Callitrichids are well known for their communicative complexity: they have large vocal repertoires, some intentional control over their vocalizations, immatures go through a babbling phase, and they show some vocal learning: we find that different populations can have different vocal «dialects» that are socially learned. Marmosets are thus a popular model species to understand language evolution.
An intriguing possibility is that that this communicative flexibility could evolve because their readiness to share food facilitated the readiness to also share information.
