FIGURE 1.
Phylogenetic reconstruction and reference timetree of aquatic avian ordinal relationships, including complete species sampling of focal young clade, the flamingos (gray box; crown Phoenicopteridae). Circles designate fossil constraint placement used in divergence time analysis. See text and Table 1 for details of reference analysis. All nodes received complete Bayesian support values; all nodes received >99% bootstrap support in ML analyses, except placement of Phaethontidae + Mirandornithes (85%), and Sphenisciformes + Procellariiformes (75%).
