Figure 6.
Time-scaled phylogenetic tree including several appendicularians, tunicates, and vertebrates, including O. dioica, based on 177 single-copy orthologous protein sequences. The different clades of O. dioica lineages were estimated to have shared a common ancestor ∼25 Mya (95% HPD: 12–41 Mya). The Osaka and Barcelona lineages were estimated to have diverged more recently, ∼7 Mya (95% HPD: 5–10 Mya).
