    The origin of the odorant receptor gene family in insects

    Philipp Brand et al.
    The insect odorant receptor gene family evolved at the base of the class Insecta before the evolution of flight and perhaps as an adaptation to terrestriality, and was therefore an important evolutionary novelty for insects.

    Apicomplexan-like parasites are polyphyletic and widely but selectively dependent on cryptic plastid organelles

    Jan Janouškovec et al.
    Apicomplexan-like parasites originated several times independently and many of them contain cryptic plastid organelles, which demonstrate that the parasites evolved from photosynthetic algae.

    Preservation of three-dimensional anatomy in phosphatized fossil arthropods enriches evolutionary inference

    Achim H Schwermann et al.
    X-ray imaging reveals well-preserved internal characters in mineralized arthropods from the Paleogene, urging the reexamination of previously neglected fossil collections.

    The genome of an intranuclear parasite, Paramicrosporidium saccamoebae, reveals alternative adaptations to obligate intracellular parasitism

    C Alisha Quandt et al.
    Parasitic lineages of Rozellomycota are shaped by repeated and independent gene losses.

    Brood care in a 100-million-year-old scale insect

    Bo Wang et al.
    The discovery of the earliest direct evidence of brood care in insects demonstrates a remarkably conserved egg-brooding reproductive strategy within scale insects in stasis for nearly 100 million years.

    Nuclear genomic signals of the ‘microturbellarian’ roots of platyhelminth evolutionary innovation

    Christopher E Laumer et al.
    A phylogeny of all major groups of flatworms based on hundreds of genes sheds new light the early evolution of this important metazoan phylum, with particular significance for the original of vertebrate parasitism.

    The evolution of the vestibular apparatus in apes and humans

    Alessandro Urciuoli et al.
    The morphology of the inner ear distinguishes major anthropoid clades and enables the proposal of various shared-derived features for apes as a whole, lesser apes, and great apes and humans.

    A non-archaeopterygid avialan theropod from the Late Jurassic of southern Germany

    Oliver WM Rauhut et al.
    A new taxon from the Late Jurassic of southern Germany represents the second volant bird known from that time period and documents the improvement of flapping flight in bird evolution.

    Oldest skeleton of a fossil flying squirrel casts new light on the phylogeny of the group

    Isaac Casanovas-Vilar et al.
    Flying squirrels may have originated earlier than previously thought and remained unchanged for almost 12 million years.
