Results from various analyses of Dataset2 (node numbers refer to Figure. 3): branch support, mean node ages, the 95% highest posterior density values (HPD; depicted as grey bars in Figure. 3) from analyses using a relaxed clock with lognormal and exponential settings, and inferred ancestral areas at internal nodes (RASP) and branches (DEC; relative probability of an area reported for branch leading to numbered node). Areas with a relative probability of > 0.01 in the DEC and RASP analyses are reported. Unit areas: A = western North America, B = eastern North America, C = western Eurasia, D = eastern Eurasia, E = southern South America, F = Australia + New Zealand, G = Old World Tropical.
