Marmosets Engage in "Polite Conversation"
According to researchers at Princeton University, marmosets will engage one another for up to 30 minutes in cooperative vocalizations -- similar to the polite conversations that humans engage in on a daily basis.
In an interview with Phys.org, Asif Ghazanfar of Princeton says that researchers were "surprised by how reliably the marmoset monkeys exchanged their vocalizations in a cooperative manner, particularly since in most cases they were doing so with individuals that they were not pair-bonded with. This makes what we found much more similar to human conversations and very different from the coordinated calling of animals such as birds, frogs, or crickets, which is linked to mating or territorial defense."
