This phylogenetic hypothesis shows the major clades of chordates in relation to the other main deuterostome clade, echinodermata. derived characters are listed for selected clades; for example, only gnathostomes have a jaw. in some lineages, derived traits have been lost over time or occur in reduced form; hagfishes and lampreys, for example, are vertebrates with reduced vertebrae.
based on this phylogeny, which vertebrate groups would you expect to have lungs or lung derivatives?
