ML phylogeny and TMRCA of the mitogenomes analyzed in the present study and Mesoamerican chronology. The horizontal color rectangular boxes right below the tips of the phylogeny indicate the continental geographical location where the mitogenomes were sampled (as in Figures 4 and 5), while the color rectangular boxes in the bottom indicate the continental geographical location of the respective clades according to inferences carried out jointly on mitogenomes and control region data.
