Fig. 1

a ASTRAL topology for 237,364 aligned loci resolving relationships between all known pharyngognathous fish clades and their close relatives. For all parts of this figure, pharyngognathous taxa are denoted in red, while non-pharyngognaths are in blue. Pies represent branch support from black for support values of 1, black and gray for support values greater than 0.9 but less than 1, and solid gray for support values less than 0.9. Images next to the tips of pharyngognathous taxa are microCT reconstructions of their lower pharyngeal jaws. b Our topology from (a) with branch lengths in coalescent units estimated from locus trees in ASTRAL and colored by hemiplasy risk factor. As ASTRAL does not estimate terminal branch lengths, they have been truncated. c Our topology from (a) with branch lengths in coalescent units estimated from site concordance factors (sCF) calculated from IQ-Tree converted into coalescent units with HeiST. As ASTRAL does not estimate terminal branch lengths, they have been truncated. Many pharyngognath lineages are connected by branches with risk factors near 1.
