Maximum-likelihood analysis Best-fit maximum likelihood tree calculated under the GTR + Γ + G time-reversible model for nucleotide substitutions. The two outgroups (Alectura and Chauna) are combined in the tree and the branch leading to them is not drawn proportional to the number of substitutions. The Bayesian inference analysis resulted in the same tree topology. The numbers indicated on branches refer to nodal support values estimated in the Bayesian analysis.
