Significance Most arthropod diversity is now found on land, with hexapods (insects), arachnids, and myriapods being major terrestrial radiations. Molecular dating consistently predicts that these groups have earlier evolutionary origins than are recorded by fossils. A reason for this difference between molecular- and fossil-based age estimates is that few candidates for marine or freshwater stem groups of these terrestrial lineages have been identified.

A new Devonian euthycarcinoid reveals the use of different respiratory strategies during the marine-to-terrestrial transition in the myriapod lineage
New data provide additional support for amphibious lifestyle in euthycarcinoids and show that different respiratory strategies were used during the marine-to-terrestrial transition in the myriapod lineage.

The rise of arthropods is a decisive event in the history of life. Likely the first animals to have established themselves on land and in the air, arthropods have pervaded nearly all ecosystems and
Macroevolutionary patterns of body plan canalization in euarthropods
Overall ordination patterns between the main morphogroups are consistent with another, independently coded, extant-only dataset providing molecular and morphological rates of evolution, which would support the view that the swiftness of the Cambrian explosion was mostly associated with the buildup of genetic regulatory networks.
Fuxianhuiids are mandibulates and share affinities with total-group Myriapoda
In spite of their unrivalled ecological success, the origins of terrestrial mandibulates have long remained virtually unknown. In recent years, claims have been made based on phylogenetic results
Taxonomic sampling and rare genomic changes overcome long-branch attraction in the phylogenetic placement of pseudoscorpions
The recent discovery of an ancient genome duplication in the common ancestor of Arachnopulmonata is leveraged as a litmus test for competing hypotheses of pseudoscorpion relationships and shows that concatenated supermatrices and coalescent-based summary species tree approaches support a sister group relationship of Pseudoscorpions and scorpions, when more of the basally branching taxa are sampled.

A molecular palaeobiological exploration of arthropod terrestrialization
A molecular palaeobiological approach is implemented, merging molecular and fossil evidence, to elucidate the deepest history of the terrestrial arthropods and showed that a marine route to the colonization of land is the most likely scenario.
Cambrian origins and affinities of an enigmatic fossil group of arthropods
A euthycarcinoid from marine strata in Argentina dating from the latest Cambrian period is described, extending the group's record back as much as 50 million years and demonstrating that morphological details were conserved in the transition to fresh water.
Arthropod fossil data increase congruence of morphological and molecular phylogenies.
Enhanced congruence is shown between molecular and morphological phylogenies based on 753 morphological characters for 309 fossil and Recent panarthropods, which resolve hexapods within Crustacea, with remipedes as their closest extant relatives, and show that the traditionally close relationship between myriapods and hexapod is an artefact of convergent character acquisition during terrestrialisation.
A euthycarcinoid arthropod from the Silurian of Western Australia
The discovery of a euthycarcinoid about 120 million years older than the previous oldest record, and predating the oldest known hexapod, provides strong support for the view that the hexapods may have evolved from the EuthycARCinoidea.
Phylogenomics illuminates the backbone of the Myriapoda Tree of Life and reconciles morphological and molecular phylogenies
The first transcriptomic data including a pauropod and both families of symphylans is presented, allowing myriapod interrelationships to be inferred from phylogenomic data from representatives of all main lineages.
Fossils from South China redefine the ancestral euarthropod body plan
Sklerolibyon and other jianfengiids expand the disparity of megacheirans and suggest that the common euarthropod ancestor possessed a remarkable phenotypic variability associated with the externalized cephalon, as well as endopods that were already heptopodomerous, which differs from previous hypotheses and observations.
Burgess Shale fossils illustrate the origin of the mandibulate body plan
The presence of crustaceomorph traits in the Cambrian larvae of various clades basal to Mandibulata is reinterpreted as evidence for the existence of distinct ontogenetic niches among stem arthropods and Hymenocarines now illustrate that the subdivision of the basipod and the presence of proximal endites are likely to have been ancestral conditions critical for the evolution of coxal and pre-coxal features in mandibulates.
Phylogenomics resolves the timing and pattern of insect evolution
The phylogeny of all major insect lineages reveals how and when insects diversified and provides a comprehensive reliable scaffold for future comparative analyses of evolutionary innovations among insects.
