New insights into the evolution of Charlie Chaplin worms (Histriobdellidae, Eunicida, Annelida)

This study uses morphological and molecular analyses to clarify the evolutionary placement of Histriobdellidae within Annelida, supporting their sister group relationship with Dorvilleidae.

Convergent evolution of sensory palps in Scalibregmatidae (Annelida)

This study investigates the neural innervation of palp-like structures in Scalibregmatidae, finding they evolved convergently and differ from homologous structures in other annelids.

A genome resource for the marine annelid Platynereis dumerilii

The paper presents genome assemblies for three Platynereis species to support comparative genomic studies and explore their biology.

Breaking the ladder: Evolution of the ventral nerve cord in Annelida

The paper reconstructs the evolution of the annelid ventral nerve cord using phylogenomic and morphological analyses, finding that a subepidermal ladder-like nerve cord is derived, not ancestral.
