Morphology, molecules and taxonomy: extreme incongruence in pleurocerids (Gas…

Mitochondrial markers have been among the most utilized loci for phylogenetic inference, especially for understudied invertebrate groups for which we yet lack genomic resources. Mitochondrial genes generally evolve faster than nuclear genes and have smaller effective population sizes (Funk & Omland 2003), which has contributed to their popularity in species-level studies. Although the evolut…
