Editing Craniate (section)

==Classification==
Below is a [[phylogenetic tree]] of the phylum [[Chordata]]. Lines show probable evolutionary relationships, including extinct taxa, which are denoted with a [[Dagger (typography)|dagger]], †. Some groups in this tree ([[lancelets]] and [[tunicates]]) are invertebrates. The positions (relationships) of the lancelet, tunicate, and craniate clades are as reported.<ref>{{Cite journal | title=The amphioxus genome and the evolution of the chordate karyotype
