 | | Tree of life, which is cladistics based and does not use ranks does show hexapoda and myriapoda to have a common source within the arthropoda, but distinct from the rest; it does not use the term Uniramia. |  | | As such, the ITIS system of separate subphyla, though less common, is now more generally acceptable, and since I was the one who balked at it at the first place, I'm taking the liberty of restoring it. |  | | The introduction of the super-class seems to be more linked with those sites that accept Uniramia as a subphylum. |

| | Palaeos Invertebrates: Arthropods - Animals With Jointed Exoskeletons |
 | | One of the more recent theories of arthropod relationships has even involved splitting up the Uniramia by aligning the Hexapoda with the Crustacea rather than the Myriapods (the Pancrustacea hypothesis) [2]. |  | | Others have argued on the basis of molecular and anatomical evidence that the arthropods did indeed evolve from a common ancestor. |  | | Because of all these differences there was for some time a controversy over whether the arthropods constitute a valid monophyletic group, or whether they evolved from separate, even unrelated. |

 | | The uniramous condition probably stems simply from all extant Uniramia being terrestrial or secondarily aquatic. |  | | More work needs to be done on this. |  | | However, some embryological work has suggested that the wings in insects may in fact be homologous to the gill branch in other arthropods, which would require their ancestors to still be aquatic. |

 | | Traditionally, arthropods have been organized into a single phylum (Arthropoda) although some modern specialists recognize no less than three distinct phyla within this group. |  | | Crustaceans differ, however, in several ways, such as having two pairs of antennae, gills instead of trachea, and appendages which are basically biramous (two-branched) instead of uniramous (from which the subphylum name "Uniramia" is derived). |  | | One of the most striking advances made by the arthropods over the annelids is the development of segmented, moveable appendages which are developed from the body wall. |

 | | Traditionally the myriapods have been considered close relatives of the insects and other Hexapoda, and united with them in the Subphylum Uniramia, among which the Myriapoda were treated as a class or superclass. |  | | Four groups of arthropods—the centipedes, millipedes, pauropods, and symphylans—share a number of common features such as a similar body plan consisting of a head followed by an elongate trunk with many legs. |

 | | However, the competing hypothesis — that Crustacea and Hexapoda form a monophyletic group, the Pancrustacea, to which the Myriapoda are the closest relatives — has support from molecular and fossil evidence. |  | | The Uniramia are a major group of Arthropoda, consisting of arthropods with a single pair of preoral antennae and a single pair of legs per segment, namely the Hexapoda (insects and allies) and Myriapoda (centipedes, millipedes, and related forms). |  | | The Crustacea were generally considered the closest relatives of the Uniramia, and sometimes these were united as Mandibulata. |
