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. Some authors have suggested thatthearthropodsaremonophyletic,thatis,haveacommonancestor;othershaveproposed thatthegroupisdiphyletic twomajorsubgroupsevolvedfromacommonancestor ,andyet others entomologiaa that each major subgroup evolved independently of the others a polyphyletic origin.
The monophyleticists, on the other hand, believe that the mandibles of crustaceans, myriapods, and hexapods are homologous.
Space does not permit a detailed account of the early history of monophyletic proposals and readers interested in this should consult Tiegs and Manton This does not mean, however, that the problem has been solved! Even after this time the fossil record is incomplete mainly because conditions were unsuitable for preserving rather delicate organisms such as myriapodsa ndi nsects.
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.

Originally, the major drawback to the scheme was a lack of supporting evidence, entomolovia from the fossil record. Despite these similarities, theC ollembolaa nd Protura are quite distinct bothf rom each other andf rom other hexapods. The associated fauna suggested that this creature was from a marine or amphibious habitat.

Entomology Gillott, Bruno row Enviado por: Itw ill be readily apparent thatav ariety of schemes have been devised to show the possible apoxtila of the hexapod groups Figure 1. As Mantonp. Schemes for the possible relationships of the hexapod groups as envisaged by BoudreauxKristensenand Kukalova-Peck On the contrary,t here are quite divergent views with respect to the relationships of the various arthropod groups Figure 1.
The position of the Diplura is questionable, and the group is probably not monophyletic Bitsch and Bitsch, 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 symphylan and insectan heads have an identical number of segments and, according to some zoologists, the mouthparts of symphylans are insectan inc haracter. From the protomyriapods arose the agricila and hexapods.

This should not be interpreted to mean that there is agreement among the monophyleticists apostia to a general scheme for arthropod evolution. Peripatus was placedi nt he Annelida, its several arthropodf eatures presumed to bet he resulto f convergence. To this can be added ever-increasing evidence from molecular biology, most but not all o f which supports monophyly.
Apostila Entomologia resumida
Similar structures are foundi entomoolgia some apterygote insects. 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. Even then, there may be no agreement! Evolution is a process entomolofia ivergence, and yet, paradoxically, organisms may evolve toward as imilar way of life andh ence develop similar structures. This means that the apterygote insects must have evolved from winged forms, which is contrary to all available evidence.
Entomology (Gillott, 2005)
Apostlla see Section 3. Therefore, arthropod phylogeneticists have had to rely almost entirely on comparative studies. Note also the differing relationships of the Annelida, Onychophora, and Arthropoda. The Protarthropoda gaverise to the Protrilobita from which thet rilobite—chelicerate line developed and the Protomandibulata Crustacea and Protomyriapoda.

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. In outlining the pros and cons of these theories it entomolohia useful to separate the entomologi andd iphyletict heories from thep olyphyletict heory and to present them ina historical context showing the graduald evelopment of evidence in support of one view or the other.
At the base of the legs of symphylans are eversiblev esicles and coxal styli. 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.
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. Indeed,t he extensive cladistic analysiso f Agricols and Bitsch rejects the monophyly of the Ellipura.
