We recently acquainted with computational phylogenetic methods on lexical data to probe mediator two scenarios for the peopling of the Pacific. Our analyses of lexical details supported a pulse-pause synopsis of Pacific settling in which the Austronesian speakers originated in Taiwan slip 5,200 years ago and double-quick spread with the aid the Pacific in a series of spread pulses and establishment pauses. We claimed that there was squiffed congruence interceder accustomed language subgroups and those observed in the lingo phylogenies, and that the estimated age of the Austronesian stretching at 5,200 years ago was regular with the archaeological evidence. However, the congruence internuncio the argot phylogenies and the evidence from recorded linguistics was not quantitatively assessed using tree weighing metrics. The robustness of the divergence delay estimates to different calibration points was also not investigated exhaustively. Here we talk these limitations by using a businesslike tree kinship metric to add up the similarity messenger the Bayesian phylogenetic trees and the subgroups proposed by true linguistics, and by re-estimating the age of the Austronesian bourgeoning using no more than the most muscular calibrations. The results show that the Austronesian language phylogenies are decidedly congruent with the usual subgroupings, and the date estimates are sound even when adjusted using a restricted set of true calibrations.
