Abstract Sponges [Porifera] are the phylogenetically oldest metazoan phylum still extant today; they share the closest relationship with the hypothetical common metazoan ancestor, the Urmetazoa. During the past 8 years cDNAs coding for proteins involved in cell-cell- and cell-tissue interaction have been cloned from sponges, primarily from Suberites domuncula and Geodia cydonium and their functions have been studied in vivo as well as in vitro. Also, characteristic elements of the extracellular… 
The chemokine networks in sponges: potential roles in morphogenesis, immunity and stem cell formation.
TLDR
The cDNAs encoding the following chemokines were described and the roles of their deduced proteins during self-self and nonself recognition outlined and it is outlined that the chemokine network was essential for the establishment of metazoans, which evolved approximately 600 to 800 million years ago.
The physiology and molecular biology of sponge tissues.
Heterologous expression of DsRed2 in young sponges (Porifera).
TLDR
Heterologously expressing the red fluorescent protein DsRedN1 under the control of the cytomegalovirus promoter in young specimens of the freshwater sponge Spongilla lacustris is succeeded, and this appealing system for early meatazoan development is considered to be ready for molecular developmental biology and functional genetics research.
Sponge non-metastatic Group I Nme gene/protein - structure and function is conserved from sponges to humans
TLDR
This study suggests that the ancestor of all animals possessed a NmeGp1 protein with properties and functions similar to evolutionarily recent versions of the protein, even before the appearance of true tissues and the origin of tumors and metastasis.
Matrix-mediated canal formation in primmorphs from the sponge Suberites domuncula involves the expression of a CD36 receptor-ligand system
TLDR
It is shown that after the transfer of primmorphs from the demosponge Suberites domuncula to a homologous matrix (galectin), canal-like structures are formed in these 3D-cell aggregates, a first indication that this secondary metabolite has a conserved functional activity: the suppression of the formation of the circulation system, from sponges to vertebrates.
The Precambrian emergence of animal life: a geobiological perspective
TLDR
It is proposed that the recorded Precambrian evolution of animals includes three intervals of advancement that begin with sponge-grade organisms, and that any preceding cryptic fauna would be no more complex than sponges.
The rhizome of life: what about metazoa?
TLDR
Whether the evolution of metazoa exists in the form of a tree, network or rhizome is highly questionable and needs to be determined.
Origin and Evolution of Marine Fungi
TLDR
Osmoheterotrophic mode of nutrition evolved independently in the Kingdom Mycetae and the Kingdom Straminipila and the sister clade alveolates shared a common ancestor, which was a mixotroph with photosynthetic and phagotrophic nutrition.
Phylogenetic Context and Basal Metazoan Model Systems1
TLDR
Hypotheses about the mechanisms underlying metazoan evolution can be drawn from the study of model organisms in Cnidaria, Ctenophora, Placozoa, and Porifera, but it is clear that these model organisms are likely to be derived in many respects, and testing these hypotheses requires theStudy of yet additional model organisms.
Oxygen-Controlled Bacterial Growth in the Sponge Suberites domuncula: toward a Molecular Understanding of the Symbiotic Relationships between Sponge and Bacteria
ABSTRACT Sponges (phylum Porifera), known to be the richest producers among the metazoans of bioactive secondary metabolites, are assumed to live in a symbiotic relationship with microorganisms,

Analysis of the sponge [Porifera] gene repertoire: implications for the evolution of the metazoan body plan.
TLDR
The primmorph system, aggregated cells that retain the capacity to proliferate and differentiate, has been used to demonstrate that a homeobox-containing gene, Iroquois, is expressed during canal formation in primmorphs, and a neuronal receptor has been identified, which indicates the existence of a primordial neuronal network already in Porifera.

Evolutionary relationships of Metazoa within the eukaryotes based on molecular data from Porifera
TLDR
It seems evident that the unicellular eukaryotes existed at an earlier stage of evolution, and the Plantae and especially the Fungi and the Metazoa only appeared later.
Molecular Evolution of the Metazoan Extracellular Matrix: Cloning and Expression of Structural Proteins from the Demosponges Suberites domuncula and Geodia cydonium
TLDR
The ligand for one of the autopomorphic characters of Metazoa, the single-transmembrane receptor protein with the receptor tyrosine kinase (RTK) from G. cydonium, is identified and it is documented that expression of the fibrous ECM molecule collagen is regulated by the characteristic metazoan morphogens myotrophin and endothelial monocyte-activating polypeptide.
Origin of metazoan adhesion molecules and adhesion receptors as deduced from cDNA analyses in the marine sponge Geodia cydonium: a review
TLDR
Analyses of the genes that are typical for multicellularity or elements involved in signal transduction pathways indicate that all animals, including sponges, are of monophyletic origin.
Sponge proteins are more similar to those of Homo sapiens than to Caenorhabditis elegans.
TLDR
Sponges are proposed as the reference animals in molecular evolutionary studies of Metazoa because they are the source of the most ancient proteins already present in the common ancestor of all multicellular organisms and some of these proteins were lost later during the evolution of individual animal lineages.
Evolution of the innate and adaptive immune systems: relationships between potential immune molecules in the lowest metazoan phylum (Porifera) and those in vertebrates.
TLDR
It is concluded that sponges are already provided with a series of elements used in higher vertebrates for both the innate and the adaptive immune recognition.
Sponge paraphyly and the origin of Metazoa
TLDR
The polymerase chain reaction is used to amplify almost the entire nucleic acid sequence of the 18S rDNA from several hexactinellid, demosponge and calcareous sponge species to suggest that sponges are paraphyletic, the Calcarea being more related to monophyletic Eumetazoa than to the siliceous spongees.
Molecular phylogeny of metazoa (animals): Monophyletic origin
TLDR
A monophyletic origin for all animals is suggested after having analyzed genes typical for multicellularity (adhesion molecules/receptors and a nuclear receptor) and presenting evidence that Porifera should be placed in the kingdom Animalia.
