title: Behavior, archetypes and the irreversibility of evolution.
abstract: There is a tendency in modern evolutionary theory to treat organisms as organized by genetic and developmental interactions, in such a way that these play a major role determining the direction of morphological evolution. Alternatively, in this paper behavior is considered as the most fundamental cohesive factor in the morphological evolution of animals. Some phenomena, such as the existence of evolutionary trends, the maintenance of architectural types in certain taxa, and the irreversibility of evolution are discussed in this light.
