Red arrows show the calibration points for molecular dating. Divergence time and the timeline are indicated in million years ago. WebNov 1, 2015 · The later divergence (“Gomphotheriidae”-Elephantoidea) date is slightly older than the value obtained in the molecular-only analysis (∼13.5 Ma; Table S2), although their confidence intervals are largely overlapping. Also, previous research has shown that total evidence tip-dating and morphological clock approaches can provide slightly ...

Webdivergent evolution: the process by which a species or gene product gives rise to two or more different products. WebApr 25, 2016 · The divergence times estimated from the TD analyses were older than those estimated from FBD (Fig. 4, Table 4), and the TD dates were older than previously inferred using node dating . The results of the FBD analysis with wide and fixed date priors were comparable, with a mean difference in the median estimates of 0.53 Ma, and the 95% … WebJul 1, 2001 · Fig. 1.—Ninety-five percent confidence intervals for the divergence time of a pair of taxa obtained by different methods. = true mean and confidence interval as determined by simulation; ★ = mean and confidence interval for fixed mutation rate; = mean and confidence interval according to Steel, Cooper, and Penny (1996) porsche dealers near me 55401
