Abstract

we describe a possible link between coordinated lateralised group behaviour serving species survival in lower vertebrates and a striking lateralisation phenomenon found in human social behaviour: the universal preference for cradling a young infant on the left side. our exploration offers a different perspective on the role of cerebral asymmetry for the survival of both the individual and the species.
