The relatively late acceptance of Darwinism in German biology and paleontology is frequently attributed to a lingering of Lamarckism, a persisting influence of German idealistic Naturphilosophie and Goethean romanticism. These factors are largely held responsible for the vitalism underlying theories of saltational and orthogenetic evolutionary change that characterize the writings of many German paleontologists during the first half of the 20th century. A prominent exponent of that tradition was Karl Beurlen, who is credited with having been the first German (...) paleontologist to present a full-fledged theory of saltational evolution and orthogenetic change. A review of Beurlen's writings reveals motives and concerns far more complex, however, and firmly rooted in contemporary völkisch thought and Aryan Science. Beurlen's mature theory of evolution can indeed be understood as his own contribution to Aryan Geology and Biology, tainted as it was with National-Socialist ideology. Evolutionary biologists of the time who opposed the theories of Beurlen and likeminded authors, i.e., idealistic morphology, typology, saltational change, orthogenesis and cyclism did so on Darwinian principles, which ultimately prevailed. But at the time when the battle was fought, their adherence to the principle of natural selection was likewise ideologically tainted, namely in terms of racial theory. National-Socialist ideology was unable to forge a unity of evolutionary theory in Germany even amongst those of its proponents who endorsed this ideology. (shrink)

The darwinistic doctrine of a continuous transformation of the animal world cannot be certified by Paleontology. On the contrary the building-plans of the animals present themselves ready made in the history of the earth. That may be shown before all at the oldest vertebrates which appear in the Silur and Devon in types fundamentally differentiated. Also the higher fishes, the amphibia, reptiles, birds and mammals present themselves ready made and are not to be derived one from another. Beyond the reach (...) of families descendance is unknown; it can, if anyhow, be maintained in the sense of a modification within typologically determined boundaries.Beurlen's Neomorphosis must be refused. The will for might, i.e. the will for dominating the world around, does not exist as a formgiving element, and can, before all, not be responsible there where the new type is separated from the old one by not adaptive, and therefore building constructive qualities.Remonstrances showing that the tradition having gaps in paleontology should not admit the above made conclusions are refused. The things found are, on the contrary, fully sufficient, asHeribert-Nilsson also showed for the fossil floras. The typological manner of contemplating has deciding importance in paleontology, whereas that of the theory of descendance only has a secondary one.La doctrine darwinienne d'une transformation continue du monde animal ne peut pas être confirmée par la paléontologie. Les plans constructifs des animaux apparaissent plutôt achevés dans l'histoire de la terre. Cela se montre avant tout aux plus anciens vertébrés qui font leur apparition dans le silure et le devon par des types variés et différenciés fondamentalement. Aussi les poissons de genres plus élevés, les amphibiens, les reptiles, les oiseaux et les mammifères se présentent achevés et ne sont pas dérivés les uns des autres. En dehors du domaine de la famille la descendance est inconnue, et elle ne pourrait être maintenue que dans le sens de modification au dedans de limites prescrites typologiquement. Il faut rejeter la néomorphose deBeurlen. La volonté du pouvoir, c'est-à-dire la volonté de dominer le milieu n'existe pas comme un facteur créateur de formes et ne peut pas avant tout être responsable là où le nouveau type est séparé de l'ancien par des qualités non adaptives, donc des qualités constructives.Les objections qui veulent prouver qu'une tradition paléontologique, pleine de lacunes, n'admet pas les conclusions faites ci-dessus, sont complètement réfutées. Les découvertes suffisent plutôt complètement, commeHeribert-Nilsson l'a démontré, pour les flores fossiles. La manière typologique de contempler a une signification décisive dans la paléontologie, celle de la théorie de la descendance a seulement une signification secondaire. (shrink)
