Figure 4

ML-based ancestral character state reconstructions of mt genomic characteristics on the tree presented in Figure 1: (A) genes on one strand vs. genes on two strands, (B) presence/absence of full size atp8 gene, (C)nd4/nd4l separated by genes vs. nd4/nd4l not separated by genes, (D) presence/absence of an extra trnM gene. For each of these four mt genomic characteristics, the indicated character state for the unionoid bivalve ancestor is identical to that indicated for the molluscan ancestor. "Stars" indicate nodes for which the character state designations were not statistically significant (all other nodes were statistically significant).
