Arthropods are the most diverse group of animals and have been so since the Cambrian
radiation. They belong to the protostome clade Ecdysozoa, with Onychophora (velvet …

Phylogenomics reconstructs an arthropod tree in which a monophyletic A rthropoda splits
into P ycnogonida+ E uchelicerata and M yriapoda+ P ancrustacea. The same chelicerate …

Summary The superphylum Panarthropoda (Arthropoda, Onychophora, and Tardigrada)
exhibits a remarkable diversity of segment morphologies, enabling these animals to occupy …

For more than a century, the origin and evolution of the arthropod head and brain have
eluded a unifying rationale reconciling divergent morphologies and phylogenetic …

The panarthropod head represents a complex body region that has evolved through the
integration and functional specialization of the anterior appendage-bearing segments …

The euarthropod head is a highly versatile and functionally specialized body region
composed of multiple appendage-bearing segments and whose complex evolution has …

A widely (although not universally) accepted model of arthropod head evolution postulates
that the labrum, a structure seen in almost all living euarthropods, evolved from an anterior …

The organization of the head provides critical data for resolving the phylogenetic
relationships and evolutionary history of extinct and extant euarthropods,. The early …

We describe Collinsium ciliosum from the early Cambrian Xiaoshiba Lagerstätte in South
China, an armored lobopodian with a remarkable degree of limb differentiation including a …

Gene expression has been employed for homologizing body regions across bilateria. The
molecular comparison of vertebrate and fly brains has led to a number of disputed homology …
