Alternative topology with the sable and roan antelope as sister taxa. The percentage of gene trees supporting each topology is shown above each tree. Numbers next to nodes indicate the 95% credibility intervals of the divergence time in million years. Numbers above the timescale represent the mean of the respective divergence time of that node. The maximum likelihood phylogenies were fossil calibrated using a uniform prior between 3.6 and 4.5 Ma for the Oryx/Hippotragus split with a soft maximum bound. For further explanations, see Bibi.
