    The embryonic role of juvenile hormone in the firebrat, Thermobia domestica, reveals its function before its involvement in metamorphosis

    James W Truman, Lynn M Riddiford ... Michelle Herko
    This sesquiterpene hormone likely acted as a morphogenesis-to-differentiation switch in archaic embryos before it evolved its postembryonic function as the status quo regulator of insect metamorphosis.
