Most species on Earth are insects and thus, understanding their evolutionary relationships is
key to understanding the evolution of life. Insect relationships are increasingly well …

Arthropods are the most diverse group of animals and have been so since the Cambrian
radiation. They belong to the protostome clade Ecdysozoa, with Onychophora (velvet …

Meiobenthology is the science of the tiny animals that live in huge numbers in all aquatic
sediments. This fully revised and enlarged second edition emphasizes new discoveries and …

The relationships of major arthropod clades have long been contentious, but refinements in
molecular phylogenetics underpin an emerging consensus. Nevertheless, molecular …

Gastropods are a highly diverse clade of molluscs that includes many familiar animals, such
as limpets, snails, slugs and sea slugs. It is one of the most abundant groups of animals in …

Understanding the head is one of the great challenges in the fields of comparative anatomy,
developmental biology, and palaeontology of arthropods. Numerous conflicting views and …

Twenty years after its proposal, the monophyly of molting protostomes—Ecdysozoa—is a
well-corroborated hypothesis, but the interrelationships of its major subclades are more …

Understanding the evolution of Tetraconata or Pancrustacea—the clade that includes
crustaceans and insects—requires a well-resolved hypothesis regarding the relationships …

We present the largest morphological character set ever compiled for Holometabola. This
was made possible through an optimized acquisition of data. Based on our analyses and …

This work expands on a study from 2004 by Mallatt, Garey, and Shultz [Mallatt, JM, Garey,
JR, Shultz, JW, 2004. Ecdysozoan phylogeny and Bayesian inference: first use of nearly …
