    Morphometric analysis of lungfish endocasts elucidates early dipnoan palaeoneurological evolution

    Alice M Clement, Tom J Challands ... John A Long
    Cranial endocasts of fossil and extant lungfish, analysed via tomography and novel principle component analyses designed for use with missing data, show that lungfish forebrain and inner ear regions show the most variation in brain shape evolution through time.

    The evolutionary history of human spindle genes includes back-and-forth gene flow with Neandertals

    Stéphane Peyrégne, Janet Kelso ... Svante Pääbo
    Analyses of spindle genes with missense changes in modern humans reveal evidence for positive selection since the split with archaic humans and show that modern humans interacted with Neandertals more than once in the past 200,000 years.

    Host-parasite coevolution promotes innovation through deformations in fitness landscapes

    Animesh Gupta, Luis Zaman ... Justin R Meyer
    An interdisciplinary approach combining high throughput genotype-to-phenotype mapping, population genetic simulations, and experimental evolution provides an answer to the question of how populations evolve new functions by providing tests of the role antagonistic coevolution plays in pressuring populations to innovate.

    An epithelial signalling centre in sharks supports homology of tooth morphogenesis in vertebrates

    Alexandre P Thiery, Ariane SI Standing ... Gareth J Fraser
    The development of diverse tooth shapes among vertebrates, from sharks to mammals, is a highly conserved process, utilising a similar dental signalling centre for more than 400 million years.

    Tooth Development: What sharks and mammals share

    Sophie Pantalacci
    The tooth shape of sharks and mice are regulated by a similar signaling center despite their teeth having very different geometries.

    Evolutionary convergence of a neural mechanism in the cavefish lateral line system

    Elias T Lunsford, Alexandra Paz ... James C Liao
    The underlying neurophysiology of the lateral line system in blind cavefish (Astyanax mexicanus) has evolutionarily converged on elevated afferent neuron activity and partial loss of function in inhibitory efferent neurons, both of which contribute to enhanced sensitivity to flow stimuli.

    Admixture of evolutionary rates across a butterfly hybrid zone

    Tianzhu Xiong, Xueyan Li ... James Mallet
    Genetic barriers to gene flow maintain divergent linked substitution rates in hybridization.

    Sequence and structural conservation reveal fingerprint residues in TRP channels

    Deny Cabezas-Bratesco, Francisco A Mcgee ... Sebastian E Brauchi
    Joint sequence, structure, and phylogenetic analyses identify highly conserved features in transmembrane domains of transient receptor potential (TRP) ion channel proteins that offer a novel explanation for how TRPs could integrate stimuli into cellular signals.

    Gill developmental program in the teleost mandibular arch

    Mathi Thiruppathy, Peter Fabian ... J Gage Crump
    Lineage tracing and genetic analysis in zebrafish show that the pseudobranch is a serial homolog of the gills arising from the jaw-forming mandibular arch, thus supporting the model that vertebrate jaws derived from an ancestral mandibular gill.

    Understanding drivers of phylogenetic clustering and terminal branch lengths distribution in epidemics of Mycobacterium tuberculosis

    Fabrizio Menardo
    Populations of Mycobacterium tuberculosis associated with clustering and shorter terminal branches are not necessarily transmitting more.
