Chordates. As shown in the supra figure, all Notochord Brain vertebrates are be within the Chordata phylum. All ch! ordates evolved from an ancestor that had a impressible rod (called a notochord) along the dorsal side (back) to offer up animation for the skeleton and muscles. All chordates share a Anus common internal carcass plan.
