Within animal populations there is variation among individuals in their tendency to be social,
where more sociable individuals associate more with other individuals. Consistent inter …

Despite substantial progress in understanding the genetic basis for differences in
morphology, physiology, and behavior, many phenotypes of interest are difficult to study with …

Sweat bees have repeatedly gained and lost eusociality, a transition from individual to group
reproduction. Here we generate chromosome-length genome assemblies for 17 species …

The honeybee possesses a limited number of bacterial phylotypes that play essential roles
in host metabolism, hormonal signaling, and feeding behavior. However, the contribution of …

A key mechanistic hypothesis for the evolution of division of labour in social insects is that a
shared set of genes co-opted from a common solitary ancestral ground plan (a genetic …

Highlights•The gut microbiota is emerging as a regulator of neurophysiology and
behavior.•Similar processes may govern the gut microbiota—brain axis across mammals …

Autism spectrum disorder (ASD) is typically characterized by common deficits in social skills
and repetitive/stereotyped behaviors. It is widely accepted that genetic and environmental …

Although indirect selection through relatives (kin selection) can explain the evolution of
effectively sterile offspring that act as helpers at the nest (eusociality) in the ants, bees, and …

An animal's social behaviour both influences and changes in response to its parasites. Here
we consider these bidirectional links between host social behaviours and parasite infection …

Nervous systems allow animals to acutely respond and behaviorally adapt to changes and
recurring patterns in their environment at multiple timescales—from milliseconds to years …
