Itw ill be readily apparent thatav ariety of schemes have been devised to show the possible relationships of the hexapod groups Figure 1.

From the protomyriapods arose the myriapods and hexapods.
Within the last 50 years, much evidence has been agricloa in the areas of functional morphology and comparative embryology but especially inp aleontology and molecular biology, whichh as been broughtt o bear on agricpla matter of arthropod phylogeny. Tags Gillot Insetos Entomologia.
On the contrary,t here are quite divergent views with respect to the relationships of the various arthropod groups Figure 1. Note also the differing relationships of the Annelida, Onychophora, and Arthropoda.
Apostila Entomologia resumida
Even then, there may be no agreement! However, Bitsch and Bitsch argue stronglyt hat most of these similarities are due to convergence; that is, the Entognatha is not a monophyletic group. Therefore, arthropod phylogeneticists have had to rely almost entirely on comparative studies. 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.
Aspectos Ambientais Aspectos Ambientais. Notsurprisingly,forthe reasons noted above, these views havebeen widely divergent. 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 support of one view or the other.
engomologia It is, however, only the fossil enhomologia that can provide the direct evidence for such processes.
Pauropoda species are minute arthropods 0. 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. 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.
Entomolpgia 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. Such organisms livedi ns hallow water near thes hore or int he littoral zone. A distinction must therefore be made between parallel and convergent evolution.

Space does not permit a detailed account of the early history of monophyletic proposals and readers interested in this should consult Tiegs and Manton 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.
Manton see Section 3. The associated fauna suggested that this creature was from a marine or amphibious habitat. Similar structures are foundi n some apterygote insects.
The Protarthropoda gaverise to the Protrilobita from which thet rilobite—chelicerate line developed and the Protomandibulata Crustacea and Protomyriapoda. This means that the apterygote insects must have evolved from winged forms, which is contrary to all available evidence.

Evolution is a process ofd ivergence, and yet, paradoxically, organisms may evolve toward as imilar way of life andh ence develop similar structures. As Mantonp. After chitinization of the cuticle and loss of all except one pair of tentacles which formed the antennaethe lobopods gave rise to the Protonychophora.
