Analyses of allelic- and socially-biased gene expression reveal that suppressed recombination causes most of the expression differences in the social supergene, with only few differences due to socially antagonistic selection.
A mathematical model for a popular biological diversity mechanism, cyclic dominance, is more likely to emerge by assembly than by evolutionary diversification, which rationalizes why few empirically studies find it.
The earliest fossil evidence of a mimetic relationship between the Jurassic moth lacewing Lichenipolystoechotes and its co-occurring fossil lichen Daohugouthallus predates modern lichen-insect associations by 165 million years.
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.

Population genetics in turquoise killifish wild populations reveals how small population size and genetic drift determine the accumulation of deleterious gene variants leading to short lifespan.
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.
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.
