What is a characteristic shared by all chordates the phylum in which humans are classified?

All chordates are deuterostomes, meaning that in all chordates, the anus develops first during embryological development.

All chordates are bilaterally symmetric.

Most chordates have a complete digestive tract, and a body cavity. Note: not all chordates have these features, but it is believed that their absence in some chordates is secondary.

All chordates are of course animals and eukaryotes.
