TL;DR: There is no single road map to eusociality; independent evolutionary transitions in sociality have independent genetic underpinnings and these transitions do have similar general features, including an increase in constrained protein evolution accompanied by increases in the potential for gene regulation and decreases in diversity and abundance of transposable elements.

TL;DR: It is suggested that behavioural changes were not associated with decreased hyena population density, which suggests the behavioural plasticity typical of this species may protect it from extinction.

TL;DR: The results support the idea that host-symbiont dynamics influence microbiome composition and, reciprocally, host social behavior and propose that the two types of workers, which have the highest diversity of operational taxonomic units (OTUs) of bacteria, are central to the maintenance of the colony microbiome.

TL;DR: This work defines this effect as ‘social heterosis’, and mathematically demonstrate maintenance of allelic diversity when diverse groups or neighbourhoods are more reproductively successful than homogenous ones.

TL;DR: In this article, the authors examined predictions of hypotheses suggesting that space use by female hyenas is affected by reproductive state, social rank, and local prey abundance, and found that females with den-dwelling cubs had smaller home ranges, were found closer to the communal den, and were found farther from the territorial boundary than were females with no cubs.
