrink)

Modern commentators like Allen Wood have noted that for Kant there “is a basic tension in human nature between loving people and respecting them.” Love is a threat to pure morality insofar as love is an empirical inclination and any will determined by such an inclination is unfree. In this paper, I begin by exploring why Kant thinks that love is a threat to moral freedom. Drawing on the insights of Dietrich von Hildebrand, I propose instead an (...) analysis of love as “value-response.” I argue that a more complete phenomenological analysis of the nature of human affectivity (as fundamentally intentional and responsive) exposes a serious defect in Kant’s moral psychology, particularly his unreasonable denial of the compatibility of higher-order affectivity and human freedom. Drawing on von Hildebrand’s notion of “cooperative freedom,” I argue that not only is a higher-order spiritual affectivity compatible with freedom and morality, but it is essential to it. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:M. C. Dillon LOVE IN WOMEN IN LOVE: A PHENOMENOLOGICAL ANALYSIS Despite his sexism, his turgid prose, and his antiquated social conscience, Lawrence is on every bookshelf. This is not merely because of the vicarious erotic entertainment to be found in the saga of John Thomas and Lady Jane, but because Lawrence remains a major guru of romance. We take him seriously, look to him for guidance, (...) measure ourselves against Ursula and Birkin. If he is on our shelves—and his thoughts not far from our pillows—then his ideas starid in need of scrutiny. Women in Love is as much a treatise as a novel: we witness more talking about than making of love. The agon of ideas engulfs the agon of flesh. Hence, the book suits the present purpose. It cannot be taken as Lawrence's definitive statement on love—later works, notably Lady Chatterly's Lover, move in different directions—but it is his most philosophical treatment and, I think, most clearly expresses his conceptual framework, the parameters which define and limit his thinking. What he says about love in Women in Love may therefore illumine his depictions of the behavior of lovers in other works. Lawrence is a romantic. In the popular sense of the word he is one who makes of romance or erotic adventure a dominant life value. Lawrence is also a romantic in another sense insofar as he takes the transcendence or unattainability of the other as essential to the project of loving. These two senses are conceptually compatible but existentially in conflict. That is, if one's major undertaking in life is to seek erotic satisfaction, and if one desires only so long as the object is beyond reach, then one has established the groundwork for continual frustration. This, I will try to show, is what Lawrence has done. I Many writers have tried to bring the ideas implicitly present in and constitutive of romantic love to the level of explicit reflective awareness. 190 M.C.Dillon191 The most successful treatment I know is given by a writer who did not know—or at least did not say—that he was writing about romantic love. Sartre purports to reveal the inner structures of love itself—the unqualified, unrestricted essence of love. As I have tried to show elsewhere,1 he fails at this. But he succeeds admirably in unveiling the inner contradictions of romantic love. Our project here is to draw upon Sartre's insights: first, to develop a conception of romantic love, and then to discern the model of Eros which informs Women in Love. The key idea in romantic love is transcendence. Something is transcendent when it is beyond me, when I cannot adequately prehend it conceptually or master it with my will. The role of transcendence in romantic love is demonstrated clearly in Denis de Rougemont's book on Love in the Western World.2 There he shows that Tristan's passion for Iseult is directly proportional to her distance from him: he is increasingly attracted as she becomes further removed. On the other hand, when through various deeds of gallantry and subterfuge, he succeeds in winning her to his side, he loses interest and must create circumstances which put her again beyond his reach. The culmination of romantic love, according to de Rougemont, is death—it sets the other absolutely beyond reach. It also arrests and preserves at their apices the youth and beauty of the lovers and the intensity of the erotic relationship. It is, I believe, this complex of ideas that led Kierkegaard to this cynical reflection on the nature of romantic love: "When two beings fall in love with one another and begin to suspect that they were made for each other, it is time to have the courage to break it off; for by going on they have everything to lose and nothing to gain."3 The same idea, qualified by increased optimism, underlies Stendhal's notion of crystallization in his book On Love.* Love is predicated on the attribution of perfection to the beloved. Just as a plain bough emerges from the salt-saturated waters of the Salzburg mines encrusted with beautiful crystals... (shrink)

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

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

This paper offers an analysis of work on human development in evolutionary anthropology from a Thomist perspective. I show that both fields view care for others as fundamental to human nature and interpret cooperative breeding as expression of the virtue of charity. I begin with an analysis of different approaches to the relationship between evolutionary anthropology and moral theory. I argue that ethical naturalism is the approach best suited to interdisciplinary dialogue, since it holds that natural facts are useful for (...) moral theory but do not encompass it. This forms the basis for a Thomist analysis of some key features of human evolution including bipedalism, higher encephalisation and extended childhood. In each case I explain how these parts of our nature contributed to the evolution of modern humans, and how each is reliant upon communal care. Finally, I offer three observations on these facts from a Thomist perspective. Firstly, that a good human life necessarily involves caring for others and being cared for ourselves. Secondly, that this is exemplified in the virtue of charity, which is the ground of all virtue. Finally, that the need for such care shows that human flourishing cannot be attained without divine aid. (shrink)

Ferreira also argues that Works of Love bears on issues peculiar (...) to a religious ethic, such as the role of God as "middle term," and the possibility of preserving the aesthetic dimensions of love in a religious ethic of relation.
