Monogamy is an evolutionary trait found in male frogs, mice, voles, birds and fishes, according to research scientists from the University of Texas at Austin.
A new study, published Wednesday in the Proceedings of the National Academy of Sciences of the United States of America, examines the genetics of animals who tend to stay together for at least one mating season. Researchers broke down the DNA of five faithful animals in each species and five of their more “DTF” cousins.
Scientists discovered 24 genes associated with monogamy, relating to memory, cognitive function, learning, neural development and cell signaling. The evolutionary difference between the related pairs ranges from 2.5 to 34 billion years old, meaning the monogamous trait evolved out of one species and grew stronger in another.
Lead author Hans Hoffman told the Guardian that monogamy presents both challenges and rewards for these species: “You have to tolerate another animal next to you for an extended period of time, and that is not easy,” he says. “They may take away your food, they may take away your shelter, they may make you sick with their germs, or hurt you.”
While one partner per season may not fit in with humans’ “love of my life” style of monogamy, a similar dynamic could surely be found in many of our relationships.
