Table 1 Templeton and Winning Sites tests of alternative topologies, varying placement of the placental root, based on MP with all DNA, indels, and morphology (1–7) and excluding DNA 3rd positions (8–13). Trees 1 and 8 are unconstrained. Competing topologies 2–7 and 9–13 were generated by analysis of the combined dataset with MP constrained to agree with backbone topology supporting Afrotheria [9], Atlantogenata [14], Xenarthra [12], Muridae (Fig. 4B), Erinaceus [16], and Glires [15]. Asterisks indicate rejection of no difference between optimal and competing topology at alpha 0.05.
