Scientists Uncover the Genetic Roots of Monogamy

Wolves, prairie voles and bald eagles commit to their partners. But in the animal kingdom, these pairs are exceptions, not the rule. Now researchers say they’ve uncovered a universal genetic signature for monogamy. The discovery suggests evolution may have also led to a common genetic basis for other complex, social behaviors.“It was surprising to see how robust the ... similarities appear to be, even though the monogamous species we selected differ quite a bit,” said Hans Hofm
