Indeed,t he extensive cladistic analysiso f Bitsch and Bitsch rejects the monophyly of the Ellipura.

Peripatus was placedi nt he Annelida, its several arthropodf eatures presumed to bet he resulto f convergence. The position of the Diplura is questionable, and the group is probably not monophyletic Bitsch and Bitsch, Agrifola the protomyriapods arose the myriapods and hexapods. Unfortunately, in the case of arthropodst he early fossil recordi s poor. 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.

Therefore, arthropod phylogeneticists have had to rely almost entirely on comparative studies. On the contrary,t here are quite divergent views with respect to the relationships of the various arthropod groups Figure 1. Schemes for the possible monophyletico rigino f the arthropods as proposedb y SnodgrassSharovand Boudreaux However, Bitsch fntomologia Bitsch argue stronglyt hat most of these similarities are due to convergence; that is, the Entognatha is not a monophyletic group.

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.

Notsurprisingly,forthe reasons noted above, these views havebeen widely divergent. Some authors have suggested thatthearthropodsaremonophyletic,thatis,haveacommonancestor;othershaveproposed thatthegroupisdiphyletic twomajorsubgroupsevolvedfromacommonancestor ,andyet others believe that each major subgroup evolved independently of the others a entmologia origin. The symphylan and insectan heads have an identical number of segments and, according to some zoologists, the mouthparts of symphylans are insectan inc haracter.

Entomology Gillott, Bruno row Enviado por: To this can be added ever-increasing evidence from molecular biology, most but not all o f which supports monophyly.

This proposal may be somewhat close to reality as there isn ow fossil evidence that early rntomologia had appendages with side branches, comparablet ot hose crustaceans, andf urther, the aposttila nsect leg included 1 segments Kukalova-Peck,andi nE dgecombe, Otherpossiblesynapomorphiesoftheentognathansinclude protrusible mandibles, reduced Malpighian tubules, and reduced or absent compound eyes. Pauropoda species are minute arthropods 0.

A distinction must therefore be made between parallel and convergent evolution. In outlining the pros and cons of these theories it is useful to separate the mono- andd iphyletict heories from thep olyphyletict heory and to present them ina historical context showing the graduald evelopment of evidence in agriccola of one view or the other.

Trilobites, crustaceans, and eurypterids were abundant at this time. Five groups of six-legged arthropods hexapods are recognized: Even after this time the fossil record is incomplete mainly because conditions were unsuitable for preserving rather delicate organisms such as myriapodsa ndi nsects.

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

This should not be interpreted to mean that there is agreement among the monophyleticists as to a general scheme for arthropod evolution.

In thiss cheme the hypothetical ancestral group were the lobopods so-calledb ecause of the lobelike outgrowths of the body wall that served as legs.

This means that the apterygote insects must agficola evolved from winged forms, which is contrary to all available evidence. In contrast to the centipedes, the diplopods millipedes Figure 1. In determining the evolutionary relationships of animals zoologists use evidence from av agridola of sources. The Protarthropoda gaverise to the Protrilobita from which thet rilobite—chelicerate line developed and the Protomandibulata Crustacea and Protomyriapoda.

Only rarely have authors attempted to marshall all of the evidence in order to arrive at an overall conclusion. Similar structures are foundi n some apterygote insects. Nevertheless, a few very earlys chemes should be noted to showhowideas changed as new information became available.

A characteristic feature are the large tergal plates on the trunk, which overlap adjacent segments Figure 1. As Mantonp. Originally, the major drawback to the scheme was a lack of supporting evidence, especially from the fossil record.
