Y-chromosome phylogeny of macaques. Maximum likelihood phylogenetic tree derived from ~2850 bp of the SRY and TSPY genes to confirm provenance of cynomolgus macaques in the original Goswami et al. [28] study. Notable clades are highlighted according to previous work on the subject [25, 44] and additional macaque groups are identified based on Tosi et al. [44] and defined in supplemental Additional file 2: Table S2, including the monospecific Arctoides (M. arctoides) and Sylvanus (M. sylvanus) groups, the Sinica group, and the Silenus group. Animals from Goswami et al. [28] are highlighted in red and fall within the “Continental” clade of cynomolgus macaques that includes those from Mauritius, supporting that they derived from Mauritius.
