Deep metazoan phylogeny : the backbone of the tree of life : new insights from analyses of molecules, morphology, and theory of data analysis

TLDR
This work provides the most comprehensive overview available of the state of the art in this exciting field of evolutionary research with a focus on nervous systems.
Abstract
The growing success of molecular methods has challenged traditional views of animal evolution and a large number of alternative hypotheses are hotly debated today. For the deep metazoan phylogeny project, data sets of hitherto unmatched quality and quantity were compiled and analysed with innovative bioinformatics tools. The book begins at the base of the tree of life to discuss the origin of animals and early branches of the phylogenetic tree. The following section presents special data sets gained from mitochondrial genomes and from morphology, with a focus on nervous systems. The final section is dedicated to theoretical aspects of data analysis and new bioinformatics tools. The book closes with a unique general discussion of all hypotheses contained in previous chapters. This work provides the most comprehensive overview available of the state of the art in this exciting field of evolutionary research.

Phylogenetic position of the pentastomida and [pan]crustacean relationships - eScholarship

TL;DR: Gen arrangement comparisons strongly support an unforeseen assemblage of pentastomids with maxillopod and cephalocarid crustaceans, to the exclusion of remipedes, branchiopods, malacostracans and hexapods.

Revisiting metazoan phylogeny with genomic sampling of all phyla

TL;DR: The first attempt to investigate animal relationships using genome-scale data from all phyla is presented, and matrix construction with an eye towards testing specific relationships is explored, showing that Lophotrochozoa can be constructed in strongly conflicting ways using different taxon- and/or orthologue sets.

The hidden biology of sponges and ctenophores

TL;DR: Key details of this new model hinge on a better understanding of the Porifera and Ctenophora, which have each been hypothesized to be sister to all other animals, but are poorly studied and often misrepresented.

Platyzoan Paraphyly Based on Phylogenomic Data Supports a Noncoelomate Ancestry of Spiralia

TL;DR: Platyzoan paraphyly suggests that the last common ancestor of Spiralia was a simple-bodied organism lacking coelomic cavities, segmentation, and complex brain structures, and that more complex animals such as annelids evolved from such a simply organized ancestor.
