New evidence that neighboring communities of bonobos hunt different prey species, despite extensive overlaps in where they live and hunt, is difficult to explain without invoking cultural factors.
Bonobo groups that share overlapping ranging areas and engage in regular social exchange show "behavioural group identity" of hunting techniques in the absence of local ecological variation.
Identifying why statins differ from other major lipid modifiers has revealed a new modifiable target of intervention for cardiovascular disease relevant to both drug development and optimal statin use.
Evidence is mounting that environmentally-induced adaptive changes in phenotype can be transmitted across generations, but mechanistic gaps and theoretical concerns must be addressed to impact mainstream views of evolutionary adaptation.
Even though the ctenophore Mnemiopsis leidyi develops polarized epithelial tissues, polarization is not mediated by the conserved mechanisms polarizing bilaterian and cnidarian epithelial cells.

The stdpopsim library, a community-driven open source project, is presented which provides easy access to a standard catalog of published simulation models for population genetics aimed at field-wide standardization.
Temperature, the presence of an enemy species and the density of the mutualistic partner species interact to determine the expression of a protective mutualism.

Once an influenza infection is established, selection acts efficiently in favouring fitter viral genotypes, its effects being limited only by the short length of a typical infection.
