Peripatus was placedi nt he Annelida, its several arthropodf eatures presumed to bet he resulto f convergence. 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.

Note also the differing relationships of the Annelida, Onychophora, and Arthropoda. Within the last 50 years, much evidence has been accumulated in the areas of functional morphology and comparative embryology but especially inp aleontology and molecular biology, whichh as been broughtt o bear on the matter of arthropod phylogeny.
In determining the evolutionary relationships of animals zoologists use evidence from av ariety of sources. The associated fauna suggested that this creature was from a marine or amphibious habitat.
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.
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. The Protarthropoda gaverise to the Protrilobita from which thet rilobite—chelicerate line developed and the Protomandibulata Crustacea and Protomyriapoda.
This proposal may be somewhat close to reality as there isn ow fossil evidence that early insects had appendages with side branches, comparablet ot hose crustaceans, andf urther, the ancestrali nsect leg included 1 segments Kukalova-Peck,andi nE dgecombe, In most centipedes the legs increase in length from the anterior to the posterior of the animal to facilitate rapid movement.
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. 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.
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. Evolution is a process ofd ivergence, and yet, paradoxically, organisms may evolve toward as imilar way of life andh ence develop similar structures. 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.
On the contrary,t here are quite divergent views with respect to the relationships of the various arthropod groups Figure 1. 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 means that the apterygote insects must have evolved from winged forms, which is contrary to all available evidence.
Indeed,t he extensive cladistic analysiso f Bitsch and Bitsch rejects the monophyly of the Ellipura.

From the protomyriapods arose the myriapods and hexapods. Even then, there may be no agreement! At the base of the legs of symphylans are eversiblev esicles and coxal styli. It is believed that these large structures prevent lateral undulations during locomotion.

Therefore, arthropod phylogeneticists have had to rely apostils entirely on comparative studies. Aspectos Ambientais Aspectos Ambientais.
