    Characterization of TSET, an ancient and widespread membrane trafficking complex

    Jennifer Hirst et al.
    A missing link between the AP complexes and COPI sheds light on the evolution of vesicle coat proteins and trafficking pathways in the earliest eukaryotes.

    Punctuated evolution and transitional hybrid network in an ancestral cell cycle of fungi

    Edgar M Medina et al.
    Cell cycle network evolution in a fungal ancestor was punctuated by the arrival of a viral DNA-binding protein that was permanently incorporated into the regulatory network controlling cell cycle entry.

    Evolution of alternative biosynthetic pathways for vitamin C following plastid acquisition in photosynthetic eukaryotes

    Glen Wheeler et al.
    Genomic evidence suggests that L-gulonolactone oxidase-the terminal enzyme in vitamin C synthesis, which has been repeatedly lost throughout animal evolution-was lost in plants and other photosynthetic eukaryotes following plastid acquisition.

    Microbial eukaryotes have adapted to hypoxia by horizontal acquisitions of a gene involved in rhodoquinone biosynthesis

    Courtney W Stairs et al.
    A number of microbial eukaryotes have adapted to low oxygen conditions by acquiring a gene that allows their mitochondrial electron transport chain to continue to function when oxygen is scarce.

    Complex transcriptional regulation and independent evolution of fungal-like traits in a relative of animals

    Alex de Mendoza et al.
    Functional genomics reveal complex genome regulation during the coenocytic development of the ichthyosporean Creolimax fragrantissima, a protist closely related to animals.

    Epsin deficiency impairs endocytosis by stalling the actin-dependent invagination of endocytic clathrin-coated pits

    Mirko Messa et al.
    Epsin has a key role in the coupling of actin to endocytic clathrin coated pits that is required for their maturation and helps capture SNAREs at endocytic clathrin coated pits.

    Collagen IV and basement membrane at the evolutionary dawn of metazoan tissues

    Aaron L Fidler et al.
    Collagen IV is a primordial extracellular matrix component associated with the transition to animal multicellularity, and enabled the formation and evolution of epithelial tissues.

    Chromerid genomes reveal the evolutionary path from photosynthetic algae to obligate intracellular parasites

    Yong H Woo et al.
    Analysis of chromerid algal genomes reveals how apicomplexans have evolved from free-living algae into successful eukaryotic parasites via massive losses and re-inventing functional roles of genes.

    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.
