In this study the relationship between functional morpholoy and evolutionary biology is analysed by confronting the main concepts in both disciplines.Rather than only discussing this connection theoretically, the analysis is carried out by introducing important practical and experimental studies, which use aspects from both disciplines. The mentioned investigations are methodologically analysed and the consequences for extensions of the relationship are worked out. It can be shown that both disciplines have a large domain of their own and also share a large (...) common ground. Many disagreements among evolutionary biologists can be reduced to differences in general philosophy (idealism vs. realism), selection of phenomenona (structure vs. function), definition of concepts (natural selection) and the position of the concept theory as an explaining factor (neutralists vs. selectionists, random variation, determinate selection, etc.).

In biology, and particularly in morphology, various types of explanation are found,e.g. causal, teleological, historical, etc.In this article an attempt has been made to analyse the relations between the various explanations to strive for an encompassing explanatory theory.The general structure of the explanatory theories appeared to be very similar, but the terms defining the phenomena and the types of the relations within the theories differ. To obtain a unifying theory it is necessary to develop methods to connect or transform the (...) different elements.An important aspect is that the definition of selected phenomena depends on the explanation pursued.

An initial investigation of controversies and differences in opinion in the various schools of functional anatomy is presented by listing the methodology problems.The possibilities and limitations of functional anatomy are derived from the successive steps in the procedure in a functional anatomical investigation.Starting from the holistic approach as introduced byVan der Klaauw, the main problems of defining the term functional component and the applied methods are discussed.Two principal methods are presented, of which the limitations are considered. The various aspects where (...) new information is needed are illustrated in the example of bone mechanics. The advantages of an approach from a pattern of the interrelations are mentioned. (shrink)

An introduction to the 19th Lochmühle conference on ‘Architecture in living structure’, organized by P. Dullemeijer, W.F. Gutmann and G.A.

A good division of biology is important for clarity of thought, presentation of the problems and nowadays also for science policy. Various classifications are in use, depending upon different parameters. A division can be based on objects and on aspects. A modern classification on objects is based on the levels of organisation. Methodological principles play a role in the background.
