Der Zeitbegriff in der Geologie und das Evolutionsverständnis in der Biologie
Zur Dreigliederung der Käfer
On the threefoldness of beetles
Beetles are regarded in their systematic relationships as a superorganism. Concerning their evolutionary differentiation, is there any relation between the different organ-systems most animals have and the different beetle families, genera or species? Proceeding from a threefold analysis of highly… Read More
Heileurythmiewirkung auf das rhythmische System
The effect of curative eurythmy on the rhythmical system
In anthroposophical medicine, eurythmy is used therapeutically in
many cases and with different forms of disease. We report on two studies in which the effects of this therapeutic approach were studied with respect to the rhythmical-functional order of cardiac and… Read More
Signaturen der Therapeutischen Sprachgestaltung in der Herzfrequenzvariabilität
Signatures of therapeutic speech formation in heart rate variability
Background: Anthroposophical Therapeutie Speech uses poems and exercises which typically induce rhythmical breathing. Speaking influences respiration, and thus directly, heart rate variability (I IRV) in particular via respiratory sinus arrhythmia which, together With… Read More
Geschichte und Problem des Höherentwicklungsbegriffs

Concerning the evolutionary development of the blossom and fruit of the Ranunculaeeae
The fruit formation of the Ranunculaceae - evolutionarily early representatives of the angiosperms - is taken as a motif in examining the evolutiona1y path of the formation of both the angiosperm blossoms, exposed as they are to their surroundings, and… Read More
Korrelation von Sprossgestalt und Blattgestalt annueller Dikotyledonen
Correlation of the shapes of the shoot and leaf of annual dicotyledons
That the shape of a plant changes qualitatively and quantitatively during growth was noted as early as Aristotle. He tried to understand this process with the help of four»causes«(aitia) and four»rnotions«(kinesis). He thought that the formative force proceeds from… Read More

This indicates a homology between shoot growth and leaf growth. ‚Interesting malformations are described which could help… Read More
