Even among nature’s best dads, some are better than others! Marmoset dads who respond to infant distress calls quickly and early in their offspring’s life are more likely to have offspring that survive beyond 30 days and are also more likely to gain weight quicker than babies of less attentive dads. Researchers indicate this comes from the fathers having lots of interactions with their offspring as they wean from milk to solid food.
