Itw ill be readily apparent thatav ariety of entomopogia have been devised to show the possible relationships of the hexapod groups Figure 1. Even then, there may be no agreement!
The distinguishing feature of the almost 10,0 species in the class is the presence of diplosegments, each bearing two pairs of legs, formed by fusion of two originally separate somites. Unfortunately, in the case of arthropodst he early fossil recordi s poor.

Some authors have suggested thatthearthropodsaremonophyletic,thatis,haveacommonancestor;othershaveproposed thatthegroupisdiphyletic twomajorsubgroupsevolvedfromacommonancestor ,andyet others believe that each major subgroup evolved independently of the others a polyphyletic origin.
Notsurprisingly,forthe reasons noted above, these views havebeen widely divergent. Indeed,t he extensive cladistic analysiso f Bitsch and Bitsch rejects the monophyly of the Ellipura. Such organisms livedi ns hallow water near thes hore or int he littoral zone.
As they cannot escape from would-be predators by speed, many millipedes have evolved such protective mechanisms as the ability to roll into a ball and the secretion of. The earliest known fossil centipedes, from the Upper Silurian, are remarkablys imilar to some extant species, suggesting that the group may be considerably more ancient. Martins, Damasceno, Awada – Pronto-socorro Pronto-socorro: TheC ollembola, Protura, and Diplura are often placedi nt he taxon Entognatha ta principally because of theu nique arrangement of their mouthparts enclosed withint he ventrolateralextensionsofthehead.
Schemes for the possible relationships of the hexapod groups as envisaged by BoudreauxKristensenand Kukalova-Peck This and other discoveries led Snodgrass to suggest another monophyletics cheme of arthropod evolution Figure 1.

The Protarthropoda gaverise to the Protrilobita from which thet rilobite—chelicerate line developed and the Protomandibulata Crustacea and Protomyriapoda.

After chitinization of the cuticle and loss of all except one pair of tentacles which formed the antennaethe lobopods gave rise to the Protonychophora.
It is believed that the diplosegmental condition enables the animal to exert a strong pushing force withi ts legs while retaining rigidity of the trunk region. In a nutshell, proponents of the monophyletic theory simply point to the abundance of features common to arthropods Section 2 and argue that so many similarities could.
It is, however, only the fossil record that can provide the direct evidence for such processes.

From the protonychophorans developed, on the one hand, the Onychophora and,o nt heo ther, the Protarthropoda inw hich the cuticle became sclerotized and thickened. The monophyleticists, on the other hand, believe that the mandibles of crustaceans, myriapods, and hexapods are homologous.
In most centipedes the legs increase in length from the anterior to the posterior of the animal to facilitate rapid movement.

Nevertheless, a few very earlys chemes should be noted to showhowideas changed as new information became available. The position of the Diplura is questionable, and the group is probably not monophyletic Bitsch and Bitsch, This proposal may be somewhat close to reality as there isn ow fossil evidence that early insects had appendages with side branches, comparablet ot hose crustaceans, entomoolgia urther, the ancestrali nsect leg included 1 segments Kukalova-Peck,andi nE dgecombe, Originally, the major drawback to the scheme was a lack of supporting evidence, especially from the fossil record.

Note also the differing relationships of the Annelida, Onychophora, and Arthropoda. Even after this time the fossil record is incomplete mainly because conditions were unsuitable for preserving rather delicate organisms such as myriapodsa ndi nsects.
