Wild sparrow study traces social behaviors in the field to specific gene

A unique study of the white-throated sparrow has identified a biological pathway connecting variation in the birds’ aggression and parenting behaviors in the wild to variation in their genome. The Emory University-led research, which comprised behavioral observations of the study subjects in the field and laboratory analyses of their gene expression in the brain, showed that variation in the expression of the estrogen receptor alpha gene strongly predicts the birds’ behavior.
