The effect of human recombinant erythropoietin (rEPO) on the reticulocyte count and the reticulocyte maturation distribution in rats was measured with an automatic reticulocyte analysis system (AURAS). The strongest reaction was found on the third day after a single application of rEPO with respect to reticulocyte count, maturation distribution, and the(More)
For several decades experimental biology and medicine have both been accompanied by a dichotomy between reductionistic and anti-reductionistic approaches. In the present paper it is proposed that this dichotomy can be overcome if it is accepted that research on different organizational levels of the organism is necessary. The relevance of such an approach(More)
The hypothesis is advanced that major evolutionary innovations are characterized by an increase of organismal autonomy in the sense of an emancipation from the environment. After a brief overview of the literature on this concept, increasing autonomy is defined as the evolutionary shift in the individual system-environment relationship, so that the direct(More)
Attempts to explain the origin of macroevolutionary innovations have been only partially successful. Here it is proposed that the patterns of major evolutionary transitions have to be understood first, before it is possible to further analyse the forces behind the process. The hypothesis is that major evolutionary innovations are characterized by an(More)
The history of scientific inquiries about the organism within medicine and biology is characterized by controversies about the adequate research methods and forms of explanation. These controversies continue well into our time. In different variations the more mechanistic approaches are opposed to the more vitalistic approaches, reductionistic approaches(More)
The question of specific properties of life compared to nonliving things accompanied biology throughout its history. At times this question generated major controversies with largely diverging opinions. Basically, mechanistic thinkers, who tried to understand organismic functions in terms of nonliving machines, were opposed by those who tried to describe(More)
Recent developments in evolutionary biology, comparative embryology, and systems biology suggest the necessity of a conceptual shift in the way we think about organisms. It is becoming increasingly evident that molecular and genetic processes are subject to extremely refined regulation and control by the cell and the organism, so that it becomes hard to(More)
