Taxic homology

Patterson s Milestone Taxic and Transformational Homology Recognizing Homologues and Transformational Homology... 

Remane s three auxiliary criteria (see above) are concerned with the coincidence of characters (Wagner, 1986 152), considered related to, or even synonymous with, Patterson s congruence test (Patterson, 1982 Bock, 1989 336 Schmitt, 1995 Haszpruner, 1998) and often associated with the discovery of taxic homology (Donoghue, 1992 173 Brower and Schawaroch, 1996 Sluys, 1996 Haszpruner, 1998 Donoghue and Ree, 2000 760). That viewpoint presupposes that taxic homology is discovered from data organized prior to analysis. 

Patterson s taxic homology (1982) is represented in one of Hemiig s early diagrams (Figure 9.8). 

Taxic homology = synapomorphy = taxon. If homology = synapomorphy, then... 

Taxic homology = taxon. That equation is possible only to the extent that the homologue... 

I identified three milestones in the development of the concept of homology (1) Owen s distinction and clarification of homology and analogy (and homologue and analogue), (2) Patterson s distinction between taxic and transformational homology, and (3) Nelson s introduction of the concept of relationship into studies of homology.
