Phylogenetic analyses suggest that diversification and body size evolution are independent in insects

Data shown are the results of parametric bootstrap, with 50,000 replicates, Shown are the observed quartile ranges (Obs. QR) and those of the Null tip-randomized data (NULL QR). ^a indicates a significant relationship prior to parametric bootstrap (but not after)
