Category:ParaHoxozoa

= ParaHoxozoa = The ParaHoxozoa are a proposed basal Diploblast/Eumetazoa clade as sister of the Ctenophora. It consists of the Triploblasts/Bilateria as well as the Placozoa and Cnidaria.[1][2][3][4][5][6][7]

Characteristics
The Parahoxozoa group was defined based on the presence of several gene (sub)classes (HNF, CUT, PROS, ZF, CERS, K50, S50-PRD), as well as Hox/ParaHox-ANTP from which the name of this clade originated. It was later proposed[8][9] and contested[10] that a gene of the same class (ANTP) as the Hox/ParaHox, the NK gene and the Cdx Parahox gene, is also present in Porifera. Nevertheless, the Parahoxozoa as originally defined without Porifera may be a monophyletic clade, and is continued to be used as such.[4]
