Summary for E2 substitution rate estimations.

Substitutions rate for E2 data sets. Results correspond to Bayesian Skyline Plots run under appropriate model of nucleotide substitutions: GTR+Γ+I for CdE+OLC and CdE data sets and HKY+Γ+I for OLC data set. Relaxed clock model (uncorrelated lognormal) was used. The tMRCA for each data set was set as prior with gamma distribution (Shape; Scale): 18.03; 7.41 for CdE+OLC data set; 17.45; 6.36 for OLC data set; 16.42; 6.46 for CdE data set. CdE, Cruz del Eje E2 sequences, OLC, Other Locations of Córdoba E2 sequences. CdE+OLC, sequences from CdE and OLC data sets. s/s/y: substitutions per site per year; HPD-95%, High Posterior Probability Density 95%.
