Maximum-likelihood phylogeny of the 69-taxon RELN data set. This data set was composed of up to 1104 bp. Among the ingroup, 48 characters were parsimony-informative. Estimated ML model parameters conform to the GTR+G+I model of sequence evolution. -ln L = 2847.341935, rate matrix: A-C = 1.068197, A-G = 3.028768, A-T = 0.454495, C-G = 0.612036, C-T = 2.836311, G-T = 1. Base frequencies: A = 0.32, C = 0.17, G = 0.18, and T = 0.33, and γ-shape parameter = 1416.809681. Proportion of invariable sites (I) = 0.482101. Thick branches indicate nodes with ≥ .95 BPP and ML and MP bootstrap values ≥ 70.
