Shared genetic mechanisms underpin social life in bees and humans, study suggest

alternative_right writes: In social species, there is individual variation in sociability—some individuals are highly social and well-connected within their society, whereas others prefer less social interaction. This variation can be driven by many factors, including mood, social status, previous experience, and genetics. However, the genetic and molecular mechanisms that influence sociability are poorly understood.

Sociability is a complex characteristic, controlled by many genes, but these shared genomic features suggest there are ancient molecular building blocks of social life that have been conserved through millions of years of evolution, even if humans and bees evolved social life independently, the authors say.

The authors add, "It is a central feature of all societies that group members often engage with one another, but vary in their tendency to do so. Combining automated monitoring of social interactions, DNA sequencing, and brain transcriptomics in honey bee colonies, we identified evolutionarily conserved molecular roots of sociability shared across phylogenetically distinct species, including humans."
