Abstract: | Nucleotide and inferred amino acid sequences from two nuclear protein-encoding genes, elongation factor-aα and RNA polymerase II, were obtained from 34 myriapods and 14 other arthropods to determine phylogenetic relationships among and within the myriapod classes. Phylogenetic analyses using maximum parsimony and maximum likelihood methods recovered all three represented myriapod classes (Chilopoda, Diplopoda, Symphyla) and all multiply sampled chilopod and diplopod orders, often with high node support. In contrast, relationships between classes and between orders were recovered less consistently and node support was typically lower. The temporal structure of phylogenetic diversification in Myriapoda may explain this apparent pattern of the phylogenetic recovery. |
