To this can be added ever-increasing evidence from molecular biology, most but not all o f which supports monophyly. Even then, there may be no agreement! The position of the Diplura is questionable, and the group is probably not monophyletic Bitsch and Bitsch, This means that the apterygote insects must have evolved from winged forms, which is contrary to all available evidence.

Manton see Section 3. On the contrary,t here are quite divergent views with respect to the relationships of the various arthropod groups Figure 1.

As their taxonomic status is aposhila he Protura, Collembola, and Diplura have been included with the thysanurans in Chapter 5 where details of their biology are presented.
Entomology (Gillott, 2005)
The symphylan and insectan heads have an identical number of segments and, according to some zoologists, the mouthparts of symphylans are insectan inc haracter. However, Bitsch and Bitsch argue stronglyt hat most of these similarities ed due to convergence; that is, the Entognatha is not a monophyletic group.
The Protarthropoda gaverise to the Protrilobita from which thet rilobite—chelicerate line developed and the Protomandibulata Crustacea and Protomyriapoda.
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. A characteristic feature are the large tergal plates on the trunk, which overlap adjacent segments Figure 1.

The associated fauna suggested that this creature was from a marine or amphibious habitat.

It is believed that these large structures prevent lateral undulations during locomotion. Schemes for the possible relationships of the hexapod groups as envisaged by BoudreauxKristensenand Kukalova-Peck 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.

Even after this time the fossil record agricolw incomplete mainly because conditions were unsuitable for preserving rather delicate organisms such as myriapodsa ndi nsects. Originally, the major drawback to the scheme was a lack of supporting evidence, especially from the fossil record.
In most centipedes the legs increase in length from the anterior to the posterior of the animal to facilitate rapid movement. Aspectos Ambientais Aspectos Ambientais.
From the protomyriapods apostioa the myriapods and hexapods. Five groups of six-legged arthropods hexapods are recognized: 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. In determining the apsotila relationships of animals zoologists use evidence from av ariety of sources.
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.
This should not be interpreted to mean that there is agreement among the monophyleticists as to a general scheme for arthropod evolution. Therefore, arthropod phylogeneticists have had to rely almost entirely on comparative studies.
