If you'd asked me some years ago, I would have said it's obvious: vertebrates must be more closely related to the cephalochordates—they have such similar post-cranial anatomies—while the urochordates are the weirdos, the most distant cousins of the group.

Recent developments in molecular phylogenies, though, strongly suggest that appearances are deceiving and we vertebrates are more closely related to the urochordates than to the cephalochordates, implying that some interesting evolutionary phenomena must have been going on in the urochordates.

That makes the urochordates a particularly interesting group to examine.

Did you know the famous paper that originally said that urochordates and vertebrates are sister groups DID NOT INCLUDE THE HEMICHORDATES and further also showed as a result that CEPHALOCHORDATES AND ECHINODERMS are… SISTER GROUPS?

For example, whereas in urochordates the ancestral Hox cluster has fragmented, the individual genes show high levels of sequence identity and similar A/P-restricted patterns of expression to their orthologs in other bilaterians.

More recently, multiple gene losses have occurred independently in some lineages (nematodes, insects, urochordates), the same groups that have also lost genes of another type of E3s (RBR family).
