Figure 13. Comparison of phylogenies derived from morphological and combined data sets. A, Strict consensus for molecular data (581 steps; CI = 0.801); B, Strict consensus tree for combined morphological and molecular data sets (611 steps, CI = 0.861). Bootstrap values are given above each internode. Note that the relationships within the slender-bodied clade are identical in the two trees, but relationships within the deep-bodied clade differ in the two trees.
