Abstract
Aplacophorans and polyplacophorans (chitons) have long been argued to be basal molluscs. We present a molecular phylogeny including the aplacophorans Neomeniomorpha (Solenogastres) and Chaetodermomorpha (Caudofoveata). Our analysis recovered instead the clade Aculifera (Aplacophora + Polyplacophora). A relaxed Bayesian molecular clock estimates an Early Ordovician appearance of the aculiferan crown group. This is consistent with the presence of chiton-like molluscs (paleoloricates) with seven or eight dorsal shell plates, interpreted to be ancestral to both chitons and aplacophorans, in the Late Cambrian (~501-490 million years ago). Molecular, embryological and palaeontological data indicate that the aplacophorans evolved from chiton-like ancestors. The recovery of cephalopods as a sistergroup to aculiferans suggests that the plesiomorphic condition in molluscs might be a morphology similar to monoplacophoran limpets.
