Social evolution : from molecules and superorganisms to flocks, shoals and parenting [Journal of Experimental Biology / Inside JEB]
No matter how small or large, from bacteria and amoebae to the planet’s largest mammals, all organisms interact socially with other members of their species. Social organisation – whether conspiring to construct vast colonies, shoaling for comfort or uniting to raise offspring, provides the infrastructure for life. However, social behaviours also have implications at the genetic level. Gene pathways can influence group dynamics and how individuals behave socially can affect the ability for genes to be passed on – it is these phenomena that fascinate Joel Levine from the University of Toronto, Canada, and Daniel Kronauer from the Rockefeller University, USA.
