Aculifera contradicts the classical morphology-based Testaria hypothesis5, which places chitons sister to Conchifera and the shell-less worm-like aplacophorans as an early-branching, paraphyletic grade. Myers, P., R. Espinosa, C. S. Parr, T. Jones, G. S. Hammond, and T. A. Dewey. What does phylogenomics really tell us about molluscan evolution? L. antarctica now is known from several stations along the shelf and slope of the Eastern Weddell and Lazarev Seas. Concentration was determined using a Qubit 2.0 Fluorometer, and 1g was used to create a sequencing library with the TruSeq DNA Sample Preparation Kit v2 (Illumina, San Diego, CA, USA) with an average insert size of approximately 250bp.

Publishers note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Ivantsov, A. Y. In order to select the best sequence for each taxon and exclude any paralogs or exogenous contamination, we built trees in FastTree 275 and used PhyloTreePruner76 to select the best sequence for each taxon. Monoplacophora (Monoplacophorans) | Encyclopedia.com However, one finding of particular interest from these studies was the recovery of a close relationship of Monoplacophora and Polyplacophora (Serialia)16,17. Surprisingly, the split of gastropods and scaphopods is rather late according to our molecular clock analysis (474 MYA; 95% HDP=479520 MYA); this could mean that many Cambrian shells currently regarded to be gastropods were actually members of the gastropod-scaphopod stem lineage. Each OG was then aligned with MAFFT71 (mafftautolocalpairmaxiterate 1000).

Resolving the evolutionary relationships of molluscs with phylogenomic tools. Relationships among Gastropoda, Bivalvia, and Scaphopoda, a clade of molluscs with relatively thick, multi-layered shells27, have been the subject of debate3,5,7,8,31 due to incongruence among recent studies18,19,20,45,46. Dataset assembly and processing built on our established and routinely used bioinformatic pipeline30,64,65,66,67 with a number of modifications to help reduce possible exogenous contamination and low quality data (e.g., incorrectly translated gene predictions from Genescan; see below). 58, 2134 (2009). Zool. Atti Conv. This resulted in a rather fragmented genome assembly (427,488 contigs >500bp; N50=2,167bp; 1.26 Gbp total assembly size). Haszprunar, G. Monoplacophora (Tryblidia). & Kocot, K. M. Improved phylogenomic sampling of free-living nematodes enhances resolution of higher-level nematode phylogeny.

Our time tree is consistent with the prevailing notion that SSFs such as helcionellids and other gastropod- and monoplacophoran-like fossils were conchiferan molluscs32, but relatively broad posterior densities preclude confident placement of these fossil taxa along any one branch.

In Phylogeny and Evolution of the Mollusca 3370 (University of California Press, 2008). Consistent with other phylogenomic studies18,19,20,50, all of our analyses strongly support a molluscan dichotomy with two major clades: Conchifera and Aculifera51.
