Early animal evolution: a morphologist's view [PDF]
Royal Society Open Science, 2019 Two hypotheses for the early radiation of the metazoans are vividly discussed in recent phylogenomic studies, the ‘Porifera-first’ hypothesis, which places the poriferans as the sister group of all other metazoans, and the ‘Ctenophora-first’ hypothesis ...

Energy transfer within phycocyanin trimers of Mastigocladus laminosus studied by picosecond time-resolved transient absorption spectroscopy [PDF]
, 1987 The transient absorption recovery induced in phycocyanin trimers by picosecond pulses of variable wavelength (570 — 620 nm) has been recorded and analyzed by applying a least-squares multi-exponential fit procedure.

A fragmented metazoan organellar genome: the two mitochondrial chromosomes of [PDF]
, 2008 Background Animal mitochondrial (mt) genomes are characteristically circular molecules of ~16–20 kb. Medusozoa (Cnidaria excluding Anthozoa) are exceptional in that their mt genomes are linear and sometimes subdivided into two to presumably four ...

Comparative genomics and the nature of placozoan species. [PDF]
PLoS Biology, 2018 Placozoans are a phylum of nonbilaterian marine animals currently represented by a single described species, Trichoplax adhaerens, Schulze 1883. Placozoans arguably show the simplest animal morphology, which is identical among isolates collected ...

A low diversity of ANTP class homeobox genes in Placozoa
Evolution & Development, 2006 SUMMARYHomeobox genes of the ANTP and PRD classes play important roles in body patterning of metazoans, and a large diversity of these genes have been described in bilaterian animals and cnidarians.Trichoplax adhaerens(Phylum Placozoa) is a small multicellular marine animal with one of the simplest body organizations of all metazoans, showing no ...

Evo-devo of non-bilaterian animals
Genetics and Molecular Biology, 2015 The non-bilaterian animals comprise organisms in the phyla Porifera, Cnidaria, Ctenophora and Placozoa. These early-diverging phyla are pivotal to understanding the evolution of bilaterian animals.

Placozoa and Cnidaria are sister taxa
, 2017 AbstractThe phylogenetic placement of the morphologically simple placozoans is crucial to understanding the evolution of complex animal traits. Here, we examine the influence of adding new genomes from placozoans to a large dataset designed to study the deepest splits in the animal phylogeny.
