Maximum-likelihood phylogeny of the 70-taxon TB73 data set. This data set was composed of up to 668 bp. Among the ingroup, 60 characters were parsimony-informative. Estimated ML model parameters conform to the GTR+G model of sequence evolution. -ln L = 2197.656119, rate matrix: A-C = 0.96077, A-G = 2.179468, A-T = 1.20066, C-G = 0.881978, C-T = 2.497604, G-T = 1. Base frequencies: A = 0.29, C = 0.18, G = 0.20, and T = 0.33, and γ-shape parameter = 0.741199. Thick branches indicate nodes with ≥ .95 BPP and ML and MP bootstrap values ≥ 70.
