| Clades | |
Xenambulacraria is a proposed clade of animals with bilateral symmetry as an embryo, consisting of the Xenacoelomorpha (i.e., Xenoturbella and acoelomorphs) and the Ambulacraria (i.e., echinoderms and hemichordates).[1]
If confirmed, the clade would either be the sister group to the chordates (if deuterostomes are monophyletic) or the sister group to all the other bilaterians, grouped together in Centroneuralia (with deuterostomes being paraphyletic).[1][2][3][4]
Although the validity of the clade relies mostly on molecular genetics, pigment cell clusters expressing polyketide synthase (PKS) and sulfotransferase have been proposed as a synapomorphy of Xenambulacraria.[5]
- Other members of the Xenambulacraria
-
Various Acoelomorpha (nemertodermatids). -
Various Hemichordata (enteropneusts).
Phylogeny
The following phylogeny assumes a paraphyletic Deuterostomia, with Xenambulacraria at the base of Bilateria:[4]
