The ML tree based on amino acid data under the mtREV+I+Γ model. The support values are LR-ELW. In this tree, and in most amino acid phylogenetic analyses, Enhydris plumbea is the sister-group of elapids and colubrids, in contrast to nucleotide analyses, in which E. plumbea is the sister-group of elapids.

The Bayesian MTR+I+Γ tree produced using the program PhyloBayes. The support values are BPP. This analysis gives weak support to the CAT topology (Fig. 3), i.e. boids sister-group to all alethinophidians with the exception of Anilius and Tropidophis, in conflict with node C (Fig. 2). This is in contrast to other MTR+I+Γ analyses that give strong support to node C.
