Background: Estimating divergence times in phylogenies using a molecular clock depends on accurate modeling of nucleotide substitution rates in DNA sequences. Rate heterogeneity among lineages is like
Node age estimates from Beast analyses are shown; estimates based on island calibrations are presented in columns 2 and 3, estimates based on a divergence rates are presented in columns 4 and 5. Ances
Node ages (Ma) and 95% highest probability density (HPD) and credibility (CI) intervals estimated under rate variation and autocorrelation relaxed molecular clocks with BEAST and Multidivtime programs
The estimation of phylogenetic relationships and divergence times among a group of organisms is a fundamental first step toward understanding its biological diversification. The time of the most recen
