Figure 4. A, phylogeny inferred here from 47 in New morphological evidence supports congruent phylogenies and Gondwana vicariance for palaeognathous birds

Figure 4. A, phylogeny inferred here from 47 morphological characters (core character group), consensus tree from TNT [four most parsimonious trees (MPTs) with explicit enumeration] and PAUP* (12 MPTs with branch-andbound), with dates based on Gondwana separations (Scotese, 2001). Best tree length 96 steps, consistency index = 0.7624, retention index = 0.7798, rescaled consistency index = 0.5945. B, 50% bootstrap majority-rule tree from PAUP*. Maximum trees 10 000; replications 1000; tree bisection-reconnection algorithm. C, phylogeny from complete character set in TNT (two MPTs). Bootstrap support values> 50% are indicated.
