Phylogenomics underpins a stable and mostly well-resolved hypothesis for the
interrelationships of extant arthropods. Exceptionally preserved fossils are integrated into …

One of the most widespread and diverse animal groups of the Cambrian Explosion is a
clade of stem lineage arthropods known as Radiodonta, which lived exclusively in the early …

In addition to being among the most iconic and bizarre-looking Cambrian animals,
radiodonts are a group that offers key insight into the acquisition of the arthropod body plan …

Resolving the early evolution of euarthropods is one of the most challenging problems in
metazoan evolution,. Exceptionally preserved fossils from the Cambrian period have …

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 …

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 anterior-most unit of the crown-group arthropod body plan includes three segments, the
pre-gnathal segments, that contain three neuromeres that together comprise the brain …

A crucial step in the evolution of Euarthropoda (chelicerates, myriapods, pancrustaceans)
was the transition between fossil groups that possessed frontal appendages innervated by …

Summary The early Cambrian Kylinxia zhangi occupies a pivotal position in arthropod
evolution, branching from the euarthropod stem lineage between radiodonts (Anomalocaris …
