Estimated time since most recent common ancestor (TMRCA) (y-axis) for each H2 subgroup with each other (facets), calibrated by the split time of ~ 163 kya of haplogroup A0 with all other Y haplogroups. All pairwise calculations are filtered to exclude individuals from the same sampling site. The dashed line indicates the mean estimate, and error bars indicate 95% confidence intervals for individual observations.
