FIG. 46. Minimum-step cladograms for eight basic taxa of iguanines, resulting from a preliminary 

 analysis of 29 characters (Table 7). Two different cladograms (A and B) account for the taxic distribution of 

 derived characters with 46 character transformations. Synapomorphies of the numbered nodes and basic taxa 

 are given in the text.
