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.

A toxin-antidote element, identified for its role as a selfish genetic element that spreads through a population by killing certain offspring, also plays a beneficial role to the host.

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.

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

African haplotypes of a meiotic drive supergene in Drosophila melanogaster called Segregation Distorter show signs of a recent selective sweep, reduced recombination, and increased genetic load.

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.

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

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.

The wtf family of meiotic drivers has maintained the capacity to cause meiotic drive for over 100 million years.

By considering a new form of social cheat strategy, arms-races-like dynamics between coevolving selfish traits could emerge from the tragedy of the commons and help explain the variations in cheating levels observed in many microbes and eusocial insects.
