The relationships among the four arthropod groups (insects, crustaceans, myriapods, chelicerates) have been a point of controversy for many years. According to the traditional view, the myriapods are most closely related to the insects (common taxon "Tracheata" or Antennata), the crustaceans are the closest relatives of the Antennata (common taxon Mandibulata), and the chelicerates are the sister group of the Mandibulata. However, when the characters that have been used to connect the insects and the myriapods were reviewed, the results suggested that they are either suspected of being convergent (i.e., Malpighian tubules, tracheae) or are not significant in a ...
