Phylogenetic, morphological, and developmental data concerning the Arthropoda are reviewed and discussed with the aim of reconstructing the ancestral body plan of the mandibulate arthropods (Myriapoda, Hexapoda, Crustacea). Comparative morphology as well as embryology of malacostracans and hexapods (cell‐lineages, patterns of mitotic domains, patterns of en‐stripe formation, expression zones of pair‐rule, homeotic, and gap‐like genes) suggest that (a) the basic boundary subdividing the… 

Limb ontogeny and trunk segmentation in Nebalia species (Crustacea, Malacostraca, Leptostraca)

The presence of a row of ventral, sternitic, triangular processes between the bases of the thoracopods, as they are found in certain stages of a species of Nebalia, is suggested as a possible ground pattern for the Malacostraca.

Hox genes and the evolution of the arthropod body plan 1

In this review, the expression and functional data regarding the 10 arthropod Hox genes are summarized and mechanisms of developmental evolutionary change thought to be important for the emergence of novel morphological features within the arthropods are discussed.

The Tetraconata concept: hexapod-crustacean relationships and the phylogeny of Crustacea

Arguments for homology of the mandible throughout mandibulate arthropods and for a monophyletic Mandibulata will be presented, as well as arguments supporting the taxon Tetraconata (i.e. Crustacea + Hexapoda).

Filling the gap between identified neuroblasts and neurons in crustaceans adds new support for Tetraconata

The data strongly suggest homology of NBs and their lineages, providing further evidence for a close insect–crustacean relationship.

Phylogenetic relationships of basal hexapods among the mandibulate arthropods: a cladistic analysis based on comparative morphological characters

The results support the monophyly of the Mandibulata, Crustacea, Atelocerata (Tracheata) and Hexapoda, but the assemblage of Myriapoda appears poorly supported.

Neurogenesis in myriapods and chelicerates and its importance for understanding arthropod relationships.

It is shown here that neural precursor identity seems to be achieved in a similar way to chelicerates and myriapods, providing the first morphological support for the Myriochelata group.

Mushroom body evolution demonstrates homology and divergence across Pancrustacea

It is demonstrated that mushroom bodies typify lineages that arose before Reptantia and exist in ReptantIA thereby indicating that the mushroom body, not the hemiellipsoid body, provides the ground pattern for both crustaceans and hexapods.

Neurogenesis in the chilopod Lithobius forficatus suggests more similarities to chelicerates than to insects

Chelicerates and myriapods share the developmental mechanism for neurogenesis, either because they are true sister groups, or because this reflects the ancestral state of neurogen Genesis in arthropods.

Axogenesis in the central and peripheral nervous system of the amphipod crustacean Orchestia cavimana.

The formation of the major axon pathways in the embryonic central and peripheral nervous systems of the amphipod crustacean Orchestia cavimana Heller, 1865 are described by means of antibody staining against acetylated alpha-tubulin and provide a basis for future studies of neurogenesis on a deeper cellular and molecular level.



Hox genes and the diversification of insect and crustacean body plans

It is proposed that the branchiopod thorax may be homologous to the entire pregenital (thoracic and abdominal) region of the insect trunk, and a multistep process for the diversification of these Hox gene functions is suggested.

Comparisons of Hox gene deployment between insects and a branchiopod crustacean suggest a novel model for the derivation of the insect body plan.

The Evolution of the Insect Head: the Endless Dispute

The proposal is made that the ancestor of the insect was annelid-like, that the prostomium became the acron and that the six originally postoral segments joined the acron to form the head tagma.

Ribosomal DNA phylogeny of the major extant arthropod classes and the evolution of myriapods

Using nuclear ribosomal gene sequences for constructing a molecular phylogeny, this work provides strong evidence that the crustaceans and not the myriapods should be considered to be the sister group of the insects.

The evolving role of Hox genes in arthropods.

The diversity of Antennapedia-class homeotic genes present in modern insects had already arisen before the divergence of insects and crustaceans, probably during the Cambrian, suggestisons between Hox genes in different arthropods.

Pentastomid parasites from the Lower Palaeozoic of Sweden

The fossils clearly document the marine origin of the Pentastomida, and that their specific morphology and parasitic life style were already established in the late Cambrian at a high degree of diversification, long before the terrestrialisation of their present final hosts, the tetrapods.

Insect-Crustacean Relationships: Insights from Comparative Developmental and Molecular Studies

The available morphological evidence is examined and it is suggested that insects could emerge from this crustacean-like ancestor independently from myriapods, and after the major crustACEan radiations.

Owen revisited: a reappraisal of morphology in evolutionary biology

A new analysis within the framework of developmental genetics provides both raw data and theoretical support to the “old” morphology and suggests a new, more predictive, approach to the concept of

Serially homologous engrailed stripes are generated via different cell lineages in the germ band of amphipod crustaceans (Malacostraca, Peracarida).

The comparison of the development of the early engrailed stripes in different insects and crustaceans reveals some similarities which show that earlyEngrailed expression is not necessarily clonally inherited, and suggests that initial engrailing expression is independent of a certain cell lineage or division pattern.
