  1. The estimated age (median and 95% HPD of the posterior distribution, in thousands of years) of several key monophyletic clades was calculated assuming that the B. taurus - B. bison divergence occurred 1 MYA [35]. This calibration point is compatible with the demographic expansion detected in cattle mitochondrial data resulting from the Neolithic domestication event. Ages are also calculated assuming that B. taurus - B. bison diverged 2 MY [27]. For comparison, the last column reports the maximum likelihood estimates obtained in a previous study based on the 2 MY calibration point but a fixed topology [28], with standard errors in parenthesis.
