    Squamation and scale morphology at the root of jawed vertebrates

    Yajing Wang, Min Zhu
    New morphological data of a primitive placoderm fish demonstrate both high regionalization of squamation and the bipartite histological structure of scale are plesiomorphic for jawed vertebrates.

    Alone, in the dark: The extraordinary neuroethology of the solitary blind mole rat

    Yael Kashash et al.
    A new ethologically relevant model for investigating the neurobiology of solitary, asocial behavior in the blind mole rat.

    Palatal morphology predicts the paleobiology of early salamanders

    Jia Jia et al.
    Salamanders originate as metamorphosed with a biphasic lifestyle as shown by the palate shape and several non-shape features associated with the vomerine teeth, with diverse ecological types displayed in living species achieved in the Early Cretaceous.

    Genome editing in the unicellular holozoan Capsaspora owczarzaki suggests a premetazoan role for the Hippo pathway in multicellular morphogenesis

    Jonathan E Phillips et al.
    Genome editing in a close unicellular relative of animals suggests a premetazoan function of the Hippo pathway effector YAP/TAZ/Yorkie in the regulation of cytoskeletal dynamics and multicellular morphogenesis but not proliferation.

    Neocortical pyramidal neurons with axons emerging from dendrites are frequent in non-primates, but rare in monkey and human

    Petra Wahle et al.
    Archived histological material from tracing studies, immunohistochemistry, and Golgi impregnations allowed to discover a so far unrecognized structural difference, potentially of functional importance, between neocortical pyramidal neurons of rodent, carnivore, and ungulate as compared to monkey and man.

    Pyramidal Neurons: Looking for the origins of axons

    Kathleen S Rockland
    Pyramidal neurons with axons that exit from dendrites rather than the cell body itself are relatively common in non-primates, but rare in monkeys and humans.

    Proposing a neural framework for the evolution of elaborate courtship displays

    Ryan W Schwark et al.
    The midbrain periaqueductal grey is a conserved mediator of elaborate courtship behavior in a range of vertebrate taxa, likely shaping how this behavior diversifies across the tree of life.

    Male rat leukocyte population dynamics predict a window for intervention in aging

    Hagai Yanai et al.
    Rat blood profiles support non-linear aging with distinct trajectory shifts, and these profiles could be used to predict non-overt illness in rats or aging intervention efficacy.
