Evidence for gill slits and a pharynx in Cambrian vetulicolians: implications for the early evolution of deuterostomes

BACKGROUND: Vetulicolians are a group of Cambrian metazoans whose distinctive bodyplan continues to present a major phylogenetic challenge. Thus, we see vetulicolians assigned to groups as disparate as deuterostomes and ecdysozoans. This divergence of opinions revolves around a strikingly arthropod-...
