Time-homogeneous consensus tree. Consensus tree from 18,000 sampled trees of the time-homogeneous substitution process inferred by PHASE-2.0, graphically processed with Adobe Illustrator CS2. Support values below 0.70 are not shown (nodes without dots), nodes with a maximum posterior probability (pP) of 1.0 are represented by dots only. The grey dot indicates the clade containing all hexapod taxa including Hutchinsoniella (Crustacea) + Lepisma (Zygentoma); its node value is pP 0.58. Quotation marks indicate that monophyly is not supported in the given tree.
