Different sources of data on the evolution of segmentation lead to very different conclusions. Molecular similarities in the developmental pathways generating a segmented body plan tend to suggest a segmented common ancestor for all bilaterally symmetrical animals. Data from paleontology and comparative morphology suggest that this is unlikely. A possible solution to this conundrum is that throughout evolution there was a parallel co‐option of gene regulatory networks that had conserved ancestral roles in determining body axes and in (...) elongating the anterior‐posterior axis. Inherent properties in some of these networks made them easily recruitable for generating repeated patterns and for determining segmental boundaries. Phyla where this process happened are among the most successful in the animal kingdom, as the modular nature of the segmental body organization allowed them to diverge and radiate into a bewildering array of variations on a common theme.

Katarzyna de Lazari-Radek and Peter Singer argue that evolutionary considerations can resolve Sidgwick’s dualism of practical reason because such considerations debunk moral views that give weight to self-interested or partial considerations but cannot threaten the principle of universal benevolence. I argue that even if we grant these claims, this appeal to evolution is ultimately self-defeating. De Lazari-Radek and Singer face a dilemma. Either their evolutionary argument against partial morality succeeds, but then we need to also give up our conviction (...) that suffering is bad; or there is a way to defend this conviction, but then their argument against partiality fails. Utilitarians, I suggest, should resist the temptation to appeal to evolutionary debunking arguments. (shrink)

Professor H. James Birx shows how the never-ending controversy of human evolution came to be. He details the events that caused thinkers like Charles Darwin to develop his theory of evolution, and what ideas caused some people to reconcile a somewhat mystical theology with a concrete model of the universe. He tells you how Darwin's work infuriated everybody from "God-fearing" Christians to the church heirarchies. Birx explains how scientific advances and philosophical arguments have made beliefs about divine intervention (...) as the origin of man a moot point. He shows how creationism ignores proven scientific facts, and how human evolution remains a much sounder truth. You'll read how some western religions are starting to accept evolution as the process which creates life on earth. You'll also learn why scientific evolution and creationism have not been accepted together and how bold attempts to merge the two ideas have failed miserably. (shrink)

Evolution and Religion in American Education shines a light into one of America’s dark educational corners, exposing the regressive pedagogy that can invade science classrooms when school boards and state overseers take their eyes off the ball. It sets out to examine the development of college students’ attitudes towards biological evolution through their lives. The fascinating insights provided by interviewing students about their world views adds up to a compelling case for additional scrutiny of the way young people’s (...) educational experiences unfold as they consider—and indeed in some cases reject—one of science’s strongest and most cogent theoretical constructs. Inevitably, open discussion and consideration of the theory of evolution can chip away at the mental framework constructed by Creationists, eroding the foundations of their faith. The conceptual battleground is so fraught with logical challenges to Creationist dogma that in a number of cases students’ exposure to such dangerous ideas is actively prevented. This book provides a detailed map of this astonishing struggle in today’s America—a struggle many had thought was done and dusted with the onset of the Enlightenment. (shrink)

Alan Barnard's Language in Prehistory attempts to find an accommodation between linguistic and evolutionary theory and apply insights from archeology and anthropology to the origins and purposes of language. Rudolph Botha's Language Evolution: The Windows Approach is a critique of employing evidence from other fields. Botha also critiques conclusions drawn from pidgins and creoles, homesign, motherese, grammaticalization, language acquisition, protolanguage, and comparative animal behavior. This review attempts in turn to bring into question the appropriateness of applying the framework of (...) generative linguistics, and its style of argumentation, to prehistory. (shrink)

Two papers on global morality and ethics—by David Loye and Solomon H. Katz—are hereby placed into an evolutionary context. Simply stated though no less true, ethical evolution will likely be the next great evolutionary leap forward into the future—if humankind is to have a future.

This interdisciplinary volume brings together expert researchers coming from primatology, anthropology, ethology, philosophy of cognitive sciences, neurophysiology, mathematics and psychology to discuss both the foundations of non-human primate and human social cognition as well as the means there currently exist to study the various facets of social cognition. The first part focusses on various aspects of social cognition across primates, from the relationship between food and social behaviour to the connection with empathy and communication, offering a multitude of innovative approaches (...) that range from field-studies to philosophy. The second part details the various epistemic and methodological means there exist to study social cognition, in particular how to ascertain the proximal and ultimate mechanisms of social cognition through experimental, modelling and field studies. In the final part, the mechanisms of cultural transmission in primate and human societies are investigated, and special attention is given to how the evolution of cognitive capacities underlie primates’ abilities to use and manufacture tools, and how this in turn influences their social ecology. A must-read for both, young scholars as well as established researchers! (shrink)

EMERGENT EVOLUTION- THE GIFFORD LECTURES DELIVERED IN THE UNIVERSITY OF ST.

This is the conundrum that gives rise to the issue of tax avoidance: Although governments always seem to lack sufficient funds to support the needs of society, tax codes are often written that offer “a way out” of paying taxes for some but not all constituents. The ways out are referred to as loopholes that allow taxpayers to avoid taxes. This paper first defines the basic terms of tax avoidance and tax evasion and then offers an ethical review of (...) the morality of aggressive tax avoidance. Aggressive tax avoidance is then addressed in relationship a corporate entity’s tone at the top. The conclusion is drawn that use of the letter of the law to avoid payment of taxes sorely needed by governments for the good faith provision of public goods and services is ethically unacceptable. Several suggestions for change are provided, including a new financial statement disclosure and the possibility of a published corporate ethics report. (shrink)

The rapid growth in consumption of bottled water across the globe has drawn attention of policy makers and academicians alike. However, its consumption practices have been examined primarily in the context of industrialized countries. Drawing on studies of Science, Technology and Society, Public Understanding of Science, and institutions, this article explores the nuances of the consumption conundrum of bottled water in India. This mixed method study relies on data collected through surveys and ethnography of consumption practices at selected sites (...) in Delhi. We find reasons for bottled water consumption to vary with the site of consumption. Although the notions of “purity” and “scarcity” drive consumption behavior, these attributes are far from being objective. Rather, they are shaped by a complex mix of sociocultural factors, public understanding of science, and trust on various institutional mechanisms of water provisioning. (shrink)

Current books on evolutionary theory all seem to take for granted the fact that students find evolution easy to understand when actually, from a psychological perspective, it is a rather counterintuitive idea. Evolutionary theory, like all scientific theories, is a means to understanding the natural world. Understanding Evolution is intended for undergraduate students in the life sciences, biology teachers or anyone wanting a basic introduction to evolutionary theory. Covering core concepts and the structure of evolutionary explanations, it clarifies (...) both what evolution is about and why so many people find it difficult to grasp. The book provides an introduction to the major concepts and conceptual obstacles to understanding evolution, including the development of Darwin's theory, and a detailed presentation of the most important evolutionary concepts. Bridging the gap between the concepts and conceptual obstacles, Understanding Evolution presents evolutionary theory with a clarity and vision students will quickly appreciate. (shrink)

Philosophical naturalists claim macroevolution shows order emerging by pure chance. This claim is incompatible with accepted physical and biological principles. The present state of the universe is implicit in its initial state and the laws ofnature. Logical principles essential to science require these laws to be maintained by a self-conserving reality identifiable as God. Further, the laws share a common dynamic with human committed intentions. Both are logical propagators seen to the intentional by theists and naturalists alike. Mechanism and teleology (...) project a single reality into different conceptual spaces. Statistically, evolution is only possible given predefined goals. For fitness to be explanatory, it must be prior to survival events, entailing immanent goals verified by convergent evolution, toolkit genes, and evolutionary stasis. Aristotle's falsifiable claims for teleology are confirmed by evolution. Evolution is not random, but fully intentional, evidencing mind in nature. (shrink)

There is a broad public interest in the current discussion about evolution and creation, a discussion led mainly by scientists on the one hand and theologians on the other. The scientists argue for the evolution of the cosmos and nature without a creator, while the theologians defend the idea of creation. However, the perspective of natural philosophy is largely missing from the debate. Since this is no longer represented in contemporary philosophical trends, this study revives it from the (...) aristotelian-thomist tradition with its valuable insights into the finality of nature, which the author uses in his attempt to mediate between scientific and theological viewpoints.

This paper investigates how reticulate evolution contributes to a better understanding of human sociocultural evolution in general, and community formation in particular. Reticulate evolution is evolution as it occurs by means of symbiosis, symbiogenesis, lateral gene transfer, infective heredity, and hybridization. From these mechanisms and processes, we mainly zoom in on symbiosis and we investigate how it underlies the rise of (1) human, plant, animal, and machine interactions typical of agriculture, animal husbandry, farming, and industrialization; (2) (...) diet-microbiome relationships; and (3) host-virome and other pathogen interactions that underlie human health and disease. We demonstrate that reticulate evolution necessitates an understanding of behavioral and cultural evolution at a community level, where reticulate causal processes underlie the rise of synergistic organizational traits.

RésuméIl y a, dans la notion de dialectique moderne, deux perspectives de l'évolution intellectuelle: l'intelligence peut n'ětre encore que la pointe extrěme de l'adaptation biologique ou elle peut ětre déjà l'expression de la raison. C'est ce caractère ouvert des dialectiques scientifiques que nous retrouvons dans les interprétations étudiées ici: le pancalisme de Baldwin, la pensée sans images de Binet, l'interprétation de Janet et celle de Piaget, qui contribuent à enrichir la notion de genèse de l'intelligence et à en faire saisir (...) l'évolution.ZusammenfassungDie geistige Entwicklung wird in der modernen Dialektik aus zwei Gesichtspunkten erfasst, und zwar mag die Intelligenz wohl nur noch das äusserste Ende der biologischen Anpassung oder schon der Ausdruck der Vernunft sein. Das Offene eben der wissenschaftlichen Dialektiken finden wir in den hier erörterten Deutungen wieder, im Baldwinschen Pancalismus, im Denken ohne Bilder von Binet, in den Deutungen von Janet und von Piaget, die dazu beitragen, den Begriff von der Entstehungsgeschichte der Intelligenz zu bereichern und deren Evolution verständlich zu machen.There are two prospects of intellectual evolution in the notion of dialectics: intelligence can either be the ultimate point of biological adaptation or it can already be the expression of reason. Within this open characteristics of scientific dialectics are to be found the interpretations studied here: Baldwin's pancalism, Binet's » thought without image «, Janet's and Piaget's interpretations which help to enrich the knowledge of the genesis of intelligence and its evolution.

According to a profile in The Guardian , Mary Midgley is 'the foremost scourge of scientific pretensions in this country; someone whose wit is admired even by those who feel she sometimes oversteps the mark'. Considered one of Britain's finest philosophers, Midgley exposes the illogical logic of poor doctrines that shelter themselves behind the prestige of science. Always at home when taking on the high priests of evolutionary theory - Dawkins, Wilson and their acolytes - she has famously described (...) class='Hi'>evolution as 'the creation-myth of our age'. In Evolution as a Religion , she examines how science comes to be used as a substitute for religion and points out how badly that role distorts it. As ever, her argument is flawlessly insightful: a punchy, compelling, lively indictment of these misuses of science. Both the book and its author are true classics of our time. (shrink)

This monograph is a collection of conference contributions chosen by the editors who led a three-year project on evolution, cooperation, and rationality. The collected works are held together by a six-page introduction identifying common strands and differences of positions in the different chapters. Since no two chapters have a common author, the chapters do not build on each other. Rather, they offer a variety of perspectives on a number of different aspects of rationality and evolution. The monograph thus (...) does not offer a unified account of evolution and rationality despite the possibly somewhat misleading title, nor is there a clearly identifiable overarching theme that runs through the entire book.

We are reliable about logic in the sense that we by-and-large believe logical truths and disbelieve logical falsehoods. Given that logic is an objective subject matter, it is difficult to provide a satisfying explanation of our reliability. This generates a significant epistemological challenge, analogous to the well-known Benacerraf-Field problem for mathematical Platonism. One initially plausible way to answer the challenge is to appeal to evolution by natural selection. The central idea is that being able to correctly deductively reason conferred (...) a heritable survival advantage upon our ancestors. However, there are several arguments that purport to show that evolutionary accounts cannot even in principle explain how it is that we are reliable about logic. In this paper, I address these arguments. I show that there is no general reason to think that evolutionary accounts are incapable of explaining our reliability about logic. (shrink)

Recent studies on neural pathways in a broad spectrum of vertebrates suggest that, in addition to migration and an increase in the number of certain select neurons, a significant aspect of neural evolution is a “parcellation” (segregation-isolation) process that involves the loss of selected connections by the new aggregates. A similar process occurs during ontogenetic development. These findings suggest that in many neuronal systems axons do not invade unknown territories during evolutionary or ontogenetic development but follow in their ancestors' (...) paths to their ancestral targets; if the connection is later lost, it reflects the specialization of the circuitry.The pattern of interspecific variability suggests (1) that overlap of circuits is a more common feature in primitive (generalized) than in specialized brain organizations and (2) that most projections, such as the retinal, thalamotelencephalic, corticotectal, and tectal efferent ones, were bilateral in the primitive condition. Specialization of these systems in some vertebrate groups has involved the selective loss of connections, resulting in greater isolation of functions. The parcellation process may also play an important role in cell diversification.The parcellation process as described here is thought to be one of several underlying mechanisms of evolutionary and ontogenetic differentiation.

The study of cultural evolution has taken on an increasingly interdisciplinary and diverse approach in explicating phenomena of cultural transmission and adoptions. Inspired by this computational movement, this study uses Bayesian networks analysis, combining both the frequentist and the Hamiltonian Markov chain Monte Carlo (MCMC) approach, to investigate the highly representative elements in the cultural evolution of a Vietnamese city’s architecture in the early 20th century. With a focus on the façade design of 68 old houses in Hanoi’s (...) Old Quarter (based on 78 data lines extracted from 248 photos), the study argues that it is plausible to look at the aesthetics, architecture, and designs of the house façade to find traces of cultural evolution in Vietnam, which went through more than six decades of French colonization and centuries of sociocultural influence from China. The in-depth technical analysis, though refuting the presumed model on the probabilistic dependency among the variables, yields several results, the most notable of which is the strong influence of Buddhism over the decorations of the house façade. Particularly, in the top 5 networks with the best Bayesian Information Criterion (BIC) scores and p<0.05, the variable for decorations (DC) always has a direct probabilistic dependency on the variable B for Buddhism. The paper then checks the robustness of these models using Hamiltonian MCMC method and find the posterior distributions of the models’ coefficients all satisfy the technical requirement. Finally, this study suggests integrating Bayesian statistics in the social sciences in general and for the study of cultural evolution and architectural transformation in particular. (shrink)

There has been a long history of discussion whether intellectual or socioeconomic factors caused the rise of constitutional state and democracy, replacing the previous authoritarian forms of government. Some authors emphasized the role developmental psychology could play in illuminating the intellectual causes to these political phenomena. According to Piagetian researches, modern humankind has run through a psychogenetic evolution during the past several centuries. This psychological transformation entails higher forms of socio-moral consciousness decisive to the loss of legitimacy of authoritarian (...) forms and to the erection of more humane political forms such as constitutional state and democracy.

This paper considers Mary Midgley's views on evolution, especially as developed in her book Evolution as a Religion. In this she continues the critical campaign she waged against Dawkins’ notion of the selfish gene, but broadens her attack out to encompass many other thinkers, who are predicting dramatic and revolutionary futures for humanity, based supposedly on what evolutionary science tells us. Midgley argues that no such conclusions are scientifically warranted – hence evolution as a religion. Her own (...) attempts to absolve Darwin himself from this sort of scientism, and to remove from him any taint of social Darwinism are criticised, particularly by reference to The Descent of Man. Something is then said about Midgley's own alternative view of nature and humanity, a more holistic view, which itself has religious overtones. (shrink)

It is a matter of dispute how far back evolutionary explanations of social order should be traced. Evolutionary ideas certainly appear in the work of the ancient Greek philosophers, but it seems reasonable to identify the origins of modern evolutionary thinking in the eighteenth-century natural histories of civil society such as Rousseau’s Discourse on the Origin and Foundations of Inequality Among Men (1750: Pt III), Adam Ferguson’s An Essay on the History of Civil Society (1767), and Adam Smith’s Wealth of (...) Nations (1776: Bk III). In these eighteenth-century works, the explanation of current social institutions as an unplanned and generally adaptive development out of earlier and simpler arrangements gained traction. Germany too had a tradition of Naturphilosophie employing general evolutionary ideas, as well as Hegelian-influenced thinking on the development of societies. In 1863, four years after Darwin’s On the Origin of Species, August Schleicher’s Die Darwinsche Theorie und die Sprachwissenschaf, drew on these traditions as well as Darwin’s book to present an evolutionary account of the development of families of languages (Taub 1993), an endeavor that was carried on by a number of scholars in the later part of the nineteenth century.

Infants' own activities create and actively select their learning experiences. Here we review recent models of embodied information seeking and curiosity-driven learning and show that these mechanisms have deep implications for development and evolution. We discuss how these mechanisms yield self-organized epigenesis with emergent ordered behavioral and cognitive developmental stages. We describe a robotic experiment that explored the hypothesis that progress in learning, in and for itself, generates intrinsic rewards: The robot learners probabilistically selected experiences according to their potential (...) for reducing uncertainty. In these experiments, curiosity-driven learning led the robot learner to successively discover object affordances and vocal interaction with its peers. We explain how a learning curriculum adapted to the current constraints of the learning system automatically formed, constraining learning and shaping the developmental trajectory. The observed trajectories in the robot experiment share many properties with those in infant development, including a mixture of regularities and diversities in the developmental patterns. Finally, we argue that such emergent developmental structures can guide and constrain evolution, in particular with regard to the origins of language. (shrink)

Les questions que le philosophe peut aujourd'hui se poser sur l'évolution sont de deux ordres. Les unes relèvent de la philosophic des sciences (de quel genre de science s'agit-il ?). Les autres regardent la philosophic en général: dans quelle mesure l'évolution conduit-elle à réexaminer certaines grandes questions philosophiques traditionnelles, comme celles des fondements de l'épistémologie (théorie de la connaissance) et de l'éthique ? The questions a philosopher may raise today about evolution are twofold : on the one hand they (...) may refer to the philosophy of science (what kind of a science is it ?). On the other hand, they may refer to philosophy as such : in what way does evolution lead one to reexamine a few traditional philosophical question as that of the foundations of epistemology (a theory of knowledge) and ethics ?

Behavioral genetics and cultural evolution have both revolutionized our understanding of human behavior – largely independent of each other. Here, we reconcile these two fields under a dual inheritance framework, offering a more nuanced understanding of the interaction between genes and culture. Going beyond typical analyses of gene–environment interactions, we describe the cultural dynamics that shape these interactions by shaping the environment and population structure. A cultural evolutionary approach can explain, for example, how factors such as rates of innovation (...) and diffusion, density of cultural subgroups, and tolerance for behavioral diversity impact heritability estimates, thus yielding predictions for different social contexts. Moreover, when cumulative culture functionally overlaps with genes, genetic effects become masked, unmasked, or even reversed, and the causal effects of an identified gene become confounded with features of the cultural environment. The manner of confounding is specific to a particular society at a particular time, but a WEIRD (western, educated, industrialized, rich, and democratic) sampling problem obscures this boundedness. Cultural evolutionary dynamics are typically missing from models of gene-to-phenotype causality, hindering generalizability of genetic effects across societies and across time. We lay out a reconciled framework and use it to predict the ways in which heritability should differ between societies, between socioeconomic levels, and other groupings within some societies but not others, and over the life course. An integrated cultural evolutionary behavioral genetic approach cuts through the nature–nurture debate and helps resolve controversies in topics such as IQ. (shrink)

Key to Steve Fuller’s recent defense of intelligent design is the claim that it alone can explain why science is even possible. By contrast, Fuller argues that Darwinian evolutionary theory posits a purposeless universe leaving humans with no motivation to study science and no basis for modifying an underlying reality. I argue that this view represents a retreat from insights about knowledge within Fuller’s own program of social epistemology. I argue for a Darwinian picture of science as a product of (...) cultural evolution building upon biological capabilities and liabilities bequeathed to us by biological evolution. Dual Inheritance or Gene-Culture Coevolution Theory can help us understand how complex social institutions emerged out of distinct, if connected, processes of biological and cultural evolution. Only by understanding how the unnatural nature of modern science emerged through cultural evolution can we consider where modern science functions well or poorly. (shrink)

Examining homology in biological and cultural evolution is of great importance in investigations of humanity. The proposal presented in the target article retains substantial methodological weaknesses in the identification and use of “cultural traits.” However, with refined toolkits and the incorporation of recent advances in evolutionary theory, this overall endeavor can result in substantial payoffs for biological and social scientists.
