The Dutch biologist C J. van der Klaauw (1893–1972) structuralized the epistemology of oecology using concepts which exceeded the limits of a strictly teleological interpretation of nature. This article relates to his theory of holistic oecology which van der Klaauw formulated departing from a critical confrontation with Kant's teleological view on nature. He substituted this extra-scientifically heuristic maxim by the holistic notion of network-like associations between organisms within a community. The analogous similarities between the organization of individual organisms and communities (...) drawn up by van der Klaauw, merely remained propaedeutics for a genuine holistic oecology, which would only employ epistemological principles specifically referring to the organization of supra-individual communities of organisms. This article discusses the process of structuralizing the theory of holistic oecology by van der Klaauw in his dialogue with Kantian philosophy. (shrink)

With Carl Gegenbaur and Ernst Haeckel, inspiredby Darwin and the cell theory, comparativeanatomy and embryology became established andflourished in Jena. This tradition wascontinued and developed further with new ideasand methods devised by some of Haeckelsstudents. This first period of innovative workin evolutionary morphology was followed byperiods of crisis and even a disintegration ofthe discipline in the early twentieth century.This stagnation was caused by a lack ofinterest among morphologists in Mendeliangenetics, and uncertainty about the mechanismsof evolution. Idealistic morphology was stillinfluental in (...) Germany, which prevented a fullappreciation of the importance of Darwinstheory of natural selection for comparativemorphology. Evolutionary morphology andembryology failed to contribute significantlyto the modern synthesis of evolutionarybiology, thereby probably delaying theintegration of developmental biology intomodern evolutionary biology. However, Haeckelsstudent Oscar Hertwig, as well as Victor Franzand Alexej N. Sewertzoff from a youngergeneration, all tried to forge their ownsynthetic approaches in which (inspired byHaeckels work) embryology played an importantrole. Important for all three researchers wereattempts to refine, and sometimes redefine, thebiogenetic law, and to find new scientificexplanations for it (and for the manyexceptions to it). Their research was latermore or less forgotten, and had littleinfluence on the architects of the modernsynthesis. As the relationship betweenevolutionary and developmental biology is nowagain rising in importance in the form ofEvo-Devo, we would like to draw attention tohow this earlier research tradition grappledwith similar questions to those now on theagenda, albeit from sometimes quite differentperspectives.

Morphological elements, or structures, are sorted into four categories depending on their level of anatomical isolation and the presence or absence of intrinsically identifying characteristics. These four categories are used to highlight the difficulties with the concept of structure and our ability to identify or define structures. The analysis is extended to the concept of homology through a discussion of the methodological and philosophical problems of the current concept of homology. It is argued that homology is fundamentally a similarity based (...) concept rather than a phylogenetic concept, and a proposal is put forth to return to a comparative context for homology. It is shown that for both the concepts of structure and homology ana priori assumption of stable underlying patterns (i.e. archetypes) is essential. (shrink)

On the basis of a comparative analysis of the biosemiotic work of Jakob von Uexküll and of various theories on biological holism, this article takes a look at the question: what is the status of a semiotic approach in respect to a holistic one? The period from 1920 to 1940 was the peak-time of holistic theories, despite the fact that agreement on a unified and accepted set of holistic ideas was never reached. A variety of holisms, dependent on the cultural (...) and disciplinary contexts, is sketched here from the works of Jan Smuts, Adolf Meyer-Abich, John Scott Haldane, Kurt Goldstein, Alfred North Whitehead and Wolfgang Köhler. In contrast with his contemporary holists, who used the model of an organism as a unifying explanatory tool for all levels of reality, Jakob von Uexküll confined himself to disciplinary organicism by extending the borders of the definition of “organism” without any intention to surpass the borders of biology itself. The comparison reveals also a significant difference in the perspectives of Uexküll and his contemporary holists, a difference between a view from a subjective centre in contrast with an all-encompassing structural view. Uexküll’s theories are fairly near to J. S. Haldane’s interpretation of an organism as a coordinative centre, but even here their models do not coincide. Although biosemiotics and holistic biology have different theoretical starting points and research-goals, it is possible nonetheless to place them under one and the same doctrinal roof. (shrink)
