Figure 4

Time tree phylogeny depicting divergence time estimate based on primary and secondary calibration using BEAST2 v2.6.6. Red dots indicate the nodes with calibrations. Node labels indicate the median estimated divergence time, blue bars indicate the 95% HPDs. Tip labels highlighted in red indicate red junglefowl. Tree file was visualized and edited in FigTree v1.4.4. (http://tree.bio.ed.ac.uk/software/figtree/).
