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]. These scenarios include (1) that the interstitial realm is the ancestral habitat of bilaterians [5, 6], (2) that interstitial taxa evolved from larger ancestors by miniaturization, or (3) progenesis [3]. The first view mirrors the former hypothesis that interstitial annelids, called archiannelids, were at the… Expand

Annelid Diversity: Historical Overview and Future Perspectives
Annelida is a ubiquitous, common and diverse group of organisms, found in terrestrial, fresh waters and marine environments. Despite the large efforts put into resolving the evolutionaryExpand
Current status of annelid phylogeny
TLDR
The new annelids phylogeny highlights the variability and lability of annelid body plans, and many instances of simplifications of body plan as adaptations to new life styles can be found. Expand
Recent progress in reconstructing lophotrochozoan (spiralian) phylogeny
TLDR
New evidence supporting the inclusion of chaetognaths within gnathiferans, the phylogenetic position of Orthonectida and Dicyemida, as well as the general phylogeny of lophotrochozoans is reviewed. Expand
Exceptionally preserved Cambrian loriciferans and the early animal invasion of the meiobenthos
TLDR
An assemblage of microscopic fossil loriciferans from the late Cambrian Deadwood Formation of western Canada is described, indicating the early evolution and subsequent conservation of an obligate, permanently meiobenthic lifestyle. Expand
The role of progenesis in the diversification of the interstitial annelid lineage Psammodrilidae
TLDR
A combined phylogeny of Psammodrilidae is presented including molecular and morphological data of all eight described species as well as four undescribed species to reveal an unexpected diversity and distribution of this small family. Expand
Evolution of mitochondrial gene order in Annelida.
TLDR
It is demonstrated that the supposedly highly conserved mitochondrial gene order suggested for Annelida is restricted to Pleistoannelida, representing the ground pattern of this group and the first mitochondrial genomes in AnnelIDA that encode genes on both strands are reported. Expand
Annelids in Extreme Aquatic Environments: Diversity, Adaptations and Evolution
TLDR
Modifications common to both polychaetes and clitellates include the ability to construct protective cocoons, make cryoprotective substances such as antifreeze and heat shock proteins, develop gills, transform their bodies into a home for symbiotic chemoautotrophic bacteria, metabolize contaminants, and display avoidance behaviors. Expand
A Cambrian crown annelid reconciles phylogenomics and the fossil record
TLDR
Dannychaeta tucolus is a new fossil polychaete (bristle worm) from the early Cambrian Canglangpu formation that belongs to crown annelids, and has characters that provide evidence of ecological and morphological diversity in ancient annelid evolution, thus reconciling the fossil record with molecular phylogenetic analyses. Expand
Broad North Atlantic distribution of a meiobenthic annelid – against all odds
TLDR
Though often neglected and possibly underestimated among marine microscopic species, dormancy may be a highly significant factor for explaining wide distribution patterns and a key to solving this meiofaunal paradox. Expand
Evolution of cave suspension feeding in Protodrilidae (Annelida)
TLDR
The dramatic changes observed in these primarily interstitial lineages compared to their relatives, point to alternative adaptive evolutionary pathways related to ecological fitness contrary to the previously proposed theories focusing on geological or stochastic processes. Expand

Direction of evolution within Annelida and the definition of Pleistoannelida
TLDR
The ancestral annelid is most likely a mixture of sedentary and errant annelids features indicating an evolutionary origin of Annelida as a microphagous surface deposit-feeder crawling upon and through soft-bottom habitats, and the evolution of iterative parapodia as locomotive devices most likely drove the Evolution of segmentation in AnnelIDA. Expand
Phylogeny of Annelida
TLDR
The phylogeny of Annelida was split into two major clades, one clade adapted to an errant mobile life and the other which includes earthworms and leeches, to a more sessile, sedentary one. Expand
Phylogenomic analyses unravel annelid evolution
TLDR
It is shown that phylogenomic analyses of 34 annelid taxa, using 47,953 amino acid positions, recovered a well-supported phylogeny with strong support for major splits and Ancestral character trait reconstructions indicate that these clades show adaptation to either an errant or a sedentary lifestyle.

Illuminating the base of the annelid tree using transcriptomics.
TLDR
This study based on transcriptomic data comprising 68,750-170,497 amino acid sites from 305 to 622 proteins resolves annelid relationships, including Chaetopteridae, Amphinomidae, Sipuncula, Oweniidae, and Magelonidae in the basal part of the tree. Expand
Dinophilidae (Annelida) is most likely not a progenetic Eunicida: evidence from 18S and 28S rDNA.
TLDR
The most convincing evidence for a close relationship between dinophilids and eunicidans is from Akesson’s (1977) experiments demonstrating reciprocal infection with coelomic coccidia of the genus Grellia, parasites that are generally thought to be host-speciWc. Expand
Progenesis as a principle in meiofauna evolution
TLDR
It is emphasized that progenetic evolution is not regressive or degenerate but novel morphological features like derived reproductive organs are characteristic indications of the progenet... Expand
Is Diurodrilus an annelid?
TLDR
On the basis of the configuration of the nervous system and the cuticle Diurodrilus is regarded to belong to Spiralia, possibly close to Annelida; however, until further evidence is acquired it should be regarded as incertae sedis in this large animal clade. Expand
Progenetic species in polychaetes (Annelida) and problems assessing their phylogenetic affiliation.

TLDR
Critical examination of morphological data that includes larval features reveals that autapomorphic characters uniting supposed progenetic taxa to specific annelid lineages are often missing, and this review summarizes the interstitial species of polychaetes for which progenetics origin has been suggested on the basis of morphology. Expand
Phylogeny and systematics of Protodrilidae (Annelida) inferred with total evidence analyses
TLDR
This comprehensive, inclusive and combined analysis revealed a new perspective on the phylogeny of Protodrilidae: the family is shown to contain six cosmopolitan subclades, each supported by several morphological apomorphies, and with the genus Astomus consistently nested among the other five clades rather than next to these.

  • 2009
TLDR
New sequence data and methods strongly uphold previous suggestions that Acoelomorpha is sister clade to all other bilaterian animals, find diminishing evidence for the placement of the enigmatic Xenoturbella within Deuterostomia, and place Cycliophora with Entoprocta and EctoproCTa. Expand
