Описание: Those who wish for permanence in classifi- cation must pay the price of stasis - as if for- ever condemned to confound whales with fish. M. T. Ghiselin 1981, p. 283 Scientific argument is a debate concerned with the solution of unresolved problems. Before continuing with the phylogenetic system of the Metazoa this foreword gives me the opportunity to discuss some controversial ques- tions, to state selected positions more precisely and to remedy omissions. I would like to draw special attention to serious problems for phylogenetic systematics resulting from the inevitable confrontation with the current rules of nomenclature 1. In carrying out this debate, I hope not to lose the goodwill of those readers who are experts within the first few pages. A textbook for students? - Critics who ask that question and answer in the negative probably underestimate the open-mindedness of young people who are not troubled by, or can easily free themselves from, the restraints and arbitrariness of traditional classifications - and to whom systematics is offered as a scientific product in such a form that arguments for every single decision are comprehensible and checkable and can therefore be fully analyzed.
Описание: The system of multicellular animals presented here is an alternative to the traditional classification system which still operates. This volume covers the metazoa from the molluscs up to the arthropods.

Описание: The turtle, toothless, soft bodied, enclosed in boney, shell, is primordial and invincible, slow and changeless. Locked into turtles of time and tradition, inertia and ignorance, darkness and fear, we cajole and pull, struggle and push until we learn that ideas set us free. Fairbanks, Alaska University Campus Sculpture LIz BIESOT 1985 The evolutionary order of organisms as a product of Nature and its repre- sentation in a phylogenetic system as a construct of Man are two different things. The order in Nature consists of relationships between organisms. It is the result of an historic process that we call phylogenesis. When working with this order we must clearly differentiate between its identification and the subsequent description of what has been identified. When identifying the order we are placing ourselves in the framework of "hypothetical realism" (Vol. 1, p. 11); it is principally impossible to de- termine how well or how poorly the real world and our cognitive appara- tus match. For phylogenetics as an historicaUy directed discipline, how- ever, the following limitation is more relevant. We cannot demonstrate ex- perimentally wh ether or not that which we have interpreted from the prod- ucts of phylogenesis corresponds to facts of (hypothetical) reality.
