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 ...

Animals and Their Unicellular Ancestors [PDF]

, 2010
Animals belong to the Opisthokonta, one of the major divisions of the eukaryotic Tree of Life. This supergroup also includes other well?known groups such as fungi and choanoflagellates, in addition to some newly discovered unicellular taxa as the ...

Studying Placozoa WBR in the Simplest Metazoan Animal, Trichoplax adhaerens

, 2022
AbstractPlacozoans are a promising model system to study fundamental regeneration processes in a morphologically and genetically very simple animal. We here provide a brief introduction to the enigmatic Placozoa and summarize the state of the art of animal handling and experimental manipulation possibilities.

The origin of the Hox/ParaHox genes, the Ghost Locus hypothesis and the complexity of the first animal [PDF]

, 2015
A key aim in evolutionary biology is to deduce ancestral states in order to better understand the evolutionary origins of clades of interest and the diversification process(es) that have elaborated them.

Origin and evolution of the Rax homeobox gene by comprehensive evolutionary analysis

FEBS Open Bio, 2020
Rax is one of the key transcription factors crucial for vertebrate eye development. In this study, we conducted comprehensive evolutionary analysis of Rax.

Never ending analysis of a century old evolutionary debate: unringing the urmetazoon bell

Frontiers in Ecology and Evolution, 2016
Our understanding of the early evolution of animals will be greatly improved if a final solution can be found to the evolutionary relationships between Porifera, Placozoa, Ctenophora, Cnidaria and Bilateria.

The homeodomain complement of the ctenophore Mnemiopsis leidyi suggests that Ctenophora and Porifera diverged prior to the ParaHoxozoa

EvoDevo, 2010
Background The much-debated phylogenetic relationships of the five early branching metazoan lineages (Bilateria, Cnidaria, Ctenophora, Placozoa and Porifera) are of fundamental importance in piecing together events that occurred early in animal evolution.

Genomic data do not support comb jellies as the sister group to all other animals [PDF]

, 2015
Understanding how complex traits, such as epithelia, nervous systems, muscles, or guts, originated depends on a well-supported hypothesis about the phylogenetic relationships among major animal lineages.

Trichoplax, the simplest known animal, contains an estrogen-related receptor: Implications for the evolution of vertebrate and invertebrate estrogen receptors [PDF]

, 2008
Although, as their names imply, vertebrate and invertebrate estrogen receptors [ERs] and estrogen-related receptors [ERRs] are related transcription factors, their evolutionary relationships to each other are not fully understood.
