From the Victorian era to our own, critics of Herbert Spencer have portrayed his science‐based philosophical system as irrelevant to the concerns of practicing scientists. Yet, as a number of scholars have recently argued, an extraordinary range of reformist and experimental projects across the human and life sciences took their bearings from Spencer's work. This essay examines Spencerian science as practiced by the biologist, sociologist, and town planner Patrick Geddes (1854–1932). Through a close examination of his experimental natural history of (...) the late 1870s and early 1880s, his wider writings on the evolutionary process in the 1880s, and his efforts later in that decade to improve the slums of Edinburgh, this essay reveals Geddes's deep, unifying, and energizing commitment to Spencer's program. Recapturing that commitment can not only help historians rethink Spencerian science as practice but also suggest ways of overcoming the dichotomy between elite ideas and practical activity that bedevils much contemporary historiography of science.

Raphael Meldola (1849-1915), an industrial chemist and keen naturalist, under the influence of Darwin, brought new German studies on evolution by natural selection that appeared in the 1870s to the attention of the British scientific community. Meldola's special interest was in mimicry among butterflies; through this he became a prominent neo-Darwinian. His wide-ranging achievements in science led to appointments as president of important professional scientific societies, and of a local club of like-minded amateurs, particularly field naturalists. This is an account (...) of Meldola's early scientific connections and studies related to entomology and natural selection, his contributions to the study of mimicry, and his promotion in the mid-1890s of a more theory driven approach among entomologists.

In June 1909, scientists and dignitaries from 167 different countries gathered in Cambridge to celebrate the hundredth anniversary of Charles Darwin’s birth and the fiftieth anniversary of the publication of Origin of Species. The event was one of the most magnificent commemorations in the annals of science. Delegates gathered within the cloisters of Cambridge University not only to honor the “hero” of evolution but also to reassess the underpinnings of Darwinism at a critical juncture. With the mechanism of natural selection (...) increasingly under attack, evolutionary theory was in disarray. Against this backdrop, biologists weighed the impact of several new developments—the rediscovery of Mendel’s laws of heredity, de Vriesian mutation theory, and the linkage of sex‐cell division to the mechanism of heredity. The 1909 Darwin celebration thus represents a significant watershed in the history of modern biology that allows historians to assess the status of evolution prior to the advent of the chromosome theory of genetics.

In Darwinian Heresies, which was originally published in 2004, prominent historians and philosophers of science trace the history of evolutionary thought, and challenge many of the assumptions that have built up over the years. Covering a wide range of issues starting in the eighteenth century, Darwinian Heresies brings us through the time of Charles Darwin and the Origin, and then through the twentieth century to the present. It is suggested that Darwin's true roots lie in Germany, not his native England, (...) that Russian evolutionism is more significant than many are prepared to allow, and that the true influence on twentieth-century evolution biology was not Charles Darwin at all, but his often-despised contemporary, Herbert Spencer. The collection was intended to interest, to excite, to infuriate, and to stimulate further work. (shrink)

Comparative illustrations of vertebrate embryos by the leading nineteenth‐century Darwinist Ernst Haeckel have been both highly contested and canonical. Though the target of repeated fraud charges since 1868, the pictures were widely reproduced in textbooks through the twentieth century. Concentrating on their first ten years, this essay uses the accusations to shed light on the novelty of Haeckel’s visual argumentation and to explore how images come to count as proper representations or illegitimate schematics as they cross between the esoteric and (...) exoteric circles of science. It exploits previously unused manuscripts to reconstruct the drawing, printing, and publishing of the illustrations that attracted the first and most influential attack, compares these procedures to standard practice, and highlights their originality. It then explains why, though Haeckel was soon accused, controversy ignited only seven years later, after he aligned a disciplinary struggle over embryology with a major confrontation between liberal nationalism and Catholicism—and why the contested pictures nevertheless survived.

Inheritance and variation were a major focus of Charles Darwin’s studies. Small inherited variations were at the core of his theory of organic evolution by means of natural selection. He put forward a developmental theory of heredity (pangenesis) based on the assumption of the existence of material hereditary particles. However, unlike his proposition of natural selection as a new mechanism for evolutionary change, Darwin’s highly speculative and contradictory hypotheses on heredity were unfruitful for further research. They attempted to explain many (...) complex biological phenomena at the same time, disregarded the then modern developments in cell theory, and were, moreover, faithful to the widespread conceptions of blending and so-called Lamarckian inheritance. In contrast, Mendel’s approaches, despite the fact that features of his ideas were later not found to be tenable, proved successful as the basis for the development of modern genetics. Mendel took the study of the transmission of traits and its causes (genetics) out of natural history; by reducing complexity to simple particulate models, he transformed it into a scientific field of research. His scientific approach and concept of discrete elements (which later gave rise to the notion of discrete genes) also contributed crucially to the explanation of the existence of stable variations as the basis for natural selection. © Springer Science+Business Media B.V. 2010.

Dissatisfied with the descriptive and speculative methods of evolutionary biology of his time, the physiologist Jacques Loeb , best known for his “engineering” approach to biology, reflected on the possibilities of artificially creating life in the laboratory. With the objective of experimentally tackling one of the crucial questions of organic evolution, i.e., the origin of life from inanimate matter, he rejected claims made by contemporary scientists of having produced artificial life through osmotic growth processes in inorganic salt solutions. According to (...) Loeb, the answer to the question of whether or not life could be created artificially had to come from macro-molecular chemistry, in particular from the research on the recently discovered DNA. He was convinced that a prerequisite for making living matter from inanimate substances was the chemical synthesis of nuclear material capable of self-replication. Moreover, Loeb, experimentally refuting some vitalistic explanations as well as colloidal chemists’ far-reaching claims that biologically relevant macromolecules follow colloidal rather than chemical laws, pioneered research on the physical and chemical explanations of biological phenomena.

The nature/nurture debate is not dead. Dichotomous views of development still underlie many fundamental debates in the biological and social sciences. Developmental systems theory offers a new conceptual framework with which to resolve such debates. DST views ontogeny as contingent cycles of interaction among a varied set of developmental resources, no one of which controls the process. These factors include DNA, cellular and organismic structure, and social and ecological interactions. DST has excited interest from a wide range of researchers, from (...) molecular biologists to anthropologists, because of its ability to integrate evolutionary theory and other disciplines without falling into traditional oppositions. The book provides historical background to DST, recent theoretical findings on the mechanisms of heredity, applications of the DST framework to behavioral development, implications of DST for the philosophy of biology, and critical reactions to DST.

In Darwinism's Struggle for Survival Jean Gayon offers a philosophical interpretation of the history of theoretical Darwinism. He begins by examining the different forms taken by the hypothesis of natural selection in the nineteenth century and the major difficulties which it encountered, particularly with regard to its compatibility with the theory of heredity. He then shows how these difficulties were overcome during the seventy years which followed the publication of Darwin's Origin of Species, and he concludes by analysing the major (...) features of the genetic theory of natural selection, as it developed from 1920 to 1960. This rich and wide-ranging study will appeal to philosophers and historians of science and to evolutionary biologists. (shrink)

In this book Ron Amundson examines two hundred years of scientific views on the evolution-development relationship from the perspective of evolutionary developmental biology. This perspective challenges several popular views about the history of evolutionary thought by claiming that many earlier authors had made history come out right for the Evolutionary Synthesis. The book starts with a revised history of nineteenth-century evolutionary thought. It then investigates how development became irrelevant with the Evolutionary Synthesis. It concludes with an examination of the contrasts (...) that persist between mainstream evolutionary theory and evo-devo. This book will appeal to students and professionals in the philosophy and history of science, and biology. (shrink)

The reaction to Darwin's Origin of Species varied in many countries according to the roles played by national scientific institutions and traditions and the attitudes of religious and political groups. The contributors to this volume, including M. J. S. Hodge, David Hull, and Roberto Moreno, gathered in 1972 at an international conference on the comparative reception of Darwinism. Their essays look at early pro- and anti-Darwinism arguments, and three additional comparative essays and appendices add a larger perspective. For this paperback (...) edition, Thomas F. Glick has added a new preface commenting on recent research. (shrink)

The first book in English to examine in detail the scientific work of 19th-century Russian evolutionists, and the first in any language to explore the relationship of their theories to their economic, political, and natural milieu.

Ideas about heredity and evolution are undergoing a revolutionary change. New findings in molecular biology challenge the gene-centered version of Darwinian theory according to which adaptation occurs only through natural selection of chance DNA variations. In Evolution in Four Dimensions, Eva Jablonka and Marion Lamb argue that there is more to heredity than genes. They trace four "dimensions" in evolution -- four inheritance systems that play a role in evolution: genetic, epigenetic, behavioral, and symbolic. These systems, they argue, can all (...) provide variations on which natural selection can act. Evolution in Four Dimensions offers a richer, more complex view of evolution than the gene-based, one-dimensional view held by many today. The new synthesis advanced by Jablonka and Lamb makes clear that induced and acquired changes also play a role in evolution.After discussing each of the four inheritance systems in detail, Jablonka and Lamb "put Humpty Dumpty together again" by showing how all of these systems interact. They consider how each may have originated and guided evolutionary history and they discuss the social and philosophical implications of the four-dimensional view of evolution. Each chapter ends with a dialogue in which the authors engage the contrarieties of the fictional "I.M.," or Ifcha Mistabra -- Aramaic for "the opposite conjecture" -- refining their arguments against I.M.'s vigorous counterarguments. The lucid and accessible text is accompanied by artist-physician Anna Zeligowski's lively drawings, which humorously and effectively illustrate the authors' points. (shrink)

The essays in this collection examine developments in three fundamental biological disciplines--embryology, evolutionary biology, and genetics--in conflict with each other for much of the twentieth century. They consider key methodological problems and the difficulty of overcoming them. Richard Burian interweaves historical appreciation of the settings within which scientists work, substantial knowledge of the biological problems at stake and the methodological and philosophical issues faced in integrating biological knowledge drawn from disparate sources.

The evolutionary embryologist Gavin Rylands de Beer can be viewed as one of the forerunners of modern evolutionary developmental biology in that he posed crucial questions and proposed relevant answers about the causal relationship between ontogeny and phylogeny. In his developmental approach to the phylogenetic phenomenon of homology, he emphasized that homology of morphological structures is to be identified neither with the sameness of the underlying developmental processes nor with the homology of the genes that are in involved in the (...) development of the structures. De Beer’s work on developmental evolution focused on the notion of heterochrony, arguing that paedomorphosis increases morphological evolvability and is thereby an important mode of evolution that accounts for the origin of many taxa, including higher taxa.

Evolutionary theory is undergoing an intense period of discussion and reevaluation. This, contrary to the misleading claims of creationists and other pseudoscientists, is no harbinger of a crisis but rather the opposite: the field is expanding dramatically in terms of both empirical discoveries and new ideas. In this essay I briefly trace the conceptual history of evolutionary theory from Darwinism to neo-Darwinism, and from the Modern Synthesis to what I refer to as the Extended Synthesis, a more inclusive conceptual framework (...) containing among others evo–devo, an expanded theory of heredity, elements of complexity theory, ideas about evolvability, and a reevaluation of levels of selection. I argue that evolutionary biology has never seen a paradigm shift, in the philosophical sense of the term, except when it moved from natural theology to empirical science in the middle of the 19th century. The Extended Synthesis, accordingly, is an expansion of the Modern Synthesis of the 1930s and 1940s, and one that—like its predecessor—will probably take decades to complete. (shrink)

Just before Ernst Haeckel’s death in 1919, historians began piling on the faggots for a splendid auto-da-fé. Though more people prior to the Great War learned of Darwin’s theory through his efforts than through any other source, including Darwin himself, Haeckel has been accused of not preaching orthodox Darwinian doctrine. In 1916, E. S. Russell, judged Haeckel's principal theoretical work, Generelle Morphologie der Organismen, as "representative not so much of Darwinian as of pre-Darwinian thought."1 Both Stephen Jay Gould and Peter (...) Bowler endorse this evaluation, and see as an index of Haeckel’s heterodox deviation his use of the biogenetic law that ontogeny recapitulates phylogeny.2 Michael Ruse, without much analysis, simply proclaims that “Haeckel and friends were not true Darwinians.”3 These historians locate the problem in Haeckel’s inclinations toward Naturphilosophie and in his adoption of the kind of Romantic attitudes characterizing the earlier biology of Goethe. These charges of heresy assume, of course, that Darwin’s own theory harbors no taint of Romanticism and that it consequently remains innocent of the doctrine of recapitulation. I think both assumptions quite. (shrink)
