Types and the Geoffroy-Cuvier debate: a crossroads in evolutionary morphology,common anatomical design, held sway among pre-Darwinian morphologists. In recognizing equivalences of structures, these early morphologists used the type or archetype, rather than any notion of descent from a common ancestor, to explain morphological similarities in apparently unrelated organisms.

Archetypes and homology: the establishment of evolutionary developmental biology,eas were rapidly assimilated into Britain as British scientists responded to the implications of the Geoffroy-Cuvier debate (section 4.2). A lasting impact was to be made in the separation of homology from analogy advocated by Sir Richard Owen (section 4.3). Darwin took account of these developments

,: fundamental body plans,ion, structure, form; ., plan, design, intention). The term was introduced into morphology by Woodger (1945) and although more or less assimilated into biology, it has not been incorporated into general use outside of science, unlike terms such as ‘evolution’ or ‘species’, or phrases such as ‘surviv

Homology and the evolution of development,bular morphology, has profound implications for our notions of homology. The implications are that morphological changes that are identical at the level of structure can arise by selection activating different developmental processes i.e. structures that we regard as homologous in the adult can aris

Evolution and development: principles and processes,rinciples and the concepts into processes. Aside from the symmetry that this establishes, which is satisfying, it is obviously important to summarize where evolutionary development biology is and to project where this subdiscipline is likely to take us as we move through the 1990s.

Kuhn and Relativism: Is He or Isn’t He?having offered a relativistic conception of scientific knowledge. Yet he has disavowed relativism, and has made several attempts to clarify his position regarding relativism and related issues. As we shall see, relativism is for Kuhn bound up with a host of such issues, especially those concerning t
