	Uniramia - Wikipedia, the free encyclopedia
		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).
		In Manton's original proposal, the Uniramia also included the Onychophora (velvet worms), but the discovery of fossil lobopods that are intermediate between onychophorans and arthropods is strong evidence for the two groups being separate.
		The Crustacea were generally considered the closest relatives of the Uniramia, and sometimes these were united as Mandibulata.

		The Uniramia are a group of arthropods, comprising the Hexapoda (insects and allies) and Myriapoda[?] (centipedes, millipedes, and related forms).
		The Crustacea are generally considered the closest relatives of the Uniramia, and sometimes they are united as the Mandibulata.
		However, new studies suggest that the Myriapoda are not be closer related to the Hexapoda than the Crustacea, in which case the Uniramia would be abandoned.

	Uniramia
		Manton as part of a paradigm of Arthropod polyphyly, the Uniramia ("single branch") are identified by their single pair of preoral antennae, possibly homologous with the antennae of trilobites.
		Recently however the status of the Uniramia as a valid taxon has been increasingly questioned and evidence presented suggesting the Crustacea are the stock from which the Hexapoda arose (i.e.
		A limited version of the Uniramia, the Atelocerata, includes only euarthropodic Uniramia, but this would also be invalidated if the Pancrustacea theory turns out to be correct.

	Uniramia - Wikipedia
		The legs on the rest of the body are typically uniramous, that is, have a single walking branch with no gill branch as in other arthropods, which gives the group its name.
		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.
		Within the Arthropoda, the Uniramia are generally considered the sister group to the Crustacea, but this is not quite so certain, and in proposals where the arthropods are polyphyletic they are often taken to be closer related to the non-arthropod Onychophora.

		The Uniramia is a mainly abandoned taxon of arthropods,comprising the Hexapoda (insects and allies) and Myriapoda (centipedes, millipedes, and related forms).
		The Crustacea were generally considered theclosest relatives of the Uniramia, and sometimes were united as the Mandibulata.
		However, new studies suggest that the Myriapodaare not more closely related to the Hexapoda than the Crustacea, causing the Uniramia taxon to be abandoned.

		The Uniramia are primarily terrestrial, although many species have secondarily invaded freshwaters, - and a few have reinvaded the marine environment.
		However, the group is thought to have originally evolved in the marine environment as benthic organisms.
		The uniramia is an extremely diverse and ecologically important group, but because it is not abundant in marine environments will not be treated further in this overview.

		The Uniramia includes the insects and several smaller groups of related organisms.
		Note that most current classification schemes do not include the myriapods (centipedes and millipedes) in the Uniramia, instead placing them in their own subphylum, the Myriapoda (meaning "many-legged").

		The Hexapoda, by far the largest taxon of the Uniramia, contain the Collembola, Protura, Diplura and Insecta.
		The name Uniramia refers to the fact that the appendages are basically unbranched and there is no evidence that they were derived from a branched condition.
		This subphylum consists of arthropods with one pair of antennae and with mandibles.

		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.
		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].
		The above presents a paleontological perspective, and retains the Uniramia.

		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.
		It will be recalled from the previous section that the definitive mouthpart in tracheate arthropods (Uniramia) are the mandible, supported by two smaller appendages, the 1st and 2nd maxillae.
		Crustaceans and uniramians collectively are often called mandibulate arthropods, and in both groups the mandibles are derived from appendages of the 2nd somite of the head.

		Although the very first members of the class Insecta were close behind the chelicerates in their forays Out of the water, for example, insects as we know them did not definitively appear for another 100 million years (near the end of the Carboniferous period).
		The earliest uniramia to evolve and leave fossil records of themselves were the centipedes (2500 modern species) and millipedes (10,000-50,000 modern species).
		Of all the living arthropods, these classes show the most superficial resemblance to their probable onychophoran-like ancestors.

		Most would agree that the use of polyphyletic 'concept' names, such as Uniramia, should be discontinued.
