Abstract
THERE have recently been many objections to the orthodox definitions of biological homology in terms of common ancestry on the grounds that such definitions are circular1–4. Parts of two organisms are defined as homologous if they are represented by a single part in a common ancestor. But homology itself is invoked in making this identification of parts of organisms with a part in a common ancestor. Various authors have advocated a return to Owen's5 criterion of homology—“the correspondency of a part or organ, determined by its relative position and connexions, with a part or organ in a different animal”. Jardine6 has formulated a logical model for correspondence of parts of things with respect to a set of relations along lines suggested by Woodger3, and from it has derived a general method for finding such correspondences.
