title: Animal behavior: the family that works together stays together.
abstract: A new study shows that biparental care in frogs is more likely to evolve when tadpoles are reared under environmentally harsh conditions. Biparental care facilitates both social monogamy and genetic monogamy; frogs that work together to raise their offspring have higher mating fidelity to one another.
