Figure 7From: Novel non-parametric models to estimate evolutionary rates and divergence times from heterochronous sequence data95% bootstrap confidence intervals of substitution rate and root age using maximum likelihood and a strict molecular clock on 50 simulated data sets. The nucleotide substitution rate (a) and root age (b) are inferred using Physher for 50 replicates using a strict molecular clock. Red intervals that do not include the true value (blue line) are shown in red.Back to article page
