Ultrametric time-calibrated tree for combined DNA markers (MIT-NUC dataset) of Carabidae. Analyses were conducted in BEAST including outgroups, partitioning by gene, with two partitions for coding genes (first and second codon positions together) and applying a relaxed ULN clock. Node support is given as Bayesian posterior probabilities. Grey bars on nodes represent the 95% confidence intervals for node ages in Ma. The vertical grey bar shows the 95% HPD interval for the split between Carabus and Calosoma.
