Employing rich detail, international experts across several fields address the evolution and phylogenetic relationships of the Arthropoda. They offer innovative ideas to reevaluate the phylogeny of major groups, discuss the evolution of arthropod eyes in a phylogenetic context, present a comprehensive overview of appendage loss and regeneration, and address recent molecular phylogenetic data, including nuclear and mitochondrial DNA sequences. While it is still crustaceo-centric, the focus of this volume has been extended to include other arthropods. This wider focus offers challenging opportunities to evaluate higher-level relationships within the Arthropoda from a carcinologic perspective.
