Bayes factor scores (from Tracer v1.5) from comparisons of alternative tree models for the BEAST divergence time analyses
Tree model estimated mean -lnL S. E. 2 (ln Bayes factor score)
vs. Yule vs. birth-death vs. coalescent (constant size) vs. coalescent (expansion)
Yule −4236.94 ±2.085 −179.978 −160.334 −157.378
birth-death −4146.95 ±1.191 179.978 19.644 22.602
coalescent (constant size) −4156.77 ±1.113 160.334 −19.644 2.956
coalescent (expansion) −4158.25 ±0.912 157.378 −22.602 −2.956

Strong support for the birth-death model was indicated, according to the criterion 2 ln Bayes factor > 10.
