 Chordate

A member of the animal group including vertebrates, tunicates and cephalochordates, with a notochord as part of the characteristic developmental body plan.

Chordate is a sad clade.

You read the name and think: hmm, neural cords!

Yup. That's your cousin. And it's a much closer cousin than something like arthropods, which at least have heads eyes and legs like you.

Convergent evolution is crazy!
