From: Rapid divergence of a gamete recognition gene promoted macroevolution of Eutheria
Phylogenetic analysis of Cytb DNA sequence divergence. Shown is the gene tree constructed by Bayesian analysis of 119 aligned Cytb sequences, with Chinese soft-shelled turtle as outgroup. Red dots denote nodes lacking statistical support (47/118 = 39.8% unsupported). Note the many discrepant groupings, including absence of monophyly for Superorders Euarchontoglires and Afrotheria, grouping of Superorder Xenarthra with Superorder Laurasiatheria rather than branching basal to all other Eutherian Superorders, and grouping of mammalian Infraclasses Monotremata with Eutheria rather than basal to Marsupialia
