This article extends the Humean example of evolutionary stakeholder theory introduced in Kline and McDermott (2019). In that article, it was established that the Cost of Service Regulation (COSR) rules created by regulatory commissions, courts, and legislation was an example of evolutionary stakeholder theory. Ultimately, the Supreme Court decision in the Hope Natural Gas case established that it was not the method, but the result reach that was important. If the result reach balanced the interests of stakeholders then the outcome was just and reasonable. Kline and McDermott (2019) also established that the COSR process was rather robust in terms of stakeholder participation. The purpose of this article is to extend the analysis to examine one of the most turbulent periods in COSR's history: the Post‐OPEC oil crisis of the 1970s–1980s. The effects of this period called into question the efficacy of the COSR process and led, as evolutionary stakeholder theory predicts, to a series of engagements by stakeholders to modify the rules of the process to achieve a better balance in the publics' interest. While adjudicatory in nature, the COSR process enabled cooperative solutions to redress the imbalances created by the OPEC oil shocks, improvements in information gathering, processing and decision‐making were all products of the evolutionary stakeholder process that regulators engaged in with stakeholders.

In the nematode Caenorhabditis elegans, loss of function of many genes leads to increases in lifespan, sometimes of a very large magnitude. Could this reflect the occurrence of programmed death that, like apoptosis of cells, promotes fitness? The notion that programmed death evolves as a mechanism to remove worn out, old individuals in order to increase food availability for kin is not supported by classic evolutionary theory for most species. However, it may apply in organisms with colonies of closely related individuals such as C. elegans in which largely clonal populations subsist on spatially limited food patches. Here, we ask whether food competition between nonreproductive adults and their clonal progeny could favor programmed death by using an in silico model of C. elegans. Colony fitness was estimated as yield of dauer larva propagules from a limited food patch. Simulations showed that not only shorter lifespan but also shorter reproductive span and reduced adult feeding rate can increase colony fitness, potentially by reducing futile food consumption. Early adult death was particularly beneficial when adult food consumption rate was high. These results imply that programmed, adaptive death could promote colony fitness in C. elegans through a consumer sacrifice mechanism. Thus, C. elegans lifespan may be limited not by aging in the usual sense but rather by apoptosis‐like programmed death. [ABSTRACT FROM AUTHOR]

Multivalent chemical fuel driven transient assembly plays a critical role in biological processes. This inspires chemists to design synthetic systems having transient and dynamic functionalities. However, a detailed understanding about the temporal evolution of each of the intermediate species in a multi‐step assembly under dissipative conditions has not yet been explored. Herein, we have shown under dissipative conditions, how the strength of dissipation can modulate the compositional behavior of each of the intermediate species during their survival period by using kinetic modeling (with Python). We have observed that the appearance and disappearance of intermediates (formed either at the first or penultimate assembly step) are highly non‐linear in nature, and it is possible to trap any of the desired intermediates or a mixture of them of certain compositions at a definite time interval simply by tuning the strength of dissipation.

A recent evolutionary theory of female sexual fluidity suggests that women may not have sexual orientations in the same sense that men do, and that women's apparent sexual orientation may instead be a byproduct of their sociosexual orientation. One developmental factor that has consistently been shown to influence sociosexual orientation is father absence in childhood. Consistent with the prediction of the theory, the analyses of the National Longitudinal Study of Adolescent to Adult Health (Add Health) data show that father absence significantly increases women's, but not men's, same‐sex sexuality in adulthood, whether it is measured by self identity, sexual behaviour, or romantic attraction. Further consistent with the theory, the association between father absence and same‐sex sexuality in women is entirely mediated by their sociosexual orientation. [ABSTRACT FROM AUTHOR]

No God, no human freedom, no human freedom, no evil; if you believe in the existence of evil, you must believe in God! Also, while Davis could attribute human evil to free human choice, Helm must explain why God has organized the world in a way that guaranties the existence of human evil. In response, Davis complains that Helm's Calvinist doctrine does not lend humans enough freedom and responsibility to be truly evil. [Extracted from the article]

In many species, it is common for animals to have multiple signals within one channel of communication. Multiple signals may, however, be inefficient if they are redundant in nature. Identifying the functional significance of these multiple signals is therefore important if we are to understand the evolution of such elaborated behaviours. We proposed to identify the roles of movement‐based multiple signals in a model animal system. Male fiddler crabs wave their sexually dimorphic enlarged claw during social interactions. Some species present multiple signals, where the level of complexity of the movement changes. Males of Austruca mjoebergi can perform a double wave consisting of a high‐ followed by a low‐elevation lifting of the claw, or a single wave consisting of the high‐elevation movement alone. We first investigated structural differences between the double and single wave types, and found that single waves were lower in elevation than double waves. We then explored the adaptive meaning of the wave types by manipulating the social context in which males wave. We found that double waves were given in all contexts and in higher proportions at long distances, suggesting a function of broadcasting male location. Single waves, on the other hand, were mainly given at close range and in the presence of conspecifics, suggesting intraspecific communication. Female presence elicited the highest number and proportion of single waves, a likely result of a female preference for higher wave rates. Finally, we point out that there is an element of interaction between wave types that deserves future attention. This paper is an important contribution to expand our understanding of the adaptive meaning of multiple visual signals and help reach a unified theory of their evolution. [ABSTRACT FROM AUTHOR]

Pulsating fracturing, as a new technology for unconventional oil and gas exploration, enables to enhance stimulated reservoir volume (SRV) effectively, which further helps to improve well performance. It is of great importance for the evaluation of fracturing performance and optimization of fracturing parameters by accurately calculating variables from formation impairment during pulsating fracturing treatment. Based on the principle of conservation of energy, a novel theoretical model describing the evolution of rock damage was proposed by analyzing energy evolutionary characteristics from the hysteresis loop of rock stress‐strain curve while the treatment. This model was in a good agreement with experimental data. In this paper, our study indicates that the rock damage is caused by the accumulation of damage in each cyclic loading and unloading process during pulsating fracturing. Moreover, the cumulative rock damage would increase with the increment of the number of cyclic loading and unloading. Conversely, the rock strength is negatively correlated with cyclic number. The cumulative damage variable approximates to one as the rock breaks. Additionally, the frequency and the stress level of pulsating fracturing have an obvious impact on the evolution of rock damage. The optimization of these parameters can help to accelerate the rock damage and reduce the corresponding rock strength. The speed of rock damage can be accelerated with the enhancement of the stress level at the later period of the step loading, which facilitates the increment of cumulative damage variable. Our new model provides a guideline for predicting the initial rock damage during pulsating treatment. [ABSTRACT FROM AUTHOR]

When considering the persuasive characteristics and prospective influences of Darwin‐skeptic mass media, uncertainties remain about how to reciprocally promote evolutionary theory to skeptical audiences. This study aims to improve evolution advocacy by translating some of the most successful methods of science endorsement to Evolution Wars contexts. In particular, strategies used to address vaccine hesitancies and enhance immunization uptake policies are reinterpreted for those seeking to improve pro‐evolution communications to religious publics. What results are three recommendation categories described as General Guiding Principles, Proximate Interventions, and Auxiliary Interventions. [ABSTRACT FROM AUTHOR]

This essay introduces, for theological consideration, some recent work in the field of cultural evolutionary theory, specifically the kin‐influence hypothesis. This theory holds that, following the beginnings of industrialization and economic growth, a nation's fertility rate commences a decline, which is further abetted by the consequent and increasing imbalance in the relative influence of kin versus nonkin influences on individuals in favor of the latter. It is further proposed that this process is itself a major independent factor in the emergence of many of the features of what is called modernity, among which is that of secularization. Extending further this work, I argue that, given the historic alignment of family and religious values in Christian nations, a loss of religious belief and practice is, at least in part, the spill over effect of the opposing influence of values emerging from ever more dominant nonfamily social interaction. I conclude with some reflections on possible theological implications. [ABSTRACT FROM AUTHOR]

The concept of continuous creation is now widely used in the context of reflections on the dialogue between science and religion. The first part of this research work seeks to understand its meaning through a twofold elaboration: (1) the historical setting of the three philosophical trends in which this concept was developed: scholastic (conservation), Cartesian (conservation through repetition of the creative act at each instant), and dynamic (interpreting the emergence of radical and contingent novelty in nature as a sign of the continuity of creation); (2) a philosophical and theological critique of the concept of continuous creation regarding the question of the relationship between change and creation, in the light of its highly polymorphous contemporary use, and, in opposition, its absence within the Catholic Magisterium. This work opens the field a further step toward reflection on a renewed concept of continuous creation. [ABSTRACT FROM AUTHOR]

The theory of sexual selection is the most widely accepted theory explaining the evolution of mating systems and secondary sexual characters. Polygyny is the most common mating system in mammals, and there is a strong correlation between the degree of polygyny and the degree of sexual size dimorphism skewed towards males. Sexual selection theory posits that polygyny in mammals has evolved through direct, precopulatory, intrasexual selection in males, and that sexual size dimorphism is a result of male competition for mates. New results that are being obtained with the use of molecular techniques and with comparative phylogenetic methods do not appear to support predictions from this classical model in full. In this article, an expansion of the classical model is presented that combines the effects of at least four forms of selection: natural, precopulatory intrasexual, postcopulatory intrasexual, and intersexual selection. This mixed model consists of an initial phase in which natural selection operates on body size, followed by a second phase dominated by sexual selection and involving increases in sexual dimorphism and coercive behaviour of males towards females. Sexual harassment induces female aggregation, thus creating social potential for polygyny. Males compete for access to the groups of females, following two possible evolutionary scenarios, directional or equilibrium sexual selection, both producing similar behavioural polygyny, but with differences in the intensity of intra‐male precopulatory sexual selection. Predictions of the mixed model are as follows: 1) polygyny can exist without high variance in male reproductive success (a fundamental requirement in the classical model); 2) extra‐group fertilisation can be common; 3) sexual size dimorphism evolved prior to polygyny; 4) sexual coercion is widespread; and 5) females reduce levels of sexual coercion by joining groups.

Until recently, senescence was assumed to be a universal phenomenon. Evolutionary theories of senescence predict that no organism may escape the physiological decline that results in an increase in mortality risk and/or decline in fertility with age. However, evidence both in animals and plants has emerged in the last decade defying such predictions. Researchers are currently seeking mechanistic explanations for the observed variation in ageing trajectories.We argue that the historical view on the inevitability of senescence is due, in part, to the development of its classical theories, which targeted primarily unitary organisms. In unitary species, the integration of resources and functions is high, and adult size is determined. In contrast, the architecture of modular organisms is indeterminate and built upon repeated modules. The isolation of mortality risk in species like hydra (Hydra spp.) or creosote brush Larrea tridentata may explain their null or even negative senescence.Caleb Finch hypothesized three decades ago that species with the ability to compartmentalize risk may escape senescence. Here, we first review the evidence on organisms that slow down or even avoid senescence in the context of their architecture, along a continuum of unitarity‐modularity. Then, we use open‐access databases to comparatively analyse various moments of senescence and link longevity to the degree of anatomical modularity. Our analysis compares the pace of senescence across 138 plants and 151 animals, and the shape of senescence across a subset of these. Our comparative analysis reveals that plant species that are more modular do indeed tend to escape from senescence more often than those that are unitary. The role of modularity in animal senescence is less clear.In light of novel support for Finch's hypothesis across a large diversity of plant species, and with less conclusive findings in animals, we identify new research directions. We highlight the opportunities related to age‐dependent mortality factors. Other areas for further research include the role of modularity in relation to endocrine actions, and the costs of modular anatomies. [ABSTRACT FROM AUTHOR]

The relation of developmental plasticity to evolutionary diversification is a key component of evolutionary theory involving developmental bias, but the basis of the relationship varies among traits and among taxa. Here I review some scenarios of how structural integration during early organogenesis could influence this relationship. When condensations are highly integrated and dependent on each other during early organogenesis, both plasticity and evolution are restricted, for example size proportions in molar tooth rows and phalanges within a digit. When similar condensations develop and remain separate (in tracheal cartilages and feather buds), they show high levels of variation and diversity in number but not in shape and size, at least at early stages. When non‐similar structures form separately and then integrate while still undergoing patterning, high levels of plasticity (in number, size, shape; in rib uncinate processes) or new dimensions of ecologically‐significant variation (cusp offset, in mammal teeth) are seen. Although each of these structural integration scenarios is unique, the modulation of evolvability is detectable and informative. Parsing the influence of structural integration at these developmental levels, rather than later‐stage structural correlations or only through genetic covariation, may be necessary to advance understanding of evolvability of the phenotype.

Studies of the charter sector typically compare charters and traditional public schools at a point in time. These comparisons are potentially misleading, because many charter‐related reforms require time to generate results. We study quality dynamics among charter schools in the State of Texas from 2001 to 2011. School quality in the charter sector was initially highly variable and on average lower than in traditional public schools. However, exits, improvement of existing charter schools, and higher quality of new entrants increased charter effectiveness relative to traditional public schools despite an acceleration in the rate of sector expansion in the latter half of the decade. We present evidence that reduced student mobility and an increased share of charters adhering to No‐Excuses‐style curricula contribute to these improvements. Although selection into charter schools becomes more favourable over time in terms of prior achievement and behaviour, such compositional improvements appear to contribute little to the charter sector gains. Moreover, accounting for composition in terms of prior achievement and behaviour has only a small effect on estimates of the higher average quality of No Excuses schools. [ABSTRACT FROM AUTHOR]

To 'Darwinize' a debunking argument is to broaden and thereby strengthen it in ways inspired by Charles Darwin. It is to employ Darwinian strategies that converge on the conclusion that certain putative phenomena – the reality of stance‐independent moral properties, for instance – are illusory or epistemically problematic for animals like us. The aim of this essay is to defend one such strategy and illustrate its power relative to most evolutionary debunking arguments currently on offer. [ABSTRACT FROM AUTHOR]

This special issue of I Ratio i focusses on a variety of issues in evolutionary ethics. As Paul Farber has argued in his masterful historical overview of the subject, the beginnings of evolutionary ethics can be traced to Charles Darwin (Farber, [3], p. 7). As Farber explains, according to E.O. Wilson, 'biology can explain in evolutionary terms those moral intuitions that philosophers have so desperately tried to justify' (Farber, [3], p. 151). So it seems that after all, 'sociobiology has not increased the plausibility of contemporary versions of evolutionary ethics over its earlier versions' (Farber, [3], p. 166).

Over the past four decades, the paradox of fiction has sparked considerable debate among philosophers. Unfortunately, the most promising solution to this puzzle, thought theory, currently earns its plausibility by way of intuition rather than evidence. I aim to address this by updating thought theory in light of recent empirical findings on affect. I will draw upon a wide range of scientific research—on the cognitive mechanisms driving emotion, the role of affect in counterfactual mind wandering and prospection, and the evolutionary function of affect—to substantiate the claim that fictions can give rise to both real and rational emotional states.

Considering the relatively high heritability of schizophrenia and the fact that it significantly reduces the reproductive fitness of affected individuals, it is not clear how the disorder is still maintained in human populations at a disproportionally high prevalence. Many theories propose that the disorder is a result of a trade‐off between costs and benefits of the evolution of exclusively human adaptations. There have also been suggestions that schizophrenia risk alleles are accompanied with increase in fitness of affected persons or their relatives in both past and current social contexts. The discoveries of novel schizophrenia‐related genes and the advancements in comparative genomics (especially comparisons of the human genome and the genomes of related species, such as chimpanzees and extinct hominids) have finally made certain evolutionary theories testable. In this paper, we review the current understanding of the genetics of schizophrenia, the basic principles of evolution that complement our understanding of the subject, and the latest genetic studies that examine long‐standing evolutionary theories of schizophrenia using novel methodologies and data. We find that the origin of schizophrenia is complex and likely governed by different evolutionary mechanisms that are not mutually exclusive. Furthermore, the most recent evidence implies that schizophrenia cannot be comprehended as a trait that has elevated fitness in human evolutionary lineage, but has been a mildly deleterious by‐product of specific patterns of the evolution of the human brain. In other words, novel findings do not support previous hypotheses stating that schizophrenia risk genes have an evolutionary advantage. [ABSTRACT FROM AUTHOR]

Previous research has noted one's knowledge of and attitudes toward the theory of evolution is negatively predicted by one's political ideology, specifically how conservative the individual identifies, and positively predicted by one's level rational thinking. The present research expands on this past research by examining the roles of political conservatism and rational thinking in predicting one's reported relevance of evolutionary theory in a multi‐study design. In Study 1, a sample of undergraduate college students (N = 198) completed a survey with measures of conservatism, rational and intuitive thinking styles, including both engagement and ability, and attitudes toward the relevance of evolutionary theory. A multiple mediator model revealed that conservatism was a negative predictor rational engagement, rational engagement was a positive predictor of relevance of evolution, and the indirect effect of conservatism on relevance of evolution through rational engagement was significant. In Study 2, a new sample of college students (N = 146) completed an experiment where rational engagement was manipulated. Conservatism negatively predicted relevance of evolution for individuals who were not primed to engage in rational thought and were below average in rational ability. Conversely, conservatism was not a significant predictor of relevance of evolution for individuals who were primed to engage in rational thought, and who had below average rational ability scores. These results suggest that when individuals are lower in rational ability, priming for rational engagement may be effective at buffering the effect of conservatism on one's reported relevance of evolution. Thus, examining additional procedures for increasing one's rational engagement may be useful for educators and researchers interested in reducing the effects of political ideology on one's knowledge of and attitudes toward evolution.

John Tyler Bonner's call to re‐evaluate evolutionary theory in light of major transitions in life on Earth (e.g., from the first origins of microbial life to the evolution of sex, and the origins of multicellularity) resonate with recent discoveries on epigenetics and the concept of the hologenome. Current studies of genome evolution often mistakenly focus only on the inheritance of DNA between parent and offspring. These are in line with the widely accepted Neo‐Darwinian framework that pairs Mendelian genetics with an emphasis on natural selection as explanations for the evolution of biodiversity on Earth. Increasing evidence for widespread symbioses complicates this narrative, as is seen in Scott Gilbert's discussion of the concept of the holobiont in this series: Organisms across the tree of life coexist with substantial influence on one another through endosymbiosis, symbioses, and host‐associated microbiomes. The holobiont theory, coupled with observations from molecular studies, also requires us to understand genomes in a new way—by considering the interactions underlain by the genome of a host plus its associated microbes, a conglomerate entity referred to as the hologenome. We argue that the complex patterns of inheritance of these genomes coupled with the influence of symbionts on host gene expression make the concept of the hologenome an epigenetic phenomenon. We further argue that the aspects of the hologenome challenge of the modern evolutionary synthesis, which requires updating to remain consistent with Darwin's intent of providing natural laws that underlie the evolution of life on Earth. Research Highlights: Hologenomes, an integration between host and symbiont gene functions, exist at varying levels of intimacy, and exemplify the epigenetic impacts of symbiosis. Analysis of the consequences of hologenomes allows us to re‐examine aspects of evolutionary theory. [ABSTRACT FROM AUTHOR]

Intraspecific variation is at the core of evolutionary theory, and yet, from an ecological perspective, we have few robust expectations for how this variation should affect the dynamics of large communities. Here, by adapting an approach from evolutionary game theory, we show that the incorporation of phenotypic variability into competitive networks dramatically alters the dynamics across ecological timescales, stabilising the systems and buffering the communities against demographic perturbations. The beneficial effects of phenotypic variability are strongest when there are substantial differences among phenotypes and when phenotypes are inherited with moderately high fidelity; yet even low levels of variation lead to significant increases in diversity, stability, and robustness. By identifying a simple and ubiquitous stabilising force in competitive communities, this work contributes to our core understanding of how biological diversity is maintained in natural systems.

The use of activated factor VII (FVIIa) for the treatment of bleeding events in haemophilia patients with inhibitors was first reported over 30 years ago. Since then clinical trials, registries, case series, real‐world experience and an understanding of its mechanism of action have transformed what was originally a scientific curiosity into one of the major treatments for inhibitor patients, with innovative therapeutic regimens, dose optimization and individualized care now widely practiced. Given current understanding and use, it might be easy to forget the years of clinical research that led up to this point; in this review, we lay out changes based on broad eras of rFVIIa use. These eras cover the original uncertainty associated with dosing, efficacy and safety; the transformation of care ushered in with its widespread use; and the optimization and individualization of patient care and the importance of specialized support provided by haemophilia treatment centres. Today with the introduction of novel prophylactic agents such as emicizumab, we once again find ourselves dealing with the uncertainties of how best to utilize rFVIIa and newer investigational variants such as marzeptacog alfa and eptacog beta; we hope that the experiences of the past three decades will serve as a guide for this new era of care.

It is usually thought that synchronicity, characterised as 'meaningful coincidence', is therefore understandable in relation to the concept of 'meaning'. I will explore the largely unhelpful symbiotic relationship between 'coincidence' and 'meaning' by comparing synchronicity with synchoricity - coincidence in space rather than time. These two concepts are often mixed together and I will attempt to describe a 'pure' synchronicity in order to sharpen our sense of how meaning is felt to arise from coincidence. It will then be suggested that the standard concept of synchronicity is mostly psychologically irrelevant and, when adjusted to remove elements which are explained quite naturally by evolutionary theory, we are left with a concept which has implications both for the metaphysical foundations of Analytical Psychology and the individualistic emphasis one commonly finds in the field.

Ageing is ubiquitous to all organisms, but ageing does not always mean senescence. Counter to most evolutionary theories of ageing, the patterns of mortality and reproduction may remain unchanged or improve with age, as well as deteriorate. Describing this diversity presents a challenge to eco‐evolutionary demography. The pace–shape framework of mortality tackled this challenge to qualify and quantify orthogonal components of ageing patterns in mortality. Here, we extend this framework to fertility.Analogous to the logic of the mortality framework, we define a perspective, a framework and novel methods for the pace and shape of fertility. These distinguish between orthogonal components of time‐scale (pace) and distribution (shape) of reproduction over adult life span.Our pace and shape framework mirrors that of mortality, through a shift of perspective from the mother giving birth, to the offspring being born. Our new measures overcome many problems associated with measuring natural fertility trajectories, have both a clear biological and mathematical interpretation, can be intuitively visualized and satisfy and extend important conditions of the pace–shape paradigm.A comprehensive framework of fertility pace–shape facilitates ecological and evolutionary research addressing interactions and trade‐offs between components of birth and death patterns, across the whole tree of life. The burgeoning emergence of large comparative demographic data sources across wide environmental, geographical, temporal and phylogenetic ranges, combined with pace–shape measures, opens the door to comparative analyses of ageing which were never possible before.

A large body of research has examined students' conceptions of evolution and their relationships to acceptance of evolution. Proficiency in statistical and probabilistic reasoning has long been considered to be an essential feature of evolutionary reasoning, yet almost no empirical work has explored these putative connections. The RaPro instruments have recently been developed to measure statistical reasoning in the contexts of mathematics (RaProMath) and evolution (RaProEvo). Our study provides additional validation of these instruments using Rasch analysis and quantifies the contribution of statistical reasoning to both understanding and accepting evolution. We recruited a large sample (N = 564) of undergraduate students enrolled in an introductory biology course at a large public research university in the United States. Students completed a suite of published instruments that assessed statistical reasoning, evolutionary understanding, and evolutionary acceptance. Our findings indicate that validity inferences derived from RaPro scores generalized to the new sample, and that proficiency in statistical reasoning explained 28% of the variance in evolutionary knowledge and 19% of the variation in evolutionary acceptance. The inclusion of demographic variables into the model significantly increased the explained variance in acceptance. Notably, the variance in evolution acceptance explained by statistical reasoning was comparable to that of thinking dispositions or evolutionary knowledge reported in the literature. This work provides the first large‐scale evidence of the role of statistical reasoning in evolutionary knowledge and acceptance and motivates future work to explore how statistical literacy should be integrated into evolution education efforts.

Complex phenotypes result from developmental processes integrating genetic, epigenetic, and environmental information. Although changing environments combine several signals that may induce multitrait plastic responses, literature often decodes developmental plasticity into single trait variation as a function of isolated environmental signals. To address the multivariate nature of developmental plasticity, we evaluated how different combinations of environmental signals influence the development of morphological and behavioral traits. We raised Megaleporinus macrocephalus (Anostomidae) in four different developmental environments, and found that foraging position and structural complexity during development induced different morphotypes, which overlapped with behavioral patterns. Foraging position induced distinct patterns of mouth and fin positioning and overall body shape, which were accentuated by structural complexity. Moreover, fish most often chose conditions similar to their developmental environments. Combined signals during development, therefore, revealed environment‐specific phenotypic patterns associating morphology and behavior. Such results endorse the ability of developmental processes to influence the variation present in natural populations. Implications of addressing the multivariate essence of developmental plasticity transcend the evolutionary theory and inspire applications in several fields. Research Highlights: Integrated phenotypic responses arise from particular combinations of environmental signals.Plastic responses encompass concomitant and correlated changes.Environmental signals bias the development of morphological and behavioral traits in fish.

Both academics and practitioners consider a lack of knowledge about evolutionary theory to be a general barrier to effectively managing genetic diversity. However, it is challenging to judge practitioners' level of understanding and how this influences their management decisions. Knowledge built through experience may be difficult for practitioners to articulate, but could nonetheless result in appropriate management strategies. To date, researchers have assessed only the explicit (formal) knowledge practitioners have of evolutionary concepts. To explore practitioners' understanding of evolutionary concepts, it is necessary to consider how they might apply explicit and implicit knowledge to their management decisions. Using an online survey, we asked Australian practitioners to respond to 2 common management scenarios in which there is strong evidence that managing genetic diversity can improve outcomes: managing small, isolated populations and sourcing seeds for restoration projects. In describing their approach to these scenarios, practitioners demonstrated a stronger understanding of the effective management of genetic diversity than the definitions of the relevant concepts. However, their management of genetic diversity within small populations was closer to best practice than for restoration projects. Moreover, the risks practitioners described in implementing best practice management were more likely to affect their approach to restoration than translocation projects. These findings provide evidence that strategies to build the capacity of practitioners to manage genetic diversity should focus on realistic management scenarios. Given that practitioners recognize the importance of adapting their practices and the strong evidence for the benefits of actively managing genetic diversity, there is hope that better engagement by evolutionary biologists with practitioners could facilitate significant shifts toward evolutionarily enlightened management. Article impact statement: Better engagement with practitioners could facilitate significant shifts toward evolutionarily enlightened management. [ABSTRACT FROM AUTHOR]

This paper explores the use of Darwinian social evolutionary theory towards understanding the formation of nations through a specific engagement with John Hutchinson's Nations as Zones of Conflict, particularly the idea of 'culture wars'. After outlining Hutchinson's framework and the principles of Darwinian social evolutionary theory – namely, the key concepts of inheritance, variation, and selection within an environmental context – I make a case for Darwinian concepts being able to support and expand on Hutchinson's ethno‐symbolic approach. I argue that Darwinian social evolutionary theory offers a powerful explanation for why particular myths, symbols, traditions, and memories endure and are revived and revitalized in nationalist contexts. The development of nationalism in Meiji Japan is used as an example to explore these ideas. [ABSTRACT FROM AUTHOR]

Immunosenescence, the decline in immune defense with age, is an important mortality source in elderly humans but little is known of immunosenescence in wild animals. We systematically reviewed and meta‐analysed evidence for age‐related changes in immunity in captive and free‐living populations of wild species (321 effect sizes in 62 studies across 44 species of mammals, birds and reptiles). As in humans, senescence was more evident in adaptive (acquired) than innate immune functions. Declines were evident for cell function (antibody response), the relative abundance of naïve immune cells and an in vivo measure of overall immune responsiveness (local response to phytohaemagglutinin injection). Inflammatory markers increased with age, similar to chronic inflammation associated with human immunosenescence. Comparisons across taxa and captive vs free‐living animals were difficult due to lack of overlap in parameters and species measured. Most studies are cross‐sectional, which yields biased estimates of age‐effects when immune function co‐varies with survival. We therefore suggest longitudinal sampling approaches, and highlight techniques from human cohort studies that can be incorporated into ecological research. We also identify avenues to address predictions from evolutionary theory and the contribution of immunosenescence to age‐related increases in disease susceptibility and mortality.

(It is perhaps helpful that van den Brink is not only a theology professor, at the Vrije Universiteit Amsterdam, but also an ordained minister in the Protestant Church of the Netherlands.) Just as its title indicates, the purpose of Gijsbert van den Brink's I Reformed Theology and Evolutionary Theory i - a revised version of his I En de aarde bracht voort: Christelijk geloof en evolutie i (Uitgeverij Boekencentrum, 2017) - is to analyze the implications of evolutionary theory for Reformed theology. Chapter 7 focuses on the contention that such randomness is incompatible with divine providence; van den Brink dismisses the contention briskly and convincingly before broaching the idea that evolutionary convergence is not only compatible with but even "consonant with" divine providence.

Biological complexity is a key component of evolvability, yet its study has been hampered by a focus on evolutionary trends of complexification and inconsistent definitions. Here, we demonstrate the utility of bringing complexity into the framework of epigenetics to better investigate its utility as a concept in evolutionary biology. We first analyze the existing metrics of complexity and explore the link between complexity and adaptation. Although recently developed metrics allow for a unified framework, they omit developmental mechanisms. We argue that a better approach to the empirical study of complexity and its evolution includes developmental mechanisms. We then consider epigenetic mechanisms and their role in shaping developmental and evolutionary trajectories, as well as the development and organization of complexity. We argue that epigenetics itself could have emerged from complexity because of a need to self‐regulate. Finally, we explore hybridization complexes and hybrid organisms as potential models for studying the association between epigenetics and complexity. Our goal is not to explain trends in biological complexity but to help develop and elucidate novel questions in the investigation of biological complexity and its evolution. RESEARCH HIGHLIGHTS: This manuscript argues that biological complexity is better understood under the framework of epigenetics and that the epigenetic interactions emerge from the self‐regulation of complex systems. Hybrids are offered as models to study these properties. [ABSTRACT FROM AUTHOR]

How do we and should we decide what is morally right and what is morally wrong? For much of human history, the teachings of religion were presumed to provide either the answer, or much of the answer. Over time, two developments challenged this. The first was the establishment of the discipline of moral philosophy. Foundational texts, such as Immanuel Kant's Groundwork of the Metaphysics of Morals, and the growth of coherent, nonreligious approaches to ethics, notably utilitarianism, served to marginalize the role of religion. And then, second, the twentieth century saw the rapid growth of evolutionary biology with an enthusiastic presumption that biology was the source of ethics. Here, I begin by discussing these developments and then examine the extent to which religion is still needed for a coherent account of ethics. [ABSTRACT FROM AUTHOR]

The respondent agrees with Michael Reiss's general diagnosis of the rudderless state of ethics in our modern society, but not with all of his account of its causes or possible solutions. Scripture has always been limited in terms of direct moral commands, and secular ethics has, since Aristotle at least, been influential in directing Christian understanding of the "good life." Ethics must be based in biology, but evolutionary biology can tell us more readily what is, than guide us into "what ought" to be. Christian teaching classically emphasized moral formation, grounded in the understanding that we are creatures of a good Creator. We have our being as gift, and human life flourishes when oriented to the Good. [ABSTRACT FROM AUTHOR]

In this year's Boyle Lecture, Michael Reiss discusses the relationship between science, religion, and ethics. [Extracted from the article]

The aim of this paper is to explore in the light of recent scientific discoveries, coupled with a return to biblical orthodoxy, the question of the Fall (Augustine and Paul, Gen. 3, Rom. 7), and the apparent intergenerational conditions of original sin. This is the human condition – East of Eden. Invoking Darwin's theory of evolution through natural selection from random mutation as a means of repudiating the existence of original sin can no longer be sustained, scientifically; the biology of horizontal gene transfer (HGT), transgenerational epigenetics (TGE), accelerated evolution (AE) and biological plasticity (BP) has rendered Darwinism grounded in a Naturalistic methodology an inadequate explanation. If humanity is 'born this way' – mired in sin – have we condemned ourselves and our children to this status? How does this affect the relationship between biology and free will, between a form of predestination and decision‐making? Therefore, this paper is towards an understanding of the ontology of the original, or first, sin, and is a biblical and scientific exploration of postlapsarian humanity's self‐willed state, 'East of Eden.'

An implementation of punishment in the evolutionary theory of behavior dynamics is proposed, and is applied to responding on concurrent schedules of reinforcement with superimposed punishment. In this implementation, punishment causes behaviors to mutate, and to do so with a higher probability in a lean reinforcement context than in a rich one. Computational experiments were conducted in an attempt to replicate three findings from experiments with live organisms. These are (1) when punishment is superimposed on one component of a concurrent schedule, response rate decreases in the punished component and increases in the unpunished component, (2) when punishment is superimposed on both components at equal scheduled rates, preference increases over its no‐punishment baseline, and (3) when punishment is superimposed on both components at rates that are proportional to the scheduled rates of reinforcement, preference remains unchanged from the baseline preference. Artificial organisms animated by the theory, and working on concurrent schedules with superimposed punishment, reproduced all of these findings. Given this outcome, it may be possible to discover a steady‐state mathematical description of punished choice in live organisms by studying the punished choice behavior of artificial organisms animated by the evolutionary theory.

This article argues for the value of interdisciplinarity by attempting to integrate an evolutionary theory of human ontogeny with psychodynamic perspectives to explain the origins of an American cultural schema of marriage. Specifically, I draw on the work of evolutionary psychologist Michael Tomasello to propose that key features of the American "cultural" schema for marriage—commitment to it and the expectations it be shared, mutually beneficial, and lasting—are understandings that arise largely out of young human children's capabilities for emotional alignment or attunement and, thereafter, for fully developed joint intentionality. This focus of the American marital relationship on joint intentionality, and on even earlier beginnings of shared intentionality, I interpret as evidence—drawing on psychodynamic theory—that marriage as an American institution is largely a defense, a regression, that allows a return or "retreat" to feelings of dependency never fully resolved in adulthood because of the extreme emphasis on independence and self‐reliance in American child‐rearing.

Evolutionary biologists tend to approach the study of the natural world within a framework of adaptation, inspired perhaps by the power of natural selection to produce fitness advantages that drive population persistence and biological diversity. In contrast, evolution has rarely been studied through the lens of adaptation's complement, maladaptation. This contrast is surprising because maladaptation is a prevalent feature of evolution: population trait values are rarely distributed optimally; local populations often have lower fitness than imported ones; populations decline; and local and global extinctions are common. Yet we lack a general framework for understanding maladaptation; for instance in terms of distribution, severity, and dynamics. Similar uncertainties apply to the causes of maladaptation. We suggest that incorporating maladaptation‐based perspectives into evolutionary biology would facilitate better understanding of the natural world. Approaches within a maladaptation framework might be especially profitable in applied evolution contexts – where reductions in fitness are common. Toward advancing a more balanced study of evolution, here we present a conceptual framework describing causes of maladaptation. As the introductory article for a Special Feature on maladaptation, we also summarize the studies in this Issue, highlighting the causes of maladaptation in each study. We hope that our framework and the papers in this Special Issue will help catalyze the study of maladaptation in applied evolution, supporting greater understanding of evolutionary dynamics in our rapidly changing world.

In his commentary on the Journal of Traumatic Stress special issue on moral injury (Vol. 32, Issue 3), Nash (2019) critiques both Farnsworth's (2019) descriptive-prescriptive framework for differentiating posttraumatic stress disorder (PTSD) from moral injury and Farnsworth, Drescher, Evans, and Walser's (2017) functional contextual definition of moral injury and related concepts. To make his arguments, Nash contrasts these two frameworks with the Navy and Marine Corps Combat Operational Stress Control (COSC) model wherein moral stressors are presumed to cause literal damage to intrapsychic structures. Unfortunately, in drawing his comparisons, Nash makes several misstatements that we feel are important to clarify. We respond to Nash's commentary by first identifying the proper sources for the critiqued frameworks and correctly locate Farnsworth et al.'s functional contextual definition of moral injury within the domain of third-wave cognitive behavioral therapies. We go on to compare and contrast the respective origins of the COSC and functional contextual models, noting important differences in their intended purposes. Next, we defend our model against Nash's critiques by highlighting how a functional contextual approach to moral injury (a) links with evolutionary science, (b) captures multiple levels of analysis, (c) is parsimonious, (d) serves diverse populations, (e) directly informs interventions, (f) promotes moral humility, and (g) decreases stigma while preserving client autonomy. In our conclusion, we recognize the value of the COSC model for its intended purposes while also encouraging deep and respectful dialogue among researchers and clinicians regarding the proposed benefits of the functional contextual model of moral injury.

Since the 1970's, models based on evolutionary game theory, such as war of attrition (WOA), energetic war of attrition (E‐WOA), cumulative assessment model (CAM) and sequential assessment model (SAM), have been widely applied to understand how animals settle contests. Despite the important theoretical advances provided by these models, empirical evidence indicates that rules adopted by animals to settle contests vary among species. This stimulated recent discussions about the generality and applicability of models of contest. A meta‐analysis may be helpful to answer questions such as: (i) is there a common contest rule to settle contests; (ii) do contest characteristics, such as the occurrence of physical contact during the fight, influence the use of specific contest rules; and (iii) is there a phylogenetic signal behind contest rules? To answer these questions, we gathered information on the relationship between contest duration and traits linked to contestants' resource holding potential (RHP) for randomly paired rivals and RHP‐matched rivals. We also gathered behavioural data about contest escalation and RHP asymmetry. In contests between randomly paired rivals, we found a positive relationship between contest duration and loser RHP but did not find any pattern for winners. We also found a low phylogenetic signal and a similar response for species that fight with and without physical contact. In RHP‐matched rivals, we found a positive relationship between contest duration and the mean RHP of the pair. Finally, we found a negative relation between contest escalation and RHP asymmetry, even though it was more variable than the other results. Our results thus indicate that rivals settle contests following the rules predicted by WOA and E‐WOA in most species. However, we also found inconsistencies between the behaviours exhibited during contests and the assumptions of WOA models in most species. We discuss additional (and relatively untested) theoretical possibilities that may be explored to resolve the existing inconsistencies. [ABSTRACT FROM AUTHOR]

Rapid adaptation can aid invasive populations in their competitive success. Resource allocation trade‐off hypotheses predict higher resource availability or the lack of natural enemies in introduced ranges allow for increased growth and reproduction, thus contributing to invasive success. Evidence for such hypotheses is however equivocal and tests among multiple ranges over productivity gradients are required to provide a better understanding of the general applicability of these theories.Using common gardens, we investigated the adaptive divergence of various constitutive and inducible defence‐related traits between the native North American and introduced European and Australian ranges, while controlling for divergence due to latitudinal trait clines, individual resource budgets, and population differentiation, using >11,000 SNPs.Rapid, repeated clinal adaptation in defence‐related traits was apparent despite distinct demographic histories. We also identified divergence among ranges in some defence‐related traits, although differences in energy budgets among ranges may explain some, but not all, defence‐related trait divergence. We do not identify a general reduction in defence in concert with an increase in growth among the multiple introduced ranges as predicted trade‐off hypotheses.Synthesis: The rapid spread of invasive species is affected by a multitude of factors, likely including adaptation to climate and escape from natural enemies. Unravelling the mechanisms underlying invasives' success enhances understanding of eco‐evolutionary theory and is essential to inform management strategies in the face of ongoing climate change.

Summary: We reviewed the literature to understand the effects of glyphosate resistance on plant fitness at the molecular, biochemical and physiological levels. A number of correlations between enzyme characteristics and glyphosate resistance imply the existence of a plant fitness cost associated with resistance‐conferring mutations in the glyphosate target enzyme, 5‐enolpyruvylshikimate‐3‐phosphate synthase (EPSPS). These biochemical changes result in a tradeoff between the glyphosate resistance of the EPSPS enzyme and its catalytic activity. Mutations that endow the highest resistance are more likely to decrease catalytic activity by reducing the affinity of EPSPS for its natural substrate, and/or slowing the velocity of the enzyme reaction, and are thus very likely to endow a substantial plant fitness cost. Prediction of fitness costs associated with EPSPS gene amplification and overexpression can be more problematic. The validity of cost prediction based on the theory of evolution of gene expression and resource allocation has been cast into doubt by contradictory experimental evidence. Further research providing insights into the role of the EPSPS cassette in weed adaptation, and estimations of the energy budget involved in EPSPS amplification and overexpression are required to understand and predict the biochemical and physiological bases of the fitness cost of glyphosate resistance.

The helmeted guinea fowl Numida meleagris belongs to the order Galliformes. Its natural range includes a large part of sub‐Saharan Africa, from Senegal to Eritrea and from Chad to South Africa. Archaeozoological and artistic evidence suggest domestication of this species may have occurred about 2,000 years BP in Mali and Sudan primarily as a food resource, although villagers also benefit from its capacity to give loud alarm calls in case of danger, of its ability to consume parasites such as ticks and to hunt snakes, thus suggesting its domestication may have resulted from a commensal association process. Today, it is still farmed in Africa, mainly as a traditional village poultry, and is also bred more intensively in other countries, mainly France and Italy. The lack of available molecular genetic markers has limited the genetic studies conducted to date on guinea fowl. We present here a first‐generation whole‐genome sequence draft assembly used as a reference for a study by a Pool‐seq approach of wild and domestic populations from Europe and Africa. We show that the domestic populations share a higher genetic similarity between each other than they do to wild populations living in the same geographical area. Several genomic regions showing selection signatures putatively related to domestication or importation to Europe were detected, containing candidate genes, most notably EDNRB2, possibly explaining losses in plumage coloration phenotypes in domesticated populations.

We describe mechanisms of genetic innovation mediated by viruses and related elements that, during evolution, caused major genetic changes beyond what was anticipated by Charles Darwin. Viruses and related elements introduced genetic information and have shaped the genomes and immune systems of all cellular life forms. None of these mechanisms contradict Darwin's theory of evolution but extend it by means of sequence information that has recently become available. Not only do small increments of genetic information contribute to evolution, but also do major events such as infection by viruses or bacteria, which can supply new genetic information to a host by horizontal gene transfer. Thereby, viruses and virus‐like elements act as major drivers of evolution. [ABSTRACT FROM AUTHOR]

Conventional 20th century evolution thinking was based on the idea of isolated genomes for each species. Any possibility of life‐history inputs to the germ line was strictly excluded by Weismann's doctrine, and genome change was attributed to random copying errors. Today, we know that many life‐history events lead to rapid and nonrandom evolutionary change mediated by specific cellular functions. There are many ways that genomes, viruses, cells, and organisms interact to generate evolutionary variation. These include cell mergers and activation of natural genetic engineering by stress, infection, and interspecific hybridization. In addition, we know molecular mechanisms for transmitting life‐history information across generations through gametes. These discoveries require a new agenda for evolutionary theory and novel experimental designs to investigate the genomic impacts of stresses, biotic interactions, and sensory inputs coming from the environment. The review will offer some generic recommendations for enriching evolution experiments to incorporate new knowledge and find answers to previously excluded questions. [ABSTRACT FROM AUTHOR]

Islands are geographically defined as land masses completely surrounded by water, and island systems have been used as models for many biogeographic, ecological, and evolutionary theories ever since Darwin's pioneering efforts. However, their biological definition is complex. Over the past few decades these theories have been applied to many study systems that only share some geographic features with island systems. These features include spatial fragmentation, limited area, spatial and temporal isolation from adjacent parts of the system, and low connectivity between different parts within the system, to mention just a few. These systems vary in their form, the matrix that surrounds them, the factors defining their borders, the extent of insularity they impose on the different taxa, and their geological similarity to different types of actual islands. Here, I seek to understand whether such island‐like systems (ILS) function biologically as true islands. In the first part, I describe the wide diversity of ILS suggested in the literature and the variation in the features that define their insularity. In the second part, I review the extent to which the main theories of island biology are applicable to these systems: species–area and species–isolation relationships, community composition, evolutionary radiations, and the extent of endemism and genetic diversity. In the third and final part, I suggest a new conceptual framework within which to classify and study the biology of ILS, as well as practical future research directions. I conclude that the term 'biological island' is a multi‐faceted concept, loosely related to its geographical definition. As ILS are often less isolated than true islands, and their biological patterns are only partly similar to those of true islands (and even this is true only for some ILS) the use of the term 'island' to describe any isolated habitat is therefore inappropriate.

Landscape evolution models (LEMs) are dependent on their initial conditions (ICs). Commonly, LEMs use a horizontal surface with randomized perturbations as their IC and tend toward a steady state under constant forcing. The initial and steady state topographies are inherently linked, but they bear no obvious resemblance to each other. Here we reveal a connection by adding a shallow sinusoidal channel to the IC. This channel transforms into a deep canyon at steady state. Hence, the general behavior of LEMs is to indefinitely preserve topographic features from their ICs. Then we test whether experimental landscapes exhibit a similar behavior. In our experiments, we use the same sinusoidal signal, but find that it is ultimately erased. We believe that the culprit reorganizing processes are lateral channel migration and spatiotemporal variability in incision. Our results imply that LEMs are missing fundamental mechanisms and that long‐term preservation of ICs in erosional environments is unlikely. Plain Language Summary: Researchers use computer simulations and sandbox experiments to model how mountains develop over geologic time. The computer models are aptly named landscape evolution models. These models predict that rivers and mountains remain static on the landscape over long periods of time, but the experiments imply that they fluctuate endlessly. In this paper, we compare the landscape evolution models to landscape experiments and hypothesize that the reason they differ in their behavior is because the models are missing key processes that describe how rivers erode. Key Points: Numerical landscape evolution models preserve topographic signals from initial conditions indefinitelyExperimental landscapes frequently reorganize their drainage networks and destroy past topographic signalsIn the experiments, we suggest that lateral channel migration and autogenic knickpoints are the drivers of drainage network reorganization [ABSTRACT FROM AUTHOR]

The aim of this collection is to record a snapshot of our current state of understanding of the impact of fluids on the evolution and monitorability of subsurface rock formations during anthropogenic fluid injection/withdrawal operations, accounting for scale and frequency effects. In this introduction we provide a summary of the key challenges and findings reported in these 23 articles. This suite of articles addresses a variety of issues related to the impact of fluids on subsurface rocks, which can be grouped in three themes: (i) impact of fluids on wave velocity and attenuation/dispersion (five articles); (ii) fluids, fractures, and seismicity (nine articles); and (iii) dynamic fluid injection and substitution (nine articles).

The Campi Flegrei caldera is a large volcanic complex lying in the Campanian Plain, Southern Italy. During its history the caldera experienced episodes of bradyseism and intense swarm seismicity. The mechanism leading to unrest episodes is still debated, and great efforts are ongoing to improve the knowledge of this structure and its evolution due to the high volcanic risk in such a densely populated area. Here we present a resistivity model from a two‐dimensional inversion of audiomagnetotelluric data acquired along an approximately 5.6‐km long profile crosscutting the Solfatara‐Pisciarelli district and the Agnano plain. The resistivity model shows (1) very low resistivity values confined in the first 500 m of depth both in correspondence of the Solfatara‐Pisciarelli districts and the Agnano depression; (2) a resistive plume that extends underneath the Solfatara crater down to 2,000‐ to 3,000‐m depth, and (3) an adjoining relative conductive unit eastward. We discuss the resistivity structures in a multidisciplinary framework integrating inedited geochemical and seismological observations with existing surface geology and subsurface information. The Solfatara‐Pisciarelli district and the Agnano plain, both being expression of intense hydrothermal activity, show different characteristics. Below the Solfatara‐Pisciarelli area, the shallow conductive zone is interpreted as a faulted clay cap that overlies a highly active vapor‐dominated reservoir characterized by a convective mechanism. Conversely, below the Agnano plain, a liquid phase seems to prevail in the reservoir. The spatiotemporal variations of seismicity imply a combined action of preexisting tectonic lineaments and fluid interaction between the gas/steam reservoir and the outflow zone. Key Points: We present new audiomagnetotelluric, geochemical, and seismological observations data collected in the central‐eastern sector of Campi Flegrei calderaThe multidisciplinary analysis provides information on the structure and properties of the hydrothermal reservoir and of the fluid pathwaysSeismic events seem linked to the combined action of tectonic lineaments and fluid interactions between gas/steam reservoir and the outflow zone [ABSTRACT FROM AUTHOR]

In 2017, we demonstrated that transitions to cooperative breeding in Lamprologine cichlid fishes were not related to a species' social mating system (Dey et al. 2017. Nature Ecology & Evolution, 1, 137). This contrasted previous evidence that monogamy (and a low degree of promiscuity) promoted transitions to cooperative breeding in other taxa. Recently, Tanaka et al. (2018. Ethology, 124, 777–789) critiqued our study and argued that a re‐analysis of the data shows transitions to cooperative breeding are promoted by non‐monogamous mating systems. Here, we show that Tanaka et al.'s critique contains numerous inaccuracies. In addition, we show that the results put forth by Tanaka et al. emerge only under the extreme scenario in which all cooperative breeding species are classified as non‐monogamous, which we argue arises because Tanaka et al. confound social systems and mating systems. While we agree that there is uncertainty regarding the mating system of some Lamprologine species, we argue this uncertainty was sufficiently addressed through the extensive sensitivity analyses conducted in our original study.
