Figure 1

mtDNA phylogeny of macaques. Maximum likelihood phylogenetic tree derived from a ~835 bp segment of the cytochrome b gene to confirm provenance of cynomolgus macaques in the original Goswami et al. [28] study. Animals included in the analysis are referenced in Additional file 1: Table S1. Notable macaque clades are highlighted according to previous work on the subject [46]. Animals from Goswami et al. [28] are highlighted in dark red and fall wholly within the Mauritian cynomolgus macaque group, supporting that they derived from Mauritius.
