Figure 10. Parsimony analysis of living and extinct hystricognathous rodents, based on 118 morphological characters, largely from the dentition, 77 of which were treated as ordered.

Figure 10

(A) Strict consensus of 10 MPTs recovered by parsimony analysis with all characters equally weighted. Tree length (TL) = 907, consistency index excluding uninformative characters (CI) = 0.2892, retention index (RI) = 0.5821, rescaled consistency index (RCI) = 0.1720. (B) Adams consensus of 119 MPTs recovered by parsimony analysis with transitions between “fixed” and polymorphic states weighted as a half-step; dashed branches break down in the strict consensus. TL = 595, CI = 0.3109, RI = 0.5769, RCI = 0.1847. (C) Maximum agreement subtree of all 119 trees summarized in (B). Taxon names are colored according to their geographical location. Bootstrap support values, based on 1,000 pseudoreplicates, are found above or below branches that are supported at a level >50%.
