Figure 2 in Molecular phylogeny of Anomalodesmata (Mollusca: Bivalvia) inferred from 18S rRNA sequences

Figure 2. Strict consensus tree of 22 most parsimonious trees using all alignment positions of the 18S rRNA data set. Bootstrap values (above branches) refer to 1000 replications, maximum-likelihood puzzling values (below branches; values lower than 30 not given) refer to 100 000 puzzling steps. A, subtree showing the position of Anomalodesmata among the Heterodonta. B, subtree of the Anomalodesmata. Pha., Pharidae; Ven., Veneridae. Asterisks mark species of the polyphyletic Myoida. Arrowheads indicate the anomalodesmatan nodes collapsing when 506 positions of uncertain alignment in the
