Figure 6 in Reconstructing the Anomalodesmata (Mollusca: Bivalvia): morphology and molecules

Figure 6. Maximum Likelihood tree found with the constraint for monophyletic septibranchs applied. The –lnL of 19955.13 compares to 19953.80 of the unconstrained ML tree (delta –lnL = 1.33, p = 0.448). Estimated model parameters: gamma shape parameter for four categories of site rates alpha = 0.383579, proportion of invariable site = 0.189587, empirical nucleotide frequencies: ~A = 0.24431, ~C = 0.223609, ~G = 0.2775, ~T = 0.2421, relative rate parameters: r(AC) = 0.97176, r(AG) = 1.68869, r(AT) = 0.80549, r(CG) = 1.29472, r(CT) = 3.04142, r(GT) = 1.0. Arrows indicate the 'thraciid' (T) and 'lyonsiid' (L.) lineages.
