  1. 1 The most recent common ancestor (tMRCA) is the median Bayesian estimate in years ago (ya); 95% HPD intervals are given in parentheses.
  2. 2 The tMRCA for this node was constrained by using a uniform distribution prior of 40,000–60,000 ya.
  3. 3 The tMRCA for this node was constrained by using a uniform distribution prior of 12,000–30,000 ya.
