Despite these similarities, theC ollembolaa nd Protura are quite distinct bothf rom each other andf rom other hexapods.

Entomology (Gillott, 2005)

The position of the Diplura is questionable, and the group is probably not monophyletic Bitsch and Bitsch, Parte 3 de 7 Somespeciesofchilopods centipedes Figure1. Nevertheless, a few very earlys chemes agricoola be noted to showhowideas changed as new information became available. Manton see Section 3.

In most centipedes the legs increase in length from the anterior to the posterior of the animal to facilitate rapid movement. Originally, the major drawback to the scheme was a lack of supporting evidence, especially from the fossil record.

Their problem then becomes one of determining the relative importance of similarities and differences that exist between organisms and whether apparently identical, sharedcharactersarehomologous synapomorphic oranalogous seeChapter 4,Section3. On the contrary,t here are quite divergent views with respect to the relationships of the various arthropod groups Figure 1. In outlining the pros and cons of these theories it is useful to separate the mono- andd iphyletict heories appostila thep olyphyletict heory and to present them ina historical context showing the graduald evelopment of evidence in support of one view or the other.

Even after this time the fossil record is incomplete mainly because conditions were unsuitable for preserving rather delicate organisms such as myriapodsa ndi nsects.

Notsurprisingly,forthe reasons noted above, these views havebeen widely divergent. It is believed that the diplosegmental condition enables the animal to exert a strong pushing force df ts legs while retaining rigidity of the trunk region.

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

Martins, Damasceno, Awada – Pronto-socorro Pronto-socorro: At about the same time, after the realization that Limulus is an aquatic arachnid, not a crustacean, it was proposed that the aquatic Eurypterida were the ancestors of all terrestrial arachnids. Similar structures entomoogia foundi eentomologia some apterygote insects. In contrast to the centipedes, the diplopods millipedes Figure 1.

The comparative morphology, embryology,p hysiology, biochemistry and, increasingly, molecular biology of living members of a group provide clues about the evolutionary trends that have occurred within that group. 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.

After chitinization of the cuticle and loss of all except one pair of tentacles which formed the antennaethe lobopods gave rise to the Protonychophora.

The distinguishing feature of the almost 10,0 species aposgila the class is the entomoogia of diplosegments, each bearing two pairs of legs, formed by fusion of two originally separate somites. Only rarely have authors attempted to marshall all of the evidence in order to arrive at an overall conclusion. Schemes for the possible relationships of the hexapod groups as envisaged by BoudreauxKristensenand Kukalova-Peck To this can be added ever-increasing evidence from molecular biology, most but not all o f which supports monophyly.

In determining the evolutionary relationships of animals zoologists use evidence from av ariety of sources.

At the base of the legs of symphylans are eversiblev esicles and coxal styli. 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.

This does not mean, however, that the problem has been solved!

Entomology (Gillott, ) – Livro que trata de aspectos gerais da Entomologia

Five groups of six-legged arthropods hexapods are recognized: Collembola haveas ix-segmented abdomen bearing specialized appendages see Chapter 5, Section 2total cleavagei nt he egg, a long composite tibiotarsal? Schemes for the possible monophyletico rigino f the arthropods as proposedb y SnodgrassSharovand Boudreaux 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, andf urther, the ancestrali nsect leg included 1 segments Kukalova-Peck,andi nE dgecombe, Trilobites, crustaceans, and eurypterids were abundant at this time.

As their taxonomic status is controversial,t he Protura, Collembola, and Diplura have been included with the thysanurans in Chapter 5 where details of their biology are presented. Indeed,t he extensive cladistic analysiso f Bitsch and Bitsch rejects the monophyly of the Ellipura. As Mantonp. Within the last 50 years, much evidence has been accumulated in the areas of functional morphology and comparative embryology but especially inp aleontology and molecular biology, whichh as been broughtt o bear on the matter of arthropod phylogeny.
