A [[monophyletic]] Pancrustacea has been supported by several molecular studies,{{r|Regier2005|Regier2010|Shultz2000|Giribet2000|Nardi2003}} in most of which the subphylum Crustacea is [[paraphyletic]] with regard to hexapods (that is, that hexapods, including insects, are derived from crustacean ancestors). |

The evidence for this clade derives from molecular data and morphological characteristics. The molecular data consists of comparisons of [[Cell nucleus|nuclear]] [[ribosomal RNA]] [[gene]]s, [[mitochondria]]l ribosomal RNA genes, and [[protein]] coding genes. The morphological data consists of [[ommatidia]]l structures (see ''[[arthropod eye]]''), the presence of [[neuroblasts]], and the form and style of [[axonogenesis]] by pioneer [[neuron]]s.{{r|Richter2002|Dunn2008}} |
