Topic: Uniramia



  
 Talk:Arthropod - Wikpedia
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.

 Uniramia - Wikipedia
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.

Their body forms and ecologies are diverse, though (in contrast to the crustaceans) most unirames are terrestrial.
The phylum Uniramia are characterized by one pair of antennae and two pairs of mouthparts (single pairs of mandibles and maxillae).
The Uniramia includes the insects and several smaller groups of related organisms.

 BIS: Arthropods of Economic Importance - Eurasian Tortricidae > Species: Subphylum Uniramia
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.
The sister groups Hexapoda and Myriapoda form the Uniramia.

 Uniramia
The Euthycarcinoidea would seem to be safely uniramian but their exact relationships are not clear.
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.
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.

However, it is less clear what to do when the simple removal of one or a few unrelated taxa from a formerly polyphyletic taxon, leaving the concept more or less intact, and leaving a monophyletic taxon as well.
Most would agree that the use of polyphyletic 'concept' names, such as Uniramia, should be discontinued.
The last, Atelocerata, seems to enjoy the widest usage, although it appears to have been the last name coined.

 Zolab4 S99
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.

 Myriapoda - Wikipedia, the free encyclopedia
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.

 Uniramia - Wikipedia, the free encyclopedia
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.

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.
They have a unique "proboscis " which they use to pierce and suck liquid from seaweeds and various animals such as hydroids, seaweeds, bryozoans, ascideans, and other invertebrates.

Antennae are jointed, and in crustaceans branching, they generally extend forward of the animal and are known to be sensory organs, although the exact nature of what they sense and how they sense it is often not entirely clear.
Antennae (singular antenna), are the paired appendages connecting to the first (and in crustaceans also to the second) segment of the head of the members of all subphyla of the arthropods except Chelicerata.
Also the members of the order protura (of the subphylum Uniramia) lack them.

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).
Of all the living arthropods, these classes show the most superficial resemblance to their probable onychophoran-like ancestors.
That evolutionary hesitation hasn't proved a handicap in the long run, though: Biologists believe the subphylum Uniramia (including the mammoth class Insecta) contains more living species than all other groups of organisms combined.
