Aplacophoran mollusks evolved from ancestors with polyplacophoran-like features
Mollusca is an animal phylum with vast morphological diversity and includes worm-shaped aplacophorans, snails, bivalves, and the complex cephalopods . The interrelationships of these class-level taxa are still contentious ...
Development of the nervous system in Solenogastres (Mollusca) reveals putative ancestral spiralian features
(BioMed Central, 2014-12-24)
Background: The Solenogastres (or Neomeniomorpha) are a taxon of aplacophoran molluscs with contentious phylogenetic placement. Since available developmental data on non-conchiferan (that is, aculiferan) molluscs mainly ...
Ancestral role of Pax2/5/8 in molluscan brain and multimodal sensory system development
(BioMed Central, 2015-10-28)
Background Mollusks represent the largest lophotrochozoan phylum and exhibit highly diverse body plans. Previous studies have demonstrated that transcription factors such as Pax genes play important roles during their ...
From complex to simple: myogenesis in an aplacophoran mollusk reveals key traits in aculiferan evolution
(BioMed Central, 2015-09-18)
Background Recent studies suggest a bifurcation at the base of Mollusca, resulting in the primarily single-shelled Conchifera (Bivalvia, Gastropoda, Scaphopoda, Monoplacophora, Cephalopoda) and the spicule-bearing Aculifera ...
