    Evolution of limb development in cephalopod mollusks

    Oscar A Tarazona et al.
    Cuttlefish embryos reveal that cephalopod mollusks evolved specialized arms and tentacles by activating the same genetic circuits that control development of limbs in arthropods and vertebrates.

    'Palaeoshellomics’ reveals the use of freshwater mother-of-pearl in prehistory

    Jorune Sakalauskaite et al.
    Ancient proteomes from tiny shell ornaments were successfully characterised for the first time, showing the unexpected use of mother-of-pearl from local riverine molluscs in both coastal and inland prehistoric sites.

    Ancient origins of arthropod moulting pathway components

    André Luiz de Oliveira et al.
    Evolutionary reconstruction of the ecdysis pathway shows that its major elements are present in the majority of metazoans, providing evidence that they originated much earlier than currently assumed.

    Sexual selection gradients change over time in a simultaneous hermaphrodite

    Jeroen NA Hoffer et al.
    The quantification of sexual selection reveals that it is important to consider the chosen time frame of measurement as well as the sexual system.

  1. Living Science: Lost voices

    Eve Marder
    When a scientist dies too early in their career we miss them as a colleague and as a person and, as Eve Marder explains, we also lose the science they would have done.

    The genome of the crustacean Parhyale hawaiensis, a model for animal development, regeneration, immunity and lignocellulose digestion

    Damian Kao et al.
    The first malacostracan genome sequence will establish the genetically tractable Parhyale hawaiensis as a model organism in this key animal group.
