Sue Carter of the University of North Carolina, Chapel Hill examines the hypothesis that Homo sapiens, with their high level of dependence on social behavior and cognition, could not have evolved without the neuropeptide, oxytocin. Oxytocin pathways – which include oxytocin, the related peptide vasopressin, and their receptors – are at the center of physiological and genetic systems that permitted the evolution of the human nervous system and allowed the expression of contemporary human sociality.
