Figure 12 in Phylogeny of Veneroidea (Mollusca: Bivalvia) based on morphology and molecules

Figure 12. Molecular phylogeny of Veneroidea: a 50% majority-rule consensus tree based on a Bayesian analysis of the 16S rRNA, cytochrome oxidase I, 28S rRNA, and histone 3 data sets for a pruned selection of 56 taxa (59 sequences) with sequences> 1200 bp in length. Branch lengths and posterior probability values based on a sampling of 29 001 trees (3 000 000 generations; sample frequency = 100; burn-in = 1000; heat = 0.5). Symbols and conventions as in Figure 7; bootstrap proportions (≥ 70%) are based on a parsimony analysis (250 replicates, 10 random sequence additions; equal weighting). In Corbicula, Mercenaria, Neotapes, and Ruditapes philippinarum, GenBank sequences represent concatenated sequences of independent GenBank submissions for some or all genes. For some other taxa (Arctica and Calyptogena), sequences represent a mixture of GenBank and newly acquired sequences for the same species.
