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

The basal phylogeny of Chelicerata is one of the opaquest parts of the animal Tree of Life,
defying resolution despite application of thousands of loci and millions of sites. At the …

Deciphering the evolutionary relationships of Chelicerata (arachnids, horseshoe crabs, and
allied taxa) has proven notoriously difficult, due to their ancient rapid radiation and the …

Gene duplication generates new genetic material that can contribute to the evolution of gene
regulatory networks and phenotypes. Duplicated genes can undergo subfunctionalization to …

Spiders are a diverse order of chelicerates that diverged from other arthropods over 500
million years ago. Research on spider embryogenesis, particularly studies using the …

Salmonid fishes have emerged as a tractable model to study whole‐genome duplications
(WGDs) as this group has undergone four rounds of WGDs. While most of the salmonid …

Within the arachnids, chromosome-level genome assemblies have greatly accelerated the
understanding of gene family evolution and developmental genomics in key groups, such as …

This perspective identifies the grand challenges in arachnid science: 1. Grasp the arachnid
species diversity. There is a need to accelerate taxonomic research to obtain a sense of …

Spiders (Araneae) have a diverse spectrum of morphologies, behaviors, and physiologies.
Attempts to understand the genomic-basis of this diversity are often hindered by their large …

Background The resurgence of interest in the comparative developmental study of
chelicerates has led to important insights, such as the discovery of a genome duplication …
