DataSheet_2_New perspectives on the evolutionary history of xiphosuran development through comparison with other fossil euchelicerates.docx

, 2023
IntroductionEuchelicerata is a diverse group encompassing Xiphosura, Chasmataspidida, Eurypterida, and Arachnida. Xiphosura represents an extant group with a rich fossil record dating back to the Ordovician period.

Allometric Changes Across Horseshoe Crab Moults Evidence Developmentally Controlled Ecological Shifts and Possible Exoskeletal Modularity

Evolution &Development, Volume 27, Issue 3, September 2025.
This study explores allometric patterns in Limulus polyphemus, highlighting non‐isometric growth in prosoma across moults. These reflect adaptations related to changes in borrowing, offering insights into the evolutionary success of horseshoe crabs and contributing to broader understanding of xiphosuran development.

Evolutionary Conservation and Diversification of Five Pax6 Homologs in the Horseshoe Crab Species Cluster

Arthropoda
Horseshoe crabs represent the most ancestral chelicerate lineage characterized by marine ecology and the possession of lateral compound eyes. While considered living fossils, recent studies reported an unusual number of Pax6 genes in the Atlantic ...

The moulting arthropod: a complete genetic toolkit review

Biological Reviews, Volume 99, Issue 6, Page 2338-2375, December 2024.
ABSTRACT Exoskeletons are a defining character of all arthropods that provide physical support for their segmented bodies and appendages as well as protection from the environment and predation. This ubiquitous yet evolutionarily variable feature has been instrumental in facilitating the adoption of a variety of lifestyles and the exploitation of ...

Phylogenomic subsampling: a brief review

Zoologica Scripta, Volume 45, Issue S1, Page 63-74, October 2016., 2016
Phylogenomic subsampling is a method for studying the stability of phylogenetic analyses by taking random or ordered subsamples of loci and comparing phylogenetic analyses of those subsamples. The method is made possible by the large number of loci made available by application of next‐generation sequencing methods to phylogenetic questions.

A plurality of morphological characters need not equate with phylogenetic accuracy: A rare genomic change refutes the placement of Solifugae and Pseudoscorpiones in Haplocnemata

Evolution &Development, Volume 26, Issue 4, July 2024.
Developmental transcriptomic data support an unduplicated genome in a solifuge, disfavoring the traditional grouping of pseudoscorpions and camel spiders as Haplocnemata. Abstract Recent advances in higher‐level invertebrate phylogeny have leveraged shared features of genomic architecture to resolve contentious nodes across the tree of life.
