Bayesian consensus tree for mtDNA control region sequence data. Values above the branches are Bayesian consensus values. Parentheses indicate additional sites where a haplotype was recovered. Western clade haplotypes (white bar) form a classic star-like topology with most haplotypes coalescing along the backbone of the clade. Haplotypes from the eastern clades (black bar) do not form a star-like topology and are both deeply divergent from all western clade haplotypes as well as divergent from each other. This tree is unrooted and is drawn with the eastern clades as basal to illustrate the monophyly of the western clade. The tree could also be drawn with the western clade as basal.
