  1. Values were calculated by combining results from each of the 100 clades into nine larger groupings. 'Proportion of species with data' is calculated as the number of species in each group represented by at least one sequence in our dataset, divided by the total number of species described for that group. Resolution is calculated as the number of nodes resolved for each group divided by the number of nodes in a fully bifurcating version of the same tree for 50% and 95% bootstrap (BP) majority rule consensus trees, respectively.
