Figure 7 in Phylogenetic affinities and taxonomy of the Oligocene Diomedeoididae, and the basal divergences amongst extant procellariiform birds
Figure 7. Phylogenetic trees resulting from analyses of the character matrix in Appendix 2 with different outgroup taxa. A, strict consensus tree of six most parsimonious trees [length = 108, consistency index (CI) = 0.60, retention index (RI) = 0.71] with only Gaviiformes as outgroup taxon; as detailed in the Discussion, this is the phylogeny preferred in the present study. B, single most parsimonious tree (length = 110, CI = 0.63, RI = 0.76) with Sphenisciformes and Gaviiformes as outgroup taxa; the same tree topology resulted from an analysis with outgroup comparisons based on Sphenisciformes alone. Apomorphies and character states are listed on the internodes (numbers refer to the character list in Appendix 1); filled circles represent strict apomorphies, open circles homoplastic ones. Bootstrap support values are given next to the internodes.
