Summary of results of phylogenetic analyses with and without predicted ancestors (PAs) under maximum parsimony (MP) and maximum likelihood (ML). Fit relative to the molecular phylogeny of Meredith et al. was assessed using the normalized Robinson–Foulds metric (nRF), the SPR distance (SPRd) and the distortion coefficient (DC). nRF values closer to 0 and SPRd and DC values closer to 1 represent better fit. For the MP analyses that recovered more than one most parsimonious tree (MPT), the number of MPTs is indicated. Also indicated is whether the analyses recovered six superordinal clades found in the ‘molecular consensus’, with standard bootstrap (BS) and ‘transfer bootstrap expectation’ (TBE) values given in brackets.
