    Glycan-based shaping of the microbiota during primate evolution

    Sumnima Singh, Patricia Bastos-Amador ... Miguel P Soares
    Ggta1 deletion in mice shapes and reduces the microbiota pathogenicity and probably contributed to the natural selection of GGTA1 loss-of-function mutations in the ancestral primates that gave rise to humans.

    Selection for increased tibia length in mice alters skull shape through parallel changes in developmental mechanisms

    Colton M Unger, Jay Devine ... Campbell Rolian
    Artificial selection for increased tibia length in mice made their skulls longer, narrower, and flatter, suggesting that even distant skeletal regions can evolve as correlated responses to selection acting locally.

    Homoplasy in the evolution of modern human-like joint proportions in Australopithecus afarensis

    Anjali M Prabhat, Catherine K Miller ... Jeremy M DeSilva
    The human-like joint proportions of Australopithecus afarensis evolved independently, making 'Lucy' and her kind the earliest known evolutionary experiment in obligate bipedalism.

    Morphological and genomic shifts in mole-rat ‘queens’ increase fecundity but reduce skeletal integrity

    Rachel A Johnston, Philippe Vullioud ... Jenny Tung
    In cooperatively breeding Damaraland mole-rats, transitioning to 'queen' results in extensive gene regulatory and morphological remodeling, but also costs to skeletal integrity that scale with reproductive investment.

    High social status males experience accelerated epigenetic aging in wild baboons

    Jordan A Anderson, Rachel A Johnston ... Jenny Tung
    Among the factors that predict fitness in wild baboons, dominance rank in males, but not in females, is the best predictor of epigenetic aging.

    Aging: The temporary cost of dominance

    Calen P Ryan, Christopher W Kuzawa
    In a population of wild baboons, a new way to assess biological age reveals a surprising effect of social hierarchy.

    Genetic determinants facilitating the evolution of resistance to carbapenem antibiotics

    Peijun Ma, Lorrie L He ... Deborah T Hung
    High-level transposon insertional mutagenesis and a broader spectrum of resistance-conferring mutations for selected carbapenems facilitate the evolution of carbapenem resistance in Klebsiella pneumonia clinical isolates.

    Chloroplast acquisition without the gene transfer in kleptoplastic sea slugs, Plakobranchus ocellatus

    Taro Maeda, Shunichi Takahashi ... Shuji Shigenobu
    The newly opened genome of a kleptoplastic mollusk, Plakobranchus ocellatus, indicated that sequestered plastids retain their activity within the animal cell without horizontal algal gene transfer to the animal nucleus.

    Evolution of the complex transcription network controlling biofilm formation in Candida species

    Eugenio Mancera, Isabel Nocedal ... Alexander D Johnson
    The transcription networks controlling biofilm formation in Candida species exhibit 'structural' similarities, but show gradual substitutions of transcription regulators and frequent changes in target genes.

    The essential role of Dnmt1 in gametogenesis in the large milkweed bug Oncopeltus fasciatus

    Joshua T Washington, Katelyn R Cavender ... Patricia J Moore
    The maintenance DNA methyltransferase DNMT1 is required for the transition of spermatogonia to spermatocytes both during larval testis development and adult sperm replenishment in the insect Oncopeltus fasciatus.
