The ESS parameter indicated that the parameter (Threelength) for each model was sufficiently explored (X>200). To produce the demographic reconstruction and to calculate the ESS, we used Tracer v1.5.0, allowing 10 steps in Nτ over time. According to the Bayesian analysis, the tMRCA to BSP (strict/relaxed) were estimates in the decade of the 1960s (1963).
