FIG. 3.

Phylogenetic reconstruction of the “chimpanzee-plus” mtDNA genomes alignment. mtDNA sequences (10,743 bp) were analyzed using the BMCMC approach in BEAST. The MCC tree is presented, with the Pan troglodytes clade shown boxed and enlarged. The subspecies of each sample was determined by mtDNA haplotype and is indicated by color. Posterior probabilities of well-supported nodes are represented by filled circles (90–99%) or asterisks (100%). Open circles indicate fossil-calibrated nodes. The P. t. troglodytes lineage is paraphyletic, and one of its samples (WE464) was collected in the P. t. ellioti range (see text). Specific details of the node date estimations are included in Table 2.
