Advances In Molecular Phylogeny Of Crustaceans In The Light Of Phylogenomic Data

Phylogenetic analyses based on large molecular data sets are reviewed, including results of the "Deep Metazoan Phylogeny" project. The phylogeny of Crustacea is still little understood and tree topologies based on molecular data are not congruent with many other morphological data especially for deeper nodes. Earlier analyses using DNA data were not mutually consistent, but more recent analyses have achieved some stability due to better taxon sampling, longer alignments and more sophisticated data selection and modeling. Orthology prediction and gene selection strongly influence results. The current phylogenies place Remipedia and not Branchiopoda close to insects, usually Malacostraca appear closer to Cirripedia and Copepoda, monophyletic Maxillopoda were never recovered.
