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 …

Pioneering molecular work on chelicerate visual system development in the horseshoe crab
Limulus polyphemus surprised with the possibility that this process may not depend on the …

Single cell RNA sequencing (scRNA-seq) has become a core tool for researchers to
understand biology. As scRNA-seq has become more ubiquitous, many applications …

Vestigial organs provide a link between ancient and modern traits and therefore have great
potential to resolve the phylogeny of contentious fossils that bear features not seen in extant …

The proliferation of genomic resources for Chelicerata in the past 10 years has revealed that
the evolution of chelicerate genomes is more dynamic than previously thought, with multiple …

Although spiders are one of the most diverse groups of arthropods, the genetic architecture
of their evolutionary adaptations is largely unknown. Specifically, ancient genome-wide …

Background The common house spider Parasteatoda tepidariorum represents an emerging
new model organism of arthropod evolutionary and developmental (EvoDevo) studies …

The formation of extraembryonic membranes (EEMs) contributes to the proper development
of many animals. In arthropods, the formation and function of EEMs have been studied best …

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 …

The chelicerate body plan is distinguished from other arthropod groups by its division of
segments into two tagmata: the anterior prosoma (cephalothorax) and the posterior …
