Researcher Finds 'Monogamy Gene'
Continue to the storyPrairie voles are monogamous, while meadow voles aren't. Emory associate professor doctor Larry Young and his team found a gene in a part of the prairie vole's brain that wasn't in the corresponding part of the meadow vole's brain. When he put that gene into the meadow vole, guess what happened? It became -- monogamous. Humans have that same monogamy gene.
