The direction of evolution within the Polychaeta
The phylogenetic systematics of the polychaetes, i.e. the non-clitellate annelids, depend on which characters are regarded as belonging to the bauplan of the annelid stem species. The mainExpand

The Evolution of Annelids Reveals Two Adaptive Routes to the Interstitial Realm
Many animals permanently inhabit the marine interstitium, the space between sand grains [1, 2]. Different evolutionary scenarios may explain the existence of interstitial animals [3, 4]. TheseExpand

Are Echiura derived from a segmented ancestor? Immunohistochemical analysis of the nervous system in developmental stages of Bonellia viridis
Despite several unquestionably homologous characters with Annelida, the Echiura have generally been considered to form a distinct taxon due to apparent lack of segmentation: neither in the bodyExpand

Progenesis in Eunicida ("Polychaeta," Annelida)--separate evolutionary events? Evidence from molecular data.
The Eunicida are a well-defined annelid taxon currently comprising Dorvilleidae, Lumbrineridae, Eunicidae, Onuphidae, and Hartmanniellidae. Especially the Dorvilleidae include several species ofExpand

Two new terrestrial Enchytraeus species (Oligochaeta, Annelida)
Enchytraeus crypticus n.sp. and Enchytraeus doerjesi n.sp. were discovered in laboratory cultures of terrestrial enchytraeids in the course of a project evaluating various non-light-microscopicalExpand

Morphological reinvestigation and phylogenetic relationship of Acanthobdella peledina (Annelida, Clitellata)
SummaryIn recently collected specimens of Acanthobdella peledina the nervous system, the genital organs and the coelomic organisation were reinvestigated after complete serial sections. TheseExpand

Progenesis as a principle in meiofauna evolution
The interstitial meiofaunal taxa may have evolved in very different ways, which are shortly discussed and schematically represented. Several taxa reveal the possibility of an evolutionary pathway byExpand

CLSM analysis of development and structure of the central nervous system of Enchytraeus crypticus (”Oligochaeta”, Enchytraeidae)
Abstract The phylogenetic position of the Clitellata within the Annelida is still in debate. It is unresolved whether they are a basal group, resembling the stem species of the Annelida, or a highlyExpand
