Evolutionary relationships of a class of crustaceans
For primer on phylogenetic terminology, see Phylogenetic nomenclature.
Phylogeny of Malacostraca is the evolutionary relationships of the largest of the six classes of crustaceans, containing about 40,000 living species, divided among 16 orders. Its members display a great diversity of body forms. Although the class Malacostraca is united by a number of well-defined and documented features, which were recognised a century ago by William Thomas Calman in 1904,[1] the phylogenetic relationship (the evolutionary tree) of the orders which compose this class is unclear due to the vast diversity present in their morphology. Molecular studies have attempted to infer the phylogeny of this clade,[2][3][4] resulting in phylogenies which have a limited amount of morphological support.[5] To resolve a well-supported eumalacostracan phylogeny and obtain a robust tree, it will be necessary to look beyond the most commonly utilized sources of data (nuclear ribosomal and mitochondrial sequences).[6]
