Based on likelihood analyses of 62 nuclear protein-coding genes. Branch lengths are proportional to the amount of inferred sequence change, with the topology and analytical conditions identical to the degen1 analysis in Fig. 1. Line drawings of representatives of the major taxonomic groups show the morphological disparity across Arthropoda. Scale bar, nucleotide changes per site.
