As arguably the simplest free-living animals, placozoans may represent a primitive metazoan form, yet their biology is poorly understood. Here we report the sequencing and analysis of the ∼98 million base pair nuclear genome of the placozoan Trichoplax adhaerens. Whole-genome phylogenetic analysis suggests that placozoans belong to a ‘eumetazoan’ clade that includes cnidarians and bilaterians, with sponges as the earliest diverging animals. The compact genome shows conserved gene content, gene… 
The Amphimedon queenslandica genome and the evolution of animal complexity
TLDR
Comparative analysis enabled by the sequencing of the sponge genome reveals genomic events linked to the origin and early evolution of animals, including the appearance, expansion and diversification of pan-metazoan transcription factor, signalling pathway and structural genes.
The Capsaspora genome reveals a complex unicellular prehistory of animals
TLDR
It is proposed that the acquisition of these metazoan-specific developmental systems and the co-option of pre-existing genes drove the evolutionary transition from unicellular protists to metazoans.
Comparative genomics and the nature of placozoan species
TLDR
The multilevel comparative genomics approach is likely to prove valuable for species distinctions in other cryptic microscopic animal groups that lack diagnostic morphological characters, such as some nematodes, copepods, rotifers, or mites.
The enigmatic Placozoa part 1: Exploring evolutionary controversies and poor ecological knowledge
TLDR
The placozoan Trichoplax adhaerens offers unique prospects for understanding the minimal requirements of metazoan animal organization and their corresponding malfunctions.
Early origin of the bilaterian developmental toolkit
  • D. Erwin
  • Biology
    Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2009
TLDR
It is suggested that placozoans and cnidarians represent a depauperate residue of a once more diverse assemblage of early animals, some of which may be represented in the Ediacaran fauna (c. 585–542 Myr ago).
The Early ANTP Gene Repertoire: Insights from the Placozoan Genome
TLDR
The complete genome of Trichoplax adhaerens, representing the basal metazoan phylum Placozoa, is analyzed for its set of ANTP class genes and the evolution of the cnidarian and bilaterian ANTP gene repertoires can be deduced by a limited number of cis-duplications of NKL and “extended Hox” genes.
The genome of the jellyfish Aurelia and the evolution of animal complexity
TLDR
RNA sequencing analysis does not support the hypothesis that taxonomically restricted (orphan) genes play an oversized role in the development of the medusa stage, and suggests that genes broadly conserved across animals and eukaryotes play comparable roles throughout the life cycle.
Global Diversity of the Placozoa
TLDR
There is great potential and need to erect new taxa and to establish a firm system for this taxonomic tabula rasa within this phylum.
The genome of the contractile demosponge Tethya wilhelma and the evolution of metazoan neural signalling pathways
TLDR
Changes in gene content are consistent with the view that ctenophores and sponges are the earliest-branching metazoan lineages and provide additional support for the proposed clade of Placozoa/Cnidaria/Bilateria.

Sea Anemone Genome Reveals Ancestral Eumetazoan Gene Repertoire and Genomic Organization
TLDR
A comparative analysis of the draft genome of an emerging cnidarian model, the starlet sea anemone Nematostella vectensis, suggests that gene “inventions” along the lineage leading to animals were likely already well integrated with preexisting eukaryotic genes in the eumetazoan progenitor.
The Early ANTP Gene Repertoire: Insights from the Placozoan Genome
TLDR
The complete genome of Trichoplax adhaerens, representing the basal metazoan phylum Placozoa, is analyzed for its set of ANTP class genes and the evolution of the cnidarian and bilaterian ANTP gene repertoires can be deduced by a limited number of cis-duplications of NKL and “extended Hox” genes.
Comparative Genomics of Large Mitochondria in Placozoans
TLDR
The similarities in composition and structure between the three mitochondrial genomes reported here and that of Trichoplax's mtDNA suggest that their uncompacted state is a shared ancestral feature to other nonmetazoans while their gene content is a derived feature shared only among the Metazoa.
The amphioxus genome and the evolution of the chordate karyotype
TLDR
Whole-genome comparisons illuminate the murky relationships among the three chordate groups (tunicates, lancelets and vertebrates), and allow not only reconstruction of the gene complement of the last common chordate ancestor but also partial reconstruction of its genomic organization.
Mitochondrial genome of Trichoplax adhaerens supports placozoa as the basal lower metazoan phylum.
TLDR
The Trichoplax mtDNA has characteristics of the mitochondrial genomes of known metazoan outgroups, such as chytrid fungi and choanoflagellates, but, more importantly, it shares derived features unique to the Metazoa.
Placozoa are not derived cnidarians: evidence from molecular morphology.
TLDR
The new molecular morphological characters provide compelling evidence that Trichoplax is not a derived (medusozoan) cnidarian, and it was found that the mitochondrial genome in Cubozoa consists of four linear molecules instead of a single circular molecule or two linear molecules, suggesting that the cubozoans may represent the most derived cNidarian group.
My favorite animal, Trichoplax adhaerens.

TLDR
The interest of zoologists and evolutionary biologists suddenly vanished for more than half a century when Trichoplax was claimed to be an aberrant hydrozoan planula larva and has been rediscovered as a key species for unraveling early metazoan evolution.
A low diversity of ANTP class homeobox genes in Placozoa
TLDR
The low diversity of ANTP class genes isolated in Trichoplax can be reconciled with the low anatomical complexity of this animal, although the finding that these genes are assignable to recognized gene families is intriguing.
Placozoa – no longer a phylum of one
The evolution of the placozoa: A new morphological model
TLDR
The evolutionary history of the placozoanTrichoplax adhaerens is reconstructed from a hypothetical ‘gallertoid’ ancestor and the given reconstruction provides some specifications for the gallertoid model.
