Feb 26, 2015 if building the supertree with all of the inputs except for the fact that y is pruned from t returns a supertree in which y is monophyletic, then we say that the analysis supports the monophyly of y.
However, comparative studies depend on phylogeny to control for the effects of shared evolutionary history. We compare our phylogenetic trees to previous estimates of mammalwide phylogeny and divergence times, finding that 1 node ages are broadly concordant among studies, and 2 recent tiplevel rates of speciation are estimated more accurately in our study than in previous supertree approaches, in which unresolved nodes led to branch. Despite concerns over the robustness of supertrees see discussion, we believe that it provides a valuable framework for testing numerous evolutionary hypotheses relating to the diversity of behaviour, ecology and lifehistory of the charadriiformes.
