    Metazoan evolution of glutamate receptors reveals unreported phylogenetic groups and divergent lineage-specific events

    David Ramos-Vicente et al.
    The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.

    Support for a clade of Placozoa and Cnidaria in genes with minimal compositional bias

    Christopher E Laumer et al.
    Protein coding genes strongly support a sister group relationship between Placozoa and Cnidaria to the exclusion of Bilateria, contradicting previous phylogenies, which have likely been misled by pervasive compositional heterogeneity.

    CRISPR knockouts reveal an endogenous role for ancient neuropeptides in regulating developmental timing in a sea anemone

    Nagayasu Nakanishi, Mark Q Martindale
    Analysis of the endogenous function of deeply conserved neuropeptides in sea anemones sheds light on a primitive role of nervous systems in modulating developmental timing.

    Germ layer-specific regulation of cell polarity and adhesion gives insight into the evolution of mesoderm

    Miguel Salinas-Saavedra et al.
    The expression of 'bilaterian-mesodermal’ genes changes the epithelial properties of the endomesoderm during the embryogenesis of the cnidarian Nematostella vectensis.

    The last common ancestor of animals lacked the HIF pathway and respired in low-oxygen environments

    Daniel B Mills et al.
    Sponges and ctenophores lack hypoxia-inducible factors, suggesting that the metazoan last common ancestor could have lived aerobically under severe hypoxia and did not need to regulate its transcription in response to oxygen availability.

    Evolution: Oxygen and early animals

    Kalle T Rytkönen
    The biology of sponges provides clues about how early animals may have dealt with low levels of oxygen.

    Beyond excitation/inhibition imbalance in multidimensional models of neural circuit changes in brain disorders

    Cian O'Donnell et al.
    Computational modeling and analysis of mouse neural population data finds that the excitation/inhibition imbalance theory of brain disorders is too limited to account for key changes in neural activity statistics.

    The E3 ubiquitin ligase IDOL regulates synaptic ApoER2 levels and is important for plasticity and learning

    Jie Gao et al.
    Control of lipoprotein receptor protein levels at synapses by the E3 ubiquitin ligase IDOL is shown to be important for the plasticity of neuronal dendrites in vitro and learning and memory in mice.

    Ingression-type cell migration drives vegetal endoderm internalisation in the Xenopus gastrula

    Jason WH Wen, Rudolf Winklbauer
    The cellular behaviours that underlie the internalization of the multilayered endoderm anlage in Xenopus laevis link the ancestral mode of vertebrate gastrulation to common, epithelial-based mechanisms of gastrulation in non-vertebrate animals.
