The phylogenetic relationships of the Scaphopoda, one of the ‘lesser’ molluscan classes, with the other conchiferan taxa are far from clear. They appear either as the sister‐group to the Bivalvia (Diasoma concept) or to a Gastropoda–Cephalopoda clade or to the Cephalopoda alone (helcionellid concept). We compiled a 18S rDNA sequence dataset of 48 molluscan species containing 17 scaphopods to test these hypotheses and to address questions regarding high‐level relationships with the Scaphopoda… Expand
Vetigastropod phylogeny and a new concept of Seguenzioidea: independent evolution of copulatory organs in the deep‐sea habitats
TLDR
Bayesian and maximum‐likelihood phylogenies of Vetigastropoda were reconstructed by separate and combined analyses of one mitochondrial, one nuclear and two nuclear gene sequences, with an emphasis on dense taxonomic sampling. Expand
The Continuing Debate on Deep Molluscan Phylogeny: Evidence for Serialia (Mollusca, Monoplacophora + Polyplacophora)
TLDR
A new molecular clock indicates that molluscs had a terminal Precambrian origin with rapid divergence of all eight extant classes in the Cambrian, and the recovery of Serialia as a derived, Late Cambrian clade is potentially in line with the stratigraphic chronology of morphologically heterogeneous early mollusc fossils. Expand
Molecular phylogenetic investigations of the relationships of the echinoderm-parasite family Eulimidae within Hypsogastropoda (Mollusca).
TLDR
Bayesian and maximum likelihood phylograms of Hypsogastropoda based on nuclear and mitochondrial loci and a better taxonomic sampling than in previous molecular analyses suggest Vanikoridae as the sister group of Eulimidae; the two families are collectively placed in the newly redefined superfamily Vanikoroidea. Expand
Molecular phylogeny of Anomalodesmata (Mollusca: Bivalvia) inferred from 18S rRNA sequences
TLDR
Tests of various alternative topologies showed that all are significantly longer but optimal likelihood trees with monophyletic carnivorous taxa and/or Thraciidae are not significantly less likely andPalaeontological data and homology decisions for selected characters are evaluated in the light of the molecular trees. Expand
Evidence for a clade composed of molluscs with serially repeated structures: Monoplacophorans are related to chitons
TLDR
The first molecular data on monoplacophorans, analyzed together with the largest data set of molluscs ever assembled, clearly illustrate that monoplacs and chitons form a clade and may have important implications for metazoan evolution. Expand
Molecular phylogeny of Maldanidae (Annelida): Multiple losses of tube-capping plates and evolutionary shifts in habitat depth.
TLDR
A molecular phylogeny using 52 maldanid species from six subfamilies based on two nuclear genes and 28S rDNA and two mitochondrial genes suggested that habitat shifts among depth zones frequently occurred in distinct maldinid lineages. Expand
The complete sequence and gene organization of the mitochondrial genome of the gadilid scaphopod Siphonondentalium lobatum (Mollusca).
TLDR
The deep molluscan phylogeny is probably beyond the resolution of mitochondrial protein sequences, and assessing the phylogenetic signal in gene order data requires a much larger taxon sample than is currently available, given the exceptional diversity of this character set in the Mollusca. Expand
The Testaria concept (Polyplacophora + Conchifera) updated
TLDR
A critical review of arguments of both hypotheses in the light of present evidence is presented, pointing out the plesiomorphic nature of many morphological similarities among the aculiferan taxa and in relation to Conchifera. Expand
Recent Advances and Unanswered Questions in Deep Molluscan Phylogenetics*
TLDR
Three recent molecular phylogenetic studies employing different markers and more data have significantly advanced understanding of molluscan phylogeny by providing well-supported topologies and generally congruent results, counter the widely held view that Gastropoda and Cephalopoda are sister taxa. Expand
Investigation of molluscan phylogeny using large-subunit and small-subunit nuclear rRNA sequences.
TLDR
Although the LSU and combined LSU+SSU datasets appear to hold potential for resolving branching order within the recognized molluscan classes, low bootstrap support was found for relationships between the major lineages within the Mollusca. Expand

Phylogenetic relationships among families of the Scaphopoda (Mollusca)
TLDR
The relationships supported here provide a working hypothesis that the development of new characters and greater breadth of taxonomic sampling can test, with a suggested primary goal of establishing monophyly at the family level. Expand
Investigation of molluscan phylogeny on the basis of 18S rRNA sequences.
TLDR
These data do not provide support for a close relationship between Platyhelminthes (Turbellaria) and Mollusca, but suggest that the latter group belongs to a clade of eutrochozoan coelomates, and obtain strong preliminary support for phylogenetic inferences at more restricted taxonomic levels. Expand
The phylogeny and classification of Scaphopoda (Mollusca): an assessment of current resolution and cladistic reanalysis
TLDR
Reanalysis only clearly resolves monophyly of the Gadilida and the sister relationship of the Entalinidae with the remaining gadilid families, and the need for more comparative data and thorough parsimony analysis in scaphopod cladistic phylogenetics, as relationships in this class are still some way from resolution. Expand
Details of gastropod phylogeny inferred from 18S rRNA sequences.
TLDR
The present study provides new molecular evidence for the monophyly of both Caenogastropoda and Euthyneura (Pulmonata and Opisthobranchia), making Prosobranchia paraphyletic, and suggests that Systellommatophora are not a monophyletic unit. Expand
Triploblastic relationships with emphasis on the acoelomates and the position of Gnathostomulida, Cycliophora, Plathelminthes, and Chaetognatha: a combined approach of 18S rDNA sequences and morphology.
TLDR
For the first time, a data analysis recognizes a clade of acoelomates, the Platyzoa, which is expanded to include the enigmatic phylum Cycliophora, as sister group to Syndermata. Expand

  • 2000
TLDR
Phylogenetic analyses including nearly complete bivalve small-subunit rRNA sequences demonstrate support for the monophyly of the family Mytilidae and the subfamilies Crenellinae and Lithophaginae, however, theSubfamilies Mytilinee and Modiolinae appear polyphyletic. Expand
What Can 18S rDNA Do for Bivalve Phylogeny?
TLDR
A ‘‘preferred tree’’ is proposed combining the results from the 18S rDNA data and morphological characters compiled by Waller (1978, 1990) combined with an evaluation of hypotheses on bivalve phylogeny from the given morphological and molecular trees. Expand

TLDR
This is the first documented case of convergent anatomical features among Scaphopoda and enhances the need of radula and soft part investigation of the conchologically little informative, smooth-shelled dentaliid groups. Expand

Abstract. Bivalve classification has suffered in the past from the crossed-purpose discussions among paleontologists and neontologists, and many have based their proposals on single characterExpand
