COVER An alpine newt (Ichthyosaura alpestris) walks to a breeding pond in the Alps, France. Many amphibians have a cryptic upper side but a normally concealed, conspicuous underside. These hidden signals have evolved for several reasons, including as a warning display to would-be predators. A phylogenetic analysis reveals that species with hidden colors represent an important intermediate step in the evolution of species with permanently displayed warning signals. See page 1136.
