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

    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 e...

    A rare lobopod with well-preserved eyes from Chengjiang Lagerstätte and its implications for origin of arthropods

    The origin of arthropods has long been one of the most hotly-debated subjects. Arthropods used to be thought closely related with annelids, but the two groups are now believed to be separated into two major re...
