Monism and Morphology at the Turn of the Twentieth Century
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by IUScholarWorks From a draft. May differ from the published version, which appeared in Monism: Science, Philosophy, Religion, and the History of a Worldview, ed. Todd Weir, 135–158, New York: Palgrave USA, 2012. Monism and Morphology at the Turn of the Twentieth Century SANDER GLIBOFF Indiana University Abstract. Ernst Haeckel’s monistic worldview and his interpretation of Darwin’s theory of evolution worked together to help him rule out any role for divine providence or any non-material mind, spirit, will, or purpose in the organic world. In his account of 1866, the impersonal, unpredictable, and purposeless external environment was what drove evolutionary change. By around the turn of the twentieth century, however, new theories of evolution, heredity, and embryology were challenging Haeckel’s, but Haeckel no longer responded with his earlier vigor. Younger monistically oriented evolutionary biologists had to take the lead in modernizing and defending the monistic interpretation and the external causes of evolution. Three of these younger biologists are discussed here: Haeckel’s student, the morphologist-turned-theoretician Richard Semon (1859–1918); Ludwig Plate (1862–1937), who took over Haeckel’s chair at the University of Jena and became an influential journal editor and commentator on new research on heredity and evolution; and Paul Kammerer (1880–1926), whose experimental evidence for the modifying power of the environment was hotly debated. Despite their very different social, political, and religious backgrounds, their contrasting research methods and career trajectories, and their disagreements on the precise mechanisms of evolution, these three were united by their adherence to Haeckelian monistic principles. -
Phylogeny and Evolution of Myrmecophily in Beetles, Based on Morphological Evidence (Coleoptera: Ptinidae, Scarabaeidae)
Phylogeny and Evolution Of Myrmecophily In Beetles, Based On Morphological Evidence (Coleoptera: Ptinidae, Scarabaeidae) DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Glené Mynhardt Graduate Program in Evolution, Ecology and Organismal Biology The Ohio State University 2012 Dissertation Committee: Johannes Klompen, Advisor Marymegan Daly Norman Johnson T. Keith Philips Copyright by Glené Mynhardt 2012 Abstract Ant-associated behavior has evolved rampantly among various groups of Arthropoda, and has arisen in at least 34 families of beetles. Due to the amazing morphological modifications and different kinds of interactions that occur within myrmecophilous (ant-associated) beetles, authors have predicted that myrmecophily has evolved in a step-wise fashion from casual, facultative associations to closely integrated, obligate interactions. In this dissertation, myrmecophily within the Coleoptera is reviewed, and known behaviors, ant-beetle interactions, and associated morphological adaptations are discussed. In order to better understand how myrmecophily has evolved, two groups of beetles are studied in a phylogenetic context. A cladistic analysis of 40 species of the myrmecophilous scarab genus, Cremastocheilu s Knoch is presented. Characters related to a myrmecophilous habit are largely informative, especially those characters related to the glandular trichomes (clusters of setae typically associated with exocrine glands). Two of the five previously recognized subgenera, C. (Myrmecotonus ) and C. (Anatrinodia ) are synonymized with the subgenus C. (Cremastocheilus ). Even though behavioral information is only known for a few species, the resulting phylogeny indicates that monophyletic subgenera are largely associated with the same ant hosts, although specific interactions with ant hosts can vary even in closely-related taxa. -
Ernst Haeckel and the Struggles Over Evolution and Religion
89 Ernst Haeckel and the Struggles over Evolution and Religion Robert J. Richards1 Abstract As a young man, Ernst Haeckel harbored a conventional set of Evangelical beliefs, mostly structured by the theology of Schleiermacher. But the conversion to Darwinian theory and the sudden death of his young wife shifted his ideas to the heterodox mode, more in line with Goethe and Spinoza. Haeckel’s battles with the religiously minded became more intense after 1880, with attack and counterattack. He particularly engaged Erich Wasmann, a Jesuit entomologist who had become an evolutionist, and the Keplerbund, an organization of Protestant thinkers who opposed evolutionary theory and accused him of deliberate fraud. In these struggles, Haeckel defined and deepened the opposition between traditional religion and evolutionary theory, and the fight continues today. If religion means a commitment to a set of theological propositions regarding the nature of God, the soul, and an afterlife, Ernst Haeckel (1834-1919) was never a religious en- thusiast. The influence of the great religious thinker Friedrich Daniel Schleiermacher (1768-1834) on his family kept religious observance decorous and commitment vague.2 The theologian had maintained that true religion lay deep in the heart, where the inner person experienced a feeling of absolute dependence. Dogmatic tenets, he argued, served merely as inadequate symbols of this fundamental experience. Religious feeling, accord- ing to Schleiermacher’s Über die Religion (On religion, 1799), might best be cultivated by seeking after truth, experiencing beauty, and contemplating nature.3 Haeckel practiced this kind of Schleiermachian religion all of his life. Haeckel’s association with the Evangelical Church, even as a youth, had been con- ventional. -

On the Parallel Emergence of Phenotypic Similarity Under Domestication
Sign Systems Studies 37(3/4), 2009 Monsters we met, monsters we made: On the parallel emergence of phenotypic similarity under domestication Karel Kleisner1, Marco Stella2 1 Department of Philosophy and History of Science, Charles University, Viničná 7, 128 44 Prague, Czech Republic e-mail: [email protected] 2 Department of Anthropology, Faculty of Humanities, Charles University, Husníkova 2075, 15000 Prague, Czech Republic e-mail: [email protected] Abstract. Creatures living under the rule of domestication form a communicative union based on shared morphological, behavioural, cognitive, and immunological resemblances. Domestic animals live under particular conditions that substantially differ from the original (natural) settings of their wild relatives. Here we focus on the fact that many parallel characters have appeared in various domestic forms that had been selected for different purposes. These characters are often unique for domestic animals and do not exist in wild forms. We argue that parallel similarities appear in different groups in response to their interaction with the umwelt of a particular host. In zoosemiotic sense, the process of domestication represents a kind of interaction in which both sides are affected and eventually transformed in such a way that one is more integrated with the other than in the time of initial encounter. 1.

Despite their very different social, political, and religious backgrounds, their contrasting research methods and career trajectories, and their disagreements on the precise mechanisms of evolution, these three were united by their adherence to Haeckelian monistic principles. Together they illustrate the continuing importance of Haeckel’s biological and ideological program in the twentieth century, its ability to adapt to new theoretical and methodological challenges, and its successful defense of the purposelessness of Darwinian variation and the non-directedness of evolution.
