Phylogenetic position of Placozoa based on large subunit (LSU) and small subunit (SSU) rRNA genes
Genetics and Molecular Biology, 2007 The phylum Placozoa, represented by its single species Trichoplax adhaerens, has always been considered one of the most basal animal clades due to its low morphological complexity.

Parallel evolution of gravity sensing [PDF]
Frontiers in Cell and Developmental BiologyOmnipresent gravity affects all living organisms; it was a vital factor in the past and the current bottleneck for future space exploration. However, little is known about the evolution of gravity sensing and the comparative biology of gravity reception.

Support for a clade of Placozoa and Cnidaria in genes with minimal compositional bias
eLife, 2018 The 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 ...

Placozoa and Cnidaria are sister taxa
eLife, 2018 The 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 ...

Evolution of glial cells: a non-bilaterian perspective [PDF]
Neural DevelopmentNervous systems of bilaterian animals generally consist of two cell types: neurons and glial cells. Despite accumulating data about the many important functions glial cells serve in bilaterian nervous systems, the evolutionary origin of this abundant ...

Early Animal Origin of BACE1 APP/Aβ Proteolytic Function [PDF]
BiologyAlzheimer’s disease is characterized, in part, by the accumulation of β-amyloid (Aβ) in the brain. Aβ is produced via the proteolysis of APP by BACE1 and γ-secretase.

A taxogenomics approach uncovers a new genus in the phylum Placozoa [PDF]
bioRxiv, 2017 The Placozoa [1] is a monotypic phylum of non-bilaterian marine animals. Its only species, Trichoplax adhaerens, was described in 1883 [2], Despite the worldwide distribution of placozoans [3–6], morphological differences are lacking among isolates from ...
