Figure 5 in REVIEW Vertebrate origins are informed by larval lampreys (ammocoetes): a response to Miyashita et al., 2021

Figure 5. Phylogenetic tree of early vertebrate relationships, condensed from that in the target article of Miyashita et al. (2021). Parsimony consensus tree based on 167 morphological characters. 'FYA,' 'FY,' etc. mark my interpretation of how the clades fed: see the Key. The relationships among the lampreys might alternatively be those in Figure 7B. Antiarcha and Arthrodira are two groups of jawed placoderms, which come out as paraphyletic in the tree.
