Schemes for the possible relationships of the hexapod groups as envisaged by BoudreauxKristensenand Kukalova-Peck Aspectos do Neoconstitucionalismo Aspectos do Neoconstitucionalismo Material cedido pelo professor Jaciratan.

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. Although forming only a very small class of arthropods speciestheS ymphyla have stimulated speciali nterest among entomologists because of the several features they share with insects, leading to the suggestion that the two groups may have had a common ancestry.

Wpostila their taxonomic status is controversial,t he Protura, Collembola, and Diplura have been included with the thysanurans in Chapter 5 where details of entomoolgia biology are presented. 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.

To this can be added ever-increasing evidence from molecular biology, most but not all o f which supports monophyly. Evolution is a process ofd ivergence, and yet, paradoxically, organisms may evolve toward as imilar way of life andh ence develop similar structures.

On the contrary,t here are quite divergent views with respect to the relationships of the various arthropod aggricola Figure 1. Despite these similarities, theC ollembolaa nd Protura are quite distinct bothf rom each other andf rom other hexapods. The monophyleticists, on the other hand, believe that the mandibles of crustaceans, myriapods, and hexapods are homologous.

In contrast to the centipedes, the diplopods millipedes Figure 1. Within the last 50 years, much evidence has been accumulated in the areas of functional morphology and comparative embryology but especially inp aleontology agrciola molecular biology, whichh as been broughtt o bear on the matter of arthropod phylogeny.

The earliest known apkstila centipedes, from the Upper Silurian, are remarkablys imilar to some extant species, suggesting that the group may be considerably more ancient. A characteristic feature are the large tergal plates on the trunk, which overlap adjacent segments Figure 1. The Protarthropoda gaverise to the Protrilobita from which thet rilobite—chelicerate line developed and the Protomandibulata Crustacea and Protomyriapoda.

In most centipedes the legs increase in length from the anterior to the posterior of the animal to facilitate ebtomologia movement.

Unfortunately, in the case of arthropodst he early fossil recordi s poor.

Itw ill be readily apparent thatav ariety of schemes have been devised to show the possible relationships of the hexapod groups Figure 1. It is, however, only the fossil record that can provide the direct evidence for such processes. Notsurprisingly,forthe reasons noted above, these views havebeen widely divergent. It is believed that these large structures prevent lateral undulations during entomoogia. From the protomyriapods arose the myriapods and hexapods.

Such organisms livedi ns hallow water near thes hore or int he littoral zone. Note also the differing relationships of the Annelida, Onychophora, and Arthropoda.

Some authors have suggested thatthearthropodsaremonophyletic,thatis,haveacommonancestor;othershaveproposed thatthegroupisdiphyletic twomajorsubgroupsevolvedfromacommonancestor ,andyet others believe that each apostia subgroup evolved independently of the others a polyphyletic 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. Trilobites, crustaceans, and eurypterids were abundant at this time.

As Mantonp. This proposal may be somewhat close to agricolq as there isn ow fossil evidence that early insects had appendages with side branches, comparablet ot hose crustaceans, andf urther, the ancestrali nsect enttomologia included 1 segments Kukalova-Peck,andi nE dgecombe, Pauropoda species are minute arthropods 0. However, Bitsch and Bitsch argue stronglyt hat most of these similarities are due to convergence; that is, the Entognatha is not a monophyletic group.

Even then, there may be no apostlia The position of the Diplura is questionable, and the group is probably not monophyletic Bitsch and Bitsch, 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.

Their problem then becomes one of determining the relative importance of similarities apostia differences that exist between organisms and whether apparently identical, sharedcharactersarehomologous synapomorphic oranalogous seeChapter 4,Section3.

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

Apostila Entomologia resumida

In outlining the pros and cons of these theories it apostilaa 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. Therefore, arthropod phylogeneticists have had to rely almost entirely on comparative studies.

Similar structures are foundi n some apterygote insects. 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.

The comparative morphology, embryology,p hysiology, biochemistry and, increasingly, molecular biology of living members abricola a group provide clues about the evolutionary trends that have occurred within that group. Manton see Section 3. In a nutshell, proponents of the monophyletic theory simply point to the abundance of features common to arthropods Section 2 and argue that so many similarities could.

At about the same time, after the realization that Limulus is an aquatic arachnid, not a agrickla, it was proposed that the aquatic Eurypterida were the ancestors of all terrestrial arachnids.
