    Sea Lions Develop Human-like Vernix Caseosa Delivering Branched Fats and Squalene to the GI Tract

    Scientific Reports 8: 7478

    VC (the white waxy coating found on newborn human skin) is thought to be a uniquely human substance.
    Its signature characteristic is exceptional richness in saturated branched chain fatty acids BCFA & squalene SQ.
    VC particles sloughed from the skin suspended in amniotic fluid are swallowed by the human fetus, depositing BCFA/SQ throughout the gastro-intestinal tract, establishing a unique microbial niche, that influences development of nascent microbiota.

    Here we show:
    late-term California sea lion Zalophus californianus fetuses have true VC, delivering BCFA & SQ to the fetal GI-tract, recapitulating the human fetal gut microbial niche.
    These are the first data demonstrating the production of true VC in a species other than H.sapiens.
    Its presence in a marine mammal supports the hypothesis of an aquatic habituation period in the evolution of modern humans.

    See my comments on the article (I completely forgot).

    Ceterum censeo:
    only incredible idiots believe their ancestors ran after antelopes.

    Sea lions have extremely dense pelage, the opposite of Homo.
    VC may be in many other fauna where the newborns are exposed to cool damp conditions.
