Abstract Ronald Aylmer Fisher (1890–1962) is today remembered as a giant of twentieth-century statistics, genetics and evolutionary theory. Alongside his influential scientific contributions, he was also, throughout the interwar years, a prominent figure within Britain's eugenics movement. This essay provides a close examination of his eugenical ideas and activities, focusing particularly upon his energetic advocacy of family allowances, which he hoped would boost eugenic births within the more ‘desirable’ middle and upper classes. Fisher's proposals, which were grounded in his distinctive explanation for the decay of civilizations throughout human history, enjoyed support from some influential figures in Britain's Eugenics Society and beyond. The ultimate failure of his campaign, though, highlights tensions both between the eugenics and family allowances movements, and within the eugenics movement itself. I show how these social and political movements represented a crucial but heretofore overlooked context for the reception of Fisher's evolutionary masterwork of 1930, The Genetical Theory of Natural Selection, with its notorious closing chapters on the causes and cures of national and racial decline.

Twentieth-century psychology took a modernist form, giving Darwin’s approach to agency an unscientific look. Meanwhile, twentieth-century biologists were reconstructing evolutionary theory to highlight molecular genetics, reducing Darwin’s far-reaching writings about the living world to one grand idea: natural selection. Advances in biology today, which ground evolutionary thinking in a theory of the organism (or phenotype), find new wisdom in Darwin’s vision of the world. This vision has two axes. One describes the interwoven lives of the creatures who fill a given habitat, making interdependence central—a theatre of agency or ‘struggle for life.’ The other is what that struggle effects over time periods measured in millions of years, namely: evolution. Like his law of natural selection, Darwin’s psychology drew primarily on his understandings of the theatre of agency, whether discussing the actions of humans, animals, or plants—as the chapters of this book will show.

On at least four occasions, Edgar Anderson (1897–1969) began revising his book Plants, man and life (1952). Given both its place in Anderson's career and his place in the development of evolutionary theory in the mid-twentieth century, the emendations are noteworthy. Though a popular work, Plants, man and life served as the distillation of Anderson's ideas on hybridization as an evolutionary mechanism, the need for more scientific attention on domesticated and semi-domesticated plants, and the opportunities such plants provided for the study of evolution. Anderson was an active participant in several key events in what historians have come to call the Evolutionary Synthesis. For example, he and Ernst Mayr shared the 1941 Jesup Lectures on “Systematics and the origin of species”. Anderson's proposed revisions to his book reflect both an attempt to soften certain acerbic comments as well as an attempt to recast the book as a whole.

Descent Of Man

Charles Robert Darwin, the English naturalist, published On the Origin of Species in 1859 and the follow-up work The Descent of Man in 1871. In these works, he argued for his theory of evolution through natural selection, applying it to all organisms, living and dead, including our own species, Homo sapiens. Although controversial from the start, Darwin’s thinking was deeply embedded in the culture of his day, that of a middle-class Englishman. Evolution as such was an immediate success in scientific circles, but although the mechanism of selection had supporters in the scientific community (especially among those working with fast-breeding organisms), its real success was in the popular domain. Natural selection, and particularly the side mechanism of sexual selection, were known to all and popular themes in fiction and elsewhere.

Evolutionary Perspectives

Abstract In Geological Evidences of the Antiquity of Man (1863), Charles Lyell appraised the distinct contribution made by his protégé, Charles Darwin (On the Origin of Species (1859)), to evolutionary theory: ‘Progression … is not a necessary accompaniment of variation and natural selection [… Darwin’s theory accounts] equally well for what is called degradation, or a retrogressive movement towards a simple structure’. In Rhoda Broughton’s first novel, Not Wisely, but Too Well (1867), written contemporaneously with Lyell’s book, the Crystal Palace at Sydenham prompts precisely this sort of Darwinian ambivalence to progress; but whether British civilization ‘advance[s] or retreat[s]’, her narrator adds that this prophesized state ‘will not be in our days’ – its realization exceeds the single lifespan. This article argues that Not Wisely, but Too Well is attentive to the irreconcilability of Darwinism to the Victorian ‘idea of progress’: Broughton’s novel, distinctly from its peers, raises the retrogressive and nihilistic potentials of Darwin’s theory and purposes them to reflect on the status of the individual in mid-century Britain.

Evolutionary Explanations

Recent arguments concerning the nature of causation in evolutionary theory, now often known as the debate between the 'causalist' and 'statisticalist' positions, have involved answers to a variety of independent questions – definitions of key evolutionary concepts like natural selection, fitness, and genetic drift; causation in multi-level systems; or the nature of evolutionary explanations, among others. This Element offers a way to disentangle one set of these questions surrounding the causal structure of natural selection. Doing so allows us to clearly reconstruct the approach that some of these major competing interpretations of evolutionary theory have to this causal structure, highlighting particular features of philosophical interest within each. Further, those features concern problems not exclusive to the philosophy of biology. Connections between them and, in two case studies, contemporary metaphysics and philosophy of physics demonstrate the potential value of broader collaboration in the understanding of evolution.

Proximate Causation

Evolutionary theory has been extended almost continually since the evolutionary synthesis (ES), but except for the much greater importance afforded genetic drift, the principal tenets of the ES have been strongly supported. Adaptations are attributable to the sorting of genetic variation by natural selection, which remains the only known cause of increase in fitness. Mutations are not adaptively directed, but as principal authors of the ES recognized, the material (structural) bases of biochemistry and development affect the variety of phenotypic variations that arise by mutation and recombination. Against this historical background, I analyse major propositions in the movement for an ‘extended evolutionary synthesis’. ‘Niche construction' is a new label for a wide variety of well-known phenomena, many of which have been extensively studied, but (as with every topic in evolutionary biology) some aspects may have been understudied. There is no reason to consider it a neglected ‘process’ of evolution. The proposition that phenotypic plasticity may engender new adaptive phenotypes that are later genetically assimilated or accommodated is theoretically plausible; it may be most likely when the new phenotype is not truly novel, but is instead a slight extension of a reaction norm already shaped by natural selection in similar environments. However, evolution in new environments often compensates for maladaptive plastic phenotypic responses. The union of population genetic theory with mechanistic understanding of developmental processes enables more complete understanding by joining ultimate and proximate causation; but the latter does not replace or invalidate the former. Newly discovered molecular phenomena have been easily accommodated in the past by elaborating orthodox evolutionary theory, and it appears that the same holds today for phenomena such as epigenetic inheritance. In several of these areas, empirical evidence is needed to evaluate enthusiastic speculation. Evolutionary theory will continue to be extended, but there is no sign that it requires emendation.

AbstractThis article provides the first account of key texts and concepts in the theory and criticism of Arthur Trystan Edwards. Edwards's notion of ‘civic design’, which emanated from the Liverpool School of Architecture in the second decade of the twentieth century, was part of a broader international trend (particularly in the US and Europe) towards formal, axial and monumental planning. Edwards imbued civic design with a philosophical and political sophistication that set him apart from many of his non-Modernist contemporaries. The article discusses the underlying precepts — such as ‘subject’, ‘form’, ‘urbanity’ and ‘manners’ — in some of Edwards's critical texts, including Good and Bad Manners in Architecture (1924). The final section traces his pioneering interest in high-density, low-rise housing, which culminated with the establishment of the Hundred New Towns Association in 1933–34.

Neo-Darwinian evolutionary theory explains how the appearance of purposive design in the adaptations of living organisms can have come about without their intentionally being designed. The explanation relies crucially on the possibility of certain physical processes : mainly, gene replication and natural selection . In this paper, I show that for those processes to be possible without the design of biological adaptations being encoded in the laws of physics, those laws must have certain other properties. The theory of what these properties are is not part of evolution theory proper, yet without it the neo-Darwinian theory does not fully achieve its purpose of explaining the appearance of design. To this end, I apply constructor theory's new mode of explanation to express exactly within physics the appearance of design, no-design laws, and the logic of self-reproduction and natural selection. I conclude that self-reproduction, replication and natural selection are possible under no-design laws, the only non-trivial condition being that they allow digital information to be physically instantiated. This has an exact characterization in the constructor theory of information. I also show that under no-design laws an accurate replicator requires the existence of a ‘vehicle’ constituting, together with the replicator, a self-reproducer.

This book investigates a wide range of ideas, theories, and existing empirical research relevant to the study of the complex and diverse phenomenon of human cooperation. Issues relating to cooperation are examined from the perspective of evolutionary theory, political science, and related social sciences. The book draws upon two bodies of work: Mancur Olson's The Logic of Collective Action (1965) and George C. Williams's Adaptation and Natural Selection (1966). Olson, an economist, and Williams, an evolutionary biologist, both argued that a focus on groups would not provide a complete understanding of collective action and other social behaviors. This introductory chapter discusses some important definitions relating to cooperation, with particular emphasis on collective action and collective action dilemmas, along with coordination and coordination problems. It also provides an overview of the chapters that follow.
