COVER Infant common marmoset (Callithrix jacchus) in the act of vocalizing. For decades, it has been assumed that monkeys are born with adult-sounding vocalizations. However, Takahashi et al. report that marmoset infant vocalizations, like those of human babies, change substantially in early life and are influenced by parental interaction. See pages 688 and 734.
