Abstract: | Background The issue of whether coelomates form a single clade, the Coelomata, or whether all animals that moult an exoskeleton (such
as the coelomate arthropods and the pseudocoelomate nematodes) form a distinct clade, the Ecdysozoa, is the most puzzling
issue in animal systematics and a major open-ended subject in evolutionary biology. Previous single-gene and genome-scale
analyses designed to resolve the issue have produced contradictory results. Here we present the first genome-scale phylogenetic
evidence that strongly supports the Ecdysozoa hypothesis. |
