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

Neofunctionalization of duplicated gene copies is thought to be an important process
underlying the origin of evolutionary novelty and provides an elegant mechanism for the …

Most chelicerates operate the world with two kinds of visual organs, the median and lateral
eyes of the arthropod ground plan. In harvestmen (Opiliones), however, members of the …

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

Background Spiders evolved different types of eyes, a pair of primary eyes that are usually
forward pointing, and three pairs of secondary eyes that are typically situated more posterior …

Many invertebrates possess more than two pairs of eyes—but does eye redundancy aid in
ecological diversification? A new study finds varied size adaptation of different eye pairs in …

Background: Many animal lineages utilize Pax6 transcription factors during eye
development. Within Arthropoda, evidence suggests that Pax6 genes are necessary for the …
