From: Rapid divergence of a gamete recognition gene promoted macroevolution of Eutheria
Phylogenetic analysis of Tecta DNA sequence divergence. Shown is the gene tree constructed by Bayesian analysis of 116 aligned Tecta sequences, with Chinese soft-shelled turtle as outgroup. Red dots denote nodes lacking statistical support (27/115 = 23% unsupported). Note the discrepant grouping of Infraclass Marsupialia with Superorders Xenarthra and Afrotheria of placental mammals, rather than basal to all Eutheria. Note also the prevalent lack of support in Afrotheria and at deeper nodes in Superorder Laurasiatheria
