Rare genomic changes have long been sought by phylogeneticists for their potential to resolve obdurate nodes in the tree of life. Recently, patterns of macrosynteny have been proffered as a breakthrou...

They may be famous for their striking blue blood, but horseshoe crabs have an award-winning vision system.   In the 1930s, Haldan Keffer Hartline produced the first single-cell recording of a photorec...

The first high-quality pycnogonid genome provides novel insights in chelicerate evo-devo

Background Chelicerate evolution is contentiously debated, with recent studies challenging traditional phylogenetic hypotheses and scenarios of major evolutionary events, like terrestrialization. Sea ...

Chromosome-level genome assemblies are powerful tools for identifying the presence of rare genomic changes that can overcome phylogenetically intracta…

A major theme in the evolution of Arthropoda is the origin and diversification of jointed appendages. One appealing framework for the evolution of art…

Visual systems provide a key interface between organisms and their surroundings, and have evolved in many forms to perform diverse functions across the animal kingdom. Spiders exhibit a range of visual abilities and ecologies, the diversity of which is ...

Chromosome-level genome assemblies are powerful tools for identifying the presence of rare genomic changes that can overcome phylogenetically intractable proble

Abstract. Within the arachnids, chromosome-level genome assemblies have greatly accelerated the understanding of gene family evolution and developmental ge

Chelicerata constitutes an ancient, biodiverse, and ecologically significant group of Arthropoda. The study of chelicerate evolution has undergone a renaissance in the past decade, resulting in major ...

The sense of smell is a central sensory modality of most terrestrial species. However, our knowledge of olfaction is based on vertebrates and insec...
