Morphology has traditionally played a pivotal role in animal phylogeny since the first
evolutionary biologists began to decipher the animal tree of life. In recent times, however …

The molecular clock has played an important role in biological research, both as a
description of the evolutionary process and as a tool for inferring evolutionary timescales …

Chelicerata represents one of the oldest groups of arthropods, with a fossil record extending
to the Cambrian, and is sister group to the remaining extant arthropods, the mandibulates …

Background RNA-seq has shown huge potential for phylogenomic inferences in non-model
organisms. However, error, incompleteness, and redundant assembled transcripts for each …

Eusocial behavior has arisen in few animal groups, most notably in the aculeate
Hymenoptera, a clade comprising ants, bees, and stinging wasps [1–4]. Phylogeny is crucial …

Arachnida is an ancient, diverse and ecologically important animal group that contains a
number of species of interest for medical, agricultural and engineering applications. Despite …

Sequence capture of ultraconserved elements (UCEs) has transformed molecular
systematics across many taxa, with arachnids being no exception. The probe set available …

Pseudoscorpiones, with nearly 3700 described species, are an ancient and globally
distributed group of arachnids with a fossil record dating back to the Middle Devonian …

Scorpions represent an iconic lineage of arthropods, historically renowned for their unique
bauplan, ancient fossil record and venom potency. Yet, higher level relationships of …

Introduction Traditionally, genomic or transcriptomic data have been restricted to a few
model or emerging model organisms, and to a handful of species of medical and/or …
