    Stone Tool Use: Monkeys overharvest shellfish

    George H Perry, Brian F Codding
    The use of stone tools by macaques in Thailand has reduced the size and population density of coastal shellfish; previously it was thought that tool-assisted overharvesting effects resulted uniquely from human activity.

    Slightly beneficial genes are retained by bacteria evolving DNA uptake despite selfish elements

    Bram van Dijk et al.
    Horizontal gene transfer (HGT) helps slightly beneficial genes persist in microbial populations, incentivising cells to invest in costly DNA uptake, even in the presence of harmful selfish genetic elements.

    wtf genes are prolific dual poison-antidote meiotic drivers

    Nicole L Nuckolls et al.
    Selfish wtf meiotic drive genes use overlapping transcripts to encode both a trans-acting poison to kill gametes that do not inherit the gene and a gamete-autonomous antidote to specifically rescue the gametes that do.

    Nutrient status shapes selfish mitochondrial genome dynamics across different levels of selection

    Bryan L Gitschlag et al.
    Food supply and nutrient stress tolerance coordinately shape the multilevel selection dynamics of a mitochondrial cheater by promoting cheater persistence at both within-host and between-host levels of selection.

    Gene Drive: A family of killers

    Mickaël De Carvalho, Sarah E Zanders
    Spok genes are meiotic drivers that increase their own chances of transmission by killing gametes that do not inherit them.

    Meiotic drive of female-inherited supernumerary chromosomes in a pathogenic fungus

    Michael Habig et al.
    Female-inherited supernumerary chromosomes that lack a male-inherited homolog are transmitted to all meiotic products instead of the expected half, which indicates an additional amplification of unpaired chromosomes during meiosis.

    Resource depletion through primate stone technology

    Lydia V Luncz et al.
    Technology-driven overharvesting of marine prey influences tool selection pattern in long tailed macaques, posing a serious threat to their behavioural traditions.

    Combinations of Spok genes create multiple meiotic drivers in Podospora

    Aaron A Vogan et al.
    Members of a single gene family determine the genomic basis of multiple coexisting meiotic drive elements in natural populations of Podospora.

    Gene flow mediates the role of sex chromosome meiotic drive during complex speciation

    Colin D Meiklejohn et al.
    Selfish genetic elements may either promote or prevent the evolution of reproductive barriers, depending on the extent of gene flow between species.
