It is shown in a literature review, that in the Typostrophic Theory autonomous mechanisms in the organism are considered as the factors which play a decisive role in orienting and controlling the evolutionary process. Selection is a controlling factor of only minor importance. The Synthetic Theory, on the other side, says that phylogenetic changes are not random or controlled by “internal factors” but can always be considered as adaptive remodellings. They are achieved by selection acting on the variation within populations. (...) Ecological, historical and “bautechnische” factors are considered as limiting mechanisms in the evolutionary process. They are discussed in detail in the text. (shrink)

A reconstruction of the anagenetic transformations from fins to tetrapod limbs is represented considering the self-evident mechanical constraints which must have limited the construction and thus the function and the transformation.

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.).
