Broad phylogenomic sampling improves resolution of the animal tree of life
Long-held ideas regarding the evolutionary relationships among animals have recently been upended by sometimes controversial hypotheses based largely on insights from molecular data. These newExpand

Assessing the root of bilaterian animals with scalable phylogenomic methods
A clear picture of animal relationships is a prerequisite to understand how the morphological and ecological diversity of animals evolved over time. Among others, the placement of the acoelomorphExpand

Arthropod phylogeny based on eight molecular loci and morphology
The interrelationships of major clades within the Arthropoda remain one of the most contentious issues in systematics, which has traditionally been the domain of morphologists. A growing body of DNAExpand

Histone H3 and U2 snRNA DNA sequences and arthropod molecular evolution
The range of DNA sequences used to study the interrelationships of the major arthropod groups (chelicerates, myriapods, hexapods and crustaceans) is limited. Here we investigate the value of twoExpand

The evolution of arthropod heads: reconciling morphological, developmental and palaeontological evidence
Understanding the head is one of the great challenges in the fields of comparative anatomy, developmental biology, and palaeontology of arthropods. Numerous conflicting views and interpretations areExpand

MicroRNAs and phylogenomics resolve the relationships of Tardigrada and suggest that velvet worms are the sister group of Arthropoda
Morphological data traditionally group Tardigrada (water bears), Onychophora (velvet worms), and Arthropoda (e.g., spiders, insects, and their allies) into a monophyletic group of invertebrates withExpand

Phylogeny and Systematic Position of Opiliones: A Combined Analysis of Chelicerate Relationships Using Morphological and Molecular Data 1
The ordinal level phylogeny of the Arachnida and the suprafamilial level phylogeny of the Opiliones were studied on the basis of a combined analysis of 253 morphological characters, the completeExpand

Arthropod Cladistics: Combined Analysis of Histone H3 and U2 snRNA Sequences and Morphology
Morphological, developmental, ultrastructural, and gene order characters are catalogued for the same set of arthropod terminals as we have scored in a recent study of histone H3 and U2 snRNAExpand

A congruent solution to arthropod phylogeny: phylogenomics, microRNAs and morphology support monophyletic Mandibulata
While a unique origin of the euarthropods is well established, relationships between the four euarthropod classes—chelicerates, myriapods, crustaceans and hexapods—are less clear. Unsolved questionsExpand

Higher-level metazoan relationships: recent progress and remaining questions
Metazoa comprises 35–40 phyla that include some 1.3 million described species. Phylogenetic analyses of metazoan interrelationships have progressed in the past two decades from those based onExpand
