Figure 2 in Molecular evidence on evolutionary switching from particle-feeding to sophisticated carnivory in the calanoid copepod family Heterorhabdidae: drastic and rapid changes in functions of homologues

Figure 2. Phylogenetic tree based on the 18S + 28S rRNA genes of heterorhabdids. The numbers on branches indicate bootstrap values (maximum likelihood, ML) and posterior probability (Bayesian inference, BI). Two metridinids (Metridia effusa and Pleuromamma abdominalis) were chosen as the outgroup taxa. The star (Node ★) indicates the innovation of a poison-injection system.
