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.
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.
Technology-driven overharvesting of marine prey influences tool selection pattern in long tailed macaques, posing a serious threat to their behavioural traditions.
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.
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.
A novel assay to measure 2-micron stability together with a survey of natural variation among Saccharomyces cerevisiae strains reveals novel means by which yeasts can combat the parasitic 2-micron plasmids.
A female specifically expressed new protein-coding gene that has emerged out of non-coding sequences without detectable signatures of adaptive evolution affects female pregnancy cycles.
