A pre-metazoan origin of the CRK gene family and co-opted signaling network. [PDF]
, 2016 CRK and CRKL adapter proteins play essential roles in development and cancer through their SRC homology 2 and 3 (SH2 and SH3) domains. To gain insight into the origin of their shared functions, we have investigated their evolutionary history.

Hidden cell diversity in Placozoa: ultrastructural insights from Hoilungia hongkongensis
Cell and Tissue Research, 2020 From a morphological point of view, placozoans are among the most simple free-living animals. This enigmatic phylum is critical for our understanding of the evolution of animals and their cell types.

Evolutionary origin of synapses and neurons – Bridging the gap [PDF]
, 2017 The evolutionary origin of synapses and neurons is an enigmatic subject that inspires much debate. Non-bilaterian metazoans, both with and without neurons and their closest relatives already contain many components of the molecular toolkits for ...

Multiple surveys employing a new sample‐processing protocol reveal the genetic diversity of placozoans in Japan [PDF]
, 2018 Placozoans, flat free‐living marine invertebrates, possess an extremely simple bauplan lacking neurons and muscle cells and represent one of the earliest‐branching metazoan phyla. They are widely distributed from temperate to tropical oceans.

Evolutionary Applications, Volume 19, Issue 5, May 2026.ABSTRACT Crustaceans, such as shrimp and crabs, are pivotal to global aquaculture, yet their productivity is severely impacted by low‐temperature stress. This study employs comparative transcriptomic and genomic analyses to elucidate the molecular mechanisms underlying crustacean responses to cold stress across five economically significant species ...

New genomic data and analyses challenge the traditional vision of animal epithelium evolution
BMC Genomics, 2018 Background The emergence of epithelia was the foundation of metazoan expansion. Epithelial tissues are a hallmark of metazoans deeply rooted in the evolution of their complex developmental morphogenesis processes.

Amino acids integrate behaviors in nerveless placozoans
Frontiers in Neuroscience, 2023 Placozoans are the simplest known free-living animals without recognized neurons and muscles but a complex behavioral repertoire. However, mechanisms and cellular bases of behavioral coordination are unknown.

Distinct expression patterns of the two T-box homologues Brachyury and Tbx2/3 in the placozoan Trichoplax adhaerens [PDF]
, 2018 Trichoplax adhaerens is the only species known from the phylum Placozoa with one of the simplest metazoan body plans. In the small disc-like organism an upper and a lower epithelium can be distinguished with a less compact third cell layer in between ...

Differentiation of Crystal Cells, Gravity-Sensing Cells in the Placozoan Trichoplax adhaerens
Journal of Marine Science and Engineering, 2021 Trichoplax adhaerens are simple animals with no nervous system, muscles or body axis. Nevertheless, Trichoplax demonstrate complex behaviors, including responses to the direction of the gravity vector.

Rotiferan Hox genes give new insights into the evolution of metazoan bodyplans [PDF]
, 2017 The phylum Rotifera consists of minuscule, nonsegmented animals with a unique body plan and an unresolved phylogenetic position. The presence of pharyngeal articulated jaws supports an inclusion in Gnathifera nested in the Spiralia.
